  1. 1
    I claim:— 1. In a golf club, a shaft, a head having a 45 socket to-receive the shaft end, and a resilient sleeve comprising elastic material wrapped in a series of convolutions at tension, the sleeve being positioned between the walls of the socket and the shaft and exerting a substantial grip- 50 ping effect due to the elasticity of the windings.
  2. 2
    In a golf club, a shaft, a head with a neck portion having a socket to receive the shaft end, and a resilient sleeve comprising a thin strip or thread of rubber wound in a series of con- 55 volutions held under tension on the shaft, the sleeve being positioned between the walls of the socket and the shaft and exerting a substantial gripping effect due to the elasticity of the windings.
  3. 3
    Tn or for a golf club, a shaft having thereon a resilient sleeve comprising a thin strip or thread of elastic material wrapped in a series of superimposed convolutions and held under tension on the shaft and exerting a substantial gripping 65 effect due to the elasticity of the windings.
  4. 4
    In or for a golf club, a shaft having a resilient sleeve comprising superimposed helical windings of elastic material wound under tension in opposite directions on the shaft, said windings being 70 held in a stretched condition on the shaft and exerting a substantial gripping effect due to the elasticity of the windings.
  5. 5
    In or for a golf club, a shaft having thereon a resilient sleeve comprising superimposed T· or the thread 5, or both, may be treated with rubber solution, or other adhesive, in order to cause the thread to adhere to the part 3, particularly at the beginning of the winding operation when a the thread tends to come off. During the winding operation a drag is imposed upon the thread bobbin or other carrier, or upon the thread 5 itself, this ensuring that the thread 5, when wound upon the part 3, is under tension Ί0 and consequently in a stretched condition so that it tends to cling tightly to said part. As shown in Fig. 2 a covering
  6. 6
    6 is provided for the windings and may consist of a coating of rubber solution or latex, of a gutta percha cov15 ering moulded on position, or a thin rubber sleeve which is drawn over the windings 4. The windings 4 and said covering are retained securely in position by metal clips
  7. 7
    7 which are clamped over the ends of the windings the outer surfaces of the 20 rings being below the outer surface of the cover 6 in order to allow the same to contact with the wall of the socket in the club head. As illustrated in Figs. 1 and 2 the windings 4 are truly helical, but they may be wound as illus25 trated in Fig·. 3 where they are obliquely wound or they may be wound after the manner of textile cops where the thread is traversed backwards and forwards during winding, the purpose in both cases being to ensure .firmness, and to prevent 30 their spreading out. In Fig. 4 the part 3 of the shaft I is formed in known manner with a rolled helical thread 8 upon which the thread 5 is wound and which serves to maintain the windings securely in posi35 tion and prevents longitudinal displacement of tilio threOids Fig. 5 shows a modification wherein the windings 4, instead of being wound upon the shaft proper, are wound upon a metal or other ferrule 40 19 which is then fitted upon the end of the shaft and attached by rivets 20 or otherwise. Referring to Fig. 6, the wooden head is formed with a conical or tapered socket or bore 9 which has a reduced part 9α at the sole IO of the club. 45 The end of the shaft I with the wound, elastic sleeve thereon, is driven into the socket 9, in which it becomes firmly wedged owing to the elasticity of the windings 4 and their taper, which the windings assume from the part 3. After the shaft 50 has been sufficiently driven into the head to obtain the necessary grip, the projecting end is cut flush with the sole 10 of the head, and a hole I I, of slightly oval shape, is formed in the part 3 with its major axis at right angles to the axis of 55 the shaft I. A screw nail 12 is then screwed into the club head through said hole in order to secure • the shaft positively in position. The oval shape of the hole 11 is to permit the slight torsional play between the head and the shaft which the elas60 tic wound sleeve provides but if this is not desired the hole is made of the usual circular shape. Fig. 7 illustrates a modified method of securing the shaft and head together. The part 3 is formed with a rolled screw thread 13 in known manner, 65 and is engaged by a screwed ferrule 14, whose head engages a shoulder 15 in the socket 9. By turning the ferrule 14, the shaft can be drawn tightly down! into the socket 9 and firmly secured therein. In order to prevent loosening under 70 impact the thread 13 is preferably left-handed in the case of an ordinary right-handed club, and right-handed in the case of a left-handed club. Referring to Fig. 8, the invention is shown applied to an iron or similar club. The neck 16 of 75 the head is provided with a tapered socket or bore 2,020,679 windings of elastic material wound under tension on the shaft, and outer covering material on said windings which are held in a stretched condition within the covering. δ 6. In a golf club, a head with a neck portion having a socket, a shaft adapted to fit in said socket, a resilient sleeve comprising superimposed helical windings of elastic material on the shaft, wound under tension in opposite directions and 10 securing means at the end of said windings to maintain same under tension on the shaft and prevent unwinding, the sleeve being positioned between the circular walls of the socket and the shaft. 15 7. In a golf club, a shaft, a head with a neck portion having a socket to receive the end of the shaft, a resilient sleeve comprising superimposed helical windings of rubber thread on the shaft wound under tension alternately in opposite di20 rections, clamping members at the ends of said windings to secure same, and a covering member on the outer winding, the sleeve being positioned between the circular walls of the socket and the shaft and exerting a substantial gripping effect 23 on the shaft due to the windings being in a stretched condition.
  8. 8
    In a golf club, a shaft, a head with a neck portion having a socket to receive the shaft end, a resilient sleeve comprising superimposed wind30 tags of rubber under tension on the shaft end and wound obliquely with reference to the axis of the shaft and alternately in opposite directions, the sleeve being positioned between the walls of the socket and the shaft, and exerting a substantial 35 gripping effect on the shaft due to the windings being in a stretched condition.
  9. 9
    A golf club comprising, a metal shaft, a striking head mounted thereon, a neck portion on the head having a socket for the end of the shaft, 40 and a plurality of superimposed coils of rubber wound under tension on the end of the shaft, the coils being alternately wound in opposite directions, and forming a resilient sleeve which acts as a cushioning member between the wall of the 45 socket and the shaft and which exerts a substantial gripping effect on the shaft due to the windings being in a stretched condition.
  10. 10
    A golf club comprising, a metal shaft, a striking head mounted thereon, a neck portion on 50 the head having a socket for the end of the shaft, a plurality of superimposed coils of rubber wound under tension on the end of the shaft, the coils being alternately wound in opposite directions, and a screwed part on the shaft for 55 receiving the innermost coil windings, the coils forming a resilient sleeve which acts as a cushioning member between the wall of the socket and the shaft and which exerts a substantial gripping effect on the shaft due to the windings be60 tag in a stretched condition.
  11. 11
