PROVISIONAL SPECIFICATION
Improvements in Driving Mechanism for Velocipedes and other
Road Vehicles.
EMIL FRANZ ENDEMANN, Manufacturer, at Hamburg, Neustädter Neustrasse 18,
Germany, do hereby declare the nature of this invention to be as follows:-
The object of the present invention is a driving-mechanism, for vehicles,
requiring but little driving-power, thus fitted for conveying, especially heavy
loads.
The annexed drawing represents a perspective view of the driving mechanism
of such a vehicle, driven and conducted by a single person. It is indifferent
whether the guiding-wheel is fitted in front or behind the body of the vehicle;
The boay of the vehicle may also be replaced by seats for several persons.
Likewise, instead of a three-wheeled frame, a four-wheeled one may be chosen,
one axle thereof being shaped as a sliding-axle; in either case the driving-mechan-
ism remains the same.
In the following description of the mechanism only the side of the driving-
gear next to the viewer will be described, the other, one, transposed by about 180°
being analogous to the former.
To the coupling-box of the frame-tube is fitted the lever c its fore-end con-
stituting the pedal c¹. The bar d transmits the movement of the lever c to the
end of the double lever e pivoted on a corresponding tube socket f of the saddle
supporting tube g. By means of the bar h is effected the transmission of power
from the lever-arm to the angle-lever i also pivoted independently of c to the
coupling-box b. From the angle-lever the bar j transmits the motion to the
crank of the shaft, from whence the rotation is then effected upon the hind-
wheel axle by means of toothed-wheels and chains m, m¹. The fly-wheel n fitted
to the crank-shaft is for balancing the rotatory-movement.
It is true that with a normal movement of the legs the advance of the tricycle
will be reduced; but on the other hand the driver of the vehicle will have to make
the less effort the longer the lever-end c¹. At the same time, however, it is to be
recommended, that the paths of the pedals, when swinging, be but short; when a
quicker movement of the legs is rendered possible, the whole vehicle thus of course
advancing quicker.

in Germany, do hereby declare the nature of this invention and in what manner
[Price 8d.]

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of the present invention is a driving-mechanism, for vehicles,
requiring but little driving-power, thus being fitted for conveying, especially heavy
loads.
The drawing, filed with Provisional Specification, represents a perspective view
of the driving mechanism of such a vehicle, driven and conducted by a single
person. It is indifferent, whether the guiding-wheel is fitted in front or behind
the body of the vehicle.
The body of the vehicle may also be replaced by seats for several persons.
Likewise, instead of a three-wheeled frame, a four-wheeled one ay be chosen,
one axle thereof being shaped as a sliding-axle; in either case the driving-mechan-
ism remains the same.
In the following description of the mechanism only the side of the driving-
gear next to the viewer will be described, the other one, transposed by about 180°
being analogous to the former. To the coupling-box b of the frame-tube a is fitted
the lever c with the pedal c¹, connected with its front-end. The bar d transfers
the movement of the lever c on the end of the double lever e, pivoted on or of the
corresponding tube-sockets f of the supporting-tube g of the saddle. By means
of the bar is effected the transmission of power from the lever arm on the
angle-lever, also pivoted independently of c to the coupling-box b. From the
angle-lever the bar j transmits the motion to the crank k of the saft from
whence the transmission is then effected upon the hind-wheel-axle by means of
toothed-wheels and chains m, m'. The fly-wheel h fitted to the crank-shaft is
destined for balancing the rotatory movement.
It is true that with a normal movement of the legs the advance of the tricycle
will be reduced; but on the other hand the driver of the vehicle will have to make
the less effort the longer the lever-arm c. At the same time, however, it is to be
recommended, that the paths of the pedals, when swinging, be but short; when a
quicker movement of the legs is rendered possible, the whole vehicle thus of course
advancing quicker.
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:
A driving-mechanism for vehicles worked by a crank-gear and levers, together
with a fly wheel, substantially as described and set forth.
