Improvements in or relating to Cooking Stoves and Ranges.
1, HOWARD MATRAVERS. ASHLEY, of The Eoundry; Ferrybridge, in the
County of York, Engineer and Lronfounder, 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 hy..the following statement :→
In my Specification No. 9122 of 1890, I have described the construction of a
cooking stove with two fires, the one above the other; and according to my
present invention I can convert any existing cooking stove, if the fire-basket bo
deep enough, into a two-fire stove, in such a manner that either the top or bottom
fire can be used separately, or both can be used at the same time, with all the
advantages resulting from my previous invention above referred to, and also those
resulting from an invention commonly known as the "Eagle," or lifting fire. To
effect this, I provide a bottom grate of auy suitable dimensions and section, with a
wedge-shaped, stop at each side, underneath the grate, and about as far back from
the front edge of it as the thickness of the bar of the range to which it has to be
attached. I also make the bottom grate with a sort of shank or stunted handle in
the middle of its front edge, to which I attach a suitable slide or sliding sleeve,
provided with a rack and pawl, or a slot with bolt and out, so as to readily adjust
the slide or sleeve on the shank, to compensato for the variation in the width of
different range hars: I then provide a self-locking lever handle, which insert
into a locking slot in the shank, by which to lift the movable bottom-grate into
and out of position.
Fig. of the accompanying drawings is a longitudinal section of the arrange-
ment in which the bolt, nut, slot and slide are used, with parts of fire-range,
movable bottom-grate, and lever handle broken off.
Fig. 2 is a plan of the same.
Figs. 3 and 4 aro respectively a longitudinal section and a plan of the arrange-
ment in which the rack, sliding sleeve, and pawl are employed.
The full lines shew the sleeve pushed home, against the bar and locked in
position by the papland the lever or bandle at rest, shewing how the grate has
been lifted into position, and the dotted lines shew the pawl thrown back, the
sleeve liberated and drawn back from the bar, and the lever just being inserted
ready to lift up and withdraw the movable grate from-between the bars.
Fig. 5 is a diagrammatic section of a fire-place of a cooking stove to which the
grate has been attached, and Fig. 6 is an alternative section of grate where it is
not convenient to insert a flat grate between the bars. In this arrangement a
dished grate is dropped into the fire basket and is provided with means of being
lifted in and out of position.
The same letters refer to the corresponding parts in each of the drawings. A is
the frame work, and B. are the front bars of an ordinary fire-grate. C the
removable bottom-grate. D wedge shaped stops attached to it. E shank pro-
jecting from the front of grate C. F movable slide with bolt and nut as shewn in
Figs. 1 and 2 or sliding sleeve with rack and pawl as shewn in Figs. 3 and 4.
Gadjustable handle or lever, H point of contact between slide or sleeve and bar
of range.
I Fig. 6 hooked bar, from the middle of which projects the shank E by which it
can be introduced into the fire basket or removed therefrom.

page_text: The operation of the apparatus may be understood by referring to Fig. 5,
a indicates the top flue for passage of products of combustion when the fire is
closed by the top plate, bindicates the bottom flue to supply heat under the oven,
as in a Yorkshire rauge. When a deep fire is not required the movable grate C is
raised by the handle G, and slid out and then in between any two of the front
bars according to the desired depth of fuel until the stops D drop within the lower
of the two bars.
The slide or sleeve F is then moved close up to the upper bar and secured by
tightening the nut or dropping the pawl into the rack.

The handle G, being theu withdrawn the fire can be laid on the grate, which is
so firmly held as to be capable of bearing any ordinary weight of cooking utensils.
When the botton flue 6 has to be used the handle G is again inserted and the
grate C is raised until the stops D can pass over the lower bar. The grate C
being then drawn forward, the fire falls on to the fixed or ordinary bottom
grated which can then supply heat to the lower flue b. Part of the fire
on C can thus be dropped and part retained on C, so that both fires may work
together.
When the front bars B are vertical or otherwise shaped so as not to admit of the
grate C sliding between them, I employ as shewn in Fig. 6 a dished grate C which
can be hooked on the upper bar, this grate having also stops D under it to steady.
it in position. It can be canted by a lever such as G applied to the shank Ę so as
to disengage the hooks I and lift the grate C.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed; I declare that what I
'claim is:
1. In combination with a cooking stove or range a movable grate having under
it wedge stops and in front of it a shank adapted to receive a lever handle and
provided with an adjustable slide or sleeve, substantially as and for the purposes
herein set forth.
2. In combination with the removable grate above referred to, a slotted slide
with bolt and nut, substantially as described with reference to Figs. I and 2.
3. In combination with the movable grate above referred to having rack teeth
on its shank, a sleeve and pendent pawl, substantially as described with reference
to Figs. 3 and 4.
4. The removable dished grate provided with shauk,, hooks and stops,
substantially as described with, reference to Fig. 6.
