Patent No. 2641357A: Device For Cleaning Out The Bottoms Of Grain Elevators

June 9, 2015 By Jay Brooks

patent-logo
Today in 1953, US Patent 2641357 A was issued, an invention of Lester Jones (presumably not the economist with the NBWA), assigned to Pabst Brewing Co., for his “Device for Cleaning Out the Bottoms of Grain Elevators.” There’s no Abstract, although in the description it states that the “invention appertains to the handling of grain, and more particularly to a novel cleaning attachment for a grain elevator.”

In the handling of grain by bucket elevators, there is a clearance between the bottom wall or pan of the elevator housing and the elevator buckets. Consequently, a certain small portion of grain lies in an inactive state on this bottom wall or pan. If this grain is not periodically removed, there is danger that the same will spoil or become infected and contaminate the grain passing through the elevator. This condition is recognized, and provisions have been made to remove the inactive grain, but in all constructions with which I am familiar, it is necessary to shut down the elevator to effect the cleaning thereof. Consequently, there is a tendency to put off the cleaning of the elevator as long as possible.
