NATHAN H. COOK, OF ABILENE, TEXAS.
TIRE-H EATER.
SPECIFICATION forming part of Letters Patent No. 454,205, dated June 16, 1891.
Application filed August 30, 1890. Serial No, 363,479. (No model.)To all Wuhonl it 7n cy concern:
Be it known that I, NATHAN H. COOn, a citi-
zen'of the United States, residing at Abilene,
in the county of Taylor and State of Texas,
5 have invented a new and useful Tire-Heater,
of which the following is a specification.
This invention relates to tire-heating fur-
naces; and the object of the invention is to
provide an improved furnace of this charac-
to ter wherein tires of various sizes may be
heated either independently or continuously
and having certain other highly advanta-
geous characteristics, all as hereinafter more
fully described, and as illustrated in the ac-
15 companying drawings, in which-
Figure 1 is a plan view of my improved
tire-heating furnace with the cover removed.
Fig. 2 is a plan view of the cover. Fig. 3 is a
section on the line 3 3 of Fig. 1 with the parts
20 slightly separated. Fig. 4 is a front elevation
of the entire device, showing the same as
mounted upon wheels, whereby it is rendered
portable. Fig. 5 is a perspective detail of one
of the partitions.
25 Referring to the said drawings, the letters
A A' designate, respectively, outer and inner
rings secured upon a floor Z, the whole com-
prising the body of my improved tire-heating
furnace. In the outer ring A at the front
30 thereof is a door G, having a rack a adapted
to be engaged by a finger e, whereby the door
may be sustained at any height and any de-
sired amount of air permitted to pass through
the same to create a draft in the furnace.
35 F is the chimney or exit for the products of
combustion, located diametrically opposite the
door G and preferably provided with a spark-
arrester H of any desired construction.
Between the two rings A A' and rising from
40 the floor Z are secured in any suitable man-
ner a number of partitions D, each having a
deep slot or notch d at its center, and by these
partitions the annular space between the rings
is divided into six compartments more or less.
45 B B are the two halves of a ring, which is
of a size to fit about midway between the outer
and inner rings, and the front and rear ends
of these halves are notched or cut away, as
shown at N.
5o bb are lugs at the opposite sides of the front
and rear partitions D' D2, which rise from
the floor Z to the same height as the othersD, and between these logs the ends of the
half-rings B B may be detachably inserted.
By this meanswhen the half-rings are in place 55
the annular space is divided longitudinally
and the several partitions D rise part way
therein at intervals, for a purpose to appear
hereinafter.
h h are lugs formed upon the inner faces of 6c
the rings A A' and upon both faces of the
half-rings B B at the front, as shown, and on
either side of the front partition D', and I I
are removable gates adapted to be inserted
from above within and between these lugs, as 65
shown in Fig. 1. If desired, the standards J
may be secured to the bottom of the device
and wheels WV mounted upon said standards,
whereby the whole is rendered portable.
E is an annular removable cover whose use 70
is obvious.
With a device constructed as above de-
scribed the tire or tires to be heated are placed
therein, the smaller ones in the inside annular
space and the larger ones in the outside. Shav- 75
ings, chips, and other combustible materials
are placed around them within the device and
ignited and the damper G set so as to admit
the desired amount of draft. If the gates I
are used, as shown in Fig. 1, the draft will be o80
directed into the outer annular space, around
the same, and out of the chimney; but if such
gates should be placed across the outer space
it will be obvious that the draft will be per-
mitted to pass only around the inner space 85
and out of the chimney.
Heretofore partitions similar to those let-
tered D have been used in tire-heating fur-
naces to produce an interrupted flue or pas-
sage-way for the flames or products of coin- 9c
bustion; but I am not aware that the annular
partition B has been used, nor that the same
has been provided with notches h, whereby
the gates I could be employed to close one of
the annular spaces. 95
The use of machines and furnaces of this
.character is too well known to be enlarged
upon here.
What I claim is-
1. In a tire-heating furnace, the combina- roo
tion, with the annular rings A A' and the par-
titions D between and of less height than the
same and provided with notches d in their
bodies, of the ring B, adapted to fit within
