PROVISIONAL SPECIFICATION.
Improvements in Lamps for Cycles and in the Manufacture of
the same.
I, FREDERICK JOHN SMITH, of 62 Sidbury Worcester in the County of
Worcester Cycle Maker, do hereby declare the nature of my said invention to be
as follows:-.
My invention has for its object Improvements in Lamps for Cycles and in the
Manufacture of the same, by which I produce a lamp which, while considerably
cheapened in production, is not liable to be effected by the heat while at the same
time it is more easy of access and is mounted upon a special form of spring which
considerably lessens the vibration and is much more simple cheap and effective,
than those which have hitherto been in use.

In carrying my invention into effect I form the top and two sides of the body of
the lamp of one piece of metal, a hole being provided in the top for the emission of
the heat fumes. Over this hole or aperture I form a bent shield which is attached
to each side of the top by means of tongues which are passed through holes and so
bent over in the form of clips by which it is secured without the use of solder.
then place a square wind guard or shield outside the previous one which is secured
by means of turning over the edges of the back and front of the top of the lamp
as to form two grooves into which the two edges of the outer windguard slide.
The ends of the two sides of the body of the lamp are kept in position by two
bands of metal, one back and one front and in the square formed by the sides and
these bands I fit the vessel of the lamp which is so arranged as to form its bottom
being secured in position at the back by a projection which clips the rear band and
by a spring clip which correspondingly clips the front band, thus forming a very
easy and effective fastening for the reservoir part of the lamp. Doors are hinged
both at the back and front of the lamp so as to give easy access in both directions
the lens being fixed in the front door and the supporting spring to the rear door.
This spring which I find to be specially suitable for the support of these lamps, is
formed by a length of wire, each end of which is bent over into two coils before
being bent down and attached to the socket which fits upon the projecting arm
formed upon the machine to receive the lamp.

COMPLETE SPECIFICATION.
Improvements in Lamps for Cycles and in the Manufacture of
the same.
I, FREDERICK JOHN SMITH, of 62 Sidbury Worcester, in the County of
Worcester, Cycle Maker 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:-
0 My invention has for its object. Improvements in Lamps for Cycles and in the
Manufacture of the same by which I produce a lamp which, while considerably
cheapened in production, is not liable to be effected by the heat while at the same

page_text: time it is more easy of access and is mounted upon a special form of spring which
considerably lessens the vibration and is much more simple cheap and effective
than those which have hitherto been in use.
In carrying my invention into effect I form the top and two sides of the body of
the lamp of one piece of metal, a hole being provided in the top for the emission
of the heat fumes. Over this hole or aperture I form a bent shield which is
attached to each side of the top by means of tongues which are passed through
holes and so bent over in the form of clips by which it is secured by means of
turning over the edges of the back and front of the top of the lamp so as to form
two grooves into which the two edges of the outer windguard slide. The ends of
the two sides of the body of the lamp are kept in position by two bands of metal,
one back and one front and in the square formed by the sides and these bands I
fit the vessel of the lamp which is so arranged.as to form its bottom being secured
in position at the back by a projection which clips the rear band and by a spring
clip which correspondingly clips the front band, thus forming a very easy and
effective fastening for the reservoir part of the lamp. Doors are hinged both at the
back and front of the lamp so as to give easy access in both directions the lens being
fixed in the front door and the supporting spring to the rear door. This spring
which I find to be specially suitable for the support of these lamps, is formed by.a
Jength of wire, each end of which is bent over into two coils before being bent
down and attached to the socket which fits upon the projecting arm formed upon
the machine to receive the lamp.
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.
Figure 1., is a general view of a lamp with both doors open and reservoir
removed which is shown underneath.
Figure 2., is a cross section through same but with reservoir attached.
Figure 3., is a front elevation of the lamp.
Figure 4., is a sectional plan.
・
Figure 5., is a view of the spring attachment showing a modification.
In carrying my invention into effect, I form the top and two sides A of the body
of the lamp, of one piece of metal the hole a' being provided in the top for the
emission of the heat fumes. This hole is covered by the bent shield B which is
attached to the top A by means of tongues & which are pressed through holes and
so bent over as to form clips by which it is secured without solder. The wind-
guard or shield D is then formed outside the previous one B and is secured by
turning over the back and front edges a² of the top of the lamp thus forming
two grooves into which the two edges of the windguard D slide. The two sides of
the body A are kept in position by the two bands of metal or square frame E into
which the top of the reservoir or vessel F fits being secured thereto so as to form
the bottom of the lamp by means of the projection f which clips or rests upon
one of the bars or part of the frame E while the spring clip is provided to clip
the other part of the frame or any suitable catch made to receive it. The door H
containing the lens is hinged to the body A at while the door J upon which the
supporting spring K is mounted, is hinged to the body A at j' thus enabling easy
access to be made to the whole of the interior of the lamp. The edges a of the
sides A are turned over to obtain strength and also on two sides form a suitable
socket for receiving the hinge pin of the doors. The spring K upon which my
lamp is mounted is formed as shown in Figure 1 the wire K being bent over into
one or two more coils in the manner shown one end being attached to the lamp,
the other bearing any suitable socket L for attachment to the cycle and the further
prevention of vibration or shock to the lammp may be prevented by the coiled
springs shown in Figure 5 the main spring K in this case being mounted to
slide in the sockets the travel of the spring K being controlled by the expanding
coiled springs. The casing of the back of the lamp or door may be made to
cover these coiled springs from view.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. Improvements in lamps for cycles and in the manufacture of the same
substantially as and for the purpose herein set forth and shown upon the
accompanying drawing.
2nd. In lamps for cycles the spring K with or without the coiled springs
substantially as and for the purpose herein set forth and shown upon the
accompanying drawings.
