Abstract
A work bench has a stationary planar upper surface and a fence to which a piece of work is clamped. The fence may be moved so that the position of the work piece may be adjusted. Once in the desired position, the work piece remains immovable. A carriage slides beneath the upper surface and a router is mounted on the carriage. The router bit extends through an elongated slot in the upper surface and into contact with the immovable work piece. As the carriage slides the router cuts the work piece. The fence has a base which rotates on top of the upper surface and a bracket slides on rails formed on top of the base. Knobs are provided for tightening the base to the upper surface and the bracket to the base to prevent such rotation and sliding.
Claims13
A router table including:
- a table having a stationary planar upper surface and an elongated slot formed therein;
- a fence which is adjustably mounted on said upper surface and to which a work piece may be clamped such that the work piece may be adjustably positioned on said upper surface and maintained immovable in a desired position during the routing operation;
- a carriage slideably mounted beneath said upper surface;
- and a router mounted to said carriage and having a bit which extends through said slot and projects upwardly of said upper surface to engage the work piece, said bit cutting out an elongated groove in the immovable work piece as said carriage slides beneath said upper surface,
- said slot extending across said table and beneath said fence and defining an elongated path along which said bit travels as said carriage slides beneath said upper surface such that as said carriage slides, said bit cuts out an elongated groove in the immovable work piece, said fence having an opening above said slot through which said bit may pass.

A router table including:
- a table having a stationary planar upper surface and an elongated slot formed therein;
- a fence which is adjustably mounted on said upper surface and to which a work piece may be clamped such that the work piece may be adjustably positioned on said upper surface and maintained immovable in a desired position during the routing operation;
- a carriage slideably mounted beneath said upper surface;
- a router mounted to said carriage and having a bit which extends through said slot and projects upwardly of said upper surface to engage the work piece, said bit having an axis of rotation which travels in a straight line as said carriage slides beneath said table and which cuts out an elongated groove in the immovable work piece as said carriage slides beneath said upper surface;
- and
- said slot extending across said table and beneath said fence and defining an elongated path along which said bit travels as said carriage slides beneath said upper surface such that as said carriage slides, said bit cuts out an elongated groove in the immovable work piece, said fence having an opening above said slot through which said bit may pass.

A router table including:
- a table having a stationary planar upper surface and an elongated slot formed therein;
- a fence which is adjustably mounted on said upper surface and to which a work piece may be clamped such that the work piece may be adjustably positioned on said upper surface and maintained immovable in a desired position during the routing operation;
- a carriage slideably mounted beneath said upper surface;
- and a router mounted to said carriage and having a bit which extends through said slot and projects upwardly of said upper surface to engage the work piece, said bit having an axis of rotation which travels in a straight line as said carriage slides beneath said table and which cuts out an elongated groove in the immovable work piece as said carriage slides beneath said upper surface, said fence including a base mounted to said table for rotation about an axis lying on the projection of said straight line, and
- said slot extending across said table and beneath said fence and defining an elongated path alone which said bit travels as said carriage slides beneath said upper surface such that as said carriage slides, said bit cuts out an elongated groove in the immovable work piece, said fence having an opening above said slot through which said bit may pass.
2 more elements
A work bench for cutting a piece of work including:
- a fence having a base which is mounted to said table for rotation about an axis and which is disposed on its upper surface;
- first adjustment means for selectively preventing said base from rotating with respect to said upper surface;
- a bracket mounted to said base and having an elongated wall to which a work piece is clamped, said bracket being slidable relative to said base suck that the work piece may be caused to advance radially toward or to retreat radially from said axis;
- and
- second adjustment means for selectively fixing said bracket to said base for preventing said bracket from sliding relative to said base.

A work bench for cutting a piece of work including:
- a fence having a base which is mounted to said table for rotation about an axis which is disposed on its upper surface;
- first adjustment means for selectively preventing said base from rotating with respect to said upper surface;
- a bracket mounted to said base and having an elongated wall to which a work piece is clamped;
- second adjustment means for selectively fixing said bracket to said base for preventing said bracket from sliding relative to said base;
- said base having a rail which is accommodated in a groove formed in said bracket for allowing sliding but not rotation of said bracket relative to said base, said bracket having a pair of elongated parallel openings each receiving a separate threaded stud, each said stud being fixed to said base and extending through and projecting upwardly of said opening, a pair of knobs each having a threaded bore for mating with a separate said stud, rotation of said knob in one direction causing said knob to engage said bracket and to prevent sliding of said bracket with respect to said base and rotation of said knob in the opposite direction allowing said bracket to slide relative to said base.
