PROVISIONAL SPECIFICATION.
Improvements in Lamp-extinguishing Apparatus.
We, JOSEPH MILLER (Machinist) of 62 Barry Street and EDWARD TROY (Foreman)
of 63 Barry Street, Olean, in the County of Cattaraugus and State of New York,
United States of America do hereby declare the nature of this invention to be as
follows:-
Our invention relates to apparatus capable of attachment to any lamp by means
of which should the lamp he overturned or thrown any great distance out of the
perpendicular, the flame will be immediately extinguished.
In one form of the device the lamp body is provided with a vertical tube extending
from the bottom at the centre upward to within a short distance of the burner. The
body is supported preferably upon a tubular pillar having a hollow base which is
supported upon a sub base having a flanged opening in its upper surface. The wick
tube is provided with a vertically-adjustable sleeve, to which at one side the upper
extremity of a rod is attached, said rod passing down through the body a distance
below the same. In the tubular pillar a second rod is pivotally attached to the upper
rod, and the lower extremity of the lower rod is pivotally secured to a dish-shaped
disc which closes the upper opening in the sub-base, the periphery of the disc being
flanged downward to overlap the flange of the sub-base. To the underside of the
disc a pendulum weight is secured by means of a rod. Thus should the lamp by
any possibility be thrown any great distance out of perpendicular, the pendulum
weight will be carried to one side, and the disc will be thrown upward at an angle
to the sub-base whereupon the rods will force the sleeve above the upper end of
the wick tube, and the flame will be instantly extinguished.
By the employment of the pivotally connected rods, a positive operation of the
device is assured, since the greatest throw of the pendulum will not cause the joint
to more than contact with the sides of the tubular pillar.
In another form of the device the tube in the body of the lamp is dispensed
with, and the lamp body may be mounted upon any suitable pedestal. The burner
is, however, provided with a longer body than is usually employed, and the collar of
the burner, adapted to be secured upon the lamp body, is carried inward and flanged
upward. The disc is made to rest upon the inner surface of the said collar, and the
pendulum weight is rigidly secured to the bottom of the said disc in substantially a
similar manner to that before described. Above the pendulum disc a second cup-
shaped disc is placed in the body of the burner, adapted to be normally sustained by
the lower disc, and the upper disc is connected by a rod with the sleeve of the wick
tube. In the operation of this form of device should the lamp be tilted to any great
extent, the pendulum weight will swing to one side, whereupon the lower disc will
be elevated, which will elevate the upper disc and by reason of the rod connection
between the upper disc and the sleeve, the said sleeve will be carried in a perpendicular
line above the upper extremity of the wick tube, and the supply of air being thus
cut off the flame will be at once extinguished.
The light will not be extinguished when the lamp is slightly tipped, as in carrying
it for instance, as the sleeve will not be projected up far enough to affect the flame
until the lamp is carried sufficiently out of the perpendicular to bring the edge of the
disc beyond the centre of the pillar. Thus the weight must be swung far enough to
throw it beyond a perpendicular line extending down from the edge of the disc
when the latter is in its normal position.
In a further modification we employ a casing or jacket adapted to act as a
bracket, having an open lower end and its lower edge carried upward to form an
interior, perpendicular flange, upon which flange the periphery of the disc rests,

page_text: whereby the pendulum weight is adjustably secured upon the pendulum rod, which
rod is, as in the first described construction, secured to the bottom of the disc. To
the central upper portion of the disc is attached a rod which projects upward through
the top of the bracket casing, and to the upper end of this rod, which acts as a lever,
one end of a second lever is attached, adapted to be fulcrumed at or near its centre
to any suitable support, and the opposite end of said lever is attached to the sleeve,
or any suitable device capable of sliding upon the wick tube.
In this construction, which is adapted for cars &c., the bracket carrying the-disc
may be secured at quite a distance from the lamp or lamps, the connection between
the lamps and the lever rods of the device being effected by means of a lever or
levers.

Improvements in Lamp-extinguishing Apparatus.
We, JOSEPH MILLER (Machinist) of 62, Barry Street, and EDWARD TROY
(Foreman) of 63, Barry Street, Olean, in the County of Cattaraugus, and State of
New York, United States of America, 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 :—
Our Invention relates to apparatus capable of attachment to any lamp, by means
of which, should the lamp be overturned or thrown any great distance out of the
perpendicular, the flame will be immediately and automatically extinguished.
Reference is to be had to the accompanying drawings, forming part of this
specification, in which figure 1 is a central vertical section, through a lamp having
our improvement attached; figure 2 is a similar section, through a lamp illustrating
a modified form of the invention; and figure 3 is a central vertical section through
the attachment when constructed for connection with a lamp located at a distance
therefrom. Similar figures of reference indicate corresponding parts in all the
views.
In the form of device illustrated in figure 1, the lamp body 10 is provided with
a vertical tube 11 extending from the bottom at the centre upward within a distance
of the burner. The body 10 of the lamp containing the tube 11 is supported
preferably upon a tubular pillar 12 attached to, or integral with, a hollow base 13.
The said base 13 is in turn supported upon a sub-base 14 having an opening in its
upper surface, the wall of which opening is struck upward to form essentially a
flange 15. The wick tube 16 of the lamp burner 17, which may be made of any
ordinary construction, is provided with a vertically-adjustable sleeve 18 to which
sleeve at one side the upper extremity of a rod 19 is attached. The rod 19 is made
to pass down through the body 10 a distance below the same and in the tubular
pillar 12 a second rod 20 is pivotally attached to the lower extremity of the upper
rod 19, and the lower extremity of the lower rod 20 is pivotally secured to a dish-
shaped disc 21 which disc is adapted to close the upper opening in the sub-base 14,
the periphery of the disc 21 being flanged downward to overlap the flange 15 of the
sub base. To the under side of the disc 21 a pendulum weight 22 is secured by
means of a pendulum rod 23. Thus, should the lamp by any possibility be thrown
any great distance out of the perpendicular, the pendulum weight 22 will be carried
to one side, as illustrated in dotted lines, and the disc 21 will be thrown upward at
an angle to the sub-base, whereupon the rods 20 and 19 will also be carried upward,
which rods will force the sleeve 18 above the upper end of the wick tube and the
flame will be instantly extinguished.
It will be observed that, by reason of employing two rods 19 and 20 and pivotally

page_text: connecting the same, a positive operation of the device is assured; since the
greatest throw of the pendulum 22 will not cause the joint to more than contact
with the sides of the tubular pillar 12.
In figure 2, the tube 11 in the body 10 of the lamp is dispensed with and the
lamp body may be mounted upon any suitable or desired pedestal. The burner 17
is, however, provided with a longer body than is usually employed, and the collar 24
of the burner, adapted to be secured upon the lamp body, is carried inward and
flanged upward, as illustrated at 25. The disc 21 is made to rest upon the inner
surface of the said collar and the pendulum weight 22 is rigidly secured to the
bottom of the said disc in substantially a similar manner to that illustrated in figure 1.
Above the pendulum disc 21, a second essentially cup-shaped disc 26 is placed in
the body of the burner, adapted to be normally sustained by the lower disc and
the upper disc 26 is connected by a rod 27 with the sleeve 18 of the wick tube.
In the operation of this form of device, should the lamp be tilted to any great
extent the pendulum weight will swing to one side, as illustrated in dotted lines,
whereupon the lower disc 21 will be elevated which, in turn, by contact with the
upper disc 26 will elevate the same and, by reason of the rod connection between the
upper disc and the sleeve 18, the said sleeve will be carried in a perpendicular line
above the upper extremity of the wick tube and the supply of air being thus cut off
the flame is at once extinguished. The wick passing from the wick tube 16 may be
carried through the tube discs 21 and 26 to the body of the lamp in any suitable
and approved manner. The light will not be extinguished when the lamp is slightly
tipped, as in carrying it for instance, as the sleeve will not be projected up far enough
to affect the flame until the lamp is carried sufficiently out of the perpendicular to
bring the edge of the disc beyond the centre of the pillar 12. Thus, the weight
must be swung far enough to throw it beyond a perpendicular line extending down
from the edge of the disc when the latter is in its normal position.
In figure 3, we have illustrated a casing or jacket 27ª adapted to act as a bracket,
having an open lower end and its lower edge carried upward to form an interior
perpendicular flange 28. Upon this flange the periphery of the disc 21 is made to
rest whereby it will be observed that this construction closely resembles the con-
struction of the base of the lamp shewn in figure 1. The pendulum weight 22 is
adjustably secured upon the pendulum rod 23 which pendulum rod is as in the
construction shewn in figure 1, secured to the bottom of the disc 21. To the central
upper portion of the disc a rod 29 is attached which rod projects upward through
the top of the bracket casing 27ª and to the upper end of this rod which acts as a
lever, one end of a second lever 30 is attached adapted to be fulcrumed at or near its
centre to any suitable support and the opposite end of said lever 30 is attached in any
approved manner to the sleeve or any suitable device capable of sliding upon the
wick tube. In this construction, the bracket carrying the disc may be secured to
the sides of the car for instance, quite a distance from the lamp or lamps, the con-
nection between the lamps and the lever rods 29 of the device being effected through
a lever or levers 30.
In the operation of this form of device, should a car be overturned to such an
extent as to throw the pendulum to the position shewn in dotted lines the disc will
be tilted as also indicated in dotted lines and the lever rod 29 elevated, whereupon
the said lever rod will act upon the connecting lever or levers 30 and extinguish the
light
We desire it to be understood that, while specific construction has been shewn
and described, equivalent construction may be employed without departing from the
spirit of the invention, the principal feature of the invention consisting of a disc,
a pendulum connected with said disc, and a connection between said disc and a burner.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is ;-
1. In a lamp extinguishing apparatus, the combination, with a loosely mounted

page_text: disc, of a pendulum attached to the said disc and a connection between the said
disc and a burner, substantially as shewn and described.
2. The combination, with a lamp a disc loosely supported within the same and an
adjustable sleeve mounted upon the wick tube of the lamp, of a connection between
the wick tube and the disc and a pendulum capable of manipulating said disc, substantially
as shewn and described.
3. The combination, with a lamp a disc loosely supported within the same and an
adjustable sleeve mounted upon the wick tube of the lamp burner, of a pendulum
weight attached to the said disc and a connection, substantially as shown and
described, between the disc and the wick tube sleeve, as and for the purpose
specified.
4. The combination, with a lamp a disce loosely supported within the same and
a sleeve adjustably held upon the wick tube of the lamp burner, of a pendulum
weight attached to the under side of said disc and a yielding connection between
the disc and the wick tube sleeve all combined for operation substantially as shewn
and described.
5. The combination, with a lamp provided with a vertical tube attached to the
bottom of its body a disc loosely supported in the lamp below the said tube and a
sleeve adjustably held upon the wick tube above the body tube, of a pendulum weight
attached to the under side of the disc and a jointed rod connecting the disc and the
wick tube and passing upward over the body tube of the lamp, all combined for
operation as and for the purpose specified.
