I, FRANCIS ROBERT BAKER of Arcade Chambers, Snow Hill Birmingham in the
County of Warwick, Engineer, do hereby declare the nature of this invention to be
as follows:-
The object of my present invention, is to provide lamps with self acting or automatic
extinguisher appliances or means, whereby a lamp is automatically extinguished, by
the act of lowering the wick within its wick tube or box, by the wick winder, and on
the other hand, the raising of the wick for lighting, pushes aside or moves out of the
way, the extinguisher appliance or means.
I will describe my invention in connection with an ordinary single wick hydro-
carbon lamp, although the same may be used with lamps having two or more wicks;
and my said invention consists in arranging the extinguisher within the inside of the
wick tube, in such a manner, that no part of the extinguisher is exposed to view.
;
I take an ordinary wick tube, and upon one side, and near the top thereof,
I provide an inside sunken part, or an extinguisher recess, wherein the said
extinguisher lies, when the wick is in position for lighting and which said ex-
tinguisher consists of a length of thin strip or sheet metal, secured at its lower part
to the inside of the wick tube, or at the bottom of the recess in the wick tube, while
its other end is free, and springs over the top end of the wick, on the said wick being
lowered within its tube or case; that is, the extinguisher part consists of a tongue
like strip of thin sheet metal, of the full inside breadth of the wick tube, and with its
upper free end inclined to an obtuse angle with respect to the other part, and when
extinguishing, the side and top thereof, entirely cover or enclose up the upper
portions of the wick, but when the lamp is lighted, the extinguisher lies within a like
shaped recess or sunken cavity, which is raised or sunken outwardly, from the inside
of the wick tube.

page_text: The action of extinguishing and lighting is as follows
:-
The lowering of the wick within its wick tube, brings its upper or lighting end
below the inclined inside top of the extinguisher appliance, and thus allows the
said extinguisher to automatically spring forward or come out of its recess so as to
bring the front boundary edges of the inclined top part, in juxta position to the
opposite inside of the wick tube, so as thereby to entirely enclose the top portions of
the said wick, and extinguish it.
The raising of the wick for lighting, presses back the extinguisher into its recess,
by the top part of the wick impinging against its inside upper part.
In applying my invention to benzoline lamps, I make the extinguisher in two parts
or halves, with independent stems which when extinguishing, the top parts come in
intimate contact with each other, so as to enclose the wick thereunder, while the said
top parts or upper ends, carry half round, or other shaped extinguisher tops, which
cover over, or cover up, the top open end of the wick tube, and which said wick tube
has upon its two opposite inside parts, recesses, wherein the extinguisher stenis lie,
when the wick is lighted.

page_text: I, FRANCIS ROBERT BAKER of Arcade Chambers Snow Hill Birmingham in the
County of Warwick, Engineer, 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:-
The object of my present invention is to provide lamps with self acting or automatic
extinguisher appliances or means, whereby a lamp is automatically extinguished by
the act of lowering the wick within its wick tube or box, by the wick winder, and on
the other hand, the raising of the wick for lighting, pushes aside or moves out of the
the extinguisher appliance or means.
way,
I will describe my invention in connection with an ordinary single wick hydro-
carbon lamp, although the same may be used with lamps having two or more wicks ;
and my said invention consists in arranging the extinguisher within the inside of the
wick tube, in such a manner, that no part of the extinguisher is exposed to view.
I take an ordinary wick tube, and upon one side, and near the top thereof,
1 provide an inside sunken part, or an extinguisher recess, wherein the said
extinguisher lies, when the wick is in position for lighting; and which said ex-
tinguisher consists of a length of thin strip or sheet metal, secured at its lower part
to the inside of the wick tube, or at the bottom of the recess in the wick tube, while
its other end is free, and springs over the top end of the wick, on the said wick being
lowered within its tube or case; that is, the extinguisher part consists of a tongue
liko strip of thin sheet metal, of the full inside breadth of the wick tube, and with its
upper free end inclined to an obtuse angle with respect to the other part, and when
extinguishing, the side and top thereof, entirely cover or enclose up the upper portions
of the wick, but when the lamp is lighted, the extinguisher lies within a like shaped
recess or sunken cavity, which is raised or sunken outwardly, from the inside of the
wick tube.
The action of extinguishing and lighting is as follows-
The lowering of the wick within its wick tube, brings its upper or lighting end
below the inclined inside top of the extinguisher appliance, and thus allows the said
extinguisher to automatically spring forward, or come out of its recess, so as to bring
the front boundary edges of the inclined top part, in juxta position to the opposite
inside of the wick tube, so as thereby to entirely enclose the top portions of the said
wick, and extinguish it.

page_text: The raising of the wick for lighting, presses back the extinguisher into its recess,
by the top part of the wick impinging against its inside upper part.
In applying my invention to benzoline lamps, I make the extinguisher in two parts
or halves, with independent stems, which when extinguishing, the top parts come in
intimate contact with each other, so as to enclose the wick thereunder, while the said
top parts or upper ends carry half round or other shaped extinguisher tops, which
cover over, or cover up, the top open end of the wick tube, and which said wick tube
has upon its two opposite inside parts, recesses, wherein the extinguisher stems lie,
when the wick is lighted.
Or the extinguisher or shutter part may be jointed and made to fall by its own
weight, on the lowering of a wick below the top of a wick case or tube.
I will now proceed to describe with reference to the accompanying drawings, the
manner in which the same is to be performed.
Figure 1 is a vertical section of a lamp burner, provided with an extinguisher
device, made according to my invention; and which said figure 1 represents the
wick lowered within the wick tube or wick case, and the position which the wick
shutter assumes for extinguishing. Figure 2 represents a like section, but with the
wick raised, and the spring extinguisher shutter pushed aside. Figure 3 is a side
elevation of figuro 2.
The same letters of reference indicate corresponding parts in figures 1, 2 and 3.
a is a volatile hydro-carbon lamp burner, and is a wick tube, having a shutter or
extinguisher recess 2, (near its upper part) wherein the extinguisher or shutter c lies,
when the wick is in a position for lighting, or is lighted; and which said extinguisher
or shutter, consists of a length of thin strip spring metal of the inside breadth of the
wick tube, and with an angular top c², for the enclosing in, of the upper part of the
wick the stem of which said extinguisher is secured at its lower end or bottom part,
to the wick tube, by soldering, riveting or by other means-d is a winder of the
ordinary kind, passing through piercings in the side of the wick tube, and d² is the
winder axis, which on being rotated, raises or lowers the wick e.
Figure 4 represents in vertical section, and figure 5 in plan, a burner provided with
an outside extinguisher, which encloses in at its upper part, the wick, and the top of
the wick tube, Figure 6 is an elevation of the wick tube and extinguisher separately.
a is the burner, the wick tube, and c, c is an extinguisher in two parts, which on
the inclined upper parts c², c², coming together as represented, enclose or cover up the
upper part of the wick tube, on the wick e being lowered by the winder d within its
case, for extinguishing.
Figures 7 and 8 represent my invention applied to a benzoline lamp, which is
exactly the same in construction, as in figure 1, other than that the extinguisher
shutter is made in two parts, which enclose over and upon the top of the wick, on the
wick being lowered within its wick case or tube as in figure 8, and pressed aside
and out of position by the yielding of the metal, on the wick being raised as in
figure 7.
;
Figure 9 represents another form of my invention, in which the extinguisher
shutter, is made to fall into its extinguishing position, by gravity, or by its own
weight and which said figure 9, which is a vertical section, shows the shutter pushed
aside, and the wick in its normal condition, ready for lighting. Figure 10 is a front
elevation of the said figure 9, and figure 11 is the same, with the extinguisher in
action, or with the open top of the wick tube enclosed or covered up, by a hinged
flap or shutter, weighted or counterpoised; so that on the retiring of the wick within
its tube, operated by the winder, the extinguisher shutter or flap falls by its own
weight, and so extinguishes or puts out the flame. Figure 12 is a plan of figure 11,
and figure 13 is an enlarged view of the upper part of wick tube and extinguisher,
while figure 14 shows a modification, in which the extinguisher shutter or flap, when
extinguishing, lies horizontally.
The same letters of reference indicate corresponding parts in figures 9 to 14 both
inclusive.

page_text: a is the burner part of the lamp, is a wick tube, e is an extinguishing shutter or
flap, hinged or jointed at c, e, by trunnion or pivot ends working within holes made
at opposite points in side ears, carried by the wick tube; and in order to prevent the
shutter from opening too far, it is provided with a heel e³, at its back end. d is the
winder, the winder axis, and e the wick.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is,
First An automatic extinguisher, consisting of an extinguisher, or an extinguisher
shutter, (or shutters) disposed and working within and below the top of a wick tube
of a lamp, and which said tube has a recess, (or recesses) wherein the inclined top of
the shutter, (made from a strip of spring inetal) lies, when the wick is in a raised
or in a position for lighting, substantially as described and set forth in figures 1, 2, 3,
7 and 8.
Secondly Making extinguishers, or extinguisher shutters in two parts, which are
placed and work on the two opposite outsides of a wick tube, and with their inclined
tops enclosing the top of the wick and wick tube, substantially as described and set
forth in figures 4, 5 and 6.
Thirdly Making the tops of automatic extinguisher shutters inclined, for the
purpose substantially as described and set forth.
FourthlyAn extinguisher, or an extinguisher shutter; consisting of a hinged
and weighted flap, tongue or strip of metal, working above the top open end of the
wick tube or tubes of a lamp; and which said flap, tongue or cover, falls into its
extinguishing position, by gravity, or its own weight, substantially as described and
illustrated in figures 9, 10, 11, 12, 13 and 14 of the accompanying Drawings.
Dated this Seventh day of April 1887.
