Improvements in Cooking Ranges and Stoves.
I, JOHN EYRE, RUSSELL, Ironfounder, of Peel Foundry, Derby, in the County
of Derby, do hereby declare the nature of this invention to be as follows:-
The desirability of being able to raise the grate bottom of a cooking-range
and other stove, in order to reduce the size of the fire, is well known, and
many attempts have been made to effect this object.
In most cases, it has been usual to hang the bottom at the back on pivots
in an inclined position, to raise the front (the front bars being vertical)" by a
mechanical device of some kind, in order to reduce the size of the fire.
It has also been proposed to raise the bottom for the same purpose with a
parallel motion, this object being attained by a complicated system of mechanism
the cost of which is prohibitive.
Now the object of this invention is to provide for the raising of the grate
bottom with a parallel motion in a simple and efficient manner, whether the
front bars are vertical or horizontal, and the invention consists in the adapta-
tion to the grate bottom, of a pendent piece suitably arranged to work in
guides, means being provided to secure the bottom at any desired height.
In carrying out this invention, I attach to the front edge of the grate
bottom, a frame or plate, which will be at right angles to the bottom and
pendent therefrom.
At the lower edge of this frame, lugs are provided, to take into notches, or
onto pieces arranged in the cheeks of the fireplace.
This frame slides loosely in grooves formed in the cheeks of the fireplace,
in the rear of the front bars, which may be horizontal; or it may be, that
the front har of the bottom is forked at either end, to work on guide bars at
the sides of the fire-place, in front of the front bars, if they be vertical.
In operating this grate bottom, it will be only necessary to insert the poker
in a hole provided in the bottom bar of the frame.-push it back, to clear the
lugs from the notches or pins, then raise it with the grate bottom, and, when
at the desired height, draw the frame forward again, that the lugs may engage
with the notches or pins. The tendency will be for the bottom to tip back-
wards, which will serve to keep the lugs in engagement with the pins without
other means.
Stops in the cheeks will support the grate bottom, when in its lowest position.

I, JOHN EYRE RUSSELL, Ironfounder, of Peel Foundry, Derby, in the County
of Derby, 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:-
The desirability of being able to raise the grate bottom of a cooking range
or other stove, in order to reduce the size of the fire, is well known, and many
attempts have been made to effect this object.
In most cases, it has been usual to hang the bottom at the back on pivots in
an inclined position, and to raise the front (the front bars being vertical) by
a mechanical device of some kind, in order to reduce the size of the fire.
It has also been proposed to raise the bottom, for the same purpose, with a
parallel motion,-this object being attained by a complicated system of mechanism,
the cost of which is prohibitive.
The object of the present invention is to provide for the raising of the grate
bottom with a parallel motion in a more simple and efficient manner than here-
tofore, whether the front bars are vertical or horizontal.
In carrying out this invention, I attach rigidly to the front edge of the grate
bottom, a frame or plate which hangs below the bottom at right angles thereto.
At the lower edge of this frame, lugs are provided to take into notches or
onto pieces arranged in the sides of the fireplace below the fire.
This frame slides loosely in grooves formed in the cheeks of the fireplace in
the rear of the front bars, which may be horizontal, or it may be that the
front bar of the bottom is forked at either end, to work on guide bars at the
sides of the fire-place in front of the front bars, if they be vertical.
Referring now to the accompanying drawings, wherein I have shewn my
invention:-
Figs. 1 and 2 are perspective elevations shewing the lifting grate bottom at
its middle and lowest points, respectively.
Fig. 3 is a perspective elevation of the cheek of the grate.
Fig. 4 is a side clevation, with the lifting grate bottom in its lowest position.
Fig. 5 shews the lifting grate bottom detached.
is the grate bottom, and b a rectangular frame pendent from the front
thereof, at right angles thereto. are vertical guides (one only of which
appears in the drawing), wherein the frame bloosely slides. are pins or
studs arranged in vertical rows on the side plates e, beneath the fire, and so
placed as to engage with lugs f on the frame b, and thereby hold the grate
bottom at the desired elevation.
In operating this grate bottom, it will be only necessary to insert the poker
in a hole g, provided in the bottom bar of the frame b, and push back the
frame b, to clear the lugs f from the pins d.
The frame will then be free to raise or lower the grate bottom to the desired
height. at which it is secured by drawing the frame forward again, so that the
lugs engage with the nins d, as before. The weight of the bottom, and the
fire thereon, serves to press forward the frame b, and thereby keep the lugs f in
engagement with the pins d, without other means.
Stops h h in the cheeks will support the grate bottom when in its lowest
position.

page_text: 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. A lifting grate bottom for ranges and stoves operated, substantially as
described, by means of a frame pendent from the grate bottom, at the front,
in the manner set forth.
2. A horizontally arranged lifting grate bottom for ranges and stoves, having
a pendent attachment sliding in vertical grooves in the side plates, which
grooves extend below the fire, substantially as set forth.
