Improvements in or relating to the Propulsion of Road Vehicles.
We, WILHELM ULLRICH, of Rammlerstrasse 6, Berlin, Distillery Technician,
and FRANZ BIESECKE, of Rankestrasse 19, Berlin, in the Empire of Germany,
Inn Keeper, 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 a mechanically moved carriage in which the propelling
force is provided by the weight of the persons seated thereon and in which the
reciprocal effect of this force is produced by displacing the centre of gravity of
their bodies. This carriage consists essentially of a seat which is suspended to
swing round a turning point and revolves on both sides, spindles provided with
Archimedian screws by means of corresponding screw boxes and thus operates the
wheels of the carriage by means of a wheel gearing.
In the annexed drawing,
Fig. 1 is a side view of the carriage.
Fig. 2 a front view.
Fig. 3 a plan view, and,
Fig. 4 a section on line - of Fig. 1.
The manner of carrying out the system of propulsion is best seen from Fig. 4.
The seat a is supported upon 4 columns b, which stand upon a rectangular plate c
lying obliquely to the direction of the movement of the carriage. This plate
swings round the axle e supported in the bearing d and by displacing the centre
of gravity of the person sitting on the seat a allows an oscillating movement of
the latter round the axle e. The transmission of this movement into a turning
one of the spindles provided with Archimedian screws, is effected in the following
manner. The plate d embraces the latter loosely and lifts at its swinging move-
ment a plate which vertically guided in the rails 9 is connected solidly with
the under part i of a tooth coupling: 4 and i embrace loosely the spindles whilst
the upper part of the tooth coupling is provided with a female screw for
engaging the screw threads on the spindles. When by the movement of the person
sitting on the seat a the plate d is lifted on one side a coupling takes place
between i and k, the spindle is then turned whilst at the down movement of the
plate e the upper coupling part k slides loosely over the under part and does not
effect a rotation of the spindle, but at this moment the spindle flying on the other
side is turned. By means of the bevelled wheels fixed on the spindles these
operate the shaft n equally provided with bevelled wheels m, by which shaft the
chain wheel g and the shaft g of the back wheels rare turned by means of
the chain wheel o and the chain p. The transmission between the spindles f and
the shaft n, as well as between the latter and the shaft q may be effected in any
other manner. The carriage is steered by means of the known steering handle's
and the movable front wheel t. °
As will be seen from this arrangement the propelling of the carriage requires
small muscular force since the weight of the person sitting thereon and moving
to and fro is the sole cause of its uninterrupted movement.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed we declare that what
we claim is:-
A mechanically moved vehicle having a seat a adapted to swing round an axle e

means of screw boxes k on both sides, screw spindles f, these screw spindles f
moving by means of bevelled wheels.l.m or other transmission, the shaft n and from
this the wheels by means of chain or other gears.
Dated this 10th day of June 1896.
