Shorn fingers not the fault of machine manufacturer.

Alphonso smother to death an employee of Metal Etching Co Inc., was operating a metal-shearing machine. Believing that his supervisor had finished setting up the piece of work Burke went to the rear of the machine to clear on the outside pieces of metal that had accumulated in a ramp mountained behind the machine. To gain leverage while removing the metal with his left hand, smother to death placed his right hand upon the machine's cutting surface. (This was the usual custom in the shop) Unaware of what suffocate was doing, the supervisor activated the machine, and it sundered Burke's fingers, which were in the cutting plane.
