PROVISIONAL SPECIFICATION.
Improvements in Lamps suitable for Cycles and other Vehicles.
We OSCAR SCHWARZ and JUSTUS WALDTHAUSEN, both of Wittelsbacher-
strasse 4, Munich, in the Empire of Germany, Merchants, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a lamp for cycles, or vehicles having an elegant form
and light weight, and capable of being dismounted so that it can be easily cleaned.
The lamp consists of a parabolic reflector in the focal point of which is the flame.
The other parts of the lantern are arranged directly on the paraboloid and the
reflector is not as usually enclosed in a larger or smaller casing. The window of
the lantern is formed in the known manner by a lens. For fastening on the cycle,
the well known spring operated parallelogram is used. The oil receiver is connected
detachably with the lantern and can be detached from the lantern, either alone or
with the burner. The same is fixed by a spring into which reaches a pin on the
receiver. In the paraboloid is a flat socket, into which is put the burner, kept
there by friction. On this burner is detachably fixed the socket of the oil receiver,
for instance by a closure so that after having released the pin either the oil receiver
with the socket or the latter with the burner may be removed.
The admission of the air to the flame is effected by a series of air-holes in the
parabolic reflector and protected against the influence of the wind by protecting.
plates provided on the front and on the sides.
The chimney is closed by a detachable cap with air holes and can therefore be
cleaned from dirt and soot.
By this arrangement of the parts the lamp receives a pleasing exterior and the
weight is diminished as much as possible. Also it is very easily operated and
cleaned. By the arrangement, that the burner of the lamp and not only the wick
is guided directly in the socket, the transpiration of oil does not enter the interior
of the lamp where it would dim the reflector, but it is again conducted out between
the socket and the burner. Finally it may be mentioned that in consequence of the
peculiar connection of the combustible-receiver, warming and evaporisation of the
combustible is excluded.

COMPLETE SPECIFICATION.
Improvements in Lamps suitable for Cycles and other Vehicles.
I, OSCAR SCHWARZ and JUSTUS WALDTHAUSEN, Merchants, both of
Wittelsbacherstrasse 4, Munich, in the Empire of Germany, 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 a lamp for cycles or vehicles having an elegant form
and light weight and capable of being dismounted, so that it can be easily cleaned.

page_text: In the annexed drawing Fig. 1 is a longitudinal section of this lamp, whilst Fig. 2
shows a plan view and Fig. 3 a front elevation thereof.
The lamp consists of a parabolic reflector a in the focal point of which is the
flame b. The other parts of the lamp are arranged directly on the paraboloid and
the reflector is not as usually enclosed in a larger or smaller casing. The window
of the lamp is formed in the known manner by a lens. For fastening on the cycle,
the well known spring operated parallelogram d may be used.
The oil-receiver e is connected detachably with the lamp and can be detached
from the lamp either alone or with the burner. The same is fixed by a spring f
into which reaches a pin g on the receiver. In the paraboloid is a flat socket
into which is put the burner i kept there by friction. To this burner is detachably
fixed the socket k of the oil-receiver, for instance by a bayonet-joint /, so that after
having released the pin g either the oil-receiver e with the socket & only or with
the latter and the burner may be removed.
The admission of the air to the flame is effected by a series of air-holes m in the
parabolic reflector and protected against the influence of the wind by protecting
plates provided on the front and on the sides.
The chimney is closed by a detachable cap o with air-holes and can therefore be
cleaned from dirt and soot.
By this arrangement of the parts the lamp receives a pleasing exterior and the
weight is diminished as much as possible. Also it is very easily operated and
cleaned. By the arrangement that the burner of the lamp and not only the wick
is guided directly in the socket /, the transpiration of oil does not enter the interior
of the lamp where it would dim the reflector, but it is again conducted out between
the socket and the burner. Finally it may be mentioned that in consequence of
the peculiar connection of the oil-receiver, warming and evaporisation of the
combustible therein is excluded.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is ;-
1. A lamp having an uncovered parabolic reflector a arranged to have the flame 6
of the burner in the focal point and on which reflector the oil-receiver e with the
burner i is arranged to be easily detachable (for instance by a spring f with pin g)
in such a manner that either only the oil-receiver or the latter with the barner can
be detached, said lamp being suitable for attachment to cycles or other vehicles.
2. In the lamp as in Claim 1 the arrangement of the oil-receiver in such a manner
that it is completely free from the paraboloid and guided only through a small
socket in the latter, whilst it is kept in this position by means of an appropriate and
easily detachable connection.
3. A lamp having an uncovered paraboloid reflector forming a casing with a
transparent front and an oil-receiver attached thereto, substantially as described,
and a socket-piece for a removable chimney cap o substantially as set forth.
