Improvements in or connected with Extinguisher Mechanism for
Lamps.
I HARRY DAIN HINKS, and JAMES HINKS and SON Limited, of Great Hampton
Street, Birmingham, in the county of Warwick, Manufacturers, do hereby declare the
nature of this invention to be as follows:-
This invention consists of the improvements hereinafter described in extinguisher
mechanism for lamps, which said improvements are partly based upon an invention for
"Improvements in or connected with extinguisher mechanism for lamps," for which
letters patents were granted to William Snelgrove, bearing date March 5th 1887.
and numbered 3414; and also upon an invention for "Improvements in or connected
with extinguisher mechanism for lamps," for which letters patents were granted to
Joseph Hinks of the firm of James Hinks and Son Limited, bearing date January
18th 1888, and numbered 808, both of which patents are the property of the said
firm of James Hinks and Son Limited.
The said patented invention No. 3414 of 1887, consists essentially in the employ-
ment of a hanging weight, so arranged with respect to a ring, terminating in a lever,
that on the inclination or tilting of the lamp beyond a certain limit, the weight strikes
against the ring, thereby raising the said lever and disengaging a catch, by which the
extinguishers of the lamp had been held down.
The released extinguishers are raised by a spring, and the lamp extinguished.
Thus on the upsetting of the lighted lamp, the flame is extinguished as soon as the
lamp has acquired an inclination of only a few degrees from the perpendicular, and
the ignition of the contents of the lamp if spilled, is prevented.
The said patented invention No. 808 of 1888, consists essentially in means employed
for the purpose of obviating the use of springs for closing the shutters when raised,
and of the arrangement of levers used therein, and also of modifications of the ring,
hood, or cover embracing or encircling the actuating pendent weight.
In constructing extinguisher mechanism according to this our present invention,
our object is to provide an arrangement of parts, whereby the levers, with their
fulcrum joints, and the interference with the ordinary perforations of the burner body,
are dispensed with.
This improved arrangement admits of some modification, and may be applied in
conjunction with the beforenamed pendent weight, to act automatically, and in such
cases, also that it may be extinguished by hand by means of, or without the said "
weight; also, it may be applied to a nonautomatic extinguishing lamp, where it may
always be extinguished by hand; in which latter case, the manipulative arm, may be
either rigidly attached to the sliding shutter boxes, and capable only of a vertical
motion, that is, parallel to, and with the motion of the said shutter boxes &c.; or, it
may be loosely connected thereto at its inner end, so that to its outer end, a partial
inward and upward sliding motion is imparted, in order to raise the shutter boxes.
We employ in each case, shutters having inclined arms or their equivalents, in
combination with a stop or trip action, so that when the extinguishers are raised a
certain height, such arms &c. come in contact with the said stop or its equivalent, and
the flap is closed over the flame.
As an automatic arrangement, we provide an arm, suitably bent and shaped, the
one end of which, is rigidly attached to the distance or connecting cross bar, between
the two extinguishers, (or in the case of single wick lamps, otherwise rigidly con-
nected to the single extinguisher). This arm is extended through one of the ordinary
perforated (air) slots in the side of the burner body, at that part where bangs the
pendent weight, and terminates in a ring or other suitable form, generally a ring,

page_text: which engages with the said weight as already described in the specifications referred
to. At the outer side of this ring, the metal is shaped further, to provide a lift piece,
so that at will, it may be raised independently of the weight.
Upon the upsetting or tilting of the lanp, the pendent weight by reason of its
upper coned or curved surface, when falling to the one side, moves forward the arm,
and consequently the extinguishers direct, thus obviating the use of levers, and their
fulcrum joints, and also the preparing of bearings for such levers, upon the burner
body, and moreover the friction necessary in the use of such levers is also avoided.
As a nonautomatic arrangement, it may be used as described, with the lift piece at
the end of the ring; or the said arm may terminate with the lift or push piece
without the ring and the weight; or instead of being rigidly attached to the
extinguishers, the inner end of the arm may be loosely connected to the cross bar, or
other suitable part, and bent of a more or less curved form, so that its outer end at
that part where it passes through the perforated slot, rests and rides upon the bottom
of the said slot; its extreme outer end terminating as before, with a push piece or
button.
Thus upon pressing in the push piece or button, the under curved surface of the
arm, rides or slides upon the bottom of the perforation, while its inner end raises the
extinguishers as before described.

COMPLETE SPECIFICATION.
Improvements in or connected with Extinguisher Mechanism for
Lamps.
I, HARRY DAIN HINKS, and JAMES HINKS and Son Limited, of Great Hampton
Street, Birmingham, in the county of Warwick, 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 :-
•
This invention consists of the improvements hereinafter described in extinguisher
mechanism for lamps, which said improvements are partly based upon an invention
for "Improvements in or connected with extinguisher mechanism for lamps," for
which letters patents were granted to William Snelgrove, bearing date March 5th,
1887, and numbered 3414; and also upon an invention for "Improvements in or
connected with extinguisher mechanism for lamps," for which letters patents were
granted to Joseph Hinks of the firm of James Hinks and Son Limited, bearing date
January 18th, 1888, and numbered 808, both of which patents are the property of
the said firm of James Hinks and Son, Limited.
The said patented invention No. 3414, of 1887, consists essentially in the employ-
ment of a hanging weight so arranged with respect to a ring terminating a lever that
on the inclination or tilting of the lamp beyond a certain limit the weight by reason
of its upper inclined surface strikes or presses against the inside of the ring, thereby
raising the said lever, and disengaging a catch by which the extinguishers of the
lamp had been held down.
The released extinguishers are raised by a spring and the lamp extinguished.
Thus on the upsetting of the lighted lamp the flame is extinguished as soon as the
lamp has acquired an inclination of only a few degrees from the perpendicular, and
the ignition of the contents of the lamp if spilled is prevented.
The said patented invention No. 808, of 1888, consists essentially in means
employed for the purpose of obviating the use of springs for closing the shutters
when raised, and of the arrangement of levers used therein, and also of modifica-
tions of the ring, hood, or cover embracing or encircling the actuating pendent
weight.
In constructing extinguisher mechanism according to this our present invention,

page_text: our object is to provide an arrangement of parts, whereby the levers, with their
fulcrum joints, and the interference with the ordinary perforations of the burner body,
are dispensed with.
This improved arangement admits of some modification, and may be applied in
conjunction with the beforenamed pendent weight, to act automatically, and in such
cases, also that it may be extinguished by hand, by means of, or without the said
weight; also, it may be applied to a nonantomatic extinguishing lamp, where it
may always be extinguished by hand; in which latter case, the manipulative arm,
may be either rigidly attached to the sliding shutter boxes, and capable only of a
vertical motion, that is, parallel to, and with the motion of the said shutter boxes &c.;
or, it may be loosely connected thereto at its inner end, so that to its outer end, a
partial inward and upward sliding motion is imparted, in order to raise the
shutter boxes.
We employ in each case, shutters having inclined arms or their equivalents in
combination with a stop or trip action, so that when the extinguishers are raised a
certain height, such arms &c., comes in contact with the said stop or its equivalent,
and the flap is closed over the flame.
We will now proceed to more praticalarly describe how this our invention is to be
performed, with the aid of the accompanying illustrative sheet of drawings, upon
which are figures and letters of reference, similar lotters referring throughout the
several views to the same thing or part, and in which :-
Fig. 1, is a vertical section of the burner; Fig. 2, is a plan of the burner; Fig. 3,
is a vertical section of the burner, as it appears when the lamp is upset; Figs. 4,
and 5, are detailed views of the operating arm; Fig. 6, is a vertical section of the
burner with the pendent weight removed, and the shutters down; Fig. 7, is a vortical
section with the shutters (Fig. 6) raised, and closed over; Fig. 8, is a side part
elevation shewing the tripping action with the shutters down; and Fig. 9, is
a side part elevation, showing the shutters (Fig. 8) raised, and tripped or
closed over.
As an automatic arrangement, we provide an arm a, suitably bent and shaped,
the one end of which is rigidly attached to the distance or connecting cross bar b,
between the two extinguishers c, c, (or in the case of single wick lamps, otherwise
rigidly connected to the single extinguisher. This arm a, is extended through one
of the ordinary perforated (air) slots d, in the side of the burner body, at that part
where hangs the pendent weight e, and terminates in a ring, or other suitable form,
the which engages with the said weight e, as already described in the specifications
referred to.
At the outer side of this ring the metal is shaped further, to provide a
lift piece g, so that at will, it may he raised independently of the weight e.
Upon the upsetting or tilting of the lamp, the pendent weight e, by reason of its
upper coned or curved surface at h, when falling to the one side, moves forward the
arm a,
and consequently the extinguishers c, c, direct, thus obviating the use of levers,
and their fulcrum joints, and also the preparing of bearings for such levers, upon the
burner body, and moreover, the friction necessary in the use of such levers is also
avoided.
As a nonautomatic arrangement it may be used as described, by means of the lift
piece y,
at the end of the ring f; or, the said arm may terminate with the lift or push
piece 9, without the ring f, and the weight e, or instead of being rigidly attached to
the extinguishers, the inner end of the arm a¹, may be loosely connected to the
cross bar b, or other suitable part, and bent of a more or less curved form, so
that its outer end at 1, (see Figs. 6 & 7) where it passes through the perforated
lot d, rests and rides upon the bottom of the said slot; its extreme outer end
terminating as before, with a push or lift piece, or button g¹.
Thus upon pressing in the push piece or button g', the under curved surface of
the arm a¹, rides or slides upon the bottom of the perforation d, while its inner
nd raises the extinguishers c, c, as before described.
The closing of the flaps k, over the tops of the wick tubes 1, to extinguish the
dames is effected as follows:-(as described in the beforementioned specification

page_text: No. 808, of 1888). Each flap is provided with an inclined arm m; n, is a fixed
upright, the top of which is formed with stop pieces o, o.
When the sliding
extinguishers c, c, have been lifted nearly to their full extent, the two inclined
arms m, m, strike against the stop pieces o, o. The continued motion of the sliding
extinguishers causes the said inclined arms to turn upon their pivots p, p, and
thereby to turn the flaps over and cover the wicks and extinguish the flames (see
Fig. 6 & 7).
Upon the arm a', at q, a catch is provided, so that when the arm a', is pressed
inwards (as seen in Fig. 7) the said catch drops behind the bottom of the perforation
through which the arm works, and thus sustains it in that position with the
extinguishers raised, and the flaps k, closed over. When it is desired to lower tho
extinguishers &c., the arm a', is first lifted sufficient to raise the catch q, into the slot,
when it will readily then drop of its own weight.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. In extinguishing mechanism for lamps, the combination of the extended arm a,
with the sliding extinguishers c, c, substantially as described and shown, and for the
purposes specified.
2nd. The combination in mechanism for extinguishing lamps, of the arm a, having
the ring f, and the lift piece g, substantially as described and shown, and for the
purpose specified.
3rd. The combination in mechanism for extinguishing lamps, of the arm a', having
the push piece g', with the sliding extinguishers c, c, substantially as described and
shown, and for the purpose specified.
4th. The combination with the arm a', of the catch y, substantially as set forth, and
for the purpose specified.
5th. The combination of the arm a, having the ring f, and lift piece g, with
the automatic acting hanging weight e, and the sliding extinguishers upon the wick
tubes, all substantially as set forth and shown upon the drawings.
