Abstract

119,998. Goss Printing Press Co., (Goss Printing Press Co.). April 23, 1918. Inking-apparatus.-The inking cylinder or drum is driven through a ratchet by gearing from the press, and may be driven independently in the same direction from the ink-supply roller by sprocket gear through a free-wheel clutch. The forme-inking rollers are mounted in pivoted arms and may be moved simultaneously into and out of contact with the forme-cylinder and the inking- cylinder by rods connecting the arms to eccen. trics on a shaft. The forme-inking rollers 15, 17 contact with the forme cylinder 12 and with the inking cylinder or drum 11, and they are carried by pairs of arms 14, 16 respectively pivoted at 14<1> and 16<1>. The arms 16 carry also vibrators 18. Each arm is connected by a rod 19, 22 to an eccentric fixed on a shaft 21. The cylinder 11 is driven normally from the cylinder 12 by gearing 25, 24, 26, through a ratchet-wheel 29 and pawl 28, and when the press is stopped, it may be driven in the same direction by a chain 43 engaging a sprocket wheel 42 fixed on the shaft 27 and a sprocket wheel 44 loose on the shaft 33 of the ink-supply roller 32. The shaft 33 drives the wheel 44 through a free-wheel clutch 46, and is itself driven by worm gear 40 from a shaft 41. This shaft 41 is driven normally through sun and planet gear 49, 50, 51, 52, 54, &c., partly from the press and partly from an independent motor 55, and when the press is at rest by the motor 55 alone.
