PROVISIONAL SPECIFICATION:
An Improved Burner for Crude-oil or other Liquid Fuel.
I WILLIAM WILSON HORN of the firm of Horn & Son of 151 Strand in the
County of Middlesex, Patent Agent do hereby declare the nature of this invention
(a communication to me from Alfred Bradley and Theodore Willi both of Dayton
Montgomery County State of Ohio, United States of America, Inventors) to be as
follows:-
-
This my invention relates to an improved burner for crude oil or other liquid fuel
and it consists in the construction and arrangement of the several parts hereinafter
described.
The burner is in form of a cup-shape and has a central conical or tapering recess
through the lower part thereof.
Within the said recess is fitted the lower portion of a solid metallic vaporizer, a
small space being left at the bottom of the recess to form an oil chamber.
The said vaporizer consists of a solid metallic plug the lower part being turned
or otherwise fitted in the conical recess as before mentioned and the upper part
carried above the floor or bottom surface of the burner the said upper portion being
reduced in size and forming a shoulder at its junction with the lower portion..
The lower portion of the vaporizer is formed with an annular recess said annular
recess communicating by means of suitable ducts or channels with the floor or
lower surface of the burner and similar ducts lead from the said annular recess to
the oil chamber beneath the vaporizer.
The supply pipe is attached and opens into the said oil chamber.

An Improved Burner for Crude-oil or other Liquid Fuel.
I WILLIAM WILSON HORN of the firm of Horn & Son of 151 Strand.
in the County of Middlesex Patent Agent do hereby declare the nature of this
invention (a communication to me from Alfred Bradley and Theodore Willi both of
Dayton in the County of Montgomery State of Ohio United States of America
Inventors) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement.:-
In order that my invention may be readily understood reference is made to the
accompanying drawings in which
Figure 1 is a vertical sectional view of my improved burner with the vaporizer
in position.

Fig. 3 a cross section of the vaporizer through the line ..

My invention relates to improvements in appliances for vaporizing and burning
crude oils, and its object is to provide a simple inexpensive safe and efficient device
whereby liquid fuel of every description may be thoroughly consumed and the heat
readily utilized for any desired purpose. The invention consists of a movable
Pri d]

page_text: apparatus in which the oil is first subjected to close contact with a vaporizer by
which it is quickly converted into-vapour, which is superheated as it ascends to the
burner in attenuated jets, in which form it rapidly combines with the oxygen of the
atmosphere and produces a flame of intense' heat
The peculiarsconstruction of, the device will be readily understood by reference
to the accompanying drawings, in which. A. designates the body of the burner,
having a central subconical recess to receive the vaporizer B which is closely
fitted therein.
The said vaporizer consists of a solid metallic plug having the lower portionb of
the shape of a frustum of a cone to fit into the recess a and form therewith.the oil-
chamber H: The said lower portion has surrounding it the annular recess, D.
which when the vaporizer. is in place: forms a heating chamber for the oil. The
upper part of the vaporizer projects above the burner A and serves still-further.
to spread and heat the ascending burning, vaporized oil. One or more small segments
are-cut from the vaporizer between the recess or chamber Dánd the lower end of the
vaporizer to permit the oil in limited quantity to pass into the annular recess D. These
cut-away-parts form ducts C when the vaporize is in place to permit the oil to ascend
from the chamber H to the recess D. A suitable number of vapour ducts Eare
formed by simply grinding or cutting small segments from the body of the vaporizer
between the recess Diand the shoulder. of the vaporizer; which shoulder is flush
with the adjoining part of the floor of the burner A. The supply of oil is regulated
by a valve G. in the pipe leading from the oil-reservoir, which pipe Ghas its upper
end threaded and fitted into an opening in the burner. and communicates with the
chamber-H:..
The operation of the device is easily described. When the valve is opened, the oil
ascends into the cup of, the burner where it is ignited. The vaporizer and burner
soon become 'heated and the oil being diffused in a thin filin on the surface thereof
becomes rapidly converted into vapour which is super-heated in its passage in the
form of thin jets to the burner. Being, thus doubly prepared, it instantly, combines
with the air and is thoroughly consumed. The oil ascends from the pipe g to the
chamber H and thence through the ducts C'to the annular recess Dwhere it is
heated both by the vaporizer and burner. Thence it ascends in films through the
ducts E and there ignites and passes up the surface of the part of the vaporizer
surrounding the same. If desired, a concentrator (see Fig. 5) may be employed to
confine the heat to narrow limits, or the contrary effect may be produced by placing
a cap over the burner, so formed as to disperse the heat: In practice it is found
that this process effectually utilizes the-various constituents of roils, and no provision
is required to dispose of residue..
If extraneous matter should be introduced with the oil it will be retained in the
recess. H below the vaporizer, and any accumulation may be easily removed.
The various advantages of this device are worthy of special notice. It can be
made of all sizes.at a trifling, expense. Any required number may be placed in a
series and used to advantage, in the fire box of a stove, or in a furnace, and any one.
or more may be disconnected by simply turning a valve. By employing a flexible
supply pipe the burners may be easily moved from place to place' and 'made
available whenever it becomes desirable or expedient to vary the direction"and"
application of the 'heat:
Having now particularly described and ascertained the nature off my said inven-
tion and in what manners the same is to be performed.I declare, that what I
claim is.
1. The combination with the cup shaped burner provided with 'a central conical
or tapering recess in its floor and the oil supply pipe-opening into the bottom of the
sáid recess of a solid inetallic vaporizer having its lower or base part fitted into said
recess in such a manner that an oil chamber is formed below it'therein, and provided
with a surrounding annular recess in said 'lower part to form a heating chamber
with the burner, and suitable ducts extending from the oil-chamber below the

page_text: burner to the said recess and from the recess to the floor of the burner substantially
as specified.
2. The combination, with the burner A. having the recess a and the supply pipe g
opening into the bottom of the said recess, of the solid metallic vaporizer B having
the lower portion provided with the surrounding annular recess D and the sets of
ducts C and E the upper portion extending above the floor of the burner and
forming the shoulder with the lower portion, substantially as specified.
