PROVISIONAL SPECIFICATION.
Improvements in or relating to Domestic and other Fire Grates.
I, SAMUEL OCTAVIUS FERRY, of 10 Malvern Street, Newcastle-on-Tyne, i
the County of Northumberland, Engineer, do hereby declare the nature of this
invention to be as follows:-
Heretofore domestic and other. fire grates have usually been so constructed that
the fire can only be replenished from the top. Now my invention has for its
object to provide means whereby this may be effected from the bottom upwards,
the general arrangement of the upper part of the grate remaining unchanged, so
that the fuel may be fed into it from the top as heretofore when found desirable
and necessary, such for instance as when starting the fire.
The means I adopt for this purpose I will now proceed to describe as applied to
a domestic fire grate of the usual type, and from such description it will be
perfectly understood that this, modified in detail, may be easily applied to other
fire grates.
For this purpose the usual bottom to the grate is dispensed with and the back
increased in depth so that it extends for a considerable distance below the bottom
bar of the front. This extended portion of the back is curved forward in such
a manner that it forms a segment of a circle the centre of which is immediately
below the bottom of the grate front, at which point a horizontal spindle is so
arranged that its axis coincides with said centre.
Mounted on this spindle is a hollow segmental hopper of such size that it
extends from side to side of the grate and its under surface slides on the surface of
the curved extended portion of the back of the grate.
Hinged on the same spindle as this hopper is a plate of the same shape and
size as the interior of the former and suitable hand or treadle levers, or other
means, are provided to swing the plate and hopper into any desired position.
In supplying fuel to the combustion chamber by the aid of the above described
device, the hopper is swung forward to a suitable extent and the hinged plate then
turned outward and upward into a position in which it will be free of the hopper.
The fuel is then fed into the hopper and the hinged plate turned downwards into
a position where it may be used for forcing the fuel into the combustion chamber.
When the stroke is completed the hopper, which has been carried inwards, is
withdrawn, the hinged plate and the fuel remaining stationary until a fresh
supply of fuel is required, then the hinged plate is raised and the operation is
repeated.

page_text: Improvements in or relating to Domestic and other Fire Grates.
I, SAMUEL OCTAVIUS FERRY, of 10 Malvern Street, Newcastle-on-Tyne, in
the County of Northumberland, 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:-
Heretofore domestic and other fire grates have usually been so constructed that
the fire can only be replenished from the top. Now my invention has for its object
to provide means whereby this may be effected from the bottom upwards, the
general arrangement of the upper part of the grate remaining unchanged, so that
the fuel may be fed into it from the top as heretofore when found desirable and
necessary, such for instance as when starting the fire.
The means I adopt for this purpose I will now proceed to describe as applied to
a domestic fire grate of the usual type, and from such description it will be
perfectly understood that this, modified in detail, may be easily applied to other
fire grates.
For this purpose the usual bottom to the grate is dispensed with and the back
increased in depth so that it extends for a considerable distance below the bottom
bar of the front. This extended portion of the back is curved forward in such a
manner that it forms a segment of a circle the centre of which is immediately
below the bottom of the grate front, at which point a horizontal spindle is so
arranged that its axis coincides with said centre.
Mounted on this spindle is a hollow segmental hopper of such size that it
extends from side to side of the grate and its under surface slides on the surface
of the curved extended portion of the back of the grate.
Hinged on the same spindle as this hopper is a plate of the same shape and
size as the interior of the former and suitable hand or treadle levers, or other
means, are provided to swing the plate and hopper into any desired position.
And in order that my invention may be more readily understood and carried
into practice I will now proceed to describe the same with reference to the
accompanying drawings, as applied to a domestic fire grate.
Of these drawings-
Fig. 1 is a front elevation,
Fig. 2 a side sectional elevation, and
Figs. 3, 4, and 5 part side sectional elevation showing different position of the
movable parts.
The ordinary bottom of the grate is dispensed with, and the back a continued
downward beyond the point at which the grate bottom would be ordinarily situated,
and the extended portion al curved forward so that it forms a segment of a circle
the centre of which coincides with the axis of a horizontal spindle 6 mounted to
revolve in suitable bearings immediately below the grate front c.
Fixed on the spindle is a hollow segmental hopper d of such size and shape
that it extends from side to side of the grate and its under surface slides on the
surface of the curved portion a' of the grate back a.
On this spindle is also mounted loosely a sector-plate e of the same size and
shape as the interior of the hopper d suitable handles f,f being provided whereby
the hopper and plate may be operated independently of one another.
In supplying fuel to the combustion chamber by the aid of the above described
device, the hopper is swung forward to a suitable extent and the hinged plate then
turned outward and upward into a position in which it will be free of the hopper,
as shown in Fig. 3. The fuel is then fed into the hopper and the hinged plate
turned downwards into a position where it may be used for forcing the fuel into
the combustion chamber as shown in Fig. 4. When the stroke is completed, the

page_text: hopper, which has been carried inwards, is withdrawn, the hinged plate and the
fuel remaining stationary, as shown in Fig. 3 until a fresh supply of fuel is
required, when the hinged plate is raised and the operation is repeated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
(1) A fire grate provided at its lower end with hopper d and plate e arranged
constructed and operating substantially as and for the purpose described and
illustrated in the accompanying drawings.
(2) In a fire grate the combination of a hopper d and plate e arranged con-
structed and operating substantially as and for the purpose described.
