PROVISIONAL SPECIFICATION.
Improved Golf Club Head.
1, WILLIAM CURRIE Juur., 6 Strathearn Road, Edinburgh Scotland India
Rubber Manufacturer do hereby declare the nature of this invention to be as
follows:-
My improved golf club head consists of a hollow metal head the same shape
as the wooden ones at present in use, and containing inside one or more of the
following substances, india rubber, balata and gutta percha, ordinarily the india
rubber, balata and gutta percha is vulcanised in the manuer well known to india
rubber manufacturers but this is not essential. 1 prefer to add one or more of the
following substances ground cork, sawdust, wood pulp, rags, asbestos or any
pigment to the india rubber, balata and gutta percha but they are not absolutely
necessary. The metal forms a kind of mould open in the face of the head, which
is then filled up with the composition described above, so that in playing with the
head the ball is hit by the composition. I do not confine myself to any particular
shape of head, but will use that shape which I find the best. To fix the head as
above described on to the wooden shaft, I propose to use the method which is at
present used by all golf club makers for fixing on cleek and iron heads namely by
means of a socket which forms part of the head. This seems to me the best method
but I do not confine myself to it.

SPECIFICATION.
Improved Golf Club Head.
I, WILLIAM CURRIE, Junior of 6, Strathearn Road Edinburgh in the County
of Edinburgh India-rubber Manufacturer, do hereby declare the nature of this
invention and in what manner the saine is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to golf-clubs which are used in playing the game of golf.
Hitherto the heads of these clubs have been made chiefly of wood forming part
of, or being fixed upon, a wooden shaft. Some of the heads have been weighted
at one side with lead or other alloy or metal, whilst others have had fixed on their
underside, or sometimes on the face or playing side, a plate of iron, steel, or brass.
Yet another form of head has been constructed entirely of solid iron, steel, or brass,
fixed to the wooden shaft by a socket.
My invention consists essentially of a golf-club head of metal, such as brass
malleable iron, steel, or the like,-hollowed or chambered out into one or more
compartments said compartment or compartments being filled with an elastic
composition which yields to a slight extent as the golf-ball is struck by the club and
then rebounds again. The invention will be fully described with reference to the
accompanying drawings in which
Fig. 1 is a side elevation of the playing side of a head constructed in accordance
with my invention.

page_text: Referring more particularly to Figs. 1 to 4, A is the wooden handle (part broker
off) by which the player weilds the club, connected to the head B by a socket or
tubular piece b. The head B is made of brass, iron, steel or the like, preferably
brass, hollowed or chambered out into one or more compartments C into which
is placed and secured a filling of elastic composition D.
The filling that I prefer to use is composed of one or more of the following
substances, namely: india-rubber, balata or gutta-percha or mixture of them.
These substances or materials, or either of them, may be vulcanised in the manner
well known to manufacturers of these materials. I would; however, remark that
the materials may be used in an un-vulcanised state if desired. I prefer, when
making up the filling composition to add one or more such substances as ground or
granulated cork, sawdust, wood pulp, rags, asbestos, or the like or any of the usual
pigments known to commerce though neither the substances named
or the
pigments are absolutely essential. In order that the composition shall not be too
rigid it may be made softer in the interior than the exterior.
The filling composition may be fixed in the metal head B by cement or by
förming projections or spikes on the interior surfaces of the head, round which
the composition would be run, or yet again by forming grooves in or upon such
interior surfaces.
Referring now to Figs. 5 & 6, the head here shown only differs from that shown
in Figs. 1 to 4 in that the casing of metal is much narrower.
It will be understood that the metal casing which receives the composition may
be constructed in many ways without departing from the nature of any invention,
for instance a number of holes might be formed in it and filled with plugs of
elastic composition, the only point to watch being that the casing should be made
sufficiently strong to withstand the force of the blow of the club on the golf-ball
and yet be as light as possible.
The advantages of constructing golf-club heads in the manner hereinbefore
described I consider will be that the head will have a greater effect on the ball
whilst at the same time it is less liable to be cracked or broken.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. A golf-club head constructed of metal, such as brass, malleable iron, steel or
the like hollowed or chambered out into one or more compartments to receive
an elastic composition substantially as and for the purposes described.
2. A golf-club head constructed of metal such as brass, malleable iron, steel
or the like hollowed or chambered out into one or more compartments to receive a
composition of vulcanised or unvulcanised india-rubber, balata, or gutta percha,
or mixture of them with or without the admixture of the materials or pigments
specified substantially as described.
3. A golf-club head constructed substantially as described and shown either with
reference to Figs. 1 to 4 or Figs. 5 to 6 of the accompanying drawings.
Dated this 1st day of February 1892.
