(3.) In a printing, embossing, or printing-and-embossing press of the kind in which a die-carrying arm is fixed to an intermittently revolved shaft, the combination with said die-carrying arm and shaft of a die, a die-inking apparatus, a die-wiping apparatus, a device adapted to resist the impression-blow, a lay-over device, a cam carried by said shaft and operating the wiping-apparatus, and a cam also carried by said shaft and operating the lay-over device, which is thereby moved above and below the active face of said resisting-device, as set forth. (4.) In a printing, embossing, or printing-and-embossing press of the kind in which a die-carrying arm is fixed to an intermittently revolved shaft, the combination with said die-carrying arm and shaft of a die, a die inking apparatus, a die-wiping apparatus comprising a wiping-pad and a strip of paper adapted to be intermittently fed across said pad, a device adapted to resist the impression-blow, means for causing the die to give the impression-blow, a lay-over device, and cams carried by said shaft and adapted to operate at the required times the wiping-apparatus and the lay-over device, and to feed the paper strip, as set forth. (5.) In a printing, embossing, or printing-and-embossing press of the kind in which a die-carrying arm is intermittently revolved from a continuously driven shaft, the combination of gear for causing the revolution of said arm, means for locking said arm in the printing position, and means for gradually setting said die-arm into motion, independently of said gear, as set forth. (6.) In a printing, embossing, or printing-and-embossing press of the kind in which a die-carrying arm is intermittently revolved from a continuously driven shaft, the combination with die-arm-locking means of a rotary cam, a lever actuated by said cam, a locking-block engaged by said lever, and a projection on said die-arm capable of being held by said block, a wedge surface on said lever and another wedge surface carried by the die-arm, as set forth. (7.) In a printing, embossing, or printing-and-embossing press of the kind in which a die-carrying arm is intermittently revolved from a continuously driven shaft, the combination with the die-arm-locking means of a rotary cam, a lever actuated by said cam, a locking-block engaged by said lever fitting and sliding in a rectangular channel in part of the press-frame, a wear-compensating strip adjusted by a screw, and a projection on said die-arm capable of being held by said block, a wedge surface on said lever and another wedge surface carried by the die-arm, as set forth. (8.) In a printing, embossing, or printing-and-embossing press, the combination with the press-frame of an anvil surface, frames fixed around said anvil surface and formed with projections ground to gauge and adapted to bear against the edge of a counter-plate, a fixed pin adapted to enter a recess on one side of said counter-plate, the under edges of which are recessed to receive removing-tools, as set forth. (9.) In a printing, embossing, or printing-and-embossing press of the kind in which a die-carrying arm is intermittently revolved from a continuously driven shaft, the combination of a die-inking apparatus, a die-wiping apparatus, and means for causing the die to give an impression, comprising a vertical screw plunger carrying a weighted fly-wheel and a pinion, spring-pressed racks engaging said pinion and contained in tubular boxes provided with screw spindles, a continuously rotating driving-part, means for intermittently connecting said plunger thereto, and for locking and releasing the said parts, as set forth.
