Improvements relating to Vapor-burners and to Apparatus for the
Supply of Oil thereto.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 :-
The invention consists, first in a burner which is intended for heating purposes,
wherein the vapor of oil or the vapor of oil mixed with steam is caused to mingle
with an incoming current of air, and in which the mixed air and oil vapor or mixed
air, oil vapor and steam being ignited yields an intensely hot and smokeless blue
flame; and, second, in a tank or receptacle of special construction for holding a
supply of oil for said burner.
In the accompanying drawings, Fig. 1 is a vertical section of one form of the
aforesaid burner on the line X X of Fig. 2. Fig. 2 is a transverse section on the .
line Y Y of Fig. 1. Fig. 3 is an elevation of the oil tank. Figs. 4 and 5 show said
burner as modified in construction so as to use steam in addition to mixed oil vapor
and air, these views being in vertical section.
Similar letters of reference indicate corresponding parts.
A is a vaporizing chamber preferably circular in form and provided with a down-
wardly extending tube B. The chamber A and tube B may be made if desired in a
single casting. The tube B is threaded at its lower extremity to receive a threaded
central tubular projection C. From said projection C, extend radially hollow arms D
closed at their outer extremities and there terminating in supporting feet E. Entering
the projection C is a smaller tube F which extends up through the tube Band into the
chamber A, as shown. Said tube F communicates directly with the hollow arms D.
In the upper sides of arms D are orifices G.
His a cylindrical casing resting upon shoulders formed on the feet E and extending
up to the lower side of the chamber A. At the upper part of said casing is an

page_text: orifice I extending around said casing which if desired may be closed by a screen J of
wire gauze.
Just below said orifice I, and extending around the casing H is an
annular trough K. Lis a tube which passes through the casing H and communicates
with the tube B and with the oil tank, Fig. 3.
The operation of the above described burner is as follows, The oil being admitted
through the tube L rises up through the tube B and forms a thin layer covering the
bottom of the vaporizing chamber A. A small quantity of naphtha, alcohol or a wick
saturated with oil or any other easily combustible material is placed in the trough K
and ignited. The chamber A is thus heated and the vaporization of the oil therein
started.
The oil vapor as it is produced descends through the tube F and entering the hollow
arm D escapes into the casing H through the orifices G in said arms. Air mean-
while enters said casing through the large intervals M between said arms. The mixed
air and vapor rising up through the casing H escapes through the orifice I and are
ignited outside of said orifice. The heat thus produced greatly raises the tempera-
ture of chamber A, and so hastens the volatilization of the oil until the latter becomes
vaporized about as fast as it enters. The flame then completely surrounds the
periphery of chamber A, which in fact spreads it and should be substantially smokeless
and intensely hot.
Referring now particularly to Fig. 3, N is the oil tank or receptacle, O is the
cover, Pa spigot or air vent in said cover and L the pipe for conducting the oil to
the burner.
The device as here shown consists of four metal corner posts R connected by two
series of transverse bars S. T and by longitudinal bars U so as to form a frame. To
this frame is secured wire gauze which may be conveniently made in the form of a
long strip, which is carried first, longitudinally over the frame to form a horizontal
partition V, then vertically over two bars S to form a vertical partition W, then
longitudinally again to form another horizontal partition V', again vertically over two
bars T to form another vertical partition W', and so on. The frame with the gauze
attached is placed in the tank N and may be secured therein if desired. The tank is
then filled with oil in the usual way.
When the tank is agitated as by the vibrations of a locomotive or other vehicle,
or by the rolling of a vessel, vertical displacements of the oil are prevented by the
horizontal partitions V, V₁, &c. and lateral displacements by the vertical parti-
tions W, W, &c. In this way the oil is prevented from moving about in the tank
and hence it flows uniformly out through the pipe L.
.
The invention is not limited to the precise construction of tank here shown inasmuch
as the same may be varied. The perforated partitions may be placed all vertically or
all horizontally or otherwise be differently arranged.
Referring now to the modifications of the invention exhibited in Figs. 4 and 5;
the vaporizing chamber A¹ is provided with an upwardly extending recess G'. Water
enters by the duct B¹ and flows over the bottom of the chamber. C¹ is the oil duct.
In Fig. 4. the ducts C and B₁ are shown as semi-tubular in form, the delivery
orifice D' of the duct C¹ being above the delivery orifice E¹ of the duct B'. In Fig. 5.
the ducts C and B¹ are tubular in form and arranged concentrically with the gas
tube H¹. In the construction shown in Fig. 4. the chamber A' is first heated by a
little oil ignited in the trough F'. This trough is omitted in the device shown in
Fig. 5, as the simple application of a flame anywhere to the outside of chamber A¹
will determine the starting of the gas flow. The mingled steam and oil vapor passing
into the recess G¹ proceeds through the tube H into the arms I', whence it escapes by
the openings J' and finally is ignited at the orifice K¹.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated
to me by my foreign Correspondent I declare that what I claim is :-
1. In combination with a closed vaporizing chamber, an oil conduit and a gas
conduit both in communication with said chamber, a hollow casing arranged below said

page_text: chamber communicating at or near its lower portion with said gas conduit, and with
the atmosphere and having at or near its upper portion an escape orifice for said gas
substantially as described.
2. In combination with a closed vaporizing chamber, an oil conduit, a water conduit
and a gas conduit, all communicating with said chamber, a hollow casing arranged
below said chamber communicating at or near its lower portion with said gas conduit
and with the atmosphere and provided at or near its upper portion with an escape
orifice for said gas, substantially as described.
3. An oil tank containing reticulated or perforated partitions arranged substantially
as hereinbefore set forth.
