Year: 1858

page_text: LETTERS PATENT to Edmund Burke, of 69; Upper Thames Street, in the
City of London, Iron Tube Manufacturer, for the Invention of "AN IM-
PROVEMENT IN APPLYING IRON TUBES TO LOCOMOTIVE AND OTHER TUBULAR
STEAM BOLLERS "A communication.
Sealed the 1st September 1858, and dated the 6th March 1858.
PROVISIONAL SPECIFICATION left by the said Edmund Burke at the
Office of the Commissioners of Patents, with his Petition, on the 6th
March 1858.
I, EDMUND BURKE, of 69, Upper Thames Street, in the City of London,
Iron Tube Manufacturer, do hereby declare the nature of the Invention.
for "AN IMPROVEMENT IN APPLYING IRON TUBES TO LOCOMOTIVE AND OTHER
TUBULAR STEAM BOILERS," to be as follows:-
This Invention has for its object an improvement in applying iron tubes to
locomotive and other tubular steam boilers. It is found in practice that in
using welded iron.tubes in locomotive and other tubular steam boilers the ends
of such iron tubes become very quickly injured..near the fire boxes and.
furnaces, and the improvement consists in fixing to the end of each of such tubes
or in lining each of such tubes at the end which comes to the fire box or
furnace with a few inches of tubing of brass, or of other alloy of copper with
zinc, or of copper, by which it is found that welded iron tubes are rendered;
more suitable for the flues of such steam boilers.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMUND
BURKE, of 69, Upper Thames Street, in the City of London, Iron Tube Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of March, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Edmund Burke, Her special licence that I, the said Edmund Burke, my
executors, administrators, and assigns, or such others as I, the said Edmund
Burke, 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 "AN IMPROVEMENT IN APPLYING
IRON TUBES TO LOCOMOTIVE AND OTHER TUBULAR STEAM BOILERS," a commu-
nication, upon the condition (amongst others) that I, the said Edmund Burke,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 Edmund Burke, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention, has for its object an improvement in applying iron tubes to
lecomotive and other tubular steam boilers. It is found in practice that in
using welded iron tubes in locomotive and other tubular steam boilers the ends
of such iron tubes become very quickly injured near the fire boxes and furnaces,
and the improvement consists in fixing to the end of each of such tubes or in
lining each of such tubes at the end which comes to the fire box or furnace with a
few inches of tubing of brass, or of other alloy of copper with zinc, or of
copper, by which it is found that welded iron tubes are rendered more suitable
for the flues of such steam boilers.

page_text: DESCRIPTION OF THE DRAWING.
Figure 1 shows a longitudinal section of a portion of an iron tube for the
flue of a steam boiler, having an end of brass, or of other alloy of copper, or of
copper, applied and fixed thereto. Figure 2 shows an external view of the
same, and Figure 3 shows the two parts separately.
a is one end of an iron tube, and b is a short length of brass or other alloy
of copper affixed thereto, in order that the end of a flue which is affixed to
the fire box may not be so quickly worn, as is the case when the end of an
iron tube is fixed directly to the fire box. The Drawing shows the arrange-
ment I prefer, but the end of the iron flue tube may be lined to a greater
extent than is shown. The parts a and b having been fitted together, they are
to be fixed by a suitable hard solder, as is well understood when combining
iron with brass or other alloy, or with copper.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that what I claim is, the appli-
cation to the ends of the iron flues of steam boilers of brass or other alloy of
copper, or of copper, as herein described.
In witness whereof, I, the said Edmund Burke, have hereunto set
my hand and seal, this Sixth day of September, in the year of our
Lord One thousand eight hundred and fifty-eight.
Witness,
JNO. ALCOCK.
