Abstract: A tool for extracting a glow plug includes an externally threaded shaft, an internally threaded sleeve that engages the externally threaded shaft, and a fixed cavity formed in one end of the externally threaded shaft. The cavity has a side entry to permit the insertion of the glow plug into the cavity in a direction normal to the shaft, and a pair of opposing shoulders integrally formed in opposing sidewalls of the cavity to engage the glow plug. The sleeve threads down the shaft until it contacts the engine block. Rotating the sleeve exerts a pulling force on the shaft, which is transferred to the inserted glow plug by the opposing shoulders in the cavity. This pulls both the shaft and the inserted glow plug away from the engine block.

Abstract: The specification describes economical lifting devices. A consumer jack comprising a rectangular base; a pair of connecting arms that are pivotally attached to the front end of the base, and a pair of lift arms that are attached to the connecting arms and attached at the rearward ends thereof to a sliding block. A screw-threaded actuator shaft is engaged with the sliding block to raise and lower a lifting pad attached to the forward ends of the lift arms of the device. The components are stamped from steel sheet and plate, and folded into the desired configuration, and assembled without the need for machining or welding. An economical power unit, for use with an economical jack stand and also for use with a lift bridge, comprises an adaptation of the consumer jack. The power unit does not use the lifting pad, but rather utilizes a pair of separated leveling pads pivotally attached to the forward ends of the lift arm for engagement with a lift collar of the jack stand.

Abstract: The hand tool for extracting bolts is a specialized marine oriented bolt extractor for use in extracting what are commonly called “Body Bound Bolts” from motor vessel shaft couplings. The body of the bolt extractor would be made of heavy duty steel and comprises a stationary flange and a moving flange. Located on the front side of the stationary flange are two cylindrical bolt housings for the bound bolts and two cylindrical extractor rod housings. The extractor rod housings pass through both flanges and house the 180 degree hook shaped extractor rods. One end of the extractor rods is secured to the moving flange with a washer and a nut, and the other end is placed against the bound bolts. A jack bolt passes through the moving flange such that the end of it is placed against the stationary flange. As the jack bolt is tightened, the moving flange moves away from the stationary flange and the extractor rods apply pressure to the bound bolts. This process is continued until the bolts are freed.

The holding member is releasably engaged with a pair of parallel elongate members. An actuator is connected to the elongate members and to a piston. A shaft damper is inserted into and temporarily held by the holding member. The holding member containing the shaft damper is inserted into a shaft a predetermined distance. The actuator then slidingly retracts the holding member while a pressing member at an end of the piston simultaneously holds the damper in the proper position in the shaft.

Abstract: A rotary clamp having a linkage assembly that provides an over-center condition for providing high actuation and clamping forces without excessively wearing the components of the linkage assembly. The linkage assembly is connected to a linear actuator for converting linear actuator motion into rotary clamp motion between a clamped position and an unclamped position. The linkage assembly provides a first link having an aperture for receiving a pin and a roller wherein the roller is coaxially connected o the pin. The second link is pivotally connected to the first link, and the third link is pivotally connected to the second link. The roller of the first link rollably engages a surface on the third link when moving in and out of the clamped position. A beam-like structure connected to the housing provides a wear surface wherein the pin engages the wear surface in response to the roller engaging the third link to prohibit the first link from reaching an over-center position.
