ATTORNEIS Patented July 31, 1934 1,968,627 BALANCED GOLF CLUB HEAD "Leonard A. Young, Detroit, Mich. Application December 31, 193-1,sonar-Natures 4 Claims.

This invention relates to golf clubs and more particularly to the construction of the heads of golf clubs.

The present invention relates more particularly .5 to the distribution of weight or to the balance of club heads of the blade type which are of extended width and limited thickness. Some players desire a club head of this type which is so balanced that a predominance of its weight is at 101 its lower side or edge, while other players prefer to have a major portion of weight at the upper side or edge of the head. To meet these requirements, the present invention relates to a bladelike head so constructed as to provide for the location of a major portion of the weight adjacent the lower side edge of the head or adjacent its upper side edge as required, without any material change in the construction.

More specifically, the invention provides a golf club head of this type including a shell and a body within said shell, said body comprising parts, certain of which may be formed of a material lighter in weight than the other or others, so that these parts may be conveniently arranged 25. within the head to give the desired balance to the head.

With the preceding and other objects and advantages in view, the invention consists in the novel construction, arrangement and combina- 301 tion of elements, all as hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawing in which;

Fig. 1 is a front elevation of a golf club con- :'-5j structed in accordance with the present invention;

Fig. 2 is a transverse section substantially upon the line 2--2 Fig. 1;

Fig. 3 is a front elevation with portions broken away and partly in section, of a modified form of the construction; and

Fig. 4 is a transverse section substantially upon the line 44 of Fig. 3.

Referring to the construction in detail, more particularly as shown in Figs. 1 and 2, the club head comprises a thin outer shell 5 of concavoconvex form in cross section and which shell is formed with the usual tubular extension or hosel 6 to receive the lower end of the club shaft '7. The concave or head portion 5 of this shell is adapted to receive a filler body formed, preferably, of two parts 8 and 9 united along their adjacent sides, which sides preferably meet along a longitudinal median line of the club head and are externally shaped to snugly fit within the concave of said shell, said parts presenting through the open side of the shell, the usual flat golf ball striking face for the head.

In the construction shown in Figs. 1 and 2 the lower half or part 8 of the body is formed of a material'which is relatively light in weight, such as aluminum, while the upper part 9 is formed of a heavier metal. As shown, particularly in Fig. 2, the parts of the filler block are interlocked at their abutting edges along the longitudinal median line of the head, by providing a tongue 10 on the upper edge of the lower part 8 to engage within a groove 11 in the abutting edge of the upper part 9 and the two parts are preferably permanently united in any well known manner, as by welding said tongue within said groove. The filler block or body is firmly seated and held within the shell in any suitable manner, but preferably by means of a thin layer 12, such as rubber or other suitable material which isvulcanized or otherwise secured to the inner surface of the shell and the outer surface of the block and also serves as a slightly yieldable shock absorbing medium between the block and the shell. The filler block or body is further secured within the concave shell by turning the edges 13 of the shell surrounding the open side of the shell, inwardly over the edges of the block into an edge groove therein, so that this edge flange 13 will be flush with the face of the block.

The modified construction shown in Figs. 3 and 4, shows the heavier part 9 of the block located at the lower side of the club head and the lighter part 8 at the upper side. Also in this construction, the adjacent or abutting edges of the two parts are formed with corrugated or interfitting sinuous surfaces 14 which are suitably united by welding or otherwise. In this construction the open side of the shell is at the rear side of the club head and this shell is formed with a flat front wall 15 which forms the face of the head, the filler block parts 8 and 9 seating with their flat sides toward this wall and with a thin strip of elastic material 16 interposed between said wall and flat side of said block members and securely united thereto by vulcanizing, or other means. The two parts 8 and 9 are further permanently secured to the shell or wall 15, by turning the edges 17 of this wall rearwardly over the edges of said block parts, the convex surfaces of which parts, in this instance, forming the rear face of the head.

Obviously other changes may be made in the construction and arrangement of parts without departing from the spirit of the invention, and such changes are contemplated.

Having thus fully described my invention, what I claim is:-

1. A golf club head of the blade type having a forward ball contacting face and comprising two parts interlocked along the longitudinal median line of said face, said parts being of unequal specific gravities.

2. A golf club head of the blade type having a forward ball contacting face of extended length and height and comprising two parts interlocked along a longitudinal median line of said face, said parts being of unequal specific gravities, and a thin shell formed to embrace and hold said parts.

3. A golf club head comprising two parts contacting with each other along a line extending longitudinally of and midway between the upper and lower edges of one face of the head, one of said parts having a groove and the other having a tongue extending into said groove, said parts being of unequal specific gravities, and a thin sheet metal shell to receive said parts and having edge portions formed over edges of said parts to hold the same.

4. A golf club head of the blade type including a shell having a substantially flat forward face portion, and a pair of weight members disposed behind and contacting said face portion and meeting along a line extending lengthwise of and midway between the upper and lower edges of said face, said members being of unequal specific gravities.
