Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
In apparatus for trimming a paper article, the combination comprising: a base; a base roller mounted on said base; means for severing a work piece mounted on said base adjacent said roller; means for holding said work piece flat and aligned laterally with respect to said severing means, which holding means includes: a laterally adjustable work piece support; and, means for rotatably biasing said work piece against said work piece support; means for indicating the lateral position of said severing means relative to said holding means; and means contacting said base roller for advancing said work piece past said severing means.
Claim 2
Dependent Claim
101 words
In apparatus for trimming a paper article, the combination comprising: a base; a base roller mounted on said base; means for severing a work piece mounted on said base adjacent said roller; means for holding said work piece flat and aligned laterally with respect to said severing means, which holding means includes: a laterally adjustable work piece support; and, means for rotatably biasing said work piece against said work piece support; means for indicating the lateral position of said severing means relative to said holding means; and means contacting said base roller for advancing said work piece past said severing means.
Claim 3
Dependent Claim
89 words
In apparatus for trimming a paper article, the combination comprising: a base; a base roller mounted on said base; means for severing a work piece mounted on said base adjacent said roller; means for holding said work piece flat and aligned laterally with respect to said severing means, which holding means includes a laterally adjustable work piece support and means for rotatably biasing said work piece vertically and laterally against said work piece support; and, means contacting said base roller for advancing said work piece past said severing means.
Claim 4
Dependent Claim
89 words
In apparatus for trimming a paper article, the combination comprising: a base; a base roller mounted on said base; means for severing a work piece mounted on said base adjacent said roller; means for holding said work piece flat and aligned laterally with respect to said severing means, which holding means includes a laterally adjustable work piece support and means for rotatably biasing said work piece vertically and laterally against said work piece support; and, means contacting said base roller for advancing said work piece past said severing means.
Claim 5
Dependent Claim
101 words
In apparatus for trimming a paper article, the combination comprising: a base; a base roller mounted on said base; a cutter disc contacting said base roller having an axis of rotation substantially parallel to the axis of said base roller; means forming a line of contact with said base roller for advancing a workpiece between said base roller and said cutter discs; and, means for laterally aligning a workpiece relative to said cutter disc, including: an indicator mounted on said base aligned with said cutter disc; a laterally adjustable workpiece support; and, means for rotatably biasing said workpiece against said support.
Claim 6
Dependent Claim
101 words
In apparatus for trimming a paper article, the combination comprising: a base; a base roller mounted on said base; a cutter disc contacting said base roller having an axis of rotation substantially parallel to the axis of said base roller; means forming a line of contact with said base roller for advancing a workpiece between said base roller and said cutter discs; and, means for laterally aligning a workpiece relative to said cutter disc, including: an indicator mounted on said base aligned with said cutter disc; a laterally adjustable workpiece support; and, means for rotatably biasing said workpiece against said support.
Claim 7
Dependent Claim
24 words
The invention as claimed in claim 3, wherein said biasing means includes: a wheel frictionally biasing said workpiece downwardly and laterally against said support.
