We, HARRY HINES of the Duplex Lamp Works Birmingham in the County of
Warwick, Gentleman, and JAMES HINKS AND SON, Limited, of the Duplex Lamp
Works, Birmingham aforesaid, Lamp Manufacturers do hereby declare the nature
of this invention to be as follows:-
According to this invention we suspend a pendent frame weighted at its lower end
from some outside part of the burner in such manner that it will swing freely in any
direction. The pendent frame is open ring-shaped or otherwise so formed as to allow
the extinguisher lever to protrude through or pass by it. This lever normally rests
with its lower side or a projection therefrom on a peg or part projecting up from the
lower part of the pendent frame. But when the lamp is tilted and the weighted
pendent frame is thus made to assume an angle with the central and now inclined axis
of the lamp the aforesaid projection from the pendent frame will be withdrawn from
under the extinguisher lever, and a spring acting against the latter will thus be free
to throw its other or inner end up and raise the extingisher or extinguishers. The upper
end of the projection from the pendent frame may be slightly cup shaped so that
the peg on the extinguisher lever rests somewhat firmly therein and will not be removed
therefrom by a slight tilting of the lamp, such as occasioned by carrying the lamp
about.

We HARRY HINKS of the Duplex Lamp Works, Birmingham in the County of
Warwick, Gentleman and JAMES HINKS AND SON Limited, of the Duplex Lamp Works,
Birmingham aforesaid, Lamp Manufacturers 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 :-
According to this invention we suspend a pendent frame, weighted at its lower end,
from some outside part of the burner in such manner that it will swing freely in any
direction. The pendent frame is open, ring-shaped or otherwise so formed as to allow
the extinguisher lever to protrude through or pass by it. This lever normally rests
with its lower side or a projection therefrom on a peg or part projecting up from the
lower part of the pendent frame. But when the lamp is tilted and the weighted
pendent frame is thus made to assume an angle with the central and now inclined axis
of the lamp, the aforesaid projection from the pendent frame will be withdrawn from
under the extinguisher lever, and a spring acting against the latter will thus be free'to
throw its other or inner end up and raise the extinguisher or extinguishers. The upper
end of the projection from the pendent frame may be slightly cup-shaped so that the peg
on the extinguisher lever rests somewhat firmly therein and will not be removed there-
from by a slight tilting of the lamp, such as occasioned by carrying the lamp about.
Referring to the accompanying drawings, in which one mode of carrying this
invention into effect is shown, Figure 1 is a front elevation of the burner with the
pendent weight partly in section and Figure 2 is side elevation with the suspending
eye hook, or bearing a for the pendent weight 6 and the extinguisher lever c partly in
section.
The pendent frame b, weighted at its lower end, is in this case suspended loosely
under the gallery d from the hook a, brazed or otherwise secured onto the outside of
the burner body in such manner that it will swing freely in any direction. The
weighted frame 6 having been suspended the hook a is closed to form an eye and may be
soldered. The pendent frame 6 is as here shown made somewhat ring-shaped, with its
lower part enlarged so as to act as a weight and to allow the extinguisher lever c to
protrude through it. This lever c normally rests with its lower side or a projection c¹
therefrom on a peg 61 projecting up from the lower part of the pendent frame b and
as here shown provided with an enlarged upper part 6. But when the lamp is tilted
and the pendent frame b is thus made to assume an angle with the central and now
inclined axis of the lamp, the aforesaid projection from the pendent frame b will be
withdrawn from under the extinguisher lever C and a
spring e shown in dotted lines,
acting against the latter will thus be free to throw its other or inner end up and raise
the extinguisher or extinguishers. The inner end of the lever c is shown in Figure 1
in dotted lines and acts on the extinguisher in the ordinary way. The upper end
or flat face of the enlargement 62 at the top of the peg 6¹ on the pendant frame b
may under some circumstances be slightly cup shaped so that the peg 6¹ on the

page_text: extinguisher crests somewhat firmly therein and will not be removed therefrom
by a slight tilting of the lamp, such as occasioned by carrying the lamp about. If the
upper face of the part 6 is made flat, as here shown, it should be of such a size (or
about as shown) that a slight tilting will not cause the peg b¹ to be removed therefrom.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
First. In a lamp a weighted frame freely suspended from the outside of the burner
and provided with a projection or part which normally supports the extinguisher lever
and holds the latter in the off position against the action of a spring but is freed there-
from when the lamp is tilted appreciably in any direction whereupon the spring causes
the extinguisher to act substantially as described.
Second. The construction of automatic lamp extinguisher as described with reference
to the drawings.
