' My-present invention relates to improvements in c lub heads for golf clubs or the like, and in particular to a head composed of molded and vulcanized rubber.
Y Clubs such as drivers, spoons and brassiesv are usually s o large in size as to be too heavy when of solid material, for example wood or metal, and it is dilicult to. obtain a4 well balanced one when employing these ma` terials, or to duplicate properly balancedv ones when produced. For this reason at tempts have been made toovercome the disor formin z F1 ure 2; and f advantages by casti-n hollow metal bodies, eadsv with recesses to wooden receive ba ancing weights. v
It is the object of these improvements to produce a readily duplicatable head of homogeneous resilient material of just the right weight and balance desired, by the use ofmoldable rubberv composition which is so vulcanized as toproduce a'- relatively hard but non-frangible body yhaving an in'- yterior o f sponge rubber by means of which the durability and resiliency vor elasticity of such heads is increased, while insuring against thedefect of overwei ht.
The invention therefore resides in the pro-- duction of a novel article of manufacture, and a method of producing the same from rubber. v v In the accompanying ,drawingzv- "Figure 1 isan elevation of a. golf club;- Figure 2 is a top plan view thereofl partly brokenaway; Y, j' Figure 3 is a vsection on thef"l inel3`.3' of igure 4 is a section onethe line ike ,reference characters desi nate corre?-y sponding "partsg throughout f t e /sev'eral`.l
` VIEWS.
I club head Referringvjto the drawing, 1 designatesthe lar stock having'jits end atthe neck of the head i properly` tapered .interiorly to :receive the correspondingly` formed shaft end.'v
,The tube is bent internr'yxediate its` length kand attened preferably so as 'to' prevent the composition frompassing upwardly therey ody andlf2' the 'shaft,receivingl bushing which isf'preferably madeof tubuthrough into thelshaft socket and to provide a more secure anchoring within .y the material.- In the yformation of the head I preferablyproceed in the following man- A sheet of new crude rubber stock which has been properly worked in the conventional mill 'and rolled to suitable predetermined thickness is laced in one section of a two-part mold, t e o posite-or coop erating mold section being,| led 'with a mass of corresponding rubber composition. A se arate mass of this rubber material is now mlxedl with asuitable blowing agent such z v.as carbonate of ammonia, orthe like, and' then laid in the section of the moldcon-V- taining the sheet lining. The complemental Aparts of the mold are now-` close mold subjected to 'vulcanizing heat.
During the heating stage the gas pro andthe y duced by the volatilization of the blowing-` agent expands, causing the s onge-like` i ertin formation of the inner mass of t e rubber. y
composition containing said agentk and ex,-
sucient pressure upon .the sur- I roun ng layer of ru'bbe` lto lnsure a dense outer wall forlthe hollow section of the.l
body. The sponge core in this process be' comes homogeneous' with `the outer wall and gives to the bodya light weight and' superior elasticity.
-`,Owing to the spaces-'or vents within the core'i `provided v`by the "'fsponge Vrubber interig the vulcanizing, canbema-*i' A u es teri; yfacilitated by`V e increase in the the solid portion of the body" tend fto' vent the characteristics of sponge rubber. .'In carrying out the recess above 4de-l scribed, the metallic bus ng which is of heat conductive material, assists materially in transmitting the vulcanizing heat to the interior of the rubber mass. The vulcanizing, therefore, may be said to be carried 5 on slmultaneously interiorly and exteriorly. Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. As a new article of manufacture, a club head composed oflmolded vulcanized rubber composition having a dense outer wall anda porous center yat one side of its median axis.
2. As anew article of manufacture, a club head composed of molded vulcanized rubber composition having a relatively hard, outer wall and a homogeneous porous core havin the characteristics of sponge rubber, sai core being arranged remote from the striking face of the head.
3. As a new article of manufacture, a club head composed of molded vulcanized rubber composition having a dense outer wall and a orous center, and a shaft bushing fixed wlthin the body by the vulcanization of the same, said bushin being arranged at one side of the head an the porous center at the other side.
4. As a new article of manufacture, a club so head composed of molded vulcanized rubber composition having a dense outer wall and a orous center, and a metallic bushing of eat conducting material extending into the solid section of the body. p 5. As a new article of manufacture, a club head composed of moldable vulcanized rubber composition, the body being solid at one side to substantially a median line and having a porous core in the other side of the In testimony whereof I aix my signature.
