PROVISIONAL SPECIFICATION.
Improvements in Self-generating Petroleum Vapour Burners.
I JOHN HUTCHENS GARTRELL Dentist 47 Chapel Street Penzance Cornwall
do hereby declare the nature of this invention to be as follows:-
My invention relates to self-generating vapour burners for heating purposes similar
to that described in a Complete Specification filed by me in application for a Patent
No. 14,804 A.D. 1893 and illustrated by Figs. 5, 6 and 8 of the drawing.
My present improvements consist in continuing the tube through the middle of
the diamond and from the centre of this cross tube, casting a square tube to convey
the vapour generated in the diamond shaped tubes to the two jets carried by a cross
piece at right angles to the square tube. These jets play through an adjustable
double tube carried upon the square tube.
The vapour from the jets also pass through the apertures formed by the tubes of
the diamond.

COMPLETE SPECIFICATION.
Improvements in Self-generating Petroleum Vapour Burners.
I, JOHN HUTCHENS GARTRELL, of 47 Chapel Street, Penzance, in the County of
Cornwall, Surgeon Dentist, 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 self-generating vapour burners for heating purposes similar
to that described in a Complete Specification filed by me in application for a Patent
No. 14804, A.D. 1893, and illustrated by Figs. 5, 6, and 8, of the drawing.
My present improvements consist in continuing the tube through the middle of
the diamond and from the centre of this cross tube casting a square tube to convey
the vapour generated in the diamond-shaped tubes to the two jets carried by a cross
piece at right angles to the square tube. These jets play through an adjustable
double tube carried upon the square tube.
The vapour from the jets pass through the apertures formed by the tubes of the
diamond.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and figures
marked thereon.
Fig. 1, is a side elevation of the burner and stand.
Fig. 2, is a front elevation of the burner and stand.
Fig. 3, is a continuation of the nipple a.
Fig. 4, is a plan of the top of the burner.

In carrying my invention into practice I provide a tube b in the middle of the
diamond c and from the centre of the tube b I cast a square tube d to convey the vapour
generated in the diamond (c) shaped tubes to the two jets e carried by a cross piece ƒ

page_text: at right angles to the square tube d. These jets e play through an adjustable double
tube carried upon
I
the square tube d.
The vapour from the jets e also pass through the apertures h formed by the tubes of
the diamond c.
In working this burner a preliminary heat is given to it by the Bunsen gas
burner a¹ or a dish may be substituted for the Bunsen burner to hold spirit, the
flame from which will heat the petroleum burner sufficiently to vapourize the
petroleum as it passes through the burner. The adjustable tubes are also slid
back close to the jets, so that the vapour escaping from the jets under
pressure burns with a blue flame around the square tube as well as outside
the burner and may be used in this position for such purposes as brazing.
For heating a crucible or muffle fireclay furnace, the tubes g are to begin with
adjusted close to the jets e and when the muffle gets red hot they are slid upon the
square tube d close to the diamond e the blue flame will then disappear around the
square tube and the vapour burn in the furnace only with increased intensity and
power. The jets are made by drilling through them about a three-sixteenth inch
hole and brazing in the hole a disc of very thin nickel plate through which is made a
fine hole about No. 76 Stubbs' gauge, a jet made in this way is not so liable to choke
in working.
The burner may be also used for lighting purposes by making the holes in the
nickel plate of jets a little larger, the petroleum vapour will then burn with a
white flame.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In self-generating petroleum vapour burners, the combination of the middle
tube through the diamond c and from the centre of the tube b casting a square
tube d to convey the vapour generated in the diamond shaped tubes to the two jets e
carried by the cross piece at right angles to the square tube d and the adjustable
double tube g carried upon the square tube d, substantially as herein described and
according to the accompanying drawings.
2. In self-generating petroleum vapour burners, the combination of the various
parts described in the specification and illustrated in the accompanying drawings.
