(under subclass 102) Device provided with means connecting a plurality of interposers to each selector element to be moved to effective position by the movement of a selector element.
(1) Note. Mechanism of this subclass type differs from that found in subclass 97 above, in that it includes some form of power drive trains between the coded element and a number of a single interposers (i.e., each interposer controls a single tool pair), while the coded interposer of subclass 97 consists of a unitary element which is engageable with a pluralty of tools to control a plurality of tool pairs.
(2) Note. Fig. 20 represents typical basic mechanism of this subclass. The differently positioned lugs on the levers of keys A and B, constitute, with their levers, coded-selector-means which are adapted to drive distinct groups of interposers.
