PROVISIONAL SPECIFICATION.
Improvements connected with Domestic Stove Grates for Burning
Anthracite Coal.
I CHARLES TALMAGE BASTAND of 21 King Henry's Road, Regents Park,
London, Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements connected with domestic stove
grates for burning anthracite coal.
For the purpose of my invention I construct an ordinary form of open grate with
a lower back grating or side gratings and I stop up the register part except to a
slot or opening into the flue at a slight distance above a damper which I fit to close
or to open the flue. The lower part of the flue terminates about level with the ash
pit which has a door at the back.
In first lighting the fire the damper is opened so that the smoke from the wood
is drawn through the back or side lower gratings into the flue. As soon as the fuel
is well alight I close the damper and allow the escaping gases etc. to pass by the
upper slot into the flue. The fire can be recharged with fuel as occasion requires
without the damper being interfered with.
A fire from anthracite coal is almost incandescent and gives off great heat.
The invention is applicable for kitcheners and other ranges as well as for ordinary
domestic purposes.

COMPLETE SPECIFICATION.
Improvements connected with Domestic Stove Grates for Burning
Anthracite Coal.
I, CHARLES TALMAGE BASTAND, of 21 King Henry's Road, Regents Park,
London, 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 :-
This invention relates to .certain improvements connected with domestic stove
grates for burning anthracite coal.
For the purpose of my invention, I construct an open grate with a back grating
or side gratings in the fire basket leading to a back Hue, and I stop up the register
part except to a slot or opening into the flue at a slight distance above a damper,
which I fit to close or to open the flue. The lower part of the flue terminates about
level with the ash pit which has a door at the back for clearing out purposes and
for entrance of air when desired.
My invention will be understood by an examination of the annexed drawings.
Figure 1 front elevation of an open stove.
Figure 2 section of same.
A is the fire basket with sloping front bars B, and with open grate bars C, C, at
back to lead the products of combustion into the flue D. E is a baffle or damper
in flue D to regulate passage of products into chimney F or to shut off the
communication when desired by the handle G and rod. H. I is a passage in upper
part J of stove for gaseous vapour to flow from above the fire into the chimney F.

represents a valve within the ash pit K, which valve can be opened for removal
of ashes from the base of the flue D, and also for regulating a current of fresh air
into the flue for reducing the heat of, the fire and for checking the draught through
the fire when necessary. L is a canopy over the front of the fire basket A for
collecting the escaping vapours previous to their exit by the passage I.
M, M, are air holes in the front side cheeks N, N, of the stove, and P, P, are
other air holes in upper front of stove, for the escape of the air which entered at M
and becomes warmed in its passage in the air chamber R, said air in a warm
condition passing from the grating P into the room in which the stove is fitted.
The behind part of the stove is boxed in by the screen Q to form an air heating
chamber R.
The stove is preferably made in complete condition and to enable it to be "sett
in the recess, it is provided with rollers S for the purpose.
"
The stove thus constructed is specially adapted for burning anthracite (smokeless),
and other hard coal.
I find in practice that by first laying pieces of anthracite coal of about the size
of walnuts on the bottom grate and then to cover the same with paper and dry wood
upon which a second layer of coal is placed, then some more paper and wood, and
finally more coal to fill up the fire basket A, I can obtain a rapid ignition, which
in a short time will enable the damper E to be closed,. so that all vapour escaping
from the fire can pass through the channel I. From this moment, the fire will
continue to burn under slow combustion for many hours without the least
attention.
Anthracite coal when properly burnt, and as is accomplished by my construction
of stove gives off no smoke, it produces no cinders, but it has a dust residue, which
falls into the ash pit K for after collection.
I may use a front screen to the ash pit for enclosing the ashes and to prevent
the dropping fuel in the fire basket from falling out in front. I form my bars B, B,
to slope downwardly in the basket.
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 :-
1. The construction of open fire stoves as shown by the annexed drawings for
the burning of anthracite, and other hard coal in the manner described.
2. Constructing an open stove with bars B, B, at front and C, C at back, of fire
basket with damper E, canopy L, and passage I, all arranged in the manner and
for the purposes herein before explained.
