Abstract
Abstract This disclosure relates to a bone holding mechanism for supporting a bone by one end thereof while meat stripping operations are performed. The mechanism comprises a bone encircling and holding member having a suspended fixed jaw and a piston actuated movable jaw mounted therein. Upon insertion of a bone, the piston operated jaw is moved toward the fixed jaw to hold the bone securely from rotational and longitudinal movement while meat stripping operations are being performed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
226 words
A bone holding apparatus comprising: a base member; a pair of jaws mounted on said base mEmber; gripping means on each of said jaws adapted to hold said one end of a bone placed therebetween; one jaw of said pair being movable toward and away from the other jaw of said pair for forcing a bone against the gripping means of said other jaw of said pair thereby clamping said bone between said jaws; said other jaw of said pair being of a shape to encompass at least a portion of a bone held therein and being freely pivotally mounted on said base member relative to said one jaw of said pair, the pivotal mounting thereof being about an axis extending transverse to the direction of movement of said one jaw and through an area located between the two jaws permitting said other jaw to pivot to different positions locating the gripping means of said other jaw at differently spaced distances from a plane on which said axis is located and which extends generally in the same direction as the medial axis of said bones to be held therein, whereby said jaws automatically adjust to bones of varying sizes; and driven actuator means for moving and forcing said one jaw toward said other jaw to thereby hold and restrain said bone from longitudinal and rotational movement.
Claim 2
Dependent Claim
226 words
A bone holding apparatus comprising: a base member; a pair of jaws mounted on said base mEmber; gripping means on each of said jaws adapted to hold said one end of a bone placed therebetween; one jaw of said pair being movable toward and away from the other jaw of said pair for forcing a bone against the gripping means of said other jaw of said pair thereby clamping said bone between said jaws; said other jaw of said pair being of a shape to encompass at least a portion of a bone held therein and being freely pivotally mounted on said base member relative to said one jaw of said pair, the pivotal mounting thereof being about an axis extending transverse to the direction of movement of said one jaw and through an area located between the two jaws permitting said other jaw to pivot to different positions locating the gripping means of said other jaw at differently spaced distances from a plane on which said axis is located and which extends generally in the same direction as the medial axis of said bones to be held therein, whereby said jaws automatically adjust to bones of varying sizes; and driven actuator means for moving and forcing said one jaw toward said other jaw to thereby hold and restrain said bone from longitudinal and rotational movement.
Claim 3
Dependent Claim
27 words
A bone holding apparatus as described in claim 1 wherein said other jaw forms an arc and encompasses at least a portion of a bone held therein.
Claim 4
Dependent Claim
44 words
The bone holding apparatus as described in claim 1 wherein said movable jaw is positioned away from and upwardly with respect to said fixed jaw when in an open position whereby said one end of a bone may be inserted laterally into said holder.
Claim 5
Dependent Claim
39 words
The bone holding structure as described in claim 1 wherein said actuator means comprises: a cylinder formed within said base member; and a piston movable within said cylinder, said movable jaw operably connected to said piston and movable therewith.
Claim 6
Dependent Claim
42 words
The bone holding structure as described in claim 4 and further including a connecting rod connected at one end to said piston and movable therewith; and a linking member, said linking member connected to said piston rod and to said movable jaw.
Claim 7
Dependent Claim
47 words
The bone holding structures as described in claim 4 wherein said piston in said cylinder forms two independent chambers within said cylinder; and fluid pressure ports connected to said chambers, said piston movable within said cylinder in response to the presence of fluid pressure in said chambers.
Claim 8
Dependent Claim
67 words
The bone holding apparatus as described in claim 4 wherein said cylinder has an upper and a lower chamber, each of said chambers being selectively connected to a source of fluid pressure; a cylinder head fixed at the upper chamber of said cylinder and having a depending central portion extending into said upper chamber to define the upper limit of travel of said piston within said cylinder.
Claim 9
Dependent Claim
21 words
A bone holding apparatus as described in claim 1 wherein said fixed jaw has a plurality of bone-engaging members fixed thereon.
Claim 10
Independent Claim
115 words
An apparatus for holding a bone in an automatic deboning machine comprising: a base member; a pair of jaws mounted on said base member, one jaw of said pair being movable toward and away from the other jaw of said pair for forcing a bone against the other jaw of said pair thereby clamping said bone between said jaws, said movable jaw pivotally attached to said base member; a piston chamber formed in said base member, said chamber having fluid pressure inlet and outlet ports communicating therewith; a piston in said chamber, said piston being movable in response to fluid pressure applied through said ports; and linkage means connecting said piston to said movable jaw.
Claim 11
Independent Claim
115 words
An apparatus for holding a bone in an automatic deboning machine comprising: a base member; a pair of jaws mounted on said base member, one jaw of said pair being movable toward and away from the other jaw of said pair for forcing a bone against the other jaw of said pair thereby clamping said bone between said jaws, said movable jaw pivotally attached to said base member; a piston chamber formed in said base member, said chamber having fluid pressure inlet and outlet ports communicating therewith; a piston in said chamber, said piston being movable in response to fluid pressure applied through said ports; and linkage means connecting said piston to said movable jaw.
Claim 12
Dependent Claim
34 words
A bone holding apparatus as defined in claim 9 and further including serrations on at least one of said jaws to engage an end of said bone as said jaws move toward each other.
Claim 13
Dependent Claim
27 words
A bone holding apparatus as described in claim 10 wherein said other jaw forms an arc and encompasses at least a portion of a bone held therein.
Claim 14
Dependent Claim
20 words
A bone holding apparatus as described in claim 11 wherein said other jaw is pivotally mounted on said base member.
