  DEMULTIPLICATION DU PEDALIER POUR VELOS ET ANALOGUES. 



   COTE   DROIT.   



   A. Levier droit (1) muni à son extrémité avant d'une pédale or- dinaire de vélo (2) au milieu se trouve un roulement conique régable (3) fixé sur, le pivot de la biellette   (4)   provenant du pédalier ordinaire du vélo muni de son pignon denté (n  5). 



   Ce levier droit   a,   à son extrémité   postérieureun   tube '(6) relié par un dispositif de torsion (7) passant entre deux poulies à gorge 8A et 8B montées sur roulements   billes   coniques et   régables.   



   B. Les deux poulies à gorge 8A - 8B sont fixées (l'une 8B à un secteur mobile (9) relié par la poulie à gorge 8A à un secteur inerte (10) fixé à l'arrière du cadre proprement dit du vélo. 



   A l'axe de la poulie- à gorge 8A est enroulé un ressort pour le rappel vers l'avant de la poulie 8B par le secteur (9). 



   COTE   GAUCHE   
Même levier que pour le côté droit fixé par les mêmes pièces à l'exception du pignon denté (5). 



   L'appareil faisant l'objet des plans et dénommé "P E D A L I E R   " R E G   L 0 " se place sur le bras de pédale du pédalier ordinaire de vélo. 



   A l'arrière du vélo se trouve le dispositif d'appuis pour le tube prolongeant le bras de l'appareil étant fixé sur le pédalier ordinaire. 



   Il se compose d'un bras droit muni d'une pédale ordinaire et à ce bras est fixé un tube à torsion passant entre deux poulies   à   gorge dont l'une est mobile et est rappelée vers l'avant par un ressort obligeant ain- si le tube à rester dans la gorge et y adhérero (Se).A.H.

  MULTIPLICATION OF THE CRANKSET FOR BIKES AND ANALOGUES.



   RIGHT SIDE.



   A. Right lever (1) fitted at its front end with an ordinary bicycle pedal (2) in the middle there is an adjustable conical bearing (3) fixed on, the pivot of the connecting rod (4) coming from the ordinary crankset of the bicycle fitted with its toothed pinion (n 5).



   This right lever has, at its rear end a tube '(6) connected by a torsion device (7) passing between two grooved pulleys 8A and 8B mounted on tapered and adjustable ball bearings.



   B. The two grooved pulleys 8A - 8B are fixed (one 8B to a movable sector (9) connected by the grooved pulley 8A to an inert sector (10) fixed to the rear of the frame itself of the bicycle.



   At the axis of the pulley-groove 8A is wound a spring for the forward return of the pulley 8B by the sector (9).



   LEFT SIDE
Same lever as for the right side fixed by the same parts except the toothed pinion (5).



   The device which is the subject of the plans and called "P E D A L I E R" R E G L 0 "is placed on the pedal arm of the ordinary bicycle crankset.



   At the rear of the bike is the support device for the tube extending the arm of the device being fixed on the ordinary crankset.



   It consists of a straight arm fitted with an ordinary pedal and to this arm is fixed a torsion tube passing between two grooved pulleys, one of which is movable and is returned to the front by a forceful spring thus the tube to stay in the throat and adhere to it o (Se) .AH JAMART. in appendix 3 drawings
