Abstract
Abstract A series of downward tiltable trays are connected end-to-end to form a conveyor traveling over the feeders leading to the machines to which the load traveling on the trays is to be distributed, while means are provided to tilt the trays toward the feeders in order to transfer their load upon them, while a movement equal and contrary to that of the trays is imparted to the tray surface during said transfer.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
A conveyor for the distribution of the output of a station in a production line to units of a subsequent station, said conveyor comprising a plurality of trays to carry said output, interconnected in an end-to-end relationship and positioned above the feeders of the subsequent station, means to impart to said interconnected trays a continuous motion, means, positioned correspondingly to said feeders, to tilt the trays toward said feeders in order to discharge their load upon the latter, means to restore said trays to their untilted condition, said trays comprising a rigid plate means having ears at its forward end; a cylinder placed intermediate said ears; a gear fastened to one end of said cylinder, coaxially with it; a shaft passed through holes in said ears and said cylinder; and an endless belt looped tight around said cylinder and the trailing end of said plate to form the load carrying surface of said tray.
Claim 2
Dependent Claim
154 words
A conveyor for the distribution of the output of a station in a production line to units of a subsequent station, said conveyor comprising a plurality of trays to carry said output, interconnected in an end-to-end relationship and positioned above the feeders of the subsequent station, means to impart to said interconnected trays a continuous motion, means, positioned correspondingly to said feeders, to tilt the trays toward said feeders in order to discharge their load upon the latter, means to restore said trays to their untilted condition, said trays comprising a rigid plate means having ears at its forward end; a cylinder placed intermediate said ears; a gear fastened to one end of said cylinder, coaxially with it; a shaft passed through holes in said ears and said cylinder; and an endless belt looped tight around said cylinder and the trailing end of said plate to form the load carrying surface of said tray.
Claim 3
Dependent Claim
46 words
A conveyor as per claim 1, wherein the trays are interconnected by two parallel endless chains running between sprocket wheels, each end of the shaft of each tray forming the link pin of the chains at the point of connection between said shaft and said chains.
Claim 4
Dependent Claim
18 words
A conveyor according to claim 1, wherein the trays comprise laterally projecting followers placed adjacently their trailing portion.
Claim 5
Dependent Claim
17 words
A conveyor according to claim 3, comprising guide means for said followers running parallel to said chains.
Claim 6
Dependent Claim
81 words
A conveyor according to claim 4, wherein the means to tilt the trays toward the feed conveyors of the subsequent stations are flap means provided in said guides and positioned in the paths of said followers and which, from a horizontal position permitting the passage of said tray over them, are downwardly tiltable to a position inclined toward said feed conveyors thereby lowering the trailing portion of said trays upon said feed conveyor surface to transfer their load upon the latter.
Claim 7
Dependent Claim
41 words
A conveyor according to claim 4, wherein the means to restore said trays to their untilted position are upward inclined plates leading from the feed conveyor surface back to said guide means, and positioned in the path of the tray followers.
Claim 8
Dependent Claim
53 words
A conveyor according to claim 1, wherein, correspondingly to the feed conveyors, racks are provided to engage said gears during the tilt of the trays, thereby imparting to the belt forming the tray surface a motion whose speed is equal but whose direction is contrary to the speed and direction of the trays.
