CERTAIN IMPROVED MODES OF APPLYING PREPARED FUEL TO THE PURPOSES OF GENERATING STEAM AND EVAPORATING FLUIDS
Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
JOYCE, of Camberwell New Road, in the County of Surrey, Gardener, send
greeting.
WHEREAS Her present most Excellent. Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifth day of May, in the first year of Her reign and in the
year of our Lord One thousand eight hundred and thirty-eight, did, for Herself,
Her heirs and successors, give and grant unto me, the said Thomas Joyce,
Her especial license, full power, sole privilege and authority, that I, the said
Thomas Joyce, my executors, administrators, and assigns, and such others as
I, the said Thomas Joyce, my executors, administrators, 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 mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, the Town of Berwick upon
Tweed, and all Her Majesty's Colonies and Plantations abroad,. my Invention
of "CERTAIN IMPROVED MODES OF APPLYING PREPARED FUEL TO THE PURPOSES OF
GENERATING STEAM AND EVAPORATING FLUIDS;" in which said Letters Patent is
contained a proviso, obliging me, the said Thomas Joyce, by an instrument in
writing under my hand and seal, particularly to describe and ascertain the
nature of my said Invention, and the manner in which the same is to be per-
formed, and to cause the same to be inrolled in Her Majesty's High Court of

page_text: Chancery within six calendar months next and immediately after the date of
the 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, I, the said
Thomas Joyce, do hereby declare that the nature of my said Invention,. and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the following description thereof, reference being
had to the Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say):-
My improved mode of applying prepared fuel to the purposes of generating
steam and evaporating fluids applies to steam boilers or evaporating vessels,
and which are arranged and constructed with an external case, cylindrically
shaped, and placed in either a horizontal or vertical position, as situation or
circumstances may require. They have one, two, or more cylindrical, conical,
or other, shaped chambers enclosed within the external case or boiler, for the
purpose of supplying the furnace with fuel; and for the more economical
method or manner of generating steam, evaporating fluids, distilling spirits, &,
these cylinders or fuel chambers and furnaces are each furnished with a per-
forated bottom plate, as shewn in the accompanying Drawing, for the admission
of air to support combustion within, and also with a damper or regulator at the
upper part, in the chimney or exit pipe of the furnace, to regulate the degree
of combustion. The boilers or evaporating vessels are also furnished with pipes
to carry off the steam or vapour for the purpose required. The fuel to be used
in these chambers or furnaces may be wood, coke, coal, charcoal, or other fuel,
prepared, chopped, or broken into small pieces, so as to insure its falling down
the fuel chambers as the lower part of the fuel is consumed, thus supplying the
fire with fresh as long as any remains in the chamber or cylinder, and which
fuel may be saturated with alkali solution, and dried previous to use where cir-
cumstances require it; all of which will be better understood by reference to the
accompanying Drawings and to the letters and figures marked thereon (that
is to say)-Fig. 1 is a vertical section of a steam boiler or evaporating vessel,
with one of the simplest of my improved modes of applying fuel adapted thereto.
Fig. 2 is a horizontal section of the same, similar letters of reference being
marked upon corresponding parts in these and all the following Figures.
a, a, is the external casing of the boiler; b, b, the internal fuel chamber, fur-
nished with the cover c, and the exit pipe d, for the smoke or vapour arising
from the combustion of the fuel. This pipe has a regulator or damper e placed
in it, by which the degree of combustion can be determined. f is the aperture
for the admission of air to support combustion, and may be furnished with a
4+

page_text: hinged door if required; the fuel is supported by the perforated bottom plate g.
h is the exit pipe for the passage of the steam or vapour arising from the
ebullition of the fluid in the boiler or generator. When it is desired to light
the fire, this must be done first with a small portion of fuel, and then the
remainder applied, and the chamber b, filled, when combustion will go on
until the whole of the fuel is consumed. Fig. 3 is a vertical section of another
construction and arrangement of steam boiler or evaporating, vessel, with my
improved mode of applying fuel adapted thereto, and in this instance is fur-
nished with a caloric chamber for the better imparting the heat to the fluid.
a, a, is the boiler; b, the fuel chamber; c, the top or cover; d, the exit pipe
for the smoke and vapour, to which passes 3 or more pipes i, i, i, from the
caloric chamber k. The regulator or damper e is to be placed in the pipe das
before. ff, are the apertures at bottom. 9, the plate or fire bars. h, the
pipe to convey off the steam. Fig. 5 is another vertical section of a similar
arrangement and construction of boiler, in which the water or fluid is made to
pass under the fire; and the aperture f*, to admit air to support combustion, is
placed in the front, sides, or end of the boiler. The same letters of reference
being marked upon corresponding parts as in the former Figures, no further
description will be necessary. Fig. 6 is a vertical, and Fig. 7 a horizontal
section of another arrangement of boiler or generator, in which the hot air or
caloric chamber is formed as a circular pipe connected to the furnace part or
bottom of the fuel chamber by the pipes 7, 1, 1, which form flues to the cham-
ber k, the smoke or vapour passing off by the pipe d as before. Similar letters
of reference are marked in this as the foregoing Figures, therefore the former
description will suffice. Fig. 8 is another vertical section of an arrangement
of boiler or generator adapted for a green-house, conservatory, or forcing-house,
and in which the exit smoke and vapours arising from the combustion, as well
as the steam or vapour evaporated from the fluid, pass off' through one and the
same channel, the pipe d, which collects the smoke and vapour passing into
the tube h, which carries off the steam. This construction is applicable to any
purpose where it is desirable to heat the surrounding atmosphere. In this
instance the air to support combustion is admitted through the apertures in the
cone 0. Fig. 9 shews a simple arrangement of steam boiler with three fuel
chambers or cylinders placed therein, and constructed after the manner of
Fig. 1; and Fig. 10 is a similar section shewing the three fuel chambers or
furnaces adapted with the caloric chambers, as shewn in Figures 6 and 7; the
same letters of reference are also marked upon these as the former figures, and
therefore no further description will be required. m is the safety valve, and h
the steam pipe as before stated. In conclusion, I would remark that I have

page_text: not shewn these boilers set in any brickwork or standards, as they may be sup-
ported in any convenient way, as circumstances or situation may require, only
remarking that sufficient open space must be left for the admission of air to
support combustion and to remove the cinders or ashes.
In witness whereof, I, the said Thomas Joyce, have hereunto set my
hand and seal, this. Fifth day of November One thousand eight hun-
drod and thirty-eight
AND BE IT REMEMBERED, that on the Fifth day of November, in the
second year of the reign of Her Majesty Queen Victoria, the said Thomas

ledged the instrument aforesaid, and all and everything therein contained
and specified, in form above written. And also the instrument aforesaid was
