US 5,311,664 A · Power skinning knife with unidirectional rotating blade

Abstract

A power skinning knife having a single substantially disc shaped blade driven in continuous unidirectional rotary motion with a pair of blade shields on opposite sides of the blade covering most of the blade and exposing only a limited depth arcuate cutting region of the blade between the perimeter of the shield and the cutting edge. The blade is driven by a pneumatic motor that is geared to turn first and second toothed pulleys connected by a toothed belt. The blade may be circular or lobed and mounted concentrically or offset to provide either a smooth or pulsing cutting action. The tool may also include a wiping element which removes debris from the blade edge before it enters the tool housing and a steeling element which can be actuated by the operator's thumb while the tool is being used to sharpen the blade.

Dependent claims

A power skinning knife comprising:

a handle;
a single substantially disk shaped blade having a center offset from an axis of cutting rotation, the blade being mounted for offset rotation about the axis of cutting rotation;
a non-rotating blade shield covering a central region of the blade and exposing a limited depth arcuate cutting region of the blade between the perimeter of the shield and the cutting edge of the blade, the depth of the arcuate cutting region varying as the offset blade rotates;
a motor mounted in the handle;
and
a drive mechanism connected between the blade and the motor for rotating the blade in a continuous unidirectional rotary motion about the axis of cutting rotation.
