An Apparatus for the Automatic Delivery of a Given Quantity, oI
Liquid on the Insertion in the Apparatus of a Coin or the like.
I, PERCIVAL EVERITT, of No. 47, Cannon Street, in the city of London, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements on the invention described in my former
application for a Patent No. 8403 of 1886, the present improvements having for object
to provide a simple arrangement whereby upon a coin being inserted a fixed quantity
of the liquid will be automatically delivered without it being necessary to operate a
tap or other device.
For this purpose the liquid to be delivered 'is contained in a holder provided with a
close fitting piston or in an india rubber or flexible bag .or collapsible vessel or in a
separate vessel that is in air tight communication with either of the above so that on
a weight being applied the liquid is forced out through a suitable orifice.
The weight is held up by a suitable trigger or ratchet or the like which on a coin
being inserted is released so as to allow it to fall a predetermined 'distance and thereby
force out or deliver the liquid.
It will be obvious that instead of a weight a spring can be employed!

Liquid on the Insertion in the Apparatus of a Coin or the like.
I, PERCIVAL EVERITT, of No. 47, Cannon Street, in the city of London, Engineer,
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 improved apparatus, so constructed and arranged that upon
the insertion of a coin or the like it will automatically deliver a predetermined
quantity of liquid without its being necessary to operate a cock, tap or other
device.
In order that my said invention may be understood I will describe apparatus for
delivering a given quantity of scent in the form of a jet or spray although it is to be
understood that it is equally applicable for delivering other liquids.
In the accompanying drawing
Figure 1 is a front elevation of the said apparatus.
Figure 2 is a plan of the same, the upper part of the case being removed to show
the internal mechanism, and
Figure 3 is a vertical section on the line a, a Figure 1, part of the mechanism being
in elevation.
a is the case and stand of the apparatus having the lid or cover and the door c for
permitting access to the interior of the said case. As shown the case is of octagonal
form but it is obvious that it may be of any other suitable shape.
d is the holder or reservoir for containing the liquid to be delivered, which reservoir
is suitably mounted within the case and provided with a filling tube e and with
openings, g for a purpose hereinafter described.
1 is a pump cylinder located in the opening g and supported upon the block i secured
to the under side of the reservoir.
In this block are formed a channel j for establishing communications between the
interior of the reservoir and the cylinder, and a channel k, for establishing
communication between the cylinder and the discharge pipe having at its outer
end the delivery nozzle 1. As shown in the drawing this nozzle is adapted to deliver
the liquid in the form of a jet in an upward direction so that the said liquid may he
directed into a handkerchief or other article held over the nozzle. ¹, 2 are valves
placed in the channels, respectively and operating in a well known manner in
conjunction with the piston.
m is a cup or shield placed beneath the nozzle to catch any falling drops of
Hamid

page_text: This
n is a pump piston or plunger which works within the cylinder h and which is
connected by the rod n' to a crank-pin o attached to a disc o¹ upon a shaft p.
shaft is supported in standards p', p² attached to a formed integral with the top of the
reservoir. It will be understood that the diameter of the cylinder and the stroke of
the piston correspond to the quantity of liquid to be delivered at each revolution of
the crank-disc. Instead however of using a pump of the kind herein before described
I may use any other form of liquid meter.
y is a pinion mounted upon the shaft p and engaging with a gear-wheel q¹ loosely
mounted upon a sleeve bereinafter described rotating upon a shaft 2 journalled in
bearings in tlie standards "", 7.1
s is a barrel also mounted upon the shaft 72 and having wound upon it a cord st
passing through the opening fand carrying a weight 2. t is a ratchet wheel secured
to or formed integral with the said barrel and working in conjunction with a spring
pawl on the gear wheel so that when the barrel is rotated owing to the action of
the weight s the gear wheel will be rotated therewith, and communicate its motion
to the pinion g and thence to the crank-disc o¹ and the piston n.
u is an escapement supported between the standards p², p³ and normally in
engagement with the pin on the disc o to prevent the latter from being rotated.
This escapement has an elongated boss u² carrying an arm 3 connected by a rod u
to one arm of a double armed lever us supported in standards ', u'. The other
arm of the lever carries a bucket arranged to receive the coins
or the like
inserted through the slit win the case of the apparatus. This bucket arrangement
forms the subject of a separate patent No. 10231 of even date with this patent.
Although I have described the use of a weight for operating the pump it is to be
understood that a spiral or other spring may be substituted therefor.
The operation of the apparatus hereinbefore described is as follows, that is to say:
When a coin or the like inserted through the slit w falls into the bucket » its
weight causes the depression of the lever, the motion of which is communicated
through the rod to the escapement to remove the same out of engagement
with the pin u' on the disc o. The latter is then free to rotate under the action
of the weight 2 in the direction indicated by the arrow Figure 3, whereby the
piston n is operated to deliver liquid. The movement of the escapement in the
imanner hereinbefore described places its pallet * in the path of the pin in such a
manner that after the disc has performed a portion of its revolution the said pin
impinges against the said pallet and return the escapement together with the
bucket v to their normal position (the coin in the meantime being discharged
from the bucket in a well known manner) the rotation of the disc being thus
stopped after it has made one revolution.
In order to facilitate the return of the escapement and bucket to their normal
position the lever is provided with an extension a carrying a counterweight.
The lever is prevented from rising too high by means of a pin on a
standard or by any other suitable means. In order to raise the weight after it
has run down I construct the barrels with an elongated bossy carrying a hand
wheel y¹ by means of which the barrel may be rotated to wind the cord thereon.
During this rotation of the barrel the teeth of the ratchet wheel slide past the
pawl
To prevent the rotation of the gear wheel 7' in a backward direction owing to
friction, provide the pawl = which engages with the teeth of the said gear-
wheel.
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. Coin freed liquid delivering apparatus adapted to automatically deliver a
predetermined quantity of liquid upon the insertion of a coin without the necessity
for operating taps, cocks or other devices.
2. In a coin freed liquid delivering apparatus the combination with a reservoir
of a pump or other liquid meter adapted to draw liquid from the said reservoir and

page_text: deliver the same through a suitable spout or nozzle, the said pump being operated by
means of a spring or weight the operation of the pump being controlled by means of
an escapement, the movement of which to release the spring or weight.is effected by
the weight of a coin acting to depress a lever or levers in connection with the said
escapement.
3. The improved coin freed apparatus for delivering liquid consisting of the parts
constructed and combined substantially as described with reference to the
accompanying drawing and operated as set forth.
