A bucket for a conveyor system including a conveyor belt and a wheel over which the belt passes, the bucket being attached to the belt and adapted to pick up material therein and discharge said material when that portion of the belt to which same is attached is passing over the wheel, said bucket comprising end Walls and abottom and a front wall defining the same, a cleaner for the bucket including a part extending into the bucket at the rear` thereof and having a relatively stiff cross-member rigidly supporting said part and attached transversely of the belt independently of the bucket, said bucket being secured to said belt in spaced relation longitudinally thereof relative to the said stili cross member, fastening devices for said cross member and bucket extending through said b-elt and clamping same to the belt and including bearing areas on the back side of the belt adapted to engage and cooperate with the cylindrical periphery of the wheel causing the cleaner and the bucket to assume circumferentially spaced tangential positions oneafter the other when the belt is passing over the wheel whereby to rock the cleaner and bucket one relative to the other for dislodging said material from the bucket.
9. A bucket for a conveyor system including a conveyor belt and a. wheel over which the belt passes, the bucket being attached to the belt and adapted to pick up material therein and discharge said material when that portion of the belt to which same is attached is passing over the Wheel, said bucket comprising a shell having an open back engaged against the belt and having a forward scooping edge for directing material into the shell, a cleaner member for the bucket including a plate-like part extending into the shell and of substantially the same width as the inside of the shell arranged to cover said' open back thereof, the cleaner member being secured to said belt and pivotally movable within the shell relative thereto between the back and front thereof, the bucket and cleaner member being sethe belt adapted to engage and cooperate with the cylindrical periphery of the wheel causing the cleaner member and bucket to assume circum-ferentially spaced tangential positions one periphery of the head wheel to rock the cleaner plate.
when thgbeltfis. passi-ng over-fthe lwv ee wherebyatorrock the cleaner member and orifrela-tive'to lthe' other for dislodging said material from the bucket.
10. A bucktfc'nstiutioii a's'd'e'scribed in claim the-.Salengro beek.. 0f thellellfhas a rigid plate extendingacross 4the sameg Aand, the said fastening devices extend through the said bend therein directed away from said rigid plate Y to clear the said bolt heads.
12. A bucket construction as described in claim 10 in which the fastening devices have bolt heads on the said plate, Vand the plate-like part of the cleaner member extends into the shell and overlies the said plate, and hasv perforations therein aligned with the bolt heads to permit the heads to enter therein and enable the said plate and plate-like part intimately to engage.
13. In combination with a conveyor belt passing over a head wheel, a self-cleaning bucket comprising a scoop shell anchored to said belt substantially along a line transverse of the belt so that the belt may bend relative to the shell ahead of and behind the line, a cleaning member having one end similarly anchored to the belt, albeit along a transverse line spaced from the rst-mentioned line and having a scraping free end disposed within the shell and capable of rocking relative thereto to disengage material from the interior thereof, the cleaning member and the shell both having parts rigidly connected respectively therewith and extending through said belt at the respective transverse lines and presenting planar surfaces onw the backside of the belt to the periphery of the wheel whereby the cleaning member and shell will be forced to assume positions tangential to the belt one after the other as the belt passes over the Wheel, thereby rocking one relative to the other to dislodge material in the shell.
14. A self-cleaning conveyor bucket for use in conveyor belt systems or the like having a head wheel over which the belt moves comprising a bucket shell having a rigid front, bottom and side walls, means rockably to anchor said bucket shell to said belt including a rigid member on the front of the belt and i'lxed` relative to said belt and bucket cooperating with the belt to hold the bucket in maximum load carrying position when the belt is moved linearly and second rigid member on the back of the belt, connected to the rst rigid member and conformed to cooperate with the periphery wof the head wheel to rock the bucket relative to the belt as the bucket passes over the head wheel, a cleaner within the bucket shell normally at the back thereof while the bucket is moving linearly and means to anchor the cleaner to the belt independent of and for vrocking movement relative to the bucket including a third rigid member on the front of the belt and iixed relative thereto linearly spaced from said first rigid member and having a fourth rigid member on the back of the belt connected thereto and also conformed to cooperate with the relative to the belt, said cleaner and belt rocking relative to one another during passage over the head wheel by virtue of the linear spacing between the first and third rigid members, whereby the cleaner will nieve from the back to the Yfront Number of the bucket te dislodge material ijn saidbucket. 377,917 JULES T.
