Abstract: A reversible pulling apparatus including multiple reversible jaw members pivotally attached to a first yoke having a pressure screw extending therethrough. A second yoke is axially extendable from the first yoke and includes the cam members coactive with a cam surface defined at the outside ends of the jaw members to positively engage the jaw members at a fixed diameter of the part being subjected to an inside or outside pull.

Abstract: A bit construction for use in restricted work spaces includes a preformed cap member having a center axial counterbore for receipt of cylindrical bit member having a shaped end that projects outwardly from the cap member and defines a bit for engaging a fastener and acting as a driver. A specific brazing operation enables assembly of the component parts to provide a useful bit construction.

Abstract: A reversible hand pliers provides for movement of the jaws of the pliers in the same direction as the movement of the hand grips or in the opposite direction depending upon the manner in which the separate handles are engaged with the separately moveable jaws. The handles are substantially identical in construction as are the jaws. Pivoting of the handles with respect to the jaws is effected by movement of the handles from a coplanar position on one side of the jaws through approximately a 180.degree. rotation to a coplanar position on the opposite side of the jaws.

Abstract: A unitary molded tool for decoupling telescoping tubular members includes two companion spring engaging sectors joined along one longitudinal edge by a collar which has a greater radius than the sectors and which is attached to the separate sectors by spaced rib members.

Abstract: An improved mechanic's creeper includes a closed loop, unitary metal frame supported by heavy duty casters recessed at spaced intervals in the frame. The frame is comprised of a single, closed loop rectangular shape, and a single cross member attached to opposite sides of the frame to assist in support of a platform. The creeper is thus configured to define a low profile while minimizing any obstructions to the user's field of motion.

Abstract: A hood prop or support tubes two or more telescoping tubular members which are locked together by means of a plate retained within the larger diameter tubular member that is biased by one of the bearing supports for the inner tubular member, and which may be manually released by pushing the plate by the biasing force of the spring.

Abstract: An oil filter removal tool for removing an oil filter contained within the oil pan of an internal combustion engine is disclosed. The tool has a pair of outwardly engaging jaws, a rotatable central socket drive element, means for connecting the outwardly engaging jaws to cooperatively engage the central socket drive element, and means for outwardly biasing the jaws. The outwardly engaging jaws each have a substantially semicircular outer wall which has means for engaging an oil pan filter cap. The outwardly engaging jaws each further have an inner wall which has a central polygonal surface and retaining means for retaining the central socket drive element within the jaws. The central socket drive element has an upper portion and a lower polygonal base which has a plurality of drive walls.

Abstract: An automotive separating tool that is used for separating ball joint connections, tie rods from steering arms, and other similar parts and that has wedge shaped head, with a pair of projecting prongs, and a handle. The head and handle are removably secured together by a threaded connection so that different sized heads may be used either with a handle designed to be struck by a hammer or with a handle designed to be driven by a conventional air hammer.

Abstract: A front wheel axle pulling tool includes a clamp secured to a flexible cable and a slider hammer secured to the flexible cable by a slide nut.

Abstract: A circuit tester is described herein and includes a housing closed by a removable cap member. An electrode, or wire contact, extends through the cap member and electrically interconnects with a bulb, fitted within the housing. The electrode carries a spring-biased catch member which is used to select and capture the wire under investigation.

Abstract: A tool to remove the universal joint boot of a front wheel drive vehicle is disclosed. The tool includes a U-shaped yoke and two differently sized split rings which are individually secured to the U-shaped yoke. The tool further includes a driver attachment affixedly attached to the yoke to accommodate an air hammer.

Abstract: A pliers type tool useful for removing and replacing bearings of a Rzeppa or constant velocity type universal joint includes a pair of separable jaws connected with translatable links of a hand tool. The jaws are inserted into the hub of the joint, spread and then the entire hub assembly is pivoted in order to expose the bearings sequentially for removal thereof or replacement thereof in the joint.

Abstract: Pneumatic impact hammer for driving a frost plug into an engine block. The hammer includes a port for interconnection to a supply of compressed air, a chamber, a trigger, an elongate tube, a mallet slidably mounted within the tube, and a driver extending from one end of the tube. Compressed air is received by the chamber. Upon depressing the trigger, the compressed air within the chamber is substantially instantaneously applied to the back of the mallet. Consequently, the mallet is driven down the length of the tube toward the driver. The mallet impacts against the driver which, in turn, drives the frost plug into the engine.

Abstract: Cable lubricator tool for lubricating a drive cable of a speedometer includes an adapter for attachment to the speedometer cable housing, a drive shaft extending through the adapter and connectable to the cable; a lubricant reservoir connected with an annular chamber surrounding the drive shaft. The lubricant chamber may be pressurized forcing lubricant through the annular chamber into the cable housing while the drive shaft may be rotated to effectively rotate the cable as lubricant is being forced into the housing surrounding the cable.

Abstract: An improved battery post and terminal cleaner is comprised of at least two longitudinal blade members each having an outside scraping surface on one end and an inside scraping surface at the opposite end. The blade members are housed in a body member in which they slide in unison to adjust the spacing of the ends of the blade members to accomodate variously sized terminals openings and posts.

Abstract: A valve seat forming tool includes a pilot rod that may be inserted into the valve rod opening of an engine block. A cutter assembly including a pair of cutter blades projecting radially outwardly from the assembly is rotatably positioned on the rod and may be rotated to cause the cutter blades to engage and resurface a valve seat. The tool may be placed in a calibration block to calibrate blade position. Subsequent to calibration, the assembly is positioned over a valve seat of an engine block. The cutter blades are then radially adjustable by means of a micrometer and subsequent to adjustment the cutter blades are rotated manually to cause the blades to reform the surface of the valve seat.

Abstract: A tool for cutting or reaming a counterbore in a workpiece is guided by a pilot member secured in a bore. The tool includes a rotatable blade holder having a plurality of attached cutter blades. One of the cutter blades has a lateral cutting edge at a pre-selected radial distance from the rotational axis of the blade holder. The remaining cutter blades do not include lateral cutting edges. Consequently, the lateral or diametral dimension of the counterbore is defined by a single blade. This arrangement substantially prevents oversizing of the counterbore.
