Shift mechanism in syllabic typewriters

A syllabic keyboard controlled device comprising a fixed framework, a motor mounted on said framework, a driving cylinder coupled with and driven by said motor, a plurality of type bars arranged in groups each of which corresponds to a distinct printing point (FIG. 5a, 5b), each of said type bars having characters arranged thereon in three levels or cases namely a lower case, an upper case and a middle case disposed between said lower case and upper case, a first basket supporting a first group of said type bars, a second basket supporting a second group of said type bars, a third basket supporting a third group of said type bars, means slidably mounting said third basket on said fixed framework for movement from an intermediate rest position for printing middle case characters down to a second position for printing upper case characters and up to a third position for printing lower case characters, means for releasably locking said third basket to said fixed framework in rest position, means for slidably supporting said first and second baskets on said thrid basket for movement relative to said third basket from an intermediate rest position for printing middle case characters down to a second position for printing upper case characters and up to a third position for printing lower case characters, and means for shifting said baskets comprising first, second, and third and fourth shift keys, a first driving shaft, means for releasably coupling said driving shaft with said driving cylinder to rotate said driving shaft, lever means carried by said driving shaft and releasably engageable with said baskets to move said baskets downwards, a second driving shaft permanently connected with said first driving shaft so as to turn in the opposite direction thereto, lever means on said second driving shaft and releasably engageable with said third basket to move said third basket upwards, means actuatable by said first shift key for engaging said lever means of said first driving shaft with said first basket and then coupling said first driving shaft with said driving cylinder to move said first basket alone from said rest position down to said second position, means actuatable by said second shift key for engaging said lever means of said first driving shaft with said second basket and then coupling said first driving shaft with said driving cylinder to move said second basket alone from said rest position down to said second position, means actuatable by said third shift key for unlocking said third basket, engaging said lever means of said first driving shaft with said third basket and then coupling said first driving shaft with said driving cylinder to move said third basket together with said first and second baskets from said rest position down to said second position, means actuable by said fourth shift key for unlocking said third basket, engaging said lever means of said second driving shaft with said third basket and then coupling said first driving shaft with said driving cylinder to lift said third basket together with said first and second baskets from said rest position to said third position, and means for returning said baskets to their rest positions when said shift keys are released.
