An Apparatus applicable to Velocipedes for Reducing the
Resistance of the Air.
I, JOHANN SCHANNEN, Jr., Bank Manager, of 186, Marktplatz, Perjamos,
Hungary, 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:-
Cycling whilst it has its decided advantages, such as the strengthening of the
body and the promotion of the general health, has also its disadvantages. Among
the latter the first to be considered is the fact that the cyclist, on account of the
great resistance of the air, has to bend his body forward when he desires to attain
great speed. This bending of the body has a bad effect on the human organism.
Equally detrimental is the fast that breathing is rendered more difficult by quick
cycling and this, according to the opinion of medical men, is apt to produce
diseases of the lungs and the heart. However, these disadvantages can easily be
avoided by making use of my invention the object of which is the production
of an air-cutting apparatus capable of being adapted to velocipedes of any
description.
The annexed drawings show, by way of example, one mode of carrying out the
invention.
Fig. 1 is a perspective view of the apparatus.
Fig. 2 is a front view of a clamp used for fitting up the air-cutter.
Fig. 3 shows a detail of the clamp.
The apparatus consists of two sides a, a, which can be fitted up and of a cover b
which can also be fitted up. The sides a meet together, wedge-wise, at the front
and are able to turn on the common axle c so that they can be opened out more
or less as desired.
To enable the sides to be opened or closed, more or less as desired, they are
provided, at top and bottom, with adjusting mechanism consisting of arms d, d,
jointed to the sides and by means of a clamping screw, common to both, to the
bar e which latter is pivotted on the axle c and is also provided with a longitudinal
slot el. By moving the clamping screw along the slot e¹ the inner ends of the
arms & connected to the screw are also moved so as to open or close the sides as
will be readily understood. By tightening up the screw the arms d and sides
can be locked in position.
By means of the adjusting mechanism the sides are connected with a vertical
bar which is arranged along the line of the centre of gravity of the apparatus.
The sides consist of plates of celluloid, which are always transparent, in
addition to the frames represented on the drawing. The celluloid plates may
be fastened to the frames by means of cords which are drawn through holes in
them or in any other manner. The transparent celluloid plates are not shown
on the drawings.
The cover which consists of silk or thin linen stretched over the rod b, as
