MENTS IN STOVE GRATES."
"IMPROVE-
My Invention relates to improvements in Stove Grates, and more particularly to
independent Stove Grates standing in recesses, and intended to be withdrawn
when occasion requires-The principal objects of my invention are in the first
place, the utilization of the heat of the fire, to the greatest extent possible, this
being accomplished, by the aid and arrangement of reflecting, and radiating surfaces;
and secondly to facilitate the removal, and replacement of the Grate, and by the
novel arrangement of the smoke flue at its junction with the entrance to the
chimney, to easily and effectually seal the said junction.
In carrying out my invention in the construction of a stove grate arranged to
stand independently in a recess, which recess may be formed of metal or be tiled
or otherwise finished; I fit to the top of the recess a metal plate provided with
a suitable opening to the chimney, the said opening is surrounded by a depending
flange, the back portion of the flange being deeper or lower than the front portion-
The top of the smoke flue attached to the grate, is of sufficient height, to abut
against the flange of the top plate, and the back part of the flue being made lower
than the front part of the flange, it passes under and fits against the inside of the
back of the flange, to which it corresponds in shape; and the front part of the flue,
being of sufficient height, fits closely round and against the front or outside surface
of the flange, thus effectually sealing the junction of the flue to the chimney-I
prefer to make the backs of the flange and flue, the shape of half an elipse, and the
front, of a segment of a circle, such shape being found very suitable for the required
purpose of selfadjustment-Over and partly round the fire, I fix one or more

otherwise ornamented, for the purpose of reflecting the heat of the fire into the
room; a suitable valve or door giving egress to, or closing the flue-The back and
underparts of the Stove act as radiating surfaces. Underneath the fire, above the
lower part of the stove I insert an ashes pan projecting in front of the fire, over
which I place a perforated grid.
Air may be admitted through openings in the front of the stove-grate, passing
round or through the firebrick sides, and finally discharged into the fire, through
perforations in the firebrick back, for the purpose of assisting the combustion of the
gases.
Fresh air may be admitted underneath the stove, and being beated by contact
with the warm surfaces of the stove, will pass from the recess direct into the room..

HENRY HOYLES of Upperthorpe, Sheffield in the County of York, " IMPROVE-
MENTS IN STOVE GRATES."
. My Invention relates to improvements in Stove grates, and more particularly
to independent stove grates standing in recesses and intended to be withdrawn
from such recesses when occasion requires. The principal objects of my invention
are, first, the utilization of the heat of the fire to the greatest possible extent, and
secondly to enable such stove grates to be removed from their normal position,
and replaced with the greatest facility.
The first object I accomplish by the aid and arrangement of reflecting and
radiating surfaces, and the second by the novel construction of the smoke flue at
its junction with the entrance to the chimney. And in order that my invention
may be fully and clearly understood I will proceed to more particularly describe
the same, and for that purpose shall refer to the annexed sheet of drawings, simply
premising that the same letters of reference indicate corresponding parts in all the
figures.
Fig. 1. represents an elevation or front view of a Stove Grate, made according
to my invention.
Fig. 2. is a sectional side Elevation.
Fig 3 is a plan of the smoke flue and entrance to chimney.
In carrying out my invention, I fit to the top of the recess (which may be
formed of metal, or be tiled, or otherwise decorated and finished) a metal plate A
provided with a suitable opening to the chimney; the said opening is surrounded
by a depending flange B, the back portion b being deeper than the front b'. The
top part of the smoke flue C, which is attached to the stove Grate, is of sufficient
height to abut against the depending flange B in the following novel manner; the
back part of the flue c' is made lower than the front part c¹¹ so that it passes
under the front part of the depending flange b', and abuts against the inside of
the lower part b, at the same time the front part c¹¹ fits closely round the front or
outside surface of the depending flange b'; the various parts correspond in shape,
and thus effectually seal the junction of the flue to the chimney. I prefer to make
the back parts of the flange and the smoke flue c¹ and b, of the configuration of
half an elipse, and the front parts c" and 6', of a segment of a circle, such shape or
configuration being found most suitable for the required purpose of rapid
adjustment.
Over and partly round the fire D, I fix one or more polished metallic plates E
baving either concave or flat surfaces, plain, fluted or otherwise ornamented, for the
purpose of reflecting the heat of the fire into the room; a suitable valve or door F
giving egress to, or closing the smoke flue C.-The back and other parts of the
stove grate act as radiating surfaces. Immediately underneath the fire grate I
insert an ashes pan a portion of which projects in front of the fire, and which I
prefer to cover with a perforated grid G.
Air may be admitted through openings H in the front of the stove grate, passing
round or through firebrick sides, and finally discharged into the fire through
perforations I in the firebrick back, for the purpose of assisting the combustion of
the gases.
As an adjunct, an air passage or flue J may be constructed so as to bring fresh
air to the underside of the stove, and being heated by contact with the warm
surfaces it will pass from the recess direct into the room.

page_text: Having now described and particularly ascertained the nature of the said
invention and the manner in which it may be carried into effect, I would observe
in conclusion that what I consider to be novel and original, and therefore claim as
the invention secured to me by the hereinbefore in part recited Letters Patent,
is,
"
First. The construction and use, of independent Stove Grates, 'having a smoke
flue, reflector or radiator, and ashes pan with grid, for the purpose, and
substantially as described and illustrated or any mere modification in the design
thereof.
Second, The use of a pendent flange B, corresponding to the top of a smoke
flue C, for the purpose, and substantially as described and illustrated.
In Witness whereof I the said Henry Hoyles, have hereunto set my hand
and seal this thirteenth day of June, in the year of our Lord, one thousand
eight hundred and eighty three.
