COMPLETE SPECIFICATION.
An Improved Device for Automatically Regulating the Flow of
Liquids.
I, FRIEDRICH HÖLTJE of No. 7 p Katharinenstrasse, Brunswick in the Empire
of Germany, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be perforined, to be particularly described and ascer-
tained in and by the following statement :-
This invention has for its object an improved device for automatically regulating
the flow of liquids, by means of which in sugar works, breweries, chemical dye-
works and similar places, the supply and discharge of thick and thin liquids or
juices may be automatically regulated and the quantity of the same be simultaneously
set by the apparatus.
In the accompanying drawing the apparatus is shown in side elevation partly in
section.
An inflow pipe A is connected to the side of a vessel M by means of a flange so
that it supports the said vessel and the whole regulator. Au elbowed extension of
the pipe A within the vessel M is closed at its lower end by a tap or valve B.
This valve is connected with an oscillating beam G by means of levers C, D and
links E, F, said beam having at one end a float H and at the other an adjustable
counterweight J. The float H dips into a tank or cooling vessel K which is filled
with the juice or other liquid flowing in by a pipe L. The juice or liquid is
discharged from this tank through a dichage pipe N into a second vessel P.
The pipe N is closed at its elbowed end which enters the vessel by means of a
valve Q. The play of the valve Q is regulated by means of a second oscillating
beam mounted on the vessel P. The vessel P discharges into a vessel P¹ which
may be closed at the bottom by means of a valve Q'. This vessel P¹ is suspended
from one end of the beam V. The valve Q' may be exactly adjusted to a given
rate of discharge by moving an indicator R, attached to the valve spindle which
latter is supported by being screwed through a disc at the top of the vessel.
The point of the indicator R shows on a scale formed on a ring U the extent to
which the valve spindle has been screwed up or in other words the extent to which
the valve Q' has been opened by said screwing which may be ascertained very
exactly.
A suitable funnel is arranged under the vessel P' into which the latter may be
discharged.
The mode of action is as follows:
Assuming that the cooling vessel K is quite empty, it follows as a matter of
course that the float H lies deep down therein. Nevertheless by the action of the
oscillating beam G and of the links and levers F D E C, the valve B is opened
and in consequence of this the liquid from the pipe A flows into the vessel M and
from there through the pipe L into the vessel K. As soon as the liquid in the
vessel K has reached a certain height, and the float is also correspondingly high,
the valve B is closed by the action upon the above mentioned links and levers; in
other words, in consequence of the action of the float, only a certain quantity of
liquid can reach the vessel K. If the vessel K be emptied, the float I sinks and
liquid flows from the pipe L. The arrangement of the lower regulating apparatus
is similar. If the vessel Pl be quite empty, the beam V stands level. Upon the
vessel Prising, the valve Q opens and the liquid passes out of the vessel K into
the vessel P and from there to the vessel P Upon the vessel P sinking, the

page_text: valve Q is closed by the operation of the links and levers. As soon as the desired
measured quantity of liquid reaches the vessel P1, the Intter sinks and the valve Q
is completely closed by the tilting of the beam, whilst after opening the valve Q
and letting of the liquid, the vessel P being lighter rises and the valve Q opens
again so as to let a desired measured quantity of liquid again flow into the
vessel P.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An improved device for automatically regulating the flow of liquids, consisting
of a vessel (M) having an inflow pipe (A) provided with a valve (B) and a
float (1) connected with said valve by means of levers and an oscillating
benm (G) so as to control the flow of the juice or other liquid into a tank or
cooling pan (K) in which said float is placed, and a vessel P receiving the liquid
from said tank by means of a discharge pipe (N) and delivering the liquid into n
vessel (P) suspended from an oscillating beam (V) connected to a valve on the
aforesaid discharge pipe by means of levers and links and adapted by its weight to
control said valve (Q) substantially as hereinbefore described.
