PROVISIONAL SPECIFICATION.
Improvements in Bicycle Lamps.
I, WILEPAM GEORGE APPLEFORD of Bradford Street, Birmingham in the
County of Warwick Manager do hereby declare the nature of my said invention to
be as follows :—
My invention has for its object: improvements in bicycle lamps,, and has
particular reference to the reflectors to which I obtain a more ready access for the
purpose of cleaning and by which they retain their brilliance considerably longer
than has been the case hitherto while at the same time in many cases the brilliancy
may be increased.
In carrying the first part of my invention into effect I form an aperture in the
back of the lamp sufficiently large to receive the reflector and. in this aperture I fix
a suitable metal rim which is recessed to receive the reflector and projects. into the
interior of the lamp.. This allows the reflector to be readily withdrawn & inserted
from the back of the lamp for cleaning or any other purpose and thereby saves
the difficulty experienced in getting the hand into the front of the lamp when
cleaning the reflector. It also allows of the reflector being so mounted in the recess
as to be adjustable with regard to its distance from the flame of the lamp & also
allows of the reflector being renewed with but little trouble.
The second part of my invention consists of fixing a glass disc or lens in. front of
the reflector so as to prevent any smoke or fumes accumulating on the reflector to
discolour and dull it and the centre of this disc or lens may be of coloured glass so
as to reflect a colour if so desired. This disc or lens may be used in combination
with the removable reflector as above described or it may be applied to an ordinary
reflector.
The third part of my invention consists in forming the reflector itself of a glass
disc or lens of suitable shape the back of which is silvered over preferably with
quick silver to form the reflector; and this reflector I may mount as above described
or fix to the lamp in a similar manner to the present mode.

COMPLETE SPECIFICATION..
Improvements in Bicycle Lamps:
I, WILLIAM GEORGE APPLEFORD, of Bradford Street Birmingham in the
County of Warwick, Manager 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' ir and by the following statement :—
My invention has for its object improvements in bicycle lamps and has particular
reference to the reflectors to which I obtain a more ready access for the purpose of
cleaning and by which they retain their brilliance considerably longer than has
been the case hitherto while at the same time in many cases the brilliancy may
be increased.
In carrying the first part of my invention into effect I form an aperture in the
back of the lamp sufficiently large to receive the reflector, and in this apertnre I fix
a suitable metal rim which is recessed to receive the reflector and projects into the
interior of the lamp. This allows the reflector to be readily withdrawn and inserted
from the back of the lamp for cleaning or any other purpose and thereby, save. the

page_text: difficulty experienced in getting the hand into the front of the lamp for cleaning
the reflector. It also allows of the reflector being so mounted in the recess as to
be adjustable with regard to its distance from the flame of the lamp and also allows
of the reflector being renewed with but little trouble.
The second part of my invention consists of fixing a glass disc or lens in front of
the reflector so as to prevent any smoke or fumes accumulating on the reflector to
discolour and dull it and the centre of this disc or lens may be of coloured glass so
as to reflect a colour if so desired. This disc or lens may be used in combination
with the removable reflector as above described or it may be applied to an ordinary
reflector.
The third part of my invention consists in forming the reflector itself of a glass
disc or lens of suitable shape the back of which is silvered over preferably with
quick silver to form the reflector and this I may mount as above described or fixed
to the lamp in a similar manner to the present mode.
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 shewn my invention applied to the reflector of a bicycle lamp and from
which its application to reflectors of tricycles and other lamps will readily be
understood.
Figure 1 is a view of the back of the outside of an ordinary bicycle lamp shewing
reflector inserted from back.
Figure 2 is a part section through same shewing one mode of inserting the
reflector.
Figure 3 is a similar section but shewing the reflector with the glass disc in
front.
Figure 4 is a similar section shewing a modified mode of inserting the reflector.
Figure 5 is also a similar section shewing a further modification.
Figure 6 is a back view of the mode shewn by Figure 5.
Figure 7 is a front view of Figure 3.
Figure 8 shews a compact reflector with glass disc complete for attachment in
any position.
In carrying my invention into effect I form a suitable aperture in the back D of
the lamp into which I secure the ring d¹ Figure which provided with the
internal screwed thread d into which the cap A¹ is made to screw the reflector
being placed in between the two being thus firmly secured in position & at the
same time capable of being readily removed for cleaning purposes. In this
arrangement the glass B for protecting the reflector may be inserted between the
front of the ring d' and the reflector B & the whole tightened up together and
made dirt proof by the screwing up of the cap or ring A' which is provided with
milled edges to allow of this being easily effected. Many modes may be adopted
for enabling the reflector to be inserted from the back of the lamp such for instance
as shewn in Figure 4 where the casing of the lamp is slightly stamped inwards
at d³ to receive the glass disc B & a metal ring d² is soldered or otherwise fixed
upon the back of the lamp to receive the cap a³ to the inside of which the
reflector A is attached. This cap is made to slide into the ring d³ formed on the.
lamp to receive it & may be retained in position by any suitable catch. In case
where the glass disc B is used for the protection of the reflector A from dirt the
reflector will require to be removed but very seldom and Figure 5 shews a
simple method of securing the reflector and disc into position which is at once
simple & effective.
In this case the lamp back is stamped in round the aperture as before described
& a metal ring of soft or pliable metal d³ is secured on to the back of the lamp
the small teeth d being cut out of the ring and turned down over the back of the
reflector and so retaining it in position.
For removing the reflector for cleaning purposes the teeth would be raised by
the aid of a pen-knife until the reflector was again inserted when they would be
bent over again as before.

page_text: A compact arrangement of reflector and disc is shewn by Figure 8 where the
disc B & reflector are secured together and hermetically sealed by the ring E
which may be spun around the two and this reflector with glass disc complete
may be secured to the lamp in any suitable manner.
may mount the reflector A in such a manner as described without using the
glass B or I may protect reflectors by the glass disc B without mounting them as
herein described or I may use them both in conjunction with each other and the
whole may be permanently fixed in the back of a lamp if so desired.
The reflector instead of being metal may be of silvered glass and the glass disc B
may be coloured while the various details may be modified without departing from
the nature of my said invention.
Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what I
claim is :-
1st. The improvements in lamps by which the reflector is inserted made
removable and secured in position from the outside of the back of the lamp
substantially such as and for the purposes herein described & shewn upon the
accompanying drawing.
2nd. The improvements in lamps consisting of the glass disc B in combination
with the reflector A substantially such as and for the purpose herein described and
shewn upon the accompanying drawings.
3rd. The improvements in bicycle tricycle and other lamps substantially
such as and for the purpose herein set forth & shewn upon the accompanying
drawings.
