I WILLIAM SEDDON SUTHERLAND of Cherry Street Cannon Street Birmingham in
the County of Warwick, Engineer, do hereby declare the nature of the said invention
to be as follows:
The invention relates more especially to gas producers of the type for which I have
obtained British Letters Patent No. 1784 of the year 1874, and No. 80534 and
provisional protection No. 5915 of the year 1886.
The object is to provide appliances to be used with and form part of gas producers
so contrived and arranged as to facilitate the cleaning and clinkering of the said
producers and make them more economical and effective in working.
The first part of my invention consists in making or fitting producers with a grate
movable both circularly, that is about a vertical axis, and to and fro, in a straight line,
by means of a lever or equivalent device.
Under the second part I construct producers with a wind chest into which air is
forced by any suitable means beneath a movable grate and give motion to the said
grate by means of a spindle passing through the wind chest.
Under the third part I combine with producers under the first and second parts a
check valve to prevent back flow of gas into the air mains and passages.
Under the fourth part I provide apparatus to admit steam into producers constructed
under the first and third parts.
Under the fifth part, I construct a producer generally with a cylindrical body having
a bottom of refractory material perforated at the centre and fitted with a movable
grate and wind chest as above set forth. The wind chest is lined with brick, and
suitable cleaning and charging doors for the producer are provided.
.
Under the sixth part I combine two or more producers with one air supply and gas
take off pipes.
Under the seventh part I place on the air main a safety valve composed of an india
rubber disc, or of combined canvas and india rubber so constructed that if by any
back flow of gas into the air main an explosive mixture be formed in the main and an
explosion occur it will burst the disc of india rubber. No further damage is done,
and the valve is easily replaced.

page_text: I WILLIAM SEDDON SUTHERLAND of Cherry Street Cannon Street, Birmingham, in
the County of Warwick Engineer do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
The invention relates more especially to gas producers of the type for which I have
obtained British Letters Patent No. 1784 of the year 1874 and No. 8053** and
provisional protection No. 5915 of the year 1886.
The object is to provide appliances to be used with and form part of gas producers
so contrived and arranged as to facilitate the cleaning and clinkering of the said
producers and make them more economical and effective in working.
The first part of my invention consists in making or fitting producers with a grate
movable both circularly that is about a vertical axis and to and fro in a straight line
by means of a lever or equivalent device.
Under the second part I construct producers with a wind chest into which air is
forced by any suitable means beneath a movable grate and give motion to the said
grate by means of a spindle passing through the wind chest.
Under the third part I combine with producers under the first and second parts a
check valve to prevent back flow of gas into the air mains and passages.
Under the fourth part, I provide apparatus to admit steam into producers con-
structed under the first and third parts.
Under the fifth part, I construct a producer generally with a cylindrical body
having a bottom of refractory material, perforated at the center and fitted with a
movable grate and wind chest as above set forth. The wind chest is lined with brick
and suitable clearing and charging doors for the producer are provided.
Under the sixth part I combine two or more producers with one air supply pipe and
gas take off pipe.
Under the seventh part I place on the air main a safety valve composed of an india
rubber disc of combined canvas and india rubber so constructed that if by any back-
flow of gas into the airmain an explosive mixture be formed in the main and an
explosion occur it will burst the disc of indiarubber no further damage is done, and
the valve is easily replaced.
DESCRIPTION OF THE DRAWINGS.
Under my invention Figure 1., is a side view partly in section and partly in elevation
of a gas producer and Figure 2. a plan of three gas producers connected.
1. are the walls of producer, 2. carrying colums, 3. charging hopper and door,
4. gas outlet pipes, 5. cleaning out doors. These parts are of any usual or desired
construction. Under the first part of my invention the bottom of the producer is
made or fitted with a grate 6., fitting freely in the opening 7., and carried by a
spindle 8. The spindle 8. rests in a footstep 9. and has attached to it a lever 10. by
means of which the said grate has given to it both to and fro motion vertically and a

page_text: circular motion of rotation around the spindle 8. Under the second part, 11. is a
wind chest fitted beneath the grate and having the spindle 8. passing therethrough,
12. Air inlet way to wind chest. Under the third part the air inlet way 12. is fitted
with a check valve 13. to prevent the back flow of gas into the air main and passages.
The check valve may be of any well known or desired form and placed in any
convenient part of the airway. Under the fourth part a steam pipe and valve as shown
by the dotted lines 14., are provided when it is desired to admit steam into producers
having the improvements set forth under the first and third parts. Under the fifth
part a producer has a cylindrical body 1.-the center way 7., through a body of
refractory material,-a movable grate 6., wind chest 11.-lined with brick 15. or
equivalent refractory material.-clearing doors 5. and charging door 3. Under the
sixth part producers under my invention have one air supply pipe 16. and one gas
supply pipe 17.-Under the seventh part 18. is a disc of rubber or canvas rubber
secured over the open end of a straight lead in the air supply so that if a mixture of
gas and air enters the said airway and an explosion takes place the said disc will be
ruptured and no further damage done.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed-I declare that what I claim is :-
First. Making or fitting gas producers with a grate movable, substantially as set
forth.
Second. Constructing producers with a wind chest, beneath a movable grate,
substantially as set forth.
Third. The combination with producers under the first and second parts of my
invention of a check valve-substantially in the manner and for the purpose set forth.
Under the fourth part, providing producers under the first and third parts with
steam admission apparatus.
Under the fifth part, the combination of parts specified for the purpose set forth.
Under the sixth part, the combination of two or more producers with one air supply
pipe and one gas take off pipe, substantially as set forth.
Under the seventh part, the combination of a disc of indiarubber, or indiarubber
and canvas with the air main of a producer substantially in the manner and for the
purpose set forth.
