ABSTRACT:
A metal forming machine for forming articles from metal workpieces has a plurality of driven members for performing work on the metal workpieces. A drive shaft is connected with the driven members for transferring force to the driven members. A frangible portion is connected in the drive shaft and is designed to fail upon the occurrence of a predetermined overload at the member being driven from the drive shaft. A signalling device is associated with the frangible portion to stop the machine and give an alarm when an overload occurs which breaks the frangible portion.
