Movable fence for a machine tool
First Claim
1. A table saw comprising:
- a table having a width;
a cutting tool protruding from the table;
a first and a second rail movably connected to the table;
a supplemental support connected to the first and second rails the supplemental support having a workpiece abutment;
a first and a second scale disposed on the first rail said second scale being partially coextensive with said first scale;
a first pointer connected to the table, said first pointer pointing to said first scale to indicate a first distance between the cutting tool and the workpiece abutment within a first distance range when the workpiece abutment is on a first side of said cutting tool,a second pointer connected to said table, said second pointer pointing to said second scale to indicate a second distance between the cutting tool and the workpiece abutment within a second distance range when the workpiece abutment is on said first side of said cutting tool, said second distance range being non-coextensive with said first distance range.

Abstract
An adjustable rip fence for a machine tool has a fence which is movable with respect to the cutting tool due to a rack and pinion. The rail assembly supporting the fence include a pair of stationary rails which are secure to the machine tool. A movable rail telescopically engages each stationary rail and the movement of each rail is accomplished by the rotation of a pair of pinion gears each of which engages a respective rack on the movable rails. The simultaneous rotation of the pinion gears is the result of both pinion gears being secured to a common pinion shaft which is rotatably secured to the machine tool. The telescoping nature of the rails allows for adjustment of the fence beyond the working surface of the machine tool. A pair of scales is disposed on one of the movable rails.
