SECTION I - CLASS DEFINITION

This class includes:

Apparatus or means relating to the type of amusement, recreational, or play activities commonly known as games or sports (a) in which one or more players or participants use a ball, missile, stream of water, or any other such body which occupies physical space and can be touched and thereby felt by the one or more players or participants (i.e., a tangible body) such that, during play of a game or sport, the ball, missile, or other such tangible body is thrown, rolled, shoved, impelled, propelled, projected, or otherwise put into motion by a nonexplosive force so as to achieve an objective set forth by rules defined for the particular game or sport and (b) wherein the result of playing such a game or sport can be indicated according to rules defined for the particular game or sport;

Devices which are ancillary or appurtenant to the types of games or sports included herein, unless they are provided for elsewhere.

(1) Note. The ball, missile, or other such tangible body is (a) usually initially put into motion by an external force supplied either by a player of the game or sport or by other nonexplosive means (e.g., by a mechanically operated device, etc.) and (b) usually continues in motion under its own inertia (in the absence of intervention or interception by another external force or by a body) after having been put into motion. However, a self-propelled ball, missile, or other such tangible body may be included herein provided it is intended to be used in the play of a game or sport.
(2) Note. In regard to devices or implements for striking, impelling, launching, or, otherwise, projecting a game projectile, the following applies: (a) Any projector device or implement which is combined with any other device, apparatus, or component used for a game or sporting purpose is included herein, (b) a striking type of projector implement which is used for a game or sporting purpose (such as a club, bat, racket, paddle, mallet, stick, etc.) and which is carried by (e.g., handheld) and manually manipulated by a user to strike and thereby project a game projectile such that substantially all of the force used to project the projectile is supplied by the user is, per se, included herein, (c) a throwing or flinging type of implement or device which is used for a game or sporting purpose and which is specifically adapted and intended to be used to both project a game projectile and to catch a game projectile after it has been projected (i.e., a combined projector-catcher device) is, per se, included herein, and (d) any projector device or implement (other than one which is operated by explosive means) which is used for a game or sporting purpose and which is specifically adapted and intended to project a game projectile so that it travels upon a playing surface substantially at all times (i.e., the projectile is in contact with and moving over the playing surface either upon or immediately after projection) is, per se, included herein. Centrifugally or mechanically operated device or implement, per se, for projecting a projectile into the air, which device or implement may be used to project a game projectile is located elsewhere. See References to Other Classes, below.
(3) Note. Although not generally used during the play of the types of games or sports included herein, devices or implements which are used by a player to practice or train for one of the types of games or sports included herein are provided for in Class 473. Since such practice and training devices or implements are designed to enable a player to improve or perfect his or her physical skills (e.g., motor skills, coordination, etc.) in the playing of any aspect of the game or sport for which it was designed for, they are included in Class 473 on the basis that they are ancillary or appurtenant to the types of games or sports provided for herein.
(4) Note. A ball, marble, die, top, etc. which is intended to be used as a chance device alone or intended to be used as part of a chance device or game apparatus (e.g., a die used as a chance device to generate a random number, letter, etc., a marble used as part of a roulette-wheel apparatus, or a die used to generate a number, letter, etc. during play of a board game apparatus, etc.) is not considered to be a projectile proper for Class 473 and is, therefore, excluded. Likewise, a marble or the like used to operate a "Rube Goldberg"" type of device, which device being used to play a game (for example, used in the play of a board game) is not considered to be a projectile proper for Class 473 and is, therefore, excluded. An object (often a representation of a horse, vehicle, person, etc.) which is propelled during play of a propelled racing game is not considered to be a projectile proper for Class 473 and is, therefore, excluded.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

This class is specific under Class 463, Amusement Devices: Games, which, in turn, is specific under Class 472, Amusement Devices.

Class 273, Amusement Devices: Games, is currently being reclassified through a series of stages. Upon completion of this reclassification, Class 273 will be abolished and replaced either by Class 473 or by Class 463, Amusement Devices: Games. Until this reclassification is completed, the portions of Class 273 which are relevant to Class 473 are to be considered an integral part of Class 473. Specifically, subclasses 108+ and 317+ of the Class 273 schedule are to be considered as following in hierarchy after the last occurring subclass in the Class 473 schedule. The rest of the subclasses of the Class 273 schedule are, for the most part, to be considered as following in hierarchy after the last occurring subclass in the Class 463 schedule. Also, since Class 273 has not been completely screened for all patents properly classifiable in present subclasses of Class 473, appropriate subclass(es) in Class 273 should be considered for search purposes until such time that Class 273 is finally abolished.

LINE WITH CLASS 463

The relationship between Class 473 and Class 463 is that Class 463 is the residual class for games, while Class 473 provides only for those specific types of games in which a ball, missile, or other such tangible projectile (other than a simulation or representation thereof) is used during play thereof. Accordingly, if a game (or a game component thereof) which uses a ball, missile, or other such tangible game projectile (other than a simulation or representation thereof) during play thereof is claimed or solely disclosed, then classification is in Class 473, otherwise, classification is in Class 463 or in the appropriate subclasses of Class 273, Amusement Devices: Games, which follow behind the subclasses of Class 463. However, note that Class 463 provides for (a) a game apparatus or means which uses a simulation or representation of a tangible projectile (e.g., a light-ray simulation of a projectile, a computer generated representation of a projectile, etc.), (b) a propelled racing game in which an object (often a representation of a horse, vehicle, person, etc.) is propelled during play thereof, and (c) a chance device, either per se or in combination with a game which does not use a tangible projectile, whether or not a projectile is included therein, and even if it is not a game or subcombination element of a game (these are, for the most part, still located in Class 273). See also (4) Note above for further elaboration of exceptions to what is provided for in Class 473.

LINE WITH CLASS 345

See Class 463, Amusement Devices: Games, References to Other Classes, in the Search Class note to Class 345 for an elaboration of the line between Class 345 and Class 463, the parent class for Class 473. A selectively controlled visual display system combined with a game component of a game provided for in Class 473 (e.g., a golf club, golf ball, tennis court, tennis court net, etc.) or with a practice or training device therefor (e.g., a golf club swing training device, baseball bat swing training device, etc.) is proper for Class 473.

LINE WITH CLASS 434

Class 473 and subclasses 108+ and 317+ of Class 273, Amusement Devices: Games, contain devices which are to be used for practice by, or for perfecting the physical skill of, a person who already knows how to play the game, sport, or the like. Class 434 contains devices which are to be used for instructing an unknowledgeable person in some aspect of the game, sport, or the like. A device which is used both for instruction and for practice or perfection of game skills is originally placed into Class 434 and cross-referenced into the Class 463 group of game classes (i.e., Classes 463, 473, or 273).

LINE WITH CLASS 446

Class 446, Amusement Devices: Toys, for a device known as a toy whose principle purpose is for the amusement or recreation of a child. If the device is used for the amusement or recreation of a child and is also a game component (i.e., used in a competition or contest), then it is placed into the Class 463 group of game classes (i.e., Classes 463, 473, or 273).

SUBCLASSES

[List of Patents for class 473 subclass 1]    1BILLIARDS OR POOL:
 This subclass is indented under the class definition.  Subject matter relating to a game which generally involves a horizontally disposed, planar playing surface bounded and defined by raised carom rails (i.e., bumper rails) for confining on the playing surface a plurality of balls which are being projected over the playing surface either into one another or rebounded off of the carom rails; the playing surface either (a) is continuous and has a continuous carom rail rim so that it is devoid of any pockets or other ball receiving receptacles (i.e., a billiard playing surface) or (b) has one or more pockets or receptacles adapted to receive therein or pass therethrough one or more of the balls (i.e., a pool or pocketed playing surface); in playing the game, at least one ball, commonly known as the cue ball, acts as a secondary projecting device and is used to strike and move over the playing surface one or more of the other balls, commonly known as object balls, which act as targets for the cue ball, the cue ball is first forcibly struck by a player aiming and manipulating a first projecting device, commonly known as a cue or cue stick, so as to project the cue ball either directly into engagement with the one or more of the object balls or by first banking or rebounding it off of one or more of the carom rails and then into engagement with the one or more of the object balls so as to move and either position the object balls in a specified arrangement on the playing surface or to pocket them, whereby the player may achieve a score according to the rules specified for the game.
(1) Note. In a game of this type balls are usually used but it is to be understood that ball equivalents may be used in their stead provided that they act, other than the fact that they probably do not roll, in the same manner that balls would in playing the game. That is, the ball equivalents should move one another about over the playing surface and should carom or rebound off of one another or the carom rails in the same manner as balls would.
(2) Note. Usually, the initial projecting device (i.e., the cue) used to strike the cue ball is a long, tapering, tipped rod or stick but other types of cues that may be used include a mechanically operated cue, a mallet type cue, etc.

 This subclass is indented under subclass 1.  Subject matter comprising either (a) a means to enable a player to improve or perfect his or her skills in the playing of any aspect of the game, or (b) a means to assist a player in determining the proper alignment or position that the cue device must be in so that the cue ball projected thereby moves in the desired direction, or (c) a means to assist a player in calculating or otherwise determining the direction or angle that the cue ball must be projected in order for it to, in turn, project the desired object ball or balls in the desired direction.

SEE OR SEARCH THIS CLASS, SUBCLASS:

42+,for a device known as a cue rest or bridge. Although cue rests or bridges can somewhat be interpreted as assisting the player in aligning the cue during shots, they are not included here because their primary function is to aid in supporting the cue during difficult shots such as ones in which the player has difficulty in extending his or her cue supporting and guiding hand close enough to the cue ball to make a reasonably accurate shot. That is, cue rests or bridges do not primarily function to enable a player to determine the proper alignment or position of the cue or the proper direction or angle that a cue ball must be projected to achieve the desired result.

 This subclass is indented under the class definition.  Subject matter relating to a directly interactive and competitive game or sport in which two or more opposing players or teams of players located upon or within a playing area manipulate or otherwise use a game projectile during play of the game or sport, and over which playing area at least one of the two or more opposing players or teams, in trying to achieve the game objective, moves, either while manipulating the projectile or while interacting with, reacting to, or responding to another player who is manipulating the projectile or to movement of the projectile itself whenever it is free of the players" direct control, which game or sport includes any one of or a combination of the following: (a) a game component (e.g., a convertible goal or target device, etc.) which has a configuration that is adapted and intended to be changed so that it, in one configuration thereof, is a game component which is intended to be used in or for a game or sport included herein and, in another configuration thereof, is either a game component or a practice or training device that is intended to be used in or for a diverse type of game or sport which also uses a game projectile, which diverse type of game or sport is either a different game or sport included herein or a game or sport not included herein; (b) a kit of parts which is adapted and intended to be assembled or reassembled into a first game component intended to be used in or for a game or sport included herein and into either a second game component or a practice or training device which is intended to be used in or for a diverse type of game or sport which also uses a projectile, which diverse type of game or sport is either a different game or sport included herein or a game or sport not included herein; (c) a game component (other than a projector or projectile, per se) which is used during play of a game or sport included herein; or (d) an ancillary device or means (e.g., a cover for a playing field or court, etc.) which is adapted and intended to be used with or for a game component during the times that the game or sport is not being played (i.e., before or after the game or sport is played or during a time out) unless it is provided for elsewhere.
(1) Note. A game or sport of the type to be included in this and the indented subclasses, must involve a game projectile, whether or not claimed. The projectile used by the two or more opposing players or teams of players may be manipulated in such a manner that it may be thrown, carried, struck, kicked, pushed, etc. by any portion of a player"s body or by a projector device carried by a player as dictated by the rules defined for the game. However, the projectile must, at some point in time during play of the game or sport, be free of the player"s direct control as, for example, when the projectile is thrown or otherwise projected either through the air or for movement over the playing area toward a goal or target or toward another player.
(2) Note. The statement "directly interactive and competitive game or sport" referred to above is defined herein to mean that the opposing players or teams of players play the game or sport generally simultaneously (other than at such times as, for example, a penalty kick in a soccer game, etc.). Thus, for example, a game or sport in which a player, located upon or within a playing area, projects a projectile toward a goal or target and subsequently moves over the playing area to the location of the projected projectile for retrieval or reprojection thereof (as in the games of hopscotch, croquet, golf, horseshoes, etc.) is not considered to be a playing field or court game or sport as defined herein and is, therefore, excluded because the player is not moving over the playing area either while manipulating the projectile or while interacting with, reacting to, or responding to another player who is manipulating the projectile or to movement of the projectile itself. Further, most simple target games in which the players take turns in projecting or impelling a game projectile toward a goal or target in order to achieve a score higher that another player, although a competition in a broad sense, are excluded from these subclasses because the players are not directly interacting with another player at the same time during play of the game (i.e., there is no interference from an opposing player of the game) or because a player and his opponent are not both moving over the playing area at the same time during play of the game.
(3) Note. A simple game of throw-and-catch in which the players may incidentally move over a playing area is not considered to be a playing field or court game or sport and is, therefore, excluded because the movement is caused by unintentional inaccuracy of the thrower in attempting to throw the projectile to the catcher.
(4) Note. A game component which is used in a playing field or court game included herein, is defined as a device or means which is used during the times that the game or sport is being played. Although the following list is not to be considered as exhaustive, such a game component may include any of one of the following devices or means: (a) a playing area of indeterminate extent or a playing area defined by a visually (e.g., marked) or otherwise sensory distinct enclosing peripheral boundary or by an enclosure. However, this type of game component is, per se, excluded from these subclasses since it is classifiable elsewhere. That is, this type of game component, to be included here, must be combined with another game component which is included herein. See (6) Note below for a further discussion of this line. Such additional game component may be a court dividing net as in a tennis court, another interior playing field or court dividing means that breaks the playing area into compartments, sub-areas, or sections, as the ten yard line markings on a football field, a goal or target device, a game projectile, a projectile impelling device manipulated by a player, etc.; (b) a structure, per se (e.g., a net, barrier, etc.) or a visually or otherwise sensory distinct means, per se (e.g., a marked line, etc.) which is adapted and intended to break the playing area into compartments, subareas, or sections; (c) a goal or target, per se, for providing a point of aim for a game projectile projected thereat by a player; (d) a player-held and powered, nonmechanical implement adapted and intended to project a game projectile (e.g., a bat, tennis racket, polo mallet, hockey stick, etc.). However, this type of game component is, per se, excluded from these subclasses since it is classifiable elsewhere. That is, this type of game component, to be included here, must be combined with another game component which is included herein; (e) a game projectile (e.g., a ball, hockey puck, badminton shuttlecock, etc.). However, this type of game component is, per se, excluded from these subclasses since it is classifiable elsewhere. That is, this type of game component, to be included here, must be combined with another game component which is included herein; (f) a football kicking tee, per se, which is used once in a while during play of an American football game; (g) a means, per se, used by a player when projecting a game projectile for enhancing the movement of the projectile after projection thereof (e.g., a means that a player uses to assist in causing a pitched baseball to curve during flight); (h) a base, per se, adapted and intended to be located on or within a playing area used in a game involving base running (e.g., a base to be located at a corner of the diamond-shaped playing area used in playing the game of baseball, etc.); (i) a strike-zone detector (e.g., a detector for determining whether or not a ball pitched toward a batter located in the vicinity of home plate is within the strike zone in a baseball-type game, etc.) provided that it is claimed in combination with another game component classifiable herein (e.g., with the home plate, etc.); or (j) a boundary detector (e.g., a ball-out-of-bounds detector for use on a tennis court, etc.) provided that it is claimed in combination with another game component classifiable herein (e.g., with the tennis court, tennis court net, etc.).
(5) Note. An accessory (i.e., an ancillary device or means) is generally not considered to be a game component unless it is convertible or is part of a kit of parts, as specified in parts (a) and (b) of the definition above. An accessory, per se, intended to be used with or for a game component used in a game or sport included herein, is often classified with the component it is intended to be used with or for, unless it is provided for elsewhere. For example, a press for a tennis racket is included under the subclasses providing for the tennis rackets which, in turn, is included under the subclasses providing for player-held and powered, nonmechanical projectors for projecting an aerial projectile into or through the air by striking. On the other hand, a cover, per se, for a playing field or court included herein is classified herein by itself near the end of the group of subclasses under this mainline subclass. Also, it should be kept in mind that some accessory devices or means are classifiable elsewhere as, for example, in other classes.
(6) Note. The playing area itself, the peripheral boundary or enclosure itself, or both may be included in this and the indented subclasses provided that at least one other game component intended to be used in or for a playing field or court game or sport as defined above is also claimed in combination therewith. For example, a ball or a goal combined with a particular floor structure, a walled enclosure combined with a game racket, or a football field combined with a peripheral boundary marking and with an interior yard line marking would be included herein. However, a particular floor, field, or court structure per se, a particular walled enclosure per se, a peripheral boundary marking per se, or a particular floor, field, or court structure combined only with a particular walled enclosure or peripheral boundary marking would not be included herein.
(7) Note. A means which is specifically adapted and intended to enable a player of a playing field or court game included herein to improve or perfect his or her physical skills (e.g., motor skills, coordination, etc.) in the playing of any aspect of the game or sport (i.e., a practice or training device) is included herein.

52Static Structures (e.g., Buildings),   for an arena, stadium, or other building structure of general utility.
124Mechanical Guns and Projectors,   for a mechanically or centrifically operated projector device or implement, per se, which is used to project a projectile into or through the air as, for example, an archery bow, a slingshot, a baseball pitching machine, a tennis ball throwing machine, a clay pigeon throwing trap, or a fluid pressure, pinch, or centrifugally operated (e.g., a sling, etc.) type of projector device, etc. And see the (3) Note in the class definition of Class 473 above.
273Amusement Devices: Games,   for another game which also uses a tangible projectile, particularly subclasses 108+ for surface projectile game or apparatus therefor (other than a projectile, per se), subclasses 108.1+ for such a surface projectile game that mimics some aspect or the scoring of a playing field or court game such as the sports known as baseball, basketball, football, hockey, tennis, soccer, etc., subclass 129 for a projector used to project a projectile in such a surface projectile game, subclasses 317+ for an aerial projectile game or apparatus therefor (other than a projectile per se or a device or implement, per se, for projecting such a projectile), and subclasses 317.1+ for such an aerial projectile game that mimics some aspect or the scoring of a playing field or court game such as the sports noted above. Class 273 is currently undergoing reclassification and will eventually be replaced either by this Class 473 or Class 463, Amusement Devices: Games. Until this reclassification is completed, the subject matter of Class 273 relating to games or sports which use a tangible projectile is to be considered as following in hierarchy the last occurring subclass of the Class 473 schedule. Specifically, subclasses 108+ and 317+ of the Class 273 schedule are to be considered as following in hierarchy after the last occurring subclass in the Class 473 schedule.
463Amusement Devices: Games,   for a game apparatus or means, in general. The relationship between Class 473 and Class 463 is that Class 463 is the residual class for games, while Class 473 provides only for those specific types of games in which a ball, missile, or other such tangible projectile (other than a simulation or representation thereof) is used during play thereof. Accordingly, if a game (or a game component thereof) which uses a ball, missile, or other such tangible game projectile (other than a simulation or representation thereof) during play thereof is claimed or solely disclosed, then classification is in Class 473; otherwise, classification is in Class 463 or in the appropriate subclasses of Class 273, Amusement Devices: Games, which follow behind the subclasses of Class 463. However, note that Class 463 provides for (a) a game apparatus or means which uses a simulation or representation of a tangible projectile (e.g., a light-ray simulation of a projectile, a computer generated representation of a projectile, etc.), (b) a propelled racing game in which an object (often a representation of a horse, vehicle, person, etc.) is propelled during play thereof, and (c) a chance device, either per se or in combination with a game which does not use a tangible projectile, whether or not a projectile is included therein, and even if it is not a game or subcombination element of a game (these are, for the most part, still located in Class 273).
472Amusement Devices,   subclasses 92+ (a) for the structure or composition of a playing surface, per se (b) for the structure or composition of a peripheral boundary structure, marking, or enclosure per se, for such a playing surface, or (c) for the combination of only a playing surface and a peripheral boundary structure, marking, or enclosure; all of the above of which are limited to use for an athletic or exhibition event such as, for example, the playing of a game or sport thereon or therein. Also see the Search Notes appended thereto.
482Exercise Devices,   for a device adapted and intended to be used by a player of a playing field or court game for the sole purpose of strengthening or exercising his or her muscles so as to improve play of the game. If the device is adapted to be used along with a game component (as, for example, a weight to be attached to a baseball bat or a kicking exercise device intended for use with a soccer ball or football, etc.), then the device is classifiable in Class 473. Also, if the device is intended to be used either for exercising or for warmup by the player, then the device is classifiable in Class 473.
602Surgery: Splint, Brace, or Bandage,   for a device adapted and intended to be used for the treatment of a disorder or injury of a portion of the human body, particularly subclasses 5+ for an immobilization appliance (e.g., a splint, brace, etc.) for treating a disorder or injury of a body portion.
  
[List of Patents for class 473 subclass 416]    416Having game element combined with or convertible to game element or practice or training device for different type of projectile game:
 This subclass is indented under subclass 415.  Subject matter comprising either (a) a game component which is used in playing a playing field or court game in accordance with a first set of rules combined on a common support or frame with another game component, or a portion thereof, of a different construction which is used to play or practice any other game or sport in accordance with a different set of rules or (b) a collection of components which are so constructed that at least some of the components may be and are specifically intended to be assembled, reassembled, or adjusted to form a game component which is used in playing a playing field or court game in accordance with a first set of rules and at least some of which collection of components are specifically intended to be assembled, reassembled, or adjusted to also or alternatively form another game component, or a portion thereof, which is used to play or practice any other game or sport in accordance with a different set of rules (e.g., a collection of components which can be assembled to form a soccer goal and reassembled to form a football goal).
(1) Note. The second game component, with which the game component used in a playing field or court game is combined or which may be alternatively formed from the collection of components used to form the game component used in a playing field or court game, need not necessarily be used in a playing field or court game (e.g., a basketball goal which is combined with a dart board).
  
[List of Patents for class 473 subclass 417]    417Means removably supporting projectile in position to be struck and thereby projected by player (e.g., batting tee, etc.):
 This subclass is indented under subclass 415.  Subject matter comprising a structure adapted to support a game projectile relative to the ground so that it may readily be struck and thereby impelled by a player of a playing field or court game or by a player practicing or training for such a game, which supporting structure is in the form of (a) a means having an underlying projectile receiving seat upon which the projectile is intended to removably rest, (b) an overhead member having means for removably suspending the projectile therefrom, or (c) an overhead member for engaging the top of the projectile so that the projectile is removably held between the overhead member and either the ground or an underlying member or mechanism upon which the projectile removably rests or by which the projectile is removably held.
(1) Note. The support structure may be an upwardly extending column or stream of fluid, the seat being formed when and where the fluid impinges upon or interacts with the projectile.
(2) Note. The term "removably" as it is used above means that the projectile (a) is merely freely resting upon the support structure, (b) is releasably attached to the support structure (e.g., by means of a tether releasably supporting a projectile in suspended position, etc.), or (c) is releasably held by the support structure (e.g., held between an overlying member and the ground or an underlying member or mechanism, etc.).

 This subclass is indented under subclass 417.  Projectile supporting structure in the form of either (a) an overhead member having means for removably suspending the projectile therefrom or (b) an upwardly extending column or stream of fluid, the seat being formed when and where the fluid impinges upon or interacts with the projectile.
(1) Note. If the projectile supporting structure provides both an underlying seat upon which the projectile rests and an overhead means for also supporting a projectile from above as, for example, for supporting a tip of a football in an upwardly facing direction, then the projectile is not considered to be suspended and is, therefore, excluded from this subclass. That is, a projectile that is supported in a suspended fashion is considered to have no underlying means of support.

 This subclass is indented under subclass 423.  Tethered projectile device wherein the projectile is mounted to the elongated member by means allowing it to shift position along the length of the elongated member.
(1) Note. A device in which the elongated member itself is comprised of two or more relatively sliding sections will be found in subclass 423 above unless the projectile itself is also slidable relative to at least one of the sections.
  
[List of Patents for class 473 subclass 429]    429Tether pivotally attached for orbital revolution:
 This subclass is indented under subclass 423.  Tethered projectile device wherein a portion of the elongated means, remote from the point of its attachment to the projectile, is secured to the anchor means by a pivotal connection which permits the tether and the projectile to orbitally revolve about the anchor means (or at least about the connection to the anchor means) similar to the manner in which the earth orbitally revolves about the sun.
(1) Note. If the tether is of the type comprising a flaccid cord, rope, etc. from which the projectile is suspended and the connection to the anchor means is by means of swivel which permits the tether to rotate only about its own axis similar to the manner in which the earth rotates about its own axis, then this type of tether is excluded from this subclass.
(2) Note. If the tether is of the type comprising a flaccid cord, rope, etc. from which the projectile is suspended, then the portion of the tether which is secured to the anchor means must itself be capable of rotating about an axis (e.g., by means of a rotatable collar, ring, swivel, eyelet, etc. or by means of a loosely fitting looped portion thereof). A flaccid cord, rope, etc., which is tightly tied or knotted to a portion of the anchor means is not considered to be a pivotal connection proper for this subclass as indicated in the Search note below.

[List of Patents for class 473 subclass 505]    505PLAYER HELD DEVICE FOR BOTH PROJECTING AND CATCHING AERIAL PROJECTILE; PART THEREOF OR ACCESSORY THEREFOR (I.E., COMBINED PROJECTOR-CATCHER DEVICE):
 This subclass is indented under the class definition.  Subject matter (a) comprising a handheld or body-mounted implement for throwing, impelling, launching, or otherwise projecting a projectile into or through the air and wherein the implement is either (1) also used to capture or trap a projectile already moving through the air, or (2) includes an additional means to capture or trap a projectile already moving through the air; (b) comprising a constituent part of such an implement; or (c) comprising an ancillary means adapted and intended to be used with or for such implement not elsewhere provided for.
(1) Note. The terms "catch," "capture," and "trap" as used herein mean that the primary function of the projector-catcher implement is to be so manipulated by the user to stop or intercept a game projectile during its flight through the air and that the implement carries and holds the intercepted projectile therein or thereon so that it may again be thrown, impelled, launched, or otherwise projected into the air from the implement upon manipulation thereof by the user. However, the implement may include means so that it may, at times, be also used to scoop a projectile off the ground so as to project it into the air provided that the implement also has means to carry or hold the projectile therein or thereon prior to projection thereof.
(2) Note. A "catcher" as defined herein is distinguished from a ""target" in that a catcher is manipulated by the user in an effort to catch or intercept and trap the projectile while a target is merely an aiming point for a projectile projected thereat. Any movement of a target is intended to make the target more difficult to be struck by a projectile aimed and projected thereat.
(3) Note. The term "catching" embraces catchers in the form of pocket-type receptacles (with or without outlet passages), open-bottomed pockets which trap and retain a projectile therein (i.e., apertured catchers which have apertures smaller than the projectile), and rodlike or hooked appendages.
(4) Note. These combined projector-catcher implements may be used in a number of ways. For example, an impaling type of projector-catcher implement consisting merely of a rodlike member having a gripping portion may be used by (a) a user to launch a projectile removably impaled upon the rodlike member into the air and subsequently manipulated to catch (i.e., impale) the launched projectile upon the same rodlike member, (b) a user having two such rodlike members, one in each hand, and the projectile is launched by the user from the rodlike member in one hand to be caught by the rodlike member in the other hand, or (c) two or more users therefor, each having one such rodlike member and the projectile is launched into the air from the rodlike member held by one user to be caught by (i.e., impaled upon) the rodlike member held by another user.

[List of Patents for class 473 subclass 507]    507Having pocketed catcher:
 This subclass is indented under subclass 506.  Subject matter wherein the catcher part of the implement is either (a) in the form of a closed-bottom receptacle which is intended to stop and retain the projectile therein, or (b) in the form of a through aperture which is somewhat smaller in dimension than the projectile so as to stop, trap, and retain the projectile therein.
  
[List of Patents for class 473 subclass 508]    508Having elastic tether:
 This subclass is indented under subclass 507.  Subject matter wherein the tether is a resilient flexible member or is secured to a resilient means (e.g., a spring-powered rewinding mechanism, etc.) attached to the implement.
  
[List of Patents for class 473 subclass 509]    509Having projectile conducting means between separate entrance and exit (e.g., continuous orbit, etc.):

[List of Patents for class 473 subclass 510]    510Both projector and catcher are pocketed:
 This subclass is indented under subclass 505.  Subject matter wherein either (a) the projector part is also used as the catcher part and is in the form of either a closed-bottom receptacle or an apertured receptacle, the aperture of the apertured receptacle having a dimension somewhat smaller than the projectile, whereby the receptacle, in performing its catching function, is intended to stop, trap, and retain the projectile therein, or (b) the projector part and the catcher part are separate portions of the implement and are both in the form of a closed-bottom receptacle, an apertured receptacle, or a combination of both a closed-bottom receptacle and an apertured receptacle, the aperture of the apertured receptacle having a dimension somewhat smaller than the projectile, whereby the catcher part of the implement, in performing its catching function, is intended to stop, trap, and retain the projectile therein.
  
[List of Patents for class 473 subclass 511]    511With mechanical projection:
 This subclass is indented under subclass 510.  Subject matter wherein the projector part comprises or includes a mechanically operated means associated with the receptacle for achieving or assisting the impelling or launching of a projectile into the air.
(1) Note. Also included in this subclass are projector-catcher implements formed from a flexible sheet means which is flexed by the user to achieve or assist the propelling or launching of a projectile resting on the sheet means. The flexible sheet means either has a closed-bottom receptacle formed therein or located thereon so as to form a closed-bottom receptacle. The flexing of the sheet means by the user (e.g., the pulling upon the ends of the sheet means so as to tension or stretch it) causes a projectile resting thereon to be propelled or launched into the air and, therefore, constitutes a mechanically operated means to propel or launch a projectile.
  
[List of Patents for class 473 subclass 512]    512Pocket-to-pocket type:
 This subclass is indented under subclass 510.  Subject matter wherein the receptacle of the projector part and the receptacle of the catcher part are separate portions of the implement so that the projectile is launched into the air from the projector-part receptacle and caught by the catcher-part receptacle.
(1) Note. The catcher part of the implement may comprise plural receptacles.
  
[List of Patents for class 473 subclass 513]    513Having pocket with laterally facing opening (e.g., lacrosse stick, jai alai cesta, etc.):
 This subclass is indented under subclass 510.  Subject matter wherein the projector part and the catcher part are combined into a single closed-bottom receptacle which is used both to catch a projectile moving through the air and to propel or launch the projectile back into the air and wherein the implement includes an elongated handle member attached to and extending outwardly from the closed bottom receptacle such that the open portion of the receptacle faces in a direction generally perpendicular to the longitudinal axis of the handle member, whereby the implement as a whole has a general configuration somewhat similar to a spoon-shaped utensil.
(1) Note. The closed-bottom receptacle which constitutes both the projector and catcher parts of the implement may be quite large relative to the projectile and this receptacle may itself have a secondary closed-bottom receptacle formed therein for holding and retaining a projectile at rest therein. Many lacrosse sticks are exemplary of this type of implement. When the implement is manipulated to project a projectile, a projectile resting in the secondary receptacle is moved out into the main receptacle and projected therefrom, mainly by centrifugal forces. When the implement is manipulated to catch a projectile moving through the air, the implement is manipulated so that the bottom of the main receptacle intercepts (thereby stopping) the flight of the projectile, whereupon the projectile drops by gravity into the secondary holding receptacle so that it may again be projected.
