Aug. 29, 1961 D. RAINS ET AL GOLF PUTTER Filed Nov. 19, 1959 INVENTORS .Fq/A/s fiMflUL/N ATTORNEY United States Patent 2,998,254 GOLF PUTTER David Rains, 514 N. Florida St, Arlington 3, Va., and Robert M. Dulin, Jn, Manor Club, Rockville, Md. Filed Nov. 19, 1959, Ser. No. 854,170 2 Claims. (Cl. 273171) By way of background, it might be stated that when putting on a slow green, as when the green is wet or the grass of the green is longer than normal, a heavy putter is more effective in executing a perfect putting stroke, while a lighter putter is considered preferable and more effective for the best results when putting on a fast green as when the grass is dry and the grass of the green is short.
It is therefore the primary object of the present invention to provide a golf club or putter wherein the head or blade thereof is provided with a removable weight so that the weight of the club head may be varied, according to the requirements of the individual golfer.
An important object of the invention is to not only provide an adjustable weighting means for a golf club head or blade, but a weight that may be readily and easily removed or replaced without the necessity of using tools for operating the weight securing means, to accomplish the changing of the weightof the club head.
Still another object of the invention is a provision of means for automatically securing the removable weight within the club head, against vibrating or movement within the club head, as the club head contacts the object ball in executing the putting stroke.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawing:
(FIGURE 1 is a side elevational view of the putter blade constructed in accordance with the invention.
FIGURE 2. is an end elevational view thereof.
FIGURE 3 is a side elevational view of the blade, partly in section, illustrating the method of removing the weight.
FIGURE 4 is a perspective view of the weight.
FIGURE 5 is an enlarged sectional view taken on line 5--5 of FIGURE 3.
Referring to the drawing in detail, the golf putter blade or head is indicated generally by the reference character 5 and is of the conventional structure.
The blade or head 5 is provided with a bore 6 extending 2 throughout the length thereof and arranged throughout the longitudinal axis of the blade.
A removable weight is indicated by the reference character 7, and as shown, is provided with a groove 8 formed in the surface thereof, the groove 8 extending longitudinally of the weight. g
The reference character 9 indicates a leaf spring which is mounted within the groove 8 and has one end thereof secured within the groove by means of lug 9, the other end of the spring being slidable under a lug 11. A major portion of the spring is curved as at 10 and extends beyond the surface of the weight so that it will frictionally contact the wall of the bore 6 of the golf club head or blade, firmly securing the weight within the bore, and at the same time holding the weight against vibrations as the golf club is brought into contact with the object ball.
It might be further stated that the weight 7 is preferably of a length slightly less than the length of the bore 6, although it is within the scope of the invention to provide a weight of any desired length, without departing from the spirit of the invention and one which may be contacted by an elongated object such as a golf tee, insented in one end of the bore to force the weight from the bore, against the action of the leaf spring, as indicated by FIGURE 3 of the drawing.
From the foregoing it will be seen that due to the construction shown and described, a golfer may readily convert a putter from a heavy club to a light club, or vice versa, for accomplishing the execution of a perfect putting stroke under various green conditions.
1. A golf club putter embodying a putter blade, said blade having a bore extending throughout the entire length thereof along the longitudinal axis of said blade, the ends of the bore being opened to the atmosphere, a readily removable weight fitted within said bore insentible in said bore at either end of said putter blade, and resilient means on said weight for removably securing said weight within said bore.
2. The subject matter as claimed in claim 1, and said weight having a groove formed in the surface thereof, a curved leaf spring mounted within said groove with the intermediate portion therefor extending above the surface of the weight, said spring frictionally engaging the wall gf said bore, removably securing said weight within said ore.
