PROVISIONAL SPECIFICATION.
Means for Collecting and Utilizing the Radiated Heat from
Locomotive Boilers.
I, HARRY VAUGHAN RUDSTON READ, of Broad Street Avenue, Blomfield
Street, in the City of London, Engineer, do hereby declare the nature of this
invention (a communication to me from John J. Impett, of Lima, Peru, Engineer,)
to be as follows:-
The invention as for its object means for collecting and utilizing the radiated
heat from boilers for the combustion of fuel in the fire boxes of locomotives.
For this purpose instead of covering the boiler of a locomotive with lagging or
non-conductive sheathing as heretofore, such lagging or sheathing is partly or
entirely dispensed with and in lieu thereof a metallic jacket is fixed around
or partially around the smoke box and the boiler body so as to form an air space
between such parts and the jacket; this jacket is open at the front of the smoke
box and the air space communicates with an air channel or enlarged space, which
communicates with an air space or chamber below the fire box.
By these means the radiated heat from the boiler and sınoke box is carried to
the fire partly by the air current caused by the passage of the locomotive through
the air, which latter impinges against the front end of the smoke box and is forced
into the circular cavity formed by the jacket around the smoke box, and partly
by the natural draft of the furnace and exhaust blast of engine, either separately
or combined, which draws it through the air space and air chambers to the
furnace.
Dated this 20th day of November 1895.

Means for Collecting and Utilizing the Radiated Heat from
Locomotive Boilers.
I, HARRY VAUGHAN RUDSTON READ, of Broad Street Avenue, Blomfield
Street, in the City of London, Engineer, do hereby declare the nature of this
invention, a communication to me from John J. Impett, of Lima, Peru, Engineer,
and in what manner the same is to be performned to be particularly described
and ascertained in and by the following statement :-
The invention has for its object means for collecting and utilizing the radiated
heat from boilers for the combustion of fuel in the fire boxes of locomotives. The
invention is illustrated in the accompanying drawings in which Fig. 1 is a
longitudinal section, Fig. 2 is an end view and Fig. 3 is a cross section of a
locomotive boiler fitted with the present improvements.
According to the present invention instead of covering the boiler of a loco-
motive with lagging or non-conductive sheathing as heretofore such lagging or
sheathing is partly or entirely dispensed with and in lieu thereof a metallic
D

page_text: jacket a is fixed around or partially around the smoke box b and the boiler body
so as to form an air space & between such parts and the jacket; this jacket a is
open at the front of the smoke box b and the air space d communicates with au
air channel or enlarged space e which communicates with an air space or chamber /
below the fire box g.
By these means the radiated heat from the boiler c and smoke box 6 is carried
to the fire partly by the air current caused by the passage of the locomotive
through the air which latter impinges against the front end of the smoke box b
and is forced into the circular cavity d formed by the jacket a around the s.noke
box 6 and partly by the natural draught of the furnace and exhaust blast of
engine, either separately or combined, which draws it through the air space d and
air chambers e. f to the furnace g.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In combination with a locomotive boiler, the device or method of collecting
and utilizing the radiated heat from the boiler, by means of a jacket, which
forms an air space around or partially around the boiler through which the heated
air is drawn by the natural draught of the fire, and the blast from the exhaust of
the engine separately or combined which draught is also assisted by the forced
air admitted at the front end of the air space by the velocity of the locomotive
through the air, substantially as herein set forth.
2. In combination with a locomotive boiler an air space d around or partially
around the boiler c in which the radiated heat is collected and conveyed to the
chamber substantially as set forth.
3. In combination with a locomotive boiler an air chamber which also forms a
part of the air space d into which the heated air is received collected and
conveyed to the fire box g substantially as and for the purpose set forth.
4. The means for collecting and utilizing the radiated heat from locomotive
boilers substantially as herein set forth.
