PROVISIONAL SPECIFICATION.
Improvements in Kitchen Ranges and in Plate Warming Apparatus
connected therewith.
I BENJAMIN HARLOW of King Edward Street, Macclesfield, in the County of
Chester, Engineer, do hereby declare the nature of my said invention to be as
follows
This invention relates first, to improvements in the construction of ovens of
kitchen ranges whereby the same can be more rapidly and efficiently heated than
heretofore and consists in employing an additional flue across and near the top of
the oven and formed in one piece therewith or as an attachment and removable
for cleaning and repair. This additional flue passes from the flue on the fireplace
side of the oven to the outer side flue of the oven, the inlet to this flue being
lower in the fire-place than the opening leading to the usual flue which passes over
the oven.
This additional flue is the full length or depth of the oven, a space
being left at the front and back and so that the entire metal flue is available as
heat radiating surface within the oven.
I sometimes employ an additional flue of similar character at the bottom of the
oven having its inlet from the outer side flue and its exit at the back and so
provide additional heating surface. The flues may be corrugated if desired.
Secondly my invention relates to means of adjusting the width and area of the
fire-grate of a kitchen range from back to front for the purpose of economising
fuel and consists in forming the front bars of the range movable and sliding in
grooves or channels or bars formed on or in the sides of the grate so that the
capacity of the fire-box for fuel may be increased or diminished at pleasure by
moving the front bars in or out. To facilitate the adjustment I prefer to attach
the grate bars to the front bars and provide accomodation under the boiler for
the grate bars to retire as the capacity of the fire-box is diminished by the pushing
in of the front bars.
I may employ a rack and pinion or a screw and lever to move the front bars
under the hand of the attendant.
Thirdly my invention relates to the rack employed in kitchen ranges for heating
plates, dishes ete, and consists in substituting pipes for the solid bars hitherto
employed these pipes terminating at each end in a cast iron hollow pedestal the
bottom of which is connected by a branch pipe to the interior of the circulating
hot water boiler. In this manner I circulate hot. water through the pipes and
form a more efficient heating surface for the purpose or I enclose the said pipes
to form a hot closet.

COMPLETE SPECIFICATION.
Improvements in Kitchen Ranges and in Plate Warming Apparatus
connected therewith.
I BENJAMIN HARLOW of King Edward Street Macclesfield in the County of
Chester, Engineer 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 :-
This invention relates,
First. To improvements in the construction of ovens of kitchen ranges, whereby

page_text: the same can he more rapidly and efficiently heated than heretofore and consists
in employing additional flues across and near the top and bottom of the ovens
Fig. 1 and Fig. 2 A. A. and formed in one piece therewith, or as an attachment
and removable for cleaning and repairs. These additional flues A. A. pass from
the flue on the fireplace side of the oven, to the outer-side flue of the oven. The
inlet to these flues being lower in the fire-place than the opening leading to the
usual flue which. passes over the oven.
These additional flues A. A. are the full length of the oven, a space being left
at the front and back, and' so that the entire metal flues are available as heat
radiating surface within the oven, and are made in steel wrought iron or cast iron.
I sometimes employ additional flues of similar character at the bottom and top
of the oven, having inlet from the outer side flue, and its exit at the back and so
'provide additional heating surface. The flues A. A. may be corrugated if
desired and work on grooves or slides, and act as smoke consumers.
Secondly. My invention relates to the rack employed in kitchen ranges for
heating plates, dishes &c. Fig. 3. E. and consists in substituting pipes E. for the
solid bars hitherto employed, these pipes terminating at each end in a wrought or
cast iron hollow bracket G. G, the bottom of which is connected by a branch
pipe to the circulating hot water boiler F.
In this manner I circulate hot water through the pipes E, and form a most
efficient heating surface for the purpose, or I can enclose the said pipes, and form
a hot closet and oven, the pipes E are of copper, wrought or cast iron.
Thirdly. My invention relates to means of adjusting the width and area of the
firegrate, Fig. 4. and Fig. 5, H. H.-of a kitchen range from back to front, for
the purpose of economising fuel and consists in forming the front bars of the
range H. H. moveable and sliding in grooves or channels or bars, Fig. 3 and
Fig. 6. C. C. formed on or in the sides of the grate, so that the capacity of the
fire-box for fuel may be increased or diminished at pleasure by moving the front
bars H. H. in or out. To facilitate the adjustment, I prefer to attach the grate
bars J. J. to the front bars H. H. and provide accomodation under the boiler F.
for the grate-bars to retire, as the capacity of the firebox is diminished by the
pushing in of the fire bars H. H, the boiler F is supported by a strong iron plate.
I may employ a rack and pinion, or a screw and lever, to move the more the
front bars H. H., under the hand of the attendant.
Plate 1. Fig. 1. 2, illustrates the movable oven-radiators or flues A. A. which
increase the heating power of an oven also consume the smoke and work on grooves
or slides.
Plate 1 Fig. 3. illustrates the plate rack, with hollow hars or pipes E. connected
from the hollow brackets G. G. to the range boiler F. with flow and return pipes
for the circulation of hot water.
Fig. 3. F. is the range boiler fixed on iron plate K.
Fig. 3. D. space under the boiler for bottom of sliding bars H. H. to retire.
Fig. 3. B. B. B. B. illustrates the angles and curves of the ovens, which are
formed with castings, these castings also form the ovens, internal oven flues, smoke
flues, and soot boxes, fitted together with straight plates of steel or iron.
Plate 2. Fig. 4. shews sliding bars H. moved in, to reduce area of fire box.
Plate 2. Fig. 5. shews sliding bars level with the front of the range.
Plate 2. Fig. 6., shews the grooves or bars C. C. formed on the sides of the
grate for the fire bars H. H. to slide on, in or out, to reduce area of the fire box.
Having now particularly described the nature of my invention, and in what
manner the same is to be performed, I declare what I claim is :-
First. The arrangement of internal oven flues, as radiators, and smoke con-
sumers, as an attachment or formed in one piece and removeable, for cleaning and
repairs, working in grooves, or slides, fixed to each side of the oven, made in steel,
wrought or cast iron.
Second, The substituting pipes in copper wrought or cast iron for circulating

page_text: hot water through, instead of solid iron bars as hitherto used in kitchen ranges, as
plate warmers. These pipes also formed as hot closet and ovens, and connected
by flow and return pipes, to the range boiler.
Third. The adjustable fire bars, to reduce the width and area of the fire box of
a kitchen range from back to front, by pushing the fire bars in or out. The
bottom bars of the fire-grate retire under the boiler in a space provided, the boiler
being supported on a strong iron plate, under this plate the space is left for the
bottom bars of the grate to retire.
Fourth. The substituting castings to form the angles and curves of ovens,
internal oven flues, smoke flues and soot boxes fitted together with plates of steel
or iron.
