PROVISIONAL SPECIFICATION left by the said George Gore at the Office

GEORGE GORE of Balsall Heath in the County of Worcester " IMPROVEMENTS
IN DOMESTIC AND LIKE STOVES AND FURNACES AND IN MEANS AND APPLIANCES TO
FACILITATE FEEDING THE FUEL THERETO OR THEREIN
"
The object of this Invention is to provide means by which the ordinary
bituminous coal can be burned in an open fire grate without producing smoke.
To do this effectually the fuel is supplied to the bottom of the fire where the
gradual process of cokeing takes place, and the gas given off during the process is
consumed in passing through the fire above.
The supply of fuel (which is sufficient for one days consumption) is contained in
a box or hopper constructed behind and above the back plate of the grate. The
back plate of the hopper is continued under the bottom and up to the front
and level with the bottom of the grate bars, forming a mouth to the basket in
which the fire is to burn,
In each of the two plates that form the sides of the hopper and near the mouth,
a shallow recess is cast of an irregular form, also a hole to receive the end of a
roller. A slot is formed through the centre of the roller and extends the whole
length. A metal plate is fitted to slide freely through the slot in the roller.
The slide plate and roller are of the same length and extend to the bottom of the
recesses cast in the side plates. The width of the slide plate is about one third
more than the diameter of the roller.
A wedge shaped piece of metal the length of the roller is either cast on, or
secured to the back plate of the grate so as nearly to touch the roller. The object

page_text: of this plate is to prevent any of the hot fuel being carried back into the hopper.
On this piece of metal rests the fire tile that forms the back of the fire and
prevents the fuel in the hopper from becoming too much heated.
An air chamber is formed at the back of the fire tile from which a supply of air is
admitted through slots cast in the wedge shaped piece of metal. The hopper is filled
with fuel through a door in the back plate of the grate or front part of the hopper.
The action of the feeder is as follows:-When the roller is made to revolve, the
projecting part of the slide plate forces forward the fuel into the bottom of the fire,
but when that end of the slide nearly reaches the fire it is forced back gradually
through the roller, and when it is close to the wedge shaped piece it disappears
within the diameter of the roller and thus passes the wedge piece without
projecting at all, at the same time the other end of the slide plate has been
forced out to project to its full extent thus being brought into position to force
forward the next charge of fuel.-The slide coming into contact with the inner
edges of the recesses causes the slide to move in or out as required.

IMPROVEMENTS IN
DOMESTIC AND LIKE STOVES AND FURNACES AND IN MEANS AND APPLIANCES.TO
FACILITATE FEEDING THE FUEL THERETO OR THEREIN
The object of this invention is to provide means by which ordinary house coal
or other like fuel can be burned in an open fire producing but little smoke to do
this the fuel is supplied to the bottom of the fire where the gradual process of
coking takes place and the gas given off during the process is consumed in passing
through the fire above.
By referring to the annexed drawing Figures 1. 2. 3 and 4 it will be seen that
the supply of fuel is furnished to and contained in a box or hopper A formed
behind the grate The back plate C of the hopper A is continued round the
bottom and up to the front till it is level with the bottom of the grate bars D
forming a mouth from the bottom of the hopper on which the fire is to burn.
In each of the two plates a a that form the sides of the box A a shallow recess E
is cast of an irregular form also a hole to receive the end of a drum or roller F
A slot is cast through the centre of the drum F and extends the whole length or
nearly so A metal plate G is fitted to slide freely through the slot in this drum or
roller. The slide plate extends to the bottom of the recesses cast in the side
plates and the width of the slide plate G is about one third more than the
diameter of the roller..
The wedge shaped piece of metal H the length of the roller is either cast on or
secured to the back plate of grate so as nearly to touch the roller at the point J.
The object of this plate is to prevent any of the hot fuel being carried back into
the hopper This wedge piece is hollow and has slots or nostrils open to the fire
through which air can be supplied this piece is connected to the hollów plates K
which form the end plates of the fire basket extending nearly to the ground line
and are open at the bottom; thus conveying the air direct to the wedge shaped
piece.
On the wedge piece rests the fire tile L which forms the back of the fire and
prevents the fuel in the hopper from becoming too much heated.
The box or hopper is supplied with fuel through the door M. N is the ordinary
flue door opening into chimney
.
The action of the feeder is as follows;-when the roller is made to revolve, the
projecting part of the slide plate forces forward the fuel into the bottom of the
fire, but, when that end of the slide plate nearly reaches the fire, it is forced back
gradually through the roller, and when it is close to the wedge shaped piece it
disappears within the diameter of the roller, and thus passes the wedge piece
without projecting at all; at the same time the other end of the slide plate has
been forced out to project to its full extent thus being brought into position to
force forward the next charge of fuel. The slide coming in contact with the inner
edges of the recesses causes the slide to move in or out as required.
The arrangement shown on drawing for giving motion to the feed roller is one
of many that can be used to effect the same object. The box wheel O is keyed
on the same spindle as the pinion wheel P this gives motion to the large wheel R
keyed on an axle of the drum or roller F It will be seen that when the lever S
is inserted in the box wheel, motion is given to the feed roller by pressing down
the lever.

page_text: I do not confine myself to any particular mechanical arrangement for giving
motion to the feed roller nor to any particular form of hopper or position in
which the hopper is placed and I may use more than one hopper if necessary for
supplying large boilers with fuel.
Having now described the nature of my said invention and in what manner the
same is to be performed I declare that I claim
First The roller and slide plate in conjunction with the recesses cast in or pro-
jections cast on the side plates of a hopper so as to cause the slide plate
to move in or out of the rollers as required for the purpose set forth
Secondly The wedge shaped piece, incline or stop, by means of which the hot fuel 1
is prevented from passing into the hopper.
Thirdly I claim The general arrangement of the various parts in combination as
shown in the annexed drawings
In witness whereof I the said George Gore have hereunto set my hand and
seal this fourteenth. day of September in the year of our Lord One thousand ]
