Improvements in Apparatus for Heating, Cooling, or Attemperating
Water or Liquids
I, HENRY PRINCE, of 3 Victoria Street, London, SW, Mechanical Engineer,
do hereby declare the nature of this invention to be as follows
-
In carrying out my invention, I employ a device of similar con truction to an
injector, by means of which superheated steam may be forced through the cold
water inlet pipe in connection with baths or other appliances
The hot steam coming in contact with the cold water raises it to any desired
temperature
To regulate the temperature of the water, suitable steam and water valves
are used
When a steam or vapour bath is required, the inlet for water may be closed,
and the steam valve opened
When cold water is required, the steam valve is closed
The team valve and cold water inlet being both opened, a supply of water at
any temperature up to boiling point is obtained, and it may be temperised to any
degree by partial opening or closing of the valves
The cold water supply pipe terminates in a pipe or cylinder surrounding the
steam cone or nozzle
When used in connection with heating, cooling, or temperising apparatus in
breweries, distilleries, and other places, the employment of costly machinery
such as coils, perforated steam pipes, water heaters, Jacketed paus etc, may be
dispensed with
When my improved appliance is used in breweries or the like, double outlets for
the liquor may be provided, one being connected with coil or jacket, and one to
pan or vessel containing liquor
By closing the valve communicating with the vessel, and opening the inlet to
coil or jacket, the liquid may be heated, cooled, or temperised very rapidly
By closing the valve attached to coil or jacket, and opening that connected to
pan or vessel, the contents may be heated or cooled by contact with steam, or the
vessel washed out quickly without the necessity of manual labor
The supply of water through the injector or appliance above described, may be
obtained either by pressure or by suction, according as circumstances demand

I HENRY PRINCE of 3 Victoria Street, I oudon, SW Mechanical Engineer,
do hereby declare the nature of this invention and in what manner the same
18 to be performed, to be particularly described and ascertained in and by the
following statement
-
The object of my invention is to produce for use in attemperating water
and other liquids for any industrial or other purposes, a compact heater to be
operated by steam under pressure, and which can be easily fixed and manipulated,
and which will also work silently and instantly, as well as be simple in construction
and having nothing likely to go readily out of order The uses to which such in
apparatus may be applied are practically unlimited, and among them may be
mentioned the tempeiating of liquids for brewing, chemical, dyeing, laundry, and
domestic purposes, and for use as a combination draw off tap for supplying steam,
hot water, or cold to jacketed pans
Foi cooling purposes such as reducing the temperature of jacketed pans or of
vats heated by coils, the steam supply is simply turned off and the cold water only
allowed to flow into the jacket, or coil as the case may be
In carrying out my invention I provide cylindrical casting (hereinafter called
the body) of any convenient proportions as two and a half times its diameter
long I his casting is closed at its lower end, just above which I provide one or
more outlets for the temperated fluid The upper end of the body is furnished
with screw cap in which is inserted the inlet for the steam, the entrance of which
1s regulated by a screw-down valve or the lil e Into the upper end of the body
and at, o at about, a right angle to the axis thereof, I provide an inlet for the
water, the flow of which is regulated by a screw-down valve on the like Within
the body, and just below the bottom of the inlet for water, I provide an annular
ledge hiving screwed into it the luger end of a metallic cone, the lower end of
the cone being below the bottom of the outlet or outlets and reaching to within
a half an inch (more or less according to the size of the apparatus) of the bottom
of the body Immediately below the inlet for the steam and attached to, or
forming part of it, is a metal cone the larger cnd being uppermost and the lower
end being of such diameter as will allow it to enter the upper end of the bottom
cone already mentioned, and to leave between the two an annular opening of
about one sixteenth of an inch in width
I also arrange that the upper end of the
lower cone is about an eighth of an inch above the bottom end of the upper cone
The action of the apparatus is as follows
On turning on the water, the space around the upper cone will be filled with
water, and on tuining on the steam it will enter the upper cone and pass out at its
smaller end, and in its exit will draw the water through the annular space
surrounding the exit end of the upper cone and the inlet end of the bottom cone
and carry it with it to the bottom of the bottom cone out of which the mixed
steam and water will pass by the outlet or outlets provided for the purpose
thermometer or thermometers may be attached to the outlet or outlets so as to
indicate the temperature of the escaping water or liquid
A
One outlet or more than one can be used, and in the case of two or more they
may be permanently or temporarily connected with pipes leading to any part
where the use of steam, hot water or cold is required to heat or cool other
liquids
In order that my invention may be the more readily understood, I refer to the
sheet of drawings hereunto annexed, in which Fig 1 is a side view, Fig 2 a plan,

page_text: and Fig 3 a partly sectional view of one of my heaters

I do not confine myself to the prece shape, relative proportions or disposition
of parts as exemplified in the accompanying drawings, as any or all of the details
may be varied to suit particular conditions of work, without departing from the
spirit of the invention
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
-
1 A heater operated by steam under pressure, ror attemperating water and
other fluids for industrial and other purposes, and consisting sentially of a
containing cylinder or body having within it an upper cone in connection with the
steam generator and whose smaller end enters the larger end of a lower cone as so
to leave an annular space around the former the space in which is contained the
upper cone being connected with a supply of water, which on the passing of the
steam from the upper cone to the lower one, is drawn through the annular space
and forced into the lower part of the containing cylinder from whence it is drawn
off or distributed for any required purpose, the whole substantially as described
in the above Specification, and exemplified in the drawings
2 The combination of parts acting together and forming a combination draw off
tap, which will from its one or more outlets h (connected with steam and cold water
supplies) supply steam, hot-water, or cold, substantially as described in the above
Specification, and exemplified in the accompanying drawings
