Year: 1881

page_text: LETTERS PATENT to William Shakspeare Welton, of No. 1, Winchester
House, Old Broad Street, in the City of London, for an Invention of
"IMPROVEMENTS IN FURNACES AND APPLIANCES FOR ECONOMIZING FUEL
AND CONSUMING SMOKE,"
PROVISIONAL SPECIFICATION left by the said William Shakspeare Welton
at the Office of the Commissioners of Patents on the 19th November 1881.
WILLIAM SHAKSPEARE WELTON, of No. 1, Winchester House, Old Broad Street,
in the City of London. "IMPROVEMENTS IN FURNACES AND APPLIANCES FOR
ECONOMIZING FUEL AND CONSUMING SMOKE"
This Invention has for its object improvements in furnaces and appliances for
economizing fuel and consuming smoke.
For these purposes the gaseous products of combustion and smoke are made to
impinge or pass through a screen or stratum of indestructable fibrous substance,
which substance becoming highly heated forms a focus of combustion and causes
the continual decomposition of the smoke and combustible constituents of the gases,.
at the same time the heat continually being stored up in the fibrous matter radiates
from the incandescent stratum or screen, and is as applicable for any useful purpose
as the heat obtained directly from fuel in the ordinary manner.
The fibrous material which I prefer to employ is asbestos, and I support it upon
a grating of bars similar to fire bars, so that the products of combustion from the
fuel may penetrate through and amongst the fibre. I provide also a valve by which
to admit such air as may be requisite to effect the combustion of the smoke whilst
amongst the fibrous refractory material.

WILLIAM SHAKSPEARE WELTON, of No. 1, Winchester House, Old Broad Street,
in the City of London. "IMPROVEMENTS IN FURNACES AND APPLIANCES FOR
ECONOMIZING FUEL AND CONSUMING SMOKE."
This Invention has for its object improvements in furnaces and appliances for
economizing fuel and consuming smoke.
For these purposes the gaseous products of combustion and smoke are made to
impinge or pass through a screen or stratum of indestructible fibrous substance,
which substance becoming highly heated forms a focus of combustion and causes
the continual decomposition of the smoke and combustible constituents of the
gases, at the same time the heat continually being stored up in the fibrous matter
radiates from the incandescent stratum or screen, and is as applicable for any
useful purpose as the heat obtained directly from fuel in the ordinary manner.
The fibrous material which I prefer to employ is asbestos, and I support it upon
a grating of bars similar to fire bars, so that the products of combustion from the
fuel may penetrato through and amongst the fibre.
I provide also a valve by which to admit such air as may be requisite to effect
the combustion of the smoke whilst amongst the fibrous refractory material.
In order that my said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto annexed.
No text detected.

asbestos which the products from the fire are made to traverse is supported.
Having thus described the nature of iny said Invention, and the manner of
performing the same, I would have it understood that I claim,-
My improvements in furnaces and appliances for economising fuel and con-
suming smoke by which the gaseous products and smoke are inade to pass through
a highly heated indestructible fibrous screen or stratum, substantially as described.
In witness whereof, I, the said William Shakspeare Welton, have hereunto set
my hand and seal, this Seventeenth day of May, in the year of our Lord
One thousand eight hundred and eighty two.
