 EMI2.1 
 Theilen a3 versehen, welche das Abstellen der Maschine veranlassen, falls dem   Fordorkorb   in diesem Theile seiner Bewegung nicht eine allmählich abnehmende Geschwindigkeit ertheilt wird. 



   Um die Vorrichtung für verschiedene Fördergeschwindigkeiten (Material-oder   Personenförderung) stollon   zu können, ohne die Empfindlichkeit des Regulators c zu beeinträchtigen, sind an der Antriebswelle   A   der Vorrichtung zwei   Riemscheiben M   lose angeordnet, welche durch Riemen mit zwei gleich grossen Scheiben   m2 m2   der Regulatorantriebswelle m3 verbunden sind und vermittels der   Klauenkupplungen 1   und des Hebels x abwechselnd mit der Welle A   gekuppelt werden können.   Für Materialförderung wird beispielsweise die Kupplung l1, für Personenförderung die Kupplung   l   eingerückt. In beiden Fällen ist die Tourenzahl des Regulators c die gleiche. 



   PATENT-ANSPRÜCHE : 
1. Sicherheitsvorrichtung für Fördermaschinen, gekennzeichnet durch zwei miteinander verbundene Zahnstangen a a, welche durch einen Geschwindigkeitsregulator c parallel zu sich selbst zwei auf den beiden Signalschraubenspindeln f f fortbewegten Mitnehmern e1 e1 genähert oder von denselben entfernt werden, so dass bei einer eintretenden Überschreitung der zulässigen   Fördergeschwindigkeit   der jeweilig nach unten bewegte Mitnehmer el mit der ihm gegenüberstehenden Zahnstange a in Eingriff gelangt, dieselbe nach unten drückt und dadurch einen Hebel   9 auslöst,   welcher den   Dampfzntritt   zur Maschine absperrt und gleichzeitig die Dampfbremse bethätigt. 



   2. Bei einer Sicherheitsvorrichtung der unter 1 genannten Art die Anordnung von vorspringenden verzahnten Theilen   a3   an den dem Ausfahren des Förderkorbes ent- sprechenden Enden der Zahnstangen a a, zum Zwecke, die Maschine abzustellen, falls dem   Förderkorb   in diesem Theile seiner Bewegung nicht eine   allmählich     abnehmende     Geschwindigkeit ertheilt   wird,   bexw. das Überfahren der Hängebank hintanzuhalten.   



   3. Bei einer Sicherheitsvorrichtung der unter 1 genannten Art die Anordnung ver- schieden grosser, mit der Antriebswelle J kuppelbarer Antriebsscheiben   m     tel für   den
Regulator r, zum Zwecke, die Vorrichtung für verschiedene Fördergeschwindigkeiten stellen

 EMI2.1
 Provided parts a3 which cause the machine to be switched off, if the basket is not given a gradually decreasing speed in this part of its movement.



   In order to be able to use the device for different conveying speeds (material or people conveyance) without impairing the sensitivity of the regulator c, two belt pulleys M are loosely arranged on the drive shaft A of the device, which are connected by belts with two equally sized pulleys m2 m2 of the regulator drive shaft m3 are connected and can be alternately coupled to the shaft A by means of the claw couplings 1 and the lever x. For example, clutch l1 is engaged for material conveyance and clutch l is engaged for passenger conveyance. In both cases the number of revolutions of the regulator c is the same.



   PATENT CLAIMS:
1. Safety device for conveying machines, characterized by two interconnected racks aa, which by a speed regulator c parallel to itself two drivers e1 e1 moved on the two signal screw spindles ff are approached or removed from the same, so that when the permissible conveying speed is exceeded each downwardly moved driver el engages with the rack a opposite it, pushes the same downward and thereby triggers a lever 9 which blocks the steam access to the machine and at the same time actuates the steam brake.



   2. In a safety device of the type mentioned under 1, the arrangement of projecting toothed parts a3 at the ends of the toothed racks aa corresponding to the extension of the conveyor cage, for the purpose of stopping the machine if the conveyor cage does not gradually decrease in this part of its movement Speed is given, bexw. to prevent driving over the suspended bench.



   3. In a safety device of the type mentioned under 1, the arrangement of drive pulleys of different sizes, which can be coupled to the drive shaft J, for the
Regulator r, for the purpose of setting the device for different conveying speeds
