Year: 1857

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street, in
the City of London, Patent Agent, for the Invention of "A METHOD OF
LUBRICATING AND PREVENTING THE HEATING OF AXLES, JOURNALS, AND BEARINGS
IN RAILWAY ENGINES AND CARRIAGES."-A communication from Schuler
Laurent.
Sealed the 21st July 1857, and dated the 26th January 1857.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his Petition,
on the 26th January 1857.
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 "A METHOD OF LUBRICATING AND PREVENTING THE HEATING OF AXLES,
JOURNALS, AND BEARINGS IN RAILWAY ENGINES AND CARRIAGES," communicated to
me by Schuler Laurent, a foreigner residing abroad); to be as follows:-
This Invention consists in applying, either continuously or at intervals, a
stream of cold water to the journals or axles and bearings in locomotive
engines and carriages, through a pipe leading from the feed pump of the
engine, tender, or other supply, whereby the journals and bearings are partially
lubricated, and prevented from becoming overheated.

page_text: The tube should be provided with a tap, having a handle within reach of the
engine driver or guard, so that by turning the tap he may project a stream of
water on the journal or journals, a portion of which water remaining in the
axle box, and being replaced by a fresh supply, surrounds the journal, lubricates
it, and keeps it cool.
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 23rd July 1857.
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 Twenty-sixth day of January, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth 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, my 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 "A METHOD OF LUBRICATING AND PREVENTING THE HEATING OF
AXLES, JOURNALS, AND BEARINGS IN RAILWAY ENGINES AND CARRIAGES," (a com-
munication from Schuler Laurent,) 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:
"

page_text: This Invention consists in applying, either continuously or at intervals, a
stream of cold water to the journals, axles, and bearings in locomotive engines
and carriages, through a pipe leading from the feed pump of the engine,
tender, or other supply, whereby the journals and bearings are partially
lubricated, and prevented from becoming overheated. The tube should be
provided with a tap, having a handle within reach of the engine driver or
guard, so that by turning the tap he may project a stream of water on the
journal or journals, a portion of which water remaining in the axle box, and
being replaced by a fresh supply, surrounds the journal, lubricates it, and keeps
it cool.
Figure 1 of the Drawings hereunto annexed represents a portion of the frame
of a locomotive to which this Invention is applied; Figure 2 represents a
separate longitudinal section of the portions of the lubricating pipes, in which
the valves are fitted on a larger scale than Figure 1. A is the body of the
feed pump of the boiler; B is the valve or plug, fixed upon the body of the
pump; C is a copper pipe, leading from the valve B to the axle F of the
wheel; y is the frame of the locomotive; is the platform of the same; D is
a rod which serves to transmit motion from a hand wheel or crank to the
valve B. In the case of the journal heating, the operator opens the valve B
by means of the rod D, and the water flows in a jet upon the journal until it
becomes sufficiently cool.
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 the application,
either continuously or at intervals, of a stream of cold water to the journals,
axles, and bearings in locomotive engines and carriages for the purpose of
cooling and lubricating the same, as herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand seal, this Twenty-third day of July, One thousand
eight hundred and fifty-seven.
R. A. BROUMAN. (L.S.)
