PROVISIONAL SPECIFICATION.
Improvements in Cycle Lamps.
JOSEPH LUCAS and HARRY LUCAS trading as Joseph Lucas & Son of The
Tom Bowling Lamp Works, Little King Street Birmingham, Lamp Manufacturers
do hereby declare the nature of this invention to be as follows:-
Our improvements relates to cycle lamps and are as follows-
Firstly. We combine the reflector of the lamp with the bridge form of top as
commonly used on cycle lamps, so that the top and reflector can be removed
together for cleaning.
Secondly. We find the wind guard or basher now commonly placed on the inside
of the ventilation holes of the lamp to prevent the wind blowing direct to the flame
is insufficient for its purpose and we remedy this defect by providing an additional
basher or wind guard to cover the holes on the outside also.
Thirdly. We make the socket of the lamp to lock on to the bracket iron as
follows We have commonly used an adjustable socket for fixing the lamp on the
bracket iron, the adjustment being obtained by a push-up plate which reduces the
thickness of the socket, and a pinching screw, and we now make this adjusting
socket into a locking one also by using a pinching screw with removable winged
piece or head and making a peg on the inner end of the screw to project inside the
push-up plate when tightened on the bracket iron and the said peg to go into the
elot or hole now commonly made in bracket irons and so prevent the lamp being
pulled off until the screw and peg are screwed outward.
Fourthly. Instead of making a separate slide holder for the sliding side glass of
the lamp we make the grooves or slide holder out of the metal forming the body of
the lamp by turning or folding the edges of the metal or the sides of the opening
to form grooves for the glass slide to run in.

Improvements in Cycle Lamps.
We, JOSEPH Lucas and Harry Lucas, trading as Joseph Lucas & Son, of The
Tom Bowling Lamp Works, Little King Street, Birmingham, 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:
Our improvements relate to cycle lamps and consists:-First, in combining the
reflector of the lamp with the detachable bridge form of top. Secondly, in fitting
an additional basher or wind-guard to cover the ventilation holes in the body of
the lamp on the outside thereof in addition to the usual basher or wind-guard
placed on the inside of the body of the lamp. Thirdly, in making the pinching
screw used for contracting the size of the adjustable socket of the lamp with a peg
D

page_text: adapted to engage with the slot in the lamp bracket, and in making the head of the
said screw detachable so as to act also as a locking screw, and fourthly, in making
the grooves or slide holder for the frame carrying the side glasses of the lamp out
of the metal forming the body of the lamp, by turning over or folding the edges of
the said metal on the sides of the opening, the objects being;-First, to enable the
top of the lamp and the reflector to be removed together for cleaning. Secondly,
to more effectually prevent the wind blowing on to the frame of the lamp through
the ventilation holes. Thirdly, to securely lock the lamp to the bracket adapted
to carry it at the same time that it is fixed thereto, and lastly, to generally
facilitate and improve the manufacture of cycle lamps.
We attain these ends in the manner illustrated by the accompanying drawing,
in which :-
Figure 1 is a view in side elevation-partly in section-of a lamp embodying our
improvements, and Figure 2 is a view-partly in section-in front elevation
thereof.
Figure 3 is a view in side elevation showing the method of attaching the reflector
to the detachable top of the lamp.
Figure 4 is a view in front elevation showing the head of the locking screw, and
Figure 5 is a view of the removable head of the said screw, and
Figure 6 is a view in section on an enlarged scale showing the construction of
the grooves or slide holder for the sliding side glasses.
Throughout the views similar parts are marked with like letters of reference.
Dealing with the first part of our improvements. The reflector A is attached to
the detachable top B of the lamp-which is made of rectangular form to fit in the
top of the body X of the lamp and is held engaged therewith by a catch such
as b-by means of a small bracket piece a or by any other suitable and convenient
means so that it forms one piece with the said detachable top and can therefore be
removed from the lamp with the said top.
Dealing with the second part of our improvements. A second basher or wind-
guard C is placed outside the ventilation holes x, x, in the sides of the body X of
the lamp in addition to the usual basher or wind-guard D placed on the inside of
the body X of the lamp.
Dealing with the third part of our improvements. The contracting plate E
of the socket F of the lamp is pressed forward by a screw G threaded into a
socket F¹ on the back of the socket F. The inner end of the screw G is reduced
to form a pegg which projects through the plate E and engages with the usual
slot y in the lamp bracket Y and thus prevents the lamp from being removed from
the bracket surreptitiously or until the screw G is screwed backwards or
outwards. The outer end of the screw G has two or more slots g', g', cut in it
to receive the fans h, h, of the detachable head or key H for operating the said
screw, the slots g', g, in the end of the screw G being tapered away as they
approach the centre of the screw so that the said screw cannot be operated by an
ordinary screw driver or its equivalent. We do not however limit ourselves to
this particular device as the outer end of the screw and the detachable head or
key may be made of any other suitable specific shape to engage with each other,
so long as the shape imparted to the outer end of the screw is such that it cannot
readily be operated by any of the ordinary articles used for such purposes.
Dealing with the fourth part of our improvements. The grooves j, j, for the
sliding frame K carrying the side glasses k are formed by bending back and turning
over the edges of the metal of the body X of the lamp at the sides of the openings
therein as shown by Figure 6.
The other parts of the lamp to which no reference has been made present no
movel features and may be of the ordinary construction.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction herein before described and illustrated by the accom-
panying drawing, but that we hold ourselves at liberty to make such changes and
alterations as fairly fall within the spirit and scope of our invention.
