Improvements in Lamps for Cycles and other Vehicles.
I, JOHN GEORGE AULSEBROOK KITCHEN of 28 Rose Grove, Ardwick in the
County of Lancaster, Mechanician, do hereby declare the nature of this invention
to be as follows:-
This invention relates to lamps for cycles and other vehicles and consists in an
improved construction of lamp, the improvements having for their object the
production of a steadily burning lamp not affected by the wind and throwing a good
light upon the ground in front of the cycle or vehicle, and to render the quantity
of oil contained in the lamp visible.
In carrying out my invention I form the case of the lamp in a hemispherical or
preferably a hemiellipsoidical or similar dished or cupped form with a door con-
taining a glass plate in front of the case. I form an oil reservoir so as to conform
in shape to the lower half of the case. The case may form one side of said
reservoir, the front side being of a similar shape but so that the sides are farthest
apart in the centre of the case and approach each other towards the circumference,
or a separate reservoir of this shape may be placed into the case. At the top the
reservoir is provided with a filling tube protruding from the case and closed by a
cap. At about the middle of the bottom of the cavity formed by the front side
of the reservoir I attach thereto a vertical tube with a slot in front and insert into
the same a glass, closing the top by a cap containing a wick tube with adjusting
pinion, the stem of which passes to the outside of the lamp. Through the glass the
quantity of oil in the reservoir can be seen, and the glass or metal tube may be
Inarked at different levels to indicate the length of time for which the oil supply
suffices.
In front of the reservoir I arrange a metal reflector fitting to the front side of
the reservoir and being of a symmetrical shape in the upper half, so that a hollow
space of similar shape as the reservoir is left between the reflector and the case in
the upper half. The reflector may be made removable to facilitate cleaning, or
be fixed. It contains an opening in the top above the burner; protected by a
shield, for the escape of the smoke, and the case has a number of openings in the
top for the same purpose. Round the edge the reflector has a series of air inlet
holes, and the case is formed with similar holes. Any wind blowing in through the
openings becomes distributed in the space between the reflector and case and cannot
extinguish the lamp.
Side doors for lighting the lamp may be formed at one side or both sides of the
case, closed with glass doors to show side lights, and a small opening formed in the
reflector opposite each door for passing a match through. These side doors however
may be omitted.
The lamp case may be formed with any ordinarily used device for attaching it to
the lamp bracket.

page_text: I, JOHN GEORGE AULSEBROOK KITCHEN of 44, Albert Drive Alexandra
Park, Manchester, late of 28, Rose Grove, Ardwick both in the County of
Lancaster, Mechanician, 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 lamps for cycles and other vehicles and consists in an
improved construction of lamp, the improvements having for their object the
production of a steadily burning lamp not affected by the wind and throwing a good
light upon the ground in front of the cycle or vehicle, and to render the quantity
of oil contained in the lamp visible.
In order that my invention may be more readily understood I have attached
hereunto a sheet of drawings to which I will now refer.
In the said drawings, Figure 1, represents a front elevation of my improved lamp;
Figure 2, a side sectional elevation and Figure 3 a plan in section looking upon
the top of the oil reservoir of the same.
In the several views like parts are indicated by like letters of reference.
I form the case a of the lamp in a hemispherical or preferably a hemiellipsoidical
or similar dished or cupped form with a door b containing a glass plate in front
of the case.
I form an oil reservoir c so as to conform in shape to the lower half
of the case. The case may form one side of said reservoir, the front side c¹ of the
reservoir being of a similar shape but preferably so formed that the sides are
farthest apart in the centre of the case and approach each other towards the
circumference. A separate reservoir of this shape may in some cases be formed to
fit into the case. The drawings illustrate a miniature lamp having a comparatively
large reservoir which is obtained by extending the reservoir o backwards in the
centre part as illustrated by the projection c². At the top the reservoir is provided
with a filling tube c³ protruding froin the case and closed by a cap c. At about
the middle of the bottom of the cavity formed by the front side of the reservoir
1 attach thereto a vertical tube d with a slot d¹ in front and fit tightly into the
same a glass tube d², closing the top by a cap d³ containing a wick tube d* with
adjusting pinion, the stem d' of which passes to the outside of the lamp and
terminates with a milled disc d. Through the glass the quantity of oil in the
reservoir can be seen, and the glass or metal tube is in some cases marked at
different levels to indicate the length of time for which the oil supply suffices, in
the manner shewn by the lines d'.
In front of the reservoir I arrange a metal reflector e, fitting to the front side of
the reservoir and being of a symmetrical shape in the upper half, so that a hollow
space of similar shape as that the reservoir occupies is left between the reflector and
the case in the upper half. The reflector is made removable to facilitate cleaning.
It contains an opening e' in the top above the burner, protected by a shield e², for
the escape of the smoke, and the case may have a number of openings e in the top
for the same purpose. Round the edge the reflector has a series of air inlet holes e,
and the case is formed with similar holes e. Any wind blowing in through the
openings becomes distributed in the space between the reflector and case, and
cannot extinguish the lamp.
Side doors for lighting the lamp may be formed in the well known way at one side
or both sides of the case, closed with glass doors to show side lights, and openings
formed in the reflector opposite each door for passing a match through. These
side doors, however, may be omitted.

lamp bracket.
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 improved construction of lamp substantially as hereinbefore described
and illustrated in the drawings attached hereunto and for the purposes set forth.
Second. In a lamp in which the wick or burner is carried by a tubular pedestal
in communication with the lower part of the reservoir, the arrangement and use of
a clear glass level indicator in said pedestal substantially as described hereinbefore
and illustrated in the drawings attached.
Third. The improved construction of vehicle lamp in which the reservoir forms
part of the lamp case and a loose reflector is arranged so as to leave space
between the case and reflector through which space the air is let into the lamp and
the products of combustion are carried out of the same.
