We, HERBERT NALDER, CHARLES WILLIAM SCOTT CRAWLEY and ALFRED
SOAMES, all of 16 Red Lion Street, Clerkenwell in the County of Middlesex
Electrical Engineers do hereby declare the nature of this invention to be as
follows:-
Our invention consists of a closed vessel whose capacity can be varied at will, such
as a cylinder with a piston working in it, or a bellows or other equivalent mechanical
device.
This vessel is in communication with a source of supply through a cock or valve,
and with the outlet through another cock or valve, or one 3 way cock or valve may
be used instead of the two.
A handle or other equivalent device, which in the first part of its movement
shuts the outlet cock and opens the inlet cock, and then by its further movement
increases the capacity of the vessel which consequently fills with liquid to any desired
amount, dependent on the amount the handle is moved.
The commencement of the return movement of the handle shuts the inlet cock and
then opens the outlet cock, and its further return movement decreases the capacity
of the vessel, and the liquid in the vessel flows or is forced out through the
outlet.
The method we sometimes employ to operate the cocks by the first portion of the
movement and return movement of the handle, is to put a segment on each cock, and
a rack actuated by the handle engaging with them.
The first movement of the handle then shuts the outlet cock and opens the inlet
cock, and the rack then trips past the segments.
Similarly on the return, the first movement of the handle shuts the inlet cock
and opens the outlet cock, and the rack then trips past the segments in like
manner.
When the 3 way cock is used-or the cocks are linked together-of course only
one segment is required.
We may of course use the same arrangement, working by friction instead of
with teeth.
We sometimes use a chain or perforated band -or similar device-instead of the
rack; and we also sometimes use a single lever or arm instead of the segment.
For the purpose of registering the amount of liquid drawn, we cause the handle
or other moving part, each time any liquid is drawn, to advance a counter propor-
tionately to the amount so drawn; this we may do by any well known mechanical
or electrical means.
We may also cause the movement of the handle-or other equivalent movement -
each time any liquid is drawn, to display an indication of such amount, or its
value.

page_text: An Apparatus for Drawing off Known Quantities of Liquid and
Registering the same.
We, HERBERT NALDER, CHARLES WILLIAM SCOTT CRAWLEY, and ALFRED
SOAMES, all of 16 Red Lion Street, Clerkenwell, in the County of Middlesex,
Electrical Engineers, 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 :-
Our invention consists of a closed vessel whose capacity can be varied at will,
such as a cylinder with a piston working in it, or a bellows or other equivalent
mechanical device.
This vessel is in communication with a source of supply through a cock or valve,
and with the outlet through another cock or valve, or one 3 way cock or valve
may be used instead of the two.
There is a handle or other equivalent device, which in the first part of its
movement shuts the outlet cock and opens the inlet cock, and then by its further
movement increases the capacity of the vessel which consequently fills with liquid
to any desired amount, dependent on the amount the handle is moved.
The commencement of the return movement of the handle shuts the inlet cock
and then opens the outlet cock, and its further return movement decreases the
capacity of the vessel, and the liquid in the vessel flows or is forced out through
the outlet.
The method we sometimes employ to operate the cocks by the first portion of the
movement and return movement of the handle, is to put a segment on each cock,
and a rack actuated by the handle engaging with them.
The first movement of the handle then shuts the outlet cock and opens the inlet
cock, and the rack then trips past the segments.
Similarly on the return the first movement of the handle shuts the inlet cock
and opens the outlet cock, and the rack then trips past the segments in like
manner.
Where the 3 way cock is used-or the cocks are linked together-of course only
one segment is required.
We may of course use the same arrangement, working by friction instead of with
teeth.
We sometimes use a chain or perforated band or similar device instead of the
rack; and we also sometimes use a single lever or arm instead of the segment.
For the purpose of registering the amount of liquid drawn, we cruse the handle
or other moving part, each time any liquid is drawn, to advance a counter propor-
tionately to the amount so drawn; this we may do by any well known mechanical
or electrical means.
We may also cause the movement of the handle or other equivalent movement --
each time any liquid is drawn to display an indication of such amount, or its
value.
In order that our said invention may be fully understood and readily carried into
effect we will proceed to describe the drawing annexed.
DESCRIPTION OF THE DRAWING.
The drawing shows a side elevation partly in section of apparatus in accordance

page_text: operating by friction upon an arm upon the plug of the cock. a is the measuring
cylinder and b is the three way cock. The cock is connected with e the supply
pipe by which the liquor flows or is drawn into the apparatus from the source of
supply, with d the spout or outlet and with the passage e by which the liquor enters
and leaves the cylinder a. f is the lever handle; it has its fulcrum at fand either
it or an arm fixed to it passes between two stops and g2 upon the rod of the
piston g; this piston is fitted into the cylinder a and suitably guided. is an endless
chain passing around pulleys h' ' it has studs upon it between which a blade "
connected with the handle passes, so that when the handle is moved it carries the
chain with it. i is the arm on the plug of the cock, it has two spring fingers which
embrace the chain h between them but not so tightly but that the chain, which is
smooth on the surface may still move on when the plug of the cock can turn no
further. Concentric with the axis of the upper pulley is another axis on which is a
ratchet wheel & the first of a train of counting wheels; there is also an arm and pawl!
and the pawl engages with and drives the ratchet wheel. The pawl is moved round
first in one direction and then in the other by pins upon the upper pulley ¹ and so
the counting wheels are intermittently driven. Provision may be made for a
certain amount of lost movement between the pulley and the pawl.
The action of the apparatus is easily understood; in the drawing it is shown in
the position of rest; when it is desired to draw a measured quantity of liquor the
handle is raised up to a stop (not shown) which may be placed higher or lower to
regulate the quantity drawn. In the first part of the movement of the handle whilst
it is passing from the stop g¹ to the stop g the piston does not move but the plug
of the cock is turned partly round so that liquor may pass from the inlet into the
measuring cylinder. Then in the latter part of the movement of the handle the
plug of the cock can move in further but the piston is raised so that the cylinder
may fill more or less. Then the handle is moved back to its original position and
so the plug of the cock is turned to connect the cylinder with the spout or outlet
and to close the inlet; this done the piston commences to descend and the liquid is
then expelled by the piston from the cylinder.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
An apparatus substantially as described which consists of a closed vessel, a cock
or cocks connecting this vessel with a source of supply and with a spout or outlet,
a handle moveable to and fro which during the earlier part of its movement in
either direction moves the cock or cocks and in the later part of its movement whilst
leaving the cock or cocks at rest alters the capacity of the closed vessel, and a
counter; the whole operating substantially as described to draw off measured
quantities of liquid and to register the quantities so drawn.
