Abstract

121,140. Jaggers, H. P. Dec. 24, 1917. Joints for link-work.-The rod A for operating the feeding-devices of a power press is connected to the actuating bellcrank lever K by a device for preventing breakage in case the feeding-devices become inoperative, comprising pawls C engaging a notched portion E of the rod A and pivoted on a casing B slidable on the rod A and having a tubular extension on which a block H coupled to the lever K may slide. Normally, springs G keep the pawls in engagement with the recess E, and also at their outer ends the pawls engage inclines on the block H. If the resistance to movement is too great, the inclines on the block H force the pawls apart, so that the whole device can slide to and fro on the rod A. In a modification, the pawls are pivoted centrally, engaging at one end with the rod A and at the other with inclines on the block H.
