Abstract: A device for lubricating bearings and the like including a housing for containing a lubricant, and a movable piston adapted to be inserted into the housing in contact with said lubricant. The piston includes an upper concave surface, for communication of the lubricant with a bearing to be lubricated, and a passage for flow of lubricant. Compression of the piston against the lubricant causes flow of lubricant from below the piston to above the piston. An adapter, or volume-filling means, is disposed on the upper piston surface for filing a portion of a volume defined between the upper, concave piston surface and the wheel bearing. The volume-filling means includes lubricant flow passages for allowing lubricant to flow from said upper concave piston surface to the wheel bearing.

Abstract: A tool for reshaping or expanding metal tubular material includes an expandable mandrel having a plurality of duplicate spreader segments held in a cluster by an elastic O-ring about a wedge-shaped cam, each of the segments including an external, curved wall having a curvature corresponding to a curvature of an external curved wall in every other segment such that when all segments are equally spaced a predetermined amount, they form a cylinder having gaps between adjacent spreader segments for contact against an internal surface of the tubular material for reshaping or expanding said tubular material. The wedge-shaped cam includes a plurality of external faces corresponding to a number of internal spreader segment faces sloped to converge toward a front, mandrel-insertion or forward end of the cam and shaped complementary to the shape of the internal spreader segment faces for sliding engagement of the segments over an adjacent external face of the cam.

The compression member is operatively interconnected to an elongated post extending to an upper portion of the tool such that rotation of the post in opposite directions will cause the compression member to move toward and away from the gripping means to compress the coil spring or allow the coil spring to expand. The elongated post includes a plurality of flattened surfaces on an upper portion thereof adapted to receive a removable handle having an internal bore adapted to be securely and removably connected through a radially extending upper portion of the elongated post.

Abstract: A support device for supporting a longitudinal member, such as a threaded rod, in a desired position with respect to the support device includes a housing adapted to receive the threaded rod, transversely within a housing aperture, and a slide axle, slideably received axially within the housing. The slide axle receives the threaded rod and is slidable within the housing to (1) a first position frictionally engaging the rod and (2) a second position disengaged from the rod so that the rod can be relatively freely moved with respect to the slide axle. The rod supporting device includes a tightening member or lock nut to secure the slide axle in a locked position whereby the rod is tightly held against a housing bearing wall defining a portion of the housing aperture. The housing bearing wall is relatively smooth so that the threaded rod is tightly held in locked position by the lock nut, while minimizing axial movement of the rod with respect to the housing.

Abstract: Disclosed is a new and improved device for gripping and rotating a workpiece. The device includes an adjustable jaw, adjustable through a rack and pinion gear assembly so that torque applied to the gear member, for example by connecting the gear to a cooperatively fitting ratchet wrench drive handle, causes simultaneous jaw tightening and rotation of the device to achieve rotation of the workpiece without jaw slippage.
