Improved Lamp for Cycles and similar Vehicles.
I JOHN GEORGE AULSÉBROOK 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 similar vehicles and consists
in an improved construction of the lamp and parts thereof, the object of the
improvements being to produce a lamp throwing a good light upon the road and
easily cleaned.
The improved lamp consists of a front and back part connected together by a hinge
at the bottom and a spring catch near to the top. The front part is formed in the
shape of an annular tube of an approximately elliptical section so disposed that the
longer axes of the section form a frustrated cone having the larger diameter at
the front. At the bottom of the tube there is a backward extension which together
with the lower portion of the tube forms the oil reservoir and has the wick tube fixed
on its top. The glass or lens of the lamp is fixed in the annular tube near to the
back thereof, and the tube is preferably flattened at the back for the second or
back part to fit against it. At the top of the annular tube is a filling hole that
can be closed airtight by a cap or button, and an internal pipe descends from this
hole to the level of the oil in the reservoir below the wick, so that the air is
enclosed in the upper part of the tube and prevents the lamp being filled with oil
in excess.
The back part of the lamp consists of a dished reflector with a cylindrical rim
which is cut out at the bottom to fit over the extension of the reservoir and preferably
formed with a lug on each side for a pivot screwed into the reservoir so as to
form a hinge.
The bottom of the rim is perforated with small holes for the admission of air
and the top formed with a shielded opening for the escape of smoke. The back
of the reflector has any ordinary suitable device attached to it for fixing the lamp to
the lamp, bracket. The rim may be formed with side openings closed by glass for
side lights.
By unlatching the spring catch, the whole front part with the wick tube can be
turned down for lighting the lamp and cleaning the reflector and glass.
In a modification of the lamp 1 may divide the annular tube by a plate or plates at
the level of the oil so as to cut off the reservoir from the upper part of the tube and
form openings for letting out the smoke in the upper part of the annular tube.

Improved Lamp for Cycles and similar Vehicles.
I, JOHN GEORGE AULSEBROOK KITCHEN of Albert Road, Alexandra Park,
formerly of 28 Rose Grove, Ardwick, Manchester 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 similar vehicles and consists in
an improved construction of the lamp and parts thereof, the object of the improvements
being to produce a lamp capable of containing a large supply of oil, throwing a good
light upon the road and easily cleaned.
On the drawing appended hereunto,
Figure 1 shows a vertical section,
Fig. 2 a side view and
Fig. 3 a horizontal section of one form of the improved lamp.
The improved lamp consists of a front part and a back part connected together by
a hinge at one side and a catch at the opposite side. The front part is formed in the
shape of an annular tube or chamber a the inner side a¹ of which forms a frustrated
cone while the outer side a² may be cylindrical or of any other suitable shape. In
some cases I may make the annular tube of an approximately elliptical section so
placed that the diameter of the tube is larger at the front than at the back. At the
bottom of the annular tube there preferably is a backward extension or chamber b
which together with the tube a forms the oil reservoir and carries a wick tube c
provided with the usual adjusting pinion c¹ and spindle c² for raising or lowering the
wick. The back chamber b may communicate with the annular tube a through.an
opening in the wall of the latter, in which case the chamber 6 and lower part of
the annular tube a form the oil reservoir; which arrangement is more particularly
applicable where the annular tube is of comparatively large diameter. Oil is filled
in through the opening d at the top closed by a screwed cap d' and a pipe may
be connected to this opening descending to the bottom of the annular. tube, so that
air is enclosed in the upper part thereof and the overfilling of the oil reservoir
prevented. Instead of the annular tube a and back chamber being in open
communication, they may be kept separate and connected by a small pipe e with
a cock e as shewn on the drawing, in. which case the annular tube a can be filled
with oil to any height, and the back chamber filled from time to time from
it through the pipe e. The glass lens p is fixed in or attached to the annular
· front part.
The back part of the lamp consists of a dished reflector f with circular rim f¹ which
is cut out at the bottom to fit round the back extension b of the reservoir. The front
and back parts are connected by a hinge g and a catch g' or equivalent sliding bolt,
which may be at the sides as shown on the drawing. Or the back part may be
formed with a lug on each side at the bottom end as indicated by dotted lines on
Figure 2, through which a pivot fixed to the reservoir passes and forms a hinge,
while a catch is arranged at the top, by which arrangement the front part can
be turned down and the oil run out of the back chamber b into the annular tube a.
The bottom of the rim is perforated with small holes covered on the inside with
baffle shields . Other holes i may be arranged in the part m fixed to the reflector
for attaching the usual spring carrier n thereto, and a hole i¹ covered by a shield
made in the back of the reflector J. Through these holes air is admitted into the
lamp to the burner. The top is formed with a shielded hood o of any suitable form
for the escape of smoke. The rim may be formed with side openings closed by glass
for side lights.

page_text: In a modification of the lamp I may divide the annular tube a by plates at the level
of the oil so as to cut off the reservoir from the upper part of the tube and form
openings for letting out the smoke in the upper part of the annular tube. In that
case the annular tube a may be made broad and the wick tube c attached to the inner
side of it.
с
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. The improved construction of lamp substantially as herein before described.
2. In a lamp for cycles and similar vehicles the arrangement of an annular tube or
chamber (a) with or without a backward extension (b) forming the oil reservoir
substantially as herein before described and illustrated by the drawings.
