Application filed Ootoler 4,1894. Serial No. 524,893. (No model.) is preferably spring-steel, drop-forged or otherwise made of the desirable shape. - .,

The walls B and C are sufficiently thin to' 55 be resilient and to give elastically when the ball is struck. Although both walls are shown of the same thickness, a certain measure of utility might be obtained if the front wall only were sufficiently thin to be resilient. The 60 rear waK C may be curved inwardly, as shown in Fig. 5, in which ease a portion of the transverse pressure on the filling E would be converted into a longitudinal strain on the filling in the larger ends of the space. 65

In all the forms shown by suitably proportioning the steel walls the elastic .filling or metal spring might be dispensed, with·.

Although I show my invention applied to only two forms of club, it will of course be 70 understood that it is equally as applicable to all the various forms of golf-clubs in use, whether of wood or metal.

Although I mention vulcanized rubber as the preferable material for the filling, it be- 75 ing unaffected by ordinary extremes of heat or cold, many other substances—such as vulcanized gutta-pereha, spdhge rubber, cork, wood, or, in fact, any elastic or semielastic substance—might be used for the same pur- 80 pose. , ,

By constructing a golf - club as above described I am able, with a club of equal or less weight than those ordinarily in use, to obtain greater driving power with the same or less 85 exertion on the part of the player.

I am aware that i# is old'to provide a golfclub with one resilient side, as shown in the English Patent No.-3,822 of 1893, and to insert a cushion of elastic material in a frame 90 Or hacking of metal, as illustrated in the English Patent No. 5,741 of 1891, and hence make no claim-to sucli constructions. I regard my invention as essentially different from either of those above mentioned, inasmuch as a club 95 formed with thin resilient walls on all sides having a space between their lower edges makes a very differently - acting i club from one in which a resilient side is secured to a hard backing such as has been heretofore ico used, even if the wooden backing is made hollow. When the four walls are made resilient and the blow is delivered from one of said walls, a great part of the strain from the

To all whomCii may concern:

Be it known that'L Willi am Tyndale Jennings, civil engineer, of the city of Toronto, in the county of York and Province of Onta5 rio, Canada, have invented a certain new and Improved Golf-Club, of which the following is a specification.

The object of my invention is to devise a golf-club superior in driving power to those t o ordinarily in use; and it consists, essentially, of a club the head of which is constructed preferably of spring-steel, the metal being so shaped as to leave resilient steel walls surrounding a central space, which preferably 15 has a metal spring or a filling of elastic material arra .ged therein, the whole being constructed in detail substantially as hereinafter more particularly-described.

Figure 1 is a perspective view of a head of 20 that form of golf-club known as a “.cleek.”

Fig. 2 is a verticil, longitudinal section of a driver. Fig- 3 is a cross-section of the same through line a b. Fig. 4 is a plan view of the same? Fig. 5 is a plan view of an alternative 25 form of the same. - Fig. 6 is. a plan view of the same, showing a metal spring arranged in the center space. ^;

In the drawings like letters of reference indicate corresponding parts in the various fig30 ures. '., .

A is the head, of a golf-club, composed of walls B and C, connected at the ends and inclosing a space D. ..

E is a filling, preferably of vulcanized rub35 ber, gutta-percha, or any suitable elastic material.,,

In the cleek illustrated in Fig. 1 the space D is wedge-shaped, as shown. In the forms illustrated in Figs. 2 to 6 the space is open 40 both at the top and bottom. - .

In order to prevent the filling from falling out, it is desirable that the metal forming the ends of the space W be bulged, as shown at a a, or that it be Mherwise suitably shaped 45 to accomplish the.purpose. (See Fig. 2.)

In the form shown in Fig. 6 a metal spring E' is substituted for the elastic filling E. This bears at its center against the front wall B and at its ends against the rear wall C. In50 stead of the flat spring a coil-spring bearing against the centers of the front and rear walls might be used. The metal used for the head

B 50,Θ76 blow is felt by the rear and short end walls. In fact, the. rear wall may be said to greatly help the front wall in giving the “ rebound?’ This is evident from the fact that when the 5 blow is delivered the center of the resilient face with which the blow.'is given is forced slightly inward, thus shortening the distance on the front between the end walls, and as this shortening of the space between the end r o walls at the front will have to be compensated the rear resilient wall gives sufficiently - to accomplish this effect. Of course, as the front and rear walls are of resilient material, this occurs instantaneously and each resili15 ent Avail as quickly tends to resume its initial position, and it Avill thus be seen that the resiliency of the rear· Avail is used as well as that of the front Avail and that the rebound is therefore made partly by each resilient 20 wall.
