Improvements relating to Bells for Velocipedes.
I, FRANZ DICK, Manufacturer, of Telleringstrasse, Benrath, near Düsseldorf,
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 that class of bells or alarm devices, which are
caused to ring, when a friction wheel is brought into contact with the tyre. In
the following description reference will be made to the accompanying drawing
which represents a cycle bell and accessories embodying my invention. Fig. 1
being a side view of the mechanism; Fig. 2 a plan of the same and Fig. 3 a
side view in a different position of the mechanism.
The friction wheel may be situated behind the bell or in front of the same,
and the bell is preferably arranged in duplicate, as usual, two bells g being
connected with each other, and the strikers being arranged on both sides of
the friction wheel, in such a manner, that the striker s situated on one side acts
on one bell, while the striker s situated on the other side acts on the other bell.
The strikers are adapted not only to turn on their respective pivots p, p²,
but also to slide on the same. Consequently, they will turn outward, when
caused to revolve, but will recede easily after the impact.
In the example shewn in the drawing, the bell g is not lowered for setting it
in action, but remains stationary, and the friction wheel f only descends. The
bell is attached by means of an arm A to the cycle fork or to any convenient part
of the cycle frame, and the arm A supports also the fulcrum h¹ for the lever h
carrying the friction wheel.
A spring acting on the said lever h tends to lift the wheel of off the tyre t
and to press it against the bell. Consequently the friction wheel f serves also as
a damper which prevents the bells from sounding accidentally during the motion
of the cycle. For setting the friction wheel in motion, the extremity of the
lever his lifted by means of a cord or rod c, and thereby the mechanism placed in
the position represented by Fig. 3.
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 alarm apparatus for velocipedes having a pair of bells, a friction wheel
situated behind or in front of the same, and a pair of pivoted and sliding strikers
arranged on both sides, so that each is adapted to strike from outside against one
of the bells, substantially as described.
2. In an alarm apparatus of the type described, a friction wheel mounted on a
ever adapted to turn toward the tyre, and to press the friction wheel against

page_text: the bell, when the apparatus is out of action, but to withdraw the wheel from the
bell, when the apparatus is set in action, substantially as described.
3. A cycle alarm apparatus constructed and adapted to operate as described and
shown by the drawings.
