  Andrehkurbel mit Sicherung gegen Rückstoss. 



   Die Erfindung betrifft eine Andrehkurbel für Explosionskraft-, Transport-und Hebemaschinen und bezweckt einen beim Andrehen gegebenenfalls auftretenden Rückstoss für den die Kurbel Bedienenden unschädlich zu machen. In der Zeichnung ist Fig. 1 eine Vorderansicht und Fig. 2 ein Schnitt.

  Starting crank with protection against recoil.



   The invention relates to a crank handle for explosive power, transport and lifting machines and aims to render any recoil that may occur during cranking harmless to the operator of the crank. In the drawings, Fig. 1 is a front view and Fig. 2 is a section.



   The driver b guided in a slot of the crank arm a engages both in the approach arranged on the cylindrical or conical shaft c to be rotated or in a groove d and at the same time also in the notch / located on the ratchet hub e. The ratchet wheel s is made of one piece with the hub e and on the hub of the
 EMI1.1
 designed on the one hand radially, on the other hand, cam-like rising. The locking pawl g, which is movable on a fixed part and is pressed against the toothed ring by a spring or counterweight, engages in the ring gear of the ratchet wheel s.

   The load on the crank arms
 EMI1.2
 
How it works: After the crank has been attached to the shaft to be turned, the driver b has been set in the notch of the ratchet hub e and at the same time in the shaft extension d and the ring gear has also been pushed into the fixed pawl y, turning can take place. If a recoil occurs during this, the pawl g holds the ratchet wheel s firmly and the driver b is removed from the one near the ratchet wheel,
 EMI1.3
 released by the crank) at d, so that it can move in the opposite direction without any danger to the person turning.



   In explosive engines, as the speed of rotation of the shaft c increases, the starting crank a is automatically pushed off by the groove (1-a which runs in a curve towards the end of the axis).
