page_text: I, EDWARD GERARD, 53, Tunstall Street, Edge Hill, Liverpool, Lamp Maker,
do hereby declare the nature of this invention to be as follows:-
Cycle lamps according to this invention are adapted to burn petroleum oil or
volatile liquid. For this purpose the oil container is packed with absorbent
material, which is saturated with the oil or liquid illuminant.
In order to provide sufficient air for the combustion of petroleum or volatile
liquid, 1 form an air chamber above the oil container, through which passes the
wick tube, the sides of the chamber being perforated. Surrounding the wick tube
above the air chamber I provide a casing or direction plate, the top of the air
chamber being perforated between the casing and wick tube so that the casing
serves to direct a current of air into contact with the flame. Said casing is
preferably provided with openings or is cut away so as not to reach to the top of
the air chamber all the way round. The top of the air chamber is also preferably
perforated beyond the casing.
The oil container with its superimposed air chamber is adapted to slide in ledges
provided in the bottom of the lamp case or glazed portion, so as to leave the
container and air casing exposed. There is therefore a free entry for air through
the perforated side of the air chamber, which air enters the lamp in an upward
direction through the perforated top of the chamber, the effect of which is that the
flame is not deflected or blown out.
The casing surrounding the wick tube may be detachable.
As a means of attaching a lamp to a cycle 1 provide the ordinary spring parallel
motion handle with a clip which is adapted to be clamped onto any suitable part
of the cycle frame by a set-screw. Said clip is swivelled in the lamp handle, so`
that it may be turned to suit either vertical or horizontal portions of the cycle
frame.
By the formation of lamp above described I am enabled to burn the vapour of
petroleum, spirit, or volatile liquid, with which the absorbent material before
referred to is saturated, a lighter lamp is provided, and the improved means of
ventilating the lamp obviate the danger of its being blown out.

page_text: Improvements in Cycle Lamps.
I, EDWARD GERARD, formerly of 53, Tunstall Street, Edge Hill, Liverpool,
and at present of 29, Ashfield, Wavertree, Liverpool, Lamp Maker, 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:-
Cycle lamps according to this invention are adapted to burn petroleum oi! or
volatile liquid. For this purpose the oil container is packed with absorbent material,
which is saturated with the oil or liquid illuminant.
In order to provide sufficient air for the combustion of petroleum or volatile
liquid, I form an air chamber above the oil container, through which passes the
wick tube, the sides of the chamber being perforated. Surrounding the wick tube,
above the air chamber, I provide a casing or direction plate, the top of the air
chamber being perforated between the casing and wick tube, so that the casing
serves to direct a current of air, rising through such perforations, into contact with
the flame. Said casing is preferably provided with openings or is cut away so as
not to touch the top of the air chamber all the way round. The top of the air
chamber is also preferably perforated beyond the casing.
In practice I prefer, instead of placing a deflecting plate or casing above the air
chamber, as above described, to cause the top of the air chamber to perform the
function of such plate, as shewn in the accompanying drawing and hereinafter
described.
The oil container, with its superimposed air chamber is adapted to slide in
grooves or ledges provided in the bottom of the lamp case or glazed portion, so as
to leave the container and air chamber exposed when withdrawn from the lamp.
In practice, however, I prefer to dispose said ledges on the back of the lamp, so
that the container is pushed up and down instead of being slid horizontally, as
hereinafter described, and shewn in the annexed drawing.
The deflecting plate or air chamber top may be detachable from the oil container,
so as to provide means of access to the wick tube; but I prefer to make such plate
a permanent part of the lamp case, and the oil container movable independently
thereof.
As a means of attaching a lamp to a cycle I provide the ordinary spring parallel
motion handle with a clip which is adapted to be clamped onto any suitable part
of the cycle frame by a set screw. Said clip is swivelled, in order that it may be
turned to suit vertical or horizontal portions of the cycle frame.
REFERENCE TO THE DRAWING.
Figure 1 is a perspective view of a cycle lamp according to my invention.
Figure 2 is a cross section of the oil container and air chamber.
A is the oil container, which is attached to the body B of the lamp by the
sliding strips a, which slide in the ledges 6 ou the body B, and a suitable hasp or
catch. The container A. has the usual filling aperture, and is packed with absorbent
material. The container is first filled with oil or volatile hydrocarbon liquid, and
that which is not absorbed by the packing is then poured out. The absorbent
material is first soaked in vinegar (or acetic acid) and dried. The wick tube c

page_text: forms an air chamber, air entering through the apertures f in the base of the
hody B and passing up through the aperture e, around the wick tube, to feed the
flame. The air in this air chamber serves as a cooling jacket to the container A.
To the rear spindles of the ordinary spring parallel motion handle I attached a
corrugated metallic spring D, having projections g. The projections g are adapted
to enter slots in a plate i. To the plate i is attached by means of the nut k the
clip 1, which latter can be secured to horizontal or vertical portions of the cycle
frame at will. By compressing the spring D the projections can be withdrawn
from the slots h, and the lamp removed. Figure 3 is a sectional view of the spring D,
projections g, and plate i.
I prefer to form air apertures m around the front of the lamp, and to protect
them from wind by the plate n. In some cases I continue the metallic coned front
to the rear of the lamp, as shewn in Figure 4, to act as a reflector, in which
case apertures p are cut for the wick tube, smoke exit, and illumination of the side
lights.
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. In combination, the oil or volatile hydrocarbon liquid container A, packed
with absorbent material treated as described, the false bottom C in the lamp
body B, forming-in conjunction with the container A-an air chamber, and
which conducts air, entering the apertures f, through the aperture e to the flame
in a vertical direction, and the ledges b and strips a for supporting the container,
substantially as herein described.
2. In combination, the spring D, projections g, plate i and clip 1, as a means of
attaching a cycle lamp to a cycle frame, substantially as herein described.
