Blade holder for meat trimming knife

Claim 2

A blade holder construction for a meat-cutting tool of the type having a power-driven handle assembly with a concave arcuate surface at one end formed with two tapped holes therein and having a drive gear rotatably supported in the handle assembly for driving a gear toothed ring blade adapted to be rotatably supported by the blade holder construction, said blade holder construction including: (a) a split annular-shaped ring; (b) an interior, annular groove formed in the ring for rotatably mounting a complementary-shaped cutting blade therein; (c) inwardly projecting arcuate flange means formed integrally with the ring; (d) exterior arcuate groove means formed in the ring for engagement with alignment keys mounted on the concave arcuate surface of the power-driven handle; (e) an arcuate-shaped plate formed with a drive gear-receiving recess and a pair of holes, said holes being adapted to align with the tapped holes of the power-driven handle for receiving a pair of screws therethrough for removably attaching the plate on the concave surface of said handle, and said plate having a smooth concave inner surface and a generally smooth convex outer surface; in which said outer surface is formed with an end portion having a larger radius of curvature than an adjacent intermediate portion with said larger end portion providing a contact pressure zone engageable with the arcuate end surface of the handle when the blade holder is attached to said handle; and (f) arcuate groove means formed in the plate, said plate groove means being complementary to and removably engaged with the inwardly extending arcuate flange means of the ring to removably mount said ring on the plate.

Claim 3

The construction defined in claim 1 in which the arucate flange means and arcuate groove means formed on the ring are formed by a T-shaped, cross-sectional arcuate upstanding portion of the ring.

Claim 4

The construction defined in claim 1 in which an arcuate portion of the plate extends beyond the ring-receiving groove means a predetermined distance in a direction away from the gear-receiving recess to provide a cover for gear teeth formed on the cutting blade.

Claim 5

A blade holder construction for a meat-cutting tools of the type having a power-driven handle assembly with a concave arcuate surface at one end formed with two tapped holes therein and having a drive gear rotatably supported in the handle assembly for driving a gear tooth ring blade adapted to be rotatably supported by the blade holder construction, said blade holder construction including: (a) an annular-shaped metal ring split at one point and having exterior arcuate grooves formed on both sides of the split to provide circumferentially extending alignment grooves for engagement with alignment members of a power driven handle, said metal ring further including inwardly extending arcuate-shaped flanges formed on each side of the split, said arcuate shaped flanges being of a length sufficient to provide an anti debri cover for gear teeth formed along an edge of a cutting blade when the cutting blade gear teeth are adjacent the mounting plate, said metal ring further including a split annular shaped, top wall, a split annular shaped side wall and a split annular shaped radially inwardly extending ledge spaced from said top wall with said walls and ledge forming a cutting blade mounting groove, (b) an arcuate-shaped blade holder mounting plate having formed thereon a semicircular recess for accommodating some gear means, and having a pair of spaced holes located at some point, each equidistant from said semicircular recess, said spaced openings designed for receiving attachment screws for releasably securing said mounting plate and split metal ring onto a power driven handle, said blade holder further including inner and outer arcuate surfaces, in which an arcuate grove is formed in the outer arcuate surface and is located adjacent and extends along an edge of said mounting plate, said arcuate groove being complementary to the arcuate shaped flanges on said metal ring thereby permitting said metal ring to be removably attached to said blade holder mounting plate.

Claim 6

A blade holder construction for a meat-cutting tools of the type having a power-driven handle assembly with a concave arcuate surface at one end formed with two tapped holes therein and having a drive gear rotatably supported in the handle assembly for driving a gear tooth ring blade adapted to be rotatably supported by the blade holder construction, said blade holder construction including: (a) an annular-shaped metal ring split at one point and having exterior arcuate grooves formed on both sides of the split to provide circumferentially extending alignment grooves for engagement with alignment members of a power driven handle, said metal ring further including inwardly extending arcuate-shaped flanges formed on each side of the split, said arcuate shaped flanges being of a length sufficient to provide an anti debri cover for gear teeth formed along an edge of a cutting blade when the cutting blade gear teeth are adjacent the mounting plate, said metal ring further including a split annular shaped, top wall, a split annular shaped side wall and a split annular shaped radially inwardly extending ledge spaced from said top wall with said walls and ledge forming a cutting blade mounting groove, (b) an arcuate-shaped blade holder mounting plate having formed thereon a semicircular recess for accommodating some gear means, and having a pair of spaced holes located at some point, each equidistant from said semicircular recess, said spaced openings designed for receiving attachment screws for releasably securing said mounting plate and split metal ring onto a power driven handle, said blade holder further including inner and outer arcuate surfaces, in which an arcuate grove is formed in the outer arcuate surface and is located adjacent and extends along an edge of said mounting plate, said arcuate groove being complementary to the arcuate shaped flanges on said metal ring thereby permitting said metal ring to be removably attached to said blade holder mounting plate.
