Sealed the 20th June 1873, and dated the 21st April 1873.
PROVISIONAL SPECIFICATION left by the said Claus Otto Bostelmann
at the Office of the Commissioners of Patents, with his Petition,
on the 21st April 1873.
I, CLAUS OTTO. BOSTELMANN, of Hamburg, at present residing at the
Royal Hotel, New Bridge Street, Blackfriars, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR MEASURING
AND RECORDING THE FLOW OF BEER AND OTHER LIQUIDS," to be as follows:-
This Invention has for its object improvements in apparatus for
measuring and controlling the sale of beer and other liquids.
The apparatus consists of a casing in which is contained a small
supply chamber, into which the beer or liquid descends from the cask,
and a ball cock or similar contrivance in the supply chamber causes it
to fill always to the same level. A measuring vessel is connected with

page_text: the supply chamber by a pipe on which is a three-way cock. The
measuring vessel may be of any desired capacity, and a pipe leads from
the top of it back to a gauge glass which is also connected with the
upper part of the supply chamber. Beneath the measuring vessel and
also in connection with the three-way cock is the pipe or spout which
delivers the measured quantities of the beer or other liquid. Upon the
plug of the three-way cock is a lever handle by which it can be turned
partly round so as to open communication either between the measuring
vessel and the supply chamber, or between the measuring vessel and the
outlet pipe or spout. There is also an index or counting apparatus
which is acted on by the lever, and registers the number of times the
handle is moved.
The action of the apparatus is as follows:-The supply chamber being
kept constantly charged, as already described, the three-way cock is
turned by means of its handle to the position in which it allows the
measuring vessel to fill. As soon as the liquid is seen in the gauge
glass, the handle of the cock is moved back, and so the three-way cock
is placed to the position in which the connection between the supply
chamber and the measuring vessel is closed, and the connection between
the measuring vessel and the delivery pipe or spout is open. The 1
measured quantity of liquid then escapes and flows into a receptacle
placed to receive it. As the handle is moved as above described, as it
passes the central position it gives motion to a rod which acts upon the
counter, and so causes the number shewn on the dial to be changed.
Each motion of the handle to draw off liquid causes the index to advance 2
one step. The return motion of the handle does not act upon the
index.
I make the measuring vessel by preference of copper, and when the
apparatus requires cleaning I cause water to boil in this vessel by

Letters Patent, bearing date the Twenty-first day of April, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Claus Otto Bostelmann, Her special
license that I, the said Claus Otto Bostelmann, my executors, adminis-
trators, and assigns, or such others as I, the said Claus Otto Bostelmann,
my executors, administrators, and assigns, should at any time agree with
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
excrcise, and vend, within the United Kingdom of Great Britain and
Ircland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN APPARATUS FOR MEASURING AND RECORDING THE FLOW OF BEER
AND OTHER LIQUIDS," upon the condition (amongst others) that I, the said
Claus Otto Bostelmann, my executors or administrators, by an in-
strument in writing under my, or their, or one of their hands and scals,
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calender
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Claus Otto Bostelmann, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say:―
This Invention has for its object improvements in apparatus for
measuring and recording the flow of beer and other liquids.
The apparatus consists of a casing in which is contained a small
supply chamber, into which the beer or liquid descends from the cask,
and a ball cock or similar contrivance in the supply chamber causes it to
fill always to the same level. A measuring vessel is connected with the
supply chamber by a pipe on which is a three-way cock. The measuring
vessel may be of any desired capacity, and a pipe leads from the top of
it back to a gauge glass which is also connected with the upper part of
the supply chamber. Beneath the measuring vessel and also in
connection with the three-way cock is the pipe or spout which delivers
the measured quantities of the beer or other liquid. Upon the plug of
the three-way cock is a lever handle by which it can be turned partly

page_text: cock are so arranged that measuring vessel 6 may be put in connection
either with the supply chamber a, or with the delivery spout g, and
when the plug of the cock is turned, the communication with the one is
closed before that with the other is opened. In one position of the cock
as already explained, the measuring vessel 6 fills until the liquid stands
in the gauge glass fat the same height as in the supply chamber a. In
the other position of the cock the measured quantity is discharged from
the vessel b, and the guage glass through the spout g; is an arm
fixed on the handle h; it gives a vertical motion to the rod k cach timo
the handle is moved. The rod k gives motion to a train of counting
wheels contained in the box l. The parts are so arranged that the first
wheel of the counting train is moved one tooth at cach upward motion
of the rod as the handle h passes its central position. The downward
motion of the rod is without effect upon the train of counting
wheels.
Tho
Sometimes in order to obtain greater rapidity of action, I make the
apparatus double-acting by providing two measuring vessels, so that one
my be filling whilst the other is discharging its contents.
measuring vessels are of equal capacity, and they are similarly fitted. A
four-way cock is employed in this arrangement; a side view of it is
shewn at Figure 3, and a front view partly in section at Figure 4. The
counter is operated upon and made to register at each motion of the
rod k, whether in an upward or downward direction.
What I claim is the construction of apparatus for measuring and
recording the flow of beer and other liquids, substantially in the manner
described.
In witness whereof, I, the said Claus Otto Bostelmann, have liore-
unto set my hand and seal, this Thirteenth day of October in
the year of our Lord One thousand eight hundred and seventy-
