PROVISIONAL SPECIFICATION.
Improvements in Fire-grates or Stoves.
We JOSEPH SHUBROOK, of No. 9 Gracechurch Street, in the City and County
of Loudon, Accountant, and WILLIAM BENJAMIN BELEMORE, of No. 6 Hutton
Terrace, Jesmond, Newcastle-upon-Tyne, in the County of Northumberland,
Architect and Surveyor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in fire-grates or stoves, portable or fixed,
and it consists in certain constructions whereby fuel may be fed into the grate so
that its combustion may take place downwards thereby utilizing the gases arising
therefrom, affording a better radiation of the heat generated than the ordinary
grate together with consumption of smoke when the fire is active.
We may make our fire-grate or stove with a reversible fuel basket or grate,
preferably barrel shaped, having closed sides and back and barred front, the whole
being hung upon horizontal pivots so as to be capable of being turned upon a
carriage or within a fixed chamber. The top and bottom of this reversible grate
are hinged or so fitted that they may be raised or opened for the introduction of
the fuel, and upon the front of the fuel-grate we provide a projecting lug or other
suitable means by which it may be secured in a vertical position when charged
with fuel. The chamber or carriage we provide with a horizontal bar upon which
the front pivot of the reversible grate turns, a suitable bearing being formed at
the back of the chamber for the back pivot. Immediately beneath this horizontal
bar and upon either side of the reversible grate we provide suitable winged buttons
or stops for the purpose of locking the fuel-grate when turned, the hereinbefore
mentioned projecting lug formed upon the front of the reversible grate entering a
corresponding recess formed on the horizontal bar, where it is securely held by
a hinged button or otherwise. We may however modify these means of reversing
the fuel-grate and securing it in position. If the fuel-grate has a barrel shape, by
giving to the bellied side opposite the projecting lug a greater thickness of metal
than its corresponding bellied side the additional weight will give the fuel-grate a
tendency to always assume its proper horizontal position-so as to facilitate the
locking of the fuel-grate.
In a stove or fire-grate of this construction the operation of replenishing the fire
after it has been in action will be as follows:-The top hinged grate being opened,
coal is put on to the top of the fire, this hinged grate is then let down and secured,
the fuel-grate is then released from its fastening and turned over so that the part of
the fire-grate containing the fresh fuel is brought undermost, the hinged grating
which then comes to the top is thrown open and the operation is complete.
Assuming that in this replenishing, the fuel-grate has made a half turn from left to
right, in the next replenishing operation it will be turned back again from right to
left, and so on. A suitable tool or adjuster is provided for bolting grates, turning
fire grate, and adjusting hinged or winged buttons.
We may construct the fixed part of the fire-grate or stove in any suitable
manner.

In a stove or fire-grate of this construction the operation of replenishing the fire
after it has been in action will be as follows:-The top hinged grate H being
opened, coal is put on to the top of the fire, this hinged grate H is then let down and
secured, the fuel-grate A is then released from its fastening N and turned over
(by inserting a lever in the socket a, or a', by the aid of a lever on the pivot F', or
otherwise) so that the part of the fire-grate containing the fresh fuel is brought
undermost, the hinged grating I which then comes to the top is thrown open and
the operation is complete. Assuming that in this replenishing, the fuel grate A
has made a half-turn from left to right, in the next replenishing operation it will
be turned back again from right to left and so on.
For turning the grate we may use a lever fixed on the front pivot F' and which
when not operating the turning may be held in a spring or other catch on each side
of the fire place, or we may use any suitable tool for this purpose as also for
bolting grates and adjusting hinged or winged buttons.
We may construct the fixed chamber or the carriage of the grate or stove in any
suitable manner and of any suitable material or combination of materials.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. An improved fire-grate or stove composed of a reversible fuel-basket or grate
having closed sides and back, barred front and hinged or movable top and bottom,
the whole being hung upon horizontal pivots within a fixed chamber or a carriage
in such a manner that the basket or grate may be reversed after placing a fresh
supply of fuel upon an active fire and a downward combustion thereby obtained,
substantially as described.
2. A fire-grate or stove constructed, combined and arranged to operate as
hereinbefore described with reference to the accompanying drawing.
