IMPROVE- MENTS IN MACHINERY TO BE WORKED BY THE APPLICATION OF THE EXPANSIVE FORCE OP AIR OR OTHER ELASTIC FLUIDS TO OBTAIN POWER
Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BRYAN
I'ANSON BROMWICH, of the Parish of Clifton-on-Teme, in the County of
Worcester, Gentleman, send greeting.
WHEREAS Her present Most Excellent Majesty Queen Victoria, by
Her Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventeenth day of June, in the second year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me; the said
Bryan l'Anson Bromwich, Her especial licence, full power, sole privilege and
authority, that I, the said Bryan l'Anson Bromwich, my exors, adiiors, and
assigns, or such others as I, the said Bryan l'Anson Bromwich, my exors,
admors, or assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVE-
MENTS IN MACHINERY TO BE WORKED BY THE APPLICATION OF THE EXPANSIVE FORCE
OP AIR OR OTHER ELASTIC FLUIDS TO OBTAIN POWER;" in which said Letters
Patent is contained a proviso, that I, the said Bryan l'Anson Bromwich, shall
cause a particular description of the nature of my said Invention, and in
what manner the same is to be performed, to be inrolled in Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in

page_text: 1, a fire-place, containing one or more hollow cylinders or chambers, in
which the air or other fluid is heated previous to being let out through the
tubes marked 3, under the pistons in the working cylinders; 2 shows the
cylinder or chamber above mentioned; 3, 3, two tubes with stop-cocks through
which the expanded air, vapour, or other elastic fluid passes into the working
cylinders under the pistons; 4, 4, two working cylinders with pistons, &c.;
5, the pedestal or standard to support the beam; 6, the beam with parallel
motion radius rods, &c.; 7, 7, two stop-cocks through which the rarified air or
other fluid is admitted into the cylinders to force up the pistons; 8, 8, two
stop-cocks through which the air, &c., escapes after it has forced the pistons up
to the required height; 9, one of the beams which is attached to the stop-
cocks 7 and 8; 10, a steel spring which pulls down the beam when liberated
from the catch 11 by the action of rod 12, and instantly opens the stop-cocks
to which it is attached; 11, the catch which keeps the beam down until
liberated by the motion of the rod 12; 12, 12, two rods, grooved at the upper
end, so as to allow the pin which is fixed in the beam to move either upwards
or downwards without acting upon the rods until the precise moment required;
13, 13, two pumps which forces the air, &c., into the receiving vessels
marked 14; 14, 14, two vessels into which the air is forced by the pumps, and
which has a communication (not seen in the Drawing) with the cylinders or
chambers contained in the fire-place, and which communication is regulated
by valves or stop-cocks.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I lay no claim to any of
the parts separately, and some of the parts may be varied, so long as the
principle of my Invention be retained; and I do declare that the novel features
of the Invention consist in combining in the same engine the means of con-
densing air into vessels and expanding the air for working in the engine or

page_text: ylinders, as above explained; and it will be evident that in place of atmo-
pheric air, I may use gas or gases in the same engine.
In witness whereof, I, the said Bryan I'Anson Bromwich, have hereunto
set my hand and seal, this Seventeenth day of December, in the year
of our Lord One thousand eight hundred and thirty-nine.
AND BE IT REMEMBERED, that on the Seventeenth day of December,
in the year of our Lord 1839, the aforesaid Bryan I'Anson Bromwich came
before our said Lady the Queen in Her Chancery, and acknowledged the
Specification aforesaid, and all and every thing therein contained and specified,
in form above written. And also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
Inrolled the Seventeenth day of December, in the year of our Lord One
thousand eight hundred and thirty-nine.
