Machine for peeling cereal grains by means of rubber rolls

Claim 1

A machine for peeling cereal grains, comprising: (a) first and second peeling rolls for peeling said cereal grains, said first peeling roll being fixedly mounted and positioned adjacent to said second peeling roll, said second peeling roll being moveably mounted to separate from and to form a gap with said first peeling roll; (b) a bin for containing a supply of said cereal grains having first and second opposing end walls, one of said end walls defining an accepting orifice for cereal grains and said other end wall defining a delivering orifice for cereal grains, said delivering orifice being positioned to directly deliver said cereal grains to said first and second peeling rolls, said bin being mounted to move along an axis substantially normal to the earth's surface; (c) a machine frame; (d) resilient means, fastened to said bin at one end and to said machine frame at another end, for providing a resilient force to said bin, said resilient force having a direction substantially parallel to said axis of said bin movement, said resilient means being calibrated to sustain said bin in an upper position along said axis of movement when said grain supply is at a minimum loading, said resilient means permitting said bin to be gradually displaced for many displacement positions depending upon the change in said grain supply that exceeds said minimum loading; (e) control means for controlling said machine; and (f) activating means coupled between said bin and said machine frame for initiating said control means, said activating means comprising a control actuating member having a motor, an adjusting member, and a first cooperating member, said activating means further comprising a control device having a second cooperating member and a control, said control actuating member being fixed in a position to cooperate with said control device by mutual contact of said first and second cooperating members, said cooperation changes said control from a first condition to a second condition, the mutual contact between said first and second cooperating members being initally realized when said bin is at a maximum displacement position along said axis of movement and said adjusting member is in a retracted position, the mutual contact of said first and second cooperating members being maintained by an urging force generated by said motor and delivered by said adjusting member as said bin is being displaced toward said upper position, said first condition of said control being resumed by the separation of said first and second cooperating members at a moment when said bin attains said upper position.
