Apparatus for Automatically Regulating the Level of Liquid in a
Vessel,
I, KILIAN GROSSWYLER, of No. 65, Sohlstrasse, Zurich, in the Republic of
Switzerland, Mechanic, 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 present invention relates to an apparatus to regulate automatically the
level of liquid of a supply vessel corresponding to the consumption of the liquid.
The preferred method of construction of this apparatus is shewn in vertical
section in the drawing filed with the Provisional Specification.
The vessel in which the liquid is to be continually maintained at about the
same level is shewn at a. This vessel is connected with a special vessel which
is divided into an upper compartment and a lower compartment 62 by a
partition 69. The partition 60 is penetrated by a tube c which projects sufficiently
far up into the upper compartment for the mouth of the tube or pipe c¹ to lie
above the level of the liquid, when the upper compartment is as full as it will
hold, whilst the lower end ² communicates with the atmosphere of the lower
compartment so that a constant equalization of the pressure of air over the
liquid in the compartments and takes place.
A tubular connecting pipe his fastened into the partition. The largest
part of this connecting pipe is placed in the compartment 2. Only the upper end of
the connecting pipe, which has the shape of a tubular projection of less diameter than
the rest of it, passes through the partition 6º, and projects into the upper com-
partment. A connection between the upper and lower compartments is thus
formed through which the liquid can flow from the former to the latter when the
lower opening 70 of the short pipe ¹ is free.
The part serves as guide for a cylindrical body k which is hollow throughout,
and goes nearly its entire length, and is fastened to a float 7, and the upper end
of which is in the form of a cone. This end serves as a valve for shutting the
lower aperture 7° of the short pipe h¹.
Between the vessel a and the lower compartment 62 a double communication

page_text: exists, one connected at the level of the liquid to be maintained constant
in the vessel a; whilst the other is placed higher up to connect the air
space in the vessel a, and that in the compartment 63 with one other. The con-
ducting pipe e serves to carry liquid from the compartment 62 into the vessel a,
whilst the pipe f equalizes the pressure between the vessel a and the com-
partment 62
The vessel is furnished with a valve g to let in air, so that when through
the flowing out of the liquid through the outlet cock i, the level of the liquid in
the vessel a lowers, and thereby the air pressure in vessel a is reduced, air can
be admitted through the valve 9 by the atmospheric surplus pressure.
If then, through the consumption of liquid, the level of the liquid in vessel a
sinks, a corresponding volume of air is admitted through the valve g into the
vessel; this air distributes itself by the pipes f and to all parts of the apparatus.
so that equal pressure over all is continually maintained. Consequently the level
of the liquid in the compartment 2 together with the float 1, sinks with the
consumption of liquid in the vessel a, whereby the lower mouth of the short
pipe becomes released; a corresponding quantity of liquid can therefore
flow from the compartment into the compartment 6, until the level of the
liquid in the latter again rises to the same height as before, at which instant the
mouth of the short pipe closes again. The operation continues in this manner
with the liquid constantly maintaining itself uniform in the vessel a and in
the compartment 2 until all the liquid in the upper, store compartment, is
finally consumed or has reached the upper aperture of the short pipe h¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. Apparatus for the automatic regulation of the level of liquid in a supply vessel
corresponding to the consumption, comprising an upper receptacle (6) containing the
store of liquid, and a lower receptacle (2), which two receptacles are separated from
one another by a partition such as (60) and in which in the lower chamber (62) (in_
which the same level as that in the supply vessel is to be maintained) there is a
float which is provided with a plug for an opening in the aforesaid partition (60)
for the exit of the liquid, and in which between the lower receptacle (2) and the
upper space of the top receptacle (61) an air-pipe is arranged so that the pipe
projects above the highest level of the liquid in the upper receptacle (b).
2. In apparatus of the kind set forth in Claim 1 the combination of the upper
receptacle (1), the lower receptacle (62), the partition (60), with means for
equalizing the pressure between the said spaces, and a float in the lower receptacle
with a guide (4) having a conical end (¹) enters in the lower opening (40) of
the partition (60) and leaves the opening more or less free according to the level
of the liquid in the lower receptacle.
3. In apparatus of the kind set forth in Claim 1 a pressure-equalizing pipe
such as (e), between the lower chamber and the top compartment of the upper
chamber with two pipes leading from the lower compartment to the vessel to
be supplied, of which the one pipe (c) serves for the flow of liquid, and connects
both vessels with each other, and the other (f) serves for the equalizing of the
pressure in the lower chamber (12) with that in the vessel to be supplied, sub-
stantially as and for the purpose described.
4. The improved apparatus for regulating the level of liquid in a vessel con-
structed and operating substantially as described and shewn in the drawing
filed with the Provisional Specification.
