ELLWOOD HORTON, of Priors Lee Hall, in the County of Salop, Ironmaster,
and ELISHA WYLDE, of Birmingham, in the County of Warwick, Engineer,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the. Fifteenth day of
April, One thousand eight hundred and fifty-two, in the fifteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Thomas Ellwood Horton and Elisha Wylde, our exors, admors, and
assigns, Her especial license, full power, sole privilege and authority, that we,
the said Thomas Ellwood Horton and Elisha Wylde, our exors, admors, and
assigns, or such others as we, the said Thomas Ellwood Horton and Elisha
Wylde, our exors, admors, or assigns, should at any time agree with, and no
others, from time to time and at all times during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend, within Eng-
land, Wales, and the Town of Berwick-upon-Tweed, and in the Islands of
Guernsey, Jersey, Alderney, Sark, and Man, and also in all Her said Majesty's
Colonies and Plantations abroad, our Invention of "IMPROVEMENTS. IN
APPARATUS FOR HEATING AND EVAPORATING;" in which said Letters Patent
is contained a proviso that we, the said Thomas Ellwood. Horton and Elisha
Wylde, or one of us, shall cause a particular description of the nature of
our said Invention, and in what manner the same is to be performed,
au instrument in writing under our hands and seals, or under the hand and
seal of one of us; to be enrolled in Her Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the

page_text: said in part recited Letters Patent, as in and by the same, reference, being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Thomas Ellwood Horton and Elisha Wylde, do hereby declare that the
nature of our said Invention, and the manner in which the same is to be
performed, are fully described and ascertained in and by the present
Specification thereof, reference being had to the Drawings hereunto annexed,
that is to say :-
Our Invention consists,―
First, in heating and evaporating by means of steam, or superheated steam,
generated in a separate chamber or compartment, and supplied through a pipe
or pipes traversing or entering the liquid or substance to be heated or
evaporated. By way of exemplification we have shewn our apparatus applied
to a Cornish boiler.
Figure 1 of the Drawings hereunto annexed represents a longitudinal
section of such a boiler with our improved apparatus for heating and evapora-
ting applied thereto; and Figure 2 and 3 are cross sections of the same.
A, A, is the shell of the boiler, which is divided internally into two compart-
ments or chambers B and C, by the division plate D. E, E, are two
longitudinal tubes in the compartments B, for containing the fire to be used
in heating the water in that compartment, and generating the steam to be
applied to evaporating the water in the chamber C, as herein-after explained.
F, F, are short connecting tubes placed at the back of the furnace tubes E, E,
which open into the flue G running beneath the chamber B. The flue G also
communicates, by means of the apertures a, a, with the two side flues H, H,
(Fig. 2,) which are continued along the length of the generating apparatus to
the division plate D, and then open into the flue I, running beneath the
compartment C, so that nearly the whole of the heat from the furnaces in
passing through the flues is imparted to the water in the two compartments.
K is a dome or steam chest rivetted to the top of the chamber B.
L is a
steam pipe which opens into the steam chest K, and is firmly held in that
position by stays b, b. The steam pipe L is continued down, and passes
through the division plate into the compartment C, where it opens into two
branch pipes L', L', in communication with the two longitudinal tubes M, M,
(Fig. 3,) running the whole length of the chamber C. The steam supplied
to these tubes M, M, evaporates the water in the boiler. Instead of two tubes,
a greater number may be employed. N is a second dome or steam chest,
surmounted by the valve box N'. O is the steam pipe which is connected to
the valve box N¹, and is used for conveying away the steam to the engine or

page_text: other purpose for which it is required. P is a hand wheel attached to a nut c,
upon the screwed end of the valve rod d, and is used for raising or lowering
the valve e to open or shut off the communication between the steam pipe O
and steam chest N. Q is a safety valve upon the top of the compartment C;
and R is a second safety valve upon the chamber B. S is a pipe in com-
munication with the two steam chests K and N, for conveying any super-
abundant steam, or any excess of steam over that necessary to evaporate the
water in the compartment C into the steam chest N. T is a valve for shutting
off the steam from the pipe L. V are cocks for drawing off the condensed
water in the longitudinal tubes M, M. This boiler is fed and provided witli
gauge cocks, safety indicator, &c., in the usual way. Or, instead of evaporating
the water in the compartment C by means of steam, as above described, hot
air tubes may be employed and connected to the furnaces in the tubes E, E,
in the manner usually adopted in hot air furnaces. These hot air tubes will
be made to communicate with the longitudinal tubes M, M, in the compart-
ment C, but in practice we should prefer the employment of steam in the
manner first herein-before described.
Second, our Invention consists in an apparatus for heating the tubes of hot
air furnaces by means of steam, or superheated steam, instead of by the direct
application of fire. This we propose to effect by enclosing the series of pipes
between the blast engine and the furnace in a steam jacket, so that the air in
its passage to the furnaces becomes sufficiently heated, and at the same time
the hot air pipes are not destroyed.
Third, our Invention consists in heating core stoves by means of the appa-
ratus for the reception of steam, or superheated steam represented in Figure 4.
A, A, is the core stove, the three sides and bottom of which are inclosed in a
steam jacket B, B; C is the inlet pipe for admitting the steam, and D the
exhaust pipe. Figure 5 represents a modification of the above apparatus for
heating core stoves, and consists in passing the steam through a series of pipes
B, B, instead of surrounding the stove by means of a jacket.
Fourth, our Invention consists in an apparatus for heating colors, varnishes,
oils, worts, confectionary, &c., a section of which is represented in Figure 6.
A, A, is an outer case, and B a pan for containing the material to be heated.
The pan
B has a rim formed round its upper edge, which is ground into a
corresponding rim on the outer case A; C is a steam pipe in communication
with a steam boiler or generator for conveying steam into the space between
the pan B and outer case A, to heat the material in the pan B; D is the
exhaust pipe for carrying off the waste steam and water of condensation. The
pan
B may be secured in its place in the case A by means of a bayonet joint,

page_text: as shewn in Figure 6, or by a flange and screw bolts, as represented in
Figure 7; E, E, are the handles for lifting out the pan B. One great
advantage possessed by this apparatus consists in the ready means afforded for
removing the pan and emptying it of its contents.
And having now described the nature of our said Invention, and the manner
in which the same is to be performed, we declare what we claim, as our
improvements in apparatus for heating and evaporating, are,-
First, the steam boiler herein-before represented and described, wherein the
water is heated and evaporated by means of steam, superheated steam, or
hot air generated in a vessel separate from the boiler, and conveyed thereto
by means of pipes or tubes, in the manner herein-before exemplified and
described.
Second, the apparatus for heating the tubes of hot air furnaces by means of
steam or superheated steam, in the manner herein-before described.
Third, the apparatus for heating core stoves by means of steam or super-
heated steam, in the manner herein-before exemplified and described under the
third head of our Specification.
And fourth, the apparatus for heating colors, varnishes, oils, worts,
confectionary, and other like purposes, as herein-before exemplified and
described.
In witness whereof, I, the said Elisha Wylde, have hereunto set my
hand and seal, this Fourteenth day of October, in the year of our
Lord One thousand eight hundred and fifty-two.
