Claims

1. In an adjustable head golf club, the combination comprising;

a club head including a symmetrical ball engaging playing face portion and rear surface portions including a pair of angularly converging surfaces separated by a rearwardly directed protuberance including a vertical surface substantially parallel to said playing face, means defining a blind cylindrical bore of substantially uniform diameter extending longitudinally of said head, a hosel including a stem portion extending within said bore and including portions of first, second and third diameters, each smaller than its predecessor, said first diameter portion of said stem being dimensioned to extend into said bore and engage the wall thereof to provide a sliding fit therewithin, said portion of said stem of said first diameter terminating in a junction with said portion of said second diameter to define a first shoulder therebetween, said portion of said stem of said second diameter extending further into said bore and terminating in a junction with said portion of said third diameter to define a second shoulder therebetween, said portion of said stem of said third diameter extending still further into said bore, a first collar carried by said third diameter portion of said stem and fixed on the end thereof, said first collar including an outer diameter complementary to said cylindrical bore and terminating at one end in a plurality of circumferentially spaced teeth of substantially V-shaped cross-section, a second collar of substantially the same diameter as said first collar and slidably mounted on said third diameter portion of said stem between said first collar and said second shoulder, means securing said second collar to said head and against sliding movement within said bore, but permitting sliding movement of said stem therewithin, said second collar including a complementary toothed portion selectively engageable with the toothed portion of said first collar, spring means encircling said stem between said second collar and said first shoulder urging said collars into engagement with each other, and lock means carried by said protuberance extending into said bore to selectively secure said head and said stem against relative sliding movement.

2. The device of claim 1 wherein said lock means consists of a set screw.

3. A golf club, as defined in claim 2, wherein a lever is provided extending substantially parallel with said head and is connected to said set screw, whereby to rotate said screw.

4. A golf club, as defined in claim 1, wherein said second collar is secured to said head by means of a pin extending tangentially to said second collar.

5. A golf club, as defined in claim 1, wherein said stem is provided with an annular groove, and an O-ring is disposed in said groove for preventing access of moisture into said bore and for retaining a lubricant which is interposed between the bore of the head and the outer surface of the stem.
