To all whom ima clot/wem.' i

Be it known t at l, Je ALnxANvnR MCMAHON, a subject of the King of Great- Britain, and aresident of the city of Hamilton, in the county of entworth, Province of Ontario, Dominion of Canada, have invented certain new and' useful improvelll .is the shaft o ments -in Golf Clubs, of which the following is a specification.'

My invention relates to improvements in golf clubs and the method of making same and the object of the invention is to devise a metal construction for the heads of clubs such as drivers, which have formerly been made of wood, whereby a club of superior appearance and greater durability is pron duced, and a further. object is to so construct the metal head, that a ve exact balancing of the club may be readi y obtained.

My invention consists of a golf club having a cast -metal head suitably cored for lightnessl and adapted to receive the shaft, said head provided with inwardly extending orices in the driving face thereof into which are secured hardwood inserts, and provision being made for placing a balancing weightv w1thin the central portion of the head behind-the wooden inserts, all as hereinafter more particularly described andf illustrated in the accompanying. drawings in which;

Fig. 1 is a perspective view of the head of a golf club constructed according to my invention.-

Fig. 2 is a side elevation showing my improved metallic head before the insertion of the wooden inserts, the right hand portion being shown in section.

Fig. 3 is a plan view of Fig. 2, the left hand portion being shown in section on the line 3, 3.

form of the wooden inserts.

Fig. 6 is a perspective view of one of the smaller side inserts.l

Like characters of reference indicate coru responding parts in the diferent views.

1 is my imroved olf club head and 2 the go f club.

The head 1 is cast preferably of an aluminum alloy and is cored at 3 to provide a hollow interior for reducing the weight of the head.

head is provided with recesses extending inwardly thereinto from the driving face 4. Ilhere are three of these recesses consisting of a large central recess 5 and two side recesses 6. The recesses are their axes are parallel.

'llhe large central recess 5 intersects the peripheries of the side recesses 6 and is of greater length than said side recesses.

7 is a partition extending across the hollow interior of the head and forming the rear ends of the recesses, and 8 is a partition extending rearwardly from said partition 7.

9 is a cylindrical hardwood insert which is adapted to be secured within the central recess 5.

10 are cylindrical hardwod inserts each having a groove 11 extending longitudinally thereof.

The inserts 10 are adapted to be secured within the side recesses-6 and the ooves 11 engage the outer peripheral sur ace of the large insert 9. y A 12 is a balancing weight of lead or other suitable material which is carried at the rear end of the recess 5 behind the insert 9.

13 is an u wardly inclined shank or neck portion carrled-by the head and is provided with a taperin orifice 1d into which the lower-end 'of t e shaft 2 en ages. l

l5 is ascrew engaging a t readed orifice vin the shank 13 vand its inner end engages the lower end of the shaft for retaining the head in place u on the shaft.

' l? are core ho es in the partition 7.

After the inserts 9 and 10'are in place their outer ends 16 `are finished and made to ali with the driving face 4 of the head and thus form the greater part of the driving The entire drivin face is suitably serrated after the usua practice.

l-litherto golf clubs of the pattern referred to have been made 'entirely of wood and it has been with a view of overcomin certain objectionable features of these woo en clubs that my invention has been devised.

ln the case of a wooden club in order to maintain same in good condition it is necessary thatI it be scraped and-varnished at frequent intervals, while a very objectionable 'feature of the wooden clubhas been that it splits where the shaft is attached be apparent that both naar cylindrical and E finir lll@ i@ y, adsense tronhles have heen overcome in my clh since after the head has heen properly of the inserts.-

lll

- A further advantage of my head resides in the facility with which a very exact degree of balance may loe readily obtained.

ln the wooden heads orxnerly'used a piece l oi? lead was inserted into the rear faceA oi the head to obtain the desired wei ht.,-y

ln my head however the weig t l2 is placed at the rear end of the recess 5, `hehind.

the insert 9, and is thus located adjacent to the center of gravity ol the head and hy varying this weight 12 any desired' de ree of weight of club may he obtained an at the same time an exact balance of the head maintained. i

A `feature of my construction is the manner in which the central insert 9 interlocks with the side inserts.

From the foregoing it will be evident that ll have devised valuable improvements in golf clubs which will greatly increase their appearance and durahi ity. y

Various moldications may he made in the exact details oi construction without departing from the spirit of the invention or the scope of the claims and therefore the exact form shown is to he taken as illustrative only and not in a limiting sense.

lFor instance the shape and arrangement off the inserts might be altered.

What l claim as my invention is:

1. A golf club comprising a hollow metallic head having the driving face thereof open, a wooden insert carried within the head, the outer lace ol'said insert coinciding with the driving :lace of the head, and

a single rloalancing weight carried within the head adjacent to the center oil gravity thereof' and situated centrally loehind the insert. 2. A. golf club comprising a cast metal head snitahly cored to form a hollow interior and a plurality of intercepting, parallel, cylindrical recesses extending thereinto iron). the driving face thereof, wooden inserts secured within said recesses, the outer ends of said inserts coinciding with the driving face ofthe head, and a balancing weight mounted within the head centrally behind the inserts and adjacent to the centre of gravity of the head.

3. A oli" clnh comprising a cast metal head suitably cored to form a hollow interior and havingl three intercepting parallel cylindrical recesses extending e thereintofrom the driving face thereof, cylindrical wooden` inserts 'secured 'within said recesses, a portion of the side inserts -being cut away to forni longitudinal grooves into which a portion of thel middle insert engages, the outer ends of said inserts coinciding with the driving :tace or' the head, and the rear ends engaging the inner end walls of the aforesaid recesses.

d. A golf club comprising a cast metal head snltahly cored to form a hollow interior and having three intercepting parallel cylindrical recesses extending thereinto from the driving tace thereof, cylin-l -drical wooden inserts secured within said recesses, a portion of the side inserts heing ont away to form longitudinal grooves into which a portion of the middle insert engages, the outer ends of said inserts coinciding with the driving face o the head, the rear ends engaging the inner end walls of the aforesaid recesses, and a counterbalancing Weight situated at the innerend of the middle recesses directly behind the iniddle insert.
