Abstract
Abstract An animal processing machine including rib cutting apparatus constructed and arranged so as to optimize the rib portion cut from an animal side. The rib cutting apparatus includes a frame having a conveyor movable thereon and operable to convey an animal side to a rib cut knife. The animal side is urged against the conveyor, and the rib cut knife is mounted at an angle relative to the direction of conveyor travel, and is adapted to be tilted relative to the animal side so as to cut along a line corresponding to the brisket of the rib section. The knife is also twisted throughout its length, so as to provide an optimum amount of lean meat in the belly severed from the rib section. Additionally, the rib knife is initially oriented to sever the brisket or breast bone from the belly, so that the belly will be free from undesirable brisket bone. This twist function makes this initial orientation possible while providing a subsequent change in attitude relative to the animal side which increases the lean meat left on the portion which subsequently is converted to bacon.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
191 words
In an animal side processing machine having a frame and a conveyor movable with respect to said frame for conveying an animal side having a rib section therein remaining after previously cutting the loin therefrom, apparatus for cutting the remaining rib section from said animal side including the brisket thereof from said remaining animal side, said apparatus comprising: a. a rib knife support frame including a rib knife mounted thereon; b. means for tilting said rib knife support frame so that the end of the rib knife adjacent said brisket is raised by an amount whereby the rib knife follows the curve of said brisket and the corresponding ends of said ribs; c. means for twisting said rib knife along the longitudinal axis thereof so as to present a cutting edge adjacent one end of said knife at an attitude to cut beneath the brisket of said rib section and close thereto and subsequently to change its attitude concomitantly with the change in attitude of said tilting means so as to cause said rib knife to emerge out of the remaining animal side and cause lean meat to remain intact therein.
Claim 2
Dependent Claim
191 words
In an animal side processing machine having a frame and a conveyor movable with respect to said frame for conveying an animal side having a rib section therein remaining after previously cutting the loin therefrom, apparatus for cutting the remaining rib section from said animal side including the brisket thereof from said remaining animal side, said apparatus comprising: a. a rib knife support frame including a rib knife mounted thereon; b. means for tilting said rib knife support frame so that the end of the rib knife adjacent said brisket is raised by an amount whereby the rib knife follows the curve of said brisket and the corresponding ends of said ribs; c. means for twisting said rib knife along the longitudinal axis thereof so as to present a cutting edge adjacent one end of said knife at an attitude to cut beneath the brisket of said rib section and close thereto and subsequently to change its attitude concomitantly with the change in attitude of said tilting means so as to cause said rib knife to emerge out of the remaining animal side and cause lean meat to remain intact therein.
Claim 3
Dependent Claim
21 words
Apparatus according to claim 1 wherein means are provided for moving said rib knife support frame relative to said rib section.
Claim 4
Dependent Claim
47 words
Apparatus according to claim 1 wherein said rib cut knife is disposed at an angle relative to the direction of travel of said conveyor, and includes means for raising said rib cut knife from the animal side after the rib cut knife has cut a rib section.
Claim 5
Dependent Claim
19 words
Apparatus according to claim 1 wherein said rib knife twisting means comprises cylinders mounted on said rib support frame.
Claim 6
Dependent Claim
35 words
Apparatus according to claim 4 including control means responsive to the position of said animal side for actuating said twisting means thereby changing the orientation of said rib cut knife relative to said rib section.
Claim 7
Dependent Claim
34 words
Apparatus according to claim 1 including control means responsive to the location of said animal side for actuating said orientation changing means for properly moving said rib cut knife relative to said rib section.
Claim 8
Dependent Claim
44 words
Apparatus according to claim 1 wherein said conveyor means includes additional conveyor means mounted on said rib knife support frame for applying uniform traction on the top of said animal side for holding said animal side to the conveyor during the rib cutting operation.
