A clamping apparatus having a fixed post with a pad and a clamping jaw post with a threaded hole, through which a screw with a handle on one end and a pad on the other passes. The clamping apparatus may be used with rails so that on the bottom rail the fixed post is placed within one hole and the clamping jaw post placed within another hole such that a workpiece may be clamped between the two, and additionally a top rail with holes that the other ends of the fixed and clamping jaw post engage with may be added to prevent the workpiece from buckling when clamping pressure is applied by turning the screw.

Panel clamping apparatus

An adjustable beading and grooving tool having a combination handle and fence within which a blade holder telescopes. The holder is a longitudinally slotted cylinder having two holder arms, or may be two half-cylinders, between which a blade may be fixed to project a desired distance from the holder, thereby establishing the depth of workpiece surface penetration. The blade holder is separately, adjustably fixed in the handle with the blade located a desired distance from the fence surface to establish the location of the profile to be formed with respect to the workpiece edge against which the fence bears during use.

Beading tool

A twin screw vise utilizing two threaded vise screw rods that are journaled through flanged nuts fixed to a workbench top or to a rear, fixed bench jaw. The vise screws pass through a movable front jaw and into tee-castings and handles that may be turned to rotate the screws. Sprockets are located on each screw between the tee castings and the front jaw and are coupled by a chain. One of the sprockets is fixed in position on its screw during a calibration procedure. The other sprocket remains free to rotate on its screw, except when a spring loaded pin in the corresponding tee-casting engages a depression in the face of the sprocket, thereby coupling that sprocket to the tee casting and associated screw.

Twin screw vise

A woodworking bench and related fixtures providing an integrated system of bench features, vises, dogs, panel clamps, hold-downs and fixtures that cooperate to provide a highly flexible workpiece holding and clamping apparatus able to accommodate a wide variety of shapes and sizes of workpieces and hold such workpieces in an enormous variety of positions during numerous different operations. Two substantial slabs provide the bench top surface and carry a rectilinear pattern (in rows and files) of round, vertical bench dog holes. The rectilinear pattern of round bench dog holes with specific, equal spacing between holes, and similar holes in the edge of the top, facilitate great flexibility in clamping using conventional round dogs in the bench top holes and corresponding dogs in bench edge-mounted, or end-mounted vises. Such holes also accommodate other clamping, fixing and hold-down fixtures that contribute to flexibility and utility. The two slabs are separated by a tool trough, and optional bench top ends or caps span the ends of the slabs, unify the bench top structure and provide a fixed jaw for an end-mounted twin screw vise. Optional skirts form a deep longitudinal edge for the top and join the ends to form a rectangular frame for the top. Dog holes in the edge of the top permit workpieces to be fixed along the bench edge using the hold-down, two clamping bench dogs, or a fixed dog and either of the clamping dog or the twin screw vise.

Woodworking bench system

A hold-down utilizing a round, interchangeable post having annular barb-like ridges or projections that engage a workbench top through round holes that may be located at substantially any desired positions in the bench top. The post threads into a hold-down body having, on one side of the post, a yoke within which a gooseneck-shaped hold-down arm pivots on a pin received in yoke arms or forks and, on the other side of the post, a screw pressure point and T-shaped slot for receiving the head of a clamping adjustment screw that is journaled through one end of the clamping arm. The other end of the clamping arm terminates in a foot with a rounded pad for exerting pressure against a workpiece.

Bench hold-down

A jig for drilling all the dowel and fixture mounting holes for the 32 mm system of cabinet construction consisting of a pair of parallel rails having face and side, a third rail identical to the two parallel rails and attached perpendicularly to the parallel rails, a saddle which straddles the rails and containing a bushing that fits through the saddle and into the holes of the rails and two asymmetric clamping frames having a clamping thumbscrew and a locating thumbscrew with a thread cut on a 1 mm pitch that rigidly attaches to one of the rails.

Drilling jig

A vise for holding a workpiece, comprising a pair of generally opposed jaws having substantially planar faces, a clamping screw having at least one external thread centered around a longitudinal axis rotatably attached at one end to one of the jaws and passing through the other jaw, a clamping screw nut having at least one internal thread occupying an arc of no more than approximately 180.degree. and having a substantially planar forward face for bearing against a substantially planar and parallel rear face of the other jaw when the clamping screw is rotated to draw the jaws together and both the forward and rear faces are oblique to the axis of the clamping screw, a rod attached to a handle that, when depressed, moves the rod so that its movement moves the nut substantially transverse to the axis of the clamping screw, a foot pedal attached to an actuator that, when the foot petal is depressed, moves the clamping nut substantially transverse to the axis of the clamping screw, at least one guide rod rigidly attached at one end to one of the jaws, and an elastic cord attached between the other end of the guide rod and the other jaw.

Adjustable vise

Apparatus for holding and storing sharpening stones that includes a water-tight reservoir which is open at the top and contains an integral supporting lip, bars that span the open top of the reservoir and are received within recesses in the reservoir sides, clamps on the rod to securely hold a sharpening stone in place, a lapping plate that rests within the integral supporting lip of the reservoir, and a dust cover which fits securely over the open top of the reservoir.

Apparatus for holding and storing sharpening stones

A multi-sided gauge and layout tool which includes the five angles needed in order to adjust or set-up woodworking and other machinery to fabricate multi-sided or multi-segmented structures having four, five, six, eight or twelve sides. A large knob with a flat bottom and a slot having a sloping bottom may be removably mounted in the middle of the gauge to facilitate grasping and manipulating the gauge when it is used flat against a work surface and may be removed and used as a base to hold the gauge body upright within the slot.

Machine setting gauge

A honing guide is provided in which a tool support plate is mounted above a surface-engaging roller. The surface-engaging roller is mounted eccentrically so that the height of the tool support plate may be varied to provide a range of honing angles without unclamping the tool from the guide.
