Abstract: A tool for use with a tool holder has a body to which at least one blade such as a circular saw blade or milling cutter is clamped to prevent the blade from turning when a selected tooth is brought into cutting or grooving contact with a rotating work piece, the body of the tool has first and second parallel clamping surfaces through which a diametric slot opens. A first clamping member has a hub on which a blade is rotatably mounted and which fits the slot and is held thereby against turning. The two clamping members are connected by a threaded member by which the clamping members are drawn towards each other to clamp the blade against the first clamping surface. A member threaded radially through the body extends into the slot and is operable to move the hub radially with respect to the center thereof enabling positions of a tooth relative to the work piece to be precisely established. When more than one blade is mounted on the hub, the blades are held apart by a spacer.

Abstract: This application discloses an improvement for a conventional open-end adjustable wrench comprising a recess in the movable jaw of the wrench adapted to receive the first end of a chain. Spring biasing means on the first end of the chain to releasably retain the first end of the chain in the recess and a curved lip on the fixed jaw adapted to receive and retain the opposite second end of the chain are also disclosed. Finally, a ratchet-like motion achieved by the modified wrench is disclosed wherein the work object is engaged in a non-slip manner during the movement of the wrench handle in one direction, and in a slipping manner during the movement of the wrench handle in the opposite direction. The unique refined feature of maximum adjustment provided by the flexible movement of the wrench jaw being repositioned where the knurl is moved allows the full ratchet-like action motion to be applied to the work object.

Abstract: A coaxial cable stripping tool has a pair of opposing jaws which include a stripping jaw and a clamping jaw supported as associated ends of a pair of pivotally moveable operating handles. The stripping jaw has a pair of spaced apart cutting and stripping blades for cutting axially spaced portions of a cable to be stripped when the cable is gripped by the jaws and the tool is rotated about the axis of the cable. The jaws are normally spring biased to closed position and move to open position in response to operation of the handles. A clean-out member mounted on one of the handles sweeps through the space between the blades to dislodge scrap material trapped between the blades each time the handles are operated to open the jaws.

Abstract: A cyclic crimping mechanism for producing coherent plural-layer food products from food assemblies, each food assembly including a bottom patty covered by a top patty (other patties, food slices, or condiments are usually positioned between the top and bottom patties), uses a cyclically, intermittently actuated conveyor to locate each food assembly at a crimping position for a predetermined crimping interval; in sequence, a confinement tool is moved down to an actuated position to define peripheral limits for the food product, a tamping tool is pressed down onto the food assembly to reduce air entrapment, and a crimping tool presses the periphery of the top patty into the bottom patty to seal them together in a coherent food product, after which these tools are all elevated to rest positions clear of the crimping position and the conveyor operates to move the finished food product away and position a new food assembly at the crimping position to start the crimping cycle anew.

Abstract: An improved cutter disk for machining rotating workpieces, and in particular an improvement in such cutters useful in monotonic-type cutters in which the tool inserts carried on the disk are mounted in such a manner as to present the inserts to the workpiece at a radical lead angle, optimally on the order of 60 degrees. The tool inserts are preferably carried on both sides of a V-shaped edge on the cutter disk. Chip gullets are formed in the disk parallel to the tool inserts and are angled with respect to the plane of the disk. This optimizes the space for chip gullets and allows either a doubling of the feed rate for a given chip thickness and insert density, or a reduction in chip thickness by 50% for a given feed rate. The invention also results in the optimal use of space for the chosen insert density, especially on narrow cutters, and permits an improvement in the pocket strength and insert strength, as well as improving tool life.

Abstract: In a remaining bar material machining method, a plurality of works are taken from a continuous bar material on an NC lathe, and the remaining portion left at the end of the bar material is machined effectively. In the lathe in which both first and second headstocks are axially movable along the bed, the continuous bar material can be continuously machined with efficiency. At that time, to utilize the remaining portion left at the end of the bar material effectively without discarding it, this remaining bar material is transferred to the second headstock. An NC controller includes a main machining program and a remaining bar material machining program; when the remaining bar material has been transferred to the second headstock, the remaining bar material machining program is executed instead of the main machining program having hitherto been executed. During machining the remaining bar material on the second headstock, the first headstock is waiting in readiness for the machining of the next bar material.
