Improvements relating to Open-fire Cooking Ranges.
I, 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:-
In open-fire cooking ranges, it is usual to have what is termed a bonnet," or
smoke preventer, and these "bonnets have hitherto been either fast or moveable.
The moveable bonnet has been either moveable in a vertical sense, or what is
termed a "draw out" bonnet, both of which have disadvantages which it is now
desired to overcome.
The object, then, of the present invention, is to produce a bonnet which will
retain the advantages, of these two kinds of bonnet without the disadvantages,
and the invention consists in so combining these forms of bonnet, as to attain the
object in view.
In carrying out this invention, I provide a plate to form the front of the flue,
which is so mounted in a frame or in the covings as to be capable of being raised
and lowered as required.
This plate may be loose, or attached at its bottom edge in any convenient manner
to a draw-out bonnet. The lower edge of this bonnet takes onto sets of pins
inserted in the side of the frame or in the covings so that it may be supported at
any height desired, and curved grooves are made in the sides of the bonnet into
which certain of the sets of pins enter, when the bonnet is closed in any other
than its highest position.
Vertical grooves may also be made in the sides of the bonnet, so that the
bonnet may be raised when closed.
By these means, the bonnet can be raised and lowered, and opened or .closed,
more or less, as desired, thereby greatly increasing the efficiency of the bonnet.
Dated this 12th day of July 1898.

Improvements relating to Open-fire Cooking Ranges.
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:-
In open-fire cooking ranges, it is usual to have what is termed a "bonnet" or
Sineke preventer, to guide the smoke to the chimney, and these bonnets have
hitherto been either fixed or movable. The fixed bonnet is secured. in position
when the range is set. The movable bonnet has however been arranged in two
ways, that is to say, either always extended, and movable in a vertical sense or

draw-out
movable only in a horizontal sense, the latter form being known as a
bonnet. Both of these forms of bonnet have disadvantages which it is now
desired to overcome.
;
The object then of the present invention is to produce a bonnet which will
retain the advantages, without the disadvantages, of these two kinds of bonnet,
and the invention consists in so combining these forms of movable bonnet as to
attain the object in view.
In the accompanying drawings,
Figure
is a front view of so much of an open-fire range as is required to
illustrate my invention.
Figure 2 is a vertical section on the line 1-2, and
Figure 3 a similar section on the line 3-4, both of Fig. 1.
Figure 4 is a sectional plan on the line 5-6 of Fig. 1, and
Figure 5 shews, in side view, the bonnet detached.
A is the fire place, B is the hot plate, C are the covings, and D is the chimney.
Mounted on the hot plate, and secured to the covings (or it may form part of the
covings), is a frame E, to which is attached at the top, and across the front, a
plate or panel F, to close up any space that may be left by lowering a sliding
panel, hereafter described.
In the sides of this frame. E, grooves G are formed to receive the sliding
panel H, and also the bonnet I. The panel H slides behind the panel F when the
bonnet is raised, and may be provided with a counterweight or counterweights.
On either side of the frame E, and just in rear of the groove G, three, four, or
more studs or stops K are placed, on which the sides of the bonnet I are to rest
when the bonnet is extended.
The bounet I consists of a front plate or panel, having, at its upper end, trunnions
or pivot pins L, and segmental side pieces M. These side pieces M are formed with
curved grooves or recesses N (the radius being struck from the pivots L), to
receive the studs or stops K, under certain conditions.
The side pieces may be also be provided with a straight groove or recess P, just
in rear of, and parallel with, the front, to allow of the bonnet being raised when
closed up, notwithstanding the stops K, and at the back lower edge a stop 0 is
provided.
The panel H is first placed in position, and is held up until the bonnet is fitted
into its place, with its pivots or trunnions in the grooves G. The panel H is then
let down, so that it rests on the top of the bonnet I.
The height of the bonnet above the fire is regulated by the position of the
stops K, on which the bottom edges of the sides of the honnet rest, the pivots or
trunnions of the bonnet being slidden upwards in the grooves G, with the
panel H, to the height desired.
In the drawings, four different heights above the fire are provided for.
The stops regulate the amount of movement outwards of the bonnet, by
coming into contact with the studs K, on which the sides M of the bonnet are
resting for the time being. The curved recesses N receive the pairs of studs K
above those on which the bonnet is resting when the "draw out" movement
takes place.
In Figure 3, the closed position of the bonnet is shewn in dotted lines.
It will be obvious that the term "open-fire" ranges will include close-fire ranges,
when they are used, as is often the case, with open fires, by removing the top
plate. In such a case, the close-fire range is, to all intents and purposes, an open-
fire range, and the invention is applicable thereto.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1 The cantation to on onen fire rasime of a bonnet capable of both a vertical

page_text: movement and a horizontal swinging or "draw out" movement in a frame or
the covings, as and for the purpose set forth.
2. The combination with a bonnet capable of both a vertical movement and a
horizontal swinging or "draw-out" movement in a frame or the covings, of a
sliding panel, as shewn and described.
3. The combination with a bonnet capable of both a vertical movement and a
horizontal swinging or "draw-out" movement in a frame or the covings, of a
sliding panel and a fixed panel across the front of the frame, as set forth.
4. The arrangement and construction of movable bonnet appliance as herein
shewn and described.
