I, JOHN WILLIAM CHEETHAM, of 27, Lincoln Street, Werneth, Oldham, Coal
Saver Manufacturer, do hereby declare the nature of my said invention to be
as follows:
My invention consists of a coal saver which hangs upon the outside of the bars
of a kitchen or like grate and is characterised by solid vertical bars about an inch
apart, and horizontal shell-like bars corresponding to, and fitting over, the range
bars, and which said coal saver is suspended by adjustable hooks or claws, by
preference, at or near either end or side, and if desired by fixed hooks at or near
the centre.
These adjustable hooks consist of small pieces of metal slightly bent and one
half slotted, and fitting against and over a, by preference, corresponding or similarly
slotted part of the back of the coal saver, where it is clamped by nut and screw.
The plain parts of these pieces of metal form the hooks or claws which take over
the fire-grate bars, and suspend the coal saver thereon. The rear face of the slotted
part and that of the coal saver may be fluted or roughened to firmly hold the claw
when clamped in position.
In lieu of using a separate screw and nut for fixing the hooks I may use the screw
threaded spindle of the knobs which serve for ornamenting and handling the coal
saver, but I prefer to employ separate screws.
To keep the range bars cool I form the horizontal bars which fit over them with
a longitudinal opening in the angle or edge thereof, and thus allow the cold air to
enter the grate through such opening and keep the range bars cool.
In addition to the aforesaid adjustable claws or hooks at either end, I may
employ one or more hooks on the length of the horizontal bars, fixed by small set
screws, and I may arrange them at different points longitudinally to suit the
proper mounting of the device.
Whilst the improved device is chiefly applicable as a coal saver for attachment to
existing ranges, may use it as a grate front for new ranges and make it either a
permanent or movable part of the range, substituting solid longitudinal bars for
the shell-like bars.
A further feature of my invention consists in forming the device with its upper
edge bevilled in order that it may be more readily lifted away from the range
bars.

I, JOHN WILLIAMm Cheetham, of 27, Lincoln Street, Werneth, Oldham, Coal
Saver Manufacturer, 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:―
My invention consists of a coal saver which, hangs upon the outside of the bars
of a kitchen 'or like grate and is characterised by solid vertical bars about an inch
apart, and horizontal shell-like bars corresponding to and fitting over, the range
bars, and which said coal saver is suspended by adjustable hooks or claws, by
preference, at or near either end or side, and if desired by fixed hooks at or near the
centre. These adjustable hooks consist of small pieces of metal slightly bent and
one half slotted, and fitting against and over a, by preference, corresponding or
similarly slotted part of the coal saver, where it is clamped by nut and screw.
The plain parts of these pieces of metal form the hooks or claws which take over
the fire-grate bars, and suspend the coal saver thereon. The rear face of the slotted
part and that of the coal saver may be fluted or roughened to firmly hold the claw
when clamped in position.
In lieu of using a separate screw and nut for fixing the hooks I may use the screw
threaded spindle of the knobs which serve for ornamenting and handling the coal
saver, but I prefer to employ separate screws.
To keep the range bars cool I form the horizontal bars which fit over them with
a longitudinal opening in the angle or edge thereof, and thus allow the cold air
to enter the grate through such opening and keep the range bars cool.
In addition to the aforesaid adjustable claws or hooks at either end, I may employ
one or more hooks on the length of the horizontal bars, fixed by small set screws,
and I may arrange them at different points longitudinally to suit the proper mount-
ing of the device.
Whilst the improved device is chiefly applicable as a coal saver for attachment to
existing ranges, may use it as a grate front for new ranges and make it either
a permanent or movable part of the range, substituting solid longitudinal burs for
the shell-like bars.
A further feature of my invention consists in forming, the device with its upper
edge bevilled in order that it may be readily lifted away from the range bars.
And in order that my said invention may be more readily understood and carried
into practical effect I have hereunto annexed a sheet of drawings and will now
proceed to describe the same with the various figures and letters of reference
marked thereon.
Fig. is a front view of the coal saving appliance constructed and fitted in accord-
ance with my invention. Fig. 2 is a vertical section and Fig. 3 is an end or edge
view of the saver and shewing its position when on the grate bars. Figs. 4, 5, 6
and 7 illustrate details separately.
As illustrated, the device consists of frame (A) with horizontal shell-like bars (B)
and vertical bars (C) forming a grate-like structure. The said frame (A) is counter-
sunk or bevilled on each side so as to readily fit the grate, and allow of the appliance
being readily lifted on and off the grate bars. The bars (B) are made hollow to
adapt themselves to the grate bars (D) and to keep such bars cool and to prevent
burning-out I form the bars (1) with one or more vents (BI).
The bars (C) are solid and project into the fire-space as far as possible so as to
keep the fuel from falling out, and for that purpose they may be arched, or placed
at the extreme edges of bars (B).

page_text: The bars (C) in the lowermost opening are fewer in number to allow of poking
the fire, or raking of ashes.
For hooking the device on to the grate I employ one, two or more of the devices
(or their equivalent) shewn in Figs. 4, 6 6 and 7.
The device shewn in Fig. 4 consists of a piece of metal strip (E) bent at or about
right angles, and by means of slot and set screw adjustably secured to the by
preference, top horizontal bar (1) as shewn in Fig. 1, so that the plain part may
readily hook on to the grate bar (D) as shewn in Fig. 3.
The device shewn in Fig. 5 (rear view and side view) is a strip of metal (F)
adjustably clamped by screw (FI) and nut (G) and, by preference, formed with a
fluted or roughened face corresponding to that on the shell or frame (A) so as to
ensure of the hook being retained in its proper position after once being fixed. The
Baid strip is so formed as to take into a groove (F²) in the back of the frame and so
be prevented twisting.
In Fig.
the hooks consist of bent pieces of metal (H) held by the screwed
spindle and nut of knobs (I) used for handling the appliance.
The device shewn in Fig. 7 consists of a flat piece of metal (J) capable of fitting
on the ends of frame (A) at any suitable point and clamped by screw (J).
Whilst I prefer only to use the device shewn in Fig. 5, I may also use the device
shown in Fig. 4, or I may supply the device with all the forms of hooks applied
so as to allow for the differences in spacing of grate bars, or the exigences of each
requirement.
Lastly, I may form the device with the bars (B) solid, and use the device as the
grate front itself, dispensing with the existing bars, and I may arrange for the
device to be removable for cleaning purposes with snugs or projections on the grate
sides by which to retain the device when in position, or I may use the handles for
switching or turning latches behind fixed parts of the grate front.
The bars (B) may be dispensed with and the bars (C) only used and suitably
shaped to accommodate the grate bars and in such form the device will be much
ligliter and allow of more fire being seen.
Having thus 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 desire
to secure by Letters Patent is:-
1: In a coal saver for domestic fire-places the combination of a counter-sunk
framo, horizontal shell-like bars with air vents, vertical bars projecting into the fire
space, and means for suspending said coal saver for grate bars, as set forth.
2: The combination of counter-sunk frame (A), shell-like bars (B) with
vents (B) and vertical bars (C) projecting into the fire space, as and for the pur-
poses set forth.
3:—Hooks (E), (F), (H) or (J), or their equivalent, as and for the purposes set
forth.
4: The combination of the appliance herein described with a kitchen range or
domestic fire-place, either fixed or removable, and serving as a substitute for the
ordinary grate bars, as set forth.
