GOLF-CLUB HEAD.

Application filed March 22, 1323. Serial No. 96,510.

This invention relates to improvements in golf club heads.

A golf club head of the peculiar type to which this invention has especial reference, is that which is illustrated in United States Letters Patent granted to me April 28, 1925, and which is numbered 1,535,270. This golf club is of one piece cast construction, the web or weight piece and the neck rising from the sole, the said web or weight piece being adapted to become practically an integral part of the shaft and in axial alignment therewith. Seated against the front side of said metal web is the face block, a recessed back block is retained at the rear side of said web. This golf club head as an entirety is of such balance, and the bore of the neck is in such axial alignment with reference to the shaft, that when the said head (in the action of swinging the club) is brought to contact with the ball, the driving force is transmitted with a hammer-like directness.

The impact force or shock is transmitted through the face block and to the web so that while there is a hammer like blow that imparts a true and dependable impulse to the ball, there is absence of tendency of the shaft to chuck, tremble or shiver.

The object of the present invention is to provide improvements-in construction whereby the hammer like efi'ect is improved, and at the same time the advantageous features of the truly balanced golf head are retained.

The -objects of my invention are accomplished byand the invention is embodied in the new construction, combination andarrangement of parts, shown in the accompanying drawings anddescribed in the fol lowing specification. The invention is defined in the appended claims.

In the drawings, the several parts "of the invention are identified by suitable reference characters applied thereto in the different views, in which-- a Figure 1 is a front view of my improved golf club head the lower being shown. I

portion of the shaft.

Figure 5 is a modification of my invention, the impact element b61119! made of one I am aware that impact elements, or so called inserts have heretofore been used in wooden golf club heads of various kinds, having for their purpose to provide rigidity at the point of impact. Veaknesses of such devices are that the tendency of the force.

carried by the head, is localized at the head of the insert, and whereby the result is frequently the splitting of the face of the head, or even of the head itself. To overcome this objection, impact plugs having screw threaded engagement} with the'club head have been devised upon the theory that while the plug is thus anchored agrainst'lonaitudinal movement under the force of the impact, the screw threads afi'ord increased thrust bearing surfaces. and serve to distribute the v1- bration through the club head, thereby obviating the tendency of breakage.

The present invention, as hereinbefore stated, has reference to a golf club head of that type in which the upright frame or body portion ofthe head is in axial alignment with the shaft. The great advantage of a golf club head of this type is, that the central portion being peculiarly weighted,

besides being. effective in imparting balance to the club head, is-effective as a hammer. Now to further increasethe efficiency of the golf club, my invention contemplates the combination with said vertical. body portion or web, of an insert, element which is made of material of suitable rigidity and specific gravity, and which said impact element projects throughthe face block, and whereby the driving' force of the golf club head at the moment of its striking, is applied to the ball directly by the impact element. By this combination and arrangement, the amount of impact shock which be received by the face block 1tself,'1s negligible, and

, and the bores of the face blocks.

strain.

tendency of the head or the shaft to tremble, or to be subject to even the slightest vibration, is practically eliminated.

My present invention is embodied in the metal golf club head of recent formation intended to accommodate a steel shaft 1 whose lower end portion is tapered and is secured in the suitable bore therefor in the neck A. Formed integral with the base portion of the said neck is the sole of the metal frame, consisting of the forward sole B and the rearward sole C; the upright longitudinal portion of the frame and which is formed integral with the said neck, may be designated as the web D. The frontal sur face of this webis smooth, and seated against said frontal surface, and upon the sole portion B, is a face block E. This fac block may be made of lignum-vitae or of fiber composition, or of any other suitable material, and is secured at its position by screws F and the screws G, passed through the sole B and the web D respectively. The rear side of the web D is hollowed out and there is provided the integrally formed weight piece D. The back block I-I, made of wood, has its forward portion in mortised connection with the web and neck portion of the head frame, and its bottom rests upon and is secured to the sole plate C by cap screws I.

In the frontal face of the said web D are drilled, bottomed and threaded, a plurality of holes J which are symmetrically spaced, and which occupy an area substantially central of the striking face of the head, and of the suitable extent as Shown plainly in Figure 2.

In these threaded holes J, are screwed the impact studs K. These studs are made of fiber -ofclose hard texture and are passed through suitable spaced smooth bores L therefor in the face block E. The body portions of these studs are devoid of threads, their base or bottom portions are threaded and are screwed to tight and bottom engagementwith. the threaded bores in the said web, the purpose being to rigidly retain same there. The impact being against the bottom of the hole, the threads are depended upon only to retain the studs in position. The threads are not depended upon to distribute any pressure. or to withstand any impact A film of glue or cement is provided between the body surface of the studs The face block having been secured at position as hereinbefore described, the ends of the studs may then be cut off and in the finishing of the striking face of the club head, the face of the face block and the ends of the impact studs are flush. These impact studs which considered collectively, are designated in the claims as the impact element, may be embodied in an impact stud of one-piece formation, P, as shown in the modification at Figure 5.

The impact elements or studs, may be Varied in sizes and diameters, and the extent of the area in which same are disposed may also be varied. The essential feature in the seating of these studs in the web D of the head, is that their inner ends are in direct contact with the metal of the said web, so that they act to transmit the force of the head directly to the ball. It is obvious that minor changes may be made inthe shape and. formation of the several parts, and of the several features of my improvements, without departing from the spirit of the invention or sacrificing any of its advantages.

What. I claim as my invention, and desire to secure by Letters Patent, is-

1. A, metal frame golf club head, comprising a longitudinal upright body member, a face block, and a back block secured thereto, and an impact element or element projected from the said body member and through the face block.

2. A metal frame golf club head, comprising a vertical body member having a sole extending forwardly and rearwardly and a neck portion for the shaft, which is in axial lon itudinal alignment with the said body member, a face block and back block secured to said body member and the said soles respectively, an impact element projected forwardly from said body member.

3. In golf clubs of the kind combination with a club head comprising a metal body member which has upright portion and neck shank, there being a weight element formed integral with rear side of said body portion, a face block and back block, and an impact member projected from the central or weighted portion of the body member, and through the face block.

4c. In a golf club of the kind described, the combination with a club head comprising a metal body member which has upright portion and a diagonal neck, the said neck being in longitudinal alignment coincident with described, the V the center line of the said body member, a

being smooth and devoid of threads, and

their inner ends being bottomed to engage the bottoms of the threaded bores therefor in the said body portion, the said impact studs extending through smoothly bored holes therefor in the said face block.

6. In a golf club having a balanced metal head of the kind described, the longitudinal upright body portion being formed integral with the neck or shank, and there being hollows in the back thereof and a substantially central integrally formed weight portion, a face block, and a back block, a plurality of impact studs which are threaded only in the body portion coincident with the weight area thereof, the body surfaces of the studs being smooth and devoid of threads, and their inner ends being bottomed to become seated against the bottoms of the bores in the weighted area of the said body member, and the said impact studs eXtendingthrough smoothly bored holes therefor in the face block.

7. A metal golf club head, comprising a longitudinal vertical body portion, a back block, and a face block, a plurality of impact studs seated in bores provided therefor in the face of said body portion, their inner ends being seated directly in weight transmitting contact with the seats of said bores, the body portions of said studs being smooth and extended through smooth bores therefor in the face block, and whereby the energy carried by the said golf club is transmitted directly through the said impact studs.

8. A metal golf club head, comprising'alongitudinal vertical body portion, a back block, and a face block, a plurality of impact studs screwed rigidly to tight contact with the bottoms of suitable bores therefor in the face of the said body portion, the body portions of said studs being smooth and extended through smooth holes therefor in the face block, and whereby the energy carried by the said golf club head is transmitted directly through said impact studs.
