We, JAMES THOMAS PRICE, Tailor, Ton Pentre, Rhondda and HENRY
ATTWOOD GEORGE, Chemist, 188 Ystrad Road Pentre Rhondda both in Wales,
do hereby declare the nature of this invention to be as follows:-
This invention consists in combining with a lamp a non supporter of combustion
either in a fluid, solid or gaseous state such as carbonic acid gas or the like and
which may either wholly or partially surround the reservoir containing the oil or
other illuminant, or may be contained in a separate receptacle so that in the event
of the lamp being tipped over, broken or taking fire, the non supporter of
combustion will be liberated so as to extinguish the flame or fire. A suitable
valve may if desired, be employed to liberate the carbonic acid gas or the like in
the event of the lamp taking fire, and this valve may be so connected as to enable
the carbonic acid gas to be liberated at any desired part of the lamp.

Improvement in Lamps.
We, JAMES THOMAS PRICE, Tailor, Ton Pentre, Rhondda and HENRY
ATTWOOD GEORGE, Chemist, 188 Ystrad Road Pentre, Rhondda both in Wales,
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 consists in combining with a lamp a non-supporter of combustion
either in a fluid, solid or gaseous state such as carbonic acid gas or the like and
which may either wholly or partially surround the reservoir containing the oil or
other illuminant, or may be contained in a separate receptacle so that in the event
of the lamp being tipped over, broken, or taking fire, the non supporter of
combustion will be liberated so as to extinguish the flame or fire. A suitable valve
may if desired be employed to liberate the carbonic acid gas or the like in the
event of the lamp taking fire; and this valve may be so constructed as to enable
the carbonic acid gas to be liberated at any desired part of the lamp.
In order that our invention may be fully understood we will now refer to the
annexed drawing in which :-
Figure 1. is a side elevation of a lamp constructed according to my invention.
Figure 2. section to enlarged scale of the valve for liberating the non supporter
of combustion when required.
For purposes of illustration we have shown our invention applied to an oil lamp
in which 6, is the inner reservoir or receptacle which contains the oil or illuminant
D

page_text: which is charged into same by any convenient aperture for this purpose. a is an
outer reservoir or receptacle which encloses the reservoir or receptacle b, and is of
such a size as to leave a space c, between the two reservoirs which may be of any
suitable material such as glass or metal. This space is charged with the non-
supporter of combustion, such as carbonic acid gas, under suitable pressure through
an aperture which is afterwards sealed such as at e; fis a plug having the screw
thread upon same which engages in a screw thread in the outer casing or
reservoir.
The joint between the inner & outer reservoirs and the plug is constructed so as
to prevent leakage or escape of the non-supporter of combustion until required.
The dotted lines h indicate an aperture or channel formed in the plug which
terminates at the side of the plug f, at i and is closed by the surface of the inner
reservoir as shewn in Figure 2. When the plug f is unscrewed, the aperture i is
brought into communication with the space c and the non-supporter of combustion
such as carbonic acid gas will then pass through the channel and over the
surface of the oil and thus extinguish any flame or combustion which may be
taking place. It will be readily seen that the shape and position of the respective
reservoirs may be varied without departing from the principle of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The combined construction and arrangement of the various parts substantially
as described and shown.
2. In lamps in combination, a receptacle or chamber carrying a non supporter
of combustion such as carbonic acid gas; a valve for liberating such non-supporter
of combustion when required for the purpose of extinguishing the combustion of
the illuminant.
