PROVISIONAL SPECIFICATION.
Improvements in Lamps for Cycles and the like.
I, GEORGE HARRY WILLIAM DAVIS trading as G. H. W. Davis & Co. of
Edgbaston Works Gough Road, Birmingham, in the County of Warwick, Lamp
Manufacturers, 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 other similar
purposes which are intended to improve the details of the same so that they may
be operated with greater facility and which are as follows:-
To secure the front or dome glass or door in either its opened or closed position
I mount a flat spring in a box behind the door hinge. The spring finishes with a
bow and the end turns inward. A projection is formed on the outer portion of
the door upon which the spring always bears but in such a manner that it is nearly
at rest when the door is quite shut and correspondingly so by means of a hollow in
the spring when the door is open to its full extent. Also in lamps which have
divided bodies with a hinge or joint at the top of one side I fix a pin near the
hinge with a projection tail which bears against the inner portion of the end
when it is shut and being shut and which by the pressure of shutting the lamp is
wound into further tension. Then at the opposite or bottom corner I mount a long
spring with a hooked nose which clips the body of the lamp when closed.
Immediately the hook spring is released the front and one end springs open upon
the top hinge and remains there until again closed. Then in lamps where the body
separates from the bottom I use a spring having a length of coil encased and which
finishes with a turned up nose piece and an acute angled notch which takes hold
and bites a projection on the bottom of the body and so holds it securely. As
these lamps are sometimes required to be secured to the handle or various members
of the machine I fix to the back of the handle or spring carrying portion a circular
jaw with an opposite jaw hinged to the bottom part so as to close upon the bar or
open out, and to a fast projection or bracket I fix a screw for tightening up the
hinged or moving jaw and this screw may be made for the thumb and fingers or
for a key.

Improvements in Lamps for Cycles and the like.
I, GEORGE HARRY WILLIAM DAVIS trading as G. H. W. Davis & Co. of
Edgbaston Works, Gough Road, Birmingham, in the County of Warwick,
Lamp 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 lamps for cycles and other similar

page_text: purposes, which are intended to improve the details of the same so that they may
be operated with greater facility and which are as follows:-
To secure the front or dome glass or door in either its opened or closed position
I mount a flat spring in a box behind the door hinge. The spring finishes with a
bow and the end turns inward. A projection is formed at the outer portion of
the door upon which the spring always bears but in such a manner that it is nearly
at rest when the door is quite shut and correspondingly so by means of a hollow
in the spring when the door is open to its full extent. Also in lamps which have
divided bodies with a hinge or joint at the top of one side I fix a pin near the hinge
with a projection tail which bears against the inner portion of the end when it is
shut & being shut and which by the pressure of shutting the lamp is wound into
furthur tension. Then at the opposite or bottom corner I mount a long spring with
a hooked nose which clips the body of the lamp when closed. Immediately the
hook spring is released the front and one end springs open upon the top hinge &
remains there until again closed. Then in lamps where the body separates from
the bottom, I use a spring having a length of coil encased and which finishes with
a turned up nose piece and an acute angled notch which takes hold and bites a
projection on the bottom of the body and so holds it securely. As these lamps
are sometimes required to be secured to the handle or various members of the
machine I fix to the back of the handle or spring carrying portion a circular jaw
with an opposite jaw hinged at the bottom part so as to close upon the bar or
open out, and to a fast projection or bracket I fit a screw for tightening up the
hinged or moving jaw and this screw may be made for the thumb & fingers or for
a key.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto two sheets of drawings upon
which I have illustrated applications of the same to the several portions which will
enable others to apply the principle as may be required in practice.
Figure 1. is a perspective view of a lamp opened of a such like kind as my
invention may be applied to but it is of course applicable to lamps of other &
various patterns & designs.
Figure 2. is a broken off piece of a lamp in side elevation showing the hood or
dome F with my invention of the spring applied to it.
Figure 3 is a similar side elevation to Figure 2. showing a modification of another
kind of springs applied to it.
Figure 4. is a plan of the spring st as shown at Figure 3 in elevation.
Figure 5 is a side elevation of the back portion of the carrying arrangement
of a lamp showing my invention applied for carrying the lamp on a horizontal tube
or bar of the frame of the machine.
Figure 6 is a similar side elevation to the perevious figure but showing my
device adapted to attach the lamp to a vertical tube or member of the cycle
frame.
Figure 7 is a part sectional elevation shewing my improved method for attaching
the reservoir to the body of the lamp.
It is not always convenient to attach the lamp in the usual manner to the head
of cycles. My invention enables the lamp to be attached to the frame as seen at
Figures 5 and 6. To the back of the carrying portion E of the lamp I attach a clip
consisting of the part A supported or not by the bracket a³ and the upper portion a
hung upon a hinge a³ and operated and fixed upon any arm or member of the cycle
frame R by means of the thumb or other screw a³ tapped into the bracket a¹. In
Figure 5 the device is shown applied to a horizontal member R and in Figure 6 to
a vertical member R.
To maintain the front door F of the hood or cone tightly closed or open I apply
abent plate spring 82² the tail end of which is fastened above the dome & the front
bowed in a similar manner to that shown at Figure 2.
Or the spring may be made of wire as shown at Figure 3. fixed and in plan at
Figure 4 before it is fixed. In this case a piece of wire is bent round at s with

page_text: the coil or coils so that the end s bears upon the top of the front F near its
hinge f¹ which binds it tightly in either its open or closed position. To keep the
body tight when closed down upon the hook snap H I fix a spring S which is coiled
ats and fixed upon the pin s' and which bears against the inner part of the top
of the lamp when closed always exerting a tendency to open it and thus maintaining
it in a tight condition when closed and when the catch spring H is relieved the
body flies open into the position shown by Figure 1.
In lamps where the body separates from the tank I encase a coiled spring wo
and attach it to the reservoir. One end of this spring finishes with a turned up
nose and an acute angled notch which takes into the outwardly turned up
edge won the bottom edge of the side of the body, the edge on the opposite side
being turned up inwardly at 10 and takes under the projection w formed on the
reservoir.
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.
First. The improvements in lamps for cycles and other similar purposes
consisting of the holding device and spring arrangements substantially as herein
described and as shown upon the accompanying drawings.
Second. In cycle and other lamps a such clip as A substantially as herein set
forth and shown by Figures 5 and 6 on the drawings.
Third. The body spring S acting in combination with the spring H substantially
as set forth and shown at Figure 1. of the drawings.
Fourth. The springs 2 and 4, for holding the front F of the hood or cone
substantially as herein set forth and as shown by Figures 2 & 3 on the drawings.
Dated this 3rd day of September 1896.
