PROVISIONAL SPECIFICATION.
Improvements in or connected with Extinguishers for Lamp and Oll
Stove Burners.
We, ELIZA RIPPINGILLE, Lamp and Stove Manufacturer, and WILLIAM
BRANDON, Foreman, both of The Aston Brook Lamp Works, Aston, near
Birmingham, do hereby declare the nature of this invention to be as follows:-
--
The invention has for its object improvements in or connected with that class of
extinguishers for lamp and oil stove burners in which one or more hinged shutters
or flaps is or are employed, and the invention consists of improved and simple
means of mounting and operating such extinguisher shutters or flaps.
For single wick burners we may employ either a single shutter or flap, or two
shutters or flaps closing over the wick; in either case we hinge or pivot the shutter
or shutters to the perforated diaphragm, or to standards carried thereby on one or
both sides of the wick tube or at the ends of the latter, and in such latter case the
hinge or pivot standards may be clear of, or may be attached to, or in contact with.
the wick tube, but we prefer them to be free in order that the shutters or flaps may
have less heat communicated thereto.
In the case of an extinguisher having only a single shutter or flap, we fix the
latter to the hinge or pivot pin, which we prolong and crank at its end to form
an operating lever to the outer end of which we attach a weight, so that for
extinguishing the flame, the weighted lever is raised by hand, thereby closing the
shutter or fap over the wick, whilst the weighted lever will act automatically on
the shutter or flap to uncover the wick.
This arrangement is also applicable to lamps and oil stoves having two or more
burners side by side, in which case one of the crank levers will be weighted, whilst
the other or others will be connected to such weighted lever by suitable link or
links, so that by raising the weighted lever all the shutters or flaps will be caused
simultaneously to extinguish the flames, and the weighted lever will automatically
act upon all the shutters or flaps to cause them simultaneously to uncover all the
wicks.
When employing extinguishers consisting of two shutters or flaps, we also form
their hinge o pivot pins with a cranked lever at one end of each; we fix a weight
to the end of one lever and we connect such weighted lever to the other lever in
such manner that the motion of the weighted lever causes both shutters or flaps to
be simultaneously operated; or we may connect such operating levers by a curved
plate spring which acts automatically to separate the shutters or flaps, but which,
by pressing its ends towards each other, will close the shutters or flaps over the
wick. Or the two hinge or pivot pins may be geared or connected together so as
to simultaneously cause the shutters or flaps to move towards or from each other by
the movement of the weighted lever, or by the rotation of a knob or button on the
end of one of such hinge or pivot pins.
The hinge or pivot pins may pass through separate holes in their carriers, or they
may be slightly cranked and passed through either two holes close together or
through a long shaped hole of suitable length to receive both of the hinge or pivot
pins side by side.

page_text: Improvements in or connected with Extinguishers for Lamp and Oil
Stove Burners.
We, ELIZA RIPPINGILLE, Lamp and Stove Manufacturer, and WILLIAM
BRANDON, Foreman, both of The Aston Brook Lamp Works, Aston, near
Birmingham, 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 invention has for its object improvements in or connected with that class of
extinguishers for lamp and oil stove burners in which one or more hinged shutters
or flaps is or are employed, and the invention consists of improved and simple
means of mounting and operating such extinguisher shutters or flaps so that they
are normally held free of the burners but are readily operated to extinguish the
flame.
The invention is illustrated in the accompanying drawings, in which several
modifications are shown.
Fig. 1 is a plan and Fig. 2 is an end view partly in section of a pair of oil stove
burners each fitted with a single shutter or flap extinguisher and both extinguishers
simultaneously operated.
Fig. 3 is a plan of a single burner showing the cone turned over away from the
wick tube and fitted with a similar extinguisher to that shown at Figs. 1 and 2, and
Figs. 4 and 5 are two cross sections of Fig. 3 with the cone in position and
respectively showing the extinguisher out of action and in action.
Fig. 6 is a plan and Fig. 7 is an end view of a single burner without its cone and
fitted with an extinguisher having two shutters or flaps operated in a similar manner
to those shown in Figs. 1 to 5.
Figs. 8 and 9 are respectively a plan and end view of a burner and extinguisher
similar to those shown at Figs. 6 and 7, but with slight modifications, and Fig. 10
is a plan of a burner and extinguisher without its coue similar to those shown at
Figs. 6 to 9, but showing another modification.
Figs. 11 and 12 are two end views of Fig. 10, respectively showing the
extinguisher out of action and in action.
Fig. 13 is a plan and Fig. 14 is a cross section of parts showing one of the stops at
the ends of the burner to limit the outward motion of the extinguisher flaps or
shutters, and Fig. 15 is a similar cross section to Fig. 14 with the addition of the
extinguisher flaps or shutters resting against the said stop.
In all the figures like parts are indicated by similar letters of reference.
Referring to Figs. 1 and 2, a is the wick tube, the perforated diaphragm, c the
cone and d the wick-raising pinion, which may be of any ordinary character.
The extinguisher for each burner consists of a single flap or shutter e fixed to
pins or axes el mounted in bearings e fixed to the diaphragm at one side of the
wick tube a, but preferably not touching the same so that as little heat as possible
may be communicated to the extinguisher e; the axis el of each extinguisher
cranked at one end and formed with an eye e' by which they are connected
together by a link to cause them to act simultaneously; the crank end e' of one
axis e' has fixed thereto a weight es which acts to keep the extinguishers e normally
in the position shown in Fig. 1 and by the full lines at Fig. 2, but by raising the
weight by hand the extinguishers and the parts connected therewith may be
caused to assume the position shown by the dotted lines in Fig. 2 and the flames
thereby extinguished. A stop 9 acts to limit the backward motion of each
extinguisher e.

page_text: The single burner shown at Figs. 3, 4, 5, has its extinguisher fitted and operated
in a similar manner to that shown at the right hand of Figs. 1 and 2, except that
the eye e and stop gare dispensed with as being unnecessary; in this case the
weight is allowed to fall to the vertical position which will keep the extinguisher e
in a suitable normal position.
It is evident that a light spring might be substituted for the weight e³.
In the example shown at Figs. 6 and 7 the extinguisher consists of a pair of
shutters or flaps e, the axes e' of which are each mounted in bearings fixed to the
diaphragm b, but not touching the wick tube a; one of the axes e is fitted with a
cranked end and weight e, as in the examples shown at Figs. 1 to 5, and the
flaps or shutters e are caused to act simultaneously by means of toothed segments
fixed on the axes e and gearing together. The extinguisher is brought into action
by raising the weight and the latter acts to keep the extinguisher normally clear
of the flame.
In the example shown at Figs. 8 and 9, the extinguisher is constructed and
arranged similarly to that shown at Figs. 6 and 7, except that each axle e¹ has a
cranked end es provided with a weight ³, which weights act to keep the extinguisher
normally free of the flame, and the toothed segments e of Figs. 6 and 7 are
dispensed with and in lieu thereof an arm e' is fixed on one axis e¹ and a cam or
wiper is fixed on the other axis e', which latter parts, on the raising of the larger
weight, cause the shutters or flaps e to act simultaneously and when liberated the
weights e return the parts to their normal position shown in the drawings.
The outward motion of the shutters or flaps e shown at Figs. 6, 7, 8 and 9, is
limited by stops g as in Figs. 1 and 2. It is evident that in lieu of the toothed
segments e, or of the parts e 68, the shutters or flaps may be caused to act together
by levers fixed on the axes e and a link connecting such levers, or a crank pin on
one axis e¹ may work in a slotted arm on the other axis e¹.
of
In the example shown at Figs. 10 to 15, the extinguisher is constructed and
arranged similarly to those shown at Figs. 6, 7, 8 and 9, but in lieu of the weighte
and toothed segments e of Figs. 6 and 7, or of the weights e and parts
Figs. 8 and 9, we connect to the ends of the arms a spring e* which acts to keep
the shutters or flaps e normally resting against the stops g, which in this example
are fixed at the ends but clear of the wick tube a. By pressing together the ends
of the spring ** and consequently the ends of the arms e, the extinguisher shutters
or flaps e are made to act as shown at Fig. 12, and by liberating such parts the
shutters or flaps e are, by the action of the spring, caused to return to the position
shown at Figs. 10, 11, 15.
It is evident that in most of the examples shown the extinguishers may be
caused to extinguish the flame by means of a knob or button fixed on one of the
axes e¹.
The hinge or pivot pins el may pass through separate holes in their carriers as
shown, or they may be slightly cranked and passed through either two holes close
together or through a long shaped hole of suitable length to receive both of the
hinge or pivot pins e' side by side, as will be well understood.
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 :-
1. An extinguisher for lamp and oil stove burners consisting of a shutter or
flap hinged at one side of the wick tube and having a weight or spring acting
upon a cranked arm on the axis of such shutter or flap to keep the same
normally free of the flame, the same being applicable to one or a series of
burners and capable of being operated by hand to extinguish the flame, sub-
stantially as herein shown and described.
2. In a lamp or oil stove having two or more burners side by side, the
combination of hinged extinguisher shutters or flaps, cranked arms upon the
axes of such shutters or flaps, a weight or spring acting upon such cranked

page_text: arms, connections from one to the other of such cranked arms, and a stop for
limiting the action of the parts, substantially as herein shown and described.
3. In extinguishers for lamps and oil stoves, the combination of hinged shutters
or flaps, cranked arms on the axes of such shutters or flaps, means for acting
on such cranked arms to keep the shutters or flaps normally free of the flame,
means for causing such shutters or flaps to act simultaneously, and a stop for
limiting the motion of the same, substantially as herein shown and described.
