I, SAMUEL ALBERT JOHNSON Marine Engineer 13 East India Road Limehouse
London E. do hereby declare the nature of this invention to be as follows :-
The process use is by the action of loose Balls, gun metal, steel or otherwise on
certain shutters below the burner.
These Shutters are so arranged and hinged within the burner fittings, that they act
at once when the Lamp is canted or upset.
These small balls are contained in bell-mouthed tubes, which are quite separate
from the Gallery or bottom of the Burner and also from the Wick tube.
These Bell-mouthed tubes are carried sufficiently high, as to allow the loose Balls
within them to act, (when the Lamp is canted or upset) immediately upon the
Shutters, closing them over the flame and thereby extinguishing the light of the
Lamp.
The Hinges of those shutters will be carried by the aforesaid bell-mouthed tubes
quite irrespective of the Wick tube.
The Balls are confined within the Bell-mouthed Tubes & cannot get out of them in
whatever position the Lamp may be.
By this means I attain a perfect automatic self Extinguishing Arrangement for
Lamps of all descriptions either Hydro-Carbon or others.

page_text: I, SAMUEL ALBERT JOHNSON, Marine Engineer, 13 East India Road, Limehouse,
London, E. 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:―
My invention relates to that class of automatic extinguisher which is operated by
the action of loose balls of gun metal, steel, or other metal, on extinguishing shutters
situated below the burner cone.
These shutters are so arranged and hinged within the burner fittings that they act
at once when the lamp is dangerously canted or upset.
The loose balls are contained in bell mouthed or flaring tubes or dishes, preferably
flattened on the side next the wick tube, and which are connected to a plate or fitting,
quite separate from the gallery or bottom of the burner, and also from the wick tube,
but which is so shaped that it can readily be fitted on to the wick tube of an existing
burner, and retain its position thereon with or without soldering.
These bell mouthed or flaring tubes or dishes are carried sufficiently, high to allow
the loose balls within them, to act, when the lamp is dangerously canted or upset,
immediately upon the lower flaps or levers of the extinguishing shutters, and close the
extinguishing jaws or shutters over the flame, and thereby extinguish the light of the
lamp.
The hinges of these extinguishing shutters are carried by the carrier or fitting of
the aforesaid bell mouthed or flaring tubes or dishes, quite independent of the wick
tube.
The balls are confined within the bell mouthed or flaring dishes by the lowor flaps
or levers of the extinguishing shutters, so that they cannot get out of them in what-
ever position the lamp may be.
By these means I obtain a perfect automatic extinguishing apparatus for lamps of
all descriptions, either hydro-carbon or others, which apparatus can be readily applied
to existing lamps
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed, aided by the accompanying drawings, more fully to
describe the same.

DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 are two vertical sections drawn at right angles to each other of a
lamp burner with my improvements applied thereto, and showing the gallery and
cone in section. Figure 3 is a plan or top view of the same.
Figure 4 is a vertical cross section, Figure 5 is a section drawn at right angles to
Figure 4, and Figure 6 is a plan of the bell moutbed or flaring tubes or dishes to hold
the loose balls, and Figure 7 is a cross section. Figure 8 is an elevation and Figure 9
is a plan of one of the extinguishing shutters separately.

page_text: Figure 10 is a sectional elevation representing the burner and extinguishing
apparatus in the position they would assume when the lamp is upset, so as to fall on
its side with the wick tube in a horizontal plane or thereabouts, and Figures 11 and 12
are respectively a side elevation and an end view of the burner and extinguishing
apparatus, in the position they would assume when the lamp is upset, as above
described, but with the wick tube in a vertical plane or thereabouts.
a is the wick tube, b is the cone, and c is the top of the burner collar.
The burner is provided with a wick tube d closed at the lower end by a chamber e
provided with a screw cap e¹ and supplied with oil by the auxiliary or suction wicks f,
as bas before been proposed.
9. g. are a pair of extinguishing jaws or shutters, which are hinged or pivotted
at g', g, to lugs formed on, or carried by, a plate or fitting h, which latter is so
shaped as to fit, and clip firmly, the ends of the wick tube a, and thereby securely
hold it in position on the burner. To the plate or fitting the bell mouthed or flaring
tubes or dishes, to contain the loose bails, are fixed, and the sides of such tubes or
dishes i are so shaped or flared, that, into whatever position the lamp may be upset,
the loose balls shall have a tendency to run up, the inclined sides of the tubes or
dishes i, and thereby act on the lower flaps or levers g³, 92, of the extinguishing
shutters g. g, and thereby extinguish the flame. The side of each of the tubes or
dishes i next the wick tube is flattened to facilitate their application within the cones
of existing burners.
The said lower flaps or levers g³ ³ are also so curved and shaped as to facilitate the
action of the balls thereon, and, at the same time, to prevent the latter escaping
from between such flaps or levers g² y² and the bell mouthed or flaring tubes or
dishes when the lamp is upset.
In order to provide a free passage for the air rising through the burnor, I perforate
the parts g, and i, or form them of perforated metal.
I would here remark that i do not claim broadly the use of loose balls to act upon
extinguishing shutters, as such have before been proposed to be usod, but, in such
case, the balls were mounted on inclined flat, or nearly flat, tables, and their action on
the extinguishing shutters was not so quick or powerful as is desirable.
Having now particularly described and ascertained the nature of my said
invention and. in what manner the same is to be performed 1 declare that what
1 claim is,
1. In automatic extinguishers for lamps, the employment of loose balls, and hinged
or pivotted extinguishing shutters g² 92, in combination with bell mouthed or flaring
tubes or dishes i, substantially as herein shown and described.
2. In automatic extinguishers for lamps, the combination of hinged or pivotted
extinguishing shutters g g², loose balls j, bell mouthed or flaring tubes or dishes i and
plate or fitting carrying lugs ', to which the extinguishing shutters are hinged or
pivotted, the whole being so arranged and fitted as to be capable of ready application
to existing burners, substantially as herein shown and described.
