COMPLETE SPECIFICATION.
A New or Improved Screen for the Protection of Cyclists against
Wind, Insects, and the like.
I, AUGUST ASSMANN, of 46, Freiburgerstrasse, Breslau, in the Empire of Ger-
many, Hotel Proprietor, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
ained in and by the following statement:-
This invention relates to a wind screen for cycles which may be arranged either
between the rider and the handle-bar or in front of this latter thereby con-
stituting an efficient protection against wind, insects, and so forth.
This screen is manipulated in an exceedingly simple manner similar to that
employed in the case of an umbrella; closing is effected by releasing a rod, whilst
when it is desired to open the screen this rod is raised and secured.
Owing to the forwardly pointed or wedge-like form which is given to the screen
same divides the wind and offers a minimum of resistance.
The invention is illustrated in the accompanying drawing in which:
Fig. 1 shows the screen in a folded or closed condition.
Figs. 2 and 2 illustrate it in an extended or open condition.
Fig. 2b is a longitudinal section on line A B of Fig. 2
Fig. 3 is a plan view of the screen when open as seen from above.
Fig. 4 is a reproduction of a portion of Fig. 1 upon a larger scale.
Fig. 5 is a reproduction of a portion of Fig. 2 upon a larger scale, and
Fig. 6 shows the screen extended and mounted upon a bicycle
Upon the screen support a which is vertically fixed upon the cycle several pairs
of ribs (advantageously wire ribs) b b are pivotally arranged symmetrically with
the axis of the said support these ribs being jointed to the vertical rod d by
means of pairs of pivotally arranged links c in such a manner that when the rod d
is raised the ribs b and the material fixed to them by means of eyes are extended
and assume the position illustrated in Figs. 2, 2, 2, 3 and 5.
Small links e (Fig. 5) may be jointed upon the links c and upon the rod d
serve to strengthen the device.
In order that the jointed parts b c d e may be securely guided and kept in
position-a guide link f is pivoted upon the upper end of the rod d and upon
the screen support a.
If the thimble or sleeve g is released from the spring catch g' and then the
rod d raised the ribs b b and the material fastened thereto are extended by means
of the ribs c c and the rod d is clamped or fixed by a suitable retaining device on
the support a, ask for example (Figs. 2 and 2b).
In order that the rider may have an unimpeded view of his surroundings
there is arranged upon each side of the screen support and in proximity thereto
a longitudinal strip of gauze or other suitable material forming an insertion
in the material of which the screen itself is composed.
When the screen is not required for use it is dismounted from the position
shown in Fig. 6 and may be packed in a cover or sheath and suspended horizontally
between the rider and the handle-bar

page_text: 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. A wind screen for cycles consisting of the arrangement and combination of
a screen support a adapted to be fixed vertically upon the cycle, pairs of wire
ribs bb hinged to the said support a and carrying the screen material thereon
and links cc pivotally connected to said ribs and to the operating rod d in such
a manner that by raising this rod d the ribs bb and the screen material fixed
thereto are extended and the screen opened substantially as and for the purposes
set forth.
2. A wind screen for cycles constructed combined and arranged to act in com-
bination with and arranged upon a cycle substantially as and for the purposes
set forth.
