IMPROVEMENTS IN OPEN FIRE GRATES OR STOVES
Year: 1884

page_text: I SAMUEL PICKERSGILL of Star Foundry Eagle Street Derby in the County of
Derby Stove Grate Manufacturer do hereby declare the nature of my Invention
for IMPROVEMENTS IN OPEN FIRE GRATES OR STOVES to be as follows:-
To facilitate the heating of the apartment in which the fire place is applied also
to economise fuel and to prevent ashes or fire falling through the bars on to the
hearth as in the ordinary fire place and to promote perfect combustion and consume
the greater part of its own smoke. For this purpose the bars at the front are so
bevelled inwards as to make it impossible for the ashes either to lodge on or fall
through them on to the hearth but will be thrown forward into the fire where it is
either consumed or falls to the bottom which is provided with a secret ashespan which
inay be removed at any time without the least dust. The bottom of the fire place
is formed partly of iron bars (so constructed as to throw the little refuse made into
the secret ashespan before named) and partly of fire brick and is attached to the
back which is also of fire brick shaped so as to stand into and contract the fire
space for four or five inches high from thence receeding forming the ordinary shape
fire space for several inches higher after which it falls towards the fire thereby
burning much smoke and sending the heat right into the room.
The bottom of the fire place instead of being formed of part grate and part fire
brick may also be formed wholly of fire brick in which case it retains the same
shape as when part iron is used the ashespan will not then be required as all the
refuse is thrown under the hottest part of the fire and if not wholly consumed
leaves but little to be removed after a days fire has gone out. The sides of the
fire are also formed of fire brick and the whole fixed in an iron frame work or
back.
I SAMUEL PICKERSGILL of Star Foundry Eagle Street Derby in the County of
Derby Stove Grate Manufacturer do hereby declare the nature of my Invention
0 for IMPROVEMENTS IN OPEN FIRE GRATES OR STOVES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :—
Figure 1 is a front view of a grate or stove arranged according to my Invention,
Fig. 2 a vertical section on line A B when part grate and part brick is used for the

page_text: bottom, Fig. 3 a horizontal section of the same on line C D. Fig. 4 is a vertical
section on the line A B when all fire brick is used for the bottom, in each of the
views the same letters represent corresponding parts whereever they occur.
e e e e¹ are the front bars bevelled or sloped inwards as shown to prevent the
tendency of the ashes or fire to fall out and to throw them forward into the fire e¹
the bottom bar is formed with a front plate e' to which is attached the secret
ashespan this front plate is perforated to admit air to the bottom of the fire through
the bars or grated bottom g g g¹ this grated bottom is formed of three bars to a
radius with the back part h, but may consist of a greater or less number of bars,
and is cast in one piece. Joining at g with the pan gå in which the back brick h
is cemented or otherwise fixed and is for the purpose not only of admitting the right
amount of air to the fire as is needed to fully carry out the consumption of the
fuel but by its shape in conjunction with the other parts herein described, to
deposit the refuse from bad coal into the secret ashespan f, the back part of the
bottom, is of fire brick joined to the fire brick back k, and it is in this back
wherein lies the chief part of my Invention, the rounded swell ke filling up a large
space at or near the bottom of the fire and throwing the fire to the front bars and
thus the heat into the room and thereby effecting a great saving in fuel, the space
is widened out above this swell at k² to the usual width and terminates at k³ with
an overhanging portion as shown tending further to throw the heat into the room
and holding the smoke over the fire consuming a great portion which would
otherwise escape into the chimney. The sides 1, are also of fire brick but separately
considered do not form part of my Invention. The whole is fixed or held in place
by an iron frame work or back m, and back moulding m¹ but this separately does
not form part of my Invention. I also in some cases make the bottom g. h. wholly
of fire brick in which case I retain the same form or shape as when part iron, as
shown at Fig. 4.
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 The shape of the fire brick back with the rounded swell at or near the
bottom of the fire and the overhanging part in conjunction with the same, the
whole forming the back of the fire chamber.
2nd The combination of the grate and brick bottom with the secret ashespan, of
the shape and arrangement substantially as hereinbefore described and illustrated
in the accompanying Drawings.
3rd The shape-of-the-front-bars to prevent ashes or fire falling out on to the
hearth substantially as hereinbefore described and illustrated in the accompanying
Drawings.
