Abstract: A pinless router comprising a router coupled to a movable support arranged and configured such that it has at least one separable portion which may be decoupled from the remainder of the support, a means for vertically moving the router and the support, a helical brush having a large central opening concentric with the router tool and which engages with a work piece when the pinless router is in operation, a means for moving the router together with the support in a horizontal plane, a means for decoupling the separable portion from the remainder of the support and a continuous vacuum applied to the central opening in the brush.In operation, the pinless router is moved downwardly until the brush engages with the surface of the work piece. The routing operation is then substantially performed until just before the routing is completed. The pinless router is then stopped and moved downwardly until the separable portion engages with the work piece.

Abstract: An adjustable holding and alignment device is provided for a workpiece having alignment pins. The device has a plurality of bars separated by spacers which define an alignment hole and an alignment slot through which the workpiece alignment pins may be inserted. The spacers can be removed and different sized spacers can be substituted to accommodate other alignment pin sizes.

Abstract: A novel arrangement of pressure foot and drive therefor for providing a frictional clamping arrangement for holding a workpiece being cut by a router so as to prevent movement of the cutout portion of the workpiece in the last increment of the cut. The pinless pressure foot includes a ring-shaped friction member supported by a slide member adjacent one end of a spindle, circumscribing a cutting tool, for engaging the surface of the workpiece. A plurality of flexure members extend around the spindle, first ends of the flexure members being connected to the slide member.

Abstract: An improved chuck utilizing a self-contained hydraulic system integrated to the spindle rotor to radially flex a thin walled diaphragm so as to grip a collet and a tool therein. Pressure in the hydraulic system is controlled by means of a plunger which is forced to a position which compresses the hydraulic fluid by means of a spring. The plunger may be pushed against the action of the spring in order to decompress the fluid by means of a mechanical release which is removed from the plunger during the operation of the chuck. A built-in hydraulic amplification system achieves high clamping pressure with a small actuating force. Accordingly, only a small actuating force is also required to relieve the clamping pressure so that the chuck bearings are not overloaded while the tool is being released.
