PROVISIONAL SPECIFICATION.
Improvements in Self-generating Gas-burners for Burning Oils.
1, GEORGE SYLVESTER GRIMSTON, of "Claremont," Glenluce Road, Westcombe
Park, in the County of Kent, Engineer, do hereby declare the nature of this
invention to be as follows:--
In my Specification No. 16636 of 1888 I have described a form of lamp in which
a jet of steam directed through the vapour generated on the surface of oil in a pan or
basin creates an upward current of oil vapour and steam along with air drawn in
laterally, producing when kindled a long and brilliant flame.
My present invention relates to improvements in lamps of this kind. Instead of
feeding the oil from a reservoir to the pan of the lamp in the manner described in
my former Specification, by an action which is liable to derangement when the
reservoir becomes heated by proximity to the flame, I employ a valve governed by the
position of a float in a chamber interposed between the reservoir and the pan, so that
the valve being opened by the descent and closed by the ascent of the float, the level
of the oil in the pan is kept nearly constant.
Instead of generating the steam for the jet in a pipe coil surrounding the base of
the flame as described in my former Specification I employ a boiler in the form of a
cylindrical annulus surrounding the base of the flame, and in order to guard this
boiler from excessive heat I line its internal wall with refractory material, employing
for that purpose a pipe which may be of fireclay or ceramic ware. I also provide a
shield at the side of the oil reservoir to protect it from the heat of the flame. In
other respects the construction and action of the apparatus are substantially the
same as described in any former Specification above referred to.

COMPLETE SPECIFICATION.
Improvements in Self-generating Gas-burners for Burning Oils.
I, GEORGE SYLVESTER GRIMSTON, of "Claremont," Glenluce Road, Westcombe
Park, in the County of Kent, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
In my Specification No. 16636 of 1888 I have described a form of lamp in which
a jet of steam directed through the vapour generated on the surface of oil in a pan
or basin creates an upward current of oil vapour and steam along with air drawn in
laterally, producing when kindled a long and brilliant flame.
My present invention relates to improvements in lamps of this kind. Instead of
feeding the oil from a reservoir to the pan of the lamp in the manner described in

that the valve being opened by the descent and closed by the ascent of the float, the

other respects the construction and action of the apparatus are substantially the same
as described in my former Specification above referred to.
Fig. 1. of the accompanying drawings is a vertical section of the oil reservoir and
burner arranged according to my present invention.
Figs. 2 and 3 shew modified forms of the boiler and feed valve.
In all these figures like letters of reference are employed to designate corresponding
parts.
A is the oil reservoir from which a passage a governed by a screw plug a¹ leads to
the valve 6 which, as shewn in Fig. 1 is formed by a groove of a plunger, as shewn in
Fig. 2 is in the form of a throttle valve, and as shewn in Fig. 3 is in. the form of a
check valve, subject in all to the action of the float B which closes the valve as it
rises. Beyond the valve the passage c leads to the burner basin or cup C, having in
its centre the conoidal air inlet c governed by the valve c². The boiler D, as shewn
in Fig. 1 is a cylindrical annulus surrounding the flame tube; as shewn in Fig. 2 it
is a conical annulus, and as shewn in Fig. 3 it is a cylindrical annulus having its
outer wall corrugated to allow for unequal expansion and contraction of the parts.
The boiler D is fed by the pipe d with water from the pressure tank described in
my previous Specification. The steam generated in D passes by the pipe e to the
central nozzle E whence it issues in a jet drawing with it oil vapour and air which
being kindled produce a flame, the lower part of which heats the boiler D the oil and
the air inlets.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In oil burners of the kind described in the Specification No. 16636 of 1888, the
use of a valve operated by a float for determining the level of the oil in the basin of
the burner, substantially as described.
2. In oil burners such as are above referred to, the use of an annular boiler
surrounding the base of the flame for generating steam for the central jet, substantially
as described.
