It is an object of this invention to construct a golf shaft which at most costs but slightly more than the ordinary steel shafting and which has the lasting qualities of steel and the good playing qualities of woodin other words a steel shaft with a wood feel.
A still further object of this" invention is to construct a shaft for a golf club which is characterized by a hollow tubular metal steel" shaft of usual designwith a core or sponge rubber.
As a still further object of this invention it is proposed to use the hollow shaft as the moldfor the sponge rubber core. The core thereby is cemented or held firmly in place without further handling after molding. This method is recommended,although the core can be molded separately and later inserted and cemented in the hollow shaft.
A still further object of this invention is to construct the shaft with a double wall and to fill the rubber sponge core in between the double wall or inside within the inner wall, or at both places.
The invention furthermore proposes the provision of means for changing the resiliency and shock absorbing qualities ofthe rubber core.
A still further object of the invention is the construction of a shaft for golf clubs and the like which is of simple durable construction, dependable in use and efficient in action, and which can be manufactured and sold ata reasonable cost.
For further comprehension of the invention;
and of the objects and advantages thereof, refer,-
ence will be had to the following description and accompanying drawings, and .to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings forming a material part of this disclosure:- I

Fig. '7 is still another view similar to Fig. 3, but showing another modified form.
Fig 8 is a fragmentary view similar to Fig. 2, but illustrating another embodiment of the invention.
Fig. 9 is a section of Fig. 8. i
Fig. 10 is a view similar to Fig. 9, but showing the strip within the rubber core turned at a 90 angle so as to change the resiliency of the core.
A golf club constructed according to this invention comprises a hollow metal shaft 10 or tubing covered at the top with a grip 11 ora leather wrapping. At thebottom an iron head -12 is shown attached upon themetal shaft or tubing by a rivet 13. When thus arranged the metaliron head is in intimatecontact with the metal shaft or tubing. Vibrations which tend to be set up in the shaft when a golf ball is struck will be directly communicated from the iron head to. the shaft in that they are in intimatecontact. A rubber 14 is disposed within the view taken on the line '9- -9 V absorb the vibrations.
If one so desires, the iron head may be insulated from the shaft by suitable vibration absorbing material engaged around the bottom end of the shaft and disposed between the parts. A- cap or a plug 15 is engaged within .the free-end of the tubing so as'to close it. In Fig. 3 the sponge rubber core is very clearly shown within I the wall of the tubing. X
This invention eliminates the objectionable 'shock or vibration transmitting character of ordinary steePgolf shafts. The golf club shaft according to this invention ha's'the desirable qualities of steel, being fundamentally of similar construction, and hasin addition the sweet feel of wood shafting. The new golf club shaft eliminates objectionable shock or vibration and in addition does the following: 1
l. Strengthens the shaft against breaking.
2. Makes the whipping point further down on the shaft than the ordinary steel shaft-which is considered a desirable playing quality.
3. Gives the entire club a better or improved dynamic balance or swinging weight. This dynamic balance is effected by improved torsional qualities, specific gravity, etc., due to its inherent H nature. 105
The hollow shaft can be used as amold for the sponge rubber core, the core thereby being cemented or held firmlyin place without further While this method of the core may be made separately and later inordinary comfort and satisfaction due to freesorted in the hollow shaft. The sponge rubber dom from all shock or vibration, therefore mak-s core acts as a vibration dampener and eliminates ing for more efficient play or performance. the objectionable shock of vibration when the While I have shown and described the pre- 5 ball is struck in play.
