CHARLES JEAN KOCII, OF AUSTIN, TEXAS.
FIRE-CLAY CHARCOAL-FURNACE.
SPECIFICATION forming part of Letters Patent No. 715,392, dated December 9, 1902.
Application filed May 24, 1901. Serial No, 61,742, (No model.)To all whoim it imcy concern:
Be it known that I, CHARLES JEAN KocH, a
citizen of the United States, residing at Aus-
tin, in the countyof Travis and State of Texas,
5 have invented a new and useful Improvement
in Furnaces, of which the following is a speci-
fication.
The invention relates to furnaces, and more
particularly to that class made of refractory
Jo material constructed to permit of its being
fed with fuel without removing the kettle,
boiler, or other utensil placed upon the same.
The object of the invention is to provide a
furnace of this character which shall be sim-
15 ple of construction, durable in use, cornpara-
tively inexpensive of production, and effi-
cient in action.
With this and other objects in view the
invention consists of certain novel features
20 of construction, combination, and arrange-
ment of parts, which will be hereinafter more
fully described, and particularly pointed out
in the appended claims. .
In the accompanying drawings, Figure 1 is
25 a perspective view of my improved furnace,
and Fig. 2 is a top plan view.
1 denotes the body of the furnace, which is
made of refractory material, such as fire-clay,
provided at its upper end, above the grate 2,
30 with an opening 3, the edges of which are em-
braced by a channel-iron frame 5.
6 denotes a door hinged to one side of the
channel-iron frame, and 7 denotes a fasten-
ing means for holding the door in closed po-
35 sition.
The upper peripheral edge portion of the
furnace is provide with lugs or projections 8,
on which a vessel rests, so that the products
of combustion may pass out from the body
40 of the furnace between the bottom of the ves-
sel and the peripheral edge portion of the
said furnace.
I wish it to be understood that the frame 6
is connected to the edges of the opening 3by means of a downwardly-sliding action of 45
the same, and I use no fastening means other
than a clamping action of the frame with the
edges of the opening.
It is evident that when the boiler, pan, or
cooking utensil is placed upon the top of the 5o
furnace said furnace may be fed with fuel
through the door-opening without removing
the cooking utensils.
This furnace is particularly designed as a
charcoal-burning furnace, although it should 55
be understood that other kinds of material
may be used.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
ent, is- 6o
1. A furnace of the class described having
a doorway in its upper side, the upper side
of the doorway being open, a door-frame slid-
ably fitted from above in said doorway and
having its sides channeled exteriorly to form 65
flanges which overlap the inner and outer
sides of the furnace contiguous to the doorway,
and a door, mounted in the said frame and
removable from the furnace therewith, said
door when closed lying within the frame and 7C
in the plane of the side of the furnace in
which the doorway is formed, substantially
as described.
2. A furnace of the class described having
a doorway in its upper side, the upper side 75
of the doorway being open, a door-frame slid-
ably fitted from above in said doorway and
having its sides channeled exteriorly to form
flanges which overlap the inner and outer
sides of the furnace, contiguous to the door- 8o
way, and a door hung to the said frame, sub-
stantially as described.
In testimony whereof I have affixed my sig-
nature in the presence of two witnesses.
CHARLES JEAN KOCII.
