COMPLETE SPECIFICATION.
Improved Apparatus for Checking the Withdrawal of Liquids from
Reservoirs containing the same.
I, JOHANNES BODEN, of 10 Pilluitzerstrasse, Dresden, in the Kingdom of
Saxony and German Empire, Merchant, 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:-
This invention relates to electrical apparatus for indicating the withdrawal of
liquids from a reservoir and the quantity withdrawn, the said apparatus being
specially designed for controlling the sale of beer. The apparatus can be arranged
to control the withdrawal of different sorts of beer or liquid.
The control apparatus has a paper band or strip which is moved forward by
clock mechanism on which band marks are made by a marker or style, or, when
several liquids are to be controlled, by a corresponding number of styles. The
markers or styles are operated by electro magnets, and another electro magnet
controls the working of the clock mechanism. Each style magnet is in circuit with
the clock inagnet so that, on completing the electric circuit which can be done by
operating the cock which regulates the flow of the liquid, the clock mechanism is
liberated, the corresponding style being at the same time brought into contact
with the paper band. According to the length of time the circuit is closed so
a longer or shorter mark will be made upon the band, the length of the said mark
indicating the quantity of liquid withdrawn.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing which illustrates an apparatus for checking
the quantity of liquid drawn from four taps.
Figures and 2 are a side view and plan respectively of the apparatus.
Figures 3 to 6 are sectional views drawn to an enlarged scale of details of the
apparatus, and
Figure 7 illustrates the arrangement of the electric circuits.
A is the clock mechanism of ordinary construction which receives its motion
from the spring barrel a and carries on a slowly rotating arbor the cylinder bon
which the paper band is wound as it is unwound from a cylinders. The
cylinder is attached to its axle, for instance, by a nut so that it can be easily
removed to allow of unwinding the paper band.
As the paper is unwound from the cylinders and wound upon the cylinder it
passes over a table e and under the styles (Figure 4).
:
Against the edge of a disc on the axle of a fly a spring brake presses,
which brake is fixed on the oscillating armature of the electro magnet F. By
means of this brake the movement of the clock mechanism and consequently the
rotation of the carrying roller is normally held stationary when, however, on
closing the electric circuit the armature is attracted by the electro magnet F the
brake is moved away from the disc, whereby the clock mechanism is free to
operate and move the paper band C.
"The speed of the motion can be regulated
by fixing the wings of the fly more or less tangentially or radially.
The electro magnets g of the marking mechanism G have their armatures g
composed of spring bars, each of which carries a tube y forming the style. These
tubes are filled with a thickly flowing color and are screwed into the armature
bars so that they can be adjusted. At the lower end of each tube is a small
opening through which, when at rest, no color will flow. The color tubes or styles
are arranged over different points in the width of the band so that the marks
produced by them lie side by side. For better distinction different colors can be

different sets of marks.
༡
On closing the circuit of one of the magnets its armature will be attracted and
its color tube or style pressed down to the paper band, whereby the colour in the
tube will mark the band, the length of the mark being greater or less according to
the time the circuit is maintained closed.
The arrangement for closing the circuits must naturally he such that on drawing
a certain kind of beer only the corresponding style shall produce a mark. For this
purpose a conducting wire leads from the battery 11, Figure 7, to one part of each of
the contacts and from the other part of each contact a special conducting wire
leads to the coils of the corresponding magnety which is also connected with a
bar K, which bar is connected with the battery through the coils of the electro

arrangement on closing one of the contacts J, which are marked with successive
numerals, only the electro magnet which is marked with the same numeral and
the magnet are energized.
To produce the closing of the circuits I could arrange the contacts in connection
with the taps themselves. Such an arrangement would however be too easily
ccessible. have therefore given the preference to a contact arrangement
operated by the Bowing beer. Tato each conduit or pipe i extends the flattened
end of a lever which passes through an india rubber disc. This disc which
covers a lateral opening in the pipe serves as a pivot to the lever i and also by
renson of its elasticity holds the lever in a certain position (Figure 5) so long as
the liquid is at rest in the pipe. When, however, on opening the draw off cock
the liquid flows in the pipe in the direction of the arrow (Figure 5) the lever is
deflected whereby the aid lever makes contact with a fixed contact and closes
the circuit.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed declare that what 1
claim is :-
1. In apparatus for checking the drawing off of liquid from a reservoir the
arrangement of a paper band moved by clock mechanism and one or more marking
devices operated or each operated by an electro magnet, in circuit with an electro
magnet which controls the clock mechanism, the said magnets being so arranged
that, when the circuit is closed by drawing off the liquid, the clock mechanism is
liberated and the paper band is put in motion and at the same time the electro
magnet operating the marking device draws the latter into contact with the paper
band in order to produce a mark thereon, substantially as described.
2. In apparatus of the kind described in the preceding claiming clause for
checking the withdrawal of liquid from a reservoir, a contact device having a
contact lever which extends into the draw of pipe and is moved by the current of
liquid flowing through the said pipe to make contact with the fixed part of the
contact device, substantially as described.
3. The manufacture and use of the improved apparatus for checking the with
drawal of liquid from a reservoir substantially as hereinbefore described and
illustrated in the accompanying drawing.
