page_text: 1 JOHN GARRETT TONGUE of the firm of Tongue & Birkbeck Patent Agents and
Engineers of 34 Southampton Buildings Chancery Lane London in the County of
Middlesex (a communication to me from abroad by Anders Andersen Pindstofte
and Rasmus Peder Andersen Pindstofte both of Copenhagen in the Kingdom of
Deninark Mechanical Engineers) do hereby declare the nature of this invention
and in what manner the same is to be porformed to be particularly described and
ascertained in and by the following statement :-
With the cocks or apparatus for tapping or drawing off beer and other liquids
in use up to the present time it has not been possible to regulate the discharge of the
beer or other liquid with the apparatus in accordance with the different degrees of
pressure as the float which acts as the regulator has invariably the same weight and
consequently cannot regulate the discharge in the same manner if the degree of
pressure that is to say the height from which the beer or other liquid is led to tho
apparatus be different.
The apparatus hereinafter described is for regulating the influx of the beer or
other liquid into the apparatus so that it is rendered constant at any height of
pressure.
The accompanying drawing shows a side view of the apparatus partly in section.
The beer or other liquid flows in through the pipe in the direction indicated
by the arrows and into the cylindrical sieve or strainer C from which it passes
into the reservoir or receptacle A whose upper edge is bevelled off to a knife edge.
A cover H arranged between the part G and the socket of the screw F closes the
cylinder A and its surrounding cylinder D at the top. The cover H can be raised
a little from the cylinder A and in this movement it is confined by the ring E which
is screwed to the cylinder D.
The beer or liquid which had entered into the cylinder A passes over the sharp
edge of it into the cylinder D from there to the pipe D¹ up into the wire gauze or
perforated cylinder E which as in the cylinder C acts as a sieve or strainer.
Through this sieve the beer or other liquid enters into the reservoir from which it is
drawn off.

page_text: In the reservoir the float K is placed which by means of the link K 1 is con-
nected with a lever whose other end is connected with the cover or valve H.
The lovor moves on the pin L which rests in the rod and screw M below so that
this turning point for the lever can be raised or lowered and thus adjusted by tho
nutN.

The float K' effects the regulating of the draught of the beer or other liquids as it
opens the valve H more or less according as there is littlo or much beer or liquid in
the apparatus. As however the float has one constant weight this regulating would
not suffice if the beer or other liquid which is led into the apparatus did not flow in
continually under the same pressure. This difficulty is here remedied by the fact that
the axis of the lever I can be adjusted and varied so that the apparatus maintains a
completely reliable rogulating and constant flowing to the apparatus with different
heights of pressure merely by regulating the axis of the lever I according to the
height of pressure.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved apparatus for drawing off beer and other liquids in which the
axis Is of the lever I which is connected both with flunt K and also with the valve II
can be placed at any height substantially as and for the purpose hereinbefore
described and represented in the drawing hereto annexed.
2. In apparatus for drawing off beer and other liquids a regulating valvo consisting
principally of the flont K the lever I the screw pin M and the nut N by which tho
result is obtained that the flowing of the beer or liquid to the apparatus may be
constantly regulated at whatever height the heer may be conducted to the apparains
substantially as and for the purposes hereinLefore described and represented in the
drawing annexed.
3. The improved arrangement and construction of apparatus for drawing off heer
and other liquids arranged to act substantially in the manner and for the purposes
hereinbefore described and represented in the drawing hereunto annexed.
