A latch or plunger 66 vis movable axially in said arm under urge or" a spring 68. When the printing roll is elevated above the stencil, the plunger is disposed by said spring away from the path 'of movement of said. pin 64 so that the printing roll is free to rotate. The position of the plunger is controlled by a bracket 'i0 which is fixed to one of the rails of the stencil track 12 and upstands between the plunger-carrying arm 30 and an end of theprinting roll. When the printing roll is in elevated and inactive position the inner end of the plunger 66 is disposed above the top of the bracket. When, however, the arins 30 are lowered toward a stencil the plunger engages a cam face 72 at the upper end of the bracket-.and is moved outwardly there'- by to dispose its outer end in the path or movement of the pin di carried bythe printing roll shaft, thereby to hold said shaft iromrotation.

The plunger is held by the cam face of the bracket against retrac'tile movement While thev printing roll is in engagement with the stencil. The relation between the pin, plunger and groove of the printing roll is such that the roll is held against rotation with its groove 5,6` above the Aunwanted characters of the-stencil when the printingV roll is in active position.

It is apparent that the groove or relieved portion 56 will have different dimensions, in different rolls, depending upon the area occupied by the unwanted characters of the stencil. v

The transfer roll 4Q-is arranged tomake but light pressure engagement withthe periphery of the .printing roll, the engaging pressure being controlled by the adjustable 'screw 74 which is threaded ina supporting arm of thevtransfer roll and bears againstthe frame 32 of the printing roll.
