907,168. Printing-machines. GOTTSCHO Inc., ADOLPH. Oct. 10, 1960 [Nov. 6, 1959], No. 34601/60. Class 100 (2). A marking apparatus comprises a rotatable marking wheel carrying marking means at its periphery for applying inked markings to an article moving therepast, an inking roller rotatable on a shaft extending axially therethrough and supporting the inking roller in rolling contact with the periphery of the marking wheel for applying ink to the marking means, bearing means supporting each of the opposite ends of the shaft, and in each of said bearing means a resilient disc which has the related end portion of the shaft extending therethrough and which is yieldable to permit displacement of the axis of rotation of the inking roller with respect to the axis of rotation of the marking wheel for ensuring uniform contact of said inking roller with the marking means. The marking drum 48, Figs. 1 and 2, is secured to a vertical shaft 46 rotatable in an arm 36 pivoted on a rod 28 arranged beside an article conveyer 14, and the two limbs of a U-shaped spring 64 resiliently hold the arm against swinging in either direction. Articles A to be marked pass along the conveyer in succession and each rotates the drum 48. A helical spring 86 extending round a fixed bolt 88 and a grooved roller 84 on the shaft 46 is stretched when the drum rotates, by means of a grooved roller 82 carried on a member 78 secured to the shaft 46. The member 78 is formed with a stop 100, engagment of which with a latch 94 limits clockwise rotation of the drum. As each article passes out of contact with the drum, the spring 86 returns the drum to its zero position defined by the latch. Inking-apparatus.-The ink fountain consists of a hollow vertical reservoir roller 110, a felt wick 118 extending upwardly from within the reservoir over the top of the side wall 116 and down over the outside of the roller, being surrounded by an annular feet pad which is in contact with and rotated by the raised type 58 on the drum 48. A nut 124 adjusts the ink supply by pinching the wick between the side wall and a cover 122. The roller shaft 126 is supported in resilient rubber discs 144 held in circular recesses in arms 132, 134 pivoted on a spindle 138 supported on the arm 36. The roller 110 is located by means of a clamping nut 142.
