I, JAMES MCFARLANE of Motherwell in the County of Lanark, North Britain,,
Bricklayer, do hereby declare the nature of the said invention for "IMPROVE-
MENTS IN GAS PRODUCERS OF THE SIEMENS' TYPE" to be as follows:-
This Invention which relates to Improvements in Gas Producers of the Siemens'
type has for its object to enable dross or small coal, as distinguished from nut or
round coal being utilized in such producers also to enable such gas producers to
produce a much larger quantity of gas in a given time.
The Invention consists as shewn on the accompanying drawings in constructing
the said Gas Producers with an enclosed hollow bottom a, underneath the bottom*
proper b, of which are passages c, connected with perforations d, in the said
bottom b, these passages c, also are connected with side openings e, round the
bottom b. Air is forced into the spaces c, beneath the bottom b, by a steam
blower for its equivalent and the air and steam escape by the perforations d, in
the bottom b, and through the openings e, at the sides thereof, up into the mass of³
dross or small coal resting on the said bottom b, of the gas producer...

Bricklayer, do hereby declare the nature of my invention for IMPROVEMENTS
IN GAS PRODUCERS OF THE SIEMENS' TYPE and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This Invention, which relates to Improvements in Gas Producers of the Siemens'
type, has for its object to enable dross or small coal, as distinguished from nut or
round coal, being utilized in such producers, also to enable such gas producers to
produce a much larger quantity of gas in a given time.
The Invention consists in constructing the said Gas producers with an enclosed
hollow bottom, underneath the bottom proper, of which are passages connected
with perforations, in the said bottom,-these passages also are connected with side
openings round the bottom. Air is forced into the spaces beneath the bottom by a
steam blower, or its equivalent and the air and steam escape' by the perforations in
the bottom and through the openings at the sides thereof up into the mass of dross
or small coal resting on the said bottom of the gas, producer."

In order that my Invention may be properly understood and readily carried into
effect, I will proceed to describe the drawings hereunto annexed:

In carrying out my present Improvements,,I construct the said Gas, Producers
with the enclosed hollow bottom a, underneath the, bottom proper b, of which are
passages c,, connected with the perforations d, which are formed through the (said
bottom b. These passages c, are further connected to the side openings,e, formed
around the bottom b. cAir, or a mixture of steam and air, is forced into the spaces
or passages c, beneath the bottom b, by a steam blower or its lequivalent. The,
steam blower is represented upon the annexed Drawings at f, and is of any of the
forms hitherto usually employed.-From the spaces or passages c, the air, or
mixture of steam and air, is forced up through the bottom b, by means of the
perforations d,, and around the said bottom b, through the side openings e.—In this
manner the air, or mixture of steam and air, is forced up into the mass of dross or
small coal resting on the bottom b, and being operated upon within the gas
producer.
ti:
It will be readily understood, by injecting air, or a mixture of air and steam,
into gas producers in the manner hereinbefore set forth with reference to the
annexed drawings, that dross or small coal in contradistinction to the large .or
lump coal hitherto burnt, is rendered capable of being operated upon, that is to
say, converted into gas, within such producers.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
-
First. In Gas producers of the Siemens type, the hollow bottom constructed
substantially as and for the purposes hereinbefore set forth with reference to the
annexed Drawings

page_text: Second. The perforations d, through the bottom b, of gas producers, substantially
as and for the purposes herein before set forth with reference to the annexed
Drawings,
Third. The openings e, arranged around the bottom b, of gas producers,
substantially as and for the purposes hereinbefore set forth with reference to the
annexed drawings.
