Improvements in Apparatus for Extinguishing the Flame in Oil and
Spirit Lamps.
I, JOHN RUMBALL, Haughton
Haughton Cottage, Haughton, Bridgnorth Salop
Electrical Engineer, do hereby declare the nature of my said invention to be as
follows:-
My invention relates to apparatus for extinguishing the flame in oil and spirit
lamps (chiefly employed for domestic purposes) when operated by the person
wishing to discontinue the use of the lamp, or when the lamp is upset the said
apparatus acts automatically in extinguishing the same, and explosions and the
consequent danger chiefly arising from the blowing down the chimney or turning
down the wick is prevented.
I will describe my invention to a lamp of the usual construction.
To the wick tube adjacent to the burner and upon each edge 1 arrange a
projection or bracket which carry a plate, which is the same height as the wick
tube, or slightly higher the upper edge of which is turned over this plate has its
two side edges bent outwards and between these edges there is an aperture through
which the wick tube can be seen, the two brackets bave each a small hole, and
each of the side edges of the plate at the bottom also have a small hole,
correspondingly, this admits of a pin being passed through, so that the plate moves
as a joint or hinge, the upper part of the side edges of this plate is provided with a
hole in each, arranged to carry a rod or lever with a thumb plate at its outer end,
which projects out of the burner.
The plate is held in its position by means of a spring of a bowed figure the ends
being secured, and each side coiled upon each end of the pin upon which the plate
works, and bearing against the plate keeps the overturned edge of the plate upon
the wick which is the position when the light is extinguished when the lever is
moved in the opposite direction a projection which is thereon engages with the
wick tube through the aperture and against the resistance of the spring removes
the overturned edge from the wick and it is ready for lighting the pressure of the
lever in this position causing it to remain.
To work the same automatically I arrange a loop upon the projection on the
lever for receiving a short chain having at its other end a metal ball which is
supported upon a projecting piece placed between the burner and the collar, which
is formed at its end as a cup to receive the ball, the ball is of equal weight to
the power given by the hand to release it, so that if by any means the lamp
should pass from its vertical position the ball would fall and the flame would be.
extinguished.

SPECIFICATION.
Improvements in Apparatus for Extinguishing the Flame in Oil and
Spirit Lamps.
JOHN RUMBALL Haughton Cottage, Haughton Bridgnorth, in the County of
Salop, Electrical 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 improvements in apparatus for extinguishing the flame
in oil and spirit lamps.
The improvement, consists in a novel apparatus to be fixed to the wick tube, of
flat burner lamps, for extinguishing the flame by hand, instead of the unsafe
method of blowing out the flame by the mouth, of oil and spirit lamps, also means
of extinguishing the flame automatically, on the lamp being so turned, to the angle
of 45 degrees, or in any unsafe position.
In order that my invention may be more readily understood, I have thereto
appended sheets of drawings, to which I make reference hereinafter.
"Fig. (1)," illustrates the position of the extinguishing apparatus when fixed to
the wick tube of lamp when burning.
"Fig. (2)" illustrates the position of the extinguishing apparatus, on being
turned to the angle of 45 degrees or in a unsafe position.
In these figures A. is the metal support of extinguisher the upper end B. is bent
outwards, and perforated with holes, it has six projections, four bent inwards and
two outwards, the two upper ones are for securing the extinguisher C. the two
middle ones for securing the apparatus to the wick tube, the two at the bottom to
secure the lever bar D, which is used for raising or lowering the extinguisher C.
E shows position of lever, when the lamp is in a safe position, F. shows position of
lever when either turned by hand or by the ball falling off of support as shown in
Fig. 2. G. shows the end of lever bar, used for the handle, for raising or lowering
the extinguisher, and which projects through the mantle of burner, H. shows the
metal support, for holding the metal ball I., when the lamp is in a safe position and
burning, which is secured to the outside of the mantle of burner, the metal ball i,
is secured to the lever by a chain J.
Fig. 1 illustrates the position of metal ball I. when lamp is in a safe position and
burning.
Fig. 2 shows the position of metal ball I. on the lamp being turned to the angle
of 45 degrees, or an unsafe position.
Fig. 1 shows the method of fixing extinguishing apparatus to the wick tube of
lamp.
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) A safety way of extinguishing the flame in oil and spirit lamps without being
blown out by the mouth.
(2) An automatic way of extinguishing the flame in oil and spirit lamps, or
being turned to a unsafe position, or to the angle of 45 degree.
(3) An apparatus to fix to the burner and wick tube of flat burner lamps to
prevent accidents by fire, on being turned over or dropped.
