PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Feeding Fuel to Gas Producers.
I, CHARLES JOHN COPELAND, Engineer, of Barrow in Furness, in the County
of Lancaster, do hereby declare the nature of this invention to be as follows:-
My invention relates to apparatus for feeding fuel to gas producers without
permitting escape of gas.
On the roof of the producer I mount on a vertical axis a cylinder which cause
This
to revolve slowly between a base plate below it and a cover plate above it.
cylinder has cavities or pockets arranged around its circumference, which, as the
cylinder revolves, come successively under an orifice in the cover plate, and over
an orifice through the base plate on the opposite side of the circular path in
which they move. Above the orifice in the cover plate is a hopper or bunker
containing fuel, a portion of which falls into each pocket as it presents itself
under it.
This fuel is carried round in the pocket until it comes over the orifice of the base
plate, through which the fuel drops into the producer below. The opening
of the hopper or bunker may be fitted with a slide to cut off supply when
required.
The slow revolution of the cylinder may be effected by worm gearing, worked
step by step by ratchet and pawl from a crank or eccentric or by other means.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Feeding Fuel to Gas Producers.
I, CHARLES JOHN COPELAND, Engineer, of Barrow in Furness, in the County
of Lancaster, 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 :-
My invention relates to apparatus for feeding fuel to gas producers without
permitting escape of gas.
On the roof of the producer I mount on a vertical axis a cylinder which I cause
to revolve slowly between a base plate below it and a cover plate above it. This
cylinder has cavities or pockets arranged around its circumference, which, as the
cylinder revolves, come successively under an orifice in the cover plate, and over
an orifice through the base plate on the opposite side of the circular path in
which they move. Above the orifice in the cover plate is a hopper or bunker
containing fuel, a portion of which falls into each pocket as it presents itself
under it.
This fuel is carried round in the pocket until it comes over the orifice of the
base plate, through which the fuel drops into the producer below. The opening
of the hopper or bunker may be fitted with a slide to cut off supply when
required.
The slow revolution of the cylinder may be effected by worm gearing, worked
step by step by ratchet and pawl from a crank or eccentric or by other means.
Fig. 1 of the accompanying drawings is a vertical section and Fig. 2 is a plan of
apparatus according to my invention for feeding a gas producer. The cylinder A,
provided with several pockets C revolves around a central pin B being driven slowly

page_text: by a worm gearing with a worm wheel D, the worm being on the shaft of a
ratchet wheel L worked by a pawl from an eccentric M on a shaft N which may
be driven by any convenient motor. A bracket F having through it a hole G
provided with a cover has bearings for the shaft of the worm E. On the opposite
side a bracket H supports the fuel hopper J, the discharge from which into the
successive pockets C as they come round, can be regulated by a slide K. Each of
these pockets receiving its charge from the hopper carries it round till the pocket
comes over the hole P through the base plate O when the charge of fuel drops into
the producer below.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Apparatus for feeding fuel to a gas producer, constructed and operating substan-
tially as described with reference to the accompanying drawings.
