IMPROVEMENTS IN AND APPLICABLE TO GAS PRODUCERS
Year: 1884

page_text: I, WILLIAM SEDDON SUTHERLAND of Richmond House Poplar Avenue, Sandon
Road, Birmingham in the county of Warwick, Engineer, do hereby declare the
nature of my said invention for IMPROVEMENTS IN AND APPLICABLE TO GAS
PRODUCERS to be as follows:-
:-
The invention relates to apparatus in which combustible gas mainly carbonic
oxide is generated by the passage of air through incandescent fuel and the objects
are to provide apparatus which shall admit of easy renewal of parts wearing out in
consequence of being exposed to the greatest heat, facilitate the feeding of fuel to
the producer and the cleaning and clinkering of the fire bars.
In carrying my invention into practice First. I make the producer in three parts
the middle one of which, constructed preferably of water-cooled brickwork is just
above the air supply and I carry the upper portion on screw or other elevating
appliances which rest on the lower portion. When the centre becomes worn the
upper portion is slightly raised by means of the elevating appliances and the worn
centre removed and replaced with new material, the upper portion is then lowered
to its original position.
Second. I make the top of the producer with rails or trams, fit the feed holes
with sliding doors and provide fuel holders or waggons with movable covers and
bottoms to run on the rails or trams. The said holders or waggons are adjusted
and arranged to push away the sliding doors and fit closely over the feed holes so
that fuel is admitted into the producer without allowing air to enter. To enable
the fuel holder or waggon to pass over feed holes when required, movable ramps are
used or the bodies of the holders may be capable of being raised and lowered.
Third. I make the fire grate of considerable length and carry it on slides, rollers
or wheels so that it may be moved by hand or power backwards and forwards to
expose any desired part out of the producer whilst another portion is under the
said producer and carries the fuel.
It is advisable to make the grate adjustable as regards height.

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 to apparatus in which combustible gas mainly carbonic

upper portion is slightly raised by means of the elevating appliances and the worn
centre removed and replaced with new material: the upper portion is then lowered
to its original position.
Second I make the top of the producer with rails or trams, fit the feed holes
with sliding door's and provide holders or wagons with movable covers and bottoms
to run on the rails or trams. The said holders or wagons are adjusted and arranged
to push away the sliding doors and fit closely over the feed holes so that fuel is
admitted into the producer without allowing air to enter. To enable the fuel
holder or wagon to pass over feed holes when required movable ramps are used or
the bodies of the holders may be capable of being raised or lowered.
Third. I make the fire grate of considerable length and carry it on slides rollers
or wheels so that it may be moved by hand or power backwards and forwards to
expose any desired part out of the producer whilst another portion is under the
said producer and carries the fuel.
It is advisable to make the grate adjustable as regards height.
DESCRIPTION OF THE DRAWINGS.
Fig 1 is a vertical section of a producer in which the first and second heads of
my invention are embodied and fig 2 an elevation at right angles of the fuel holder
or wagon and top of producer. The producer is made in three parts a b. c_The
middle part b where combustion takes place is surrounded by water spaces b¹ and
is just above the air supply pipes d. The upper portion a is carried on screw
elevators e on the pillars f¹ surrounding the lower portion c or the portion c might
be extended to form bearings for e. The upper portion can at any time be raised
by means of the screw appliances e and the middle portion removed for repairs or
to be replaced. Instead of raising the part a the part c may be lowered. The
level of the fuel in the producer is shown at a¹ and the combustion surface at c¹.
'
The top of the producer is made with rails g on which run the fuel holders or
wagons h. i feed hole for the producers fitted with a sliding door . The fuel

page_text: holders or wagons are made with bottoms k movable on the pivot L. The sliding
door j and movable bottom k are so arranged that each pushes away the other
when the wagon is run across the top of the producer so that the fuel may be
admitted into the producer without air being allowed to enter: for this purpose
the fuel holder or wagon is provided with a top or lid m. To allow of the fuel
holders or wagons being run over a producer without discharging their contents
they are provided with levers n pivotted at o so that the holders or containers may
be raised or lowered in their bearings p on the carrying axles q. When it is desired
to run a holder or wagon over a producer without discharging, the said holders or
wagons are raised by the lever until the door ; and movable bottom k are out of
contact. Instead of raising or lowering the holder or wagon movable ramps may
be used.
Fig 3 is a vertical section of part of a producer under my invention in which the
grate is carried on wheels 8 so that it can be moved backwards and forwards
along the rails t. The height of the grate above the rails can be adjusted by screw
wedge or like mechanism or by means of the open bearings u and pins v.
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. Producers in three parts connected together substantially as setforth.
Second. The combination in producers of a feed hole and movable cover with
wagon or fuel holder and movable bottom substantially as setforth.
Third. The combination with producers of a movable grate substantially as
setforth,
