An Improvement in Devices for Facilitating the Lighting of Cycle
and other Lamps.
I, WILLIAM HENRY JACKSON, of Melrose, Heaton, Bradford, Yorkshire, Gentle-
man, 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:-
1
My invention relates to an improvement in devices for facilitating the lighting
of cycle and other lamps and refers more particularly to devices of this kind
such as are self contained and designed to be applied to such lamps, the object
of this present invention being to provide simple and efficient means whereby
such devices may be easily and firmly secured in place without the employment
of any skilled labour being required as soldering and other methods of attach-
ment of this kind requiring the employment of skilled labour may be dispensed
with.
In carrying my invention into practical effect, the form of device, to which
this improvement is preferably applied, comprises a hollow cylindrical or conical
body furnished with a fixed collar or shoulder at one end, the other extremity
being cut away in a slanting direction where it is covered with a plate of
flexible springy material roughened or serrated upon its under surface for the
purpose of causing matches to ignite when they are passed through the body
of the said device and beneath the plate.
Now according to this invention, upon the outer periphery of the cylindrical
or conical body of the lighting device, a suitable screw thread is formed, while
I further provide a detachable collar or ring correspondingly screw threaded
upon its inner periphery so that it may be screwed over the body of the said
lighting device for the purpose of securing it in position as hereinafter more
fully described.
In order that my invention may be more fully understood, I will now proceed
to describe same with reference to the accompanying drawings in which Fig. 1
is a side elevation of a lamp lighting device showing my improvement.
Fig. 2 being a longitudinal section, while
Fig. 3 shows the device as inserted through the side of a lamp.
All views are drawn to a considerably enlarged scale and like letters of
reference indicate corresponding parts throughout.
As shown in the accompanying drawings the body a of the lighting device is
screw threaded upon its outer periphery, while at one end it is provided with a
fixed collar or shoulder b, the other extremity being cut away in a slanting
direction as shown, where it is covered by a plate c of flexible springy material
serrated upon its under surface. The moveable collar or ring d is screw threaded
upon its inner periphery and designed to screw over the body a.
In order to insert and secure the device in position, a hole of sufficient size
is bored in the side g of the lamp in such a position as to bring the cut away
extremity of the body a in close proximity to the wick tube, when passed through

page_text: same, and it is firmly secured in place by screwing on the collar or ring d in such
a manner as to tightly grip the side g of the lamp between the fixed collar or
shoulder and the moveable screw threaded collar or ring d.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is-
1/. The combination with a device for facilitating the lighting of cycle and
other lamps; of a removable screw threaded collar or ring d substantially as
herein described and shown with reference to the accompanying drawings and
for the purpose specified.
2. In devices for facilitating the lighting of cycle and other lamps, the com-
bination with an internally screw threaded collar or ring such as d, of an outer
screw threaded body such as a having a fixed collar or shoulder such as b, sub-
stantially as herein described and shown with reference to the accompanying
drawings and for the purposes specified.
