Abstract
Abstract A stripper means for meat skinning machines is disclosed herein. The machine includes a driven toothed roll which is rotatably mounted on a frame means adjacent one end of a feed table. A pressure shoe means extends around a portion of the driven roll and has a skinning blade extending therefrom for severing the skin from the meat product as the product is moved thereby. The driven roll is provided with a plurality of spaced apart annular grooves formed in the peripheral surface thereof. A stripping shaft is mounted on the frame means below the driven roll and has a plurality of plastic stripping blades detachably mounted thereon in a spaced apart relationship. Each of the stripper blades has a concave upper end portion which is received in the grooves of the driven roll. The stripping blades strip the severed skin from the driven roll and will break if an extremely strong piece of skin becomes entangled in the driven roll. The ability of the stripping blades to fracture insures that the expensive driven roll will not be damaged by the stripping blades.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
224 words
In a device of the class described, a frame means, a driven roll rotatably mounted on said frame means, said driven roll having a plurality of spaced apart annular grooves formed therein which extend inwardly into the peripheral surface thereof, a pressure shoe means on said frame means extending around a portion of said driven roll, a skinning blade projecting from said pressure shoe means for severing the skin from the product being skinned, the severed skin being gripped by said driven roll and being passed between the periphery of said driven roll and said pressure shoe means, a stripper shaft on said frame means below said driven roll, a plurality of stripper blades detachably secured to said stripper shaft in a spaced apart relationship, each of said stripper blades having a concave end portion which is received in one of said grooves in said driven roll whereby said stripper blades will strip the severed skin from said driven roll, said stripper blades being comprised of a plastic material, said stripper shaft having a plurality of spaced apart annular grooves formed therein which extend inwardly into the peripheral surface thereof which are aligned with the grooves in said driven roll, said stripper blades each having a substantially semi-circular opening formed therein which is detachably received by one of the grooves in said stripper shaft.
Claim 2
Dependent Claim
224 words
In a device of the class described, a frame means, a driven roll rotatably mounted on said frame means, said driven roll having a plurality of spaced apart annular grooves formed therein which extend inwardly into the peripheral surface thereof, a pressure shoe means on said frame means extending around a portion of said driven roll, a skinning blade projecting from said pressure shoe means for severing the skin from the product being skinned, the severed skin being gripped by said driven roll and being passed between the periphery of said driven roll and said pressure shoe means, a stripper shaft on said frame means below said driven roll, a plurality of stripper blades detachably secured to said stripper shaft in a spaced apart relationship, each of said stripper blades having a concave end portion which is received in one of said grooves in said driven roll whereby said stripper blades will strip the severed skin from said driven roll, said stripper blades being comprised of a plastic material, said stripper shaft having a plurality of spaced apart annular grooves formed therein which extend inwardly into the peripheral surface thereof which are aligned with the grooves in said driven roll, said stripper blades each having a substantially semi-circular opening formed therein which is detachably received by one of the grooves in said stripper shaft.
Claim 3
Dependent Claim
195 words
In a device of the class described, a frame means, a driven roll rotatably mounted on said frame means, said driven roll having a plurality of spaced apart annular grooves formed therein which extend inwardly into the peripheral surface thereof, a pressure shoe means on said frame means extending around a portion of said driven roll, a skinning blade projecting from said pressure shoe means for severing the skin from the product being skinned, the severed skin being gripped by said driven roll and being passed between the peripheries of said driven roll and said pressure shoe means, a stripper shaft on said frame means below said driven rOll, a plurality of stripper blades detachably secured to said stripper shaft in a spaced apart relationship, each of said stripper blades having a concave end portion which is received in one of said grooves in said driven roll whereby said stripper blades will strip the severed skin from said driven roll, each of said stripper blades being individually detachably secured to said stripper shaft so that any of said stripper blades may be removed from said stripper shaft without removing the other of said stripper blades.
Claim 4
Dependent Claim
195 words
In a device of the class described, a frame means, a driven roll rotatably mounted on said frame means, said driven roll having a plurality of spaced apart annular grooves formed therein which extend inwardly into the peripheral surface thereof, a pressure shoe means on said frame means extending around a portion of said driven roll, a skinning blade projecting from said pressure shoe means for severing the skin from the product being skinned, the severed skin being gripped by said driven roll and being passed between the peripheries of said driven roll and said pressure shoe means, a stripper shaft on said frame means below said driven rOll, a plurality of stripper blades detachably secured to said stripper shaft in a spaced apart relationship, each of said stripper blades having a concave end portion which is received in one of said grooves in said driven roll whereby said stripper blades will strip the severed skin from said driven roll, each of said stripper blades being individually detachably secured to said stripper shaft so that any of said stripper blades may be removed from said stripper shaft without removing the other of said stripper blades.
Claim 5
Dependent Claim
24 words
The device of claim 2 wherein said stripper blades are comprised of a thin plastic material which is fracturable upon encountering said driven roll.
Claim 6
Dependent Claim
37 words
The device of claim 1 wherein said substantially semi-circular opening in each of said stripper blades is greater than 180* so that more than one-half of the circumference of said groove in said stripper shaft is embraced.
Claim 7
Dependent Claim
22 words
