US3876176A - Apparatus for molding golf shoe bottom with detachable spikes - Google Patents

Abstract

A golf shoe bottom mold is provided with a plurality of bores corresponding in number and position with the spikes to be removably mounted on the golf shoe bottom. A plug of a compressible material, such as a fluorocarbon polymer, is mounted in each bore and is provided with a central bore to receive the spike end. Each spike has an enlarged flange whose diameter is substantially that of the plug. The spikes are removably mounted in spike receptacles loosely carried by an anchor plate and are pressed against the bottom mold so that the flanges compress the plugs forming a tight seal. A highly plasticized elastomer is injected into the mold between it and a shoe upper to form the shoe bottom with the spikes removably in place on the shoe bottom.

Claims (1)

1. Apparatus for use in molding a golf shoe bottom comprising a. a golf shoe upper having a bottom portion; b. a plurality of spike receptacles secured to said bottom portion, each of said spike receptacles being provided with an internally threaded socket; c. a plurality of spikes each having an externally threaded portion removably threaded into the internally threaded socket of use of said spike receptacles, a spike portion projecting from said externally threaded portion and a circular disk flange surrounding said spike portion, the diameter of said flange being substantially greater than the diameter of said spike portion; d. a bottom mold adapted to receive said bottom portion, receptacles and spikes; e. said bottom mold being made of a hard material provided with a plurality of bores; f. a cylindrical plug of a material of greater compressibility than that of said hard material fitted into each of said bores, each of said plugs having a central recess into which one of said spike portions is received and also having an upper surface surrounding said recess, the outer diameter of said upper surface being substantially equal to the diameter of the flange surrounding said spike portion, the lower surface of said flange being in firm engagement with the upper surface of said plug substantially throughout its diameter; g. said bottom mold also being provided with a portion to support the bottom portion of said upper spaced from said flanges during molding; and h. an anchor plate rigidly connected to said bottom portion, said spike receptacles being loosely mounted on said anchor plate with a substantial degree of freedom of motion transverse to the plane of said anchor plate.
