PROVISIONAL SPECIFICATION.
Improvements in Lamps, Specially Applicable to Bicycle Lamps and
the like.
I, ALEXANDER DOUGLAS PRANGLEY, of The Grove, Lower Bebington in the
County of Chester, Clerk, do hereby declare the nature of this invention to be as
follows:-
This invention relates to lamps which have to be lighted out of doors, and in
exposed positions, and the object of the invention is to so construct such lamps
that the wick may be lighted, by means of a match, with certainty, and without
opening the door, when there is a strong wind blowing, and in the case of bicycle
lamps without even having to stop the machine.
I provide, in a convenient position on the outside of the lamp, a roughened
groove along which the head of the match is drawn in the act of igniting by
friction, and at the end of the groove I provide a small hole just opposite the wick;
the hole is just large enough to admit the lighted match, and I usually fit a pivoted
cap which normally covers the hole but which can be moved so as to leave the hole
uncovered.
The roughened groove may be formed in the body of the lamp itself by
stamping, or it may form part of a small fitting adapted to be attached to any
ordinary lamp; in the latter case the fitting includes the groove, the hole and the
cap together with means for securing it to the lamp body.
In lighting the lamp a common wood or splint match is used by preference,
and it is only necessary to press the head of the match against the groove and,
holding it by the end and keeping it square with the groove, to draw it along
towards the hole; the friction of course ignites the match and as soon as the
ignited head comes opposite the hole it slips in and lights the wick, which is just
opposite the hole. It will be seen that it is only necessary to use one hand to do
this so that a rider can easily light his cycle lamp without stopping the machine.

This invention relates to lamps which require to be lighted out of doors and in
exposed positions, and it has for object to so construct such lamps that the
wick can be lighted, by means of.a match, with certainty, and without opening the
door, even when there is a strong wind blowing, and, in the case of bicycle lamps,
without even, having to stop the machine. For this purpose I provide in a
convenient position on the outside of the lamp, a groove having a roughened
surface along which the head of the,match is drawn in the act of igniting it by
friction, and at the end of the groove and about opposite the wick there is provided
a small hole that is just large enough to admit the lighted match. In proximity.
to the hole there may be fitted a pivoted cap, which normally covers the hole but
which can be so moved as to leave the hole uncovered.
The groove with roughened surface may be formed in the body of the lamp
casing by stamping, or it may form. part of a small fitting adapted to be attached
to any ordinary lamp; in the latter case the fitting includes the groove, the
hole, and the cap, together with means for securing it to the lamp body.
Figs. 1, 2, and 3, of the accompanying drawings illustrate a cycle lamp having
my invention applied thereto, Fig. 1 being a side elevation showing the match
opening closed, Fig. 2 a sectional side elevation showing the interior of the lamp
with the match opening uncovered, and Fig. 3 a cross section showing how an
ignited match is caused to project inside the lamp body towards the wick for the
purpose of lighting the latter. Fig. 4 shows a modification of the device for
covering the match hole.
1 is the groove having the roughened surface. It may be stamped in the body
of the lamp casing and be arranged vertically therewith in any convenient
position, such as alongside the ordinary side window 2, when such a window is
employed, and at a point about opposite the wick. The lower end of the groove
terminates in a small hole 3 immediately below which is preferably provided a
slightly projecting lip 3 to prevent the match-head when ignited from passing
accidentally beyond instead of through the hole into the body of the lamp. 4 is a
narrow slot which is arranged below the hole and through which projects a pin
or the bent free end 5 of a plate or cap 6 (Fig. 2), which is pivoted inside the
lamp at 7, and is adapted to slide against the inner surface of the lamp casing;
normally the cap covers the hole 3, but by moving the outwardly projecting pin 5
to one side, the hole 3 can be uncovered so as to admit of the passage of a lighted
match & without admitting gusts of wind as is usually the case when the ordinary
side door of the lamp is opened for this purpose. The lower end of the pivoted
cap 6 may be made sufficiently wide to always cover the slot 4 and prevent air
from entering the lamp therethrough. A spring guide plate 9 adapted to always
bear against the cap may be employed to prevent any possibility of the latter
shaking when the lamp is in use on a.cycle in motion. Instead of being pivotted,
as hereinbefore described, the cover 6, may as indicated in Fig. 4, be arranged to
slide vertically behind the groove.1, its projection 5 for working it then passing
outwards through a vertical slot between the lamp casing and the grooved plate.
In lighting the lamp a common wood or splint match is used in preference.
It is only necessary to hold the match by one end and press the head of the match
against the roughened surface of the groove and then, keeping it square with the
groove, to draw it along towards the hole. The friction of course ignites the
match and as soon as the ignited end thereof comes opposite the hole 3 it slips
through such hole and lights the wick which is about' opposite the hole. It will
be seen that it is only necessary to use one hand to do this, so that a cycle rider
can easily light his lamp without stopping the machine..
My invention can be applied in connection with lamps other than cycle lamps.
of the kind illustrated, as for example' to lamps of a like nature but intended for
the use of policemen, watchmen, and the like.

page_text: Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed I declare that what I
claim is
1. A cycle or other like lamp designed to be used in the open air, provided on
its exterior with a roughened surface and at one end thereof a hole so arranged
that upon drawing the head of a match along the said roughened surface with an
inward pressure it will upon coming opposite the hole pass therethrough and can
be then directly applied to the lamp wick for the purpose of lighting the same,
substantially as herein described.
2. A lamp having a roughened surface and a match hole as referred to in the
preceding claim and provided with a movable cap or cover whereby the said
hole can be kept normally closed substantially as herein described.
6. A lamp provided with the improved means hereinbefore described with
reference to and shown in the drawings annexed for facilitating the lighting
thereof.
