Improvements in Coin-controlled Mechanism for Automatically
Delivering a Pre-determined Quantity of Liquid.
I, ANNIE ELIZABETH PHARE, of Violet Bank, Spencer Road, South Croydon,
in the County of Surrey, Spinster, 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 a coin controlled apparatus for automatically deliver-
ing a pre-determined quantity of liquid, and has for its object to provide a
machine which will deliver a pre-determined quantity of liquid, such as lemonade,
the operation of the mechanism for effecting the delivery of the said liquid being
consequent upon the insertion of a pre-determined coin in the slot. And in order
that this my said invention may be the more readily understood and carried into
practical effect, reference is hereby made to the accompanying sheet of illustrative
drawings wherein :-
Fig. 1, represents a side sectional view of a machine embodying the essential
features of my invention.
Fig. 2, is a front outside elevational view of the same, while,
Figs. 3, 4, 5, and 6, are views of details of the invention.
Referring to these said drawings in which like letters of reference indicate
corresponding parts throughout the whole of the figures, a represents a measure,
which when the mechanism is in its normal position (as shewn in Fig. 1,) rests
on the bottom of a tank or reservoir c, in which the liquid to be delivered is stored,
by reason of gravity, and represents a tube attached to or formed integral with.
and forming part of the said measure. The aforesaid tank e may be provided
with a convenient device for drawing off the residue, if found desirable.
Attached to the said measure a is a rod or lever b which passes upward at a con-
venient angle, and is hinged or pivotted at b to the top d' of the tank c, containing
the liquid, and then passes still further upward in the same plane to within a
certain distance from the outer casing of the machine, this upper or forward
portion being essentially of flat form, and having provided in its
extremity a slot 62 of convenient size for the reception of slightly less
than half the coin controlling the operation. The upper surface of the said
slot is formed of a hinged plate 63 kept in position by a flat spring b provided
for the purpose. In an aperture or vertical slot d provided in the outer casing
(which latter is of convex form the centre of the curve being the pivot b¹), is
arranged a knob or handle e, which is disposed in guides to permit of it being
capable of travelling up and down the said aperture or slot d. This handle e is
horizontally slotted as at e¹ the whole of its length, and is kept normally at the top
of the aperture or slot by the spiral spring f, this said normal position being
such that the slot e¹ is in a direct line with the slot 62 on the bar or lever b,
but separated from the same by a small space as shewn. The lower end e² of this
slot el is constructed in an identical manner with the slot 62 on the rod b, having a
hinged portion e³ controlled by a spring et.

page_text: In operation, when a coin j is inserted in the slot e¹ in the handle e, it slides
down by reason of the inclination of the said handle until an approximate half of
the coin is in the slot e¹ in the handle e, and the other approximate half is in the
slot 62 in the bar or lever b, thus forming a rigid connection between the handle e
and the said bar or lever b. The handle e is then pulled down, which has the
effect of raising the measure a out of the tank, and as the handle moves down, so
the measure a is tilted up until the contents of the same flow out of the tube a¹
and down a shoot g, whereupon such contents would pass directly out of the tap
or spout h, but for the plate or valve e attached to the rod e pivotted to the
handle e, which plate or valve runs in guides and which, at the first moment that
the liquid begins to flow into the shoot g, covers the aperture in the tap or spout h
and continues to do so, until the handle e has been pulled down to its lowest point.
It is then that the coin in the slot comes in contact with the rigid projection i
which overcomes the power of the springs 4 and et, and forces the coin out and
into a receptacle provided for the purpose, whereupon the measure a and its con-
nections immediately return to their normal position. The handle e having thus
been brought to its lowest position, is released, when the spiral spring f returns
it to its original position ready for the insertion of the next coin. The plate ea
attached by the rod e to the handle e is consequently lifted clear of the aperture ¹
of the spout h, and the measured quantity of the liquid which is now in the shoot!
passes out of the said tap or spout h, and is received by the operator in a vessel
or tankard provided for the purpose. It will be noticed that in Fig. 3, I have
shewn the pivotted lever with its actuating connections in its normal and
operated positions, the better to explain the working of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
CLAIMS.
1. In coin-controlled mechanism for automatically delivering a pre-determined
quantity of liquid, the measure formed with a channel provided at one end of a
pivotted lever, which lever is flat upon its upper side and slotted at its forward
end, such slot being covered by a hinged plate controlled by a spring; in com-
bination with a handle travelling in guides in the front of the machine, said
handle being slotted, while its rear end of which is situated within the interior
of the machine, and reaches to within a short distance of the opposing end of the
pivotted lever, has a hinged upper plate controlled by a spring, substantially as
described and illustrated.
2. The improvements in coin-controlled mechanism, consisting of a tank or
reservoir e, a pivotted lever having at one end a measure a, provided with a
channel a and at the other a slot 62 covered by a hinged plate 63 controlled by a
spring 6, such slot coinciding with a similar slot e² covered with a spring con-
trolled flap in one end of a handle e capable of a vertical movement in a slot in
the face of the machine; the cut off plate or valve e connected to a lever e
actuated by said handle, and a rigid bar i projecting interiorally from the front
of the machine, all arranged, combined, and operating substantially as and for
the purpose described, and as illustrated by the drawings.
Dated this 12th day of December 1898.
