Improvements in Apparatus for Measuring Liquids.
I, JOHANNES TABEL, Merchant of Vellahn, Mecklenburg-Schwerin, in the
Empire of Germany, do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is an apparatus for measuring liquids. It
will serve specially for at any time measuring and controlling the quantity of beer
left in barrels, by enabling one to read off a scale the number of quarts still in the
barrels. To this end the apparatus has been contrived in different ways.

Fig. 1 is a longitudinal section of the apparatus without barrel.
Fig. 2 is a longitudinal section of the apparatus with barrel.
Fig. 3 is a side-view of the apparatus.
Fig. 4 is a cross-section of the apparatus.
Fig. 5 is a side-view of another apparatus with the scale.
C
The apparatus represented in Fig. 1-4 and Fig. 5 consists of a cylinder a, with
bottom, in which another cylinder o with plate is allowed to move up and down
by means of the guides r and rings 9 at the guide-rod p, fixed in the bottom of
cylinder a. The two cylinders a and o are hermetically closed against each other
by water poured into cylinder a. A barrel d is placed on plate c and a pipe s
mounts upwards through the water in cylinder a, which pipe, by means of tube e is
connected with a vessel having chambers, g, which communicate with each other
through aperture h. From chamber g there rises a glass-pipe i behind which a
scale has been placed which glides in battens kk. When about to be used, the
vessel f,g is filled with water and the full barrel placed on plate cof the cylinder o.
Through the weight of the barrel the air in the cylinders a and o is compressed
and the water in glass-pipe i before scale will rise. Scale is now set in
battens kk so as to place its zero mark at the highest level of the water.
If now
beer is tapped from the barrel, cylinder o will rise at the lesser weight through the
pressure of the water, sinking in pipe will indicate the quantity of beer drawn.
Instead of the cylinders one may also use a vessel a (Fig. 5) over which a
piece of rubber b is stretched; pipe i may also be connected with a vessel m with
rubber-piece n of the same size in order to counterbalance the atmospheric pressure
in vessel a.
The barrel d is placed on the plate c on the rubber-piece band the
arrangement is the same as described.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Measuring Liquids.
I JOHANNES TABEL of Vellahn Mecklenburg-Schwerin in the Empire of
Germany Manufacturer, 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 construct an apparatus for measuring liquids
[Price 8d1

page_text: which will serve specially for measuring and controlling the quantity of beer left
in casks or barrels by enabling a person to read off on a scale the number of quarts
still in the barrels.
To this end the apparatus is constructed as shewn by the drawings left with my
Provisional Specification in which
Fig. 1 represents a longitudinal section of the apparatus.
Fig. 2 represents a longitudinal section of the apparatus attached to a barrel
or cask.
Fig. 3 is a side view of the apparatus.
Fig. 4 is a cross section of the apparatus.
Fig. 5 is a side view of a modified form of apparatus with the scale.
The apparatus represented in Figs. 14 and Fig. 5 consists of a cylinder a closed
at one end in which another cylinder o with plate c is allowed to move up and down
being guided by means of the cross arms r rings 9 and the guide-rod p fixed in the
bottom of cylinder a.
The
The two cylinders a o are hermetically sealed by means of water poured into
cylinder a. A pipe s opening upwards through the water in cylinder a is connected
by means of tube e with a vessel having chambers fg which communicate with each
other through aperture h. From chamber g there rises a glass tube i behind which
is a scale sliding in guides k k. When the apparatus is to be used the vessel fg
is filled with water and the full barrel d placed on plate e of the cylinder o.
weight of the barrel compresses the air in the cylinders a and o and the water in
glass tube i in front of the scale will rise. Scale is then set in the guides k k so
as to place its zero-mark at the highest level of the water in the tube i. If now
beer is drawn from the barrel the cylinder o will rise owing to the reduction in
weight of the cask and its contents and the water in pipe i will fall and indicate
the quantity of beer drawn.
Instead of the cylinders I may also use a vessel a (Fig. 5) over which a piece of
rubber b is stretched, pipe i also may be connected with a vessel m with a piece of
rubber n of the same size in order to counter-balance the atmospheric pressure in
vessel a.
The barrel d is placed on the plate c on the rubber 6 and the operation
of the apparatus is the same as hereinbefore described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
"
1. An apparatus for measuring liquids consisting of the combination of the
cylinder e having a cylinder moving therein the two cylinders being hermetically
sealed by water pipe a tube e vesself and glass tubo in front of the scale
sliding in the guides all constructed and arranged as described and for the
purpo-e stated.
2. An apparatus for measuring liquids consisting of a vessel a coverul with a
piece of rubber band a vessel having a piece of rubber of the same size
connected with or attached to the glass tube i all constructed and arranged
substantially as described and for the purpose stated.
