LETTERS PATENT to Robert Baillie, of Radnor House, Blackheath'
in the County of, Kent, Engineer, for the Invention of "AN IM-
PROVED METHOD OF HEATING LOCOMOTIVE OR OTHER ENGINE BOILERS, AND
THEREBY GENERATING STEAM WITHOUT FUEL CARRIED ON THE LOCOMOTIVE."
Sealed the 16th January, 1874, and dated the 1st November 1873.
‘PROVISIONAL SPECIFICATION left by the said Robert Baillie at the
Office of the Commissioners' of Patents, with his Petition, on the
1st November 1873.'
I, ROBERT BAILLIE, of Radnor House, Blackheath, in the County of
Kent, Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED METHOD OF HEATING LOCOMOTIVE OR OTHER ENGINE BOILERS, AND
THEREBY GENERATING STEAM WITHOUT FUEL CARRIED ON THE LOCOMOTIVE," to
be as follows :-
I
My Invention has for its object the application of heat to boilers for
the generation of steam therein in such a manner as to avoid the
ordinary emission of noxious gases therefrom through chimneys. For

page_text: this purpose the ordinary fire-box and furnace are dispensed with, also
the fire-tubes and chimney.
The boiler consists of a vessel for containing water, as usual closed at
each end, and furnished with chambers passing through the water, into
which chambers are inserted heaters composed of masses of previously
heated metal. By this arrangement the heat will be communicated from
the sides or walls of the chambers to the water surrounding them, and
will thereby evaporate the water, and cause steam to pass into a steam
chest in the upper part of the boiler as usual.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Baillie in the Great Seal Patent Office
on the 1st May 1874.
TO ALL TO WHOM THESE. PRESENTS SHALL COME, I, ROBERT
BAILLIE, of Radnor House, Blackheath, in the County of Kent,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria by Her
Letters Patent bearing date the First day of November, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Robert Baillie, Her special licence that
J, the said Robert Baillie, my executors, administrators, and assigns,
or such others as I, the said Robert Baillie, my executors, admini-
strators, 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 IMPROVED METHOD OF HEATING
LOCOMOTIVE OR OTHER ENGINE BOILERS, AND THEREBY GENERATING STEAM WITHOUT
FUEL CARRIED ON THE LOCOMOTIVE," upon the condition (amongst others)
that I, the said Robert Baillie, 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

page_text: Fig. 1 is a vertical section, representing a boiler of the construction
adapted for the purpose of the Invention; and Fig. 2 is a plan or hori-
zontal view of the same with the cover removed.
The boiler is circular and upright, being composed of two cylinders, B
and D, one within the other, the inside cylinder B containing the heater
A, and the space between the two cylinders forming the water and steam
chambers; E is the water space around and under the heater A, and F is '

the lifting out.
The size of heater shewn on the Drawing is eighteen inches in
diameter and twenty inches long. This is sufficient for keeping up
steam for about two hours, but the sizes of the heaters may be varied as
required.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that what I claim
as of my Invention is, the substitution for the ordinary modes of heating
locomotive and other engine boilers of heaters composed of iron pre-
viously heated in either a solid or a fluid state, for the purpose of gene-
rating steam without the emission of noxious gases as usual from the
combustion of coal and coke.
In witness whereof, I, the said Robert Baillie, have hereunto set
my hand and seal, the Twenty-ninth day of April, in the year of
our Lord One thousand eight hundred and seventy-four.
