Improvements in Attachments for Cycle Lamps.
I, CAMILLUS KOEBEL, of 181 Jackson Boulevard, in the City of Chicago,
County of Cook and State of Illinois, United States of America, Manufacturer,
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 :-
My attachment consists of a rotatable disk adapted to be secured upon a bicycle
lamp in front thereof, and to be rotated by the wind or by pressure against the air
when the bicycle is moving. This disk may have suitable colors, figures or designs
upon its face and has wings upon its periphery for rotating it. When the bicycle
is moved a peculiar and novel effect is produced, showing that the bicycle is moving
and drawing the attention of the public thereto by reason of such peculiarity.
The disks may have designs or colors to correspond with the colors of a club so
that the club members may recognize each other at night. The disk is so arranged as
not to interfere with the light upon the road.
In the drawing Fig. 1 is a side elevation showing the device upon a bicycle lamp ;
Fig. 2, a front view and Fig. 3, a detail view of the clamp.
The disk A is of any desired size and material and has a number of wings B
properly bent to rotate the disk. These wings may be arranged right handed or
left handed as preferred, which will determine the direction of the rotation of
the disk.
Many designs may be used on the disk but I prefer to use the form shown in
Fig. 2. Disk A is a skeleton frame, preferably opaque, and has tongues a running
spirally to the center to form double volutes. Upon the back of the disk and to
close the open spaces in the disk I secure transparent spiral plates C. In the
construction shown in the drawings there are two of these plates, which are preferably
of celluloid like the disk and are preferably of different colors. A single plate,
however, may be used.
The clamp for securing the device to a lamp such as D consists preferably of a
single piece of wire bent to form spring arms E, E¹ having two similar but
oppositely arranged curved arms F, F adapted to fit over the front reflector or
hood D of the lamp. The disk is rotatably mounted upon the clamping device by
a spindle G having bearings, gg, in a piece H secured to the forward part of the
wire. A nut a¹ secures the disk to the spindle. Any other suitable means may be
used for rotatably mounting the disk.
In attaching the device in front of the face or lens the arms F, F¹ are stretched
apart over the front reflector or mouth of the lamp while the extreme ends e fit over
the rim thereof, whereby it becomes securely attached. When the bicycle is moved
the disk rotates, or the force of the wind may rotate it, and the light is affected in a
pleasing manner and attention is also drawn to it.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An attachment for a bicycle lamp as herein shown and described.

lamp in said position.
3. An attachment for a bicycle lamp comprising a rotatable disk provided with
wings upon its periphery and arranged in front of the face of the lamp and a
clamping device securing the disk to the lamp.
4. An attachment for a bicycle lamp comprising a rotatable disk having wings
upon its periphery and arranged in front of the face of the lamp, and a continuous
wire bent to rotatably hold the disk and secure it to the lamp.
5. A bicycle lamp attachment comprising a rotatable skeleton disk arranged in
front of the face of the lamp, transparent material adapted to close the open
spaces of the disk, wings upon the disk and means for securing the attachment to
the lamp.
