An Apparatus for the Delivery of a Given Quantity of Liquid in
Exchange for an Equivalent in 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 an apparatus for delivering or supplying a given quantity
of liquid on the insertion in the apparatus of a coin or coins or the like of the proper
denomination.
For this purpose I adapt to any suitable measuring tap or fluid meter an
arrangement whereby in its normal condition the tap or meter is held locked, but on
the insertion of a coin or coins or its or their equivalents in an aperture or apertures
or receptacle adapted to receive the same the aforesaid tap or fluid meter will be
unlocked or released and will deliver or supply a definite quantity of the liquid
contained in the supply vessel and when such quantity of liquid has run out the tap or
meter will automatically cease to deliver more fluid until the insertion of another coin
of the predetermined value.
In a suitable arrangement for carrying out my invention the coin or its equivalent
can be caused to unlock a lock and the person wishing to use the machine will then be
enabled to turn a cock or valve and allow the liquid to flow until the given quantity
has been supplied and on the closing of the cock or valve it will be again locked and
cannot again be operated until the insertion of another coin or its equivalent.

Exchange for an Equivalent in Coin or the like.
I, PERCIVAL EVERITT, of 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:-
This invention relates to an apparatus for delivering or supplying a given quantity
of liquid on the insertion in the apparatus of a coin or coins or the like of the proper
denomination.
For this purpose I adapt to any suitable measuring tap or fluid meter an
arrangement whereby in its normal condition the tap or meter is kept closed but on
the insertion of a coin or coins or its or their equivalents in an aperture or apertures
or receptacle adapted to receive the same the aforesaid tap or fluid meter can be
opened and will deliver or supply a definite quantity of the liquid contained in the
supply vessel and when such quantity of liquid has run out the tap or meter will
automatically cease to deliver more fluid until the insertion of another coin of the
predetermined value.
In order to enable my invention to be fully understood I will describe the means
employed by me for carrying it into effect most advantageously though it is obvious
that modifications may be made therein to meet special requirements or the nature of
any particular case in which it is desired to use the invention.
In the accompanying drawings figure 1 is a vertical section of an apparatus
constructed to allow of a given quantity of liquid being obtained in exchange for an
equivalent in coin or the like according to my invention; figure 2 is a front elevation
partly in section, the section being taken on the line A B of figure 1; figure 3 is a
horizontal section on line C-D of figure 1. Figure 4 represents a modification of my
apparatus in which a series of vessels are arranged for delivering different liquids.
Figure 5 is a vertical section taken on the line E F of figure 4. Figures and 7 are
horizontal and part vertical sections taken respectively on the lines G H and I J of
figure 5. Figures 8 and 9 represent a detached plan and elevation of one of the
blocks or locking pieces hereinafter described used in conjunction with the apparatus
described in figures 4 to 7. Figures 1 to 3 are drawn half full size, and figures 4 to 9
a quarter full size. Similar letters in all the figures represent similar parts.
Referring to figures 1 to 3, A represents a measuring tap or fluid meter of any
suitable construction and adapted to deliver a fixed quantity of liquid each time it is
operated, this tap being in communication with a supply of liquid in a vessel B, by
means of a pipe C, and with the air space in such vessel by means of a pipe D;
E represents the nozzle of the measuring tap A which nozzle forms a continuation of
the plug of the tap which in its normal condition is kept closed as shewn in the
drawings; a, is a handle fitted loosely upon the plug of the tap and b, is an arm or

page_text: lever fixed to the said plug by means of which handle and lever the tap can be opened
by the application of a coin or the like in the manner hereinafter described; c, is the
aperture for the coin or the like to enable the tap to be opened, the said aperture
being formed in a semi-circular portion d, of the casing of the apparatus; the
handle a,
and lover b, are each provided with a slot, which slots e, and fare
co-incident with each other and with the coin aperture c, when the handle and lever
are in the position shewn in the drawing, that is to say, when the tap is in its normal
or closed position; the handle a, projects through and works in a slot g, in the part d,
of the casing and except when locked to the lever by a coin (represented in dotted
lines in figure 1) inserted through the aperture c, will if operated rotate freely on the
plug of the tap A without operating the same; when however it is so locked to the
lever by a coin it will if operated carry with it the lever b, and rotate the plug of the
tap so as to open the same; h, is a plate for preventing the coin from falling out of
the slots e, and f, until the handle a, has been moved sufficiently far to fully op
open the
tap; i, is a shoot which conducts the coin into the bottom j, of the apparatus when the
handle a is commenced to be moved back, the latter then carrying back with it the
lever, in any suitable manner such as by bearing against a pin k, thereon.
By this construction it will be obvious that, the handle a, being in the position
shewn in figure 1 and in full lines at figure 3, in order to obtain a measured quantity
of the liquid contained in the supply vessel B, a coin of the proper denomination must
be dropped through the aperture c, when it will fall into the slots e, and f, and thereby
lock the handle a, and lever b, together; by then moving the handle a, into the
position shown in dotted lines at figure 3, the tap A will be opened and will deliver its
contents when such contents have run out the tap A will (by reason of its
construction to which no claim is made) automatically cease to deliver more fluid ;
upon the handle a, being moved back into the position shewn in full lines in the
drawing the coin will fall down the shoot i, into the apparatus and the lever b, will be
also moved back by the means herein before described and the parts will be in position
ready to again open the tap A. (which will be refilled from the supply vessel B) upon
the insertion of another coin in the aperture c.
When more than one liquid-delivering tap or the like are arranged together I
sometimes prefer to use the arrangement shewn in figures 4 to 7 whereby only one
receptacle for the coin or token is used and any-one (but only one) of the taps can be
released by it. In order to effect this I attach to the handle a, of each tap A (which
handles are fixed to the plugs of the taps) a pointed bar or rod 4, which has a taper
end, which passes between and serves to actuate sliding blocks m, m, as hereinafter
described. These blocks are caused to abut against each other at the lower part m', of
their ends by a weighted lever m², and are prevented from being separated, except
when a coin has been inserted in the apparatus, by a stop n, which can be moved
away or released on the application of the said coin acting through a lever o, to which
the stop n, is attached. The action is as follows: When a coin inserted through the
money slit c, has passed into a bucket p, at the end of the lever o, the stop n, is moved
away. Either of the handles a, a, of the taps A A can then be turned as the sliding
blocks m, m, will allow the pointed end 1, of the rod Z, attached to any one of the
handles a, a, to enter between its two adjacent blocks m, m, and thus allow the said
handle of the tap to be turned. When one handle has been turned it is impossible to
move another handle until the first one has been moved back as will be obvious.
The sliding of the blocks m, m, and the action of a weight y, cause a rack T, to be
moved by a wedges, on one of the sliding blocks m, m; this rack depresses a
projection t, and thereby moves away a pivotted block u, on which the coin rests, the
latter then falling out of the bucket p the stop will when the tap is closed move
back to its original position and thereby lock all the taps A A until a fresh coin is
placed in the apparatus.
The arrangement of pointed bars 1, and sliding blocks m, herein referred to form a
portion of an invention which is the subject of an application of subsequent date
No. 15,699 of 1886 the Complete Specification of which is not yet filed.

page_text: It will be obvious that instead of using a series of vessels as just described one only
of such vessels can be used alone.
I have described and illustrated two forms of apparatus, one in which a coin is
caused to lock or fix a handle to the plug of the measuring tap, and the other in which
the coin releases the mechanism which allows of the handle being operated, these being
means of carrying out my invention which I have found to answer well, but it will be
obvious that the apparatus could. be arranged to be operated by a coin or its equivalent
for the herein stated purpose in various other ways. For example the coin or its
equivalent can be caused to unlock a retaining device such as a lock and the person
wishing to use the machine will then be enabled to obtain access to or to turn a cock
or valve and allow the liquid to flow until the given fixed quantity has been supplied
and on the closing of the cock or valve it will be again locked and cannot again be
operated. until the insertion of another coin or its equivalent.
It will be obvious that various forms of measuring arrangements can be used in
connection with the action of a releasing or unlocking coin. For instance a pump
may be used so arranged that on the insertion of a coin the handle of the pump is
made free to work and on being operated is caused to deliver a given quantity of
liquid again when larger quantities of liquid are required to be delivered any form
of apparatus generally known as a water meter or liquid measurer. may be used, it
being so arranged as to allow an inserted coin to release or unlock a suitable retaining
device and deliver a fixed quantity of liquid.
In reference to a pump an india rubber ball may be so arranged as that when
pressed it will induce a current of air and throw a spray such as is thrown by
ordinary spray delivering scent bottles.
It is also obvious that the apertures of the delivering parts of the supply apparatus
may be contracted if necessary so as to concentrate the issuing stream and form an
automatic fountain delivering scent as a jet or spray or delivering disinfectant or other
liquids.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed 1 declare that what I claim is :-
1. The combination with a suitably constructed measuring tap, of mechanism such
as is herein described and illustrated in the accompanying drawings whereby a fixed
quantity of liquid can be obtained on the insertion, in a receptacle provided for the
purpose, of a proper coin.
2. The combination of parts forming the apparatus for the delivery of a given
quantity of liquid in exchange for an equivalent in coin or the like as hereinbefore
described and illustrated in figures 1, 2, and 3 of the accompanying drawings.
3. The modification of the apparatus as herein before described and illustrated in
figures 4, 5, 6, and 7 of the accompanying drawings.
