Year: 1896

page_text: Date of Application, 4th May, 1896
Complete Specification Left, 27th Jan., 1897-Accepted, 13th Mar., 1897
I, ROBERT FLUCKE of 22 Kleiner Kirchenweg, Hamburg, Germany, Merchant,
do hereby declare the nature of this invention to be as follows:-
In accordance with the present invention the bicycle is afforded support on
both sides when the rider is mounting, or the bicycle standing still, or moving
slowly, by the lateral auxiliary wheels arranged on the bicycle by which a four
wheeled vehicle, secure against accident, is formed.
On each side of the hind part of the cycle frame, is a stay, capable of turning,
which stay carries a small wheel at its lower end. By means of a spring arranged
on the cycle frame, the stays are pressed backwards, in order to prevent impediment
when riding in the ordinary manner. In the extended position the wheels serve as
lateral supports.
In order to bring the wheels into the extended position, a double armed lever,
operated by hand, is placed at the upper front part of the cycle frame, at the lower
end of which lever a draught chain is secured, which chain runs over rollers and
operates the stays. The extended position of the lever corresponds to the
extended position of the stays. In this position the lever is firmly held by a
spring hook placed on the cycle frame or by other stop contrivance. If the latter
is uncoupled, the auxiliary wheels are raised by the spring. The contrivance can
be employed on any cycle, and may also be transferred to the front wheel fork.

Bicycle with Lateral Auxiliary Wheels.
1, ROBERT FLUCKE of 22, Kleiner Kirchenweg, Hamburg, 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:-
One great inconvenience for the bicyclist has always been the necessity for
dismounting in a crowded thoroughfare, as it is possible only for the most expert
rider to ride slowly and altogether impossible to remain standing still for even the
shortest period. According to the present invention the machine is given support
on both sides by two small auxiliary wheels, arranged on the bicycle.
In the accompanying drawing, Fig. 1 shows an end view and Fig. 2 a side view
of the bicycle provided with the new device.
On either side of the hind wheel a stay b is arranged on the tubing a, which
stays have an up and down movement around k and carry a small wheel c at their
lower ends. By means of a spring d resting against the socket e, the stay b is
generally kept in the position, shown by the dotted lines, so as not to offer any

page_text: impediment in turning sharp curves. In order to bring the stays band with them
the wheels e into operation, the leverf is pushed forward by the rider and is then
secured by the hook i in its position. The chain 9 running over the rollers his
tightened and draws the stays b forward, compressing thereby the spring d. By
unhooking spring d exerts a pressure upon stays b until the latter hold their
original position. The contrivance can also be adapted to the front wheel.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
-claim is:
In a bicycle the combination of lateral auxiliary wheels (c), held in their two
different positions by means of a spring (d), the supports or stays (6) of which
wheels are operated by means of the chain (g) and which chain can be secured in
its tightened state by means of the hook (i), acting on the lever (f), on the lower
-end of which the said chain is fastened, as and for the purpose set forth.
Dated this 15th day of January 1897.
