Movable fence for a machine tool
First Claim
1. A machine tool having a base, said machine tool comprising:
- a first stationary rail connected to said base extending generally along a first direction, said stationary rail having a first and a second end;
a first movable rail received over said first stationary rail and extending generally parallel to said first stationary rail; and
a fence assembly including;
a fence extending generally perpendicular to said first movable rail; and
a first mount connected to said fence and adapted to engage said first movable rail, said first movable rail being movable with respect to said first stationary rail between a first position where said fence assembly is located between said first and second ends and a second position where said fence assembly is located beyond one of said first and second ends, said fence assembly being attached to said first movable rail in both said first and second positions.

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.
