HEAD FOR POLO-CLUBS.

Patented May 14, 1912.

To all whom it may concern:

Be it known that I, ROBERT D. HAYES, a citizen of the United States, residing at New Haven, New Haven county, State of Connecticut, have invented certain new and useful Improvements in Heads for P010- Clubs, of which the following is a full, clear, and exact description.

My invention relates to polo clubs, particularly clubs for playing the game of pony polo, and in which the side of the Ilgeald of the club is employed for driving a The object of the invention is to improve the construction of the oluband provide a,

head of maximum strength, and yet so constructed as to secure greater driving force with a given blow than can be secured by the ordinary polo club head as now constructed.

In the accompanying drawings, Figure 1 is a side elevation on a small scale of a polo club complete. Fig. 2 is a relatively enlarged plan view of the head with the shaft detached. Fig. 3 is a still further enlarged cross sectional view on the line 33 of Fig. 2.

1 represents the shaft or handle of a polo club at the lower end of which is a head. The head is constructed of not less than three layers of laminations of wood, as indicated at 2, 3 and 4. The layers 2-4c form the striking faces of the club head, by which I mean, the faces which contact with the ball. The lamination 3 constitutes the core. Whereas the layers 2-4 aremade of a highly resistant material, preferably wood, the core 3 is made of a relatively springy material, preferably wood, which I find tends to augment the driving power of the club head. The several layers which constitute the head may be secured together inany suitable way, as by glue or cement. The outer laminations 24 should preferably be made of a wood having a hard, dense grain, while the grain of the core should be relatively porous and springy.

5 represents an opening or hole which is designed to receive the end of the shaft or stick 1. As shown, this hole is preferably oblong or oval in-cross section, the major axis thereof being in alinement with the core 3. The end of the shaft 1, when fitted into this oblong hole and held therein as by glue is very securely retained, and is guaranteed against rotation in the head, the strain which tends to rotate being resisted by the cross sectional shape of the opening, rather than by the glue or cement, which latter, therefore, merely performs the function of preventing the shaft from being pulled out.

It will be observed that the hole 5 extends obliquely relatively to the axis of the head, and that it is preferably formed wholly in the central lamination or core 3. Since polo club heads should be of a sub .stantially standard size and weight, I find that said size and weight may be maintained, even though the outer lamination or striking faces are made of heavier and more resistant material than the core, since, by selecting and using a material of sufficiently less weight for the core, compensation or due allowance for the excess weight of the outer laminations may be made.

What I claim is:

1. In a polo club, a head comprising not less than three laminations secured together lengthwise of said head, the interior lamination or laminations being formed of relatively springy material as compared with the external lamination or laminations and having a handle shaft secured thereto and extending therefrom.

2. In a polo club, a head comprising not less thanthree laminations secured together lengthwise of said head, the interior lamination or laminations being-formed of relatively springy material as compared with the external lamination or laminations, and being centrally apertured to receive a handle shaft, the material of the exterior lamination or laminations being also more dense and heavier than the material of the interior lamination or laminations.

3. In a polo club having a head composed of not less than three laminations, the external lamination or laminations being of heavier material than the interior lamination or laminations, said head having a passage obliquely arranged and centrally located between the ends thereof and entering the exposed edge of the internal lamination or laminations.

4. In a polo club having a head composed of not less than three laminations, the external lamination or laminations being of heavier material than the interior lamination or laminations, said head having a passage obliquely arranged and centrally .10-

cated between the ends thereof and entering the exposed edge of the internal lamination or laminations, the cross sectional outline of said opening being elongated in the line of the club head.

5. In a polo club having a head composed of not less than three laminations, the external. lamination or laminations being of heavier material than the interior lamination or laminations, said head having a passage obliquely arranged and centrally located between the ends thereof and entering the exposed edge of the internal lamination or laminations, the cross sectional outline of said opening being elongated in the line of the club head, and a shaft fitted to said opening and secured therein.

6. In a polo club, a laminated head including not less than three laminations arranged longitudinally thereof, said head tapering from the center toward the ends, an oblique shaft passage extending through said head obliquely and between the outside laminations, the material of the interior lamination or laminations being less dense than the material of the side faces or external lamination or laminations of said head.

7. In a polo club, a laminated head including not less than three laminations arranged longitudinally thereof, said head tapering from the center toward the ends, an oblique shaft passage extending through said head obliquely and between the outside laminations, the material of the interior lamination or 'laminations being less dense than the material of the side faces or external lamination or laminations, the cross sectional shape of said shaft passage being elongated substantially in the line of the axis of the head.
