Abstract
Abstract An apparatus for shaping a wooden workpiece according to a template configuration has a carriage displaceable on a track parallel to a guide edge of a template clamped on a table to one side of the track. A workpiece is clamped to a table to the opposite side of the track. A slide is displaceable on the carriage transverse to the track and carries on one end a roller engaging the guide edge of the template and on its other end a driven tool for cutting the shape of the template into the workpiece. The slide is urged toward the workpiece so that virtually no lateral force is exerted against the workpiece, the guide edge acting as a stop positively determining the transverse position of the slide. Another template can support a second feeler roller which is connected via a chain or the like to the tool to raise and lower this tool according to the guide edge on the second template for two-sided cutting of the workpiece.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
259 words
An apparatus for reproducing the shape of a guide edge of a template in a wooden workpiece, said apparatus comprising: a support; a straight tool track on said support; a carriage displaceable along said tool track; means for displacing said carriage along said tool track; a template table fixed on said support next to said tool track; means for securing said template to said template table with said guide edge facing in one direction transverse to said track; a straight workpiece track on said support parallel to said tool track; a succession of workpiece tables displaceable along said workpiece track next to said tool track and past said template table; means for securing respective wooden workpieces to said workpiece tables; a slide on said carriage displaceable transverse to said track; a roller on said slide engageable in the opposite direction transverse to said tracks with said edge of said template; means on said carriage for urging said slide in said opposite direction for forcibly biasing said roller against said edge, said edge serving as a stop for said slide in said opposite direction; a material-removing tool on said slide engageable with some of the workpieces adjacent said carriage; and means on said carriage for rotating said tool on displacement of said carriage along said track for reproducing in said workpiece the shape of said edge whereby said tool exerts substantially no force upon the workpiece in said directions. in said workpiece the shape of said edge whereby said tool exerts substantially no force upon the worKpiece in said directions.
Claim 2
Independent Claim
259 words
An apparatus for reproducing the shape of a guide edge of a template in a wooden workpiece, said apparatus comprising: a support; a straight tool track on said support; a carriage displaceable along said tool track; means for displacing said carriage along said tool track; a template table fixed on said support next to said tool track; means for securing said template to said template table with said guide edge facing in one direction transverse to said track; a straight workpiece track on said support parallel to said tool track; a succession of workpiece tables displaceable along said workpiece track next to said tool track and past said template table; means for securing respective wooden workpieces to said workpiece tables; a slide on said carriage displaceable transverse to said track; a roller on said slide engageable in the opposite direction transverse to said tracks with said edge of said template; means on said carriage for urging said slide in said opposite direction for forcibly biasing said roller against said edge, said edge serving as a stop for said slide in said opposite direction; a material-removing tool on said slide engageable with some of the workpieces adjacent said carriage; and means on said carriage for rotating said tool on displacement of said carriage along said track for reproducing in said workpiece the shape of said edge whereby said tool exerts substantially no force upon the workpiece in said directions. in said workpiece the shape of said edge whereby said tool exerts substantially no force upon the worKpiece in said directions.
Claim 3
Dependent Claim
27 words
The apparatus defined in claim 1 wherein said roller is rotatable about a roller axis, said tool being rotatable about an axis coplanar with said roller axis.
Claim 4
Dependent Claim
36 words
The apparatus defined in claim 2 wherein said workpiece table is located to one side of said track and said template table is located to the other side of said track across from said workpiece table.
Claim 5
Dependent Claim
59 words
The apparatus defined in claim 2, further comprising means for securing a second template to said template table, a second roller carried on said slide and engaging the guide edge of said second template, and means positively linking said second roller to said tool for vertically displacing said tool on displacement of said second roller by said second template.
Claim 6
Dependent Claim
49 words
The apparatus defined in claim 4 wherein said second template has a second guide edge extending substantially parallel to said track, said apparatus further comprising means for urging said second roller against said edge, said means positively linking said second roller to said tool being a nonextensible flexible element.
Claim 7
Dependent Claim
21 words
