Improvements in Apparatus for Altering and Adjusting the Outlet
Liquid Level in Tanks or other Vessels.
L
I, SAMUEL CUTLER of Providence Iron Works, Millwall, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction of apparatus whereby the outlet
liquid level in tanks or other vessels may be altered and adjusted with precision,
and are especially adapted for application to such vessels as are used in dissolving
solid matters.
The invention consists in placing a partition across the tank or vessel used so as to
divide it into two chambers each communicating with the other at the upper part by
reason of the partition not reaching quite to the top. There is also a communication
from one to the other near the bottom by one or more holes, so that the liquid portion
of the mixture may flow into the smaller or outlet chamber while the solid matter is
retained in the latter.
At a convenient height in the side of the smaller or outlet chamber is inserted a
pipe with a specially formed elbow capable of revolving or being partially revolved.
To one end of this elbow there is fitted the pipe for conveying the outflowing liquor
to its appropriate receptacle, and to the other end of the elbow is fixed a radiating
hollow arm.
Attached to the elbow there is also a worm wheel which is actuated by
a worm fixed to a spindle that passes through the tank and through the arm of a
bracket fastened to the top thereof, the part of the spindle projecting above the arm
being furnished with a suitable handle or hand wheel.-The spindle may have an
indicator which points to a scale fixed to the bracket.
It will be easily understood that on turning the handle the spindle and worm
will revolve and impart motion to the worm wheel, which being fixed to the elbow
will cause the radiating hollow arm to assume any desired angle to the vertical,

liquid contents of the tank will run, or may be drawn off therefore to a level
corresponding with the height of the top of the hollow arm, which may be altered or
adjusted at pleasure.

improvements in Apparatus for Altering and Adjusting the Outlet
Liquid. Level in Tanks or other Vessels.
I SAMUEL CUTLER of Providence Iron Works, Millwall, in the County of Middlesex,
Engineer 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 :-
This invention has for its object the construction of apparatus whereby the outlet
liquid level in tanks or other vessels may be altered and adjusted with precision and
are especially adapted for application to such vessels as are used in dissolving solid
matters.
In order that the invention may be easily understood drawings are attached thereto
of which the following is a description. Fig. 1 is a side sectional elevation of the
tank and the partition used when liquids and solids have to be divided but which
partition is not necessary when liquids of different specific gravities are to be dealt
with. Fig. 2 is a transverse sectional elevation of the same tank in which no partition
is shown.
In this invention I place when necessary a partition A across the tank or vessel B
used so as to divide it into two chambers C and D, each communicating with the
other at the upper part by reason of the partition not reaching quite to the top. There
is also a communication from one to the other near the bottom by one or more holes E,
so that the liquid portion of the mixture may flow into the smaller or outlet chamber D
while the solid matter is retained in the latter C.
At a convenient height in the side of the smaller or outlet chamber D is inserted a
pipe F with a specially formed elbow G capable of revolving or being partially
revolved. To one end of this elbow there is fitted the pipe F for conveying the
outflowing liquor to its appropriate receptacle, and to the other end of the elbow is
fixed a radiating hollow arm I. Attached to the elbow there is also a worm wheel J

and through the arm of a bracket M fastened to the top thereof, the part of the
spindle projecting above the arm being furnished with a suitable handle Ñ, or hand
wheel. The spindle may have an indicator which points to a scale fixed to the
bracket.
It will be easily understood that on turning the handle N, the spindle L and
worm K will revolve and impart motion to the worm wheel J, which being fixed to
the elbow G will cause the radiating hollow arm I to assume any desired angle to the
vertical, and consequently its top to be raised or depressed to the requisite level. The
liquid contents of the tank will run, or may be drawn off thereto to a level corre-
sponding with the height of the top of the hollow arm I which may be altered or
adjusted at pleasure.
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,
The combination of parts arranged so as to constitute apparatus to be used for the
purpose as herein set forth and as herein described and shown on the drawings.
