Improvements in the Lighting Arrangements of Cycles and other
Road Vehicles.
We, FELIX SINGER, of Halleschestrasse 18, Berlin, S.W., Germany, Engineer,
and PAUL SINGER, of Königgrätzerstrasse 441, Berlin, S.W., aforesaid, Manu-
facturer, 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:
-
According to this invention, road vehicles of all kinds, specially pedal operated
vehicles or cycles, are electrically lighted by utilizing part of the vis viva or
energy of the moving vehicle, taken from one or more of the axles to drive a
suitably constructed dynamo whereby the necessary current is produced for
working the electric lamp or lamps on the vehicle, either direct or through an
electric accumulator.
In the acompanying drawing two arrangements of apparatus are shown for
carrying out the invention but it is to be understood that lighting arrangements
for cycles and other road vehicles according to this invention can be constructed
in other forms and that the invention is not limited to those shown.
Fig. 1 shows the application of the invention to a cycle; and Fig. 2 to an
ordinary road vehicle.
On the driving-shaft w there is a band-pulley d, which by means of a band e,
or other flexible connector, effects the connexion with the driving-shaft f of the
dynamo-machine g.
The dynamo itself is wound to a maximum tension of 30 volts and may advan-
tageously be tightly enclosed by a light steel casing in order to produce as large
a number of lines of force as possible.
The casing with the dynamo (say for 1/25 to 1/32 H.P.) is screwed fast at a
suitable place somewhat according to Fig. 1 under the seat between a, b, and c or
according to Fig. 2 under the driving-seat at h.
From the dynamo machine the conductor of the current is suitably carried to
the lantern i.
The lantern, which consists only of a glow-lamp 7 and a mirror-reflector m,
may have in its internal vacant space k an accumulator which is charged by the
dynamo whilst the lamp itself is not acting, or it may be whilst the lamp is in
action.
The lamp may, of course, be fed altogether from the accumulator-i.e., the
rotational force of the axle of the vehicle may be transferred to the dynamo and
this will then charge the accumulator, which, finally, will provide the lamp with
current.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, we declare that what we
claim is:
1
An electric lighting arrangement for road vehicles of all kinds and especially

page_text: pedal-operated vehicles or cycles, wherein part of the rotative force of the wheel-
axle w due to movement of the vehicle is converted by means of a dynamo-machine
into an electric current for effecting the lighting of the vehicle.
2. An electric lighting arrangement for vehicles according to Claim 1, in
which there are inserted into the circuit between the dynamo g and the lamp
an accumulator which is charged by the said dynamo.
3. The combinations and arrangements of parts constituting the improved
lighting arrangements for cycles and other road vehicles shown in and described
with reference respectively to Fig. 1 and to Fig. 2 of the accompanying drawings.
Dated this 29th day of July 1897.
