Projections II and 14 embedded in the plastic provide exterior engagement between the plastic and the sleeve while extension of the plastic into t0 apertures 13 and I la, and the interlock of the plastic extending through apertures 14a provide an interior engagement constituting a firm anchorage for the sleeve in the head, which resists withdrawal of the sleeve from the hosel, and 5 especially resists torque applied when the golf club is used to strike a ball tending to rotate the sleeve in the head. apertures I la equalizes resistance to torque acting between the sleeve 10 and the head 18 in opposite directions.To avoid substantial camming action tending to force the plastic away from the sleeve, fins II and 14 extend substantially in radial direction from the sleeve with Stheir surface portions disposed longitudinally thereof. 14, 1945 FOREIGN PATENTS Country Date Great Britain ----- Sept.The plastic material used to form the head 18 surrounds and embeds the outwardly lanced fins II and 14, and extends into the apertures I Ia at the base of the fins, as well as apertures 13 in the upper portion of the sleeve, while at the lower end of the sleeve, the plastic material flows into the interior of the sleeve, extending through apertures 14a at the base of fins 14 forming an interlock therewith.

This invention relates to improvements in golf clubs, particularly in' means for receiving and fastening the shaft of a golf club in a molded plastic head therefor.

It is an object of this invention to provide a metal connector in the form of a sleeve adapted to be secured to a shaft, of simple,...

Adjacent the base of the tube a plurality, for example, a pair of projections or fins 14, preferably of somewhat greater size than fins 11, are lanced outwardly on opposite sides of the sleeve 10 intermediate the ends of the tube.

An internally threaded portion 15 can be provided intermediate the ends of the sleeve for engaging the threaded end 16 of a shaft 17, to which the sleeve is to be secured.

sides of the -aperturesý at their base, that rthey;-offer similar resistance totorquelin either direction..':. The lanced out fins are distributed at spaced points longitudinally and circumferentially of the 1 sleeve.

An advaritage of ýthe preferred' constructionh in accordance withl-my:invention wherein aper-' tures are formed- diametrically opposite'- the lanced"6out'"projectionris'lies 'in the fact that the latter can be conveniently 'formed by lancing out portions of the surface with a tool or instrument- 'inserted bthrough'the oppositely disposed-apertures.' 5 Other objects and advantages of the invention will appear from the following description taken in connection with the accompanying- drawing wherein: Figure 1 is a perspective view -of a ferrule or 0 sleeve accordance with my invention; Fig. For example, the lanced out fins can be formed at approximately 90° intervals around the sleeve, and arranged along a spiral or helix extending lengthwise thereof. 2, the projections II are preferably lanced out on alternate sides of the resulting apertures.

Thereafter, if required, the lower end of the sleeve can be machined off so as to be flush with the lower surface of the head 18.

After removal of the core, the shaft IT is inserted into the hosel and secured therein by engagement of threads 16 with corresponding internal threads 15 of the sleeve 10.

However, other means can be used to secure the shaft in engagement with the sleeve. 4, a sleeve 10a is provided which is similar to sleeve 10 except that the threads 15 on the sleeve are omitted.
