ABSTRACT:
A pad printer device includes a base member (2), a table member mounted on the base member, a slide member (3) slidably mounted on the table member for movement between at least two positions, and a printing pad (17) supported on printing arm (16) mounted on a support block (15) slidably mounted in a box-like column (9) extending upwardly from base (1). Printing pad (17) is reciprocated vertically by lever-type arm (25) pivotally engaged (27, 28) with support block (15) so that operation of the arm reciprocates the printing pad vertically. An adjustable limit gauge device is mounted on slide block (15) and includes two separately operable set screws (30, 31) which separately engage with rotatable stop member (47) rotatably mounted on base member (1) for positioning thereof for engagement with the lower ends of the set screws. The stop member (47) is rotated by a cam (46) connected thereto through a cam sleeve (45) pivotally mounted on a cam shaft (43 ), the cam (46) having parts (48, 49) extending into the path of movement of a cam operator (40) mounted on sliding block (36) which is part of the slide assembly, so that reciprocation of slide assembly (3) in one direction rotates stop member (47) into position for engagement with the lower end of one of the gauge screws and operation of block (36) in the opposite direction rotates stop member (47) in the opposite direction for engagement with the lower end of the other gauge screw, so that the force applied by printing pad (17) is controlled, or standardized, for each operation thereof in either position of the slide assembly (3).
