Application filed June 8,
This invention relates to game-clubs and has for its object to provide improved means for retaining striking inserts in place and at the same time to shape them so as to make certain of driving the ball in the intended direction.
Various types of inserts have been suggested for the striking face of game clubs,
such as a golf driver or brassie, polo mallet, etc. The impact of theball upon the elastic i insert causes considerable momentary dis tortion and flexure, which, While not appreciable 'to the eye, nevertheless tends to loosen the insert. l/Vhen the ball hits the edge of the insertV the distortion thereof maynot l e uniform and may impart a.V wrong direction to the ball. rlhe elastic insert in a golf club, for, example, cannot be put in place from the rear of the strikingface because of the presence of the counterweight in this part of the club head and in order that the impact from the insert shall not be transmitted to the connteriveight and loosen the same, it is desirable to have a substantial thickness of Wood or other material between` the insert and the Weight. When, therefore,` the inserts must be positioned fromV the striking face it will be seen that the problem of retaining` them securely in position is more diiiicultthan if they could be inserted from the rear.
According to this invention some of these disadvantages are overcome not only by lmaking the Width of the insert greater, but more especially by reinforcing the sides and giving them an outward taper 'from an enlarged base toward the striking face whereby the force of impact with the ball is taken up by the enlarged body of material making up the insert, resulting in less distortion and loosening. The foundation is enlarged re-A sulting in the stresses Within the insert, which are not taken up by the body being distributed over a largecontact area with the Wood or other material of the club head. The insert of this invention is made in several parts With the axis of at least oneJ part angularly disposed to that of another in order to exert a Wedging action and prevent the several parts Working loose.
Specifically a. central insert of cylindrical or other substantially uniform cross sectionl is located in cut away portions of lateral inserts which are preferably longer than the central insert to partially provide founda- 1923. senat No, 644,072.
tion therefor. and which are angularly arranged to diverge from the striking face TO YARDSIORE GOLF CLUB Y whereby a nf'edging action is obtained and the severalparts of the insert function as a large singleinsert to take up the lstresses Within the material.

Fig. 6 is a section on the line (3M-6a of Fig. 4, and i 5 Fig. 7 is a section on the line 75L-a of Fig. 5. i
F or the sake of illustration this invention has been shown embodied in a Wooden golf club'such 'as a driver 10 having a striking face ll containing' an insert l2 of elastic material such as galalith, or ivory, for eX- ample. The bottom 'of the club is provided with thecustomaryfmetal platey 13While the rear face contains the 'usual counterweight 14 for obtaining the proper balance.
The insert shown invliigs. l to 3 comprises a central insert l5 havingon each side thereof lateral insertsrl and 1'7" which are longer than the central insert, arranged a section on the line 5?5av of with their axes diverging from the striking face and groo-ved to cooperate with the central insert in the manner shown. lateral inserts. not only provide additional Width forI the striking face but by reason of their angular disposition provide an increase in the body `of the insert which is effective to take up impact strains Within the insert and transmit less of these strains to the .material of the club head. The enlarged base for Athe insert is effective to more uniformly distribute the remaining Fig. 3 is a horizontal section on the line a section on the line 2&-25 of These i lim stressesv imparted to the club Vhead over-a n larger area. The end Walls 18 of the grooves in the lateral inserts pro-vide afoundation for the central insert inasmuch as the lateral inserts are of 'greater length. To help retain each insert in position they are provided vvith cavities 19 near the base adapted llU niay be preiorined hetero to contain ceinen'titious material, or glue. is a means 'lor making astronger conne@ tion, a channel 20 in `each insert may con- `tain a strip of the ceinentitious material Van inner insert 21 or the saine i' inaterial,`
which may re of a diiierent color to provide an attractive appearance, and in the saine inannerthe lateral inserts 1G and 17 may be the saine er of diiierent colors, it desired.
ln the enibodinient illustrated in Figs. l to Tthe central insert grooved to receive a plurality oit sinaller lateral inserts Q2, 23, 24% and which are also angnlarly disposed with their ares diverging Aifroin the striking tace. Here again each insert may be sinnlarly provided vvitli ceinentitions cavities 19 and grooves 20 in order to n'iore lirinly retain them in position. 'lhe central insert is inserted in position and the ranged holes are then drilled tor the lateral inserts 22 io. lt will be seen that in this enihodirnent also the several inserts cooperate to `provide the ivedging action for securely being` retained in position.
Amongtlre advantages ot this invention niay be mentioned the substantially dovetail cross section to the insertas shown in Fig. 3, whereby the increasing Width to the material behind the striking face is etiective to take up the shocks of iinpaet Within y angularly ar-Y the material and transmit less stress to the material ot the club head with the result that less distortion and loosening of the insert is present' than occurs with those inserts having substantially parallel sides. Another feature is the Wedging action exerted by one insert upon another `Wherelijy both are retained in position. The use of cementitious niaterial in the grooves near therba-se of the inserts helps to lirinly po `ition the insert. The enlarged base is edective in transmitting the impact stresses over a larger area. The provision of the central insert 15 with a foundation in each oi the. lateral elastic inserts in an.
other feature helping to have the iinpact shocks taken up Within the body of elastic material and less imparted to the material ofthe club head. A p i I fclaiin: n
