JOHN I-I. JOHNSON AND JAMES MORAN, OF ORANGE, TEXAS.
FURNACE.
SPECIFICATION forming part of Letters Patent No. 485,762, dated November 8,1892.
Application filed March 22, 1892. Serial No. 425,897. (No model.)To all wTonom it may concern:
Be it known that we, JOHN H. JoHNSON and
JAMES MORAN, citizens of the United States,
residing at Orange, in the county of Orange
5 and State of Texas, have invented a new and
useful Furnace, of which the following is a
specification.
This invention relates to furnaces; and it
has for its object to provide an improved fur-
to nace especially adapted to be located at the
side of a kiln or drying-house, which furnace
shallbeso constructed as to be simple, durable,
and inexpensive, and the parts of which may
be readily put together or separated, as may
15 be desired.
To this end it is the primary object of this
invention to provide important improvements
over our former patent, No. 462,354, dated No-
vember 3, 1891.
20 With these and many other objects in view,
which will readily appear as the nature of the
invention is better understood, the same con-
sists in the novel construction, combination,
and arrangement of parts hereinafter more
25 fully described, illustrated, and claimed.
In the accompanying drawings, Figure 1 is
a perspective view of a furnace constructed
in accordance with our invention. Fig. 2 is
a verticallongitudinal sectional view. Fig. 3
30 is a vertical transverse sectional view.
Referring to the accompanying drawings,
A represents the casing of our improved fur-
nace, which casing is composed of a semicir-
cular series of sets of rectangular metal plates
35 B. The plates forming the top and a portion
of the side of the casing are curved, so that
when all of the plates are clamped together
the said furnace-casing will be approximately
semicircular in cross-section. Each of the
40 rectangular plates B are provided with the
encircling flanges C, which surround all four
sides thereof and meet the adjacent flanges
of the adjacent plates of each series and set,
all of said flanges thereby closely fitting each
45 other to form a continuous and unbroken cas-
ing, which is firmly held together by passing
bolts D through all of the meeting flanges.
It will be readily seen by this construction
that any particular portion of the casing may
50 be removed without disturbing the other parts
thereof for the purpose of repairs, &c., and
also that the entire casing can be dissembled,if so desired. Interposed between the meet-
ing flanges of all the plates is the asbestus
packing E, which not only forms a tight joint, 55
but serves as a cushion to allow for the ex-
pansion and contraction of the various plates.
The meeting flanges of the end plates of the
casing form continuous semicircular end
flanges, to which are secured the front and 6o
rear end plates F and G, respectively, from
which rear end plate projects the annularly-
flanged collar H, while the front end plate is
provided with the doors I and J, which com-
municate with the fire-box and ash-pit, re- 65
spectively. Theinterior of the casing accom-
modates the ordinary grate K, separating the
ash-pit from the fire-box.
Securely and detachably connected to the
flanged collar II is the sectional flue L. The 7o
said flue L, which is connected to said collar
in rear of the furnace, extends rearwardly
a short distance, thence laterally, as at L',
and then forwardly, as at L, to the stack L3,
which extends upwardly at the front end of 75
the flue and in a line with the front end of
the furnace. The said flue comprises re-
versely-arranged pairs of semicircular sec-
tions or plates M, which sections are provided
with the straight horizontal flanges N along 80o
the sides thereof, while their ends are also
provided with the semicircular flanges O.
The said semicircular sections or plates com-
prising the flue are placed one above the
other and having the several flanges thereof 85
closely in contact, which flanges are securely,
yet detachably, bolted together by means of
the bolts P, and also have interposed there-
between the asbestus packing and cushion Q
for the same purpose as the similar packing 90
and cushion between the flanges of the cas-
ing-plates. The lower semicircular plates or
sections of the flue rest upon aseries of suit-
ably-located supports R, which thus support
the lower sections of the flue and allow any 95
one or all of the upper semicircular sections
to be removed and replaced when desired
without a disturbance of the other parts, thus
securing an important advantage over ordi-
nary furnace-flues. Too
The ends of the flue portions L' and L2, re-
spectively, have their open ends terminate in
circular flanges formed by the meeting semi-
circular flanges of the upper and lower flue
