Abstract: A clamping device is capable of engaging a clamping object with an inner wall of hole or side wall of the clamping object. The clamping device 1 is provided with a rod support for moving an engagement portion 25 of a clamping rod 3 in a direction roughly rectangular to the longitudinal direction of the clamping rod 3 and switchably rotatably supports the clamping rod 3 in a clamping main body across a clamping position and a clamp release position, a piston drive mechanism 6 for driving a piston 4 across the clamping position and the clamp release position, and a cam mechanism 7 for driving the engagement portion 25 in the clamping direction by the driving force of piston drive mechanism 6 for driving the piston 4 to the clamping position.

Abstract: The present invention is a jig system for precisely positioning the placement of multiple cuts such as in the placement of dovetail or box joints cut in a wood panel. A row of multi-use adjustable spacers controls the indexing of a workpiece and can be used with a stationary and/or a portable cutting tool. The movability of the spacers permits a workpiece to be cut on both sides of a guide bar fence thereby assuring that the first cut will always be made on the same side of a drawer and will be esthetically pleasing regardless of the width of the workpiece. Additionally, the adjustability of the spacers accommodates any desired cutting tool height, angle and/or size.

Abstract: A support structure for laterally supporting a workpiece in a vertical lathe so as to hold the axis of the workpiece aligned with the vertical support axis of the lathe. The support structure includes a rod which is vertically supported on the lathe. The rod supports a movable locator rest assembly. The locator rest assembly includes a horizontally extending rod which terminates in a part rest which can be positioned so as to engage and support the workpiece in a precisely vertical manner.

Abstract: A food slicing device that holds food, particularly bread, in place while slicing. The bottom of the bread loaf is pierced to hold the loaf in place while slicing. Adjustment plates provide for varying slice width, or duplicating a slice of standard thickness. Adjustment plates may be stored on the back of the slicer. Grooves guide the knife when cutting bread. Cutting channels insure a cut completely through the item being sliced. A removable insert allows the top of the cutting platform to be replaced when it becomes abraded or damaged. The device is easily made by the home craftsman or can be mass produced.

Abstract: An anchor plate is arranged for cooperation with an underlying mounting plate to position a cabinet therebetween, wherein the anchor plate includes in a first embodiment a slide block mounted within a slot within the anchor plate, and the slide block hingedly mounting a mounting leg, including a flange for abutment with a forward surface of the cabinet for positioning the cabinet during a mounting procedure. A modification of the invention includes a generally serpentine securement leg slidably mounted within a channel defined by an anchor plate structure, wherein the securement leg includes a plurality of spaced abutments arranged in a parallel relationship to provide for positioning of the cabinet in communication with one of said abutments for positioning the cabinet during a mounting procedure.

Abstract: This invention is an apparatus for supporting a plurality of sample preparation cartridge units to expedite the handling of sample preparation. The apparatus comprises a pair of plates in space parallel relation. The first plate is mounted on end posts and the second plate is supported over the first plate by apparatus which adjustably raise and lower the second plate. The first and second plates are provided with notches along the longitudinal sides of the plates which are in vertical alignment. An elongated bar is hingedly connected between the plates and provided with apparatus to lock along the longitudinal side of the plates. The sample preparation cartridges which generally comprise a cylindrical body and cylindrical stems concentrically extending from the cartridge body, are placed between the plates so that the stems enter vertically aligned notches.

Abstract: Apparatus for holding a wet clay sculpture during the drying process which includes a base portion having post receiving apertures equidistantly spaced about its periphery; at least three vertically extending posts rotatably seated in the apertures, the posts having vertically spaced horizontal openings; and a plurality of horizontally extending support members slidingly engaging the openings for contacting and holding the sculpture in place. Pivotal sculpture contact members attachable to the support members may also be provided.

Abstract: A rip fence for table saws extensively used in woodworking. The rail of the fence is made in two parts, the lower one being vertically adjustable to provide a minimum table clearance.

Abstract: Apparatus for making substantially impenetrable members such as wall and floor members for bank vaults or the like. A fixture is used which facilitates the assembly of a plurality of expanded sheet metal members in a spaced stack thereof. Rod members are inserted transversely of the expanded sheet metal members with at least some of the rods extending beyond the sides of the spaced stack of expanded sheet metal members. The fixture is elevated at one end so that the rod members may be secured to the expanded sheet metal members simultaneously in a number of different positions. An auxiliary frame member may be employed whenever it is necessary to align the sheets vertically prior to being secured to the rod members.

Abstract: The hold down apparatus includes cooperating adjustable fences confining a workpiece for travel past a rotary cutter. A hold down assembly of the apparatus includes wheel members carried by a vertically adjustable crossmember. The crossmember is biased by multiple springs with the spring rate being variable by threaded components. A screw shaft additionally permits precise vertical adjustment of the hold down means. A rearwardly off set hold down wheel prevents tipping of lengthy workpieces. The fences have recessed areas to allow positioning closely adjacent and inwardly past the hold down devices.
