Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
215 words
A cutting tool comprising: an elongated bar member having a wedge-shaped recess at one end thereof, one side of which terminates in a flat surface, the other side of which opens away from said bar member and the bottom of which is formed by a pair of generally and substantially mutually perpendicular surfaces connected by a generally curved surface, said perpendicular surfaces being upwardly inclined, relative to the longitudinal axis of said bar member, as viewed from their intersections; a wedge shaped anvil member rigidly and removably fastened in said wedge-shaped recess and having an elongated recess in which a cutting insert may be received, at least one side of said wedge-shaped anvil member being flat and lying against said flat surface of said wedge-shaped recess, the bottom of said wedge-shaped anvil member resting against said pair of mutually perpendicular surfaces, said anvil member being fastened in said recess by a single screw disposed in a countersunk hole therein for engagement with a threaded hole in said flat surface of said recess and the tightening of which wedges said anvil member between said pair of mutually perpendicular surfaces forming the bottom of said wedge-shaped recess; and a clamp member removably fastened to said bar member for rigidly clamping said cutting insert in said elongated recess.
Claim 2
Dependent Claim
215 words
A cutting tool comprising: an elongated bar member having a wedge-shaped recess at one end thereof, one side of which terminates in a flat surface, the other side of which opens away from said bar member and the bottom of which is formed by a pair of generally and substantially mutually perpendicular surfaces connected by a generally curved surface, said perpendicular surfaces being upwardly inclined, relative to the longitudinal axis of said bar member, as viewed from their intersections; a wedge shaped anvil member rigidly and removably fastened in said wedge-shaped recess and having an elongated recess in which a cutting insert may be received, at least one side of said wedge-shaped anvil member being flat and lying against said flat surface of said wedge-shaped recess, the bottom of said wedge-shaped anvil member resting against said pair of mutually perpendicular surfaces, said anvil member being fastened in said recess by a single screw disposed in a countersunk hole therein for engagement with a threaded hole in said flat surface of said recess and the tightening of which wedges said anvil member between said pair of mutually perpendicular surfaces forming the bottom of said wedge-shaped recess; and a clamp member removably fastened to said bar member for rigidly clamping said cutting insert in said elongated recess.
Claim 3
Dependent Claim
45 words
A cutting tool as defined in claim 1 in which said flat surface of said wedge-shaped recess is parallel to the longitudinal axis of said bar member so that the longitudinal axis of said elongated recess is also parallel to said bar member longitudinal axis.
Claim 4
Dependent Claim
45 words
A cutting tool as defined in claim 1 in which said flat surface of said wedge-shaped recess is perpendicular to the longitudinal axis of said bar member so that the longituinal axis of said elongated recess is also perpendicular to said bar member longitudinal axis.
Claim 5
Dependent Claim
45 words
A cutting tool as defined in claim 1 in which said bar member is relieved adjacent said flat surface of said wedge recess and said cutting insert, permitting said elongated recess to receive cutting inserts of widths greater than the width of said anvil member.
Claim 6
Dependent Claim
59 words
A cutting tool as defined in claim 1 in which said clamp member is rectangular-like in construction and provided at one end thereof with a depending rib for disposition in a corresponding recess in said bar member, rigidly aligning the opposite end of said clamp member for engagement with a cutting insert to be received in said elongated recess.
Claim 7
Dependent Claim
39 words
A cutting tool as defined in claim 5 in which said clamp member is provided at said opposite end with a second rib for bearing against said cutting insert, leaving a relieved area between said first and second ribs.
