COMPLETE SPECIFICATION.
Improved Apparatus for Drawing Off and Checking a Measured
Quantity of Liquid.
I, EMILE HIRSCHI, of Pontenet, in the Republic of Switzerland, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
-
The object of this invention is to provide an apparatus for drawing off and
checking a given quantity of liquid. The apparatus is illustrated by way of
example, in the annexed drawing in which Fig. 1 is a plan of liquid measuring
apparatus constructed according to this invention, Figs. 2 and 3 are plan and
elevation of a pivotted spring catch, on an enlarged scale, Fig. 4 is a vertical
section along the line - Fig. 1, and Figs. 5 and 6 are elevations of the record-
ing dial and counting mechanism.
The apparatus consists substantially of a receptacle R of any given capacity,
furnished with a double-seated outlet valve S S₁ on the rod T of which is also
a valve for the taking in of the liquid. The rod T is actuated by a lever L
pivoted at a. A spring keeps the valves S S tight and brings the lever back
to its position of rest. A tube A communicating with the external air is provided
in the lower part with a small valve or valve clack C made of some light material
which closes the lower opening of the tube when the liquid reaches a certain
height in the receptacle.
A counter B fixed on the receptacle is actuated by a star-wheel D which is acted
on by the lever L when moving downwards. A spring M bears against the star-
wheel and prevents its rotation except in the forwards direction by lever L. The
lever L acts on the star-wheel D through a pivotted spring catch or pawl F shown in
Figs. 2 and 3, which turns on its pivot sufficiently to clear the teeth of the star-
wheel in the upward movement of the lever.
The counter, Figs. 4, 5 and 6 is intended to indicate and check at any moment
the quantity of liquid consumed. It consists of a box or case of any kind enclosing
a wheel-work arrangement actuating a dial u for the units and a dial o for the
tens, the needle being fixed, it is evident that this counter is only given here by
way of example, any other system being capable of application to this apparatus.
In a state of inaction, the receptacle R being filled, the tube E which is con-
trolled by the valve e being in communication with a reservoir of liquid, and a
vessel of any kind placed under the outlet tubes controlled by the valve S, if
pressure be applied to the lever L, the rod T rises, closing the inlet E for the
liquid and opening the outlets as well as the air-intake s¹; the liquid in R
soon runs off, allowing the clack C to free the air-intake A, at the same time that
the star-wheel D of the counter has caused the dial u to move to the extent of
one hundredth of a revolution.
When, the liquid in R having run off, pressure is no longer applied to the
lever, which moves back again allowing the valves S and Si to close the air-
intakes and the outlet s; the valve sets free the opening of the tube E and the

page_text: liquid from the reservoir fills the receptacle R, at the same time that its level
reaches the clack C and closes the air-intake A.
By means of tubes or pipes, several of these apparatus of different capacity
can be connected with a cask or any other kind of reservoir. For instance, it is
possible to have one apparatus giving a litre, a second a half litre, a third three
decilitres, and so on, each apparatus being independent and having its own
counter.
The form and dimensions of this apparatus, the position of the counter, of
the lever and other parts, as well as the materials employed in its construction
may differ.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. An apparatus for drawing off and checking a given quantity of liquid, con-
sisting of a receptacle in which are three openings, one corresponding with the
inlet for the liquid to be measured, another with its outlet, and the third with
the external air, these three openings being capable of being opened or closed
by means of three valves fixed on a rod worked by an external lever so that, in
the position of rest, the air-intake and the outlet for the liquid are closed and
the inlet for the liquid open, whilst when pressure is put on the lever, the inlet
for the liquid is closed and the outlet for the same as well as the air-intake are
opened; a second air-intake being automatically closed when the liquid reaches
a certain given level in the receptacle, and each oscillation of the lever being
recorded by a counter or indicator which thus records and enables the number of
units of volume of liquid entering the receptacle, and running out of the same,
to be checked.
2. The improved apparatus for drawing off and checking a given quantity of
liquid substantially as described with reference to the drawings.
