Improved Means for Utilizing Liquid Fuel in Steam-boiler and
other Furnaces, Stoves, or Fire-places.
I, GEORGE WASHINGTON WHITE, of Waca, in the County of M°Lennan, State of
Texas, United States of America, Gentleman 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 :-
My invention relates to fluid burner fire logs, adapted to be placed in fire chambers
of furnaces, stoves, boilers, brick kilns, fire places and grates; or in any other fire
chamber for warming buildings, generating steam, burning brick and cooking; and
for smelting ores and products thereof; and it consists in the novel construction of
portable fluid burner fire logs, as hereinafter described and specifically claimed.
In the accompanying drawing
Figure 1 is a vertical, longitudinal section of my improved fluid burner fire log,
with the fluid supply and the air induction connections thereof.
Figure 2 is a vertical transverse section of the same, looking toward the supply and
the air induction connections. Figure 3 is a vertical longitudinal section of my fire-
log applied to a locomotive boiler.
Figure 4 is a horizontal section of an ordinary brick kiln with my invention applied
to it, at two ends.
Figure 5 is a longitudinal section on a reduced scale, showing a modification of the
invention.
Figure 6 is a vertical longitudinal section of the fire-log made entirely of fire clay,
and with the perforated oil tube-extension, and the air supply tube left off.
A in the drawings represents a tubular body of the fluid burner fire log, which, in
cross section, may be in the form of a circle, ellipse, ovate, polygon or any other suitable
geometrical figure. This body is constructed with open ends, and with burner, or jet
passages a in its periphery, along nearly its entire length, and partly around or nearly
over its circumference, as circumstances of the use of the log may require. The open
ended body or portion A is closed at its ends by strong, asbestos-packed, flanged metallic
heads A', A²; the flanges a¹, a² of which, overlapping and encircling the ends of the
said body and the edges of the asbestos packing sheets A³, as shown. Through each
of the heads a perforated tube B for conduction and distribution of the supply-fluid, is
inserted, and, on the ends of this tube, screw threads b, b, are cut, and upon these
threaded portions nuts c, e packed with asbestos, as shown, are applied outside the
heads. While the tube B serves as a distributor and conductor of the fluid, it,
with the nuts c c¹, serves also as a means for tying the heads and body A together.
Another perforated tube Chaving screw threads 62, 63, and packed nuts c², c³ at its
ends, is passed through the heads A1, A2, and made to serve as a tie between the
body.A and the heads, same as the tube B, while it serves the purpose of conducting
and distributing air for ensuring combustion at the jet passages of the fluid burner
fire log. The tube B is perforated, preferably, only on top, with one, two or more
rows of jet passages d, while the tube Cis, preferably, perforated all round, or over its
circumference with air inducting passages f; and the tube B is placed in about the
same vertical plane with the tube C, some distance above it, as shown. Within the
fire log-structure, asbestos, in a comminuted or disintegrated condition, is placed, so
as to completely fill the jet passages and chamber formed and enclosed by the body A
and heads A', A', and also surround the fluid supply-tube, and air induction tube, as
illustrated at M in the drawing.. The asbestos, while placed quite compactly in the
fire log, forms numerous capillary passages for the regular and proper flow of the
fluid through it, to the jet passages, and also for the circulation of air for ensuring
combustion of the fluid at said jet-passages. The pipe B is connected with a supply

page_text: pipe from the fluid supply reservoir by means of a coupled vertical pipe B¹, as shown,
and the air conducting and distributing pipe C is connected with a vertical, coupled
air supply pipe C₁, as shown; and the vertical pipes B, C, are provided, respectively,
with a cut off and regulation cock, as indicated at B2C2. At the upper end of the
air supply pipe C, a funnel shaped mouth piece C³, is provided, and this may be fitted
so as to be turned to the wind, as occasion may require. In the drawing, by Figure 4,
I have shown the manner in which a series of fluid burner fire logs may be applied
in the eyes of an ordinary brick kiln, as D, and the series connected by a transverse
pipe B adapted for forming communication with the main supply pipe of the oil
supply reservoir B4, and with a series of vertical, coupled pipes similar to that B'. In
this use of the invention, the air supply pipes will all have a funnel shaped mouth
piece, as C, adapted to be turned to the wind, and when so turned, strong currents of air
will be forced down the pipes into the fire log, and the burning of the oil, at the jet
passages, will be very perfect, and the flames produced will be forced with great
energy away from the jet-passages and whirled, in great burning volumes, into the
arches and admidst the stacks of brick, thus effecting the burning of the brick in a
shorter time, and in a more uniform manner than heretofore with ordinary arrange-
ments for burning.
In Figure 3 of the drawing, I have illustrated the manner in which the invention
may be applied to the fire chamber of a locomotive boiler E; and on the air induction,
or supply pipe C, a funnel shaped mouth piece C³, is provided. With this arrange-
ment the air is forced by the motion of the locomotive down the pipe into the fire log,
and while the combustion at the jet passages is ensured, the whirling of the flames
produced, along the flue or flues of the boiler, is accomplished, and a greater amount
of 'effective heat from a given amount of fuel is secured. In the manufacture of my
improved fluid burner fire logs, I may employ either metal, or fire clay bodies A; but
it is preferable to make the body or portion A of fire clay, or equivalent argillaceous
material, because such material is fire proof, enduring, and not liable to corrosion;
and in connection with this fire clay tube, it is preferable to employ strong cast iron
heads with binding end flanges, and asbestos, or other fire-proof protection-packing at
the joints between the body and the heads and where the nuts are applied on the
pipes, so as to make the joints oil tight; and in order to thus use a clay tube, or
cylinder, and cast metal heads, means for binding the same together must be
provided; and such means are very conveniently and economically secured by my
hereinbefore described, mode of extending the perforated pipes B and C through and
beyond the heads A1, A2, threading said extended ends, and applying nuts thereon for
binding the heads and body together, and at the same time securing the pipes in their
proper positions. By having the heads removable, whether the body portion is made
of clay or metal, the filling of asbestos, or other equivalent fire proof material, can be
conveniently introduced into the chamber of the fire log, and by employing, two fire
proof materials in the construction of the fire log, to wit; fire clay and comminuted
asbestos, great saving is effected, for there will be very little expense after a stove,
grate, furnace, locomotive or kiln has once been equipped with such logs, while a
further greater saving will be effected in cost for fuel consumed, as coal oil, or
petroleum, employed in connection with my logs, is found very effective and
economical for the various uses mentioned, and far preferable to other fuels, the
smoke being consumed, and sparks and cinders avoided. I prefer making the logs
for fire places, stoves and grates, with flattened bottoms, as they maintain their
position better when of that form than when round, but the form is immaterial.
logs may be perforated all round when set above the bottom of the furnace or kiln.
When the logs are small, and used for stoves and grates, the air pipes may be left off
but this would not be a departure from the principle of my invention, as the fire log
formed of a tubular body portion, preferably of fire clay, metal heads, perforated oil
conducting and tie tube, and the asbestos filling, constitute one leading feature; and
the addition thereto of the air-induction. and distributing tube, another important
feature of invention. My portable fire log is adapted for application' to locomotive
brick-kiln and other furnace-chambers, and can be removed for repair, or other

template as a modification of my invention, to cut off the inner extension of the oil
supply tube, and to close the opening in the head through which the end of said
extension passes, and to fill the space which said extension, if used, would occupy, with
asbestos, as illustrated in Figure 5; also to make the fire log entirely of clay, with
one end A solid, and the other end open at a and provided with a closing plug-like
cap A, fastened by a lug a; and also to leave off the air supply tube, as shown in
Figure 6. With this construction the comminuted asbestos, alone, would be the
means for conducting the oil to the jet burner passages; 1, however, prefer to employ
the perforated tie-tube for conducting and distributing the oil and also the perforated
air distributing tube as the same is much the better mode.
