Abstract

A skinning machines having a gripping roll, a skinning blade, a power unit for rotating the gripping roll, and a safety circuit responsive to manual contact of the machine operator with danger zone of the skinning machine. A clutch is provided to the skinning machine is operatively connected to the gripping roll and the power source for the gripping roll. A brake is connected to the safety circuit and the gripping roll. The clutch is normally operative, and the brake is normally inoperative, whereby the brake will stop the rotation of the gripping roll when the safety circuit is activated to overcome the operative condition of the clutch. The brake includes a coiled spring that tightens on a hub connected to the gripping roll when the safety circuit is actuated. The safety circuit includes a solenoid device that releases the spring to tighten on the hub when the safety circuit is actuated.

Claims

1. An improvement in a skinning machine having a frame, a gripping roll, a skinning blade, a power means for rotating said gripping roll, and a safety circuit responsive to manual contact of the machine operator with a danger zone on said skinning machine, the improvement comprising;

a clutch means operatively connecting said gripping roll and said power means,

a brake means connecting said safety circuit and said gripping roll,

said clutch means being normally operative, and said brake means being normally inoperative, whereby said brake means will stop the rotation of said gripping roll when said safety circuit is activated to overcome the operative condition of said clutch means without disengaging the clutch means.

2. The apparatus of claim 1 wherein said brake means includes a coiled spring that tightens on a hub means connected to said gripping roll when said safety circuit is activated.

3. The apparatus of claim 2 wherein a solenoid means comprises a part of said safety circuit, said solenoid means being attached to said coiled spring to release said spring to allow tightening of said spring when said safety circuit is activated.
