 der Schiefstellung des Spreizehebels, wenn auch nur in geringem Grade herbeiführt, wodurch eine leichte Verminderung der Bremswirkung, wenn auch nicht die völlige Aufhebung derselben, eintritt. Es ist daher beim Senken nicht die volle Bremswirkung, die bei der ruhenden Last vorhanden ist, zu überwinden. 



   PATENT-ANSPRÜCHE :   1.   Bremse für Hebezeuge nach dem Patente Nr. 43284, dadurch gekennzeichnet, dass statt zweier Bremsbacken nur eine einzige in Form eines aufgeschnittenen, in sich zusammen federnden 'Ringes   (s)   innerhalb eines feststehenden Bremskranzes (e) vorhanden ist und der in die Aufschnittstelle dieses Ringes eingefügte Spreizhebel (i) an der Lastwelle drehbar gelagert ist, wogegen mit dem   Antriebroa8chinenteil   ein Mitnehmerkörper (u) verbunden ist, der je nach seiner Drehungsrichtung mit einer Anlagefläche (v, w) entweder auf den Hebel oder unmittelbar auf den Bremsbackenring wirkt, wodurch im ersteren Falle Aufhebung der Bremswirkung, im letzteren Falle Überwindung der Bremsreibung erreicht wird.

 the misalignment of the spreader lever, if only to a slight extent, whereby a slight reduction in the braking effect occurs, even if it does not completely cancel it. Therefore, when lowering, the full braking effect that is available with the static load cannot be overcome.



   PATENT CLAIMS: 1. Brake for hoists according to patent no. 43284, characterized in that instead of two brake shoes there is only a single one in the form of a cut-open, resilient ring (s) within a stationary brake rim (s) and the expansion lever (i) inserted in the cut-off point of this ring is rotatably mounted on the load shaft, whereas a driver body (u) is connected to the drive mechanism part, which depending on its direction of rotation with a contact surface (v, w) either on the lever or directly the brake shoe ring acts, whereby in the former case the braking effect is canceled, in the latter case the braking friction is overcome.

Claims (1)

2. Bremse für Hebezeuge nach Anspruch 1, dadurch gekennzeichnet, dass die Anlagefläche zwischen dem MitnehmeTkörper (v) des Antriebmaschinenteils und dem Spreizhebel (i) sich bis über die Drehachse (d) des Hebels hinweg erstreckt und so gerichtet ist, dass sich der Hebel bei seiner Anlage gegen den Mitnehmer radial einstellt und keine Spreizwirkung ausübt und der Druck des Mitnehmers ohne Drehung des Hebels auf dessen Drehzapfen (d) an der Lastwelle übertragen wird. 2. Brake for hoists according to claim 1, characterized in that the contact surface between the driver body (v) of the drive machine part and the expansion lever (i) extends beyond the axis of rotation (d) of the lever and is directed so that the lever extends adjusts radially when it rests against the driver and does not exert any expansion effect and the pressure of the driver is transmitted to the pivot pin (d) on the load shaft without turning the lever.
