PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Controlling and Registering
Quantities 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 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 lever 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 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 or chamber in which is a float having a stem passing up through
the chamber and carrying at its upper end an insulated metal disc. To the top of the.
chamber are fixed two insulated supports each connected to part of the before
mentioned electrical circuit and carrying a contact spring projecting over the before
mentioned disc of the float. Thus when the chamber is empty or only has air or
froth passing through it, the float remains in the lowered position, and there being no
connection between the two contact springs of the circuit, this remains broken; but
as soon as the chamber becomes filled with beer or other liquid by the action of the
pump, the float rises, and its disc in coming in contact with both the contact springs,
effects the closing of the circuit, so that the movements of the pump lever can be
registered by the electric current in the manner described in my said former
application.

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
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 1 described a construction
of engine 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 that in moving
made contacts on an electrical circuit, and thereby actuated a counter or registering
077

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 the herein-
after described 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 or chamber in which is a float having a stem passing up through
the chamber and carrying at its upper end an insulated metal disc. To the top of
the chamber are fixed two insulated supports each connected to part of the before
mentioned electrical circuit and carrying a contact spring projecting over the before
mentioned disc of the float. Thus when the chamber is empty or only has air or
froth passing through it, the float remains in the lowered position, and there being no
connection between the two contact springs of the circuit, this remains broken; but
as soon as the chamber becomes filled with beer or other liquid by the action of the
pump, the float rises and its disc in coming in contact with both the contact springs,
effects the closing of the circuit, so that the movements of the pump lever can be
registered by the electric current in the manner described in my said former
application.
Figure 1 of the accompanying drawings shews a vertical section, and Figure 2 a
plan of a construction of apparatus for carrying out my above described Invention.
A is a vessel communicating at A' with the discharge pipe of the pump and at A²
with the discharge nozzle of the beer or other engine. Within this vessel is a
float B which, when the vessel is empty rests in the lowered position shewn upon a
perforated support C of the vessel A. This float can slide up and down freely with a
central tube B¹ on a guide rod C fixed to the support C. The upper end of the
tube B' passes through a hole in the top of the vessel, and carries at its end a disc D
of insulating material, on the upper face of which is fixed a plate of conducting
metal.
To the top of the vessel A are fixed two insulated standards E. E carrying contact
springs FF forming parts of the electric circuit G in which is included the electrical
contact apparatus H actuated by the lever or pull of the pump or beer engine, such
as that described in my aforesaid prior application, and also the counter or registering
mechanism I, on which the movements of the pull are registered.
From the above described arrangement it will be seen that so long as only air or
froth is being drawn through the pump, the vessel A being empty, the float will
remain in its lowered position, and the circuit G being broken between the
springs FF, 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 the
float will rise and its disc will consequently press against both the springs F F thereby
closing the circuit G and causing the further movements of the pump in discharging
_ liquid to be registered on the counter I.
"
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 vessel communicating respectively with the discharge
pipe of the pump, and with the discharge nozzle and containing a float operating in
combination with two contact springs forming part of the circuit of the electrical
apparatus in such a manner that when only air or froth is being drawn through the

page_text: pump, the said vessel being empty and the float in the lowered position, the circuit
will remain broken, but when liquid is being pumped, the vessel being filled and the
float raised, the latter will make contact with the said springs, so as to close the 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 vessel A
connected to the discharge pipe of the pump, and the discharge nozzle, a float B
within the vessel A, having a contact disc adapted to make contact with two contact
springs FF forming part of the circuit of the electrical apparatus, substantially as
described.
