  • Patent number: 6238302
    Abstract: A golf club head with a polymer insert is disclosed herein. The polymer insert is disposed in a recess of the club head in which the recess has a depth that is greater than the thickness of the insert. The polymer insert has a plurality of tabs on its perimeter to engage the recess walls to allow the insert to essentially float within the recess. An adhesive is disposed between the rear wall of the recess and an interior surface of the insert. Further, an adhesive is applied between the plurality of tabs, and preferably over the exterior surface of each of the plurality of tabs. The plurality of tabs allow for a uniform surface on the face of the club head TO without having the insert occupy the entire recess. The insert may occupy between 55% to 75% of the face of the club head. Further, the insert may occupy between 10% to 25% of the volume of the club head. Yet further, the insert may be 1% to 5% of the weight of the club head. The insert may be composed of a thermoset material.

  • Patent number: 4573823
    Abstract: An adjustable pass-through joint comprising a main joint body having a first bore longitudinally therethrough, a second bore orthogonally intersecting said first bore, a third bore intersecting said second bore and a fourth bore intersecting said second bore, a cylindrical locking member rotatably mounted within said second bore and having a partially-threaded opening in line with said first bore, a threaded rod slideably installed within said joint body, and a shaft insertable within said third bore which, by wedging itself between one side of said third bore and a cut-away surface on said locking member, retains said cylindrical member in an angular position where the threads of said partially-threaded opening are locked with the threads of said rod, preventing longitudinal movement of said rod within said joint body.

  • Patent number: 4508466
    Abstract: A lockable telescopic joint is provided wherein two telescopic members may be fixed against telescoping action by tightening a glade nut, and yet after tightening there remains a substantial degree of rotational freedom so that one telescoping member may be rotated relative to the other by hand, and yet the members will not telescopically collapse short of applying considerably more compressive force than need be exerted to rotate the members.
