DEFINITION

Classification: 234/78

(under subclass 76) Device including individual tool-actuating power trains, said power trains comprising spaced driving and driven elements with lost motion or misalignment therebetween, and means to support said pattern generally between said driving and driven elements so that portions of the pattern serve to complete the driving power trains to the so-selected tools.

(1) Note. The pattern has the form of an inverse stencil (i.e., having blank areas corresponding to holes to be punched, and holes corresponding to areas to be left unpunched).
