Abstract: An instrument for engaging a bearing configured to facilitate articulation of a femoral component and a tibial component. The instrument includes a first bearing engaging portion configured to engage a first end of the bearing, and a second bearing engaging portion configured to engage a second end of the bearing that is opposite to the first end. A coupling member of the instrument interconnects the first and the second bearing engaging portions. The coupling member is operable to move the second bearing engaging portion relative to the first bearing engaging portion to secure the bearing therebetween.

Abstract: A framing hammer assembly enables a user to tend to nail work within tight spaces. The hammer assembly comprises a three-dimensional hammer head, an elongate hammer handle, and a select tool attachment assembly. The hammer head comprises first and second nail-striking heads, a fulcrum, and a nail-pulling claw. The first nail-striking head and the second nail-striking head are orthogonally situated relative to one another for enabling a user to drive nails within tight spaces. The hammer handle comprises a head-engagement portion, a second handle end, and a hand-grip portion. The select tool attachment assembly comprises a select tool accessory and certain fastening structure for fastening the select tool accessory to the second handle end. The select tool accessory is interchangeable with a plurality of secondary tool accessories for selectively providing a lever arm and for enabling the user to remove driven nails or similar other hardware within tight spaces.

Abstract: A wrench includes a wrench head mounted on an end of a handle. A handle of the wrench includes a fixed portion and a rotatable portion. Rotation of the rotatable portion of the handle causes movement of at least one contact surface of the wrench head. In one embodiment, rotation of the rotatable portion provides adjustment or movement of one of the jaws of the wrench head relative to another jaw of the wrench head. In another embodiment, rotation of the rotatable portion provides rotation of the wrench head. The rotatable portion of the handle is slidably mounted within the fixed portion of the handle, such that rotatable portion can be selectively extended to provide additional leverage on the wrench.

Abstract: A bi-directional adjustable spanner with a driving roller comprises a head and a handle. The head includes a movable jaw slidably received within a sliding groove of the head; an adjustable sliding rod; a retaining jaw and a driving roller. The retaining jaw haS a receiving chamber; one side of the receiving chamber having an opening facing the movable jaw. The receiving chamber has a straight receiving groove with a U shape end; the receiving chamber being communicated to the straight receiving groove. The driving roller is received in the receiving chamber of the retaining jaw; and a part of the driving roller protruding out of the opening of the receiving chamber towards the movable jaw. An elastomer is received within the receiving groove. A resisting pin of the elastomer resists against the driving roller. A cover sheet is screwed to the opening of the retaining jaw by a screw.

Rotation of the rotatable portion of the handle causes movement of at least one contact surface of the wrench head. In one embodiment, rotation of the rotatable portion provides adjustment or movement of one of the jaws of the wrench head relative to another jaw of the wrench head. In another embodiment, rotation of the rotatable portion provides rotation of the wrench head. The rotatable portion of the handle is slidably mounted within the fixed portion of the handle, such that rotatable portion can be selectively extended to provide additional leverage on the wrench.

Abstract: A wrench includes a tubular extension secured in the second jaw member by set screws. The tubular extension is connected on one side by the adjusting handle and is connected to the bored gear on the second side. When the handle is rotated, the internally threaded gear drives first jaw portion in and out and is also exposed for conventional hand adjustment.

Abstract: An adjustable wrench has a slotted body member and a handle threaded into a bore in a body member stem and protruding into one end of the slot. A movable jaw piece is rotatably mounted to the protruding handle end and slidable in the slot. A pair of angled fixed jaw faces is formed at the far end of the slot, while corresponding jaw faces are formed on the movable jaw piece. Relative rotation of the handle and body member causes relative advance or retraction of the movable jaw piece in the slot to adjust the spacing between the sets of jaw faces to fit the wrench to bolt heads or nuts of various sizes. The structural support afforded by the handle-movable jaw piece connection enables low cost construction and compact structure allowing greater accessibility to recessed bolt heads and nuts. A locking rod extends within the handle in some embodiments, with a locking knob at the remote handle able to be tightened to hold an adjusted position.

Abstract: A fireman's personal hand tool is comprised of a spike member and a wrench member. Both members may be used in combination as a slide hammer with the spike member being hammered by the wrench member between objects to be pried apart. The wrench member may also be used to open or close valves and is configured to fit a variety of hydrant valve head shapes and sizes. Both the spike member and the wrench member have integral hose coupling jaws to engage and disengage hose couplings. The members are separable so that the jaws may be used independently or in combination. In addition, there are three different sizes of jaws to enable the tool to fit a greater variety of coupling sizes.

Abstract: A tool holder for holding a chisel or the like includes a fixed jaw member, generally in the shape of the letter C, wherein one arm of the C has an apex communicating with the center of the C and the other arm thereof defines a threaded aperture whose longitudinal axis intersects the apex and a threaded shaft is adapted to travel and threadingly mate with the threaded aperture to bear against the perimeter of a tool that is circular or hexagonal and to urge the tool against the apex, the arms defining a channel or space therein which acts as a sighting channel for the user, on the one hand, and a passageway for easy removal and insertion of the tool, on the other hand. The threaded shaft extends into a resilient handle that absorbs shock.

Abstract: An adjustable wrench particularly useful to facilitate ease of installation and removal of fluid fittings in and from a fluid system. The wrench includes an elongated handle threadedly cooperating with a body member. The body member has a pair of opposed clamping faces defining a clamping cavity adapted to receive an associated fitting. Relative rotation between the handle and body portion axially advances and retracts a smooth end face of the handle into and out of abutting engagement with a side wall of the fitting. A cutout region in the wrench body is adapted to receive one branch of an associated tee or cross type fluid fitting. The subject wrench readily facilitates clamping engagement of a fitting while coupling nuts are run up on or backed off of the fitting branches by conventional means.

Abstract: A screw cap removing and tightening device comprises: an elongate plate member formed to provide a front gripping member at its front end, a plurality of longitudinally equal spaced teeth members in the intermediate portion, a cylindrical channel member at its rear end, and a slightly slopped downward member connecting the intermediate portion and the rear end; surrounding means which substantially surrounds the intermediate portion of the elongate plate member and is slidably movable along the elongate plate member; locking means movably secured to the surrounding means for preventing a rearward movement of the surrounding means; a rear gripping member supported and confined by the surrounding means; and rotating and twisting means contained by the cylindrical channel member and engaged with the surrounding means.
