Francis King, of Ithaca, N. Y.; has token measures to secure a patent for an improved Grain Separator. In this improvement the grain, before passing into the riddle, is made to fall through an open concave receptacle, composed of thin strips of metal or other material, so as to allow of its more perfect separation before its escape into the former. In the central part of this concave receptacle the separator is mada to. revolve, and the slots and endless belts are so connected together that there may be no liability of their becoming disconnected when the mechanism is in operation.
