IMPROVEMENTS IN APPARATUS FOR BURNING GAS IN CARRIAGES, SHIPS, AND OTHER MOVING STRUCTURES
Year: 1860

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street; in
the City of London, Patent Agent, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR BURNING GAS IN CARRIAGES, SHIPS, AND OTHER MOVING
STRUCTURES." A communication from abroad by Pierre Hugon, of
Paris.
Sealed the 7th February 1861, and dated the 8th August 1860.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
8th August 1860.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR BURNING GAS IN CARRIAGES, SHIPS, AND OTHER
MOVING STRUCTURES," (communicated to me from abroad by Pierre Hugon, of
Paris,) to be as follows:-
There has been great difficulty in lighting carriages, ships, and other travel-
ling structures by gas, owing to the shocks and violent motions to which they
are subject, acting upon the regulator placed between the vessel containing the
store of gas and the burners, in such manner as frequently to shut off the
supply, and thus cause the light to be extinguished. Now, in order to guard.
against this serious defect the present Invention has been designed. It con-

page_text: sists in placing between the regulator and the burners a circular or other vessel
or holder of a capacity proportioned to the number of burners, whereby the
supply of the burners would be maintained should any sudden shock or jerk
cause the gas to be momentarily shut-off from the store to the regulator.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 8th February 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of August, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign;
did, for Herself, 'Her heirs and successors, give and grant 'unto me, the
said Richard Archibald Brooman, Her special licence-that I, the said Richard
Archibald Brooman, by executors, administrators, and assigns, or such others
as I, the said Richard Archibald Brooman, my executors administrators, and
assigns, should at any time, agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and. vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands and Isle of Man, an
Invention for "IMPROVEMENTS IN APPARATUS FOR BURNING GAS IN CARRIAGES,
SHIPS, AND OTHER MOVING STRUCTURES," (communicated to me from abroad by
Pierre Hugon, of Paris,) upon the condition (amongst others) that. I, the said
Richard Archibald Brooman, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof, reference being had to the Drawings hereunto
annexed, that is to say:-
There has been great' difficulty in lighting carriages, ships, and other travel-

page_text: ling structures by gas, owing to the shocks and violent motions to which they
are subject acting upon the regulator placed between the vessel containing the
store of gas and the burners, in such manner as frequently to shut off the
supply, and thus cause the light to be extinguished. Now, in order to-guard
against this serious defect the present Invention 'has been designed. It con
sists in placing between the regulator and the burners a circular or other
vessel or holder of a capacity proportioned to the number of burners, whereby
the supply to the burners would be maintained should any sudden shock
or jerk cause the gas to be momentarily shut off from the store. to the
regulator.
. I
Figure 1 of the accompanying Drawings shows in side elevation a railway
carriage furnished with a double gas holder, a' reservoir, and régulating distri-
butors for the gas-
-to the burners; Figure 2 is a view, partly in section, of the
upper and lower part of a railway carriage fitted with the apparatuses before
mentioned; Figure 3 is a cross section of a railway carriage, shewing the gas
apparatuses, and the manner of effecting a communication between them and
the lamp shewn also, but on a larger scale, at Fig. 4; Figure 5 is a transverse
section, and Figure 6 is a plan, on a larger scale, of the gas regulator. The
gas-issuing from the double gas holders A, A', is led by the pipes B into the
regulators C, a detailed description of which is hereafter given; from the regu-
lator C the gas is led through the pipe E into the supply reservoir F, and then
through the pipes G to the burner D in the lamp H. The regulators are made
in the following manner:-a is a metal case, best seen at Figures 5 and 6, con-
nected to a joint 6, in which there is a tap or valve c; this tap is threaded at d,
and allows in its descent flow of the gas from the passage e to the channel f.
The mouth of the channel f terminates in a guide h, which receives the valve i,
the inner end of which is bevelled and hermetically closes the channel f. The
valve i is jointed at k to a lever l, pivoted at m, and is governed by the ascent
and descent of the said lever. The up-and-down motion of this lever lis
maintained and regulated as follows:-n is an elastic diaphragm hermetically
closing the case a; it carries at its outer side a nut o, to which one end of the
lever Z is connected. When the gas which enters by the passages e and ƒ has.
filled the case a, the diaphragm in rising lifts the lever 7, which being pivoted
at m, pushes back the valve i, and closes the channel f. As the gas in the case
becomes exhausted the diaphragm n descends, and a fresh supply is admitted,
as before.
It is immaterial whether the reservoir be placed immediately after the regu-
lators or at any other point between them and the burner. Two tubes of large

page_text: diameter may be used in lieu of the regulators, which would then act as the
reservoir, but this alteration would make the apparatus more complicated.
Large gas holders, sufficient for a whole train, may be placed in or under the
guard's van, instead of placing gas holders under every carriage; but then it
would be necessary to make a connection between every carriage by india-
rubber pipes and suitable joints, and to fit a reservoir to each carriage, or to
connect one to every burner, in order to prevent the trepidation extinguishing
the lights.
... And having now described the nature of the said, Invention, and. in what
manner the same is to be performed, I declare that I claim as the improvements
in apparatus for burning gas in carriages, ships, and other moving structures,
the employment of a circular or other suitable vessel or holder for gas, placed
between the regulator or regulators, and the burner or burners, in order that
the supply to the burners may be maintained should any shock or jerk cause
the gas to be momentarily shut off from the gas holder to the regulator.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Eighth day of February, One
thousand eight hundred and sixty-one.
R. A. BROOMAN. (L.S.)
