COMPLETE SPECIFICATION.
Improvements in or relating to Kitchen Ranges.
We, THOMAS MANN of 9 Church Street, Bricklayer, and JOHN MANN of 8 Merrick
Street, Bricklayer, both of Bolton in the County of Lancaster, do hereby declare the
nature of our said invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
:-
This invention refers to improvements in or relating to kitchen ranges and consists
in means for enlarging or increasing the cooking power of the same.
Fig. 1 is a front elevation of a kitchen range constructed on our improved principle.
Fig. 2 is a sectional elevation through line AB-Fig.3 is a sectional elevation through
line EF Fig. 4 is a sectional plan through line CD1-Fig. 5 is a sectional plan
through line GH-Fig. 6 is a sectional plan through line K-Fig. 7 is a part
sectional elevation through line M' N', and Fig. 8 is a sectional elevation through
line O¹ P¹.
In all the figures the same letters are employed to indicate corresponding parts.
A is the ordinary oven; B the oven door; C the ordinary fire-bars; D the swivel
or falling bars, and E the hot hob.
In the space or cavity above the oven A and on
the top plate F we construct the oven G provided with the sliding door H. The
door His mounted in the slides or grooves I on the plate and upper plate J,
which are provided with stops to prevent the door H being slid therefrom when
opening the oven. The door H can he provided with hinges similar to the oven
door B, in which case it will be a swinging door. When the oven door H is made
to swing on hinges the slides or grooves I are dispensed with. The oven G is
heated by heat from the oven A underneath; the bottom of the former being the
top plate of the flue. K over the oven A. The smoke or heat from the fire place L
passes in the usual manner under the oven A and up the back or side flues M and N to
the chamber K above the same and up the side flue P to the chimney X.
The flues M and N are constructed as shown in Figs. 5 and 6 to ensure of the heat
and smoke being evenly distributed over the top of the oven A in its passage to the
side flue P. The side flue P is constructed of metallic plates, and is provided with the
swivel damper to regulate the draught according to the requirements of the ovens.
The portion of the side flue P above the swivel damper Q is fitted with the scraper R
attached to the rod S extending to the front side, from whence it can be moved to
and fro to clear the sides of soot. The rod S-is fitted with the knob T to operate the
same. The scraper plate R is constructed with the projections U, which rest and slide
on the upper end of the side flue P to support the same.
The ordinary hot-hob E is heated by smoke and heat from the fire-place L in the
usual manner, from whence they are carried up the flue or passage V behind the back
plate W to the chimney X. The flue or passage V is fitted with the swivel damper Y
and handle Z. On the plate F we fix or mount the extra hot-hob Y' with the passage Wi
to convey smoke and heat from the flue or passage V under the hot-hob Y and to the
side flue X leading to the chimney X. The side flue X is constructed of metallic
plates, and provided with the swivel damper V¹ to regulate tho draught. The portion
of the side flue X' above the swivel damper V₁ is fitted with the scraper U³ attached
to the rod Textending to the front side, from whence it can be moved to and fro to
clear the sides of soot. The rod T₁ is fitted with the knob S to operate the same.
The scraper U is constructed with the projections P' which rest and slide on the upper
end of the side flue X' to support the same. When it is desired to use the hot-hob E alone
the swivel damper Y in the Hue or passage V must be opened and the swivel damper Vi
in the side flue X' closed. In case it is desired to use the hot-hob Y¹ the swivel
damper Y inust be closed and the swivel damper V₁ opened. The side flues P and X'
are provided with the openings M2 and covers N2 to allow of soot being cleared from

page_text: the bottom of same.
The hot-hob is provided with the opening E2 and covers G³,
the latter being removed when cooking is being performed thereon.
Another part of this invention relates to an improved method of mounting the catch
for securing in position the swivelling or falling bars D when raised to make a deep
fire-place. To the side plate employed for supporting the fire-bars we mount the
catch in line with the side barsj of the swivelling or falling bars D as shown in
Figs. 6 and 8. The catch is pivoted to the side plate by the pink, being held
in position by the pin fixed in the side plate. When the swivelling or falling
bars are raised the front edge operates on the projection b on the catch hand lifts
the same sufficiently high to allow the front side or edge to pass the said projection,
which, immediately the bars D are in a vertical position, drops down and secures the
same. The catch is provided with the projecting end g to enable the same to be
operated by hand. The chief advantage of this improved catch is that it can be easily
removed or replaced without taking the range to pieces which is the case with those at
present in use.
It will be seen that our improvements when applied to a kitchen range will con-
siderably increase the cooking power of the same both as regards baking, roasting, and
boiling.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. In a kitchen range the use of the oven G disposed above the ordinary oven A,
and the means for conveying smoke and heat from the chamber K above the oven A to
the chimney X consisting of the side flue P, substantially as described.
2. In a kitchen range the use of the hot-hob Y¹ disposed on the plate Fabove the
ordinary hot-hob E, and the means for conveying smoke and heat from the chamber W
under the same to the chimney X consisting of the side flue X' and the damper V₁,
substantially as described.
3. In combination with the side flues P and X' the use of the scrapers R and U¹ and
the means for operating the same for the purpose specified substantially as described.
4. The use of the catch h with the projection and handle g pivoted to the frame f
and in line with the side or edge of the swivelling or falling bars D, substantially as
described.
