Abstract: A screwdriver handle product and method of making same, where a solid core piece has an elastomer cover molded thereon, and the core piece has grooves for receiving the molten cover to thus have the cover secure on the core piece. The cover is shaped in cross-section to present corners, for enhancing the control and grip of the handle, and also the exterior of the cover is dimpled or of a roughened surface for further enhancement of grip of the handle.

Abstract: An animal collar having both elastic and flexible extendable and contractable characteristics and being made of a silicone rubber. The collar is of a serpentine shape which permits it to flex in the expansion and contraction of the circumference of the collar, and the elastic characteristic permits it to also expand and contract, all to accommodate the neck size of an animal and to support an identification tag.

Abstract: A vise for clamping workpieces of different sizes, and including two adjustable pieces, one of which gives a large adjustment and the other which gives a finer adjustment. A clamping jaw is included, and the adjustment pieces can be set so that there is desired clearance between the jaw and the workpiece prior to applying hydraulic force in the clamping action. Rotation restrictors apply to each of the rotationally adjustable members, and a spring returns the jaw to the unclamped or opened position.

Abstract: A vise having a base piece and an invertible V-block supported both laterally and downwardly on the base piece in either inverted position. A movable jaw operates toward and away from the V-block in distances in accord with the inverted position of the V-block, all to accommodate workpieces of different sizes and with only one invertible V-block which is snugly supported in lateral positions on the base piece and which is supported upwardly by shouldering on the base piece.

Abstract: A collet clamping mechanism having a sleeve with shoulders thereon, and an actuator for forcing against the shoulders for clamping a workpiece in the collet.

Abstract: A vise having a base portion and an upstanding tower thereon and with a movable jaw slidable on the upstanding tower by means of a control screw. Another screw is utilized to hold the upper jaw against the upstanding tower. A pair of V-blocks can be utilized for optimizing the range of utility with regard to sizes of workpieces.

Abstract: A collet clamp and releasing yoke apparatus having a support block and a cylindrical sleeve for receiving a collet. The collet is axially fixed, and the sleeve moves for contracting the collet to clamp a workpiece therein, and a yoke is employed for the clamping and releasing movement of the sleeve. A plurality of these assemblies can be positioned within the block so that a plurality of workpieces can be retained and worked upon.

Abstract: A multiple collet work-piece holder having a block with a plurality of openings and a collet retainer disposed within the openings. The retainer has pistons which are subjected to hydraulic pressure for moving the collet to a clamping position. The opposite ends of the collet are completely free from any obstructions, so the work-piece can be inserted from either end, and the collet is securely held against rotation so that the work-piece can be machined as desired. Also, an automatic release of the collet is provided, so that the work-piece can be released when fluid pressure is relieved.

Abstract: A deburring machine which includes a power means and a rotating cutter plate adjacent a fixture which holds a work piece with a burr on the end. The cutter plate has a circular cutting opening therein which rotates past the work piece to remove the burr, and there can be a circular row of the cutting holes in the plate.
