"Vintage Machinery" entry for Buffalo Pitts Co.
Description:
A. B. Stoughton - patent attorney

In grain thrashing and separating machines a shake-motion has been given to the straw belt or raddle but though this shake-motion is valuable in shaking out considerable grain that might otherwise be carried out with the straw and lost, yet it also shakes through straw and other stuff, which get into the fan-case and on the sieves, and prevent the free action of the machine. The object of my invention is to retain the advantages of the shake-motion to the raddle and to obviate the disadvantages arising, from it—viz., the clogging of the fan or of the sieves by the straw, which by the ordinary construction of separators also passed through the raddle; and the nature of my invention consists in combining with a straw belt or raddle, having a shake-motion, a rack or series of slats placed within the belt or raddle for-the purpose of preventing-the straw from falling through the belt and thence passing into the machine.
