Click here for a printable version of this file

SECTION I - CLASS DEFINITION

Apparatus, device, implement or method for placing or displacing particular articles in a particular manner or with reference to a particular support, for loading or unloading vehicles with materials or objects in general, charging or discharging furnaces, bins, chambers, or other receptacles, stacking or piling articles or materials, also combinations of general types of carriers or forwarding mechanisms, which types, per se, are separately classified elsewhere, and general types of elevators, cranes, or hoists when associated with special means for handling the load to place it on the carrier or remove it therefrom.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

Combined conveyors, carriers, and forwarders of types now included under Class 198, Conveyors: Power-Driven, are to be found in Class 198; but combined carriers, the separate elements of which are in different classes, are provided for in this class.

Vehicles in which the body is merely moved or tilted to dump by gravity are classified in Class 298 or in Class 105, particularly, subclasses 238.1+; however, in regard to Class 298, see also the reference thereto in subclass 469 of this class (414).

For handling where manipulation during the progress of manual work is involved or for handling including the engagement of more than one part to aid in manual assembly of such parts, see Class 269, Work Holders. The fact that the article handled is assembled manually with an abutting receiver will not exclude a handling mechanism from Class 414.

(1) Note. While it is commonplace in the parking facility art, usually as a matter of convenience or expediency, to drive a vehicle onto or off from a site, this and the indented subclasses are limited to providing only for those facilities which are so constructed that some or all of the movement of a vehicle is possible only if the vehicle possesses one or more capabilities of the nature described. In other words, this subclass does not extend to include a mere forward or backward movement of a vehicle on a level surface because movement of that nature may be accomplished manually if necessary. (2) Note. A patent is proper for original placement here if there is any suggestion in the claims of structure which necessitates self-propellability, etc., on the part of the vehicle. (3) Note. A patent is properly cross-referenced here when it is clear that, in spite of the absence of structure for this subclass, an intention exists that an operator remain with the vehicle during at least a portion of the time while it is being moved to or from a site.

(1) Note. The following observations may be made concerning the movable site concept: (a) the phrase "device or element" embraces structures ranging from a driven carrier (e.g., conveyor, elevator, etc.) to a single supporting member (e.g., dolly, platform, pallet, etc.) so long as it is susceptible of moving, or being moved, while supporting a particular vehicle which will remain thereon for most of its stay at the facility; (b) a movable site most frequently, but not always, is located on a translatably movable transporting member of one kind or another. Such a transporting member may be (1) a carrier which receives a single vehicle and which has some degree of independence of movement, as provided for in subclasses 236+ below, or (2) a plural-vehicle-accommodating carrier (e.g a conveyor), certain ones of which are provided for in subclasses 242+ below, and see the definition of that subclass for certain arbitrary distinctions as to what constitutes a movable site therefor.

234	Vehicle assigned to particular supporting member (e.g., platform, dolly, cage, etc.) having some degree of independence either as to means, time or direction of movement:
	This subclass is indented under subclass 233.  Apparatus wherein a movable site comprises a member which receives one vehicle and forms the supporting element on which it rests during all or a predominant portion of its stay in or at the facility, and which member exhibits a degree of independence, as evidenced, for instance, by (a) being carried by a transporting device, or driven by an external means, but being separable or detachable from either one to follow another path or remain stationary, (b) having its own drive means and moving independently in a prescribed path or at random or remaining at rest, or (c) otherwise exhibiting a degree of independence of time or direction of movement. (1) Note. A separate supporting member of the kind contemplated by subclass 239 below, but intended for manual movement and therefore lacking the drive means required for that subclass (239), is found here.

235	Supporting member separable from endless, member-transporting carrier, or disengageable from endless drive means, and movable away therefrom for receiving, discharging or storing vehicle:
	This subclass is indented under subclass 234.  Apparatus wherein at least one supporting member is transported by an endless carrier, or is driven by an endless drive means, and is separable, or disengageable, respectively, therefrom for moving apart to a location at which it may receive or discharge a vehicle or to a fixed site where it and the vehicle will remain.

236	Plurality of supporting member moved in recirculating fashion by succession of driving devices:
	This subclass is indented under subclass 234.  Apparatus wherein a plurality of supporting members are moved in a single, fixed path, or in a plurality of paths which share a common origin and terminus, and wherein the means for moving the member comprises a plurality of successively arranged driving devices. (1) Note. The successively arranged driving devices may be powered from a single source.

237	Path of moving member describes generally rectangular loop:
	This subclass is indented under subclass 236.  Apparatus wherein the members move in a path which comprises a loop having two pair of opposite, parallel sides, one pair of which ordinarily is significantly greater in length than the other pair.

238	Successive devices each include endless, member-driving element (e.g., belt, cable, chain, etc.):
	This subclass is indented under subclass 237.  Apparatus wherein each of the successive driving devices includes an endless belt, cable, chain, etc., which engages and moves the member.

239	One or more separate supporting members and means to impart independent, linear or partly linear, movement thereto:
	This subclass is indented under subclass 234.  Apparatus comprising at least one separate member for receiving and supporting a single vehicle and means to move any or all such members in an independent manner and in a path which is, at least in part, linear in direction. (1) Note. The moving means may be a self-contained drive means, or it may be an external drive means; if there are a plurality of supporting members, an external drive means moves only one member at a time. (2) Note. See (1) Note of subclass 234 above.

240	Member moving from particular location to discharge and/or receive vehicle, and returning thereto:
	This subclass is indented under subclass 239.  Apparatus wherein a member is associated with a specific location in the facility and occupies that location when supporting a parked vehicle, the member leaving that location only to obtain a vehicle which is to be parked on it or to deliver such a vehicle.

241	With means to transfer vehicle to or from supporting member:
	This subclass is indented under subclass 234.  Apparatus wherein means is provided for moving a vehicle to or from a supporting member.

242	On driven, plural-site carrier initially receiving vehicle:
	This subclass is indented under subclass 233.  Apparatus wherein a movable site comprises any vehicle accommodating space on a driven carrier which is in excess of the space required for the carrier to transport a single vehicle, and wherein the carrier is the one to which the vehicle moves, or is moved, upon arriving at the facility. (1) Note. Vehicle accommodating platforms attached to an endless drive member, or mounted on a rotatable wheel, obviously constitute movable parking site. Less clear, however, is the case of, for instance, a two-, three-, four-car, vertically and/or horizontally driven, carrier; while such a carrier frequently is intended to transport only one vehicle at a time, and often does only that, the fact that it is common practice in the parking facility industry to utilize, when operating at or near the capacity of the facility, all available vehicle-accommodating space therefore necessitates treating any space in excess of that required for one vehicle as a movable site, since a corresponding number of vehicles may be left thereon for as long a period as desired.

243	With loading means, external to carrier, at facility entrance:
	This subclass is indented under subclass 242.  Apparatus wherein means which does not form a part of the structure of the initial carrier, is provided at or near the entrance to the facility for the purpose of moving (e.g., transferring) a vehicle to or from the initial carrier.
