Improvements in Driving Mechanism for Road Vehicles
I, CHARLES CADFRSKI, of 9 Rue Varecka, Warsaw, in the Empire of Russia,
Consulting Engineer, at present residing at Rue Chomond, Paris, in the
Republic of France, do hereby declare the nature of this invention to be as
follows
-
The object of this invention is to utilize the weight of persons or of lifeless
bodies in combination with a screw as the fundamental mechanism for setting in
movement road vehicles of any kind The intermediate mechanism which I employ
for utilizing the motive power is simply a screw and it is the use of this screw,
sei ving directly or indirectly to set the vehicle in movement, which constitutes the
characteristic feature of this invention I may give to the screw any suitable
position for its utilization namely for the setting in motion of vehicles, in which the
weight of living beings or of lifeless bodies serves as the motor
I term vehicles constructed on this principle "Barocinette
the Greek and signifies "weight as motor
"
"which is taken from
The motive weight is here supposed to be that of a man It acts upon a screw,
and the rotary movement of this screw is transmitted to the axis of the rear wheels
of the vehicle by means of two groups of bevel wheels and of a pair of cylindrical
wheels, which latter are connected by an endless chun The said screw is actuatel
by a nut and can turn in one direction only At each side of the screw are the
guiding rods During the movement, the nut becomes in its action dependent upon
the seat, guided by the aforesaid rods and by its descending movement forces the
SCIew to turn The rider rises again with the seat from the low position into the
high position by the aid of springs carried by the guide rods, and by the aid of a
pedal and of a lever The nut rises again while tuining under the influence of an
interioi sping which surrounds the screw A fly wheel keyed to the lower part of
the screw produces the acceleration of movement of the vehicle, subsequently
regulates this movement, and compensates for the power expended for lifting the
movable mechanism into the high position, it thus permits of an increase of speed
On starting, the action of the weight placed upon the seat, acts upon the screw of
very quick pitch and upon a determined height, for instance one or two decimeters,
which gives at once an initial speed of 4 metres (which space may be supposed to
be traversed in one second) The action of the weight, repeated each second and
combined with the moving masses, results in a uniformly accelerated movement,
after 25 seconds the speed will be able to attain to 12 meters per second, which
corresponds to a medium pace of 40 kilometers per hour This rate may still be
increased
For stopping the vehicle a brake, actuated by a pedal or hand lever acts upon the
fly-wheel A brake, acting upon one of the two rear wheels, or upon the front
wheel of the vehicle may be provided
In order to remain seated on stopping the vehicle the rider sets in action a
movable support, by means of a hand lever arranged at the side
In order to impart to the vehicle a retrograde movement, one of the bevel wheels
Is caused to engage with the wheel, mounted in front of another bevel wheel and
upon the same axis therewith This changing may for instance be produced by
displacing by the aid of a hand lever, the axis which is of such section that during
its displacement the chain wheel does not move

page_text: My vehicles may be constructed or adapted for carrying one or more persons of
more or less weight
Auxiliary or complementary arrangements are applied for the guidance for
increasing, lessening or modifying the speed of transmission-forward or backward-
or in a word for putting into practice in reasonable manner the principle of this
invention namely producing the movement of vehicles of any kind, light or heavy,
by the weight of living beings or lifeless bodie, acting upon a screw with one or
a number of threads utilized or applied in any position so as to transmit directly or
indirectly the movement upon the motor wheel on wheels of vehicles

I, CHARIIS CADERSKI of 9 Rue Varecka, Warsaw, in the Empire of Russia,
Consulting Engineer at present residing at 5 Rue Chomond, Paris, in the
Republic of France, do hereby declue 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 follow in statement
The object of this invention is to utilize the weight of persons or dead weights in
combination with a screw as the fundamental mechanism for setting in movement
road vehicles of any kind The intermediate mechanism which I employ for
utilising the motive power is simply a screw and it is the use of this screw, serving
directly or indirectly to set the vehicle in movement, which constitutes the
characteristic feature of this invention I may give to the screw any suitable
position for its utilization, namely for the setting in motion of vehicles, in which the
weight of living beings or a dead weight serve as the motor
I term vehicles constructed on this punciple "Barocinette which is taken
from the (Treek and signifies "weight as motor
In the example hereinafter given, the motive weight is supposed to be that of a
man It acts upon a screw, and the rotary movement of this screw is transmitted
to the axis of the rear wheels of the vehicle by means of group of bevel wheels
and of a pan of sprocket wheels, which latter are connected by an endless chain
The said screw is actuated by a nut so as to turn in one direction only The nut
is carried by a frame receiving vertical motion by the weight on the sent, being
guided by lateral guide rods, and by the descending movement of the nut it forces
the screw to turn The rider rises again with the seat from the low position into
the high position by the aid of springs carried by the guide rods, and by the aid of
a pedal and of a lever The nut in rising with the frame turns freely upon the
screw A fly wheel keyed to the lower part of the screw converts the successive
impulses into a uniform rotary motion which is imparted to the road wheels of the
vehicle through the before mentioned gearing
On starting, the action of the weight upon the seat, acts upon the screw of
very quick pitch through a certain height, for instance one or two decimeters,
which gives at once considerable initial speed, which is then accelerated by the
successive rising and falling motions of the rider, so that, by comparatively slight
exertion a considerable speed of travel can be attained
For stopping the vehicle a brake, actuated by a pedal on hand lever, acts upon
the fly-wheel A brake, acting upon one of the two rear wheels, or upon the front
wheel of the vehicle may also be provided
The gearing by which the motion of the screw 1 transmitted to the road wheels

page_text: Fig 4 a perspective view
The motor weight is in this case the rider, his seat is for this purpose carried by
a sliding frame e working with eyes e¹ on vertical guide bars in the fixed frame i,
and supported in the raised position by springs f mounted on the guide rods
In bearings in the fixed frame is mounted the vertical shaft a having one or
more quick screw threads formed on it, and upon this shaft is mounted a screw nut d
suitably carried by the sliding frame so as to rise and fall with it in such manner
that on the downward motion of the seat, and frame the nut is prevented from
rotating by a pawl or catch taking into ratchet teeth on the nut, while during the
ascent of the frame the nut is free to revolve Thus on the frame e being pressed
downward by the weight of the rider, the nut d will effect the rotation of the
shaft a, this carries near its lower end a bevil wheel b, geaning with a bevil
wheel 61, on the same shaft with which is a bevil pinion 2 On a shaft g are
mounted loose two other bevil wheels 63 and 6 gearing with opposite sides of the
pinion, and provided with suitable clutches whereby either the one or the other
can be made to impart its motion to the shaft On the latter is fixed a sprocket
wheel which is geared to a sprocket wheel c fixed on the axle of the road
wheels Thus the rotary motion imparted to the screw shift a by the nut dis
transmitted to the road wheels in one direction or the other according as the one or
other of the bevil wheels 68 or 64 is put in gear with shaft q Near its lower end
the screw shaft a carries a fly wheel 1, which stores up the momentum of the
successive impulses imparted to the shaft on the downward motion of the seat,
frame and nut, and thereby renders the motion a uniform continuous one which is
imparted to the road wheels
The eyes e¹ of the sliding frame are situated between the springs f that effect
the raising thereof, and counter springs f¹ that bear upon the cross piece of the
fixed frame 2, which act as elastic buffers to the frame as it rises and prevent
unpleasant shocks For assisting the upward motion of the seat and frame, a
pedal g is provided, which is connected by rod g¹ levers g² g³ rod 9* and lever go to
the sliding frame, so that when, after depressing the seat and frame, the rider rises
slightly, bearing with his feet on the pedal g, the said levers, in conjunction with
the springs will be made to raise the seat, fiame and nut into the raised position
Brake blocks are provided for acting on the rim of the fly wheel 2, for stopping
or slowing, such blocks being actuated in any suitable manner either by a treadle
or by a lever connected to the steering handle in the well known manner
If necessary a brake may be applied to the road wheels, either in lieu of the
brake blocks k, or in addition thereto
Although I have described my invention as applied to a tricycle by way of
example, it will be evident that it is equally applicable, with suitable modifications
to bicycles and other forms of velocipedes and self propelled vehicles

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is
-
1 Driving mechanism for a vehicle so arranged that the weight of the rider or
a dead weight is utilised to turn by its descent a screw suitably geared to the
driving wheels, substantially as described
2 A cycle provided with driving mechanism such as is above referred to,
worked by the weight of the rider, actuating a screw by means of a vertically
reciprocating screw nut, in combination with springs, pedals and levers for raising
the seat after its depression by the weight, substantially as described with reference
to the drawings
3 In driving mechanism for a vehicle, the combination of a screw spindle a
connected by gearing to the road wheels, 2 screw nut mounted on the screw spindle
and carried by a vertically sliding frame supporting the rider's seat, the said nut
being prevented from turning on the spindle in one direction while it is free to turn
in the other direction, and springs connected to the sliding frame for effecting its
ascent, with or without the assistance of a treadle action, substantially as described
