COMPLETE SPECIFICATION.
An Improvement in Cycle Lamps.
We, FRANK POWELL and FRANK HANMER, trading together as Powell and
Hanmer, of 232 Aston Road, Birmingham, Warwickshire, Lamp Manufacturers,
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 :—
This invention has reference to oil lamps for bicycles tricycles and other
velocipedes and consists of the hereindescribed improved method of securing the
reflector to the oil fount which we do by means of the spring which is usually fixed
on the back of the oil fount to bear against the inside of the back of the lamp
body and prevents the oil fount from rattling and also when the lamp is opened to
propel the oil fount forward for convenience of removing the fount.
We thus
arrange for the said spring to serve two purposes and we cause the reflector to be
perfectly firm and secure when the reflector and oil fount are in position in the
lamp body and the latter is closed but the reflector is quite free to be removed
from or replaced on the oil fount for cleaning when the latter is removed from the
lamp body.
We will describe our invention by referring to the accompanying drawing
on which Fig. 1 is a front view of an ordinary oil fount for a cycle lamp with the
reflector and spring arranged according to this invention; Fig. 2 shews the same
parts as viewed from the back; Fig. 3 shews the said oil fount and Fig. 4 shews
the reflector with spring separately as viewed from the back; Fig. 5 is a front
view of the reflector and spring and Fig. 6 is a sectional plan of the stem of the
reflector and the spring on line X X of Fig. 4.
The same letters of reference indicate the same parts in all the figures of the
drawing.
A is the oil fount and B is the reflector which we prefer to make of circular
form as shewn concave in the front and convex at the back. This reflector is fixed
to a stem C which projects downwardly and takes into a socket E which is fixed
to the back of the oil fouut A. At a short distance above the bottom end c¹ of
the stem C we fix by the rivet for by other means the bow shaped spring F
which is usually fixed to the back of the fount A. The stem C is by preference
made with a central outwardly projecting rib c³ which strengthens the stem and
as shewn in Fig. 6 forms a space at each side of the rivet f between the spring F
and the stem C for the back e¹ of the socket E to fit in this portion e¹ of the socket
being by preference slotted downwardly at e as shewn in Fig. 3 to clear the
rivet f.
When the oil fount A with the reflector B attached thereto as shewn in Figs. 1
and 2 is placed in the cycle lamp and pushed home the outer ends of the spring F
come into contact as usual with the inside of the back of the lamp and the
spring F presses the stem C of the reflector B against the oil fount A and thus in
combination with the socket E effectually secures the reflector B in position and
at the same time has the usual effect of preventing the oil fount A from rattling
and of propelling the oil fount A forward when the lamp is opened. When the
oil fount A with its reflector B attached as in Figs. 1 and 2 are removed from the
cycle lamp the reflector B can readily be removed from the oil fount A for
cleaning or other purposes by merely lifting the reflector out of the socket E.
Although we prefer to make the reflector B of circular form as shewn still our
invention is not limited to this particular shape as it will be evident that the shape
of the reflector B may be varied without departing from the nature of our
invention as it may for instance be of square oblong or polygonal form.

page_text: 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. In a cycle lamp and in combination with the oil fount thereof, a reflector
provided with a stem adapted to fit in a socket on the back of the oil fount and
having fixed to the 'stem a spring adapted to act against the back of the lamp
and press the reflector stem against the oil fount, substantially as and for the
purposes described.
2. In combination with the oil fount of a cycle lamp the reflector made with the
stem C adapted to fit in the socket. E on the oil fount and having fixed to the stem
the spring F, substantially as described.
3. The combination with a cycle lamp body of an oil fount provided with the
reflector B made with the stem C adapted to fit in the socket E on the oil fount
and having fixed to the stem the spring F for the purposes and substantially as
described.
