Description
<EMI ID=1.1>
<EMI ID=2.1>
changement de vitesse destiné aux véhicules entraînés au
moyen d'une pénale, et dans lequel le moyeu d'un pignon

disposés sur le moyeu de la roue, avec la partie extérieure,
<EMI ID=4.1>
La caractéristique particulière de ce changement de
vitesse consiste dans le fait que l'axe de la pédale est
disposé en dehors de l'axe de la roue et que le moyeu du

D'après les fig.l à 4 , les deux bras de la fourche du châssis 1 de la roue arrière,dont il n' a été représenté qu' un bras 2 , sont entretoisés par une pièce vissée 3 et par

Cette plaque porte l'axe de pivotement d'un secteur 15 à l'intérieur duquel a été introduit à la presse un anneau 16 à l'intérieur duquel le moyeu de la roue le ou du pignon à chaîne 18 est monté au moyen d'un roulement à billes 17 à deux rangées de billes .

<EMI ID = 2.1>
gear change intended for vehicles trained in
means of a penal, and in which the hub of a pinion
<EMI ID = 3.1>
fully engaged, by means of locking pawls
arranged on the hub of the wheel, with the outer part,
<EMI ID = 4.1>
The special feature of this change of
speed consists in the fact that the axis of the pedal is
placed outside the wheel axle and that the hub of the

certain quantity, this sector being guided in a sector
fixed to the frame and the periphery of the sector being connected

placed in the position shown in dotted lines. La, fig.7 is a view of the chain sprocket from the inside. Fig.8 is a side view of the wheel hub provided with locking pawls.
According to fig.l to 4, the two arms of the fork of the frame 1 of the rear wheel, of which only one arm 2 has been shown, are braced by a screwed part 3 and by
