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.

Abstract: A workpiece-supporting fence has a pair of movable fences movably attached to a fixed fence which is secured to a base of the device in which the fence is being used.

The positioning process and the saw selection for each cut are scanner/computer controlled.

Abstract: A safety device for a radial arm saw is presented. The device is readily attached to a radial arm saw by attaching it to the top of the table and the guide rail. The safety device has a three-sided, box-shaped handle part, which has a circular gripping handle between two of the sides. The handle is attached to a slide bar which slides through a carriage unit. The front face plate of the handle has a number of spring-loaded anti-kickback pins on one side. These anti-kickback pins are pushed in by the workpiece and the remaining, protruding, pins keep the workpiece against the table. The handle pivots upwardly from the slide bar. When it is desired to load a board onto the table for cutting, the handle is rotated up. Once the board is loaded the handle is rotated down and pushed forward. The front face plate holds the board against the guard rail and the anti-kickpins hold the board down. Once in that position, the saw blade can be pulled across the board, thus cutting the board.
