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: An adjustable stop mechanism for limiting the movement of a rip fence toward the cutting plane of a tiltable panel saw as an automatic function of the selected orientation of an abutment bar. The abutment bar has first and second orientations alternately presenting an abutment face of relatively low height, located at a greater distance from a reference surface, and a relatively greater height, located at a relatively shorter distance from the reference surface. When the abutment bar is rotated to the low height orientation, as to accommodate tilting of the panel saw blade, a limit stop position of movement of the abutment bar toward the cutting plane is automatically altered, so that the limit stop for the abutment bar support is farther away from the cutting plane. When the bar is oriented to present a full height abutment face, the limit stop automatically is altered in response to such orientation, to permit the support to move closer to the cutting plane.

Abstract: A fence for a saw table includes a threaded shaft rotatably mounted parallel to one side edge of the saw table platform and a guide fence operably mounted on the shaft to move longitudinally as the shaft is rotated.

A handle mounted on the end of the threaded shaft permits longitudinal movement of the guide fence along the saw table. A wheel mounted on the free end of the guide fence supports the guide fence end slightly above the surface of the saw table.

Abstract: In a copier, automatically providing tabbed sheets in the output of the copy sheets of the copier, with an integral, on-line, copy sheet tab cutting system. Selectably varying the tab cutting position and cut tab size provides sequentially varied tabs. A selected tab may be cut on any selected sheet being fed through the regular copy sheet (paper) path of a xerographic or other copier or printer. This may be done by temporarily stopping and registering the leading edge of the selected sheet, and then shear cutting off the untabbed areas of the trailing edge of the sheet by moving an shear cutting assembly transversely across the direction of movement of the copy sheet path of the copier upstream of the lead edge registration position at slightly less than the sheet width distance, and providing irregular width cutting of the sheet (non-cutting of the tab area).

Abstract: A removable fence for a table saw is positioned on a saw table by a locking mechanism located on the fence which simultaneously grips a pair of blocks mounted on an endless flexible cable. The locking mechanism engages the blocks and raises them into frictional relation with an L-bracket mounted on the table thus preventing movement of the fence. The blocks are affixed to the cable at points equidistant from the plane of the saw blade thereby insuring parallelism of the fence relative to the plane of the saw blade. Utilizing the flexibility of the cable which permits lateral movement, the fence is removed by releasing the locking mechanism and moving the blocks laterally away from the mechanism.
