An Improved Burner for Liquid Fuel.
We, CARL ADOLPH SAHLSTRÖM and ALECK FRASER. HILL, of Nos. 36
& 37, St. Ermin's Mansions, Westminster, in the County of Middlesex, Engineers,
do hereby declare the nature of this invention to be as follows:-
1. The burner consists of three tubes placed one within the other in such a
manner that they are concentric in cross section.
2. The inner tube is for the fuel. It is provided with a detachable, tapering
nozzle of brass or other material; and, at the rear with a long screw for adjusting
purposes; and has suitable perforations to give ingress to the fuel. The end may
be provided with a hand wheel; and the pipe may be closed with a screw plug,
both removable for cleaning purposes.
3. The second pipe is for steam, and encloses the before mentioned fuel pipe;
maintaining same in suitable position by means of a perforated diaphragm. It,
also, is provided with a detachable tapering nozzle, the interior angle of which is
not quite parallel to the exterior angle of the nozzle of the fuel pipe, thus admitting
the finest possible adjustment. Towards the rear, this pipe is furnished with a
steam inlet; and a chamber, with fuel inlet is constructed in the butt. The fuel
pipe passes through this chamber, and the ingress perforations, mentioned in
section 2, are so arranged that there is always one or more within the chamber.
A portion of this steam pipe has an exterior raised screw thread by which it is
attached to, and regulated within the third pipe.
4. The third or exterior pipe is for air. It has an open mouth, and a flanged or
threaded inlet.
5. Each pipe may be furnished with washers and nuts for tightening up and
fixing in position when they have been adjusted.

COMPLETE SPECIFICATION.
An Improved Burner for Liquid Fuel.
We, CARL ADOLPII SAHLSTRÖM, now of 10, Colville Gardens, Bayswater, and
ALECK FRASER HILL, of Nos. 36 and 37, St. Ermin's Mansions, Westminster, in
the County of Middlesex, Engineers, 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 burner consists of three tubes placed one within the other in such a manner
that they are concentric in cross section, and our invention will be best understood
by describing same with reference to the accompanying drawings.
Figure 1 is a longitudinal vertical section of a burner for liquid fuel constructed
according to our invention and Figure 2 is a half vertical cross section of same
through the line X Y of Figure 1.
The inner tube A is for the fuel, it is provided with a detachable, tapering
nozzle B of brass or other material, and at the rear with a long screw C for
adjusting purposes; and has suitable perforations D to give ingress to the fuel.
The end may be provided with a hand wheel E and the pipe may be closed with a
screw plug both removable for cleaning purposes.
The second pipe G is for steam, and encloses the before mentioned fuel pipe A
the latter being maintained in central position by means of a perforated diaphragm

page_text: or guide G. This steam pipe G is provided with a detachable tapering nozzle J
the interior angle of which latter is not quite parallel to the exterior angle of the
nozzle B of the fuel pipe, thus admitting the finest possible adjustment. Towards
the rear of the steam pipe G, this pipe is furnished with a steam inlet K; and a
chamber K with fuel inlet K2 is formed in the butt.
The fuel pipe A passes through this fuel chamber and the ingress perforations D
before referred to are so arranged that there is always one or more within the said
chamber K. A portion of the steam pipe G has an exterior raised screw thread L
by which it is attached to, and regulated within the third pipe M and this third or
exterior pipe is for air. It has an open mouth, and a flanged or threaded inlet N
Figure 2.
Each pipe may be furnished with washers and nuts for tightening up and fixing
in position when they have been adjusted.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:
First In liquid fuel burners, the combination with an inner fuel tube A, a
surrounding steam pipe G and an outer air pipe M all arranged concentrically, of
the screwed part C, the hand wheel and plug E, and apertures D, the chamber K
with entrance K2 together with the steam entrance K, and the air inlet N all
substantially as and for the purposes herein described with reference to the accom-
panying drawings.
Second: The improved burners for liquid fuel composed of three tubes or
pipes A G M arranged concentrically one within the other for the admission and
conveyance of fuel, steam, and air the said pipes being fitted with nozzles adjusting
screws, perforations for fuel and other appliances all constructed arranged and
acting substantially as described with reference to the accompanying drawings.
