Machinery for Shaping Wooden Golf Club Heads and the like.
I, DANIEL FRASER of 4 Leith Street Terrace, Edinburgh, in the County of
Midlothian, North Britain, Gun and Rifle Manufacturer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be.
particularly described and ascertained in and by the following statement :-
This invention relates to machinery for shaping wooden golf club heads and
the like.
In accordance with my said invention the machine is provided with a metal
pattern of the club head required, from which pattern the cutter of the machine is
guided so that it automatically cuts out or shapes from the blank or block of the.
club wood the exact shape of club head required.
Manual or skilled labour is thus dispensed with; and further the exact shape
required is exactly obtained. Also the shaping can be effected very much more
rapidly than can be effected by hand labour, so that the cost of production is very
materially reduced.
In carrying out my invention, I employ a suitable bed-plate and standards after
the manner of a metal planing machine. The bed has mounted upon it a travelling
table which has two revolving spindles placed side by side, with a back centre
for each. Between the one spindle and its back centre is placed the metal
pattern. Between the other spindle and its back centre is placed the
club head block. Above the said spindle carrying the metal pattern is a guide
wheel or tracer. Above the spindle carrying the club head block is a revolving
cutter.
The said guide wheel or tracer and revolving cutter are carried in the slides of a
framing which is mounted above the bed plate, the said slides being so mounted as
to enable both a vertical and horizontal movement being given to the guide wheel
or tracer and revolving cutter.
But in order that my said invention may be more readily understood and easily
carried into effect, I will proceed to describe the same with reference to the
accompanying drawings, throughout which the same reference letters denote
similar parts.
Figures 1 and 2 are perspective views of my improved machine.
Figures 3 and 4 are elevation and side elevation respectively of the revolving
cutter, and Figure 5 is a view showing how the cutter is driven.
Figures 6 and 7 are elevation and plan respectively of a detail.
Figures 8 and 9 are elevation and plan respectively of a metal pattern, from
which the cutter is guided so as to produce the same pattern of a club head upon
the required block of club-head wood.
Figure 10 is a part perspective view of a modification of said machine. And
Figure 11 is a modification of the cutter driving gear.
Referring to the said drawings I employ a bed plate A having two or more
standards a. On the top side of this bed-plate A. I mount a travelling table or
bed B which is formed with a headstock b into which is fitted the two horizontal
spindles C, D, said spindles being revolved by means of the slotted shaft E which

page_text: is driven by means of spur e and bevel gearing e', from the main or driving shaft F
of the machine. That is to say, I mount by means of a feather a spur pinion e
on the said shaft E; said pinion being carried by a bracket on underside of
headstock band geared into the intermediate spur pinion es which also gears with
the spur pinions c and d of the spindles C and D. The whole arrangement being
such that no matter in what position the table or bed B is in the spindles C and D
will be left free to revolve at equal speeds so as to revolve the pattern and article
being shaped, at the same time.
་
The table B obtains its travelling motion from the main shaft F of the machine
through the medium of the cross shaft et spur e bevel reversing gear e and worm and
worm wheel arrangement B'; said worm wheel being keyed on the end of a small shaft
the inner end of which is provided with a small spur pinion which gears into a spur
rack attached to the underside of the table B, in such a manner that, on the
reversing gear es being operated by means of the reversing lever arrangement e
the table B will be reciprocated backwards or forwards as the case may be.
In order to obtain an up and down movement for the revolving cutter G and
guide wheel H so as to enable them to follow the shape of the pattern, 1 mount
them adjustably in a vertical slide J which works vertically in a horizontal slide J¹
carried by the uprights K of the machine, in such a manner, as to enable the
cutter G and guide wheel H to engage with the pattern and article being shaped
by the weight of the vertical slide J and its connections; said slide J being
provided with any suitable counter balance weight arrangement j, or by means of
a spiral or other spring arrangement acting either above or below the said slide J.
The 'revolving cutter G shown in detail Figures 3. and 4 is preferably formed
with two, three or more suitably shaped knives y which are secured to a central
disc; said disc being connected to the one end of a spindle g¹ (Figure 5) which
has the bevel pinion g keyed on it; said pinion g, gears into a corresponding
pinion g mounted on the lower end of an upright spindle g³ carried by the slide J;
said spindle 9 having a belt pulley G' mounted on it so as to enable the main
shaft of the machine to drive the cutter G by means of the belt f, in such a
manner, as to impart a motion to the cutter G in a vertical and transverse direction
to that of the revolving spindle C, between the grip C¹ and adjustable back
centre c¹ of which the article to be shaped is placed, the pattern being mounted
between the end of the spindle D and adjustable back centre d', in such a
manner as to permit of the guide wheel H running freely over the surface of
the pattern. The grip C₁ on end of the spindle C is provided with two serrated
or toothed jaws ², c (shown in Figures 6 and 7) the top one 3 of which is
formed in the pivotted top portion of the grip which can be bound in position when
desired by means of the binding screw ; the lower jaw c³ is also provided with
a side adjustment screw e so as to enable the work to be set as required. The
back centres c', and d² are carried in the adjustable slide and screw brackets 2
which work in slides in the table B so as to permit of the centres e¹ and ² being
adjusted.
In order that the travelling table or bed B may be travelled backwards and
forwards by the operator, I provide the worm wheel shaft with a friction clutch
hand wheel and lever arrangement B2 which when slackened out enables the spur
pinion to be turned so as to actuate the table B without interfering with any of the
driving gear.
In order to enable the machine to produce the desired shape of club-head I
employ a metal pattern L, as shown in Figures 8 and 9, which, owing to its shape
together with the position of the centre line on which it revolves being equi-
distant from the outer extremities and 12 of the head, gives sufficient strength
and rigidity to the pattern and material, as to enable the most delicately shaped
club head or other like article being shaped or milled. The pattern may be so
formed as to represent any desired kind of golf club head or the like.
The action of the foregoing machine is such, that on the pattern L being placed

page_text: and set between the spindle D and centre d', and the wood, blank or block adjusted
in and between the grip C¹ and centre c', the operator places the reversing-
lever in position and starts the machine in motion by means of the starting-
lever M (Figure 1). This starting of the machine sets the spindles C'and Diand
cutter G in motion, and owing to the guide wheel or tracer H moving freely on
its centre over and around the pattern L, the cutter is caused to shape the article
identical with the pattern L, after which all that requires to be done is to saw or-
otherwise cut off the ends or projections of the article corresponding to those
marked and on the pattern.
I
As a modification I may arrange the machine as shown in Figure 10, that is to-
say, in lieu of the uprights K of the machine for carrying the slides J and J,
employ a pivotted frame P which may consist of one or two arms or brackets the
rear ends of which would be pivotted to the main driving shaft F of the machine..
The said frame P is provided beyond or behind the shaft F with one or more
counter balance levers p and weights p'. The front end of the said frame P is
attached to or provided with the cross piece J2 on which the horizontal slide J¹
works, and the vertical slide J is made stationary the movement being obtained by
the oscillation of the said frame. Or as a further modification, I may dispense-
with the counter balance levers p and weights p', and form the arms or frame P
in one piece with the brackets which carry the main shaft, F, or the arms P-
may be rigidly bolted to the said brackets Q. In either of the foregoing cases I
may employ a horizontal shaft R, Figure 11, for driving the cutter G, said.
shaft R being carried by the frame and driven by the main shaft F, through.
the medium of bevel gearing S, in such a manner, as to drive the cutter G at the
required speed. The said cutter G may be mounted direct ou to the end of the-
shaft R, as shown, or it may be connected and driven therefrom through the medium
of spur gearing. When the said shaft is used in combination with a solid frame,.
that is with the arms or brackets P made in one with the brackets Q, I provide
the said shaft R with a suitable universal or ball and socket joint and sliding-
tube so as to permit of the up and down movement of the vertical slide J.
As a further modification, I may if desired mount the driving pulley G' of the
cutter G in the horizontal position, in lieu of in the vertical position as shown, and
suitably arrange the gearing accordingly.
In some circumstances I may dispense with the grip C' and form the spindle C
similar to the spindle D, and in all cases the spindles C and D may be retained
in their sockets in the headstock b, by adjustable screw pins or studs.
Having now particularly described and ascertained the nature of my said inven--
tion, and in what manner the same is to be performed, I declare that what I
