DESCRIPTION DE L'OBJET INVENTE
La pièce inventée désignée sous le nom de "Multiplicateur" se compose de trois pièces :
1 ) le plateau à roulement n ) la manivelle avec pignon de commande
3 ) la roue dentée
Le plateau à roulement est fixé hors centre du braquet, et peut avoir n'importe quelles dimensions.
La manivelle avec pignon de commande entraine la roue dentée qui est fixée sur le plateau de roulement.
Le plateau de roulement avec libre choix du nombre de dents fonctionne avec chaîne ou peut fonctionner avec des pignons,à l'endroit ou le pignon de commande s'emboite.
(voir plan n 3)
La manivelle avec pignon de commande est de 2 à 3 cm hors centre avec le centre du plateau c'est à dire l'appareil.
La roue dentée qui commande la roue arrière est fixée sur le plateau au moyen de rivets,boulons ou autres pièces.(voir plan n 4)
L'appareil inventé est fixé au cadre par la cuvette et une attache au libre choix.
En résumé,l'appareil multiplicateur n'est pas au .centre du plateau et se déplace dans un cercle de plusieurs centimètres dans n'importe quelle direction et n'est pas fixé au plateau roue dentée,c'est à dire que le plateau avec roue dentée de la commande arrière est hors centre du braquet pédalier.

From Greef @
DESCRIPTION OF THE OBJECT INVENTED
The invented piece referred to as the "Multiplier" consists of three pieces:
1) the bearing plate n) the crank with control pinion
3) the toothed wheel
The bearing plate is fixed off the center of the gear, and can have any dimensions.
The crank with control pinion drives the toothed wheel which is fixed on the bearing plate.
The bearing plate with free choice of the number of teeth works with chain or can work with pinions, at the place where the drive pinion fits.
(see plan n 3)
The crank with control pinion is 2 to 3 cm off center with the center of the chainring ie the device.
The toothed wheel which controls the rear wheel is fixed to the plate by means of rivets, bolts or other parts (see drawing n 4).
The invented device is fixed to the frame by the bowl and a clip of your choice.
In summary, the multiplier apparatus is not in the center of the chainring and moves in a circle of several centimeters in any direction and is not fixed to the cogwheel chainring, i.e. the chainring with the rear control cogwheel is out of the center of the bottom bracket.
