PROVISIONAL SPECIFICATION.
Improved Means for Controlling the Proportional Flow of Liquids
and other Substances to be Mixed.
JOHN MOTTRAM SMALES, St. Pancras Schools, Leavesden, King's Langley,
Herts, Mechanical Engineer, do hereby declare the nature of this invention to
be as follows:-
It consists of an apparatus for regulating, automatically, the discharge, or flow,
of one or more liquids, in proportion to, and by the means of, the flow of another
liquid.
For this purpose, a cistern, or other suitably shaped receptacle for receiving a
liquid is used, having any desired number of outlets for the discharge of
the liquid.
The area of the outlets may be made adjustable, and so arranged, that the level
of the flowing liquid will vary in height, in proportion to the quantity entering the
receiving cistern; a float is employed, which rises and falls with the liquid in
the cistern, and is suitably connected with one or more valves or taps for regulating
the discharge or flow. of other liquids. The float may be placed in the receiving
cistern, which may be fitted with an open or perforated division, for the steadier
working of the float, or the said float may be made to operate in a separate cistern
or receptacle, in which case, the receiving and float cisterns or receptacles, are
connected by a pipe, or other suitable means, to maintain the same level of liquid
in each.
Upon the liquid commencing or ceasing to flow into the cistern or cisterns, the
float will rise or fall, thereby automatically opening or closing the valves or taps
that control the discharge or flow of other liquids.
In addition to the adjustable outlets a tap or valve may be fixed to the lower
part of the receiving cistern, whereby the height of the flowing liquid in the
apparatus may be more readily varied for the purpose of altering the relative
proportions of the liquids or gases, as may be desired.
When the said float is suitably attached to valves or taps for the purpose of
controlling steam, hot water, gases, or chemicals, it will do so in any desired
proportion to the flowing liquid, and one or more floats may be used in the same
or separate cisterns.
Where it is necessary to dispense with the float, the motion for governing the
valves or taps may be taken direct from the receiving cistern, one end of which is
placed upon a pivot, hinge, trunnion or bracket, the other end being suitably
balanced by springs, or weights, and free to rise and fall, according to the quantity,
or weight of the flowing liquid retained in the cistern, as determined by the area
of the adjustable outlets; to this, moving part of the cistern, suitable connections
are made to the valves or taps that regulate the flow of the liquids to be
controlled.

JOHN MOTTRAM SMALES St. Pancras Schools Leavesden Kings Langley
Herts, Mechanical 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 :→
It consists of an apparatus for regulating automatically the discharge or flow
of one or more liquids in proportion to, and by the means of the flow of, another
liquid. For this purpose a cistern, or other suitably shaped receptacle for
receiving a liquid is used, having any desired number of outlets for the discharge
of the liquid.
The area of the outlets may be made adjustable and so arranged that the
level of the flowing liquid will vary in height in proportion to the quantity enter-
ing the receiving cistern. A float is employed which rises and falls with the
liquid in the cistern and is suitably connected with one or more valves or taps for
regulating the discharge or flow of other liquids.
The float may be placed in the receiving cistern which may be fitted with an
open or perforated division for the steadier working of the float, or the said float
may be made to operate in a separate cistern or receptacle in which case the
receiving and float cisterns, or receptacles, are connected by a pipe or other
suitable means to maintain the same level of liquid in each.
Upon the liquid commencing or ceasing to flow into the cistern, or cisterns, the
float will rise or fall according to the quantity retained by the outlets, thereby
automatically opening or closing the valves, or taps, that control the discharge or
flow of other liquids.
In addition to the adjustable outlets, a tap or valve may be fixed at the lower
part of the receiving cistern, whereby the height of the flowing liquid in the
apparatus may be more readily varied, for the purpose of altering the relative
proportions of the liquids, or gases, as may be desired.
When the said float is suitably attached to valves, or taps, for the purpose of
controlling steam, hot water, gases, or chemicals, it will do so in any desired
proportion to the flowing liquid, and one or more floats may be used in the same or
separate cisterns.
Where it is necessary to dispense with the floats the motion for governing the
valves, or taps, may be taken direct from the receiving cistern; one end of which
is placed upon a pivot, hinge, trunnion, or bracket; the other end being suitably
balanced by springs, or weights, and free to rise and fall according to the quantity
or weight of the flowing liquid retained in the cistern, as determined by the area
of the adjustable outlets. To this moving part of the cistern suitable connections
are made to the valves, or taps, that regulate the flow of the liquids to be
controlled.
The outlets may be fitted on one or more sides of the cistern, and where the
cistern is circular, annular, or cone shaped, the outlets may be provided in any
suitable part.
DESCRIPTION OF DRAWINGS.
Fig. 1; is a plan. Fig. 2; front elevation with the splash guard removed.
Fig. 3; sectional elevation of the same apparatus. Fig. 4 shows an arrange-
ment whereby the float is dispensed with, and springs utilized to balance one
end of the cistern. The letters refer to the same parts in all figures.
A the cistern receiving the flowing liquid that passes in the direction of the
arrows through the adjustable hit and miss outlet valve D, the water rising or

page_text: falling, as the quantity entering varies, causes the float B also to rise and fall. To
the float is attached the rod C, which is connected by suitable means to a tap, or
valve, K; shown in Fig. 4; thus controlling the supply of other liquids. The
outlet valve is regulated by the hand wheels E, E, and screws E', E F, guide
and guide wheels for float. G splash guard, H division plate open at the lower
part. I tap for regulating and emptying cistern. In Fig. 4 the cistern is
supported by the hinge J, and the adjustable springs L. The pipe M conducts
the flowing liquid into the cistern, one end of which rises and falls according to
the weight of water retained by the outlets D, this imparts a controlling motion
to the tap K through the rod C, thus admitting one liquid in any desired
proportion to that flowing at M.
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 :-
passes
First. Utilizing the different levels produced by a flowing liquid, as
through a suitable receptacle provided with outlets, that retains the liquid at
various heights, corresponding to the area of the outlets; and to the quantity of
liquid flowing, which operates upon a float, that governs the supply of one, or
more other liquids, vapours, gases, or chemicals, in any desired proportion to the
flowing liquid.
Secondly. That a receptacle receiving a flowing liquid, suspended on a hinge at
one end, and by springs or weights at the other, provided with suitable outlets,
governs by its varying motion the supply of other liquids, vapours, gases, or
chemicals, according to the weight of liquid retained in the receptacle by
the outlets.
Thirdly. That by adjustable outlets in a receptacle, the relative proportions of
the liquids, vapours, gases, or chemicals are varied in any desired degree,
substantially in the manner, and for the purpose herein before described, and
represented in the drawings hereto annexed.
