An Improved Coal-saving Appliance for Domestic and other
Fire Places.
J, WILLIAM HARVEY, of 40 China Lane, Piccadilly, Manchester, in the County
of Lancaster, Paper Meichaut, do hereby declare the nature of this invention to
be as follows.
My invention relates to an improved coal saving appliance for domestic and other
fire places and the object of my improvements is to economise fuel and to improve
combustion.
In cari ying out my invention I use a plate preferably of cast iron which is placed
upon the bottom of the grate, this plate is slotted and has preferably a number of
projections cast upon its upper surface; for a grate with a circular front 1
may cast
with the slotted plate a number of vertical bars connected or not by a bar at the
top; these vertical bars are formed to correspond with the circular front of the
grate and stand within the front bais.
Where the grate has a flat or nearly a flat front the slotted plate is made without
any vertical bais but it can be used with an ordinary front coal saving grid which
may be detached from, or attached to, the plate.
The slotted plate is made somewhat smaller than the grate and a lug or knob may
be cast or secured to the plate, which lug projects in front of the grate; a pokor
or special handle may be applied to the lug, or otherwise to the plate, so that by
moving the handle the slotted plate is caused to move to and fio in the grate. By
this means the coal is shifted on the projections on which it rests, and the ashes
pass away through the slots, in this manner the combustion of the fuel is improved
and a certain portion of fuel is saved

An Improved Coal-saving Appliance for Domestic and other
Fire Places.
WILLIAM HARVEY 40 China Lane Manchester in the County of Lancaster
Paper Merchant 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 relates to an improved coal saving appliance for domestic and
other fire-places; the objects being to economise fuel and improve combustion.
In carrying my improvements into effect I use a grid or slotted plate which may
be used either soparately or in combination with a number of vertical bars, tho said
vertical bars being connected together and when applying the same to a new fire-grate
I may form the slotted plate and vertical bars together in which case the usual
horizontal fire-bars may bo dispensed with. My invention will readily be under-
stood by reference to the annexed sheet of drawings, of which Fig. 1 is a front

page_text: elevation and Fig. 2 a cross section, which shew the slotted plate with pin and
vertical bars in their relative positions when placed in a fire-giate, and Figures 3
and 4 are plan views of the same respectively. Figure 5 is a plan view of a
grate which propose to use in connection with the above plate and bars and
hereafter more particularly referred to. In Figs. 1, 2, & 3 a. is the slotted on
combustion plate the bars b. of same being preferably taper in section as indicated
atc. and having projections d. on the upper surfaces thereof either pyramidal in
shape as shewn or of other suitable form. The lower edge of the plate is well
rounded so that it may ride more freely within the grate when moved. e is a lng
formed with the plate and provided with a slot el for the purpose of agitating the
plate, or I may make a hole, in lieu of the lug, for the same pui pose. ff. show tho
vertical baie which are connected together by the horizontal bar g. the said
vertical bars having suitably shaped projections h. which point inwards towards
the fire. I also form a slot in one of the vertical bars to obtain a lateral movement
by using a handle I also provide a hook 1. (see Fig. 2) formed so as to clasp one
of the usual fue bars and one of the vertical bars of the "coal saver" thereby
retaining the latter man upright position and preventing came from falling
inwards. It will now be clear that by moving the slotted grid a." and the
vertical bais "f" from side to side and in a partially rotary direction as indicated
by the arrows in Figs. 1 & 2. the ashes which have collected at the bottom of the
grate may be cleared away and the fire stured by being in contact with the
projections "." and "." thereby obtaining free air space and promoting
combustion and preventing the fire from being broken up and the coal from
falling out on to the hearth-thus economising fuel. Figure 5 shews a plan viow
of a specially shaped fiame "." the bars of same being fewer and the openings
wider than usual. It will be seen that by drawing forward the slotted plate
(which is to be used in combination) the fire grate can be more readily cleared.
In this a rangement I also provide a guide "" at each side of the fire place and
when substituting the vertical bars or "conl saver" in lieu of the usual fire bars
the former is provided with projecting ends as shown by dotted lines "in." Fig. 1.
these projecting ends m. fitting into the guides "1" will retain the coal saver in its
proper position, still allowing it to be moved sideways. I may make an additional
connecting bar at the top, the ends of said bar or bars projecting into the guides "”
for the purpose aforesaid.
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 18.-
1. A horizontal grid and vertical bars either separately or combined, having
projections as described and provision for agitating said plate and bars as heroin-
before described and illustrated by the accompanying sheet of drawings.
2. A special form of frame or grate botton having oxtra large openings for the
purpose of more readily emptying the grate, to be used in connection with the
hereinbefore described improvements.
3. The use of the said combustion plato and coal saving appliance and then
application to new and existing fire grates, separately or combined and for the
purposes herein described.
