PROVISIONAL SPECIFICATION.
Improvements in Cycle and other similar Lamps.
I, HARRY LUCAS, of Tom Bowling Lamp Works, Little King Street, in the
City of Birmingham, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
-;
This invention relates to improvements in cycle and other similar lamps, my
object being to construct a lamp that shall effectively reflect the light from the
interior of the lamp in the required direction, and be so arranged as to permit of
ready access to the burner and to the interior of the lamp for the purposes of
trimming and cleaning.
In carrying my invention into effect I construct a hollow base or reservoir for
containing the oil with the necessary burner and attachments fitted to the same.
At one side or end of the lamp base I fix a spring or other handle or connection
for attachment of the lamp in the required position upon the cycle or other
vehicle. Upon another side or end of the base I form a connection to which is
hinged or pivotted the upper part or body of the lamp.
The body of the lamp is preferably of a circular conical or like configuration,
and having its front or larger face at an angle other than a right angle with the
cone axis, in order that the light may be effectually reflected in an inclined
direction, and thus thrown on the ground in front of the cycle or vehicle. The
lens or glass front is hinged or fitted to the larger end of the lamp body, whilst the
reflector is fitted within the smaller end. The reflector may be rigidly fixed to the
back of the lamp body, but is preferably either hinged or fitted to the body by
any convenient means which will allow of its removal for cleaning or other
purposes. The lamp base is made with inclined or tapered sides to correspond with
the taper of the conical body, and the two parts are securely connected together by
a spring or other catch piece or fastening.
I preferably form the spring clip or catch for fastening the hinged front or
other part to the lamp body by means of a short length of spring wire or strip.
With the front fastening I arrange the wire or like spring metal along the front
edge of the lamp body, and solder or otherwise attach one end of the spring to the
body. The clip or catch is attached to the wire at right angles, or in such a
mauner as to give a slight twist to the wire when the clip is caused to engage with
the lamp front, and the two parts are thus locked or secured together. I some-
times form the chip or catch in one piece with the spring wire or strip which is
attached to the lamp body.
Within the conical body and hinged from the front I place an additional
reflector cone behind the front glass or lens, and this cone I so shape as to make
the bottom part flatter than the upper part, that is the cone is not a true cone,
but is so formed that its apex is lower than the centre of its base or front. By
this device the light rays from the lamp impinge upon the upper part of the
conical reflector, and are sent downwards towards the roadway, while the lower
part of the cone is sufficiently low to allow the flame complete freedom to send
its light through the front glass or lens. I am thus enabled to make a very small
and compact lamp of great illuminating power. The front reflector cone and the
front lens are preferably hinged one over the other, but they may be attached to
the front by other means such as bayonet-joint or pin-catch.
In this lamp I also arrange the base to carry a back having the reflector

page_text: attached to it. The conical lamp body hinges against this reflector and thus closes
in the flame, while leaving the reflector easily accessible for cleaning. This back,
which carries the reflector also carries the hinging arms for connecting to the cycle
or other vehicle.

Improvements in Cycle and other similar Lamps.
I, HARRY LUCAS, of Tom Bowling Lamp Works, Little King Street, in the
City of Birmingham, Manufacturer, 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 :-
This invention relates to improvements in cycle and other similar lamps, my
object being to construct a small and compact lamp of great illuminating power
that shall effectually reflect the light from its interior in the required direction,
and to so arrange the same as to permit of ready access to the burner and to the
interior of the lamp for the purposes of trimming and cleaning.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to :-
Figure 1 is a side elevation of my improved lamp when closed, and Figure 2 a
similar view when the lamp is opened.
Figure 3 is a sectional plan, and Figure 4 a sectional elevation of the lamp.
Figure 5 is a plan of the lamp with its front open.
Figure 6 is a front elevation of the lamp with the body removed.
Figure 7 is a front elevation, and Figure 8 a sectional side or end elevation, of
the reflector.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect I construct a hollow base or reservoir such
as A for containing the oil with the necessary burner and attachments fitted to the
same. At oue side or end of the lamp base I fix a standard or bracket B to which
I attach a handle or connection of any ordinary description for securing the lamp
in the required position upon the cycle or other vehicle.
The body C of the lamp is preferably of a circular, conical or like con-
figuration, with its front or larger face slanted or formed at an angle other
than a right angle with the cone axis, in order that the light may be effectually
reflected in an inclined direction, and thus thrown on the ground in front of the
cycle or vehicle.
The lens or glass front D is mounted in a frame D' which is hinged at the
larger end of the lamp body as hereinafter described. The metal reflector E and
the back lens F, are inserted within the cap E¹ Figure 8, which fits within a
socket or holder F1, Figures 2 and 3, formed upon or attached to the standard or
bracket B, a spring such as F2, Figure 4, being provided to keep the lens and
reflector against the face of the cap.
The lamp body C is mounted upon a saddle or intervening seating such as C,
and is hinged to the side or end of the base A opposite to the standard or
bracket B, being locked or secured in its closed position by means of the spring
catch or fastening piece G. On pressing back or releasing the catch G the entire
lamp body can be turned over on its hinges, thus exposing the burner H as shown
at Figure 2. The lamp base or reservoir A is made with inclined or tapered sides
to correspond with the taper of the conical body C.

page_text: The front or large end of the conical body C is closed by the hinged front glass
frame D. The small end of the lamp body is closed by its abutment against the
standard or bracket B, carrying the back lens and reflector.
The front glass frame D₁ is hinged to a reflector cone J which is itself hinged
to the front end of the lamp body C. I so shape the reflector cone J as to make
the bottom part flatter or of a less inclination than the upper part, as shown in the
sectional elevation at Figure 4. The rays of light from the burner H which
impinge upon the upper part of the cone are thus reflected downward to the road-
way, whilst the bottom part of the cone is low enough to prevent any obstruction
to the passage of the direct rays of light from the burner H and from the back
reflector E. The hinged cone and conical reflector are secured in the closed
position by means of a spring catch piece K.
I attach an ordinary hood such as L to the upper part of the lamp body C and
provide coloured or other side glasses such as M, and other usual fittings and
attachments upon the lamp.
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 :-
1. A lamp having a circular and conical body fitted at its larger end with a
glass front or lens, and a conical reflector, hinged to a base or oil reservoir with
tapered sides and having an attachment standard or bracket carrying a reflector or
lens and reflector, substantially as set forth.
2. In a lamp, the combination of a front glass or lens and a conical reflector,
with a conical or circular body, the front or lens being hinged to the reflector, and
the reflector to the body, substantially as set forth.
3. A conical reflector for the interior of a lamp having the lower part flatter
or of a less inclination than the upper part, substantially as set forth.
4. In a lamp, the combination substantially as set forth of a conical body with a
base or oil reservoir having inclined or tapered sides corresponding with the taper
of the said body.
5. In a lamp the combination of a conical body hinged to an oil vessel, with
a reflector mounted on a standard or bracket fixed to the oil vessel and forming
an abutment for closing the back end of the body, substantially as set forth.
6. In a lamp, the combination of a conical or circular body with a saddle or
intervening seating and a base or oil vessel having a standard or bracket secured
to the same, substantially as set forth.
7. The general construction and arrangement of the improved lamp substantially
as set forth.
