Description

atented Apr. 1l, 1944 g UNi'rin STATES PATENT orifice GOLF CLUB Fred B. Schaffer, Kansas City, Mo. y amputation July 24, 1942, seria1 No. 452,183

This invention relates to golf clubs, and more particularly to a head for the type of club heretofore known as a wood, the principal object of the invention being to provide a golf club in which the principal weight of the head is directly behind the ideal point of impact of the club with the ball.

Other objects of the invention are to integrate the striking face and weight member of a club head whereby the full effect of the intertia of the weight is imparted to the ball; to directly connect the weighting core of a club head and the club shaft; to provide a club head adapted to be molded of plastic material; to provide a club head adapted for use of transparent or translucent material in the construction thereof; to provide a club head having a weighting core in a plastic head; to provide a core for a plastic club head adapted to hold the plastic material in place; to provide for attaching a sole foot plate directly to the club head core; to provide a club head adapted to be molded around a cast core; to provide a club head which requires a minimum of finishing or machining; to provide a club head which is simple in construction, reliable, efficient and practically indestructible, strong, durable, and economical to manufacture in a proper shape and balance; and to provide improved elements and arrangements thereof in a golf club head of the character described.

In accomplishing these and other objects of the present invention I haveprovided improved' details of structure, the preferred form of which is illustrated in the accompanying drawing,

wherein:

Fig. 1 is a perspective view of a golf club head embodying the present invention, portions of the head being broken away to show the core.

Fig. 2 is a horizontal section through the club head showing an integral striking face, core and shaft connection.

Fig. 3 is a transverse sectional view through the club head on the line 3 3, Fig. 2.

Fig. 4 is a longitudinal sectional view through the club head on the line lli-ii, Fig. 2.

Fig. 5 is a perspective view of the integral striking face, core and shaft connection casting.

Referring more in detail to the drawing:

i designates a golf club embodying the features of the present invention, which preferably consists of a head 2, shank 3 and shaft d. The head is preferably molded or otherwise formed of p1as tic material such as pyralin, cellulose acetate,

cellulose nitrate, or other similar plastic compound which will give a translucent, transparent or variegated color effect and is preferably molded around a core 5 of brass or other suitable metal of such size and weight as to provide the proper weight in the club head and of such shape as to balance and increase the driving force of the club.

The core 5 preferably consists of a cylindrical member 6, cast integrally and centrally located on the rear face of a Striking plate 1, having a front striking face 8 adapted to be flush with the face* S of the plastic portion of the club head 2. The striking face preferably has curved side edges Il) beveled to .provide a wider rear dimension to effect a dovetailing between the plate and the cl-ub, as at Il, to assist in holding the plate in proper position on the club head. The cylindrical portion 6 extends rearwardly of the plate l a substantial distance through the club head and-is provided with grooves l2 diverging rearwardly and outwardly to form central conical portions I3 and shoulder portions i4 adapted to be engaged by the plastic material of the head 2 and to aid in holding the plastic material and core and prevent any dislodgment thereof. The rear portion of the core is preferably enlarged, as at l5, to form a suitable weighting mass at the rear of the mass of the club to increase the driving force and to properly balance the weight thereof.

Connected to and integral with the side ofthe cylindrical core is a rod connection member I6* which extends laterally as at I1 and upwardly as `at i8.. through the shank 3 of the club head for connection with the shaft ll as by a pin (not shown) extending through an opening i9 in 'the rod connection member IB, or by any other suitable connection or connecting means. The point of connection ad the end of the shank are preferably covered by a suitable ferrule 2U, as in conventional practice. The shaft 4 and the member I6 which is integral with the weighting core and striking plate cause the full force of the swing and inertia of the weight and club to be delivered directly behind the point of impact between the club striking face and the ball to increase the driving force delivered thereto.

It is preferable that the sole 2| of the club be provided with a sole or foot plate Z2 and that said plate be connected to 'the metal core 5 of the club to prevent any possible splitting of the plastic material and to maintain all of the metal weight of the club in one connected mass. Therefore the core is provided with downwardlyV projecting arms 23, carrying bosses 2li at thc lower ends thereof adapted to engage the upper surface of the plate 22 and be connected thereto by a screw 25 or the like. The sole plate is ush with the sole of the club head and said sole plate may be mounted on the core prior to the placing of the core in a mold and forming the plastic material of the head around the mold. The mold may' also be suitably formed to provide a recess for the sole plate whereby said sole plate may be attached to the club after molding. It-

is evident that the sole plate may be cast as a part of the core and striking plate if desired.

In assembling a golf club constructed as described, the striking plate, core and connecting member I6 are preferably molded and cast as one integral casting; that the shaft 4 may be connected to the rod member I6 by any suitable connection means; and that the plate 22 may be connected to the bosses 24 by the screws 25. The assembled core, shaft and sole plate are then placed in a-l suitable mold and a suitable plastic material, such as cellulose nitrate, or the like, is formed around the core in the shape of a conventional golf club wood, such as a driver, brassie, spoon, etc. The formation of the plastic portion of the head may be by injection or other suitable plastic molding process. It is also contemplated that the head may be formed of laminated wood, shaped to fit the core and impregnated with plastic material without departing from the spirit of the invention.

After the club head is removed froml the mold, the surface is in a finished condition and requires no Apolishing or the like. The joint between the shank 3 and the shaft 4 is covered with a ferrule to make a completed club.

It is apparent, therefore, that the present invention provides a golf club structure which is reliable, practically indestructible, and adaptable to quantity manufacture in which a proper shape and balance for the club may be economically attained.
