Abstract: A grasping device comprises a grasping member springably connected to a handle member. When the grasping member is withdrawn from the handle member, plier arms on the grasping member open so that an object to be grasped may be positioned therebetween. When the grasping member is permitted to be pulled by the spring back into the handle member, the plier arms close about the object, grasping it securely.

Abstract: A tool for forming a high strength reinforcing bar coupling driving self-locking wedge sleeves over each end of a contractible jaw assembly bridging the abutting ends of the bar to be joined. The sleeves are seated in collars engaged by the distal ends of arms driven for closure by a piston-cylinder power unit and a cam on at least one arm. In one form the cam on one arm is engaged by a roller connected by a tension link to the other arm. In another form cams are provided on each arm driven by rollers fixed with respect to each other. The collars include self-releasing collets seating the sleeves. The tool has other uses such as bar shearing or forming.

Abstract: Clamping pliers includes a first handle with a first jaw, a second handle, a separate second jaw all of which are pivotally connected to a pivot to affect pivoting about the same pivot point. A connecting link connects the second jaw with camways defined in the first and second handles. A pin extending from the link engages the camways and upon closure of the handles provides a clamping action.

Abstract: A manually-operable surgical tool, suitable for laparoscopic operations, has separable parts which cooperate to move a pair of end effector elements which can be readily replaced by another pair of end effector elements. A handle portion enables controlled longitudinal movement of an elongate inner element relative to an outer surrounding tubular element. The tubular element has a distal end with a first cleft and a pair of parallel cantilevered inwardly-oriented opposed cam pins. The distal end of the elongate inner element is provided with a second cleft and a transverse force-application pin. The selected end effector elements rotatably fit inside the cleft of the inner element to receive an applied force via the force-application pin. Each end effector element has a blind-ended cutout having an open end for engaging at least with a corresponding one of the cam pins.

Abstract: An improved set of adjustable locking pliers having two pivotally mounted jaws. A lock lever is pivotally mounted to one handle member and slidably retained in the longitudinal grooved portion of the opposite handle, and an adjustment screw threaded longitudinally into the grooved handle member bears upon the sliding end of the lever. Handle members are pivotally connected to retaining plates, said plates having a pin projecting between them with the jaws pivotally mounted and laterally disposed thereon. The gripping surfaces of the jaws interlock above the pin and meet flush in the locked position. The handle member having the adjustment screw has a curved end which spreads the bottom of the jaws apart in the locked position, thereby forcing the gripping surfaces together.

Abstract: There is provided a new and useful combination of a bottle stopper and stopper-remover comprising cylindrical stopper means (10) of resilient material, the stopper means (10) having top, bottom and side surfaces and a deep well (14) extending into the stopper (10) from the top surface (16); a hollow sleeve (30) in and substantially conforming in cross-section to the well (14), the sleeve (30) having top and bottom ends and inner and outer surfaces; a series of protruding interference members (36) on the outer surface, at least one detent member (46) on the inner surface (43,44) spaced a predetermined distance from the top and bottom; a pair of openings (47) through opposite sides of the sleeve (30) adjacent the detent (46) on a side of the detent (46) remote from the top end; a pair of longitudinal slits (45) extending from respective ones of said openings (47) to a position spaced from said top end; and puller means (50) for insertion into the sleeve (30), the puller means (30) comprising a top gripper membe

Abstract: The tool 10 of the present invention includes in its mid-portion a handle or gripping portion 12. Extending outwardly in opposite directions from the gripping portion are a pair of spaced transition portions 14 and 16 each respectively terminating in a pair of tapered portions 18 and 19. The tapered portions 18 and 19 extend to a box engagement portion at each end 20 and 22. Each box engagement portion includes a transversely extending tapered portion 24 and 26 each of which terminates in a respective edge 28 and 29, and respective hook portions 30 and 32. It will be apparent that the transverse portion 20 is smaller than the transverse portion 22 to allow opening of smaller boxes with the end where transverse portion 20 is located.

Abstract: To permit the connection of an electric cable (12) in an end element (10) having a partly frustum-shaped outer surface, a crimping tool is proposed incorporating a gripping plier (50) and a crimping die (60). When the element (10) to be crimped has Been placed in a recess (48), an actuation of the tool has the effect of the element (10) being gripped by the plier (50), the closure of the die (60) and then the application of a tension to the end element by said plier (50), so as to make the die pass through said element. The die (60) then opens automatically and remains open until the tool has returned to the inoperative position.

Abstract: A tool for closing and clearing the tip of a caulking tube includes a shaft, barbs on the shaft and a blade guide and hardened caulk cutting groove extending along the shaft.

Abstract: A ligator device has handles which are linked to a center slide to make the same move rearwardly when the handles are squeezed together. A pair of jaws surround the front of the slide top and bottom and are connected to it so as to open when the handles are released and close when the handles are squeezed. The forward ends of the jaws carry anvils which, when closed, squeeze ligating clips shut which are supplied from a magazine.

Abstract: A crimping tool includes at least three crimping jaws guided for displacement in a tool body. The jaws present first, second and third straight jaw surfaces, wherewith the first jaw surfaces together define a crimping opening. The first jaw surface on each jaw is constantly in slidable abutment with the second jaw surface of an adjacent jaw. The third jaw surfaces abut against and are movable along a respective straight guide surface formed in the tool body. These guide surfaces or extensions thereof define, when projected onto a plane extending at right angles to all guide surfaces, a polygon having the same number of sides as there are jaws present. The first, second and third jaw surfaces of each jaw or their extensions define a triangle, when projected onto said plane.

Abstract: A surgical needle holder is provided in which the handle members are arranged in a plane at right angles to associated jaws which are operated by the handles. A camming arrangement is coupled between the handles and jaws to convert the movement of the handles in one plane to movement of the jaws in a second perpendicularly arranged plane. The needle holder is employed for suturing in surgical procedures and facilitates placement of the hand of the operator as well as the application of force in a rotary sense thereby.

Abstract: A pliers-type hand tool has a pair of pivotally connected jaw-forming members defining jaw portions on one side of the pivot connection and elongate slotted lever portions on the other side of the pivot connection. A slide pin is received in the lever portion slots and is connected by pivot links to operating handles which are attached to the pivot connection in common with the jaw-forming members. The arrangement produces a mechanical advantage between the handles and the jaw-forming members allowing a greater jaw-closing force to be developed, related to the manual effort applied to the handles, than with conventional pliers-type tools of comparable size.

Abstract: A lever wrench for the assembly and disassembly of snap fit valves having a first lever arm substantially linear in shape, the first lever arm having a handle end and a contact end with a punch pin removably secured to the contact end, a second lever arm rotatably mounted to the first lever arm and including a first leg and a second leg, the first leg having a plurality of depending contact points in alignment with the punch pin of the first lever arm, a third lever arm rotatably secured to the second leg of the second lever arm and comprising a handle secured to a disk whereby rotation of the third lever arm causes the first lever arm to rotate with respect to the second lever arm thereby causing the punch pin to cooperate with the contact points for the assembly and disassembly of the snap fit valve.

Abstract: Crimping tongs in particular for crimping a sleeve on a cable, said tongs having jaws coupled to each other so that one moves relatively to the other, a cam (15) driven by a ratchet wheel (16) which actuates a toggle joint device (20,21,22) a catch being installed on the moving handle (13) so as to drive the ratchet wheel step by step by moving the moving handle, the toggle joint device making the moving jaw (12) rotate in the closing direction. With a view to axial crimping, the moving jaw (12) has a moving die (14) which moves rectilinearly. A spring (25) biases the toggle joint to move the one jaw toward the other, and a trigger (19) is pressed to open the jaws sufficiently for insertion of a sleeve to be crimped. Releasing the trigger causes the jaws to hold the sleeve under the action of spring (25); so that the crimping action can be performed with one hand.

Abstract: A tool with a body member which can be braced between the engine block and an adjacent wall of the automobile has a sharp-pointed member movable under the control of a hand operated lever arm to penetrate a freeze plug in the engine block and become wedged in the plug so on reverse movement of the lever arm the plug is removed from the engine block. For use in inserting a new plug, the sharp-pointed member is replaced by a flat headed one which drives a new freeze plug into the appropriate block opening on appropriate operation of the lever arm.
