PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Controlling and Registering
Quantities of Beer, Spirits, and other Liquids Discharged
Through Pumps or Engines."
1, ROBERT JEWELL, of 9 Victoria Road, Battersea Park, Surrey, Gentleman, do
hereby declare the nature of this invention to be as follows:-
In the Specification to my application No 12904 of 1889 I described a construction
of engine for drawing beer and other liquids, wherein the lover of the engine in being
moved for drawing the liquid, was made to actuate a slide or piston that, in moving,
made contacts on an electrical circuit and thereby actuated a counter or registering
apparatus for registering the quantity of liquid drawn at each stroke or fraction of å
stroke.
My present improvement has for its object to insure that such registrations shall
only be effected when by the motion of the lever, liquid is actually discharged from
the engine or pump, and it consists in combining with the engine or pump means
whereby, when only air or froth is being passed by the movement of the lever the
electrical circuit is maintained broken notwithstanding the contacts made by the
motion of the lever.
For this purpose I connect the pump of the engine with the discharge nozzle
through a receptacle so connected to a balance weight or spring that when the said
receptacle is empty, or only has air or froth passing through it, it is held by the
balance weight in a raised position in which it holds a contact or switch on the
electrical circuit in such a position as to keep open a break in the circuit, but when
by drawing liquid, the vessel becomes filled therewith, it descends by its greater
weight and thereby moves the contact or switch so as to close the break in the circuit.
The arrangement of the apparatus may be variously modified for carrying out this
mode of action. Thus according to one arrangement, I connect the closed vessel at
its lower end to the pipe leading from the pump by a flexible connection, and 1
connect the upper end thereof with the discharge nozzle by a similar flexible
connection. The vessel is mounted on one end of a balance beam the other end of
which is weighted and is connected to a tube that can slide up and down on a fixed
rod. This rod has an electrical contact connected with the electrical circuit and the
tube has another electrical contact piece, which, when the vessel is empty and in the
raised position, is held, by the balance lever in a lowered position out of contact with
the contact piece on the rod, but when the vessel is filled with liquid and consequently
descends, the tube is raised by the balance lever so as to bring the two contacts
together, and thus close the break in the circuit.

Improvements in Apparatus for Controlling and Registering
Quantites of Beer, Spirits, and other Liquids Discharged
Through Pumps or Engines.
I, ROBERT JEWELL of 9 Victoria Road, Battersea Park, Surrey, Gentleman, 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:
In the Specification to my application No. 12904 of 1889, I described a con-
struction of engines for drawing beer and other liquids, wherein the lever of the
engine in being moved for drawing the liquid was made to actuate a slide or piston

page_text: that in moving made contacts on an electrical circuit ard thereby actuated a counter
or registering apparatus for registering the quantity of liquid drawn at each stroke or
fraction of a stroke.
My present improvement has for its object to insure that such registrations shall
only be effected when by the motion of the lever, liquid is actually discharged from
the engine or pump, and it consists in combining with the engine or pump, means
whereby, when only air or froth is being passed by the movement of the lever, the
electrical circuit is maintained broken, notwithstanding the contacts made by the
motion of the lever.
For this purpose I connect the pump of the engine with the discharge nozzle
through a receptacle so connected to a balance weight or spring, that when the said
receptacle is empty or only has air or froth passing through it, it is held by the
balance weight in a raised position, in which it holds a contact or switch on the
electrical circuit in such a position as to keep open a break in the circuit, but when
by drawing liquid the vessel becomes filled therewith, it descends by its greater weight
and thereby moves the contact or switch so as to close the break in the circuit.
The arrangement of the apparatus may be variously modified for carrying out this
mode of action. The accompanying drawing shews one such arrangement by way of
example.
al
A is a closed vessel capable of sliding with an internal tube freely up and down on
a rod B carried by brackets C on a framing D, which vessel is connected by
branch A and flexible tube to the pipe leading from the pump, while a second
branch A² serves to connect it to the discharge nozzle of the pump or beer engine.
The vessel A is supported by one end of a balance beam E, pivotted at E¹ to the
framing D and bearing at its other end on an insulating disc F on a sleeve F of
conducting metal that can slide up and down on a guide rod G G¹ carried by
brackets H on framing D. The sleeve F has a second disc F of conducting metal
fixed to it, which supports weights I so proportioned as to overbalance the vessel A
when this is empty, in which case the parts are in the position shown in full lines, but
to be overbalanced by A when this is filled with liquid, in which case the parts are
brought into the position shewn in dotted lines.
The lower part G of the rod is formed of insulating material, and the upper part G¹
is of conducting material and carries at J a scrow terminal by which it is connected
to one part of the electrical circuit K of the apparatus L whereby the quantities of
liquid drawn by the pump or beer engine are registered on a counter M, as described
in my said prior specification.
A second screw terminal J¹ connects the other part of the circuit K to the sliding
sleeve F. From this arrangement it will be seen that so long as only air or froth is
being drawn through the pump by the pull of the engine, the vessel A being empty
the parts will remain in the position shewn in full lines, and the circuit K being then
broken, no registration of the movements of the pump lever or pull will be effected,
but as soon as liquid is passing through, the vessel A becoming filled, it will cause the
parts to assume the dotted position, in which the sleeve F will be put in conducting
contact with the rod G', and consequently, the circuit K being now closed the further
movements of the pump in discharging liquid will be registered on the counter M.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In combination with electrical registering apparatus whereby the quantities of
liquid discharged from a pump or beer engine are registered on a counter or
registering apparatus the use of a closed vessel capable of vertical motion and
communicating by flexible or jointed connections respectively with the discharge pipe
of the pump, and with the discharge nozzle, which vessel is so arranged in connection
with balance weights or springs and with electrical contacts of the circuit of the said
electrical registering apparatus, that when only air or froth is being drawn through
the pump the said vessel being empty will be situated in a raised position, in which it

page_text: will cause the contacts to break the electrical circuit, while when liquid is being drawn
by the pump, the vessel, becoming filled, will descend by gravity, and will thereby
cause the contacts to close the electrical circuit, substantially as described.
2. In apparatus for closing and breaking the circuit of an electrical registering
apparatus in connection with a pump or beer engine, the combination of a vertical
sliding vessel A connected by flexible connections with the discharge pipe of the
pump and with the discharge nozzle, a balance beam E a weighted sliding sleeve F on
a rod G G partly of insulating material and partly of conducting material and screw
terminals JJ situated respectively on the conducting rod G₁ and on the sliding
sleeve F, such terminals being connected to the circuit of the electric registering
mechanism, substantially as herein described.
