Improvements in or connected with Cycles.
I, JOHANN SCHOTT-TSCHETEN, citizen of the Town of Maripol in Maripol,
South Russia, do bereby 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 :-
My invention consists of a certain apparatus to be applied to cycles by means of
which the rider will be enabled to shift the centre of gravity of the machine in
order to adapt the same for roads of all descriptions, and to facilitate progress up
or down hills. In making use of the said apparatus the saddle will always
maintain a horizontal position and the rider will in consequence be enabled to sit
upright.
In order to give a clearer explanation of my said invention I have provided the
accompanying drawing, in which a bicycle is shown in the position of mounting an
incline, and furnished with the apparatus, which I will now proceed to describe.
The upper portion of the hollow rod or bar a, above the front fork, is surrounded
by a tubular rod b, threaded externally, but fitting loosely over the aforesaid
hollow rod or bar a allowing of free play between the two. The rod b is thus
capable of turning or revolving and is supported above and below on ball or anti-
friction bearings. On the upper end of the rod b is fixed a cog-wheel c which
engages with a cog-wheel c¹ fixed on the vertically placed spindle d. The threaded
rod 6 is further provided with a cylindrical matrix or screwed sleeve e, having two
rectangular projections, the ends of which are provided with sockets f, g for the
reception of the rods which connect the front and rear parts of the bicycle.
It will be seen that, by turning the threaded rod b in one direction or the other,
the matrix or sleeve e is raised or lowered thus adjusting the front wheel to different
heights.
The spindle d, with the cog-wheel e firmly attached, has a bearing in an arm h,
the latter being attached to the rod a by means of a clamp h', and carries at its
upper end a bevel wheel i, which engages with a bevel wheel it, the latter being
turnable, in either direction, by a crank k, their common axle being supported by
an arm projecting from the aforesaid arm h. The arm also gives support to
the upper end of the spindle d by means of a cross piece m. The rod b and matrix
or sleeve e are covered by a protecting outer tube o, which can be secured by
means of screw.nuts n.
The
While the machine is running on level ground the matrix e, with attachments, is
situated in the middle of the threaded rod b. In going up hill, the crank k is
turned, causing the rod b also to turn by means of the wheels i ¹ and c c¹.
matrix or sleeve e is thus moved downwards until the top of the saddle assumes a
horizontal position. In going down hill, the movement is reversed so that the
crank k is turned in the opposite direction and the matrix or sleeve e is raised
instead of lowered.
As the action takes place between the handle bars p, it is possible for the rider
to make the necessary adjustment without dismounting.
The adjusting apparatus can be detached, when desired, by removing the
clamp h, without injuring the appearance or efficiency of the machine.

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
The apparatus consisting of a threaded rod 6 with sleeve or matrix e capable of
being turned by means of geared wheels i i¹ and c c actuated by a crank k to be
applied to the front portion of a velocipede substantially as and for the purpose
hereinbefore described with reference to the accompanying drawing.
Dated this 28th day of September 1896.
