Abstract
Abstract A method and apparatus for deboning chicken is disclosed which includes providing a novel chicken deboning horn B,B' which is rigidly mounted to a stabilized table top conveyor A so that a chicken carcass P may be rigidly supported and conveyed for carving of the meat away from the bones in a mass production system. The deboning horn preferably includes a smooth horn 40 having a contoured surface 42 inclined upwardly to a reduced upper portion 40b which enters an internal cavity 43 of the carcass P. Thus, inserted, the horn contour bears against and engages spaced portions in the cavity to hold it rigid and upright while enabling rotation of the carcass for selective carving. The horn contour accepts a wide range of carcass cavity sizes owing to its cone-shaped contour. Alternate chicken retaining supports 50, 62 support poultry portions 58, 72 separately for deboning. At least the upper run of conveyor A is stabilized by means of longitudinal guide rails 12 having guide slots 12a in which opposing ends 20a, 20b of the conveyor links 20 are effectively retained.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
172 words
Apparatus for deboning chicken comprising: an elongated frame; an elongated conveyor carried by said frame; means stabilizing said conveyor against movement in vertical and transverse directions with respect to the direction of conveyance providing a generally rigid moving platform; a plurality of chicken retaining means carried by said conveyor in spaced relation along the length of said conveyor for supporting chicken carcasses; said chicken retaining means including cone-shaped means with a substantially smooth surface thereon receivable in an internal cavity of said chicken carcass engaging portions of said chicken carcass within said internal cavity rigidly supporting said chicken carcass in a generally upright vertical position for permitting deboning; means rigidly mounting said retaining means on said conveyor so that said conveyor and said retaining means, are unitarily rigid and said chicken carcasses are firmly held in said upright position as they are moved along the run of said conveyor; whereby persons standing along said conveyor can readily debone said chickens as said chickens are moved along the length of said elongated frame.
Claim 2
Dependent Claim
172 words
Apparatus for deboning chicken comprising: an elongated frame; an elongated conveyor carried by said frame; means stabilizing said conveyor against movement in vertical and transverse directions with respect to the direction of conveyance providing a generally rigid moving platform; a plurality of chicken retaining means carried by said conveyor in spaced relation along the length of said conveyor for supporting chicken carcasses; said chicken retaining means including cone-shaped means with a substantially smooth surface thereon receivable in an internal cavity of said chicken carcass engaging portions of said chicken carcass within said internal cavity rigidly supporting said chicken carcass in a generally upright vertical position for permitting deboning; means rigidly mounting said retaining means on said conveyor so that said conveyor and said retaining means, are unitarily rigid and said chicken carcasses are firmly held in said upright position as they are moved along the run of said conveyor; whereby persons standing along said conveyor can readily debone said chickens as said chickens are moved along the length of said elongated frame.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein said contoured means is contoured to engage upper and lower portions of said internal cavity of said carcass at spaced portions thereof to support same rigidly thereon.
Claim 4
Dependent Claim
34 words
The apparatus of claim 1 wherein said contoured means is contoured to accommodate a wide variety of poultry carcass cavity sizes engaging portions of different size cavities to support same in said rigid position.
Claim 5
Dependent Claim
42 words
The apparatus of claim 1 wherein said conveyor has transversely spanning link means stabilized in said movement by longitudinally extending guide means limiting movement of opposing ends of said link means in vertical and transverse directions relative to the direction of conveyance.
Claim 6
Dependent Claim
40 words
The apparatus of claim 4 wherein said guide means includes longitudinal slots extending substantially over a top run of said conveyor, said opposing ends of said link means being retained and guided by said slots securing same against said movement.
Claim 7
Dependent Claim
46 words
The apparatus of claim 1 including poultry removal means carried adjacent an end of said conveyor in the direction of conveyance for engaging said chicken carcass after said retaining means turns past a vertical at said end facilitating removal of the same from said retaining means.
Claim 8
Dependent Claim
27 words
The apparatus of claim 1 including a second conveyor carried by said frame adjacent said first mentioned conveyor conveying said poultry meat after separation from the carcass.
Claim 9
Dependent Claim
120 words
Poultry deboning apparatus comprising: an elongated conveyor; poultry retaining means carried in spaced relation on said elongated conveyor; mounting means rigidly attaching said retaining means to said conveyor; said poultry retaining means including a deboning horn having a contoured support surface means inclined toward an upper portion thereof; said horn having prong means adjacent said upper portion diverging outwardly for contacting a portion of said poultry carcass while a remainder of said carcass portion is supported on said contoured surface; and whereby the poultry may be firmly supported and retained for carving to facilitate separation of the poultry meat from the carcass by people positioned along the run of said conveyor as said poultry is moved by said elongated conveyor.
Claim 10
Dependent Claim
120 words
Poultry deboning apparatus comprising: an elongated conveyor; poultry retaining means carried in spaced relation on said elongated conveyor; mounting means rigidly attaching said retaining means to said conveyor; said poultry retaining means including a deboning horn having a contoured support surface means inclined toward an upper portion thereof; said horn having prong means adjacent said upper portion diverging outwardly for contacting a portion of said poultry carcass while a remainder of said carcass portion is supported on said contoured surface; and whereby the poultry may be firmly supported and retained for carving to facilitate separation of the poultry meat from the carcass by people positioned along the run of said conveyor as said poultry is moved by said elongated conveyor.
