   Beim   Niedergehen   des Fahrstuhles kehrt der Kurbelzapfen r infolge der in entgegengesetzter Richtung sich vollzichenden Drehung der Trommelwelle   w   in seine Ausgangsstellung r'zurück und rückt in gleicher Weise auch an dieser Hubgrenze den Stromschalter aus. 



   PATENT-ANSPRÜCHE : i.   Endausschalter   für elektrisch betriebene Aufzüge, dessen Betätigung durch ein Triebrad erfolgt, welches an den Hubenden von der Trommelwelle   (ici)   mitgenommen wird, dadurch gekennzeichnet, dass ein auf der Trommelwelle   (ici)   sitzendes Ritzel (o) zwei lose auf der Achse des Stellrades (n) des Schalters sitzende Zahnräder (a, b) betätigt, von welchen eines (a) eine geringere Zähnezahl besitzt als das zweite (b) und einen verschiebbaren Mitnehmer (s) trägt,

 EMI2.1
 



   When the elevator descends, the crank pin r returns to its starting position r 'as a result of the complete rotation of the drum shaft w in the opposite direction and in the same way also disengages the current switch at this stroke limit.



   PATENT CLAIMS: i. Limit switch for electrically operated elevators, which is actuated by a drive wheel which is taken along at the ends of the stroke by the drum shaft (ici), characterized in that a pinion (o) sitting on the drum shaft (ici) has two loosely attached to the axis of the adjusting wheel ( n) the switch actuates gears (a, b), one of which (a) has a smaller number of teeth than the second (b) and carries a movable driver (s),
