Abstract
Abstract A wire is passed along an axial path through a housing having a frame driven rotatably about the axis of the path. A plurality of angularly equispaced arms mounted on shafts parallel to the axis each carry a respective grinding member having a central bore which is aligned with the axis so that the inner surface of the bore is the active grinding surface effective on the outer surface of the wire. The grinding members are rotated and/or the wire is rotated for grinding action across the displacement direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
An apparatus for grinding wire comprising: means for displacing said wire along a straight path; a frame journaled for rotation about an axis lying along said path; an arm swingably mounted on said frame about a pivot offset from said axis; a grinding body formed with a bore traversed by said wire and having an abrasive wall, said grinding body being rotatably mounted on said arm; first driving means operatively connected with said frame for rotating same about said axis; and second driving means operatively connected with said grinding body for rotating same to abrade the exterior surface of said wire against said wall.
Claim 2
Independent Claim
104 words
An apparatus for grinding wire comprising: means for displacing said wire along a straight path; a frame journaled for rotation about an axis lying along said path; an arm swingably mounted on said frame about a pivot offset from said axis; a grinding body formed with a bore traversed by said wire and having an abrasive wall, said grinding body being rotatably mounted on said arm; first driving means operatively connected with said frame for rotating same about said axis; and second driving means operatively connected with said grinding body for rotating same to abrade the exterior surface of said wire against said wall.
Claim 3
Dependent Claim
24 words
The apparatus defined in claim 1, wherein a plurality of such grinding members are carried on said frame and angularly equispaced about said axis.
Claim 4
Dependent Claim
19 words
The apparatus defined in claim 1 wherein each of said drive means includes a motor and a V-belt drive.
Claim 5
Independent Claim
126 words
A method of grinding the outer surface of an elongated workpiece, comprising the steps of: displacing said workpiece longitudinally through a bore having an abrasive wall in an annular grinding member; swinging said annular grinding member against said workpiece about an orbital axis parallel to but spaced from the axis of said workpiece; confining said workpiece to a straight line path during said displacement and through said bore; rotating said orbital axis about said axis of said workpiece; and concomitantly rotating said grinding member about said workpiece with said wall of said bore in contact with the outer surface of said workpiece whereby the rotation of said orbital axis about said workpiece brings said abrasive wall into contact with substantially the entire periphery of said workpiece.
Claim 6
Independent Claim
