PROVISIONAL DE MOITIATION
Improvements in Treadle-driving Gear for Velocipedes and like
Vehicles, also applicable to Treadle-driven Machines.
We, CHRISTIAN HINRICH JACOB STOLDT, Gentleman, of 78, Schulterblatt, and
HEINRICH GUSTAV FRIEDRICHI BOCKMANN, Printer, of 108, Schulterblatt, both of
Hamburg, in the Empire of Germany, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to treadle driving mechanism for velocipedes and
machines of the kind in which the movement is effected by an up and down
motion of the feet,
The said mechanism has heretofore consisted for each foot, of a stationary
supporting pivot and a treadle lever arranged independently of said supporting
pivot.
The arrangement of the stationary supporting pivot enables the cyclist to stand
upright and to thus utilize the weight of his body, which is impossible in the case
where treadle levers without such supporting pivots are used.
This arrangement of supporting pivots and treadle levers, according to this
invention is so modified, that to the free extremity of each treadle lever a treadle
is pivotally connected, one end of which. is adapted to rest upon the stationary
supporting pivot. The rider's foot can, under these conditions be so placed upon
the treadle, that the toes rest directly upon or in close proximity to the supporting
pivot and the heel upon the opposite end of the treadle.
Thus, the toes receive a limiting stationary support, whilst by lifting and lower-
ing the heel, the pedal lever can be moved, in this operation the supporting pivot
simultaneously prevents the lever from being depressed beyond a certain limit.
The rider therefore need not endeavour to transmit the weight of his body by
means of his toes to the treadle and need not fear lest the pedal levers should
become too heavily weighted by his heels. He is enabled to freely distribute the
weight of his body upon his toes and heels without the treadle levers descending
beyond the admissible bottom limit, whereas in the case of former diving gear
of this kind a rather considerable proportion of the weight of the body must
always be supported by the toes, in order to enable the rider to maintain an
upright position upon the machine.
The transmission of motion from the foot driving gear to the driving wheel
may be obtained in any suitable manner.
The above described driving gear may be also utilized for driving treadle
operated machines.

We, CHRISTIAN HINRICH JACOB STOLDT, Gentleman, of 78, Schulterblatt, and
HEINRICII GUSTAV FRIEDRICH BOCKMANN, Printer, of 108, Schulterblatt, both of
Hamburg, in the Empire of Germany, do hereby declare the nature of this inven-
tion 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 treadle driving mechanism for velocipedes and
machines of the kind in which the movement is effected by an up and down
motion of the feet.
The said invention is illustrated in the accompanying drawing in which is
shown a side elevation of a bicycle provided with our improved driving gear.
a indicates the pedal levers each of which is pivotally connected at one end
to the axle of the rear wheel and at the opposite end provided with a pedal a¹
pivotally connected to the said pedal lever. Below the said pedals are arranged
rigid supporting surfaces 6 such as shoulders, pivots or the like provided on the
frame of the machine, the object of such supporting surfaces being to prevent
the pedals or pedal levers respectively from moving downward beyond a pre-
determined limit.
c designate traction chains, cords or the like each being attached at one end in
any suitable manner to a sleeve d on the pedal lever a, the said sleeve being made
adjustable thereon for the purpose of altering the leverage of the said pedal lever
as desired. The said traction chain, cord or the like passes over a guide pulley
fixed to the frame of the machine and is connected to its opposite end to a drum
on the axle of the driving wheel.
The pedal lever a instead of being pivoted to the axle of the driving wheel may
be pivoted to the frame at or near the point usually occupied by the crank axle of
a bicycle, and to this pedal lever may be rigidly attached a wheel segment to
which one end of the traction chain, rope or band is secured, the other end being
attached to the drum on the driving wheel axle as above described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. In treadle driving mechanism the combination of an oscillating pedal lever,
a pedal pivoted thereto and stop devices or supporting means provided at the
frame of the machine and adapted to limit the downward movement of the said
pedal and pedal lever, substantially as described.
2. The combination with a treadle driving mechanism of the kind described in
Claim 1, of means for connecting the said pedal lever to the axle or shaft to be
driven so as to transmit the movement of the said lever direct or indirect to the
shaft to be driven, substantially as described.
