' INVENTOR/ $4 A TTORNEYQ FIG. I I

Patented Apr. 19, 1932 UNITED STATES JAMES B. HUNT, F DAYTON, OHIO GOLF CLUB HEAD Application filed. March 8,

This invention relates to new and useful improvements in golf club heads.

It is the principal object of my invention to construct a golf club head of spring metal that is so formed or cut away as to obtain the greatest resiliency. This is accomplished by using a very high grade of carbon steel in the alloys which will impart to the club head the highest degree of resiliency and toughto ness. The chrome vanadium steels are particularly adapted to meet these requirements if they are properly treated after the club is ma e.

The advantages'of my invention may be achieved by fashioning the spring metal club head in a number of ways, one of which is by working a depression in it back of where the ball impacts, and another by grooving or perforating the head to leave a thin sheet of 2ft metal to receive the ball.

All of these types of head can be mounted on woodor steel shafts at the pleasure of the maker.

In the accompanying drawings illustrating my invention, Figure 1 is a rear elevational view of a spring metal golf club head formed with a depression back of the ball-impacting surface. Figure 2 is a cross sectional view taken on the line 22 of Figure 1. Figure 3 is a rear View of a spring metal club head formed with longitudinalgrooves back of its ball impacting surface. Figure 4 is a rear view of a club headformed with cross grooves instead of the longitudinal ones shown in Figure 3. Figure 5 is a front View of a golf club head formed with a slot back of the place where the ball impacts. Figure 6 is a bottom view of said slotted head. Figure 7 is a bottom view of a golf club head formed with a plurality of slots behind the ball impacting surface. Figure 8 is a side view of a golf club head formed with a series of vertical holes behind its striking face. Figure 9 is a bottom view thereof. Figure 10 is a side view of a golf club head showing said holes running longitudinally behind its striking face. And Figure 11 is a bottom view of a club head in which said holes are disposed vertically.

Referring to the accompanying drawings 1927. Serial No. 173,648.

for a detailed description of my invention, the numeral 1 in Figures 1 and 2 designates a golf club head constructed of spring metal that is formed with a depression 2 back of its striking face 3. This depression is prefiency, may be likened to a tennis racket stringing, with the surrounding metal forming the solid frame. The thinness of the strip 3 is so adjusted as to bring out and impart to the ball the full resiliency of the metal of which the head is made. Such metal is preferably a chrome vanadium steel. 7

In Figure 3 I have shown a golf club head 4 of spring metal that is formed with a fan like series of longitudinal grooves 5 which occupy the space of the depression 2 in Figure 1. The metal striking face of the head in front of these grooves is made thin, and therefore extremely resilient, by them.

In each instance, the resilient quality of the metal of which the head is made, is increased by removing the metal, either partially or wholly, behind the face of the head which receives the impact of the ball.

A similar result is achieved by providing a series of vertical grooves 6 behind the striking face of the golf club head 4, as in Figure 4:.

Such a result may also be obtained by forming a semi-circular slot 7 behind the striking strip 8 of the club head 9 in Figures 5 and 6, or by providing a series of such slots 7 behind said strip as in Figure 7. In each instance a thin strip of spring metal 8' is formed to resiliently receive the impact of the ball.

In Figures 8 and 9 vertical holes 10 of dif- 9o ferent lengths are bored by a drill into a metal head 11 behind its striking face to bring out the resilient qualities of the metal, under the impact of the ball, by making said face thin as in the instancesbeforedescribed. 95

In Figure 10 holes 12 are. bored longitudinally by a drill into the spring metal club head 13 from its front end to leave a striking face of thin metal to resiliently receive the impact of the ball.

In Figure 11 the holes 14 are vertically bored into the spring metal club head 15 by a drill to accomplish the same results. In all of these instances, the boring of these holes in the club head achieves a two fold purpose; it allows the head to be constructed of a solid piece of high-grade steel, which hitherto has been impossible "because of weight, and brings out all theresilient qualities of the steel. 1

Having described my invention, I claim:

1. A golf club head constructed of spring metal and having a thin, integral impacting face, behind which holes open only at its rear side are formed in the head to increase the resiliency of said face.

2. A golf club head constructed of spring metal and having formed in its body portion a depression behind a thin integral face, said depression being open only at the rear side of said head.

In testimony whereof I have hereunto set my hand this 5th day of March, 1927.
