I, RICHARD JUKES, of Sheffield, in the County of York, do hereby
declare the nature of my said Invention for "CERTAIN IMPROVEMENTS IN
THE METHOD OF CONSUMING SMOKE, ECONOMIZING FUEL, AND PRODUCING LIGHT,
AND IN THE APPARATUS EMPLOYED THEREFOR," to be as follows :-
The Invention is designed for the purpose of economizing fuel in the
generation of steam or for other purpose, by a novel construction and
arrangement of apparatus that will enable the gases evolved from the
fuel during combustion to be entirely consumed, preventing thereby the
escape of smoke into the atmosphere.
In order that the Invention together with its application may be well
understood, I will proceed to describe the same as applied to steam
boilers or generators for the purposes of economizing fuel and the con-
sumption of smoke. The shell of the boiler or boilers may be of the
ordinary construction having the usual flue thoroughfares to the
chimnoy, that is, the draught after passing through the furnace is caused
to return by the sido flues and then dip and pass under the boiler to the

page_text: chimney, whereas according to the present Invention the unconsumed
gases are drawn by means of a fan into a thoroughfare running parallel
with the boiler through which they are forced into a gas or smoke receiver
conveniently placed in a transverse direction either above or below, an
arrangement of projecting fire-boxes placed at the entrance of each
furnace and closed in by the ordinary fire-door; each furnace through
tho medium of its fire-box is in direct communication with the gas or
smoke receiver above referred to, each thoroughfare of communication
being supplied with a damper in order that the admission of uncon-
sumed gas to the furnace may be regulated or shut off as required.
The action of the improved apparatus will be as follows:-When first
steam is being got up a small donkey engine or other equivalent may be
employed in order to cause circulation and create a draught, or if desired
the ordinary chimney may be employed for this purpose, but so soon as the
steam is up a damper is lowered so as to close all communication between
the furnace and the chimney, so that the unconsumed gases at this time
are drawn by the fan and passed by the side thoroughfare into the gas or
smoke receiver conveniently placed near to the entrance fire-box of the
furnace above the dead plates; thus the continued action of the fan
drawing air through the furnace bars or fire-doors causes the same, as it
becomes impregnated with unconsumed gases, to be forced into the gas
receiver, which is by the continued supply and pressure of the same
thereto forced out through the various thoroughfares leading to the
furnaco over which the unconsumed gases are again drawn by the fan,
and so pass and circulate through the furnace and the gas holder until
the whole of the combustable gases are entirely consumed. Dampers are
so arranged in the various thoroughfares of the flue or flues that the
passage and flow of gas is controlled, regulated, and directed as desired.
When it is desired to produce light a portion of the products of com-
bustion passed by the fan into the receiver is directed by another channel :
into a pipe immersed in hydrocarbon spirit or oil, contained in a closed
vessel from which it issues by another channel or pipe into a gas receiver,
when it is stored as a gas to be employed for illuminating purposes, such
as lighting works, factories, shops, or private dwellings.
