Abstract
Abstract This disclosure relates to a novel device for feeding material to a processing machine including means for defining a path of travel for the material to be treated between upstream and downstream portions of the device, means at the downstream portion for feeding the material from the device, means for shaking the material as it moves along the path between the upstream and downstream portions thereof, and means for controlling the speed of operation of the shaking means proportionately to and in dependence upon the speed of operation of the feeding means, preferably the controlling means are mechanical transmission means between the shaking means and the feeding means in the form of sprocket and drive means, and the shaking means includes a wall mounted for swinging motion with respect to and in part defining the path of travel for the material.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
The combination of a feeding device and a processing machine comprising first means defining a first path of travel for material between input and output ends of said feeding device, second means defining a second path of travel for material from said feeding device output end to an input end of said processing machine, conveying means at said processing machine input end for feeding material into said processing machine, first motor means for driving said conveying means, means beyond said processing machine input end for processing material therein, means for shaking said material as it moves along said first path, second motor means for driving said shaking means, means for directly controlling the speed of operation of said shaking means proportionally to the speed of operation of said conveying means, and said controlling means include electrical regulating means coupled between said first and second motor means for increasing and decreasing the speed of said second motor means in response to respective increasing and decreasing speed of said first motor means.
Claim 2
Dependent Claim
170 words
The combination of a feeding device and a processing machine comprising first means defining a first path of travel for material between input and output ends of said feeding device, second means defining a second path of travel for material from said feeding device output end to an input end of said processing machine, conveying means at said processing machine input end for feeding material into said processing machine, first motor means for driving said conveying means, means beyond said processing machine input end for processing material therein, means for shaking said material as it moves along said first path, second motor means for driving said shaking means, means for directly controlling the speed of operation of said shaking means proportionally to the speed of operation of said conveying means, and said controlling means include electrical regulating means coupled between said first and second motor means for increasing and decreasing the speed of said second motor means in response to respective increasing and decreasing speed of said first motor means.
Claim 3
Dependent Claim
24 words
The device as defined in claim 1 wherein said controlling means include mechanical transmission means between said shaking means and said second motor means.
Claim 4
Dependent Claim
40 words
The device as defined in claim 2 wherein said mechanical transmission means includes a cam means for imparting motion to said shaking means, and drive means coupled between said second motor means and said cam means for rotating the latter.
