IMPACT INDICATOR FOR. GOLF CLUBS
Michael J. Plese, Brooklyn, N. Y.
Application July 15, 1935, Serial No. 31,396
3 Claims.
My invention relates to improvements in golf
clubs or sticks and more particularly has refer
ence to and is illustrated in the accompanying
drawing in its application to a golf club provided
5 with means in the head thereof for measuring the
impact or blow to determine the distance a ball
will travel when struck; the same being espe
cially useful in practice indoors where the ball
can be driven against a net, padding or other
wise.
Referring to said drawing, I have illustrated
in Fig. 1 in perspective, parts being broken away,
a suitable application of my invention.
Fig. 2
is a longitudinal sectional view of the same on
line 2-2 of Figure 1, Fig. 3 is an enlarged lon
gitudinal section of the indicator and its mount
ing. Fig. 4 is a plan view, looking down upon the
top of the head of the club. Fig. 5 is a view look
ing in at the‘button or disk which receives the
20 impact of the ball. Fig. 6 is a perspective view
of the same, and Fig. 8 is a view of the outer
cylinder or casing within which the parts shown
in Figs. 5 and 6 slide.
8 indicates the hammer or head of the golf
25 club, and 9 the shank where the handle is at
tached. The club is cut away at the top as in
dicated at Hi, to allow for the movement of the
pointer or indicator ll, and I2 is a slide or cover
which may be open or provided with a trans
30 parency at I3 to reveal the scale shown below.
A hole is bored in the head 8 as indicated at
I4 to receive the plug 15, which in turn may be
secured by the screw IS, the plug having a re
duced threaded portion ll, to receive the thread
ed outer shell l8 within which is slideably mount
ed the button or piston 19, resiliently projected
by the compression spring 20 against the annular
flange or stop 2!.
The button or piston portion 19 is provided
40 with a bracket 22, which moves therewith in slot
(C1. 265-—22)
the button l9 and the spring 20 is compressed,
the inward travel of the piston I9 carrying the
bracket 22 which strikes the right end 23 of the
pointer ll, thereby indicating upon the scale l3
the force of the blow or impact. ‘
The nut 30, shown to advantage in Fig. 3, is 5
turned down sul?ciently so that there is enough
friction upon the pointer ii to hold it in the
position to which it is moved by the impact, so
as to indicate the reading upon the scale I3 be
fore the nut is released for the next drive.
Of course, it will be understood that mod
i?cations may be made in the construction and
0
arrangement of parts without departing from
the spirit of the invention, as claimed.
I claim:
15
1. In combination with a golf club, a spring
projected piston therein, said piston having
means projecting laterally thereof, a pivoted
pointer and a scale visible from the outside of
said club, said pointer movable in the path of
movement of part of said means whereby when a
ball is struck by said piston said pointer is moved
by the latter and indicates the striking force of
the blow.
2. In combination with a golf club, a spring
projected piston in the head of the club, a piv
oted pointer and a scale visible from the outside
of the club, lever means connecting said piston
with said pivoted pointer to engage the same,
said pointer being pivoted so as to engage said 30
lever means in" the path of movement thereof
and means for adjusting the position of said
pointer on said scale, said lever means being dis
posed so as to permit the pointer to remain in
indicating position until reset by said adjusting 35
means.
3. In combination with a golf club, a spring
projected piston therein, lever means projecting
laterally from said piston, a pivoted pointer and
[8' to operate the rear end 23 of the pointer ll,
preferably mounted at 25 as shown to advantage
in Figs. 3 and 7. It will be seen that the threaded
shank 25 is screwed into the head of the club,
45 after which the pointer H is dropped over the
upward extending pin 21, around which is se
a scale visible from the outside of the club, said 40
pointer being pivoted so as to engage said lever
means in the path of movement thereof, and.
means for manually adjusting the position of said
pointer on said scale, whereby when a ball is
cured the compression spring 28, which when the
housing 29 is pressed down, is adapted to re
ceive the nut 30, thus pivotally holding the
50 pointer ll freely to turn thereon.
In swinging the club, the ball may be struck by
said lever means to indicate the striking force
of the blow, the pointer remaining in said in
dicated position until manually reset to the in
struck by said piston, said pointer is moved by
itial position.
