PROVISIONAL SPECIFICATION.
Improvements in the Method of Lighting Hydrocarbon and
other Lamps.
I RICHARD HENRY COTTER of Ardcanny Glebe Kildimo, County of Limerick,
Ireland, Incumbent of Ardcanny and Chapel Russell do hereby declare the nature
of this invention to be as follows:
This invention consists of a tube of about one and a half inch long, and an
eighth of an inch broad, containing a very small wick-which tube is inserted into
one edge of the burner of the ordinary lamp by removing a similarly-sized portion
of the burner. This tube is jointed, at foot, by a gas-tight joint, to the burner-
from which joint projects a small lever, which lever is acted upon by the ordinary
extinguishing lever of the lamp, in such a manner as that when the ordinary
extinguishing lever is pressed down-the tube, with the small wick lighting, is
moved to one side, beneath a small dome prepared there for it; while at the
same instant the extinguisher extinguishes the main wick-thus a very small
and nearly invisible flame is retained lighting. On raising the ordinary lever,
the small tube, with its lighting wick, returns to its former position alongside the
main wick, and kindles that wick.
Dated this 6th day of November 1894.
RICHARD HENRY COTTER,
Improvements in the Method of Lighting Hydrocarbon and
other Lamps.
I, RICHARD HENRY COTTER, of Ardcanny Glebe, Kildimo, Co. Limerick,
Incumbent of Ardcanny and Chapel Russell, do hereby declare the nature of my
said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention consists in fitting to each wick tube of ordinary hydrocarbon lamps.
a very small tube containing a corresponding lighting wick, a rack being fitted to
one side of the small tube for the purpose of raising and lowering the same by means
of a pinion. Another rack is attached to the lower fork of the forked end of the
handle or lever, which commonly moves the ordinary extinguisher up and down.
These two racks are connected and caused to move simultaneously by pinions placed
transversely at the foot of the main burner, in such a manner as that, when the lever
is pressed down, and the extinguisher rises to extinguish the main wick, the rack
and pinion movement causes the small tube to sink down to the foot of the burner,
conveying with it the lighting wick. When the handle or lever is raised up, with
a slow and steady motion and without jerking, the small tube with its wick burning,
rises to the top and alongside of the main burner, thus conveying its light to and
lighting the main wick. The small wick, before using the apparatus, is carefully set
and wound down by the winder to the lowest possible point consistent with its
keeping alight, and may be made to sink into a cup which hinders any direct light

movement, but the rack and pinion are preferred.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 is a section of an ordinary double flat wick lamp burner, showing the small
tubes c c raised.
Fig. 2 is a similar section showing the small tubes lowered.
Fig. 3 is a perspective view of 5 pinions mounted transversely at the bottom of
the burners.
Fig. 4 represents the ordinary extinguishing lever with the rack d attached
thereto.
Fig. 5 is a view of one of the small lighting tubes c, with the rack attached
thereto.
The tubes cc are preferably curved, as shown, and are made to slide up and down
alongside the burners. The tubes c c are also fitted with winders g g for adjusting
the small wicks. The five pinions e are fitted transversely at the bottom of the
burners and are actuated by the extinguishing lever shown in Fig. 4.
Figs. 6 and 7 show the mechanism in position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in the method of lighting hydrocarbon and other lamps,
substantially as described.
2. The combination with hydrocarbon and other lamps, of small wick tubes
capable of being carried to the main burners and removed therefrom by means of
racks and pinions or links and levers substantially as and for the purposes herein
before described and illustrated by the drawings.
Dated 8th August 1895.
