PROVISIONAL SPECIFICATION.
Improvements in Heating Lamps applicable to Hydro-carbon Engines,
and Apparatus therefor.
I, JOSEPH GROVE of 74 Strahan Road Grove Road, London, E., Engineer
do hereby declare the nature of this invention to be as follows :-
:-
My invention has for its object the combustion of heavy petroleum for the
purpose of producing a flame of intense calorific energy with means for auto-
matically supplying maintaining and regulating the desired pressure whereby the
said flame is kept burning without pulsating or flickering, and consists of a tube
bent at its upper end to any desired angle or curve into which is fitted a small
burner or burners above which is arranged a deflecting or spraying device; the
other end of the said tube is affixed to and projects into a reservoir containing
the necessary supply of petroleum and compressed air. In communication with
the reservoir is a small pump which supplies the air drawn from the atmosphere
to the reservoir; the piston of the pump is actuated automatically by the
compression & explosion of the charge in the motor cylinder which is placed in
communication with the pump piston by a pipe; any desired degree of compression
can be obtained by regulating the quantity of air drawn into the pump by means
of a small cock or equivalent device or by restricting the communication between
the motor cylinder and the pump.

Improvements in Heating Lamps applicable to Hydro-carbon Engines,
and Apparatus therefor.
I, Joseph GROVE of 74 Straham Road, Grove Road, Bow, London, E.,
Engineer, 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 object of my invention is the combustion of heavy petroleum so as to
produce a flame of intense calorific energy as well as the provision of means for
automatically supplying, maintaining and regulating the necessary pressure at the
burner whereby the said flame is kept burning without pulsating or flickering.
Figure 1 is a sectional side elevation, taken on the line 1-1 of Figure 2, of the
cylinder cover, vaporizer, burners and burner chamber.
Figure 2 is an end elevation corresponding with Figure 1.
Figure 3 is a side elevation, partly in section, of the petroleum supply pump, air
and petroleum mixture reservoir and their connections.
Figure 4 is a side elevation of the air supply pump, part of the air and petroleum
mixture reservoir and their connections.
Figure 5 is a sectional elevation taken on the line 5-5 of Figure 4.
a is the petroleum supply pump. It may be of any suitable construction and be
driven in any convenient way. It delivers through the pipe into the reservoir c;
the pipe being fitted with a suitable non-return valve. The function of the
reservoir is to contain petroleum and a volume of compressed air, the resilience
of the latter being the agent relied on to deliver the oil at a constant pressure

page_text: through the pipe which supplies the burners. c¹ is a safety valve which is set to
open when the compression in the reservoir has reached a certain point.
The desired compression in the reservoir is established and maintained by a
special air pump which is worked by the engine. d is the cylinder of this pump
and d¹ its piston. The latter is a loose one and is driven in one direction by the
compressed mixture in the engine cylinder acting upon it through the pipe e ; and
in the opposite direction, by the pressure of the outer air which acts upon it
through the pipe el. The latter is fitted with a suitable non-return which opens
inwards. is the air delivery pipe to the reservoir c. It, too, is fitted with a
suitable nou-return valve.
g is the oil supply pipe from the reservoir c to the burners. h is the ignition
tube, and the chamber of the heating lamp. The supply pipe g terminates in
the conjoined barrels of two stop cocks g', g' adapted to respectively control
communication between the said pipe and the two pipes ², h³ of the heating lamp.
These pipes are led in a horizontal direction into the lamp chamber towards the
ignition chamber of the engine, i, and then bent downwards. j, j are the lamp
burners, one on the end of each pipe. j¹ is a device for spreading or deflecting the
flames as they issue from the lamp burners. k is a hit and miss slide adapted to
provide for the ventilating of the burner chamber.
I is a by-pass to be used only when the engine is being started. It is provided
with a stop cock by which it is controlled. This stop cock is opened before the
engine is started. There will then be a clear way for the combustible mixture to
flow along from the engine cylinder through the reservoir c to the burners.
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. The herein before described improvement in heating lamps.
2. The herein before described apparatus for maintaining a constant pressure in
the pipe supplying combustible to the heating lamp.
3. The combination of the hereinbefore described improvement in heating lamps
with the hereinbefore described apparatus for maintaining a constant pressure in
the pipe supplying combustible to the said lamp.
