Improvements in Coin Freed Apparatus for Enabling a Supply of
Water or other Liquid to be obtained.
:-
I, RICHARD JAMES STREATFEILD, of Rossington Hall, Bawtry, in the County
of York, Esquire, do hereby declare the nature of my invention to be as follows:-
The object of my invention is to provide means whereby a predetermined
quantity of water, or other liquid, can be obtained on the insertion of the proper
coin, or the like, into the apparatus, the arrangement being such that only the
proper predetermined quantity of water, or other liquid, can be obtained for the said
coin or the like. According to my invention I provide a cistern, or other vessel
capable of containing the amount of water, or liquid, to be drawn off for each
payment. At the side of this cistern, or vessel, is a box, or casing, enclosing the
mechanism which is freed by the coin, or the like. This mechanism consists of
a device which when in one position engages and locks the inlet valve for water,
or liquid, to the cistern, or vessel, and leaves the draw-off valve free to be operated;
and when in another position engages and locks the draw-off valve and releases
the inlet valve for water, or liquid, to the cistern, or vessel, so that water, or liquid,
cannot flow into the cistern, or vessel, except when the draw-off valve is closed.
The said device is brought into the last named position by means of a coin, or the
like, inserted into the apparatus and caused to act upon the said device. I do not
limit myself to precise details but the following is a suitable arrangement of
mechanism for the purpose of obtaining a supply of water from a cistern.
The cistern is filled by means of an ordinary ball cock, to which is attached
a disc with a recess in it to admit a projection from the upper arm of a two-armed
lever, which is so acted upon by a spring as to cause the said pro-
jection to engage with the said slot when the ball is raised and the
valve closed so that the ball is prevented from descending even when the
water falls, and thus water is prevented from entering the cistern. The other
arm of the lever is formed so as to be capable of engaging with a recess in a disc
secured to a rod passing up into the box, or casing, from the draw-off tap and
working with it. It can only so engage however when the draw-off valve is
closed, as if the draw-off valve is not turned off, the slot in the disc connected
therewith will not be opposite to the tail of the lever and the latter will be held in
position by the edge of the disc so that the ball-cock will not be released. Thus
water cannot flow into and out of the cistern at the same time. To effect the
movement of the lever by a coin I provide a wheel in which a slit is cut across the
edge large enough to hold the coin so as to leave a part of it projecting. The coin
is inserted in a slot in the box or casing and conveyed by a flat tube, or passage, to
the said wheel the axis of which is carried through the side of the box or casing
and is there provided with a lever handle.
Supposing that the cistern is empty but the ball cock is held up by the engage-
ment of the lever with its disc; -to obtain a supply of water the draw-off tap is
turned off so that the slot in the disc in connection therewith comes opposite the

page_text: force of the
tail of the lever. On a coin being passed into the slot therefore in the box or
casing it will slide down into the slit in the edge of the aforesaid
wheel so
that, when the lever handle is turned, the projecting part
of the coin presses against the lever overcoming the
spring and releasing the ball-cock. The coin after passing the lever
falls into the bottom of the box and the lever handle when released drops
back into its original position so that the wheel is ready to receive another coin.
As soon as the coin ceases to press on the lever the force of the spring is again
asserted on the lever but until the cistern is full and the ball floats up the lever
is kept in position by the edge of the disc on the ball valve, thus locking the
draw-off cock, until the water rises to its full height in the cistern when the
floating up of the ball will bring the slot in the disc connected therewith into such
a position that the nose of the lever enters the said slot so as to lock the ball cock
and the draw-off valve is at the same time released so that the contents of the
cistern can be obtained.

Improvements in Coin Freed Apparatus for Enabling a Supply of...
Water or other Liquid to be obtained.
I, RICHARD JAMES STREATFEILD, of Rossington Hall, Bawtry, in the County
of York, Esquire, 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:-
The object of my invention is to provide means whereby a predetermined
quantity of water, or other liquid, can be obtained on the insertion of the proper
coin, or the like, into the apparatus, the arrangement being such that only the
proper predetermined quantity of water, or other liquid, can be obtained for the said
coin, or the like. According to my invention I provide a cistern, or other vessel,
capable of containing the amount of water, or liquid, to be drawn off for each
payment. At the side of this cistern, or vessel, is a box, or casing, enclosing the
mechanism which is freed by the coin, or the like. This mechanism consists of
a device which, when in one position engages and locks the inlet valve for water,
or liquid, to the cistern, or vessel, and leaves the draw-off valve free to be operated;
and when in another position engages and locks the draw-off valve, and releases
the inlet valve for water, or liquid, to the cistern, or vessel, so that water, or liquid,
cannot flow into the cistern, or vessel, except when the draw-off valve is closed.
The said device is brought into the last named position by means of a coin, or the
like, inserted into the apparatus and caused to act upon the said device. I do not
limit myself to precise details but the following is a suitable arrangement of
mechanism for the purpose of obtaining a supply of water from a cistern.
I will explain it with reference to the accompanying drawings wherein Figure 1
is a side elevation, and Figures 2 and 3 vertical sections, respectively shewing the
mechanism in the position in which water is being supplied, and the position
when the coin has acted to release the inlet valve and lock the draw-off valve.
Figures 4 and 5 shew details separately.
The cistern A. is filled by means of an ordinary ball-cock C, to which is attached
a disc c with a slot, recess, or notch, c², in it to admit a projection d, from the

page_text: upper arm of a, two-armed lever 1, centered at d³, which lever is so acted upon
by a spring e, as to cause the said projection d, to engage with the said slot, recess,
or notch, c, when the ball is raised and the inlet valve closed as shewn .in
Figure 2, so that the ball is prevented from descending even when the water
falls and thus water is prevented from entering the cistern.
The other arm of the lever, D,. is.formed at d², so as to be capable of engaging
with a recess, or notch, g in, a. disc. G, (shewn separately in Figure 5) secured to a
rod f, passing up into the box, or casing B (which encloses the mechanism and
protects it from being tampered with), from the plug. f,. of the draw-off valve F,
and working with it when it is operated by the handle f.. The part de can only
so engage, with, the notch g however when, the draw-off. valve Fis closed, as,.. if
the said draw-off valve be not turned off, the recess or notch g in the disc G will
not be opposite to the tail of the lever D and the latter will be held in position
by the edge of the disc G so that the ball cock C will not be released. Thus water
cannot flow into, and out of, the cistern A at the same time. To effect the move-
ment of the lever D by a coin I provide a wheel H. (shewn separately in plan and
side view in Figure 4) in which a slit, or recess h, is cut across the periphery
large enough to hold the coin i, so as to leave a part of it projecting as shewn in
Figure 3. The coin is inserted in a slit in the box, or casing, B, and conveyed by
a flat tube, or passage 62, into the recess in the said wheel H, the axis of which
is carried through the side of the box, or casing, B, and is there provided with a
lever handle h2.
Supposing that the cistern A is empty but the valve C is held in the closed
position by the engagement of the projection d, of the lever D, with the notch c³,
in the disc c; to obtain a supply of water the draw-off tap F, is turned off
so that the slot g in the disc G, in connection therewith, comes opposite the tail d³,
of the lever D. On a coin being passed into the slot 6 therefor in the box, or
casing, B, the said coin will slide down the passage 62, into the recess h, in the
wheel H, so that, when the lever handle 2 is turned, the projecting part of the coin
presses against the lever D as shewn in Figure 3, overcoming the force of the
spring e, and releasing the valve C. The coin, after passing the lever D, falls into
the bottom of the box B, and the lever handle h2, when released, drops back into its
original position, where it is held by a stop h³, so that the wheel H, is ready to
receive another coin.
As soon as the coin ceases to press on the lever D the force of the spring is exerted
on the lever, but, until the cistern A is filled with water and the ball floats up, the
lever 1 is kept in position by the edge of the disc c, on the ball valve C, thus
locking the draw-off valve F by reason of the end of the lever D still engaging
in the notch g in the disc G, but when the water has risen to its full height in the
cistern A the floating up of the ball will bring the notch in the disc c into
such a position that the projection d, of the lever D, enters the said notch c³, so as
to lock the ball valve C and the draw-off valve F is at the same time released by
the end of the lever D leaving the notch g in the disc G so that the contents of
the cistern A can be drawn off.
Instead of the spring e a weight can of course be used as the equivalent.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:-
