Abstract
118,756. Daniels, E. G. Dec. 5, 1917. Punching.-In a punching-machine, the punch 20 is carried by a plunger 51 guided by a member 18 in which gags 26 are slidably mounted, so that, during the up-stroke of the head, they are withdrawn by the levers 30, 37, and adjustable stops 43 release the plunger and allow it to fall on to the work. During the down-stroke, they are drawn into engagement with the plunger by a spring connecting the levers 37.
