SPALDNG & BROS., OF JERSEY CTY, NEW JERSEY, A. CORJORATION F NEW i JERSEY GOLF-CLUB IRON.

To NZZ i12/10m.. t may concern.'

Be it known that I, Hanni' K. B. DAVIS, a citizen ot the United States, and resident o't Holyoke, in the county of Hampden and State oi" Massachusetts, have invented certain new and vuseful improvements in Golf-Club Irons, of which the following is a specification.

My present invention relates to improvements in golf iron heads (other than putters) and aims to provide a head which will have added weight for the purpose of otering the greatest resistance to the shock of the blow or ball impact, and to which weight is produced by a protuberance or bulge on the striking face of the club arranged in such a manner as to minimize faulty strokes which are productive of slices and hooks.

It is well known among golfers that there is a sweet feel in every head. This point moves forward or backward according to whether the head is long and thin, or short and wide. It is the object of this invention to locate that sweet point and to associate it with the extra weighting of the blade referred to above.

It is a common fault with the average golfer in making his stroke, to hit the ball with the club face at an angle other than a true right angle to the intended line of the balls flight; at times the hands are travelling ahead of the head of the club, with the result that the blade at the time of impact is turned out to an angle to the right of the desired line. At other times the reverse happens, the action of twisting the head over so as to have the blade turned to the left, the result of the irst named fault is a ball curving to the right, the result of the second, a ball turning to the lett.

These faults are minimized by 'my improved club head, and at the same time greater driving torce is secured by the means which accomplish such results and without weighting or altering the back Jface oit the club. i

In order that my invention may be better understood, reference is made to the accompanying drawings, in which Figure l is a face view of the head of a golf iron. n

Fig. 2 is a section on line 2-2 of Fig. l;

Serial No. 705,917.

Referring by reference characters to this drawing, the club as a whole is indicated at 5 and is intended' to be representative ot any golf iron other than al putter, such for example driving iron, mid-iron, mashie, and niblic, and the various intermediate clubs. The `driving face la of Vthe club head is provided with a bulging portion a, the highest point ofV which coincides with the proper ball impact point. It will be further noticed lthat this bulging portion is oit part cylindrical shape, with the longitudinal axis thereof running perpendicular to the club face.

In other words, the face of the club is straight at any and all points, taken vertically, and has a convex curved portion a, which would appear the same in every section taken parallel to section 2-2- lt will be not-iced further, that the bulging or convex portion is confined to the club face adjacent the impact point, the remaining portions of Vthe club face eX- tending in substantially straight and slightly inclined lines towards opposite ends of the club head.

The operation and advantages of my improved club in correcting or minimizing faulty strokes resulting in pulls or hooks and slices, will be clear from the diagram, Fig. 4. y

In this figure, arrow line l indicates the path of the club in making a proper shot; line 2, an' exaggeration of the path of travel on aA slice-producing shot; and line 3, a

Vsimilar indication of the path of travel on a hook or pull producing shot, it bein understood that in a slice shot, the Aclu head travels towards the player and in a hook shot, the reverse.

Line A represents the straight tace of a club of customary form in making a proper shot, the lines A and A2, the corresponding positions for slice and hook respectively; while curved line B represents the: position of the curved tace of my improi'fed club head in making a proper shot, and B and B2 the corresponding positions for slice and hookf y vC and C represent the hall inipact points ttor surface lines A and B respectively (slice shots With plain and curved face clubs) and arrow lines A3 and B3 indicate the difference in directive influence on the ball; v In a similar n'ianner C? and C4 indicate ball iinpact points-tor a hook shot, and A4, Bfthe corresponding direction influences.

Referring' toV hallinipact point' C of club facevA", it Will be readily noted that it the club is" drawn towardsv the player, side spin started by' the inclination of the club' Will bein'cras'e'd by such" n'ioveinent with corresponding Gravatar@ in flight..4 In con'- trast With this, it Will be noticed, 'o'nreference to Contact point C on the cnrved-ace, that the angle of' the curve osets' the action of the side spin'.-

A similar action occurs on a hooked or pulled shot, as Will be clear from the diagrani' Having thus described what l claim is y l. A golf iron head having' a' face provided With a ball ii'npact portion which is convex lengthwise of the club' head, and straight vertically thereof.

2. A golf ron'head having a Weight providing bulge on its front face of part cylindrical shape, and extending vertically oi the cluh.

3. A olil iron head having a raised portion on the striking tace thereof extending vertia'lly of the' club head, said tace he ing` rounded 'and the ren'iaining portions of thefcliib face extending ronisaid rounded portion in' slightly inclined planes towards and to the opposite ends of the club.

ln testin'iony whereof, I aix lnv signature.

my invention,

HARRY KIRK BRoWN Davis.
