Improvements in or Connected with Apparatus for Drawing off
Liquids for the Purpose of Indicating or Registering the
Amount Drawn off.
I, FRANCIS GEORGE TOLHURST of 42 Park Lane, Piccadilly in the County of
Middlesex, Club Manager do hereby declare the nature of this invention to be as
follows:-
The object of this Invention is to provide. means whereby the quantity of liquid
drawn off from containers thereof is indicated or recorded so that it can be readily
seen what quantity has been drawn off the indications or record being preferably
made so as to shew the sum which is due for the amount of liquid drawn off.
For this purpose I combine with the operating device of the pump or appliance by
which the liquid is drawn off an indicating or recording apparatus fixed in any desired
position either at the place where the liquid is drawn off or at a distance or both, so
that at each operation of the pump or drawing off appliance the indicator or recorder
is operated to an extent to shew the quantity drawn off or preferably the amount of
the payment due for such quantity so that as successive quantities are drawn off the
total quantity drawn off or the amount due for such total quantity is shewn on the
Indicator or recorder.
I make the pump or the like either single or double acting in the latter case each
drawing off stroke also supplying a corresponding quantity to that drawn off to a
receiving vessel which is situated between the cask or vessel in which the main supply
is contained the drawing off being made from the said receiver.
In order to give correct indications or records, there should be no waste and 'to
prevent this there may be a return pipe from the outlet pipe or spout back to the
reservoir.
If the Indicator or recorder be situated at a distance it may be worked by an
electric current.

Improvements in or Connected with Apparatus for Drawing off
Liquids for the Purpose of Indicating or Registering the
Amount Drawn off.
I FRANCIS GEORGE TOLHURST of 42 Park Lane Piccadilly in the County of
Middlesex Club Manager 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 :-
The object of this Invention is to provide means whereby the quantity of liquid 5
drawn off from containers thereof is indicated or recorded so that it can be
readily seen what quantity has been drawn off, the indications or record being
preferably made so as to show the sum which is due for the amount of liquid
drawn off.
For this purpose I combine with the operating device of the pump or appliance
by which the liquid is drawn off an indicating or recording apparatus fixed in any
desired position either at the place where the liquid is drawn off or at a distance,
or both, so that at each operation of the pump or drawing off appliance, the
indicator or recorder is operated to an extent to show the quantity drawn off or
preferably the amount of the payment due for such quantity, so that as successive
quantities are drawn off the total quantity drawn off or the amount due for such total
quantity is shown on the indicator or recorder.
I make the pump or the like either single or double acting, in the latter case each
drawing off stroke also supplying, a corresponding quantity to that drawn off, to a
receiving vessel which is situated between the cask or vessel in which the main supply
is contained, the drawing off being from the said receiver. In order to give correct
indications or records there should be no waste and to prevent this there is provided
a return pipe from the outlet pipe or spout back to the reservoir. If the indicator or
recorder be situated at a distance it may be worked by an electric current.
Figures 1 and 2 are views at right angles to each other illustrating my Invention as
applied to a single engine or pump for drawing off liquids and Figure 3 is a plan of
the same.
Figures 4 and 5 are views similar to Figures and 2 showing my Invention in
combination with two engines or pumps and a reservoir so arranged, that the reservoir
is charged with liquid at the same time and at the same rate as liquid is being drawn
off from the said reservoir.
Referring to Figures 1, 2 and 3, A represents a pump or engine similar in con-
struction to those employed in public houses and the like for drawing off malt liquors.
This pump is fixed on a reservoir B containing the liquor to be drawn off and
conveniently arranged beneath the bar or counter C, the suction pipe b of the said
pump extending inside the reservoir to within a short distance of the bottom thereof.
This reservoir which may be charged with liquor through the funnel c or otherwise is
provided with a gauge tube c² for indicating when the reservoir requires replenishing
with liquor.

page_text: The pump rod 2 is connected by the rod e to the "pull" or handle D which is
mounted loosely on a spindle d fitted to turn in a bracket fixed beneath the top of the
bar or counter C. On the spindle d is fixed a ratchet wheel g with which a spring
pawl g carried on the handle D engages, so that when the handle is pulled to draw
off the liquor it will cause the spindle to turn more or less according to the extent of
motion of the handle. is a spring detent to prevent the indicating wheel from
turning backwards when the handle is released or its motion reversed.
On the spindle d is also fixed a pinion in gear with a wheel ' attached to or
made in one with a disc i mounted on a spindle carried in bearings in the bracket f'.
The periphery of the disc i is divided into equal parts marked consecutively 0, 1, 2, 3,
and so on which marks or numbers, as the disc is rotated by pulling the handle D,
are successively brought opposite to and displayed through an opening in the top of
the bar or counter and thereby indicate the number of times the pump has been
operated, so that if the pump is arranged to discharge at each operation, a known
quantity of liquor, the value thereof, and the gross quantity or value of the liquor
which has been drawn off may be readily ascertained at any time by reference to the
number on the disc displayed through the opening in the bar or counter.
E is the delivery pipe of the pump A and F is an air pipe connected to the said
delivery pipe and communicating with the interior of the reservoir so that any liquid
remaining in the spout of the delivery_pipe E, after the handle D is released or
reversed, will return through the pipe F to the reservoir thereby preventing waste
and insuring a correct indication of the liquid delivered.
The delivery pipe may he provided with a stop cock as shown at E¹ to stop the
discharge of the liquid from the reservoir when required.
The distance to which the handle is to be pulled may be regulated so as to cause
the piston of the pump to make a half or a quarter stroke instead of a full stroke by
providing the stem of the handle with holes as at k for the reception of a pin or bolt
which when the handle is pulled will act as a stop by coming in contact with the
underside of the counter. In this case the indicator disc will be rotated to the
extent only of one half or one quarter, as the case may be, of a division on
the periphery of the said disc thereby rendering it necessary to make two or four
operations of the handle, as the case may be, to complete the motion of the disc to
the extent of one division so that the total quantity of liquor may be readily or
correctly ascertained.
Figures 4 and 5 illustrate an arrangement whereby the reservoir B is automatically
supplied with liquor at the same time and at the same rate as the liquid is being
drawn off from the said reservoir. A A² are two pumps the pump A being constructed
and arranged to operate in the manner described with reference to Figures 1, 2 and 3.
The handle D is made in two parts k k³ connected together by a ring k³, the part k
being connected by the rod e to the pump rod 62 and also to the mechanism for
working the indicator i (which may be of any suitable construction) whilst the part k²
is connected by the rod e² to the piston rod of the pump A².
The suction pipe e of the pump A2 communicates with the cask or barrel or other
vessel containing the liquid to be supplied to the reservoir B, the delivery pipe e of
the said pump entering the reservoir at the top and descending in the interior to the
bottom thereof.
When the two parts kk of the handle D are connected together, by pulling the
said handle to draw off liquid from the reservoir the pumps A and A² will be
simultaneously operated the latter drawing liquid from the cask or barrel into the
reservoir B equal in quantity and at the same rate, as the liquid is being drawn off
by the pump A thus the reservoir will be constantly supplied with liquid until the
vessel from which it is supplied is exhausted. When it is required to connect the
pump A2 to a fresh cask or barrel the two parts k k of the handle D are separated by
removing the ring and the part 2 only operated to work the pump A² until the
reservoir is sufficiently charged with liquid, the part of the handle remaining
inoperative and consequently the registering mechanism remaining unaffected. When
the reservoir is sufficiently charged the two parts kk² are again connected and the

page_text: pumps operated as herein before described. If the cask or vessel from which the
reservoir B is supplied be situated at a higher level than the reservoir I provide
the latter with a ball cock to govern the admission of liquid thereinto, the pump A²
of course being dispensed with. I do not restrict myself to the particular arrange-
ment of registering mechanism herein before described as various other arrangements
may be employed, such for example as those employed in gas meters for registering
the number of feet of gas consumed, or such as are employed in steam engines for
registering the revolutions of a crank.
The counting or registering apparatus may be situated at a distance from where
the pump is operated if desired and may be worked by electricity brought into action
by the operations of the pump or if desired duplicate registering apparatus may be
employed one being situated in proximity to the pump and the other being situated at
a distance therefrom.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what
I claim is :-
First. The combination with a pump or appliance for drawing off liquids of a
counting or registering apparatus operated by or from the drawing-off mechanism,
for indicating or recording at any desired place the quantity of liquid drawn off or
the amount of payment due for liquid drawn off substantially as hereinbefore
described.
Second. The combination with a pump or appliance for drawing off liquids from a
closed reservoir or vessel and a counting or registering apparatus for indicating and
recording the quantity of liquid drawn off, of an air pipe communicating with the
interior of the reservoir and the spout of the delivery pipe of the drawing off
appliance, substantially as and for the purpose hereinbefore described and illustrated
in Figures 1. 2. and 3 of the accompanying drawings.
Third. The combination with a pump or appliance for drawing off liquids from a
closed reservoir and a counting or registering apparatus for indicating or recording
the number of operations of the drawing off appliance, of an additional pump or
appliance operated simultaneously with and by the same handle by which the drawing
off appliance is operated so as to supply the reservoir with liquid to replace that
drawn off substantially as hereinbefore described with reference to Figures 4 and 5 of
the accompanying drawings.
