Abstract

266,916. Victory - Kidder Printing Machine Co., Ltd., and Wilson, H. W. V. March 17, 1926. Inking-apparatus. - Inking-mechanism for printing-machines consists of a hollow feed pipe or channel carrying a number of duct-members arranged side by side and each in communication with the interior of the feed pipe, the ductmembers being provided with nozzles located in proximity to a distributing-cylinder and being adjustable relatively thereto. The ink feed-pipe consists of a rotatable hollow shaft 12 one end of which is closed and the other open and adapted to be rotatably connected to the ink supply, the ink being fed by gravity or a pressure device. The shaft 12 is slotted at intervals, and the slots 14 communicate with channels 16 formed in duct-members 15, a number of which are arranged side by side on the shaft 12. The number of duct-members may correspond to the number of columns in the sheet to be printed. The channels 16 are connected to nozzles 17 formed between the ends of the duct-members and plates 18 secured thereto. The ink passes from the nozzles in a series of ribbons to a cylinder 20 whence it passes to the distributing-cylinder 33 which runs at the same speed as the printing- cylinder but faster than the cylinder 20. The cylinder 20, which may be dispensed with, is preferably adapted to have its speed controlled, and is also adjustably mounted. To vary the amount of ink fed to the cylinder, the ductmembers 15 are simultaneously or independently adjustable. Secured to the shaft 12 is a wormwheel sector 22 engaged by a worm 23 on a hand-operated shaft 24 mounted in the framework of the machine, so that rotation of the shaft 24 results in the adjustment of all the duct-members towards or from the cylinder. An arm is secured to the end of the shaft 12 opposite to the worm-wheel sector to which it is connected by a bar 28. Screws 30 engage with the bar 28 or with non-rotatable bushes 29 secured thereto, and with bushes 32 secured in arms 31 on the ductmembers 15, so that movement of any screw 30 results in the movement of the corresponding duct-member.
