Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
In a machine for beveling the edge of a generally planar workpiece such as a printed circuit board, a generally rectangular enclosure having a stepped top with an offset portion extending along one edge below the remainder of the top, a fixed cover portion extending along the edge of the top opposite to said one edge, a movable cover member mounted between the offset portion and the fixed cover portion and cooperating with said portions to enclose the top of the enclosure, said movable cover member having a depending skirt portion disposed along the edge of the same adjacent to the offset portion, a circular cutting blade mounted for rotation about an axis within the enclosure, a portion of the blade extending through openings in the offset and skirt portions and being exposed externally of the enclosure, workpiece guide surfaces carried by the offset portion and the skirt portion, said guide surfaces intersecting along a line generally parallel to the axis of blade rotation and being adapted for slidably receiving a workpiece and guiding one edge of the same into the exposed portion of the blade in a direction generally parallel to the axis of rotation.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
48 words
A beveling machine as defined in claim 1 further including means for adjusting the position of the cover member between the offset portion and the fixed cover portion to adjust the depth of a cut made by the blade relative to the guide surface carried by the cover.
Claim 4
Dependent Claim
68 words
A beveling machine as defined in claim 2 wherein the means for adjusting the position of the cover member includes a block rigidly affixed to the cover member and extending upwardly through an opening in the fixed cover portion, and a pair of adjusting screws threadedly mounted on the fixed cover portion and engaging opposing surfaces of the block, said adjusting screws being accessible externally of the enclosure.
Claim 5
Dependent Claim
53 words
A beveling machine as defined in claim 1 further including means for adjusting the position of the axis of rotation in a plane disposed obliquely of the guide surfaces to adjust the angle between the cutting edge of the exposed portion of the blade and the guide surface carried by the offset portion.
Claim 6
Dependent Claim
78 words
A beveling machine as defined in claim 4 wherein the blade is mounted on a shaft carried by a support member movable in a direction parallel to the obliquely disposed plane, and wherein the means for adjusting the position of the axis includes a threaded member connected to the support member and extending through a wall of the enclosure and an adjusting nut threadedly mounted on the threaded member and bearing against the outer surface of said wall.
Claim 7
Dependent Claim
29 words
A beveling machine as defined in claim 5 wherein the threaded member is provided with calibration markings indicative of the angle between the cutting edge and the guide surface.
