PROVISIONAL SPECIFICATION.
Improvements in Motors Operated by Human Power.
I, PHILIPPE BALDENSPERGER, of 95 Boulevard Beaumarchais, Paris in the
Republic of France, Gentleman do hereby declare the nature of this invention to
be as follows :—
This motor offers various important advantages over similar mechanisms hitherto
devised such as facility of construction, simplicity and consequently an increased
working capacity.
My chief object as before stated has been to avoid complicated machinery which
would only render the motor more expensive while diminishing its working capacity.
Upon a support having two vertical side frames is mounted a horizontal shaft to
which is rigidly attached a ratchet-wheel operated by two pawls mounted
respectively upon two arms vibrating on the shaft and operated alternately by links
secured to the ends of the said arms and to the ends of a lover swinging upon a fixed
pivot projecting from an arm integral with the frame.
The operator of the motor takes up his position upon a saddle swinging upon its
pivot or fulcrum in which suitable provision is made for reducing friction. The
feet of the operator rest upon plates secured to the arm of each frame. He then
pulls and pushes alternately by hand the handle or knob terminating the lover.
This movement imparts motion to the ratchet wheel through the medium of one or
the other of the pair of pawls as the case may be. The motion produced by the
displacement or swinging of the body of the operator upon the saddle is utilized to
assist the conveyance of motive power produced by his operating the handle the
Oscillation of the saddle in each of the two directions alternately being transmitted
to the lever by an arm and a link.
By this means each displacement of the centre of gravity of the operator's body
upon the saddle is made serviceable to lighten the strain he has to exercise and
render it more effective the greater part of the forces which have hitherto generally
been lost or absorbed by the fulcrums being thus recovered.
This apparatus enables motive power to be supplied to stationary or portable
engines and machines of all kinds such as tool-machines in small factories, tricycles,
screw-boats sleighs and the like.

COMPLETE SPECIFICATION.
Improvements in Motors Operated by Human Power.
I, PHILIPPE BALDENSPERGER, of 95 Boulevard Beaumarchais, Paris, in the
Republic of France, 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 motor offers various important advantages over similar mechanisms hitherto
devised, such as facility of construction, simplicity, and consequently an increased
working capacity.
The invention will be best understood by reference to the accompanying drawings

page_text: My chief object as before stated, has been to avoid complicated machinery which
would only render the motor more expensive while diminishing its working capacity.
Upon a support having two vertical side frames S is mounted a horizontal shaft O
to which is rigidly attached a ratchet-wheel R operated by two pawls K K' mounted
respectively upon two cranks B B' turning on the shaft Ŏ and operated alternately
by links c c secured to the ends m m¹ of the said cranks and to the end of a
lever a swinging upon a fixed pivot h supported in projecting arms D which may be
integral with the frames S. Pedals may also be arranged upon the lever a so that
the motor may also be operated by the feet.
The operator of the motor takes up his position upon a saddle A swinging upon
its pivot or fulcrum E on which suitable provision is made for reducing friction.
The feet of the operator rest upon the plates P secured to the arm D of each
frame S. He then alternately pulls and pushes by hand the handle M at the upper
end of the lever a. This movement imparts motion to the ratchet wheel R through
the medium of one or the other of the pawls K K' as the case may be. The motion
produced by the displacement or swinging of the body of the operator upon the
saddle A is utilized to assist the conveyance of motive power produced by his
operating the handle M the oscillation of the saddle in each of the two directions
alternately being transmitted to the lever a by an arm E F and a link b g.
By this means each displacement of the centre of gravity of the operator's body:
upon the saddle is made serviceable to lighten the strain he has to exercise and
render it more effective, the greater part of the forces which have hitherto
generally been lost or absorbed by the fulcrums being thus recovered and
utilized.
This apparatus enables motive power to be supplied to stationary or portable
engines and machines of all kinds such as machine-tools in small factories, tricycles,
screw-boats, sleighs, or sledges, and the like in which last named application toothed
wheels may be employed so that they may alternately engage with or grip the
surface of the ice and cause the runners to slide onwards.
Having now particularly described and ascertained the nature of the said inven- 3
tion and in what manner the same is to be performed, I declare that what I
claim is,-
1. In a motor adapted to be operated by human power the employment of a shaft
on which is rigidly mounted a ratchet wheel to be operated alternately by one of
two pawls attached to arms which are mounted upon the same shaft and are in their 3
turn operated both by one lever upon which the operator acts (by his hands or feet)
and through the saddle which is mounted upon a pivot substantially as described
and illustrated in the accompanying drawings.
2. The combination with a sledge or the like of a motor substantially as
described and toothed wheels operated thereby and the teeth of which are
intermittently set in such a manner as to alternately engage with or grip the
surface of the ice or the like and thereby cause the runners to move on.
3. The combination and arrangement of parts constituting the complete motor
substantially as described and illustrated in the accompanying drawings.
