PROVISIONAL SPECIFICATION.
Improvements in Self-generating Gas or Vapour Lamps.
I, GEORGE ROSE, of 105 Bishop Street, Glasgow, Engineer, do hereby declare
the nature of this invention to be as follows :-
This invention relates to self-generating gas or vapour lamps and it has for its
object to improve their construction.
In carrying our my invention, under one arrangement, I make the vapour or gas
generating chamber of, preferably, cylindrical shape and so fit it upon the stand
tube of the lamp that the longitudinal axis of the cylinder is preferably at right
angles to the supply pipe from the oil tank or reservoir.
The burners, of which there may be two, are, preferably, arranged on each side
of the vapour chamber in such manner that the flame or flames play horizontally
against the sides or ends of said chamber and keep it constantly heated. The
burners and connections may be made the same as those usually fitted on a
Halliday" lamp.
The oil tank or reservoir may be fitted below the burners and the oil be forced
up by means of a suitable pump or in other manner. The pump, with small lamps,
may consist of a rubber or like ball having a non-return valve fitted in or in
connection with it.
In some cases the oil may be supplied by gravitation from a reservoir fitted
above or along side the burner.
The lamp may be made with several burners arranged, or not, in a cluster if
so desired.
The lamp may have a suitable handle or handles and be portable.
In some cases the vaporizing chamber may be made of a tube or tubes arranged
in the form of a square, ring, or otherwise, and a spreader plate or plates may be
cast or fitted in or on the chamber against which the flame, or flames, impinges.
The chamber may be filled or partially filled with asbestos or like material.
Under a modification the chamber may be made with jet orifices at each side and
the flames be made to play up against two spreader plates, arranged, one at each
side of the chamber.
Dated this 6th day of April 1893.
COMPLETE SPECIFICATION.
Improvements in Self-generating Gas or Vapour Lamps.
I, GEORGE ROSE of 105 Bishop Street, Glasgow, 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:→
This invention relates to self-generating gas or vapour lamps and it has for its
object to improve their construction.
In carrying out my invention, under one arrangement, I make the vapour or gas
generating chamber of, preferably, cylindrical shape and so fit it upon the stand
tube of the lamp that the longitudinal axis of the cylinder is preferably at right
angles to the supply pipe from the oil tank or reservoir.
The burners, of which there may be two, are, preferably, arranged on each side

The oil tank or reservoir may be fitted below the burners and the oil be forced
up by means of a suitable pump or in other well known manner. The pump with
small lamps may consist of a rubber or like ball having a non-return valve fitted
in or in connection with it. In some cases the oil may be supplied by gravitation
from a reservoir fitted above or alongside the burner.
The lamp may be made with several burners arranged or not, in a cluster if so
desired.
The lamp may have a suitable handle or handles and be portable.
In some cases the vaporizing chamber may be made of.a tube or tubes arranged
in the form of a square ring or otherwise and a spreader plate or plates may be
cast or fitted in or on the chamber against which the flame or flames impinge.
The chamber may be filled or partially filled with asbestos or like material.
Under a modification the chamber may be made with jet orifices at each side and
the flames be made to play up against two spreader plates arranged one at each side
of the chamber.
And in order that my said invention, may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front elevation of a small portable upright lamp constructed in
accordance with my invention.
Fig. 2 is a section to an enlarged scale of the head of the lamp.
Fig. 3 is a part section of a portable heater.
Fig. 4 is a plan of the modified construction of vaporizing chamber shown at
Fig. 3.
Fig. 5 is a cross section of the chamber and spreader plate Fig. 4.
Fig. 6 is a side view of the valve fittings of the heater Fig. 3.
Fig. 7 shows a slightly altered burner.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same or similar parts.
a is the oil tank which has fitted in it the stand tube b upon the top of which is
screwed the lamp head c. The hollow cylindrical vaporizing chamber d (see
Fig. 2) has cast in one with it the pipes d', d³, d³, d. The parts do and do are or
may be solid. d' are cleaning plugs. d³, d are the burner nipples from which the
oil gas or vapour generated in the chamber d, after passing through the_con-
nections d', d, d³, d', issues in two jets, one at each side of the chamber d. When
the jets are ignited the flames beat up against the sides of the chamber and are
deflected through the passage ways left between the radial ribs e.
This duplex
flame heats the chamber d to a high degree, and, whilst giving a brilliant light,
ensures a thorough vaporization of the oil.
f is an oil supply regulating valve. 9 is the usual air pump. h is a socket for
the reception of the stand tube b screwed into the tank a.
If desired, as shown at Fig. 2, asbestos may be placed in the chamber d.
The portable heater shown at Fig. 3, consists of the oil tank a, with its fittings,
and a bent tube b' on the lower end of which the head c is fitted. The head, in
this case, may consist, as shown, of a vaporizing chamber formed of a rectangular
arrangement of tubes i having a spreader plate j cast in one with or secured to
them. The parts are otherwise similar to the head Fig. 2 except that the mixing
chambers have not the radial ribs e. As will be seen the head is enclosed in a
cylindrical casing 1, having a lid & cross bars for supporting a plumbers
melting pot, soldering bolt or other article to be heated. m is a small sliding
door.
The valve f, may as shown in Fig. 6 have a branch f¹ in which another valves
is fitted. Said branch f¹ has a vertical branch f into which the stand tube of a
lamp may be fitted. With this arrangement the heater may be either used as a

page_text: lamp or a heater or as both. The valve regulates the oil supply for the heater
whilst the valve regulates the oil supply for the lamp.
The casing 1 may be hinged or jointed to the tank a as shown in dotted lines, at r,
or be secured thereto by straps as shown in full lines.
In Fig. 7 the burner is shown as provided with a needle valve y.
If desired the lamp head Fig. 1 may be used instead of the heater head Fig. 3 or
vice versa.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is :-
1. The construction of lamp head with its vaporizing chamber and burners,
substantially as hereinbefore described and shown at Figs. 1 and 2 of the drawings
annexed.
2. The modified construction of head or burner, substantially as hereinbefore
described and shown at Figs. 3, 4, and 5, of the drawings annexed.
3. The construction of portable heater, substantially as hereinbefore described
and shown at Fig. 3 of the drawings annexed.
Dated this 6th day of January 1894.
