Improvements in Cooking Ranges.
1 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 object of this invention is to provide for the enlargement or reduction of
the fire, as desired, in a more simple and expeditious manner than heretofore; also
to provide for an enlarged roasting surface for cooking ranges; also to provide for
more efficient cleaning of the flues; and my invention consists in the means for
raising and lowering the bottom grate of a cooking range; also of raising or
lowering the vertical bars of the fire, so as to either make a better roasting fire,
in the one case, and also, in the other case, to leave the bottom grate and
fire box unobstructed, for clearing out the ashes, or clearing out the back
boiler flue.
In carrying out this invention, the bottom is movable in any convenient manner,
and at the front it is formed with holes to receive the vertical front bars, which are
attached to a horizontal top bar.
The front is also provided with loops or recesses to receive lugs on the bracket
table, or equivalent piece, on which the table may rest. The front also carries a
pawl which takes into notches on the fret. The pawl is provided with a lever
which projects forward through a lug on the underside of the bracket table, and
by which the pawl may be withdrawn from the notches.
The bottom is raised and lowered by means of the bracket table, which is
also so arranged that it will always be horizontal, whatever may be the position of
the grate.
At the back of the fret is a flange, with holes to receive the vertical bars, which
will be of such a length as to fill up the whole height of the front of the
fire box.
The fire bars are supported by the top bar in suitable sockets attached to the
fire frame.
Instead of a door, I prefer to use a solid fall bar, which rests on the horizontal
top bar, and can be readily removed, so that the top bar can be withdrawn from
its sockets, and raised to the top of the fire frame, on which it rests, so that the
area of the fire front is enlarged to such an extent as to make a good roasting
fire.
The vertical bars, it will be obvious, can be lowered until the top bar rests on
the grate bottom, leaving the fire box open, so that the flues may be reached with
greater facility than heretofore.
Dated this 17th day of January 1895.

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 object of this invention is to provide, first, for the enlargement or reduction
of the fire space of cooking stoves, in a more simple and expeditious manner than
heretofore; secondly, for the enlargement, when desired, of the roasting surface of
cooking ranges; thirdly, for the more efficient cleaning of the flues; and my
invention consists in the means for raising and lowering the bottom grate; also in
the construction and mounting of the vertical bars of the fire, so as to make a
better roasting fire, and to facilitate the removal of those bars, whereby the
bottom grate and fire-box may be readily approached for clearing out the ashes,
or clearing out the back boiler due.
These advantages I secure with a material simplification of the construction,
there being no screws used to fasten any part of the fire fittings, and there being
no hinging at the back of the bottom grate.
In the accompanying drawing,
Fig. 1 is a front elevation of so much of a cooking stove as will serve to explain
the nature of my invention.
Fig. 2 is a transverse section of the same, taken through the fire space in the
line 1-2 of Fig. 1 ; &
Fig. 3 is a sectional plan view taken in the line 3-4 of Figs. 1 & 2.
In these figures, the fire space is closed at its sides by cheeks A A, and its front
is formed by the vertical rectangular fire frame B. C is the bottom grate, which
is capable of being raised & lowered, to contract or enlarge the fire space.
DD are the vertical or front bars, which are capable of being raised or
lowered, to vary the depth of the fire surface, for roasting, and of being readily
removed, when access to the back boiler flue is required. E is the fall bar, aul
F is the bracket table carried by the bottom grate, and capable of ready detachment
therefrom.
G is the plate which closes the fire space at top, and H is the ash-pit under the
bottom grate.
Cast on the inside face of the cheeks, are shoulders a a, which serve to carry the
inner end of the bottom grate, & form fulcra for it to rock upon. The inner en.
of this grate is cast with lumps cc, which overlap the shoulders, and serve to
retain the grate in position, while leaving it free to be raised or lowered from the
front. The front of the grate is cast with two pairs of lugs e¹ & c³. The lugs c
receive a pivot pin which connects a pawl with the grate. This pawl is
designed to engage with teeth or horizontal projections b on the front and centre
of the fire frame B. The use of this pawl is to sustain the grate C at any desired
elevation, which is determined by the rack teeth, or projections, with which it is
brought into contact. This pawl is formed with a shoulder, which is pierced to
receive the end of a cranked hand lever C2, by the turning of which, the pawl
may be readily disengaged from its supporting rack teeth b. The lugs c² of the
bottom grate Care slotted to receive the legs of the bracket table F, and allow
them to rock freely therein. The bracket is cast with struts f', which abut
against vertical ribs on the face of the casting B, & which are stepped to
provide for the table adjusting itself to a horizontal position, irrespective of the
height at which it is held by the rocking grate C. The connection of this table
in the manner described with the grate, enables it to be used as a means for raising
& lowering the grate, to suit the varying requirements of the cook.
The grate in Fig. 2 is indicated at its highest position by dotted lines, and in a

page_text: medium position by drawn lines, & the vertical bars are at their lowest acting
position, the fall bar E being in a vertical position, and closing the space between
the bars & the hot plate G.
Figs. 4 & 5 are front & sectional views corresponding with Figs. 1 & 2, but
representing the movable parts in different positions, the bottom grate being at its
lowest, & the vertical front bars at their highest position. The construction of
the front bars is best seen in the detached view, Fig. 6. They consist of round
rods D, pendent from a cross bar D', the ends of which are rebated at d, to enter
vertical grooves 62 in the cheeks of the fire frame B. The length of the pendent
rods is such as to allow of their passing through elongated slots in the bottom
grate, and always remaining in the row of guide holes 63 formed for them in the
fire-frame B. An incidental advantage of the bottom grate projecting in front
of the vertical bars, is, that when the bottom grate is lifted up, the fire will be
retained thereon, instead of falling forward between the front bars, as heretofore,
in the act of contracting the fire space. On the face of the bar D' a pair of
bolts d is fitted, to enter notches 6 cast in the face of the fire frame B, when the
bars are at their lowest position, as shewn at Fig. 1. When, however, the bars
are raised, as at Fig. 4, these bolts rest upon shoulders 6 at the top of the frame,
and thus serve to maintain the bars at their highest position.
Immediately below these shoulders 6 an opening is made in the front frame to
the vertical grooves 62, for the purpose of allowing the rebated ends d of the
bar D to enter the grooves 2. The length of these grooves is such, that their
bottoms form a support for the front bars, when dropped to their lowest position.
These vertical grooves 6 also serve to support, in a vertical position, the fall
bar E, through pivotal projections e, and stops e¹, which it carries at its opposite
ends, and they also provide for the dropping of the fall bar to a horizontal
position, the pivotal projections then acting in the slots as retaining pins.
From the foregoing explanation it will be understood that my improved cooking
stove possesses the following special merits, independently of simplicity of
construction above adverted to, viz. :-
1. The durability of the front bars is materially increased, owing to there being
nothing to interfere with free expansion & contraction, besides which, being all
attached to the top bar, they are removable by one operation, for either repairs to
fire chamber, or for clearing out ashes from bottom grate or back boiler flue.
2. The necessity for a lifting lever to adjust the rocking grate is avoided, the
loosely attached bracket table being used for that purpose.
3. A perfect roasting fire is obtained when the vertical bars are raised to their
highest position.
4. The stove may be repaired by the insertion of new parts, to replace the old,
without the aid of a skilled workman.
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. The construction and fitting of bottom grate above described, and the loose
connection of the same with the bracket table, as and for the purpose above set
forth, and the means described for maintaining the horizontality of the table at
various elevations of the rocking bottom grate.
2. The construction of vertical bars, as described with reference to Fig. 6, and
the fitting of the same to the stove at varying heights, in the manner and for the
purpose above set forth.
