This inventionrelates to certain'new and useful'improvements in accumulator bins for a grain cleaning machines and the'like; p

a The primary object of the invention is to I? provide an accumulator bin for grain cleaningmachines wherein the grain dropped into aihopper andconveyed to a pointfor discharge into a machine is controlled in its flow v to the machine-with an accumulator bin to 1 receive excess graindelivered to the machine for returnto the hopper," permitting the regulation of feed at themachine rather than at the elevator boot and-permitting an operator to'perform other duties while the grain col- ,lected in the accumulator bin is returned to V I the hopper for re-delivery to the machine' by graincleaning machine, it is of course adapt- 'ed to' 'iis'e with other typesjof machines handling granular materiahi "clippers, separators, etc.
