Quantities of Liquid in Exchange for Coin.
I, WILLIAM HENRY PEARSE, of 29 to 31, Ridley Road, Dalston, in the County of
Middlesex, Wholesale Confectioner, do hereby declare the nature of this invention
to be as follows:-
My invention relates to an improved construction of cabinet for containing and
automatically supplying from bulk small quantities of liquid in exchange for coin ;
and consists in the combination of a half-worm on an axle adapted to be rotated from
the outside of the cabinet; a releasing and locking mechanism alternately engaging
with the half-worm for the purpose of locking it in its then position and disengaging
therefrom for the purpose of allowing the shaft of the half-worm to be moved upon
its axis, said mechanism being actuated in one direction by the weight of the coin and
in the opposite one by a counterpoise or its equivalent; a receptacle for the liquid.
fitted with a suitable force pump; to which combination may be added any convenient
type of indicating mechanism for the purpose of shewing the nature of the liquid as
well as whether the receptacle is full or empty.
In carrying my invention into effect, I provide a suitable outer case for containing
the operative parts of the mechanism employed in which case and the frame thereof
and at a convenient relative position therein, I form a slit for the reception of coin,
said slit opening into an incline which is reversed, or has a sudden drop formed in it,
for the purpose of preventing any interference or tampering with the contents of the
cabinet or of its till; and there may be a second opening at which the indicating
tablet can be exhibited. A proper delivery nozzle is fixed upon the case.
Proper means are provided by which access to the contents of the cabinet may be
had for such purposes as replenishing the receptacle, examining it and the mechanism,
or repairing them.
The shaft of the half-worm is provided with suitable bearings, and is fitted with a
winch handle, or equivalent device, by which it can be easily rotated by the
anetomer

page_text: The releasing and locking mechanism consists substantially of the following
devices, and is operated as hereafter set forth.
A lever is provided, having a counterpoise or its equivalent at one end, the effect
of said counterpoise being to raise a detent and to keep it engaged with the descent
of the half-worm. The opposite end is shaped to receive a coin as it drops from the
incline above mentioned.
A second lever is provided which has one end terminating in a half loop standing
normally just under the coin-end of the first lever. The other end of this second lever
engages with a connecting bar the depression of which by a cam revolved with the
half-worm raises the half loop.
I adopt the following device to prevent fraudulent abstraction of the liquid. The
nozzle and external part of the tube are surrounded by a jacket which is perforated,
whereby a communication is established between the outer air and the annular space
between the nozzle and the jacket.
Suitable guides are provided for the purpose of regulating the respective motions
of the several parts. as well as a suitable detent for preventing the shaft of the half-
worm being turned in the wrong direction.
When a coin falls upon the coin-end of the first mentioned lever, the detent is
disengaged from the half-worm; the fall of the coin into the till being prevented by
the loop of the second lever.
The rotation of the shaft of the half-worm depresses the connecting bar, frees the
coin, and actuates the force pump. This force pump connected by its suction pipe
with the receptacle; and by its delivery, with the nozzle. The piston of this pump
is conveniently actuated in one direction by the cam on the worm-axle, and in the
other by a suitable returning spring; but any other suitable mechanism for actuating
the pump as the worm axle is in motion may be adopted.
I may fix more than one set of the above described mechanisms within one case.

I, WILLIAM HENRY PEARSE, of Nos. 29 to 31, Ridley Road, Dalston, in the County
of Middlesex, Wholesale Confectioner, 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 :-
My Invention relates to an improved construction of cabinet for containing, and
automatically supplying from bulk small quanties of liquid in exchange for coin; and
consists of a half worm on an axle adapted to bo rotated from the outside of the cabinet:
a releasing and locking mechanism alternately engaging with the half worm for the
purpose of locking it in its then position, and disengaging therefrom for the purpose
of allowing the shaft of the half worm to be moved upon its axis, said mechanism being
actuated in one direction by the weight of the coin, and in the opposite one by a
counterpoise or its equivalent; and a receptacle for the liquid fitted with a discharging
mechanism; to which combination there may be added any convenient type of
indicating mechanism for the purpose of showing the nature of the liquid as well as
whether the receptacle is full or empty.
For the purpose of preventing fraudulent abstraction of the liquid, the nozzle of the
delivery tube is surrounded by a larger tube the inner end of which is open to the air,
and as the outer end projects for some distance beyond the nozzle, suction cannot be
brought to bear upon the latter.
In order that my invention, and the means by which the same is to be carried into
practical effect, may be thoroughly understood; I will proceed to describe it in detail,
referring in so doing to the accompanying drawings, which are to be taken as part of
this specification and read therewith, and in which
Fig. 1 is a left land; and Fig. 2, a right hand, side elevation, illustrating the
construction and operation of my invention; while Fig. 3 is a detail illustrating a
modified form of discharging mechanism.
A is the cabinet; and, a, the coin slit. B is the frame by which the operative
mechanism is supported. The coin shoot is formed by the conjunction of the two
plates b, b, the inner faces of which have a V groove formed in them, the one opposite
the other. A slot, c, is formed in the side of each groove for nearly its whole length.
This construction of coin shoot is the same as described in my former specification
No. 57881887
D is a shaft adapted to be rotated from the outside of the cabinet in suitable bearings
formed in the frame of the machine. Upon it there is a worm, d, the head of which
is returned to the shaft by a descent, d¹, at about a right angle with the axis of the
shaft.
E is a detent normally engaged with the descent, d². It is pivotted at, e, to a coin-
lever, F, having its fulcrum on the frame, B, at f. 'G is a counterpoise on the opposite
end of the coin lever.
H is a second lever having its fulcrum on the frame at h. Its front, and heavier,..

page_text: end, h¹, is adapted to prevent the coin from dropping from the coin-lever prematurely,
as described in my said former specification No. 57881887, whilst its opposite end,
serves to lift the link, I. This link slides in, or on, suitable guides provided for that
purpose and has a shoulder, i, formed on it for the purpose of being depressed by the
engagement
therewith of a cam, i, on the worm shaft, D.
is a lever having its fulcrum on the frame at, j, and pivottally connected to the
link, I, at j¹.
K is the receptacle for the liquid, which may be placed in any suitable and convenient
position either within or outside the case A; and, K, the suction tube leading there-
from to the body, L, of a force pump, which it enters at a point just below the
plunger, 1, when the latter is at the top of its stroke, so that its down stroke effects
the closure of the suction pipe. I provide a spiral spring, 1, between the head of the
plunger and the body of the pump, for the purpose of returning the lever, J, and
the link, I, to their respective normal positions.
M, is the discharge pipe terminating, if the invention is to be used for the sale of
scent, in a nozzle m, which stops short of the discharge orifice of the ornamental
terminal, n¹. N is a tube-surrounding the nozzle, and having its inner end, n, open
to the air. It is continued through the case, as indicated by the pair of dotted lines
in Fig. 1, and makes air-tight connection with the passage provided in the ornamental
terminal, n, for the delivery of the liquid or spray.
The operation of my invention, constructed as above described is as follows:-
The various parts being in the position illustrated in the figures, when a coin is
dropped into the coin-slit, a, it. rolls down the coin-shoot, and drops on to the front
end of the coin-lever, F. Its weight depresses the lever, raising the counterpoise, G,
and withdrawing the detent, E, from before the descent, d', of the worm, d. The coin
would now drop off the coin-lever, if it were not supported thereupon by the end, h¹,
of the lever H.
The shaft, D, is now turned round to the right, and the cam, , brought to bear
upon the extension, i, of the link, I. The latter is thereby depressed, and the
plunger, 1, driven through its down stroke, discharging a quantity of liquid
proportioned to the said stroke from the nozzle, m which it leaves in the form of spray
in consequence of the compression to which it is subjected by the diminished diameter
of said nozzle as compared with that of the delivery tube, M.
The modification of discharging apparatus illustrated in Fig. 3, consists in the
combination of a pump for discharging air with a force pump as the latter is
illustrated in Figs. 1 and 2, and described therewith and is especially adapted for
delivering a liquid, e.g., scent, in the form of spray.
Lis the liquid force pump; and O, the force pump for ejecting a volume of air
previously inspired through the port 12. P is the air discharge pipe which makes
connection with the ornamental terminal, n', in the same way as described above with
reference to the pipe N, illustrated in Figs. 1 and 2.
The outer end of the discharge pipe, M, is led through the side of the pipe, P,
making air tight connection therewith, and is then bent so as to deliver its charge of
liquid along the centre line of the pipe P ; but its end or nozzle stops short of the
discharge orifice of the ornamental terminal, n'.
As soon as the liquid is discharged into the pipe, P, it is caught by the air blast
therein, and delivered from the terminal, n³, in the form of fine spray.
It will be observed that the pump, O, and pipe, P, will act as a preventive against
the fraudulent abstraction of liquid by suction, in the same way as the pipe, N,
illustrated in Figs. 1 and 2 and described therewith, for if suction be applied to the
terminal, n, only air will be drawn through the port, l, and the pipe, P; for the
mouth of the pipe, M, will be too far within the said terminal to be influenced.
I wish it to be distinctly understood that I do not confine myself to either of
the above described mechanisms for ejecting a volume of liquid.
and
I may fix the receptacle for liquid in any convenient position outside the cabinet,
may also combine several sets of the above described mechanisms for the purpose
of offering a choice of liquids of any kind to the purchaser.

page_text: I have described the shaft, D, as having only one cam, i, upon it, but I may
provide it with two or more cams, each one adapted to engage with and pass the
shoulder, i, once in one revolution of the shaft about its axis. There will of course be
as many discharges of liquid per revolution of the shaft as there are cams about it.
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. The combination of the hereinbefore described releasing and locking mechanisms
adapted to be operated from the outside of the case containing them by the insertion
of a coin and the rotation once round its axis of a shaft on which is fixed a worm with
a suitable device for discharging a definite quantity of liquid, said device being
operated from and by the rotation of the said shaft.
2. The combination of the several mechanisms herein before described with a pump
or other equivalent device adapted to the discharge of a definite quantity of liquid by
the operation of the said mechanisms subsequent to the insertion of the coin
substantially as described with reference to the accompanying drawings.
3. The combination with the tube adapted to deliver a definite quantity of liquid in
exchange for a coin of a pipe of larger diameter encircling the said tube and
practically projecting past the mouth or nozzle thereof the other end of the said pipe
being in communication with the air and thereby adapted to freely pass a current of
air through itself when suction is brought to bear upon the discharge end thereof,
substantially as described with reference to the accompanying drawings..
