Abstract
Abstract An improved blade holder construction for rotatably mounting a circular-shaped meat-cutting blade on a handle having power drive means connected thereto. A metal ring is formed with an interior annular blade-receiving groove, and is split at one point on its periphery. A pair of axially extending, upstanding metal flanges are founded on opposite sides of the split integral with the ring. A pair of plastic mounting lugs are molded about the upstanding flanges and extend circumferentially along adjacent portions of the ring. A semicircular recess is formed in each of the lugs to provide a gear chamber for receiving a gear which drivingly engages the blade mounted in the ring groove. Arcuate portions of the plastic lugs are spaced axially from the top surface of the ring to form a pair of alignment grooves. A pair of oval-shaped holes are formed in the plastic lugs for adjustably mounting the holder on the handle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
A blade holder construction for a meat-cutting tool including: (a) an annular-shaped metal ring split at one point on its periphery; (b) an interior, annular groove formed in the ring for rotatably mounting a complementary shaped cutting blade therein; (c) a pair of axially extending arcuate flanges formed integrally with the metal ring and located on opposite sides of the split; (d) a pair of plastic arcuate-shaped lugs molded on the ring flanges and projecting upwardly from and circumferentially along a portion of the ring on both sides of the split for attaching the blade holder to a power-driven handle; (e) a semicircular recess formed in each of the plastic lugs in juxtaposition to each other to form a generally circular-shaped gear-receiving recess; and (f) a radially extending mounting hole formed in each of the lugs adapted to receive attachment screws therein.
Claim 2
Dependent Claim
142 words
A blade holder construction for a meat-cutting tool including: (a) an annular-shaped metal ring split at one point on its periphery; (b) an interior, annular groove formed in the ring for rotatably mounting a complementary shaped cutting blade therein; (c) a pair of axially extending arcuate flanges formed integrally with the metal ring and located on opposite sides of the split; (d) a pair of plastic arcuate-shaped lugs molded on the ring flanges and projecting upwardly from and circumferentially along a portion of the ring on both sides of the split for attaching the blade holder to a power-driven handle; (e) a semicircular recess formed in each of the plastic lugs in juxtaposition to each other to form a generally circular-shaped gear-receiving recess; and (f) a radially extending mounting hole formed in each of the lugs adapted to receive attachment screws therein.
Claim 3
Dependent Claim
29 words
The blade holder construction defined in claim 1 in which the mounting holes have an oval shape to provide for adjustment mounting of the holder on a power-drive handle.
Claim 4
Dependent Claim
23 words
The blade holder construction defined in claim 1 in which the arcuate ring flanges each extend throughout an arcuate length of approximately 55°.
Claim 5
Dependent Claim
43 words
The blade holder construction defined in claim 1 in which opening means are formed in each of the arcuate ring flanges; and in which a slug of plastic extends through said flange opening means and is formed integrally with the plastic mounting lugs.
Claim 6
Dependent Claim
46 words
The blade holder construction defined in claim 1 in which the ring includes an integrally connected annular-shaped top wall, a cylindrical-shaped side wall and an annular-shaped, radially inwardly extending ledge spaced from said top wall, with said walls and ledge forming the blade mounting groove therebetween.
Claim 7
Dependent Claim
19 words
The blade holder construction defined in claim 5 in which the ledge terminates in an outwardly downwardly extending edge.
Claim 8
Dependent Claim
44 words
The blade holder construction defined in claim 5 in which the cylindrical-shaped side wall terminates in a bottom edge which extends below the ledge; and in which the plastic lugs include portions extending along the cylindrical side wall and beneath the bottom edge thereof.
Claim 9
Dependent Claim
19 words
The blade holder construction defined in claim 1 in which the plastic lugs are formed of a polycarbonate material.
Claim 10
Dependent Claim
40 words
The blade holder construction defined in claim 1 in which a portion of the lug is spaced above an arcuate portion of the ring on both sides of the split to form a pair of circumferentially extending arcuate alignment grooves.
