Sussex, Gentleman, for the Invention of "IMPROVEMENTS IN THE APPLI-
CATION OF CERTAIN FLUID AND OTHER MATTERS TO HEATING PURPOSES, AND
IN APPARATUS FOR THE SAME."
Sealed the 22nd December 1857, and dated the 15th October 1857.
PROVISIONAL SPECIFICATION left. by the said Richard Wright at the
Office of the Commissioners of Patents, with his Petition, on the
15th October 1857.
I, RICHARD WRIGHT, of Brighton, in the County of Sussex, Gentleman, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
APPLICATION OF CERTAIN FLUID AND OTHER MATTERS TO HEATING PURPOSES, AND IN
APPARATUS FOR THE SAME," to be as follows:-
My Invention relates, first, to the application of certain fluid and other
matters to heating purposes. In applying this Invention I enclose oil or fatty.
matter in tubes or channels of circulation carried to the point it is desired to
heat, and placed in communication with a peculiar construction of fire box"

page_text: herein-after described, by which the oil or other matter is heated. The tubes
or channels of circulation are formed, disposed, and arranged according to the
purpose for which they are applied. The fire box or furnace by which the oil
is heated is somewhat similar to the fire box of a locomotive engine, having a
double casing containing the fluid oil, and in addition thereto a series of tubes
which communicate between opposite sides of the double casing and form a
free passage for the oil. These tubes pass through the body of the fire in the
fire box, and are therefore in direct contact with the red-hot coke or other
fuel of the fire; they are placed at such distances apart as not to separate
the coke or coal so much as to interfere with the proper burning of the fire.
The oil in the coils or channels of circulation transmitting the heat to the
object or space to be heated is placed in communication with the fluid space
round the fire box (and consequently with the fire tubes before mentioned); in
such manner that a circulation of the oil is produced through such fluid space
or tubes passing away to the object to be heated, and returning after per-
forming its office to again take up more heat to be similarly transmitted, and
so on performing a continuous circulation. To facilitate the circulation of the
oil I sometimes apply a screw or other mechanical means.
By using oil or fatty matters as the medium of heating I am enabled to
transmit a high heat without generating any pressure in the coils or channels
of circulation, and moreover the tubes both of heating and transmission are
not subject to internal corrosion, but, on the contrary, are preserved by the
presence of the oil or fatty matter. I apply this system of heating to the
generation of steam, dessication, heating rooms, and to heating purposes
generally.
In its application to the generation of steam in locomotives I construct the
fire box of the engine as described, from which I carry a number of tubes
through the body of the boiler containing the water; the heated oil passes
from the double casing of the fire box at the higher level and returns by a
return channel at a lower level to the lower part of the fire box casing, and
thus keeps up a continuous circulation of the heated oil, and so transmits the
heat to generate steam from the water. In the upper part of the body of the
boiler I place a number of flue tubes in communication with the fire box and
smoke boxes in the usual manner. A small pressure may be generated in.
the oil chamber. and tubes if necessary by loading a safety valve, as may be
required. The heat of the fire should be so managed as not to allow this
valve to blow off and so waste the oil; a great pressure of steam may,
however, be attained without generating pressure in the oil chamber. at all.

page_text: In applying the circulation of this heated oil and fire box I sometimes
apply the circulation of the oil heated by circulating in the tubes passing
through the fire alone, and by which oil the heat is transmitted to a distant
purpose, while at the same time the external heating surface of the fire
may be applied to another heating purpose in presence of or in contact
therewith.
