PROVISIONAL SPECIFICATION.
Improvements in Smoke Consuming and Bottom Feeding Apparatus
for Furnaces, Ranges, Stoves, and other like Apparatus.
JAMES HINTON Mechanic ANNIE AMELIA HINTON no occupation 3 Oxford
Terrace Wellesley Road Gunnersbury in the County of Middlesex do hereby
declare the nature of this invention to be as follows:-
In an invention of this description I use a tube or chamber underneath the grate
by this means the fuel is conveyed into the furnace or grate, stove or other
apparatus after the fire has been kindled by this means nearly all the smoke is
consumed.
2. In the tube or chamber I use a series of flaps or trays the coal or fuel is
placed into the spaces and by means of a lever or a ratchet and pawl or cogs or
other like suitable mechanism I raise or force vertically or along at any suitable
angle the said fuel into the furnace.
3. In a furnace it may be arranged so that the fuel is delivered into the centre of
the grate or each side alternately.
4. And by use of bars of a desired angle or segments of a circle the grate surface
would be increased and so improve the draft that is somewhat decreased by the
slow combustion caused by bottom feeding.
5. In stoves or other like apparatus of that kind I use a tube or chamber of the
same size as the inner area of the said apparatus when it is used as a smoke
consuming and slow combustion apparatus.
6. In apparatus that is not intended for such slow combustion I used a tube or
chamber less than the inner area of the said apparatus and by using bars of a
desired angle or segments of a circle and by that means the combustion is not
so slow.

COMPLETE SPECIFICATION.
Improvements in Smoke Consuming and Bottom Feeding Apparatus
for Furnaces, Ranges, Stoves, and other like Apparatus.
I, JAMES HINTON and ANNIE AMELIA HINTON of 3 Oxford Terrace, Wellesley
Road, Gunnersbury London, Mechanic, do hereby declare the nature of this inven-
tion 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 improvements in stoves, ranges furnaces and the like and
has for its object to provide new or improved means for feeding fuel to the fire
grates of these apparatus in such a manner that the smoke may be consumed and to
effect corresponding improvements in the construction of such fire grates.
In the accompanying drawings
Fig. 1 is a front elevation of a kitchen range embodying my improvements.
Figs. 2, 3, and 4 are respectively a plan, a vertical cross section, and a central
longitudinal section of the fire grate drawn at an enlarged scale.
According to my invention I arrange centrally and below the ordinary grate a,
a fuel chamber or box, which is supported by the bars c c as shown in Fig. 1. On
each side of this chamber are arranged two grates d having slant sides and capable
of being raised and lowered by means of the racks e, formed integrally therewith

page_text: and of the pinions g gearing with the latter.
These pinions are actuated by means
of a detachable handle f. The box or chamber is normally covered by a perforated
plate or lid h, provided with a loop or staple and which is drawn out for the
purpose of feeding the fuel upwards, the fire being kindled in the first instance upon
the bottom of the fire grate, consisting of the plate hand of the bottom of the
grates d, which may be flush with this plate or otherwise, according as desired.
The fuel in the chamber b, is piled upon a platten i supported centrally by an upright
screw rod working in a mut k at the bottom of the box, this nut being provided
upon its outer periphery with teeth gearing with the worm l. The latter is mounted
upon the inner end of an axis m, supported by suitable bearings and carrying at its
outer end a hand wheel or crank n, whereby the worm and with it the nut k, and
the screw rod, can be operated and the platten raised or lowered. I may however
employ any other suitable mechanism to raise or lower the platten i and the grates d.
The latter are formed of bars having preferably the cross sectional shape shown in
Fig. 5, these bars serving for the bottom as well as for the sides of the said
grates.
For the circulation of air slots o o', are formed at the back of the box, a space
being likewise formed between the side of the fire place and the slant sides of the
grates as clearly shown in Fig. 4.
When the fire is getting low and requires replenishing with fuel which has been
preliminarily fed by hand in the chamber or box, the plate h, is merely withdrawn,
and as fast as the fuel is being consumed, the platten is raised until it reaches the
top of the box b, when the plate h, is inserted thereon into the grate to support the
fire in order that the platten may be lowered and the chamber or box refilled,
the plate h, being subsequently withdrawn again by means of a suitable iron furnished
with a hook at one end.
Instead of the plate h, I may use one or more plates passing through the sides of
the range or stove. My invention may likewise be applied to boiler furnaces in
which case the mechanism for raising and lowering the platten i may be actuated by
power instead of by hand.
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 :-
(1) In stoves, ranges, furnaces, and the like, the formation of a central fuel box
or chamber surmounted by a removable plate in combination with two side grates
which can be raised or lowered by suitable mechanism substantially as herein
described and shown, and for the purpose set forth.
(2) In stoves, ranges, furnaces and the like the arrangement of a central fuel
box or chamber such as above claimed wherein the fuel may be gradually fed up
from below into the fire for the purpose of replenishing the same substantially as
herein described and shown and for the purpose set forth.
(3) The improvements in stoves, ranges, furnaces and the like for smoke con-
suming purposes constructed arranged and operating substantially as herein described
and shown, and for the purpose set forth.
Dated this 23rd day of March 1891.
