  • Patent number: 4977660
    Abstract: A tool for removing a coupling cap when disconnecting the universal joint from a yoke, and installing a coupling cap when connecting a universal joint to a yoke. The tool includes a pair of anvils spaced apart for supporting the universal joint and yoke in a fixed vertical position. When the tool is used for disconnecting the U-joint, a rod is provided including a bottom end having an outer lip encircling the mouth of a bore extending inward therefrom. The lip impacts the portion of the yoke circumscribing the opening containing the cap in press fit association with the U-joint and the yoke in response to a downward force acting on the rod, to cause the cap to dislodge from the opening and move upward into the bore of the rod. When the tool is used for connecting the U-joint to the yoke, the rod is provided including a piston at the bottom end thereof.

  • Patent number: 4694569
    Abstract: A bearing extractor having a support element in which a rod is positioned such that the rod is capable of expanding, within a bearing, the prongs of a bearing grasping assembly. Once the prongs of the bearing grasping assembly grasp the bearing, the bearing is raised by the rod until the case surrounding the bearing engages the support element. Thereafter continued raising of the rod removes the bearing from its case.

  • Patent number: 4669170
    Abstract: This invention is an improved concept of the clamp shown in U.S. Pat. No. 3,736,629, as issued June 5, 1973. This construction of a clampingdevice includes forming two C-shaped arms, each of which is an assembly of two plate-like members of sheet metal. These two arm assemblies are pivotally retained at one end with the plate-like members in an overlay condition. A pivot pin has an enlarged center portion which acts as a spacer and has two eccentric cam areas sized and spaced to actuate apertures formed in one of the arm pairs. Shouldered rivets retain these arm assemblies in spaced array and a stop pin secured in this pivot pin has a length sufficient to engage a secured rivet. At one limit of movement of the stop pin, the cam areas move one arm assembly to a maximum clamping force and, at the other limit of movement of the stop pin, the cam areas are in a reduced-force application.

  • Patent number: 4339113
    Abstract: A bar clamp of the type which uses standard pipe for the bar and modified for jacking. The jack includes first and second pipes of suitable length each threaded at at least one end thereof. The first pipe is substantially longer than the second pipe and has a first jaw member slidable therealong for quick positioning and lockable at any position. A mounting bracket having a threaded bore extending from one face thereof to and through an opposite face interconnects the first and second pipes. A second jaw member is slidable along the second pipe and movable by rotating a threaded rod that extends through an additional threaded bore in the bracket. A handle is swingably connected to one end of the threaded rod for use in rotating the same.

  • Patent number: 4235004
    Abstract: Disclosed is an improved puller especially adapted for removing pulleys from the shafts of engines such as lawn mower engines, small tractor engines, etc. The puller comprises generally a box-like member of heavy steel plates with one open wall. A jack screw is threadedly associated with one wall and a pulley, mounted on the shaft, is adapted to be received in position for operative thrust engagement with an opposite wall. Running in on the jack screw forces the hub or central portion of the pulley into operative thrust contact with the opposite wall, whereby the shaft is moved axially of the pulley, thus effectively removing the pulley without damage.

  • Patent number: 4128931
    Abstract: A clamping tool having a bracket arm with a stationary jaw at one end thereof. The bracket arm supports a movable jaw. Each of the jaws have slot openings with grasping means for use in applying tension clamps to cable members. The tool is modified to enable it to function as a cable fitting opening device through the provision of projections attachable to the jaws which projection can be urged towards one another by movement of the movable jaw to urge the projections into contact with projections or recesses of cable fittings to force the cable fittings to open.

  • Patent number: 4050139
    Abstract: A component for use in a piston pin remover and replacer device for assembling and disassembling the piston pin connection between a connecting rod and a piston head. The component is comprised of a base and an anvil member mounted on the base. The anvil member has a bifurcated portion which is composed of a pair of spaced apart legs which are spaced upwardly from the base. A rim is mounted on the inside part of the legs and extends coextensively therewith. The rim also extends in an arc between the legs at the bight portion of the bifurcated portion. A hollow sleeve member has an opening therein, the extended axis of which extends between the spaced apart legs and is equidistant from the rim throughout all parts of the arc. An arbor member is slidably mounted in the hollow sleeve member. A stop is provided inside the hollow sleeve member and a spring is provided for urging the arbor member to a position extending out of the hollow sleeve member and away from the stop.
