  • Patent number: 10293519
    Abstract: A mandrel bladder end fitting includes a compression housing defining a circumferential interior wall; the interior wall constitutes a first clamping surface. An expansion assembly, axially received within the interior wall, includes a plurality of wedges that collectively define a second clamping surface. The expansion assembly also includes a central core and a threaded member received within a threaded aperture of the central core. A radially extending flat washer, seated within the interior wall, prevents axial movement of the expansion wedges in one direction. Thus, upon rotation of the threaded member, the central core will move axially toward the washer, forcing the second clamping surface to move only radially outwardly toward the first clamping surface. As such, because the flat washer restricts axial movement of the expansion wedges, relative motion between first and second clamping surfaces; i.e., between the collective wedges and interior wall, is limited to radial movement, only.

  • Patent number: 10156261
    Abstract: Claimed is a splint joint for a drive shaft including a receptacle with an interior and with a drive shaft extending from the receptacle. A bushing having a bushing body is inserted into the receptacle interior and the receptacle and bushing are immovably affixed in resistance to rotation by friction. The bushing is affixed to a bushing ring with the combined bushing and bushing ring inserted into the receptacle. Machine bolts draw bushing and bushing ring together. The bushing and the bushing ring each have a single split and both have a spring function. As the bushing and bushing ring are drawn together the bushing ring is expanded into friction contact with the bushing receptacle interior and the bushing is compressed into friction contact with the bushing ring. Push bolts allow the bushing to be urged away from the bushing ring.

  • Patent number: 9879706
    Abstract: A high capacity radial-fit coupling bolt (or “expanding sleeve bolt”) has a pair of tapered sleeves about a shank of a bolt to which can be applied a tensioning load. An extrudable ring, or a compression ring, is interposed between a head nut or head flange at one end of the shank, and one end of an inner sleeve. A tensioning load is applied to the shank, the inner sleeve causing the outer sleeve to expand diametrically. At a preset load limit, the extrudable ring is extruded through at least one bore in a drive piston between the head nut and the extrudable ring, to allow shank to move relative to the inner sleeve until the tensioning load is fully applied. Alternatively, a drive member is provided between the head nut or head flange and the compression ring, and at a preset limit, the compression ring allows the shank to move relative to inner sleeve until the tensioning load is fully applied. The preset limit will typically correspond to the force required to fully expand the outer sleeve.

    Abstract: A lock that includes a wedge that is used to releasably secure separable components of an assembly together. The wedge can be used with a spool. The wedge and spool are threadedly coupled together to drive the wedge into and out of an opening in the assembly without hammering or prying. The direct coupling of the wedge and spool eliminates the need for bolts, washers, nuts and other hardware so as to minimize the number of parts. As a result, the lock is inexpensive to make, easy to use, and unlikely to become inoperative because of lost or broken parts or due to fines or other difficulties encountered in harsh digging environments. Further, the wedge can be driven into the assembly to provide the degree of tightness necessary for the intended operation and/or to re-tighten the assembly after incurring wear during use. A latch assembly is preferably provided to securely hold the wedge in place and avoid an undesired loss of parts during use.

The diameter of the second portion is slightly larger than an inner diameter of the sleeve. The third portion has a diameter slightly larger than the second portion. When the bolt is inserted into the sleeve, the sleeve expands resulting in an increase of its outer dimensions against the surface of the driving shaft blocking it axially in position as it is pressed against the yoke. The third portion of the bolt is received in one of the holes, thereby seating the bolt with respect to the yoke.

  • Publication number: 20080274822
    Abstract: An apparatus for selectively adding weight to the hollow shaft of a hand-held implement. One embodiment includes an upper cylindrical member, a lower member, and an expansion ring that fits between the upper and lower members. These components are sized slightly smaller than the inside diameter of a hollow shaft, such as a golf club shaft. Each component includes an axial bore, through which a screw with an elongated barrel extends. The axial bore of the upper member is enlarged at its upper terminus to receive the cap of the screw, and the axial bore of the lower member is threaded to receive the screw. This assembly is inserted into a hollow shaft, and as the screw is tightened, the lower member is drawn into the upper member, compressing the expander ring axially causing it to expand radially until a friction fit with the inside surface of the hollow shaft is achieved.

  • Publication number: 20080274823
    Abstract: An apparatus for selectively adding weight to the hollow shaft of a hand-held implement. One embodiment includes a deformable upper cylindrical member, a lower member, and a rod coupled between the upper and lower members. These components are sized to fit within a hollow shaft, such as a golf club shaft. The upper deformable cylinder includes a chamber at its upper end, into which an oversized insert is inserted. This causes the deformable cylinder to expand radially creating a friction fit with the inside surface of the hollow shaft. The lower member may include an annular deformable member, such as an o-ring or a sleeve, stretched over its outside surface to create a snug fit within the shaft.

  • Patent number: 7437857
    Abstract: A compression anchor for holding a support member, such as a cylindrical handrail, is disclosed. The anchor includes a body having a cavity and a wedge portion that connects to the body using thick threads, such as 2-4 ACME 2-G threads. The wedge is substantially cylindrical and encircles a support member received in the cavity. A compression ring is in contact with the body and the wedge portion. As the wedge portion turns relative to the body using the threads, the compression ring expands and contracts to loosen or tighten the connection between the received support member and the anchor. The wedge portion and the body are corrosion resistant.

  • Patent number: 7174661
    Abstract: A lock that includes a wedge that is used to releasably secure separable components of an assembly together. The wedge can be used with a spool. The wedge and spool are threadedly coupled together to drive the wedge into and out of an opening in the assembly without hammering or prying. The direct coupling of the wedge and spool eliminates the need for bolts, washers, nuts and other hardware so as to minimize the number of parts. As a result, the lock is inexpensive to make, easy to use, and unlikely to become inoperative because of lost or broken parts or due to fines or other difficulties encountered in harsh digging environments. Further, the wedge can be driven into the assembly to provide the degree of tightness necessary for the intended operation and/or to re-tighten the assembly after incurring wear during use. A latch assembly is preferably provided to securely hold the wedge in place and avoid an undesired loss of parts during use.
