Application filed May 23,

Our invention relates to golf clubs.

It is the object of ourinvention to provide a poured lead insert weightfor a golf club, which. when poured, will be interlocking with the golf club, and will not become loosened therein.

It is the object of our invention to provide an insert of lead me wooden golf club head so arranged that no attaching means 18 necessary. 7

It is a further object to provide an attaching means over the poured lead insert of such a character that the insert becomes a strengthening member as wellas a weightin member for the golf club.

Feferring to the drawings; I Figure 1 is an elevation of the golf club head with the lead insert in position;

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is an elevation of the golf club head with the cavities for the reception of the lead shown ready to receive it;

Figure 4 is a side elevation of the pouring ladle pouring the lead into the cavities in the golf club head, the golf club head being shown in section to illustrate the form of the cavities;

Figure 5 is a plan view showing the lead insert after it has been molded.

Referring to the drawings in detail, 1 is a golf club head of any desired form or size in one side of which there has been bored a pair of inwardly converging, diagonally disposed, screw threaded cav ties 2 and The outer ends of these cavities are enlarged to form chambers 4 and 5, which chambers have their axes in line with the screw threaded portions 2 and 3 so that the respective chambers 4 and 5 are tilted at an angle with respect to one another. Each of these chambers is provided with an outward- 1y extending ears 6 and 7 while they are connected together by a narrow flat bridge 8, which is relatively deep in the direction of the movement of the club when striking the ball.

Thus, when lead is poured into these cavities in the golf club head, there will be provided a pair of screw threaded, inwardly converging members, which will engage that portion of the wooden head designated 9 bet-ween them.

This serves to grip the lead weight in the 1927. Serial No. 193,669.

wooden head so that it cannot become loosened. The screw threadcd'lead fingers 'weights 12 and 13 which are provided with extending ears let and 15 and are connected together by the semi-circular and relatively narrow and deep bridge 16. The insert has a the screw threaded interlocking members, the weighted heads and the connecting bridge so that a truss-like structure is formed that willbe retained permanentl in position without movement in the heat.

The lead is poured into the wooden form in molten condition and therefore each insert adapted itself to the irregularities of the cutaway portions of the head with the re sult that no diiliculties are experienced in trying to fit predetermined sizes of cavities and predetermined sizes of lead inserts one to the other, which is a disadvantage of the premolded lead insert, which must be placed in position and attached by some means.

The ladle for pouring the lead is diagrammatically illustrated and numbered 17. The stream of molten metal 18 is poured into the wooden form and allowed to cool and therefore becomes an integral part of the club head. I

It will be understood that we desire to comprehend within our invention such modifications as may be necessary to adapt it to varying conditions and uses.

Having thus fully described our invention, I

what we claim'as new and desire to secure by Letters Patent, is:

1. In a golf club, a wooden head having converging cavities and a narrow commimicating passageway between said cavities below the surface of the head, and a Weighted member inserted therein in molten condition whereby it is interlocked therein.

4. In a golf club, a wooden head and a molded metal insert consisting of inwardly eonvergin metalliescrewthreadedtnenibers and a bri ge connecting said memhers,-enlarged heads on .-sa-id screw threaded naem berof greater diameterethan. said; bridge.

5. In a golf club, a wooden head and a molded metal insert consisting of inwardly convergin metallic screw threaded members and a bridge connectin=g sait1 members enlarged heads on said screw threaded members of greater diameter than said bridge,
