DEIE DPECIFICATION.
Automatic Liquid Delivery Apparatus.
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 system of automatic liquid delivery apparatus is characterized by the
employment of a pan or bucket for liquids which under the influence of any exterior
impulse is directly actuated so as to open a suitable valve which supplies the
liquid and delivers it outside.
The following description and the accompanying drawing will enable the means
whereby this is effected to be understood.
Fig. 1 is a vertical section through the receptacle and shows the delivery
mechanism actuating a bucket in the form of a shoe.
Fig. 2 is a view of the mechanism actuating the pan or bucket, which is in the
form of a pan or pail, and has a shorter travel.
Similar letters indicate the same parts and the following description applies to
both arrangements, which only differ in the form of the pan or bucket.
The full lines show the position of the movable parts when the apparatus is at
rest and before the exterior impulse to measure out the liquid and deliver it outside
has been imparted thereto, while the dotted lines represent the other position of
such movable parts, when the bucket is filled and in direct connection with the
delivery valve.
In either case the fall on to the plate a of the coin (or token) introduced through
slot f communicates an oscillating movement to the lever o, the effect of which is
to remove the pin r, thus unlocking the catch t, and so releasing the stop c formed
on the body of the pan or bucket d. The latter then under the action of the
counterbalance p rises, turning round the axis i on which it is pivotted; and
remains stationary in the raised position (indicated in dotted lines) by the pin e
catching on the finger b, on the end of lever n, l, which can turn round the axis n,
and is counterbalanced by weight 1.
bucket d, the bottom thereof, or a stop thereon, or a bar m carried thereby (or by
In the upward movement of the pan or
other suitable means) acts upon the rod of a delivery valve h, so as to raise same
to allow the liquid to flow directly into the pan or bucket. When the weight of
the liquid which flows is sufficient to overcome the counterpoise l, the pan or
bucket d descends by turning round its axis i, and empties itself into the funnel
which delivers the liquid to the outside of the apparatus.
g
The plate a has under the action of its counterpoise q resumed its normal position,
o that the pin is in place to ensure the catch engaging stop c, which fixes the
an or bucket d in its lowered position, so that the mechanism is then ready to be
perated again.
In the modification shown in Fig. 2 the form of pan or bucket d and also the
eans for opening the emptying orifice by means of a spherical valves are
odified.
In Fig. 1 the shape of the pan or bucket d is such that the level of the liquid
bes not reach the opening before it descends; when this occurs the liquid forces
e free spherical valves against its seat, and closes all issue until the pan or
cket arrives at the end of its descent, when the blade or knife edge k raises the
herical valve so as to allow the liquid to pass into funnel
9.
In the exceptional case where the contact of the liquid with india-rubber is
material, the spherical valve s may be abolished and an india-rubber tube i fitted
Dino77

page_text: to the exit orifice v, the other end of such tube being connected directly to the
delivery tube leading to the outside of the apparatus.
In the arrangement shown in Fig. 2, the spherical valve s is not free, but
is suspended by a rod (or small chain) from a fork k, so that the pan or bucket in
its upward travel comes in contact therewith and the communication between the
exit orifice and the interior of the pan or bucket d is closed. The latter is
therefore suitably closed, to receive the liquid supplied through valve ; but when
it descends again, in its travel it leaves the spherical valves behind, so that the
liquid can then pass through the exit orifice v into the funnel
g.
This arrangement enables the extent of movement of the parts of the mechanism
to be considerably reduced, so that such parts may be arranged in-a receptacle of
smaller dimensions, such as a bottle, for example.
A counter may be suitably arranged and connected with the mechanism so as to
register the volume delivered.
The quantity of liquid at each operation of the plate a and the pan or bucket d
may be varied by adjusting the weight of counterpoise I, and by its position in
relation to the axis of rotation n.
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 principle of the invention described, consisting in the action of operating
by means of a coin or token inserted from the outside of the apparatus, or by means
of a knob, handle, drawer, etc., a pan or bucket, to enable same to rise towards a
suitable valve, which it opens so as to receive a fixed but adjustable quantity of
liquid, which it afterwards delivers directly outside the apparatus.
2. The mechanism suitable for securing the result described in Claim 1, with
the modifications thereof described and shown, to enable the emptying of the pan
or bucket to be effected either (Fig. 1) by means of a free spherical valve, or by an
india rubber tube, or (Fig. 2) by means of a suspended spherical valve, the latter
modification having the effect of reducing the displacement of the movable parts, so
that the mechanism can be enclosed in a receptacle of small dimensions, such as a
bottle, for example.
