PROVISIONAL SPECIFICATION.
Improvements in Adjustable Firegrates.
We, YATES HAYWOOD & Co. and THE ROTHERHAM FOUNDRY COY. LIMITED,
Rotherham in the County of York, Manufacturers, and SAM HAYWOOD of the
same address, Pattern Maker do hereby declare the nature of our invention to be
as follows:
This invention is applicable to the bottom grates of kitchen ranges, grills, and
other stoves, or fires.
The object is to provide a self supporting bottom grate that can be adjusted
to any desired height so as to increase or diminish the size of the fire, and
that will remain in position without the aid of catches, racks or other movable.
supports that require to engage, and to be disengaged by hand, and also to provide
a ready means of discharging the ashes from the grate into the ashes pan, or the
space under the grate.
In carrying out the invention we make the bottom grate with depending quadrant
shaped bearings, which rest upon a correspondingly curved radial supports or tracks,
the face of such tracks being either continuous or intermittent as may be found
most convenient for keeping them clear of ashes and enabling the grate to be readily
moved.
The frictional contact of these parts will in most cases retain the grate in any
position to which it may be moved. The back of the grate which connects the
points of the quadrant shaped bearings and forms the centre of the movement, may
be used as an axis if desired by extending the extreme ends and resting them in
bearings.
The back portion of the quadrant shaped bearings is made of such a weight as to
counterbalance the grate or thereabouts, and there is provision in the front of the
grate to receive a lever, or some equivalent device by which the grate can be raised
and lowered.
The front bars of the range or other fire place are correspondingly curved to the
sweep of the bottom grate.
By lowering the grate below the bottom of the front bars, the cinders and ashes
will drop off, into the ashes pan or opening under the grate.

COMPLETE SPECIFICATION.
Improvements in Adjustable Firegrates.
We, YATES HAYWOOD & Co. and THE ROTHERHAM FOUNDRY COY. LIMITED,
Rotherham in the County of York, Manufacturers, and SAM HAYWOOD of the
same address, Pattern Maker, 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 is applicable to the bottom grates of kitchen ranges, grills, and
other stoves, or fires.
The object
to provide a selfsupporting bottom grate that can be adjusted to
any desired height, so as to increase or diminish the size of the fire, and that will
remain in position without the aid of catches, racks, or other movable supports that

page_text: require to engage and to be disengaged by hand; and also to provide a ready means
for discharging the ashes from the grate into the ashes pan, or into the space under
the grate.
And in order that our invention may be clearly understood, we have annexed a
sheet of drawings illustrating the way it may be carried into effect.
Fig. 1, is a sectional view or side elevation of the adjustable grate with its
adjacent parts, in its highest position.
Fig. 2, a similar view with the grate lowered.
Fig. 3, perspective view of the grate.
In carrying out our invention as illustrated in the drawings we make the bottom
grate A, of a curved or partly curved form to retain the fuel, when adjusted to its
highest or lowest angles, and at each end we form depending segmental bearings B,
which rest upon correspondingly curved supports or tracks C, the face of such
supports or tracks being either continuous or intermittent as may be found best
adapted for keeping themselves clear of ashes and so permitting the easy adjustment
of the grate.
The frictional contact of the face of the bearings B, upon the face of the
supports C, is found sufficient to retain the grate A, in any position to which it may
be moved.
The back portion D, of the grate A, which forms the centre point of the move-
ment of the grate, may be extended at each end and be used as an axis if desired,
in which case the ends would rest in bearings.
The back portion of the bearings B, is made of such weight that it will form a
counterbalance to the grate, and we make a socket E, in the front of the grate,
preferably to fit between the bars of the front grate, with a hole to receive the end
of the poker, or a lever, or other device by which the grate A, may be either raised
or lowered. The front bars F, of the range or other fire place, are curved to
correspond with the sweep of the bottom grate.
When the bottom grate is lowered below the bottom bar of front grate bars, the
cinders and ashes drop off by gravity, or may be readily raked or shaken off.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed or carried into effect,
we declare that what we claim is :-
1-In kitchen-ranges, grills, and other stoves or fires, an adjustable bottom-grate
baving segmental side bearings, resting upon curved supports or tracks, and capable
of moving thereon, substantially as bereinbefore described, for the purpose specified.
2-In kitchen-ranges, grills, and other stoves or fires, a bottom-grate having a
slightly curved up front, depending segmental bearings resting upon curved supports
or tracks, and capable of a sliding movement thereon, by which the grate is raised
or lowered, a front socket or other equivalent means by which the grate is moved,
and a counterbalance weight for the grate, all arranged and combined, substantially
in the manner as hereinbefore described and shown.
