Abstract: A tool for inserting O-rings into a recess provided in a bore in a part comprises a cylindrical housing having a cylindrical O-ring stripper rigid therewith and projecting from one end thereof. A plunger is reciprocably mounted within the housing for movement along its axis from a resiliently balanced, equilibrium position. An O-ring holder includes a pair of bars pivotally coupled to one end of the plunger and projecting from the housing through a notch dividing the stripper into two halves. The holder bars are each provided with a notch or jaw, with the latter being spaced for gripping an O-ring at diametrically opposite locations. An O-ring guide is reciprocably mounted to the plunger and extends between the two holder bars. A spring normally holds the guide for movement with the plunger but permits the guide to retract within the plunger when an O-ring is being picked up by the holder bars.

Abstract: A torque limiting wrench is provided having an input member and an output member coupled to each other so as to limit the transmitted torque therebetween. The coupling is provided by spring rods supported in the output member surrounding the input member, the spring rods being arranged along a pitch circle disposed concentric with respect to the input member and, in the tension-free state, disposed within the zone of axial catches arranged on the circumference of a collar provided on the input member. When a sufficient input torque is admitted, the spring rods are bent outwardly by the flanks of the catches and out of the range of the catches when the predetermined torque is reached.

Abstract: An improved cork screw which comprises a rotary handle and a cork penetrating spiral member encased in an upper hollow shank and a lower bell-shaped pedestal which can be seated on a bottle. A cork pulling lever is attached to the top of the spiral member and threaded through two diametrically opposite longitudinal apertures provided in the wall of the hollow shank. It is separably fitted to the bottom side of the handle and movable upward or downward along the longitudinal apertures. When the cork is to be pulled out, the user may hold the handle with his one hand and pull the lever towards the handle with his two fingers, thereby facilitating the cork's removal.

Abstract: With a cork screw having a bell-shaped housing with which a cork can be lifted out of the neck of a bottle without reversing the turning direction of the cork-screw blade and which is provided with a sleeve-like body with which the cork screw is firmly put on the neck of the bottle to be uncorked in order to lift out the cork, the lifting of the cork out of the bottle to be uncorked is often made difficult because the cork-screw blade is not centered. In order to avoid this disadvantage, there is guided in the sleeve-like body a spring-loaded piston which is located near the lower end of the sleeve-like body when the cork-screw blade is driven into the cork and through which the cork-screw blade passes centrally with a slight clearance.

Abstract: Apparatus for unthreading collars from casing and tubing or the like employed in bore holes, and including a chuck adaptor to be mounted on a lathe. The chuck adaptor has a shaft which is held by the chuck of the lathe. The shaft carries the housing in which three eccentrically apertured contiguous rings are mounted. The center ring is rotatable in the housing whereas the two other rings are fixed therein. A slot is provided through the housing at the position of the center ring. A handle-like projection extends from the exterior of the housing through the slot and is threaded into the rotatable ring. Gripping dies are carried internally of the rotatable ring. The fixed rings hold the collar while the center ring is rotated by rotating the projection to cause the gripping dies to seize upon the collar. The lathe turns the adaptor while a wrench engaged with the pipe threaded to the collar may be held stationary. The center ring is turned about an axis which is eccentric to that of the aperture therethrough.

Abstract: A power driven stud tensioner device which connects to an engaging member integral with or connected to a stud to be placed in tension after which a nut on the stud is tightened. The device for placing the stud in tension is a cam actuated clamping assembly having a plurality of layers wherein motion of one component translates into a different motion in another component. The device includes a helically slotted actuating sleeve which receives cam pins passing through an axially slotted stationary ring which are then received in one of two inner camming rings which are axially shifted by the pins in response to rotation of the sleeve. Rotation of the actuating sleeve, which is driven externally by a power drive including a gear assembly connected to the sleeve, will cause the camming rings to move into and out of engagement with cam followers formed on, or attached to, a four segmented clamp which is thus moved into, and out of, locking engagement with the engaging member.

Abstract: A torque wrench having a reaction bar and an arm extending laterally in the same direction from a work engaging head. The arm is flexed in response to torque applied to the head through the bar and cooperable members on the bar and arm respectively engage as a consequence of that flexing. The member on the bar is a pivoted lever which responds to the aforementioned engagement to swing towards a signal generating position at which it causes a switch to operate to close a circuit contained within a handle part of the bar. The circuit includes audible and visible signal means and those means are energized while the circuit remains closed. The switch is normally urged towards a circuit closed position but is prevented from reaching that position by a blocking member, and the aforementioned pivoted lever renders that blocking member inoperative when the pivoted lever is swung into its signal generating position.
