Abstract
Abstract The specification discloses a cutting tool especially useful for cut-off and grooving operations. The tool comprises a relatively massive block-like body with a plate adjustably mounted on one side and having a V-groove in the top toward one end extending longitudinally of the plate and adapted to receive an elongated cutting element having a ridge on the bottom engaging said groove, or a short cutting element with an elongated clamping bar both seated in the groove and held in place by a clamp mounted on the block.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
210 words
In a tool for grooving or cut-off operations; a support block, a support plate clamped to one longitudinal side of said block and having one end projecting beyond the end of said block, said plate having an upper edge and an elongated V-groove in said upper edge of said plate, a bar-like element having a V-ridge along the bottom lower edge adapted to be received in said groove with one end disposed near said one end of said plate, a clamp member on the block adapted to engage said bar-like element on the top between the ends thereof and clamp the said bar-like element to the upper edge of said plate, cutting element means at said one end of said bar-like element and fixed against longitudinal movement relative to said bar-like element, and means for adjusting said cutting element means together with at least one of said bar-like element and said plate and bar-like element together in the longitudinal direction of said block, at least one of said groove in the upper edge of said plate and said ridge on the lower edge of said bar-like element being concave toward the other in the longitudinal direction whereby only the ends of said bar-like element takes a Bearing on said plate.
Claim 2
Dependent Claim
210 words
In a tool for grooving or cut-off operations; a support block, a support plate clamped to one longitudinal side of said block and having one end projecting beyond the end of said block, said plate having an upper edge and an elongated V-groove in said upper edge of said plate, a bar-like element having a V-ridge along the bottom lower edge adapted to be received in said groove with one end disposed near said one end of said plate, a clamp member on the block adapted to engage said bar-like element on the top between the ends thereof and clamp the said bar-like element to the upper edge of said plate, cutting element means at said one end of said bar-like element and fixed against longitudinal movement relative to said bar-like element, and means for adjusting said cutting element means together with at least one of said bar-like element and said plate and bar-like element together in the longitudinal direction of said block, at least one of said groove in the upper edge of said plate and said ridge on the lower edge of said bar-like element being concave toward the other in the longitudinal direction whereby only the ends of said bar-like element takes a Bearing on said plate.
Claim 3
Dependent Claim
61 words
A tool according to claim 1 in which said plate has a notch formed therein at said one end, and a hard seat member fixed in said notch and having a groove on the upper edge forming a continuation of the groove in the upper edge of said plate and adapted to form a bearing surface for said cutting element means.
Claim 4
Dependent Claim
30 words
A tool according to claim 1 in which said groove when viewed from the side of said plate is concave in the upward direction and said bar-like element is straight.
Claim 5
Dependent Claim
40 words
A tool according to claim 1 in which said bar-like element is formed of cemented hard metal carbide and has the sides thereof at said one end divergent toward said one end and serving as the said cutting element means.
Claim 6
Dependent Claim
74 words
A tool according to claim 1 in which said bar-like element at said one end thereof has a nose portion projecting longitudinally from the upper portion, said cutting element means comprising a hard element substantially shorter than said bar-like element and having a ridge on the bottom resting in said groove and having a transverse ledge at the end facing said one end of said bar-like element, said nose portion clampingly engaging said ledge.
Claim 7
Dependent Claim
47 words
A tool according to claim 1 in which said bar-like element at said one end has a notch formed therein open at the top and on the side facing said one end of said bar-like element, and said cutting element means being fixedly mounted in said notch.
Claim 8
Dependent Claim
84 words
A tool according to claim 2 in which said bar-like element at said one end thereof has a nose portion projecting longitudinally from the upper portion, said cutting element means comprising a hard element substantially shorter than said bar-like element and having a ridge on the bottom resting in said groove and having a transverse ledge at the end facing said one end of said bar-like element, said nose portion clampingly engaging said ledge, said cutting element means resting on said hard seat member.
Claim 9
Dependent Claim
37 words
A tool according to claim 1 in which the upper edge of said plate comprises an upstanding portion at the rear end of the said groove forming abutment means for the rear end of said bar-like element.
Claim 10
Dependent Claim
24 words
