IMPACT INDICATOR FOR GOLF CLUBS Filed July 15, 1935 INVENTOR BY Q 2 ATTORNEY Patented Mar. 15, 1938 UNITED STATE PATENT OFFIQE IMPACT INDICATOR FOR. GOLF CLUBS Michael J. Plese, Brooklyn, N. Y.

Application July 15, 1935, Serial No. 31,396

3 Claims.

My invention relates to improvements in golf clubs or sticks and more particularly has reference to and is illustrated in the accompanying drawing in its application to a golf club provided with means in the head thereof for measuring the impact or blow to determine the distance a ball will travel when struck; the same being especially useful in practice indoors where the ball can be driven against a net, padding or otherwise.

Referring to said drawing, I have illustrated in Fig. 1 in perspective, parts being broken away, a suitable application of my invention. Fig. 2 is a longitudinal sectional view of the same on line 2-2 of Figure 1, Fig. 3 is an enlarged longitudinal section of the indicator and its mounting. Fig. 4 is a plan view, looking down upon the top of the head of the club. Fig. 5 is a view looking in at thebutton or disk which receives the impact of the ball. Fig. 6 is a perspective view of the same, and Fig. 8 is a view of the outer cylinder or casing within which the parts shown in Figs. 5 and 6 slide.

8 indicates the hammer or head of the golf club, and 9 the shank where the handle is attached. The club is cut away at the top as indicated at Hi, to allow for the movement of the pointer or indicator ll, and I2 is a slide or cover which may be open or provided with a transparency at I3 to reveal the scale shown below.

A hole is bored in the head 8 as indicated at I4 to receive the plug 15, which in turn may be secured by the screw IS, the plug having a reduced threaded portion ll, to receive the threaded outer shell l8 within which is slideably mounted the button or piston 19, resiliently projected by the compression spring 20 against the annular flange or stop 2!.

The button or piston portion 19 is provided with a bracket 22, which moves therewith in slot [8' to operate the rear end 23 of the pointer ll, preferably mounted at 25 as shown to advantage in Figs. 3 and 7. It will be seen that the threaded shank 25 is screwed into the head of the club, after which the pointer H is dropped over the upward extending pin 21, around which is secured the compression spring 28, which when the housing 29 is pressed down, is adapted to receive the nut 30, thus pivotally holding the pointer ll freely to turn thereon.

In swinging the club, the ball may be struck by the button l9 and the spring 20 is compressed, the inward travel of the piston I9 carrying the bracket 22 which strikes the right end 23 of the pointer ll, thereby indicating upon the scale l3 the force of the blow or impact.

The nut 30, shown to advantage in Fig. 3, is 5 turned down sulficiently so that there is enough friction upon the pointer ii to hold it in the position to which it is moved by the impact, so as to indicate the reading upon the scale I3 before the nut is released for the next drive. 0

Of course, it will be understood that modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention, as claimed.

I claim: 15

1. In combination with a golf club, a spring projected piston therein, said piston having means projecting laterally thereof, a pivoted pointer and a scale visible from the outside of said club, said pointer movable in the path of movement of part of said means whereby when a ball is struck by said piston said pointer is moved by the latter and indicates the striking force of the blow.

2. In combination with a golf club, a spring projected piston in the head of the club, a pivoted pointer and a scale visible from the outside of the club, lever means connecting said piston with said pivoted pointer to engage the same, said pointer being pivoted so as to engage said 30 lever means in" the path of movement thereof and means for adjusting the position of said pointer on said scale, said lever means being disposed so as to permit the pointer to remain in indicating position until reset by said adjusting 35 means.

3. In combination with a golf club, a spring projected piston therein, lever means projecting laterally from said piston, a pivoted pointer and a scale visible from the outside of the club, said 40 pointer being pivoted so as to engage said lever means in the path of movement thereof, and. means for manually adjusting the position of said pointer on said scale, whereby when a ball is struck by said piston, said pointer is moved by said lever means to indicate the striking force of the blow, the pointer remaining in said indicated position until manually reset to the initial position.
