A NEW OR IMPROVED APPARATUS FOR REDUCING THE HEAT OF A BODY OF WATER
TO AN EQUAL TEMPERATURE THROUGHOUT, PRINCIPALLY FOR USE IN 'MASHING,' to
be as follows –
The object of this Invention is to reduce heated water to an equal temperature,
or thereabouts, throughout its entire volume, principally for use in 'mashing'
and other purposes in brewing; also for other uses where water of a uniform
temperature is desirable.
Hitherto it has been found difficult to heat large quantities of water to a
uniform temperature, unless it is boiled.
My improved apparatus is hereinafter called a 'regulator," meaning a regulator
of heat.
To attain the end proposed, viz. to heat a body of water equally throughout, to
the temperature required; it is first made hotter than is required; then, by mixing
cold water with it, by means of my improved apparatus, the water is reduced to
the required temperature; and so perfectly mixes the hot and cold water, that it
becomes of one uniform temperature throughout.
My improved regulator consists of an upright pipe, having a conical lower end;
an inlet is provided near the top, for the entry of hot water; and a little lower
down, on the opposite side, an inlet for the entrance of cold water. Inside this
upright pipe is inserted a ring or tube, partly perforated, having a sealed seating
at its top and bottom, extending below the cold water inlet; in the upper side of
this ring or tube; small holes are drilled, equally around it for the distribution of
cold water. Inside this ring or tube is placed a cylinder, with a sealed seating
resting on the top of the ring or tube, having its upper end open and the bottom
closed, leaving only sufficient space between the ring or tube and the cylinder, for
the requisite quantity of water to pass; the ring or tube and cylinder are held
down with a set-screw at the top.

page_text: The cylinder is also perforated, equally over its entire surface, with small holes.
On the lower end of this cylinder is fixed an inverted cone, around which is a
spiral web, something like a corkscrew, that fits in the conical end of the pipe.
The hot water is admitted into the top end of the cylinder, and flows thereout
through the small holes in its circumference, meeting the cold water, which is
distributed through the holes in the cylinder and, being in a very narrow space,
the two waters mingle together and, when the mixed water arrives at the spiral at
the bottom, its exit is checked, and it has to take the form of a screw, which causes
it to mix thoroughly well together, and is then fit for use.

Shoreditch, Engineer, do hereby declare the nature of my invention for "A NEW OR
IMPROVED APPARATUS FOR REDUCING THE HEAT OF A BODY OF WATER TO AN
EQUAL TEMPERATURE THROUGHOUT; PRINCIPALLY FOR USE IN MASHING" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of this invention is to reduce heated water to an equal temperature,
or thereabouts, throughout its entire volume; principally for use in 'mashing' and
other purposes in brewing; also for other uses where water of a uniform
temperature is desirable.
Hitherto it has been found difficult to heat large quantities of water to a
uniform temperature, unless it is boiled.
My improved apparatus is hereinafter called a 'regulator'; meaning a regulator
of heat.
In order that my said invention may be more fully understood, and be more
readily performed, I will explain the same with the aid of the accompanying
drawing which forms part of this specification, reference being made thereto by the
numerals and letters marked thereon, which reference applies to each figure of the
said drawing, where the same index numeral or letter appears.
Fig. 1 is an elevation; fig. 2 is a vertical section; and fig. 3 is a plan of my
improved regulator.
To attain the end proposed, viz., to heat a body of water equally throughout, to
the temperature required, it is first made hotter than is required; then, by mixing
cold water with it, by means of my improved regulator, the water is reduced to
the required temperature; and so perfectly mixes the hot and cold water, that it
becomes of one temperature throughout.
My improved regulator consists of an upright pipe a, having a conical lower
end al; an inlet b is provided, near the top, for the entry of hot water; and a
little lower down, on the opposite side, an inlet c is provided for the entrance of
cold water. Inside this upright pipe a is inserted a ring or tube d, partly
perforated, having a sealed seating at its top and bottom; in the upper side of this
ring or tube, small holes are drilled, equally, around it, for the distribution of cold
water. Inside the ring or tube d, is fitted a cylinder e with a sealed seating,
resting on the top of the ring or tube d, having its upper end open and the bottom
closed, leaving only sufficient space between the ring or tube d and the cylinder e,
for the requisite quantity of water to pass; the ring or tube d and cylinder e are
held down with a set-screw g at the top.
The cylinder e is also perforated with small holes, equally, over its entire surface.
On the lower end of this cylinder e is fixed an inverted cone h, around which is
a spiral web i, something like a corkscrew, as shown, that fits in the conical end of

page_text: the pipe a. The hot water is admitted into the top end of the cylinder e, by the
pipe b, as shown, and flows thereout through the small holes in the circumference
of the said cylinder e, meeting the cold water, which is distributed through the
holes in the cylinder e and, being in a very narrow space, the two waters mingle
together and, when the mixed water arrives at the spiral i at the bottom, its exit
is checked, and it takes the form of a screw, which causes it to mix thoroughly
well together; and it is then ready for use.
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
The apparatus for regulating the temperature of liquids equally throughout their
entire volume, substantially as herein described and shown in the drawing.
