improvements in Apparatus for Indicating the Force of a BIOW
other Pressure in Exchange for a Prepaid Coin.
I, HENRY HARINGTON LEIGH, Fel. Inst. P.A., Assoc. M. Inst. C.E., of No. 22,
Southampton Buildings, Chancery Lane, London, W.C., carrying on business as
Phillips and Leigh, Engineers and Patent Agents, do hereby declare the nature of this
invention to be as follows:-
My invention relates to improvements in apparatus for indicating the force of a
blow, or other pressure, in exchange for a coin previously paid into said apparatus ;
and consists in a novel combination of mechanisms, according to which the apparatus
can only be worked if the prepaid coin be of the proper size, and which coin will be
refunded if the force of the blow exceed a certain limit.
In carrying the invention into effect, I provide a suitable case in which the
mechanisms are enclosed, and through which a suitable handle, or buffer, projects,
and which is adapted to receive the blow.
The handle is connected to a slide adapted to slide within the case in the plane of
the blow, and to compress a spring, or springs, of a definite resilience. In the said
slide, I form a hole of a given diameter to receive the coin which is carried forward
by the slide, and so engages with one arm of a bell-crank pivotted on a suitable fixed
axis; the actuation of which crank by said coin unlocks the slide for the purpose of
allowing it to be pushed far enough to compress the spring, or springs, above mentioned.
The other arm of the said crank engages in a notch formed in a fixed plate to which
the mechanisms are chiefly fixed.
If the coin is too small, it is dropped through a hole of a diameter, less than the
proper one, in the fixed plate before mentioned; and therefore fails to unlock the
slide above mentioned.
"

page_text: But when the slide has been unlocked, it can be pushed forward in the direction of
the springs, until a second hole in the fixed plate is uncovered, through which the coin
drops on to a pivotted shoot provided with a bifurcated projection, the arms of which,
one on each side of the said pivot, are adapted to engage in either of two notches in
the slide.
If the pressure exerted, or blow delivered, falls short of a certain limit, the coin
is delivered into the till of the apparatus ; but, if, on the other hand, it exceeds a
certain limit, the slide is pushed further in; and the pivotted shoot tripped by the
engagement of one of the arms of the bifurcated extension with its notch on the
slide and the coin returned to the person using the apparatus.
I provide a suitable mechanism for indicating the pressure or force of the blow
exerted upon the spring, or springs.

Improvements in Apparatus for Indicating the Force of a Blow or
other Pressure in Exchange for a Prepaid Coin.
1, HENRY HARINGTON LEIGH, Fel. Inst. P.A., Assoc. M. Inst. C.E., of No. 22,
Southampton Buildings, Chancery Lane, London, W.C., carrying on business as
Phillips & Leigh, Engineers and Patent Agents, 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 improvements in apparatus for indicating the force of a
blow, or other pressure, in exchange for a coin previously paid into said apparatus ;
and consists in a novel combination of mechanisms, according to which the apparatus
can only be worked if the prepaid coin be of the proper size, and which coin will be
refunded if the force of the blow exceed a certain limit.
The object of my invention is attained by the mechanisms illustrated in the
accompanying drawings, in which
Fig. 1 is a front elevation of the improved apparatus, partly in section, the front
wall of the casing being removed.
Fig. 2 is a plan, partly in section.
Figs. 3 to 8 shew the several working parts in different positions as they are
described hereafter.
Figs. 9 to 11 illustrate a modification of the apparatus.
Similar letters refer to similar parts throughout the several views.

page_text: The whole mechanism is entirely enclosed within a case, while a handle, or
buffer, A, upon which the human, or other, force is exerted, outside the case, transmits
the pressure to the mechanism hereinafter described. This handle A is carried by
arms a, a extending outside the case, and is connected with a slide B guided inside
the apparatus in the direction of the pressure by the lugs i . It is adapted to act
through pistons E, E1, E2, against the springs D D1, D2, of definite resistance. This
slide B is provided with an aperture h, of a given diameter, to receive the coin through
the receiver N, and when advancing towards the said springs, the coin kept in the
aperture of the said slide B advances at the same time, thereby touching an arm G¹
of a bell crank lever G, G¹, which serves to unlock the said slide-piece, and to admit
of its further movement towards the springs. The other arm G of this bell-crank
lever, which is pivotted to brackets upon a fixed plate C beneath the said slide-piece,
engages by a projection in a notch e of the said fixed plate C, which latter forms the
frame of the principal mechanism. In the event of a coin of too small a diameter
being dropped into the apparatus, it falls down through the frame C beneath the
slide, after having passed a hole of a diameter somewhat less than that of the proper
coin, before reaching the arm G¹ of the bell crank lever, which locks the slide B.
The motion of the slide B is stopped by the projection g of the arm G of the bell
crank lever G, G¹ engaging into the notch e of the fixed plate or frame C.
When the bell crank lever G, G¹ is unlocked by means of a coin of the right
denomination, the said slide B can be moved further in the direction of the pressure
exerted upon the handle A, until the aperture h, adapted to receive the coin, coincides
with a second hole 2 in the fixed plate or frame C, through which it falls upon a
balance I provided with a fork H, the arms g, g¹ of which are designed to enter into
either of the two notches b, b¹ of the said slide B. The balance I which provides a
path for the coin duly paid, will be turned by the said slide by means of the afore-
said fork H in such a manner, that the path of the coin will occupy a position which
will either deliver it into the till K, or eject it from the apparatus. When a given
pressure is exceeded, the balance I will occupy the position shown by Fig. 8, when the
coin slips down into a channel K' leading out of the apparatus, and the money will be
refunded as a reward to the strong user, while in the event of this pressure not being
attained, the coin slips on the other end of the balance I then in the position shown
by Fig. 7, and falls into the till K inside the case.
The degree of pressure exerted upon the handle is indicated by a gauge-device,
shown in Figs. 1, 3 and 6, but which does not form part of my invention. The
wedge-shaped edge B° of the slide B bears against a projection d of a bar M, which is
guided on the base plate of the gauge-device by means of the studs t, t¹ and the
slots s, s. This bar is provided with an adjustable arm m, the pin n of which rests
against an arm o of the toothed segment p. By means of the pinion u, the move-
ment imparted by the slide B is transmitted to the mechanism of the gauge-device,
and indicated by a pointer on the dial w. As soon as the handle A is released from
pressure, the spring k bearing against the stud of the bar M will return the hand v
to zero.
The modification shown in Figs. 9 to 11 relates to the coin-receiving and -refunding
devices. Instead of using the balance I, a hopper H¹ is firmly attached by an arm B¹
to the slide B.
When the coin is put in the aperture of the slide B, it drops into the hopper H¹
as soon as the said aperture / coincides with the hole in the fixed plate or frame (
after the arm G of the bell crank lever G G' has been released from the notch e of the
plate C. By the motion of the slide B, the hopper H' moves between the two fixed
plates C and P, the latter being provided with the passages P1 and P2, the former of
which communicates with the till through the shoot K, while the latter is opposite
the upper opening of the shoot K', through which the coin, under certain conditions,
is led out of the apparatus. When the aperture in the slide B is opposite the hole h².
the hopper H has advanced so far, that its lower mouth will be covered by the solid
part of the plate P, between the passages P¹ and P2. In the event of the maximum
pressure being exceeded, the slide B and the hopper H¹ will occupy the position

page_text: ?
illustrated in Fig. 9ª. The mouth of the hopper being then opposite the passage P2,
the coin will drop into the shoot K¹, and be refunded to the user as above described.
If however the maximum-pressure is not attained, the mouth of the hopper H¹ will
not reach that position, and the coin will be kept within the hopper until the pressure
exerted upon the handle is discontinued. On the return of the slide B under the
action of the springs D, D1, D2, into its original position, the mouth of the hopper H¹
will pass the front edge P¹ of the plate P, and the coin will drop through the shoot K
into the locked till in the case of the apparatus.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In an apparatus for indicating the force of a blow, or other pressure, in exchange
for a given coin, the combination of the angle lever G G¹ which is adapted to
unlock the slide B acting upon the springs D, D1, D2, with the balance I provided
with the bifurcated arm H substantially as and for the purpose specified.
2. The combination of the movable slide B provided with the handle A the
pistons E, E, E2, and the aperture h with the springs D, D1, D2, the locking device
consisting of the bell crank lever G G₁ engaging with the notch e of the fixed
plate C, and the coin-conducting device consisting of the balance I engaging with the
arms g g with the notches 6 and 61 of the slide B, all substantially as and for the
purpose set forth.
3. In combination with the movable slide B acting upon the springs D, D¹, D², the
hopper H¹, the stationary plate P provided with the passages P₁and P2 and the locking
device which consists of the bell-crank lever G G¹ engaging with the notch e of the
fixed plate C, all substantially as and for the purpose described.
Dated this 17th day of October 1888.
