COMPLETE SPECIFICATION.
Automatic Apparatus for Delivering Variable Quantities of Liquids.
I, PHILIPPE LEONI, of 12 Boulevard Magenta, Paris, France, Inventor and
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 automatic liquid delivery apparatus differs from all those hitherto employed
inasmuch as that without any change whatever in the adjustment of the parts of
which it is formed, such apparatus will deliver variable quantities of liquids
according to the weight of the coin (or token) which is used to actuate the
apparatus.
All apparatus of this kind now in use are only capable on the contrary of
delivering an unvarying measured quantity of liquid, which can only be increased
or diminished by differently adjusting the mechanism.
In the accompanying drawings:-
Fig. 1 is a longitudinal section of my improved apparatus provided with a valve
directly connected to the mechanism.
Fig. 2 is a similar view of the same apparatus provided with a grooved valve
made separate from the mechanism.
The same letters indicate corresponding parts in both and the following description
is applicable to both figures, which only differ in the form of delivery valve
employed.
In both arrangements the mechanism turns round the axes o, e, carried by a
transverse part t attached by screws to the diaphragm d forming the bottom of the
liquid reservoir R, which occupies the upper part of the receptacle (of bottle form),
the lower part thereof receiving the money.
The blow on the plate a of a coin or token inserted in the slot causes the lever a, o,
to turn, the extent of such movement depending upon the weight of the coin or
token, while at same time it can be regulated also by the screw p, which by the
9 is fixed in its adjusted position.
nut
e,
The effect of the oscillation of the lever is to cause the lever b, e, to turn on its
axis
such lever b, e, being on the one hand connected by its end 6 to lever a, o,
and on the other hand to the valve e, which as soon as the oscillation begins is
raised from its seat so as to allow the liquid to flow into funnel n, then into the pan
or bucket 9, and so outside the apparatus, so long as the oscillation lasts; but as
soon as lever a, o, returns to its original position it ceases to act on lever b, e, and
the flow of liquid terminates.
The duration of the oscillation, and consequently the quantity of liquid delivered,
therefore, for a given adjustment of the parts, depends on the energy of the impulse
imparted to the plate a (by the weight of the coin inserted in slot f); but for a
similar external impulse different quantities of liquid may be caused to be delivered
by modifying the extent of movement by changing the position of certain parts of
he mechanism.
In Fig. I this is effected by means of the spiral spring (the first turn of which
s secured to the transverse part t, while the last bears on the nut of screw v, by
which the tension of the spring can be adjusted at will, and the point of which screw
pears on the tail end of lever b, e,), or by any other form of spring serving to cause
he end 6 of lever b, e, to bear on the rounded point of screw p, so as to increase or
liminish the friction of the two parts. The differences in the amount of this
riction, which is further supplemented by causing the screw p to project to a
maller or greater extent beyond the head 1, affect the freedom of motion of the
ever a, o, and consequently, therefore, the extent of motion is increased or

page_text: diminished; it follows that the valve c which is rigidly attached to lever b, e,
remains raised from its seat for a longer or shorter period, and consequently permits
the liquid to flow through funnel n into the pan or bucket g for a longer or shorter
time.
In Fig. 2 by the displacement of screw p (which forms a counterpoise), the
distance of which from axis o affects the freedom of movement of lever a, o, for a
given impulse imparted to plate a, the duration of the movement imparted to lever b, e,
by pins, may be increased or diminished; it follows that the free valve c remains
raised for a longer or shorter period, and consequently allows the liquid to flow
through-funnel-n-into the pau_or_bucket g_for a longer or shorter time. With
regard to the actual quantity of liquid delivered by the valve c per second, this
depends on the section of its grooves; but this does not constitute an indefinitely
variable adjustment.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The utilization of the oscillation of a lever (produced by the insertion of a
coin or token through a slot from the outside of the apparatus) to open a suitable
valve, which allows the liquid to be delivered to flow as long as the oscillation lasts,
such oscillation (as well as the delivery of the liquid) being adjustable through the
parts of the mechanism, and being variable for the same adjustment, proportionately
to the energy of the impulse imparted by the fall of a coin or token upon such
lever.
2. The mechanism for effecting the result set forth in Claim 1, and also the
modifications described and shown for the delivery of the liquid either (Fig. 1) by
means of a valve connected to the mechanism and always moving therewith, or
(Fig. 2) by means of a free valve which is only in contact with the actuating
mechanism during the delivery.
