Abstract: A method and apparatus for pulling multiple joints of pie which comprises a pulling section and a pulled section, the method and apparatus working while the joints of pipe are below grade and capable of pulling multiple joints of pipe without relocating the pulling section.

Abstract: A quick-release vise utilizing one or more clamp shafts that can be easily re-configured to clamp with CW or CCW rotation of a clamp handle. The clamp shaft is received in a housing secured to the underside of a workbench, and is free to slide in and out. The clamp shaft passes through aligned holes in a pair of opposing jaws, at least one of which is moveable. A pinion freely slides on the clamp shaft within the housing and converts rotational movement from the clamp shaft into linear movement via a meshing rack gear. The linear motion actuates a bridge which slides against a laterally fixed wedge causing the bridge to displace a locking element which clutches and moves the clamp shaft to affect clamping between the jaws. The wedge and bridge pair can be inverted to allow clamping to occur with a either CW or CCW rotation of the clamp handle and/or re-oriented to cause a spreading motion between the jaws rather than a clamping motion.

Abstract: A clamping assembly to hold a woodworking knife in place in a woodworking machine. The clamping assembly comprises a clamping component comprising a body and an actuator. The body has three discrete contact positions distributed thereon: 1) a fulcrum located generally at one end, 2) a knife abutting portion located generally at the other end, and 3) a bearing surface located elsewhere. The actuator is for applying a clamping force to the body along a clamping axis located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis. The bearing surface is a surface wherein a line normal to the bearing surface intersects the line normal to the fulcrum at a position outside of the clamping component at a location farther askew of the clamping axis than the fulcrum.

Abstract: A clamp for quickly, effectively and safely removing a cathode collar from an HDP deposition chamber for routine maintenance, cleaning or replacement of the collar. The clamp includes a pair of clamp plates which are capable of pivoting movement on respective ends of a connecting rod. A clamp shoe for gripping a corresponding edge of the annular collar is provided on the bottom end of each clamp plate, and a turnbuckle is fitted with a pair of threaded shafts which engage the upper end portions of the respective clamp plates. By rotating the turnbuckle, the threaded shafts are advanced away from each other against the clamp plates, which pivot on the connecting rod and cause the clamp shoes to tightly engage respective edges of the collar. The clamp is grasped to lift the collar from the chamber and replace the collar in the chamber after cleaning or maintenance.

Abstract: A throttle pedal depressor for a vehicle includes an adjustable hook and locking plate for maintaining the hook in a fixed position on a shaft. A rubber tip is provided at one end of the shaft for engaging a pedal and a screw assembly is rotatably adjustable to provide fine adjustment.

Abstract: A slide bar clamp having a straight surface on an elongated base that can serve as a straight edge. The base includes a longitudinal channel in which a rod is suspended. A first clamp surface is fixed at one end of the base. A moveable lock and clamp structure is mounted for longitudinal movement within the channel back and forth along the rod. The lock and clamp structure is formed in a housing. A handle is rotatably mounted on the housing. The handle locks by forcing an increasingly widened portion against a plurality of lock plates. The lock plates are arranged face-to-face and each has a hole through which the rod is inserted. In the locked position, the lock plates are tilted such that the inner edges of their holes grab the rod to prevent movement of the lock and clamp structure away from the fixed clamp surface. The slide bar clamp has a flat surface which permits mounting of the slide bar clamp on an adjacent flat surface or the back of an adjacent clamp.

Abstract: A work holding device is disclosed which has a fixed jaw and a movable jaw mounted on a pair of parallel guide rods for guiding the movable jaw toward and away from the fixed jaw. For moving and actuating the movable jaw, the guide rods are engaged by a handle operated cam member with a self-energizing frictional locking action responsive to handle movement.

Abstract: A clamping fixture slides between a pair of guide rails and includes a pressure plate between the guide rails. Lock plates with internal openings for receiving the guide rails are held captive on the pressure plate. An operating bar with stepped ends, one adjacent each locking plate, is deflected by a cam mechanism to incline the lock plates relative to the guide rails, thus wedging the lock plates to prevent further sliding along the guide rails. Return springs are provided to urge the lock plates to an unlocked position when pressure on the operating bar is released. A mixing apparatus using the clamping fixture is also disclosed.

Abstract: A fast acting and adjustable vise is disclosed herein having an elongated base movably supporting a pair of jaws adjustable between opposing holding surfaces for releasably supporting small parts or workpieces. Manually rotatable wheels are operably coupled to each jaw for independent and separate movement along a linear path and a universal mounting device adjustably supports the vise on a supporting surface. In one form, one jaw of the pair includes a finger-operated resilient clamp for selectively and rapidly positioning the clamp to a desired location on the base.

Abstract: A compound clamp comprises a first clamping component defining a plane and having a clamping arrangement presenting a force along a first clamping axis in that plane and a second clamping component having a second clamping axis, the second clamping axis being perpendicular to the second clamping axis. The clamp also includes a further arrangement for attaching the second clamping component to the first clamping component so that the second clamping axis is in the plane of the first clamping component and is translationally adjustable along the first clamping axis independent of the clamping arrangement of the first clamping component.

Abstract: Clamping apparatus for clamping a work piece onto a work table remote from the edges of the work table. Apparatus includes a main support member and first and second engaging members spaced along and extending from the support member so that outer ends of the engaging members cooperate with the work table. Jacking apparatus cooperates with one of the engaging members to move the engaging member relative to the support member. This clamps the work piece onto the work table with a clamping surface associated with the main support item. Each engaging means can be quickly adjusted to accommodate work pieces and work tables of different depths. The clamping surface can be resiliently mounted relative to the support member to increase versatility of clamping apparatus.

Abstract: A tool capable of applying clamping forces or, alternatively, spreading forces to the surfaces of spaced apart articles. The tool includes an elongate tubular base at one end of which is removably mounted a tail stop which serves to impart both clamping and spreading forces to associated articles. Mounted at the opposite end of the tubular base is a boss which is internally threaded to receive the screw shaft of a traveler assembly. The traveler assembly includes oppositely disposed, force imparting members which coact with the tail stop in clamping and spreading operations. Movement is imparted to the traveler assembly by a ratchet wrench on the screw shaft. The traveler assembly may be additionally supported by a telescopic member in slidable engagement with the tubular base of the tool.

Abstract: A vise to hold a pair of skis in either the flat or edge up positions employs two spaced base members, a pair of guide-ways and a clamping rod extending between the base members. A floating jaw slides along the guideways and a movable clamping jaw is side actuated to grip the clamping rod to hold the skis in a snug and firm condition.
