Improvements in Cycle-roundabouts.
I, CARL HERMANN JOKISCH, 21, Aeussere Plaumschestrasse, Zwickau, Saxony, in the
Empire of Germany, Mechanician, 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 an improved cycle-roundabout intended to serve as a
means for teaching cycling and likewise as a device for purposes of amusement and
enjoyment.
The invention
shown in the accompanying drawing, in which
Figure 1 represents the roundabout in elevation ;
Figure 2 is a horizontal section on the line xx, of Figure 1.
Figure 3 an adjustable guide-arm in side elevation partly in section and
Figure 4 a plan of the same also partly in section.
This improved cycle-roundabout substantially consists of a stationary supporting
column a, which is su tably fixed to the ground and the upper part of which is
provided with an umbrella-shaped roof or awning b for protecting persons and
objects, underneath, from the effects of the weather.
ball-bearing c, is caused to turn around the column a; this rotary disc being provided
A rotary disc d'arranged in a
with a number of arms or rods e which serve to receive the adjustable guide arins h.
These guide aris (see Figures 3 and 4) are capable of sliding in a socket or cylinder g
formed in the arms or rods e, for the purpose of extending the said guide arms
the same being fixed inany desired position by means of a set screw i.
Το
This rod terminates in a fork , on which a bracket l, pivotally connected to a
support m and provided with two clips or couplings n, is enabled to move.
these couplings the cycle or the steering tube o and the lower frame-stay are so
fixed that the wheel is prevented from falling down. The couplings with their
bracket must beso connected to the wheel that the support m occupies a vertical
position.
By this constructional arrangement and its vertical position it is possible for the
cycle to describe circles and curves of larger or smaller radii, without the rider
being impeded in his free movements. In order to increase the stability of the
guide-arm srelatively to each other, they may be connected to each other by stays p,
so as to form a completely rigid whole which cannot be easily deformed. The
guide arms may, according to their length, be arranged in a greater number upon
the rotary disc each of the additional guide arms being then also provided with an
additional cycle, and the arms fitted with movable couplings. Now in order that
wo cycles may be placed side by side and to render then movable to and fro in any
direction, a second fork radially extending from the end of the guide arm, is provided,
which is of course likewise fitted with couplings and bracket connected by suitable
ins. Both riders are then enabled to ride in any direction they like, within the
imits of the guide arms, without the risk of falling down; the stronger rider being
bus enabled to support the weaker according to requirement, since the latter, on
sing the inner cycle which traverses a smaller circle than the outer cycle, is carried
long with the outside-rider.

page_text: In order to prevent a pair of cycles from approaching each other as they move
along, it is preferable to provide the guide arm with an appropriate support.
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
An improved cycle-roundabout, the characteristic features of which are: a ring or
disc d rotatably arranged around a supporting column a, the said ring or disc being
provided with any suitable number of guide arms adjustable in their longitudinal
direction, and on the free extremities of which guide arms one or several brackets
are arranged, to which latter one or several cycles can be jointly connected by a
movable coupling.
