(2) Note. This subclass provides for a projector that, as claimed in a patent to the projector, impels a burst of gaseous material or a burst of fluid material that is not further characterized as being clearly liquid or clearly gas. For a projector that impels a burst of liquid material, see the reference to Class 222 below.

56	FLUID PRESSURE:

This subclass is indented under the class definition. Apparatus wherein an object or missile is propelled or impelled by energy applied thereto, which energy is exerted by way of a force tending to compress or expand the volume of a liquid or a gaseous material.

(1) Note. As used in this and the subclasses indented hereunder (and also in those subclasses of this Classification Order which refer to this Note for a discussion of the terms), the terms "propel" and "impel", have the following meanings and connotations. Both terms have a similar meaning of causing an object to move rapidly by exerting a force thereon. However, PROPEL has the connotation of exerting a sustained force on the object, whereas IMPEL has the connotation of exerting an impulse of force thereon.

(2) Note. The pressurized fluid generated by the force described in the definition is usually a gas, such as air. The force defined may be that which compresses or tends to compress the fluid at the moment of use, or that which compresses the fluid for storage and subsequent use when the user of the apparatus causes a projectile to be launched. The source of pressurized fluid may also be a cartridge containing gas under pressure, in which instance the force is that exerted by the expansion of the gas from a punctured cartridge.

(1) Note. See (1) Note of subclass 56 for discussion of "propel" and "impel".

(2) Note. The chamber of (a) above is not necessarily separable from the missile, but can comprise a volume integral with and contained within the missile, which volume is charged with compressed gas just before the moment that the missile is launched, after which the discharge of gas from the missile propels the missile.

49	.. Gravity fed:

This subclass is indented under subclass 45. Devices, in which the feeding of the projectiles takes place by the action of gravity.

SEE OR SEARCH THIS CLASS, SUBCLASS:

47,	for gravity fed magazines particularly adapted for use with disk targets.

50	... Having cut-off:

	This subclass is indented under subclass 49. Devices, in which the continuous feeding of projectiles is prevented by some means which permits them to pass into position only at a certain desired period or position of the other parts of the projector. This cut-off must be something other than the driving or impelling member of the projector.

51.1	.. Mechanical projectile feed:

This subclass is indented under subclass 45. Subject matter, in which a projectile is moved from a magazine to the ready-to-fire position by means of a chute, ramp, conveyor, linkage, or other mechanical means.

SEE OR SEARCH CLASS:

42,	Firearms, subclasses 49.01+ for magazines of similar nature for use with a firearm.

52	... Spring:

	This subclass is indented under subclass 51.1. Devices, operated or driven by a spring.

53	.... Having cut-off:

	This subclass is indented under subclass 52. Devices, in which the continuous feeding of projectiles is prevented by some means which permits them to pass into position only at a certain desired period or position of the other parts of the projector. This cut-off must be something other than the driving or impelling member of the projector.

53.5	... Fluid projectile feed:

	This subclass is indented under subclass 51.1. Subject matter, in which a projectile is moved from a magazine to the ready-to-fire position by hydraulic or pneumatic means.

81	. Means for producing projectile spin or deflection:

	This subclass is indented under subclass 80. Device which imparts a rapid rotation to a missile about an axis that is substantially coincident with the line of movement of the missile, or which diverts a moving missile from one trajectory to a different trajectory as it is being impelled from a projectile-impelling apparatus.

82	. Means for feeding projectile or ejecting cartridge:

This subclass is indented under subclass 80. Device which moves a missile relative to a projector thereof before it is impelled therefrom, such movement being for the purpose of locating the missile in proper position to be impelled, or which removes from a projector the cartridge of a projectile-carrying cartridge after the launching of a missile from the cartridge.

(1) Note. The term "projectile-carrying cartridge" is defined in part (b) of the definition of subclass 57 above.

83	. Projector barrel:

	This subclass is indented under subclass 80. Device in which the particular portion is a tube on the projectile-impelling apparatus, which tube guides a missile during the short time that the missile is within the apparatus just before it is fully launched therefrom.

84	.. On convertible or adjustable projector:

This subclass is indented under subclass 83. Device in which one tube can be exchanged for another tube, or in which a tube can be varied in dimension, whereby missiles of varying dimensions can be launched from a particular projectile-impelling apparatus, or in which a particular tube may be mounted on one form of stock (e.g., to simulate a hand gun) or mounted on another form of stock (e.g., to simulate a rifle).

85	.. With surrounding cylinder:

	This subclass is indented under subclass 83. Device in which the tube that guides the missile is enclosed along substantially its entire length by a second tube spaced radially from the guiding tube.

86	. For archery projector:

This subclass is indented under subclass 80. Device in which the particular portion is part of an apparatus wherein a user impels an arrow from a bow.

(1) Note. For purposes of the subclasses indented hereunder, a "bow" is defined as a strip of elongated resilient material, usually curved or bent, having a "string" connecting the two ends of the strip. In use, the bow is grasped by a "handle" and a portion of the string is pulled away from the handle with an arrow between the string and the handle. A groove or "nock" in the rear end of the arrow is fitted to the string so that when the string is released energy which has been stored in the bow by pulling apart is released and the arrow is impelled.

87	.. Bow sight:

This subclass is indented under subclass 86. Device in which the particular portion is a component that aids a user to properly aim an arrow towards its target.

SEE OR SEARCH CLASS:

33,	Geometrical Instruments, subclass 265 for a sighting means, per se.

88	.. Bow handle or attachment thereto:

This subclass is indented under subclass 86. Device in which the particular portion is a bow handle, or a component fastened thereto.

(1) Note. See (1) Note to subclass 86 for a discussion of the terms "bow" and "handle" in relation to other archery terms.

89	... For stabilization thereof:

	This subclass is indented under subclass 88. Device in which the portion or component tends to prevent excess motion of the bow, especially during launching of an arrow therefrom.

90	.. Bow string or attachment thereto:

This subclass is indented under subclass 86. Device in which the particular portion is a bow string, or a component fastened thereto.

(1) Note. See (1) Note to subclass 86 for a discussion of the terms "bow" and "string" in relation to other archery terms.

91	... Nock-point locator:

This subclass is indented under subclass 90. Device in which the portion or component serves to position the nock of an arrow relative to its correct position on the strings to properly launch the arrow.

(1) Note. See (1) Note to subclass 86 for a discussion of the terms "nock" and "string" in relation to other archery terms.

92	... Silencer:

	This subclass is indented under subclass 90. Device in which the portion or component tends to reduce the noise that normally is caused by vibration of a string after release thereof.

1	MISCELLANEOUS:

This subclass is indented under the class definition. Device not classifiable above.

(1) Note. This subclass includes means for imparting rapid rotation to a propellor-like object which propels itself through the air because of its shape and rotation, or a device wherein gravity or a weight facilitates the launching of a missile.

900	LIMB TIP ROTATABLE ELEMENT STRUCTURE:

	Collection of documents disclosing reels, cams, eccentrics, pulleys, wheels, etc., which are mounted at or near an extreme end of a bow stave in such fashion as to be operatively associated with a means for increasing the shooter"s mechanical advantage, e.g., the pulleys of a compound bow.
