A biscuit joiner for cutting semi-elliptical slots in opposing edges of workpieces which are to be joined along those edges includes a housing adapted to be mounted upon the quill of a multi-purpose woodworking tool, which housing encloses a rotary saw blade adapted to be attached to a spindle projecting from the quill on which the housing is mounted. A spring loaded guide projects from the front face of the housing and has a slot therethrough, so that when the front face of the guide is engaged by an edge of a workpiece to be slotted the guide can be pushed inwardly against spring pressure, allowing the rotary saw blade to be exposed and form a slot in the edge of the workpiece. Adjustable stops are provided on the guide so that a desired depth of cut will automatically be made after adjustment. An alternative construction of this biscuit joiner is especially adapted for use in conjunction with a conventional drill press, with the arbor which carries the saw blade being clamped in the chuck on the drive spindle of the drill motor.

A saw guard system adapted to be mounted on the headstock quill of a multipurpose woodworking tool includes a rear portion adapted to be clamped to the headstock quill, a front portion which forms a pocket with the rear portion and is adjustable so that the pocket size can be varied to accommodate rotary tools of varying thicknesses, and an exhaust port communicating with the pocket and having an outer end adapted to be attached to a vacuum hose. The rear portion supports a riving knife adapted to extend above an associated saw table and which includes an upper saw guard. The riving knife is positioned in a common plane with a rotary tool mounted on the quill, and is capable of remaining closely adjacent to the rotary tool regardless of table position or quill extension. An anti-kickback device includes a finger having a downwardly-extending point and is connected to the riving knife by a pair of link arms so that the horizontal orientation of the finger remains constant regardless of its elevation relative to the riving knife. To facilitate retention of dust in the pocket, as well as its removal through the port, the front portion includes a transverse channel at its lower end communicating with the port, the rear portion includes a deflector plate above the port, and the port is skewed relative to the front portion and is located at a downstream side of the pocket.

Saw table

A tilting table for a woodworking tool comprising a support member, a pair of trunnions pivotally attached to the support member for movement about a common axis, a table top attached to and supported by the trunnions, a pair of wedge blocks mounted to slidably engage the trunnions and support member, and carried on a rod having a nut threaded thereon such that inward displacement of the nut urges the wedge blocks toward each other, thereby jamming the wedge blocks between the trunnions and the support member. The wedge blocks are spring loaded such that outward displacement of the nut allows the wedge blocks to be urged outwardly from their jamming engagement, thus permitting the table top and trunnions to be pivoted relative to the support member.
