Improvements in Coal Saving Devices for Kitchen and other
Grates.
I, EDWARD WILLIAM BANNER of 5 Lytham Road, Marshside, Southport in
the County of Lancaster, Ironmonger do hereby declare the nature of this
invention to be as follows:-
Various devices have hitherto been employed for preventing coal falling through
the front bars of kitchen and other grates but these have all been more or less
defective, those which are placed inside the grate being fully exposed to the fire
get burned and also prevent the fire coming to the front, and others placed on the
outside of the bars being formed in one piece and having fixed. sides cannot be
adjusted to suit various widths of grate and distances between the bars.
Now my improved device which forms the object of this invention consists of
two or more separate pieces adapted to fit outside the bars and so formed that they
can be made to fit various sized grates.
A
In carrying out this invention, I cast or otherwise attach a number of vertical
ribs extending downwards at suitable distances apart to a cross bar which fits the
underside of the grate bar, this cross bar having two hooks to hook on to the grate
bar. These hooks carry another set of vertical upwardly extending ribs having a
cross bar at the top. This portion is preferably arranged to come between the
two top spaces of the bars and is fixed by simply hooking it on to the top bar.
separate set of ribs with a cross bar is used for the lower space which is also fixed
in position by means of hooks fitting onto the grate bar, the spaces between the
vertical ribs in the space above being sufficiently wide apart to allow the hooks to
pass between. Another arrangement consists in forming, in combination with a
single row of vertical ribs such as herein before described, an inward extension of
horizontal ribs or bars at a lower level which serves as a false bottom for the grate,
this extension by its weight keeps the vertical ribs in position between the front
bars, thus dispensing with the hooks, a second row of ribs extending upwards may
if desired form part of this combination which will then act both as a false bottom
for the grate and as a coal saver occupying two spaces between the bars. Provision
is made in this latter for attaching a set of ribs below if required. The ends of
each set of vertical ribs are so formed that pieces can be readily broken or cut off
to make them fit various widths of grate which is an important feature of this
invention, and each separate set can be readily removed independent of the others
and for the purpose of cleaning they can all be removed, this being done from the
front of the grate. This improved coal saver can be cast in or stamped out of any
suitable metal and may if necessary be slightly altered in shape from those above
described.

Improvements in Coal Saving Devices for Kitchen and other
Grates
I EDWARD WILLIAM BANNER of 5 Lytham Road, Marshside, Southport in
the County of Lancaster, Ironmongers Salesman 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 :—
Various devices have hitherto been employed for preventing coal and large
cinders falling through the front bars of kitchen and other grates but these have
all been more or less defective; those which are placed inside the grate, being
fully exposed to the fire, get burned, and also prevent the fire coming to the front
and others being placed on the outside of the bars, being formed in one piece and
having fixed sides cannot be adjusted to suit various widths of grate and distances
between the bars. Another defect of coal savers hitherto employed is that they
Cannot be easily removed, which is often necessary for making toast, heating flat
irons and doing roasting work. Now one object of my invention is to obviate
these objections and produce a coal saver that can be made to fit almost any sized
grate.
In the drawings
. Fig. 1 is a front elevation of the bars of an ordinary kitchen grate having my
device applied thereto.
Fig. 2 is a section on line za Fig. 1.
Fig. 3 is a similar view to Fig. 2 showing the arrangement of false bottom
hereinafter described.
Figs. 4, 5, & 6, which are drawn as half size the other figs. show a modification.
I have shown the device as applied to a grate having four bars A A' A' A³ of
which A is the fall-bar pivotted as at a to the sides of the grate. These bars are
shown square in cross section but it will be evident that the invention is not limited
to this number and shape of bars.
Referring first to Figs. 1 and 2.
In carrying out this invention I cast or otherwise attach a number of vertical
ribs B extending downwards at suitable distances apart, to a cross bar C which fits
against the underside of the grate bar A'; this cross bar C having two hooks D
to book onto said grate bar. Cross bar C also carries another set of vertical
upwardly extending ribs E having another cross bar C at the top.
This portion of the device is preferably arranged to come as shown between the
two top spaces of the bars and is fixed by simply hooking it onto the second bar A'.
A separate set of ribs B' with a cross bar C is used for the lower space and is
also fixed in position by means of hooks D' fitting onto the grate bar A³, the
spaces between the vertical ribs B in the space above being sufficiently wide apart
to allow the hooks D to pass between.
It will readily be seen that if the length of ribs B B E does not exactly
correspond with the spaces between the grate bars it will not materially affect the
efficiency of the device whereas in many of the former coal savers which were in
one piece and formed so as to fit or partially embrace two or more bars an error in
the distance allowed would make an effective fit impossible.
Referring now to Fig. 3.
Where it is desired to use a false bottom with the object of lessening the
capacity of the grate my arrangement consists in forming in combination with a
single row of vertical ribs B, an inward extension of horizontal ribs or bars Fat
a lower level, which serves as a false bottom for the grate and this extension F by
its weight and leverage keeps the upper edge of the vertical ribs B in position
against the lower edge of grate har A thus dispensing with hooks. A second row

page_text: of ribs B or an extension of those shown may if desired be also employed to_fit
the next space above A cross bar C is used to connect the inner ends of bars F.
Referring now to Figs. 4, 5, and 6.
The vertical ribs B and cross bar C³ are similar to those already described and
are attached by hooks D, say to the bar A*. A continuation of the ribs B¹
preferably in the form of a plate G may be provided having a hole g which
enables the device to lie flat in case the grate be provided with a projecting knob
or knobs for the draw out shelf, as is sometimes customary. This portion of the
device may be unhooked from the position shown in Figs. 4 and 6 and replaced on
the bar at an angle of 90 degrees to its former position as seen in Fig. 5 and will
then serve as a trivet for supporting a Dutch oven, flat iron or other article.
The improved coal saver may be cast in or stamped out of any suitable metal or
material and may if necessary be slightly altered in shape from the forms shown
and described.
The hooks or other parts may be so made that they can be bent open or closed
to fit different sizes of grate bars.
Having now 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
claim is.
1. A coal saving device for kitchen and other grates comprising two or more
separate cross bars carrying sets of vertically projecting ribs, and having means.
such as hooks for attachment to the grate bars in such manner that the spaces
between said grate bars or some of them are subdivided by said ribs substantially
as described and shown and for the purposes set forth.
2. In a coal saving device the combination of a false bottom and vertical ribs
for abutting against the grate bars and holding it in place and for subdividing the
space between two or more of said grate bars, the whole being capable of fixing
from the front, substantially as described & shown.
3. The various modifications of coal saving device adapted to fit different sized
grates each taken as a whole, substantially as described and shown.
