620,148. Inking-mechanism. GOSS PRINTING PRESS CO., Ltd. April 29, 1946, No. 12921. Convention date, May 22, 1945. [Class 100 (ii)] In an inking-mechanism for a printing press in which a fountain roller 11 and a pick-up roller 39 cooperate to transfer ink from the roller 11 to the roller 39, the latter is mounted on bearings 41 for free rotation about a shaft 42 which is supported in eccentric bearing members 44 and a single adjusting mechanism is provided whereby a predetermined angular movement may be imparted to the shaft to vary the spacing between the rollers while maintaining ink transfer relationship. The eccentric 44, Fig. 2, is keyed to the shaft 42 and is rotatably mounted in a bracket 40, the other end of the shaft 42 being similarly mounted. An operating lever 50 is keyed to the shaft 42 and connected through a link 64 to a bell-crank lever 60 which when actuated separates the rollers 39 and 11. A rod 71 is pivotally connected to an oppositely-extending portion 70 of the lever 50 and is loaded by a spring 73 to urge the roller 39 into the ink-feeding position. The spring 73 is interposed between a fixed stop 74 and adjusting nuts 75 and 77. A finger 80 formed integrally with the lever 70 co-operates with a stop-screw 81 to control the upward movement of the finger 80 and to provide a micrometric adjustment for the position of the roller 39. The stop screw 81 is rotated by a threaded sleeve 85 screwed in an internallythreaded bracket 87 by a worm 88 carried on a shaft 89 rotated by a hand-wheel 90. A dial 95 is fixed to the top of the sleeve 85 and cooperates with a pointer 96 to indicate the magnitude and direction of rotation of the hand-wheel 90. Specifications 548,641 and 598,634 are referred to.
