Abstract
Disclosed are apparatus including novel workman's tool for removing hides, select cuts of meat, and generally carving away from animal carcasses relative large portions in cleanly cutaway non-comminuted condition. The apparatus, manually wieldable workman's tool, is deftly employable in a manner analagous to a conventional honed butcherman's knife; however, the knife-like shank of the tool includes tiny orifices emitting compressed air jets of sufficiently high intensity to carve the animal carcass. The emitted air jets to effect carving are made relatively free of solid particles and excessive moisture thereby maintaining the integrity of the air jets and the cleanly cutaway noncomminuted condition of the removed carcass portions.
Claims10
Apparatus for removing hides, select cuts of meat, and other relatively large portions of animal carcasses in cleanly-cut non-comminuted condition, said apparatus comprising:
- A. an air-compressor including an outlet-port for the emergence of the high pressure compressed air;
- B. an elongate flexible conduit extending downstream of the air-compressor for conducting the compressed air as an airstream, the flexible conduit having an inlet-end removably attached to the air-compressor outlet-port and having an outlet-end removably attached to an inlet-port of a portable workman's tool;
- C. said workman's tool comprising;
- i. a rearward handle wieldable by the workman;
- ii. an elongate shank attached to and extending forwardly of the handle, said shank at its peripheral edge being provided with at least one orifice having an orifice-diameter not exceeding one millimeter;
- iii. an airstream passageway extending from the inlet-port and at least partially extending along the shank interior and terminating at said at least one orifice, and
- iv. a manually actuatable tool-valve accessible to the handle and for controlling the airflow rate along said airstream passageway;
- D. filtering means located upstream of said workman's tool for filtering from the airstream solids having a particle size exceeding about one-half the orifice-diameter;
- and
- E. desiccating means located upstream of said workman's tool for desiccating the airstream before it enters the tool inlet-port.
Portable and deftly maneuverable workman's tool for sub-dividing animal carcasses by high intensity air jets impinging upon the animal carcass, said workman's tool comprising;
- i. a rearward handle deftly wieldable by the workman;
- ii. an elongate knife-like shank attached to the handle and extending forwardly thereof along a longitudinal tool-axis, said shank peripherally including an elongate lead-edge and an elongate trail-edge respectively provided with a plurality of regularly spaced orifices, said shank being internally provided with at least one longitudinally extending internal airstream passageway ultimately terminating at said peripheral orifices, the airstream passageway inside the shank including a lead-path and a trail-path, the lead-path extending to the orifices of the lead-edge and to the exclusion of the orifices of the trail-edge, the trail-path extending to the orifices of the trail-edge and to the exclusion of orifices of the lead-edge;
- iii. a manually actuatable tool-valve attached to the handle for selectively controlling airflow into the lead-path and trail-path of the shank internal passageway;
- and
- iv. an entry-tube attached to the tool-valve and to which the outlet-end of the elongate conduit might be removably attached, said entry-tube serving as an inlet-port for the introduction of compressed air into the workman's tool.
