COMPLETE SPECIFICATION.
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
he same is to be performed, to be particularly described and ascertained in
nd by the following statement :-
This invention relates to an automatic liquid delivery apparatus which I call
he "Automatic push scent distributor," and which is the most simple and perfect
n action of any apparatus of this kind which has yet been constructed.
In the accompanying drawings,
Fig. 1 is a vertical section showing the apparatus at rest, before the exterior
action which produces the delivery of the liquid has been brought into play.
Fig. 2 is a similar view showing the apparatus when in action, and receiving
(while the exterior action is in force) from the reservoir R, the quantity of liquid
to be delivered.
The operating action is exercised on a push piece arranged like that of an electric
bell, and is produced by the application of the finger at point b, the pressure being
transmitted immediately and directly at its other end a, to the measuring and
delivering mechanism.
The measuring device constituting the principal part of the apparatus, consists of
a cylindrical core a, c, which slides freely in a shell d of bronze or other suitable
material, which is secured by screws (with an interposed washer of leather or other
material to ensure a tight joint) to the plate or diaphragm g forming the bottom of
reservoir R, with which it is in open communication.
When the push piece is actuated by the finger (in the same manner as an
electric bell is operated) the measuring space formed in the core a, c, is brought
into communication with the upper opening of the shell d, and becomes filled
with liquid; upon the finger being removed, a spiral spring (or any other form
of spring acting against the inward movement of the push piece) causes the return
movement of the push piece, and also of the core a, e, so that the opening c in the
latter is again brought over the lower opening n in the shell, and through which
the liquid filling the cavity c and that which has entered the air tube t passes into
the funnel e, whence the liquid flows to the outside of the apparatus.
The air supply pipe t which is of such length that its upper end always extends
above the level of the liquid in reservoir R, and is so situated that same com-
municates with the measuring space c of the core, when same is at the two
extremities of its travel, ensures instantaneous filling and emptying of such space.
A screw v forming the movable end of the space c enables the capacity of such
space to be adjusted with the greatest nicety.
Finally, another screw f, the end of which enters a longitudinal slot forming the
bottom opening of space c, ensures the perfect rectilinear movement of the core a, c,
while at same time it limits its travel in both directions; its position is so regulated
in relation to the openings land n, that the measuring space c can only communicate
with one of such openings at any point in its travel, and never with both at the
same time.
Having now particularly described and ascertained the nature of my said inven-
5 tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The direct operation, without any intermediate parts, of a push piece actuated
from the outside of a liquid delivery apparatus, upon the delivery and measuring

page_text: 2. The combination of a measuring device, with an admission and an escape or
delivery opening.
3. The means for regulating with the greatest nicety the amount of liquid to be
-delivered, by means of a screw v.
4. The means for ensuring the instantaneous filling and emptying of the measuring
space c, by the application of an air tube t.
