ATTORNEY United States Patent O 25,427 STEEL POWER-CENTER GOLF BALL .lack Harkins, Chattanooga, Tenn., assignor to Professional Golf Company, Chattanooga, Tenn., a corporation of Tennessee Original No. 2,914,328, dated Nov. 24, 1959, Ser. No. 739,741, .lune 4, 1958. Application for reissue Nov. 22, 1961, Ser. No. 155,247
5 Claims. (Cl. 273-230) Matter enclosed in heavy brackets [Il appears in the original patent but forms no part of this reissue specilication; matter printed in italics indicates the additions made by reissue.
This invention relates to a golf ball and more particularly to a golf ball having a novel type center, designed to give the ball a longer and more stable course in the air and on the ground. This application is a continuation-inpart of my application Serial Number 616,297, filed October 16, 1956, and since abandoned, for a patent on a Power-Center Golf Ball.
Heretofore, the conventional golf ball [consisted of] included a spherical capsule containing liquid forming the core of the ball. The core was encased in a thick-walled solid rubber spherical casing. The rubber casing was then wrapped with rubber thread and encased in a tough outer core of a rubber compound. According to United States Golf Association Rules, the maximum weight of the golf ball is 1.55 ounces and its minimum diameter is 1.68 inches.
A golf ball according to the invention comprises a relatively small spherical steel core, on uninterrupted homogeneous solid rubber spherical casing of uniform appreciable thickness tightly enclosing the steel core, rubber strands wrapped tightly around the rubber casing, und an outer cover tightly encnsing the rubber strands.
One object of this invention is tio provide a golf ball meeting the above requirements and having more accuracy and stability in flight, bounce and roll, and an increased range.
Another object is to provide a golf ball having a reduced `tendency to slice or hook.
A further object of this invention is to provide a golf ball which will maintain its spherical shape during use throughout its life and can never be knocked out of round or deformed, in `contrast with other golf balls heretofore known, which in use are soon knocked out of round.
Still another object is to `provide a golf ball having a core approximately four times heavier than the conventional liquid capsule core now in use.
A still further object of this invention is to provide a golf ball having a core consisting ot a solid sphere of tempered spring steel.
Other objects and advantages of the invention will be apparent from the following description, taken in conjunction with the drawings, in which.:
FIG. 1 is a view of the outside of the golf ball `made in accordance with this invention; and
FIG. 2 is a section taken along the line 2 2 of FlG. l, with the exception of the spherical core, which is shown solid.
Referring now to the drawings in more detail, the golf ball made in accordance with this invention and generally designated 10, comprises a solid spherical core 1l, preferably made of tempered spring steel. This core 1l is approximately in diameter and is about four times heavier than the core, such as a liquid or water capsule, used in conventional golf balls. The core [i9] 11 is encased in a solid relatively dense rubber spherical center p0rtiOn of casing 12 of substantial thickness. Wrapped around the rubber casing 12 in a manner well-known to the art, are a plurality of strands or threads of rubber [thread] 13.
"ice
Tightly enclosing the rubber strands 13, also in a manner well-known to the art, is a tough cover 14 of a rubber compound having spaced shallow spherical segment recesses 15. The tempered spring steel core 11, the hrm and compact rubber casing l2, and the cover 14 are all concentric with each other in order that the centers of gravity of all the parts will coincide with each other at the center of the ball 10.
Because the solid tempered spring steel spherical core 11 gives the golf ball 1l) a center which is heavier, `with concentrated weight, more compact and more resilient than any other golf ball heretofore known, the ball is capable of a longer and truer tlight and more accuracy on the greens. The solid unsoft rubber casing 12 about the core Il is capable of resisting forces tending to deform it und holds the core hrmly in position against the impact of a golf club on the cover 14, the core being held immovably in its central position during impact of thc golf club und thereafter by the rubber thread wrapping 13 and the solici rubber casing l2. The increased weight `of the ball 10 reduces the chance of deviation in Hight caused by wind and other forces acting on the ball, such as those `forces caused by slicing and hooking. Also when the ball 10 has reached the end of its ight. the novel tempered spring steel center 11 causes the ball to bounce and to roll farther and straighter than a golf ball having a core or center formed from a liquid capsule. The novel tempered spring steel core 11 gives the ball 10 the ability to resist compression more effectively and prevents the ball from being knocked out of round during its lite, while still retaining resilience l0r a live feel, in contrast with other golf balls now or previously used, which in use are soon knocked out of round.
It is contemplated that the use of a golf `ball such as that made in accordance with this invention will improve and make more interesting the game of golf by enlivening and speeding up the pace of the game. The golf ball which is capable of longer and more stable flight will make the igame more enjoyable and aid the morale of the player. Because of the improvement in range and stability and the reduction of hooking and slicing ofthe novel power-center golf ball 10, an unnecessary amount of time will not be wasted in trying to find lost balls; the movement of players on a crowded course will be accelerated; and the number of strokes and errors committed by those not so skilled in the game and by those who play the game occasionally for enjoyment will be reduced.
lt will be apparent to those skilled in the art that various changes may be made in the invention, without departing from the spirit and scope thereof, and therefore the invention is not limited by that which is shown in the drawings and described in the specification, but only as indicated in the appended claims.
