PROVISIONAL SPECIFICATION.
Improvements.in Lamp Extinguishers.
SAMUEL JONES Glenmount House Newtownards Ireland Power Loom Factory
Manager do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in lamp extinguishers that is to say
when the lamp is inadvertently overturned the flame is extinguished.
To carry out this invention, I employ a lever working against the action of a
spiral or other spring pivotted to any suitable part of the lamp burner or support
for globe; one end of this lever is connected to the extinguishing device which
may consist of a loose spring sleeve encircling the wick tube or tubes, and the
other end to a catch piece loosely pivotted to any part of the gallery or support
for globe. This catch piece consists of right angle or two arm piece, one arm
terminating in a catch to hold the outer arm of the aforesaid lever, and the other
arm in a flat or other convenient disc in close and touching proximity with which
is suspended a weight. Any movement of this weight, caused by the tilting of
the lamp will be communicated to the catch holding the lever which releases the
extinguishers and as БСОР as the spring lever is free from said catch the
extinguishers will be brought into operation and the lamp extinguished.
Dated this 15th day of December 1893.

COMPLETE SPECIFICATION.
Improvements in Lamp Extinguishers.
I, SAMUEL JONES of Glenmount House, Newtownards, Ireland, Power Loom
Factory Manager, 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 lamp extinguishers, that is to say, to
devices by means of which, when the lamp is inadvertently overturned, the flame
is immediately extinguished.
In carrying out my invention I employ a lever working against the action of a
spiral or other spring pivotted to any suitable part of the lamp burner or the
gallery or globe support and one end of the lever is connected to the extinguishing
device whilst the other end is connected to a catch piece loosely pivotted to any
part of the gallery or globe support. This piece consists of a right angle or bell
crank lever one arm of which terminates in a catch for retaining the outer end of
the aforesaid spring lever whilst the other arm terminates in a disc or its equivalent
in close and touching proximity with which is suspended a weight. The arrange-
ment is such that any movement of this weight caused by the tilting of the lamp
is communicated to the retaining catch which at once releases the spring-lever
whereupon the extinguishing device is automatically brought into operation and
the lamp extinguished.
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 side view of a duplex lamp burner, with the extinguishing device
attached thereto.

page_text: Fig. 3 is a plan.
Fig. 4 is an end view showing the device as it appears when the lamp is tilted
over.
Fig. 5 is a cross section, on the line - Fig. 3, showing the spring lever in the
extinguishing position.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.
a is the extinguishing lever which is much the same as those in ordinary use, it
is pivotted to the gallery d at a. b.is the spring, which, as will be seen, is, at
one end 6¹, connected to the lever a, and, at the other end 63, to the lamp gallery.
The ordinary snuffers or extinguishers care, as usual, moved up and down the wick
tubes by the lever a. e is a jaw or guide for the lever a. f is the bell crank
lever, which, at one end, has a catch f¹ with a friction roller secured to it, and,
at the other end, has a disc f. This lever is loosely pivotted on a stud g screwed
into a bracket g¹ fitted to the gallery. h is the weight, which, as will be seen, is
provided with an upwardly projecting pin having on it a ball and a disc h³.
The disc h bears against the plate 3 whilst the ball fits in a socket or hole made
in a supporting arm i secured to the gallery.
The lamp extinguishing device is shown in its normal position at Figs. 1 and 2,
that is, with the outer end of lever a resting on or caught by the roller catch, f',
but, when the lamp is inadvertently tilted or knocked over, the weight h, swinging
on its ball and socket support i, h', assumes, on account of its gravity the position
shown at Fig. 4 relative with the tilted lamp. As a consequence the disc f³ is
knocked up by the disc h³ and the bell crank lever f moved sufficiently to free the
lever a and allow the spring b to suddenly pull up its inner end along with the
snuffers c and thereby extinguish the lamp.
The light when burning can be readily put out at any time by merely touching
the ball weight h.
If desired, to insure stability a counter balance weight m or ornament or its
equivalent may be fitted to the opposite side of the gallery from the weight has
indicated in dotted lines at Fig. 3.
The weight or weights may be ornamented.
This automatic extinguishing device may be fitted to other lamps besides the
"duplex."
The device may be modified in the arrangement of its parts and in the details
of construction.
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
consider novel and desire to claim is :
A device for automatically extinguishing lamps when accidentally tilted or
knocked over, constructed substantially as hereinbefore described with reference
to the drawings annexed.
Dated this 14th day of September 1894.
