Improvements in Portable Oil Lamps, particularly applicable to
Cycles and the like.
We, PERCY ARCHIBALD NIX, and DANIEL HENRY ROGERS, both of
59 Bishopsgate Street, London, Gentlemen, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in portable oil lamps particularly
applicable to cycles and the like and has for its object to provide a lamp which
will be light, compact, and cheap, and not having a movable reservoir to slide in
and out, but a self-contained reservoir holding a much greater quantity of oil than
most lamps in general use.
In carrying our invention into practice we provide a vessel of tin plate or other
suitable metal (for preference cylindrical in shape) the ends of which form the
back and front of the lamp respectively.
The lamp is divided into two compartments, namely an upper and a lower com-
partment, the latter is covered over with tin plate or other metal, thus forming the
reservoir for the oil, said reservoir having a semi-circular depression or channel'
running from back to front, in the centre of which an ordinary burner or wick
conductor is inserted furnished with a pinion connected by a wire with a button at
its outer extremity for the purpose of raising or lowering the wick. The upper
compartment or portion forms the lid and is hinged at one side for convenience in
filling, and lighting the lamp also for renewing the wick and cleaning purposes, and
is further provided with a clip or fastening at the side opposite the hinge. This lid
may be slotted so as to take the aforesaid pinion wire.
The back of the lamp is divided horizontally in the middle, the lower half or
portion forming the back of the oil-reservoir the upper half is attached to the
portion of the side which opens, forming the back of the lid, and is furnished with
a reflector exactly behind the flame. The lid has an opening at the top, for
ventilation, which is covered over at a sufficient distance to allow smoke and hot
air to escape, while it prevents rain from entering. The front of the lamp is not
divided as the back is, but has a circular opening in the upper part for the insertion
of glass or talc or a bulls eye lens, opposite the reflector, in front of which a hood
may be provided, with a reflecting inner surface, to confine the rays of light and
direct them on to the road. The upper part of the front is provided with a flange
turning inwards, which is overlapped by the lid when closed, whereby rain is
excluded. The lamp is provided with the ordinary means for attaching to the
velocipede.
By a modification of our invention we may make an arrangement for refilling the
lamp without the necessity of opening it, by means of a tube on the outside com-
municating with the reservoir, and covered with a screw cap, which arrangement
would be found useful when necessary to refill the lamp in windy weather.
We do not restrict ourselves to materials, dimensions, or to the precise form or
placement of the several parts of this, our invention.

Improvements in Portable Oil Lamps, particularly applicable to
Cycles and the like.
We, PERCY ARCHIBALD NIX and DANIEL HENRY ROGERS, hoth of
59 Bishopsgate Street, London, Gentlemen, 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 :-
Our invention relates to improvements in portable oil lamps particularly
applicable to cycles and the like, and has for its object to provide a lamp which will
be light, compact and cheap, and not having a movable reservoir to slide in and
out, but a self-contained reservoir holding a much greater quantity of oil than most
lamps in general use.
In carrying our invention into practice, we provide a vessel of tin plate or other
suitable material (for preference cylindrical in shape) the ends of which form the
back and front of the lamp respectively, and the lamp is provided with a lid
capable of fitting closely over the circular back and front. The lamp is divided
into two compartments, namely an upper and a lower compartment, the latter is
covered over with tin plate or other material, thus forming the reservoir for the
oil, said covering plate having a semi-circular depression or channel running from
back to front, in the centre of which an ordinary burner or wick holder is inserted
and furnished with a pinion connected by a wire with a button at its outer extremity
for the purpose of raising or lowering the wick. The upper compartment or
portion forms the lid and is hinged at one side for convenience in filling and lighting
the lamp also for renewing the wick and for cleaning purposes, and is further
provided with a clip or fastening at the side opposite the hinge.
The back of the lamp may be divided horizontally in the middle, the lower half
or portion forming the back of the oil reservoir, the upper half in this case is
attached to the portion of the side which opens forming the back of the lid, and is
furnished with a reflector exactly behind the flame. The hid has an opening at the
top for ventilation which is covered over at a sufficient distance to allow smoke
and hot air to escape, while it prevents rain from entering. The front of the lamp
is not divided as the back, but has a circular opening in the upper part for the
insertion of glass, or talc, or a bulls eye lens, opposite the reflector, in front of
which a hood may be provided, with a reflecting inner surface, to confine the rays
of light and direct them on to the road. The lamp is provided with the ordinary
means for attaching to the velocipede.
We may provide an arrangement for refilling the lamp without the necessity of
opening it by means of a tube on the outside communicating with the reservoir, and
covered with a screw cap, which arrangement would be found useful when necessary
to fill the lamp in windy weather.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which
Fig. 1 is a front elevation of my improved lamp showing the general form and
construction,
Fig. 2, is a plan of same with the lid open,
Fig. 3 is a side elevation with lid open and
Fig. 4 is a front elevation of lamp showing part of back carried by lid.
My improved lamp consists, as shown in Fig. 1 of a cylindrical shaped vessel
made of tin plate or other suitable material, provided with circular discs f & b
(Figs. 2 & 3) which form the back and front of the lamp respectively, a curved
lid is provided to fit closely over the top of the front and back f, b, the edges of
which are bent over or flanged to form a good bearing surface and also to keep out
wind and rain. The lower part of the lamp is covered with a sheet of thin metal
or other suitable material and forms the compartment used as the oil reservoir,

page_text: this metal plate is centrally provided with a circular depression or channel c
extending from front to back within which is placed a wick holder h, the wick
being raised by means of a pinion carried by the rod x and turned by the button d.
A small thumb screw or clamp n is provided for the purpose of holding the wick
holder tightly in position and to prevent rattling. A tube t is carried from the
reservoir to the outside of the lamp and provided at its outer extremity with a
screw cap m to enable the lamp to be conveniently filled with oil without opening
the lid. The lid may be simply a curved flap hinged at one side bearing on the
flanged parts of the back and front fb (Figs. 1, 2 and 3,) or the back b may be
divided into two parts at the upper part being carried by the lid 7 (Fig. 4) in
which case the anti-vibrating attachment, which is of usual construction would' (in
the case of a cycle lamp) have to be secured to the lower half only of the back b.
The lamp is provided with a reflector placed directly behind the wick holder,
while the front of the lamp is furnished with a shade the front of which can be
opened and which is normally held in position by the catch 9. Holes vv and ware
provided in the body of the lamp for the purpose of supplying the flame with a
sufficient quantity of air, while the lid is provided centrally with an opening O
covered by the hood y to allow the hot air to escape.
"
As the channel c is not absolutely necessary for the proper working of this lamp
it may obviously be dispensed with when required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A new or improved lamp more especially applicable for cycling purposes in
which the reservoir or oil container is formed integrally with the lower part of the
lamp, substantially as herein described and shown with reference to the accompanying
drawings.
2. The new or improved lamp substantially as herein described and shown in the
accompanying drawings.
