PROVISIONAL SPECIFICATION.
Improvements in Kitchen Ranges.
I, JOHN WILLIAM DOBSON of Gordon Street, Sutton Mill near Keighley in
the County of York, Pattern Maker, do hereby declare the nature of this invention
to be as follows, that is to say :-
"
It relates to improvements in kitchen-ranges of the class known as "open-fire
ranges and consists of the formation and application of means whereby these are
or may be converted into closed ranges with the advantages of being able to control
the draught so as to make it follow the courses desired.
In carrying my said invention into effect I form metal coverings to fit over the
cavity for the fire and extend up the usual chimney or flue as far as any other parts
of the iron work at present reach, and in said cavity for the fire I place brickwork
that forms the flue to lead from the bottom back edge of said cavity up against
the covering behind same and forward up the flue leading into the chimney proper.
Thus the draught through the fire is first caused to descend then to ascend,
travelling along until finally it passes up the chimney as described.
In the covering over the fire several openings are made with detachable lids or
coverings so as to allow the placing of pans, kettles or other cooking utensils as
may be desired, and the brickwork flue is so formed that the heat distributing
draught is carried beneath all said openings equally.
Beneath the bottom fire grate a drawer or box for the reception of the ashes,
while doors of the sliding type, are mounted before the front bars.
By placing a damper in the upper part of the flue, while the flues for the pan
and oven on each side thereof are provided with similar contrivances, all the
draught may be allowed to pass up the chimney or regulated to pass beneath the
oven and up its flue or under and up that of the pan.
Dated this 10th day of October 1894.

Improvements in Kitchen Ranges.
I, JOHN WILLIAM DOBSON of Gordon Street, Sutton-Mill, near Keighley in
the County of York, Pattern Maker, 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, that is to say :-
It relates to improvements in kitchen-ranges of the class known as "open-
ranges" and consists of the formation and application of means or parts whereby
these are or may be converted into closed ranges with the advantages of being able
to control the draught so as to make it follow the courses desired.
To enable my said invention to be more readily understood I have hereunto
appended sheets of drawings illustrative thereof, to which by figures and letters
reference is made in the following description.

page_text: Fig. 1 is sectional side elevation (on line A B of Fig. 2) of a kitchen range with
my improved parts applied thereto.
Fig. 2 is a view of same as seen from above and with the upper plate or cover
removed so that the parts beneath might be more clearly seen.
Fig. 3 is a similar view to Fig. 1 (being a section on line E F of Fig. 4) but
shows an arrangement of flues when a "back boiler" is used in connection with my
improved devices.
Fig. 4 is a similar view to Fig. 2 but is illustrative of the arrangement of parts
shown by Fig. 3 and shows the top plate in position.
In carrying my invention into effect I form metal coverings ab to fit over the
cavity c for the fire and extend up the usual flue or chimney as far as any other
parts of the iron work at present reach, and in said cavity c I place a brickwork
partition d that forms the flue e in close proximity with the cavity c by which
means the heat generated by the fire in said cavity cheats the air in the flue'e and
causes it to rise so as to pass up the flue g which leads into the chimney proper.
Thus the draught through the fire is first caused to descend then to ascend
travelling along in the direction indicated by the arrows (Fig. 1), until it finally
passes up the chimney as described the damper h in Figs. 1 and 2 being shown as
closed so that at such time the passage for the draught is shut off in this
direction, while other courses as under the oven or the pan on each side of the
cavity may at this be opened for the passage of the draught and for purposes
well known.
Or when my improved parts are used in connection with a back boiler k then
I have two dampers h' and ' (see Fig. 3, in which both of them are shown as
closing the flue) so that when such boiler has to be heated the damper h may be
opened to allow the draught to follow the course shown by the arrows a, at which
time the damper being closed prevents the draught going in that direction.
In the covering a several openings m m (shown in full lines in the several figures
and also in broken lines Fig. 2) are made with detachable lids or covers so as.to
allow the placing of pans, kettles or other cooking utensils thereon as may be
desired, and the brickwork is so formed that the heat distributing draught is
carried beneath all said openings to an approximately equal degree.
Beneath the bottom grate p is placed a drawer or box s for the reception of the
ashes, while doors t of the well known sliding type, are mounted before the front
bars w.
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 combination in a kitchen range of an upper covering for closing same
and a midfeather formed so as to separate the fire cavity from the flue behind it in
order that the said flue at this part may be as near as possible to said cavity
substantially as shown and described.
2. The combination and arrangerment of the several parts forming my improved
range substantially as specified.
