PROVISIONAL SPECIFICATION.
Improvements in Coin-freed Liquid Delivering Apparatus.
I, HUGH MANSFIELD ROBINSON, LL.D., of 3, Harcourt Buildings, Temple, in
the City of London, Solicitor, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improved coin-freed mechanism for delivering a given
quantity of liquid in exchange for a coin.
My improved mechanism comprises a measuring vessel preferably arranged
within the supply reservoir and adapted to be placed in communication with the
said reservoir and with a discharge pipe, in such a manner that the measuring-
vessel after having been filled from the supply reservoir may discharge its contents
to the outside of the apparatus.
In practice I find it advantageous to employ a three-way cock for controlling
the filling of the measuring-vessel and the discharge therefrom, the said cock being
so arranged that at no time can communication be established between the supply
reservoir and the discharge pipe. This cock is operated from the exterior of the
apparatus by a handle attached to a slide which is locked in its inward position by
means of a suitable catch. In order to disengage this catch from the slide to allow
it to be drawn out upon the insertion of a coin, I arrange in the slide a slot into
which the coin introduced through the usual aperture drops in such a manner that
the edge of the coin projects above the surface of the slide. As the rod is pulled.
outwards (a little free movement being allowed to permit of this without operating
the cock) the projecting edge of the coin acts against an inclined surface of the
catch and lifts the same. The coin as it drops into the slot in the slide is supported
upon a ledge or shelf beneath it until the catch is lifted by which time the slide
has been drawn so far forwards that the coin is moved away from the ledge or shelf
and drops out through the bottom of the slide and is delivered into the money box.
On the return of the slide the catch again drops into engagement with it.
In some cases I find it advantageous to arrange a spring in conjunction with the
slide so that when the slide has been pulled out and then released the spring will
move it back to its normal or closed position so that the cock shall be in the
required position for filling the measuring vessel ready for the next person.
To prevent the coins from being introduced in the apparatus until the slide is in
the proper position to receive them, I arrange a shutter which, when the slide is
drawn forward, is beneath the slot in the casing and closes it.
I sometimes find it advantageous to combine with my apparatus an arrangement
of double racks and pawls for ensuring that the slide shall be pulled out and pushed
in only once for each single coin.

page_text: I, HUGH MANSFIELD ROBINSON, LL.D., of 3, Harcourt Buildings, Temple, in
the City of London, Solicitor, 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 coin-freed mechanism for delivering a given
quantity of liquid in exchange for a coin.
My improved mechanism comprises a measuring vessel preferably arranged
within the supply reservoir and adapted to be placed in communication with the
said reservoir and with a discharge pipe, in such a manner that the measuring
vessel after having been filled from the supply reservoir may discharge its contents
to the outside of the apparatus.
In practice I find it advantageous to employ a three-way cock for controlling
the filling of the measuring vessel and the discharge therefrom. This cock is
operated from the exterior of the apparatus by a handle attached to a slide which
is locked in its inward position by means of a suitable catch. In order to disengage
this catch from the slide to allow it to be drawn out upon the insertion of a coin,
I arrange in the slide a slot into which the coin introduced through the usual
aperture drops in such a manner that the edge of the coin projects above the
surface of the slide.
In some cases I find it advantageous to arrange a spring in conjunction with the
slide so that when the slide has been pulled out and then released the spring will
move it back to its normal or closed position.
To prevent coins from being inserted into the apparatus until the slide is in the
proper position to receive them, 1 arrange a shutter which, when the slide is drawn
forward, is beneath the slot in the casing and closes it.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a sectional elevation of apparatus constructed according to my
invention:
Figure 2 is a sectional plan of the same:
Figure 3 is a view of parts of the apparatus shewn in Figure 1 but representing
the said parts in a different position:
Figure 4 is a sectional elevation illustrating a modification of my invention;
and,
Figure 5 is a sectional plan of the same:
Figure 6 is a section on the line 6-6 Figure 5.
Similar letters of reference indicate corresponding parts in the several figures.
a is the supply reservoir and 6 is the measuring vessel, c is a three-way cock
designed when in one position to establish communication between the pipes d and e,
connected, as shewn in Figure 1, respectively with the supply tank a and with the
measuring vessel b, and in the other position between the pipe e and the discharge
pipe or spout as shewn in Figure 3.
g is the slide for operating the said cock, the said slide at its rear end being
provided with a stirrup h which engages with a pin ' on the lever c¹ of the cock
and being provided on its other end with an operating knob i. When the slide is
in the position shewn in Figure 1, which is its normal position, communication is
established between the tank a and the measuring vessel b, when, however, the

page_text: slide is pulled outwards to the position shewn in Figure 3 the position of the cock
is altered as hereinbefore described to allow the contents of the measuring vessel
to flow out through the spout. It will be understood that the said cock is so
arranged that at no time can communication be established between the supply
reservoir a and the discharge pipe f
jis the catch which normally locks the slide the said catch being pivoted at kin
the box or casing I surrounding the mechanism and engaging with a notch or
recess m in the said slide. n is the slot in the slide into which the coins introduced
through the aperture o in the casing and filling through the chute p drop, the
said coin being supported upon the shelf g beneath the slot so that its edge projects
above the surface of the slide.
With this arrangement as the slide 9 is pulled outwards (a little free movement
being allowed) the projecting edge of the coin acts against an inclined surface on
the underside of the catch and lifts the same so that the slide can be drawn out.
The shelf g upon which the coin rests is of such length that it supports the coin
until the catch is quite free of the slot m; the coin when the slot is moved
away from the shelf dropping out through the bottom of the slide into a box
provided for receiving it. "On the return of the slide the catch drops by gravity
into the recess m.
It will be noticed that the recess m is made of such a length as to permit of the
outward movement of the slide whilst the catch; is being lifted by the edge of the
coin. In order that this movement, which can be made when no coin is in
the apparatus, shall not move the cock e the stirrup h by means of which the cock
is operated is made as shewn in the drawing so as to permit of the free movement
of the slide.
ris the spring which I sometimes employ to return the slide g to its normal
position so as to ensure that after the measuring vessel has been wholly or partially
emptied the cock shall be placed in the proper position to refill it ready for the
next person.
s is the shutter which is carried by the slide g and which when the latter is drawn
outwards closes the slot o to prevent the introduction of coins.
In the modification of my invention shewn in Figures 4, 5 and 6 the arrangement
of apparatus is similar to that hereinbefore described the main difference being that
the slide instead of having a horizontal movement is fixed to the plug of the cock
and has a rotary movement. The slot n into which the coiu falls is open at one side
instead of at the bottom and the shelf q which supports the coin in the slot until it
has lifted the catch j out of engagement with the notch n is in the form of a rod as
clearly shewn. The spring r is in this arrangement coiled around the plug of the
cock one end being attached to the shell of the cock and the other end to the slide y.
With this arrangement it will be observed that the cock is directly operated by the
lever c¹ fixed thereto.
t is a recess formed in the casing of the apparatus to receive the end of the
lever when in its normal position. Dotted lines in Figure 4 indicate the position
of the said lever when the said cock is open.
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. In coin-freed liquid delivering apparatus the combination with a reservoir for
the liquid, of a measuring vessel below the normal level of the liquid in the said
reservoir, a three-way cock adapted to establish communication between the
reservoir and the measuring vessel or between the measuring vessel and the
discharge spout, and a slide in connection with the lever for operating the said
cock the said slide being normally locked by a catch designed to be disengaged by
a coin, substantially as described.
2. The combination of parts forming the improved coin-freed liquid delivering
apparatus hereinbefore described and illustrated in Figures 1 to 3 of the drawings.

page_text: 3. The modified arrangement of coin-freed liquid delivering apparatus
constructed substantially as described by reference to Figures 4 to 6 of the
accompanying drawings.
