DEFINITION

Classification: 198/703

(under subclass 701) Apparatus having particular means whereby the bucket may be loaded or unloaded more readily, including: means adapted to coact with the load in the bucket to assist in the loading or unloading operation; means to give the bucket a particular direction, motion, or path; by particularly designing or constructing the bucket for that purpose; or means controlling the flow of fluid to or from the bucket.

(1) Note. Patents having a mere end sheave over which the bucket passes to thereby invert the same so the load is caused to drop from the bucket are not included herein. However, patents providing sheave means in addition to the end sheave means to cause the bucket to travel a particular path which will facilitate a more complete or particularly directed load discharging or loading operation will be found in this and indented subclasses.

526+, for a conveyor system having a gravity conveyor section and including a moving (e.g., traveling) flow control means which is coordinated with a power-driven section (often of the bucket type) for the purpose of interrupting the flow of

material when no one of the conveying elements of the latter section is in a proper position to receive the flow.

702, for bucket conveyors for conveying liquid and having means whereby the liquid may be removed therefrom.

334+, for a moving, wheeled, load-transporting type vehicle (e.g., a bucket having track-engaging wheels for supporting it, and attached to an endless element for traction purposes) and a portable loading or unloading device therefor, the device being supported at least in part independently of the vehicle and traveling with the vehicle during the transfer of a load between the two; see especially subclass 336 thereunder for a suspendedly supported device, which is frequently the situation when the vehicle being loaded or unloaded is a car of an aerial tramway.
