Abstract: A separating device for separating first and second bones or cartilage parts comprises a first structure with a first elongated member and a stationary engaging member at one end of the first elongated member; a second structure with a second elongated member and a separation member at one end of the second elongated member; a moving device for moving the second structure relative to the stationary engaging member from a contracted position to a closed position. An angular position of the first and the second structures are adjusted, so the subsequent movement of the separation member towards the closing position intersects a separation area between the first and second bones or cartilage parts causing an immediate separation between the first and second bones or cartilage parts.

Abstract: An apparatus for supporting and maneuvering an animal carcass includes a frame and a carcass holding device connected with the frame. The carcass holding device includes a gear assembly, a pair of support arms, and a pair of plates connected with the support arms. The support arms each have a first end connected with the gear assembly and a second end with which the plates are connected. The gear assembly is operable to displace the plates between a retracted position in which the plates may be inserted into an animal carcass rib cage, and an expanded position wherein the plates engage the rib cage to secure the animal carcass for butchering. Preferably, the frame is adjustable to provide linear displacement and rotation of the carcass holding device.

The helical members direct the lubricant away from an end of the flexshaft assembly that the helix of wires tends to direct the lubricant toward.

Abstract: A rotary knife comprising, an annular blade having a central axis, a blade supporting head assembly supporting the blade for rotation about the axis, a manually grippable handle assembly connected to the head assembly, and a flex shaft drive transmission for driving the blade about the axis. The handle assembly comprises a core, a hand grip surrounding the core, and a connector unit that secures the hand grip to the core. The core has a first end region rigidly fixed with respect to the head assembly and a second end region spaced from the bead assembly. The core defines a drive transmission guiding channel leading toward the blade. The hand grip has a first end region proximal the blade support assembly and a second end region proximal the second core end region. The connector detachably secures the hand grip in fixed relationship with the core. The connector engages the second end regions and is detachable for enabling hand grip removal and replacement.

Abstract: The subject apparatus includes three implements which complement each other in the removal of skin portions, abdominal lining portions and bone portions from a fish steak. One implement is tongs having a plurality of tips which are pressed into the steak, surrounding the central bone portions, allowing their removal by pressing the tips toward each other to grasp and then remove those portions. A second implement is a blade on a handle. The blade is essentially perpendicular to the handle, sharp on both edges and its broad surfaces are perpendicular to the long axis of the handle. The blade is passed between the flesh portions of the steak and the skin portion and the abdominal cavity lining portion (if any) to separate and allow removal of those portions. A third implement is a tweezers specially adapted to grasping the ends of bones which extend through the steak perpendicular to its broad, flat surfaces and to grasping and removing the free skin and lining portions.
