An inking-roller o working over a pad g is carried by levers n pivoted at m on the head f and oscillated by means of forked extensions engaging studs p on the head f. A needle:pointer is carried by levers y, w. In the arrangement shown in Fig. 5, the fillets or leads k forming the stave type are supported on a carrier c actuated by means of a pedal-operated lever d and a returning spring h. The lever d is provided with an adjustable screw stop. The levers n carrying the inking-roller m are pivoted at o on the framing and at p on the carrier c. Two pointers are provided. The machine may be operated by gas, electricity, &c.
