But we form the neck and shank of the club head so that it has an integral extension of about double the ordinary or conventional form of tapered shank, and this is accomplished by a plurality of integrally joined stepped cylindrical portions that will preferably although not necessarily be of approximately equal length and which decrease progressively both in outside diameter and in wall -thickness toward the upper end of the elongated shaft, these portions in the drawing being designated respectively by the reference characters I6 to I9, inclusive, I6 being a portion adjoining they normally upper end and enlarged portion I5 of the shank I3, and the respective cylindrical portions I6 Vto I 9 inclusive being stepped downwardly or progressively reduced both in diameter and wall thickness in the manner shown most clearly in Fig. 2, forming a series of peripheral shoulders to 23, inclusive. We have discovered that when the shank is greatly elongated and the elongated portionl is divided up into a series of substantially cylindrical sections stepped down in diameter so as to decrease the wall thickness of the elongated added sections or, portions progressively and upwardly of the shank similar to sections I6 to I9 inclusive, the peripheral shoulders 29 to 23 inclusive have the'effect of damping or absorbing vibrations imparted to the club head in striking the ball, due to the inability of the shank when thus constructed to transmit vibrations of a mechanical nature and high frequency from the head into the shaft, with the result that when the club head and the shank with its elongated and stepped down portions is constructed in the improved manner herein shown and described the club has substantially the feel of the prior wood-handled club in which excessive vibration or ringingr in the handle was of quite frequent occurrence and at the same time, our improved step-down construction in the hereindescribed integral extension on the shank of the club head surrounding the shaft provides an improved symmetrical connection or joint between shank and shaft, permitting the use of suflicient metal in the club shankv to give the club desired balance while maintaining symmetrical and pleasing lines in the design of an iron headed metallic shafted club which has been hitherto the vcause of much experiment and labor without nding a satisfactory solution to the problem on the part of golf club artisans prior to our invention.

The invention as embodied in the improved and integral metallic headed shank shown in both Figs. l and 2, may be employed to advantage with a metallic shaft provided with suitable plating or other metallic finish as illustrated in Fig. 1, under which condition a tubular longitudinally extended socket opening for the shaft II will be formed in the stepped cylindrical portions I6 to I 9 inclusive and extended downwardly in the usual manner into the shankportion I3, Where the same may be locked in any desired manner as by means of an ordinary transverse key or pin. We prefer, however, to utilize a locking device of the form shown in our co-pending application for patent Serial No. 614,346, led May 31,' 1932, to which reference may be had for the details thereof since the specific form of shaft locking or keying device forms 4no part of the present invention, it suiiicing to say that 30 designates a socketed member introduced into the bore of the shank prior to the insertion of the shaft I I, after which when a. shaft is employed of taper form the locking key 3| may be introduced on the inside walls of the shaft and forced to the bottom of the socket opening, where the locking key will expand the slotted portion 32 of the part 30, wedging the shaft tightly in the socket opening of the shank so that it may not be shifted therein nor withdrawn without failure of the joint.

In Fig. 2 a hollow tubular tapered shaft is shown of the same form as the shaft I I of Fig. l, but provided with a suitable-covering or sheath which may be enameled, plastic or other decorative material, and between the sheath or covering ofthe shaft 35 and the upper terminus of the stepped downwardly reinforcing cylindrical portions IB to I9, inclusive, we preferably insert an ornamental band or ferrule 36 for finishing purposes, although the same obviously may be dispensed with and the effect of the same when used may be enhanced for decorative purposes Vby giving the same a covering different from or contrasting with the color of the sheathing or covering material on the shaft. l

It will be seen from thevforegoing description of our invention that we have provided a symmetrical construction and joining between the Shaft and shank of an iron headed golf club, producing a joint that will cushion the shaft of the club against vibrations which would ordinarily be imparted to the shaft by blows upon the club head, and that we have provided an ornamental and symmetrical design of club head and elongated shank, permitting of the addition of such quantities of excess material as may be desired in the shank of the club head for balancing purposes without destroying the beauty and symmetry of the club design adjacent the joint of the head and shaft.

We claim:

l. A golf club comprising an integral head and shank formed of metaL'the shank portion thereof being elongated to substantially twice the normal length and provided adjacent the outer portion thereof with a plurality of integral, axially aligned, integrally joined, substantially cylindrical short tube sections of stepped down or progressively less and less tube thicknesses and outer diameters away from the headend of the shank, there being a longitudinal bore extending through said integrally joined, substantially cylindrical short tube sections and extending into the inner normal shank portion of the club head, and a handle shaft secured in the normal shank portion of said longitudinal bore.

2. A golf club comprising an integral head and shank formed of metal, the shank portion thereof being elongated to substantially twice the normal length and provided adjacent its normal central and its outer extremity therefrom with a plurality of integral, axiallyaligned, integrally joined, substantially cylindrical short tube sections of stepped down or progressively less and less tube thicknesses and external diameters away from the head end of the shank, there being a longitudinal bore extending through said integrally joined, substantially cylindrical Yshort tube sections and into the inner shank portion of normal length of the club head, and a tubular metallic handle shaft secured metal to metal in the normal shank portion of said longitudinal bore.

3. A golf club comprising an integral head and shank formed of metal, the shank portion thereof being elongated to substantially* twice the lengthof the shank of a normal golf club head and being tapered so as to enlarge outwardly from the intersection of the head and shank portion tions imparted to the head short tube sections and into the aforesaid down- Y wardly tapered portion of the shank of the club head, and a tubular metallic handle shaft secured in the inner shank portion of normal shank length in said longitudinal bore within the downwardly tapered portion of the shank and being surrounded metal to metal by the stepped down sections on the shank whereby to dampen vibrathrough the shank to the handle shaft.

4. A golf club comprising an integral head and shank formed of metal, the shank portion therel of being elongated and provided adjacent the outer portion of its extremity with a'plurality of not less than four axially aligned, integrally joined, substantially cylindrical short tube sections of stepped down or progressively less and less tube thicknesses and external diameters away from the head end of the shank, there being a tapered, longitudinal bore extending through said integrally joined, substantially short tube sections and into the shank of the club head, the said bore tapering toward the said club head, Vand a tapered, hollow, tubular, metallic shaft secured metal to metal in the inner shank portion of normal shank length Within said tapered longitudinal bore, the smaller end of said taf pered metallic handle shaft being inserted in the bore whereby to surround and support the said shaft at its weakest point adjacent its joining with the club head by said cylindrical short tube sections of decreasing diameters away from the head end of theV shank and for damping vibrashat where it isV attached in the head.
