Abstract: A machine vise holds two parts against a center mounting block, and has simultaneously moving jaws slidable on a vise body toward opposite sides of the center jaw for clamping. One of the jaws is driven through a torque limiting clutch to the drive screw to provide a preload on one of the parts, after which the clutch releases for final, high pressure tightening.

Abstract: A power operated wrench for acuating the drawbars on machine tools, such as vertical spindle milling machines, which permits the operator to move a single handle, and after release of a safety interlock move a pneumatic wrench into position to engage the drawbar nut and either tighten or loosen the drawbar depending on the direction of motion of the operator handle. The mechanical operation permits the operator to rotate the operator handle in the same direction as would be done if the drawbar was being manually tightened or loosened, in order to tighten or loosen the drawbar under power. The safety interlock prevents movement of the power motor into engagement with the drawbar until the machine has been shut off.

Abstract: A carriage drive apparatus positions a carriage along a guide rail. First and second front drive rollers are rotatably mounted on a carriage drive housing on opposite sides of a nonrotating guide rail. The first and second front drive rollers are adapted to frictionally engage the guide rail. Third and fourth rear drive rollers are also mounted on the carriage drive housing on opposite sides of the guide rail. The third and fourth rear drive rollers are adapted to frictionally engage the guide rail. A motor is mounted on the carriage drive housing and is coupled to the front and rear drive rollers. The motor is used to drive the carriage drive housing along the guide rail. A sensor is used to sense the position of the carriage housing along the guide rail. The drive can be disengaged from the drive rail while the sensor remains engaged to permit teaching the controls various stop positions while manually moving the carriage drive housing.

Abstract: A robot assembly includes a support for mounting at least two arm portions and a wrist portion about an upright axis. The wrist has three axes of movement that are mutually perpendicular, and they are controlled by a single motor through an arrangement of electromagnetic clutches and gears so that one motor controls movement about all three axes of movement of the wrist. Additionally, gear drives are used for other movements on the robot arm to provide movement about seven independent axes in the arrangement shown with only two drive motors.

Abstract: A vise clamp has an elongated body which fits into a T-shaped slot of a tool table. The body has a head at one end which extends out of the slot and pair of pivotal lugs which fit under the side shoulder of the slot. Means are provided to provide a pivoting action which tends to pivot the head toward the table surface to tend to clamp a tool such as a vise against the table. The major portion of the clamp thus remains recessed below the table surface. The clamp permits making a low profile swivel base vise that has the clamps positioned below the vise base and yet they are easily operated.

Abstract: A combination vise that comprises a box construction frame that has three side surfaces for supporting the vise so that the jaws can be placed perpendicular to the table surface by laying the vise on either side and clamping it in position, or the jaws can be positioned on the top of the vise in a normal manner when the vise is set on its bottom.The three side surfaces of the vise which do not carry the jaws are machined so they will lay flat on a machine tool table and properly orient the jaws when the vise is clamped on any one of the three usable sides.

Abstract: A carving machine which has a tubular framework that allows easy attachment of one or more supplemental frames and additional carving spindles to the base frame. The length of the machine frame also can be extended very easily to accommodate longer workpieces. The carver includes individual motors driving the carving tools. The motors are mounted in housings provided with vacuum attachments for inducing a flow of cooling air for the individual motors. The housings also are sound deadened to reduce the noise level.

Abstract: A clamp effort intensifier that multiplies the manual effort used for clamping vise jaws onto a workpiece through the use of a cam that actuates the vise jaws together to provide adequate clamping forces while substantially reducing the manual effort necessary to achieve a safe clamp force. The effort intensifier acts to load the vise jaw through a heavy spring which deflects as the jaws are loaded. The amount of deflection can be used to indicate the clamping force exerted on the jaws. An interlock to the machine tool used will prevent operation of the tool until the clamp force exceeds a desired level.

Abstract: A carving machine which has universally movable multiple work spindles mounted on a frame, and movable along rails in a normal manner. The tracing station (the station which holds the pattern used in the carving operation) is located outboard of one lateral side of the rails, and outboard of the frame, so that a worker can easily trace on large patterns at the tracing station.

Abstract: A cutter for use on wood working tools such as for carving machines which is formed from a tubular segment cut along two planes which are nonparallel and nonperpendicular to the tube axis to provide cutting edges and adequate tool edge clearance, so that the rotating cutting tool can be moved axially along its rotational axis and cut cleanly in this direction as well while moving the tool in direction transverse to the rotational axis.

Abstract: A bench vise which incorporates a self locking fixed jaw operating with a pair of interlocking surfaces reacting as the fixed jaw is loaded. As the workpiece is tightened down, the jaw tends to be forced downwardly against the sliding portion of the vise to tightly lock the workpiece being held. The reaction of the load is carried directly into the support shaft for the fixed jaw, which also forms a swivel member for the vise.

Abstract: An adapter for converting a standard square headed bolt to a T-Bolt for use with machine tools for holding workpieces to the bed thereof. The adapter includes a fabrication having a capturing area formed by downwardly extending legs of the unit for receiving and retaining the head of a square headed bolt and having transversely directed elements above such capturing area to be received into the guide slot of the machine tool bed. The combination of the capturing area and the transverse elements, with an aperture to pass the shaft of the bolt from the capturing area, provides a means for retaining a square headed bolt within the T-Slot of a machine tool bed such that the same may be used as a tool or workpiece hold down device.

Abstract: A locking jaw machine vise which includes a fixed jaw rigidly mounted on a frame, and a movable jaw slidably mounted on ways or guides for movement toward and away from the fixed jaw. The sliding jaw is driven by an actuating nut and screw. The actuating nut has an inclined surface that interlocks with the sliding jaw to provide a downward force on the sliding jaw to prevent the sliding jaw from tilting when it is clamped. A set screw is provided on the device to limit the amount of movement of the movable jaw toward the actuating nut to minimize any tendency of the jaw and the nut to bind on the ways or guides used for the sliding jaw.

Abstract: A bolster table device for a punch press includes a reciprocable table positioned upon a support plate and movable along guideways. The support plate and table have inclined confronting planar surfaces which engage each other when the table is in a retracted position whereby the entire impact load exerted by the punch press is transferred to the support plate. The inclined confronting planar surfaces of the table and support plate are spaced from each other when the table is shifted towards and away from the retracted position. The bolster table is reciprocated by a closed hydraulic system which is operated by a driven cam device.
