OWEN K. HARRY, OF DALLAS, TEXAS
BAKING, COOKING, AND HEATING FURNACE.
SPECIFICATION forming part of Letters Patent No. 594,993, dated December 7, 1897.
Application filed August 21, 1896. Serial No, 603,500, (No model,)
To all whoim it may concern:
Be it known that I, OWEN K. HARRY, a citi-
zen of the United States, residing at Dallas,
in the county of Dallas and State of Texas,
5 have invented a new and useful Improvement
in Baking, Cooking, and Heating Furnaces,
of which the following is a specification.
The object of my invention is to provide a
light and inexpensive baking, cooking, and
io heating furnace to be used for general house-
hold work, such as heating flat-irons, broiling
meat, baking bread, &c.
My invention consists in the mechanism and
peculiar arrangements of parts, as illustrated
15 in the accompanying drawings and particu-
larly pointed out in the claims.
Figure 1 is a front elevation of the device
complete. Fig. 2is a vertical section through
Fig. 1. Fig. 3 is a section through the lower
20 part of the furnace from A to A, Fig. 1, show-
ing in a plan view the construction of the slid-
ing door of the ash-chamber. Fig. 4 shows a
section through the vertical wall of the fur-
nace, the sliding door, and wires of same
25 from B to B, Fig. 1. Fig. 5 is a section in
a plan view through the baking-oven from C
to C, showing the lower end a of the draft-pipe
extending down to and opening into the bak-
ing-apartment. Fig. 6 is a plan view of the
30 bottom of the baking-oven.
Similar numerals of reference refer to simi-
lar parts throughout the several views.
The numeral 1 is the side walls of a baking-
oven having the top 2 and bottom 3, provided
35 with two wing-shaped flanges 4 4, which are
cut partly loose trom the bottom, with their
ends 5 5 turned outwardly, leaving two ori-
fices 6 6 through the bottom. Extending
through the oven from the front wall to the
4o rear wall, Fig. 5, is a baking-apartment 7, the
front and rear ends being rigidly secured to
the said walls. The baking-apartment is pro-
vided with side walls 8, top 9, (which covers
the baking-apartment from dotted lines 93 to
45 the rear wall 1, leaving a small space in front
between the dotted line 9" and the front wall
of the baking-apartment uncovered,) bottom
10, false bottom 11, and cold-air chamber 12,
provided with air-holes 12" and a door 12b,
50 opening into the baking-apartment.
It will be observed from the sectional draw-
ing, Fig. 2, that in the position occupied by
the baking-apartment in the baking-oven the
hot-air chambers 13 are formed. To the bot-
tom 3 of the baking-oven is rigidly secured a 55
circular flange 14, which will be hereinafter
Below the baking-oven is a detachable fur-
nace 15, having the corrugated side walls 16,
curved rim 17, and curved base 18, concave 6o
grate 19, (with apertures 20 through it,) and
curved flanged edges 21, which fit snugly with-
in one of the corrugations of the side walls.
Below the grate is an ash-chamber 22, having
a bottom 23 with curved flanged edges 24, 65
which also fit neatly in one of the corrugations
of the side walls. The ash-chamber is pro-
vided with a sliding door 25, (its peculiar con-
struction being shown in Figs. 3 and 4,) in
which 16 are the corrugated side walls of the 70
26 are two wires or bands encircling the
outer surface of the walls of the furnace in
such a manner that a corrugated sliding door
is engaged in between the corrugated walls 75
and the wires or bands.
The wall of the furnace is constructed of
metal. The sheet of metal is corrugated and
formed into a cylinder of the proper size.
The bottom is cut out of metal in the form of 8o
a disk, and a flange is formed on the rim or
edge. It is then put in the cylinder and lodged
in one of the corrugations at the desired lo-
cation. Pressure is then applied to the cyl-
inder. This closes the cylinder on the flange 85
of the disk, and enough pressure is applied
to the cylinder to crimp the flange securely
into the corrugation. The two ends forming
the cylinder are then riveted together.
As to the operation of my device a door 90
could be had through the side walls of the
furnace at a point just above the ash-door
leading into the fire-box, through which a fire
could be made on the grate. In the arrange-
ment shown in the drawings it will necessi- 95
tate the baking-oven being detached from the
furnace, so that a fire can be kindled in the
fire-box, which when done the oven is placed
on the furnace, the flange 14 extending down-
wardly into the fire-box 27 in such a manner 100
that the draft-holes 28 in the upper end of the
furnace are cut off. The heat arising from
the fire-box is deflected by the wing-shaped
flanges of the bottom of the baking-oven,
Here’s what’s next.
