Abstract
Abstract In an apparatus for feeding elongated stock to a work station, an improved vise for securely holding the stock against a work surface to prevent rotation of the stock. The vise includes opposed lateral guides extending upwardly from the work surface parallel to the direction of feed and a top guide having front and rear bearing portions both opposing the work surface. The top guide is shaped so that the front bearing portion is closer to the work surface to firmly hold the stock against rotation. The shaping of the top guide may be eliminated by the addition of a thin bearing plate onto the front portion. This thin plate may be tapered rearwardly for longer life. The lateral guides may also be shaped or may include thin bearing plates.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
In an apparatus for feeding elongated stock toward a work station said stock having a leading end and a trailing end, and being supported by a work surface, said apparatus including side members generally perpendicular to the work surface and parallel to the direction of feed, each having front and rear bearing portions and a top guide member having a front bearing portion and a rear bearing portion, both opposing said work surface, the improvement comprising: said front bearing portion of at least one of said members being spaced closer to said work surface than said rear bearing portion for concentrating the force of said member onto said elongated stock and for holding said stock firmly between said side members said top member and said work surface against rotation.
Claim 2
Dependent Claim
129 words
In an apparatus for feeding elongated stock toward a work station said stock having a leading end and a trailing end, and being supported by a work surface, said apparatus including side members generally perpendicular to the work surface and parallel to the direction of feed, each having front and rear bearing portions and a top guide member having a front bearing portion and a rear bearing portion, both opposing said work surface, the improvement comprising: said front bearing portion of at least one of said members being spaced closer to said work surface than said rear bearing portion for concentrating the force of said member onto said elongated stock and for holding said stock firmly between said side members said top member and said work surface against rotation.
Claim 3
Dependent Claim
36 words
The invention as defined in claim 1, wherein said at least one member includes a pressure plate on said front bearing portion, said pressure plate terminating intermediate the front and rear bearing portions of the member.
Claim 4
Dependent Claim
39 words
The invention as defined in claim 2 wherein said pressure plate is tapered from a thicker portion at said front bearing portion of said member to a thinner portion intermediate said front and rear bearing portions of said member.
Claim 5
Dependent Claim
16 words
The invention as defined in claim 2 wherein said member includes a plurality of pressure plates.
Claim 6
Dependent Claim
51 words
The invention as defined in claim 1 wherein said top guide member has its front bearing portion spaced closer to said work surface and wherein the surface of said top guide opposing said work surface includes a tapered portion, said taper being progressively thicker in the direction of feeding said stock.
Claim 7
Dependent Claim
20 words
The invention as defined in claim 1 wherein said top guide member includes a downward projection opposing said work surface.
Claim 8
Dependent Claim
22 words
The invention as defined in claim 6 wherein said downward projection is tapered increasing thicker in the direction of feeding said stock.
Claim 9
Dependent Claim
23 words
The invention as defined in claim 1 wherein said at least one member includes a discrete pressure plate on said front bearing portion.
