Abstract
Abstract A tool consists of a mounting member having adjustable grips which attach to the construction material and a carriage having a working tool is then movable relatively to the clamped construction material to perform work operations at selected locations. The clamps are adjustable within a bar or channel and once adjusted to the correct position within the channel and further adjusted relatively to the size of the construction material, the clamps are fixed in place and the channel is held fast. The carriage having a tool such as a drill, cutting blade, rip saw, etc. mounted on the carriage is then caused to slide back and forth on the channel to make selected working operations at given locations and the construction material can be plywood, studs, sheet goods and the like.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A device for clamping a work piece and performing a work operation thereon comprising an elongate member, at least two gripping means slidably supported on said elongate member for movement in the longitudinal direction thereof, each of said gripping means being selectively positionable along said elongate member to hold work pieces of various lengths and being selectively adjustable to clamp work pieces of various thicknesses to the elongate member, said gripping means being actuable between clamping and non-clamping positions, each of said gripping means including adjustment means operative in the non-clamping position to cause said gripping means, when actuated into the clamping position, to adjust itself to accommodate a work piece of predetermined thickness, carriage means slidably carried on said elongate member, and tool means supported by said carriage means for effecting a work operation on the work piece.
Claim 2
Independent Claim
139 words
A device for clamping a work piece and performing a work operation thereon comprising an elongate member, at least two gripping means slidably supported on said elongate member for movement in the longitudinal direction thereof, each of said gripping means being selectively positionable along said elongate member to hold work pieces of various lengths and being selectively adjustable to clamp work pieces of various thicknesses to the elongate member, said gripping means being actuable between clamping and non-clamping positions, each of said gripping means including adjustment means operative in the non-clamping position to cause said gripping means, when actuated into the clamping position, to adjust itself to accommodate a work piece of predetermined thickness, carriage means slidably carried on said elongate member, and tool means supported by said carriage means for effecting a work operation on the work piece.
Claim 3
Dependent Claim
39 words
The tool in accordance with claim 1 including a cutting member operatively carried by said carriage, and leverage means for imposing a work effort on said tool through said leverage means to effect a cutting operation on the workpiece.
Claim 4
Dependent Claim
31 words
