  CHANGEMENT de   VITESSES   POUR   CYCLES. SYSTEME   "HOSAY"  @   DESCRIPTION Un axe sur lequel est fixé les pédales est grossi en A,et reçoit quatre encoches pour loger des petits cliquets 1,poussé vers l'extérieur par un petit   ressort,c'est   cliquets,à part un cha- que quart de tour, sont retenus dans leur logement par une bague spé ciale K,sur laquelle tournent folle 4 roues dentées extérieures, H,G,F.E. et en contact permanent avec des roues   intérieures,H'G'F'   Et;

  Il suffit d'un rétropédalage pour provoquer le changement de vi- tesse,un quart de tour en arrière donne un autre vitesse.La prise directe n'est pas purement des engrenages mais bien une fourche E, attaquant un tourillon E,cette fourche tourne donc folle sur la bague K,quand elle n'est pas en contact,c'est à dire pas en prise. 



  La roue porte chaîne D,peut être indépendante,c'est à dire amovible   cette roue porte chaîne est excentrée par rapportRà l'axe du pédalier,et tourne sur un axe dont roulement à billes porté par la piè-   ce 0,Le   cuir   de fermeture peut être remplacé par un second palier   à roulement à billes,ce qui supprime le porte à faux cette applica tion sera nécessaire dans les vél#de touristme,là où on ne regarde   pas au poids ni au gabarit. 



  Tout l'appareil étant complètement fermé,il pourra être   constanment   lubrifier.La pièce C,remplace la cuvette actuelle. 



  Ce dessin ne donnant que le principe de fonctionnement n'est pas ex xécuté comme il devra l'être réellement,au point de vue légèreté,am minoisent des pièces etc..

  CHANGING SPEEDS FOR CYCLES. "HOSAY" SYSTEM @ DESCRIPTION An axis on which the pedals are fixed is enlarged in A, and receives four notches to accommodate small pawls 1, pushed outwards by a small spring, it is pawls, apart from a cha- only quarter turn, are retained in their housing by a special ring K, on which 4 external toothed wheels rotate, H, G, FE and in permanent contact with internal wheels, H'G'F 'Et;

  A back-pedaling is enough to cause the gear change, a quarter of a turn back gives another speed.The direct drive is not purely gears but a fork E, attacking a journal E, this fork turns therefore crazy on the K ring, when it is not in contact, ie not in engagement.



  The chain wheel D, can be independent, that is to say removable this chain wheel is eccentric with respect to the axis of the crankset, and turns on an axis whose ball bearing carried by part 0, The leather of closure can be replaced by a second ball bearing, which eliminates the overhang this application will be necessary in tourist bikes, where no consideration is given to weight or size.



  As the whole device is completely closed, it can be constantly lubricated. Part C, replaces the current bowl.



  This drawing, giving only the operating principle, is not executed as it should actually be, from the point of view of lightness, the appearance of parts, etc.

** ATTENTION ** end of DESC field can contain start of CLMS **.
