page_text: Improvements in Cycle Lamps.
I, GEORGE HARRY WILLIAM DAVIS of G. H. W. Davis & Co. of Edgbaston
Works, Gough Road, Birmingham, in the County of Warwick, Manufacturers, 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 has for its object improvements in cycle lamps by which, firstly,
the mounting of such lamps is improved, secondly, the illuminating power is
increased, thirdly, the construction is materially simplified & cheapened, and
fourthly, better and much more simple access is obtained for cleansing the lens
reflector.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a double sized sheet of drawings upon
which I have fully illustrated the nature of my said improvements-and the mode of
carrying the same into effect with several modifications thereto.
Figure 1, is a general side view of one of my lamps.
Figure 2, is an elevation of the top gate looking up.
Figure 3, is a vertical elevation through the two gates showing a modification in
the position of the springs.
Figure 4, is part of a similar side elevation to Figure 1 but showing a
modification in the form of spring.
Figure 5, is a sectional elevation of Figure 4.
Figure 6, is a front elevation of the lens and reflèctor shown in Figure 1.
Figure 7, is a front elevation of the lamp showing a mode of attachment of the
lens reflector.
Figure 8, is a back elevation of the reflector when removed from the lamp shown
in Figure 7.
Figure 9, shows a modification by which the lens and its reflector is made to
slide up with the front of the lamp.
I will first proceed to describe my improvements in and connected with the
mounting of the lamp in connection with which I provide the springs E which are
covered and protected by the top gate B the top ends es being attached to the top
pin or an equivalent part of the top gate while the bottom ends e of the springs
are attached to ears c¹ formed upon the socket C through which the lower pin t
also passes.
The attachment of the end of the spring to the ears is so made that
the lamp is supported by the tension of the springs E. In this arrangement it will
be seen that the springs, gates, and sockets are self contained when removed from
the lamp. In the modification shown by Figure 3 the springs E' are mounted
vertically in a similar manner, only that the bottom of the springs E' are attached
to the bottom pin 6 of the bottom gate while the top of the springs are attached
to ears c formed upon the top gate B, the springs in this case are protected by
flanges which are bent over on each side. In cases where cheapness is of
importance I may use the band spring E' shown by Figures 4 & 5 the one end e*
of which fits in the socket a¹ upon the lamp and the other end e fits in a socket
formed upon the lower gate B. For increasing the illuminating power of my
lamps I form the flutes or convolutions D around the lens reflector which increases
the amount of reflecting light. These flutes may be convex or concave as most
desired and may be ribbed or reeded with the same effect. In the case of the lens
reflector I make this removable from the lamp itself so that it can be readily
cleansed & this I effect by means of the slots d' which are formed in the side of

page_text: the aperture for receiving the lens reflector D' corresponding pins & being formed
on the outside of this reflector which for fixing are inserted in the slots d' the lens
reflector being then given a sharp turn until one of the pins d' meets the stop d'
formed on the inside of the aperture to receive it. The strengthening wire d³ is
put around the aperture and the lens reflector may be made to screw into the
aperture if so desired or the whole front may be made to slide into the lamp as
shown by D' Figure 9.
Having now particularly described and ascertained the nature of my said
improvements and in what manner the same is to be performed I declare that what
I claim is :
1st. The improvements in cycle lamps substantially as and for the purpose
herein set forth and shown upon the accompanying sheet of drawings.
2nd. In cycle lamps the mode of & means for mounting the lamp substantially
as herein set forth and shown by Figures 1, 2, and 3.
3rd. In cycle lamps the band spring E' in combination with the means for
mounting the lamp substantially as and for the purpose herein set forth and shown
by Figures 4 and 5.
4th. In cycle lamps the flutes D substantially as and for the purpose herein set
forth and shown upon the accompanying drawings by Figures 1 and 6.
5th. In cycle lamps the mode of and means for the attachment of the lens
reflector to the lamp substantially as & for the purpose herein set forth & shown
by Figures 7, 8 and 9.
Dated this 9th day of May 1894.
