Abstract

175,045. Bonham, H. Nov. 6, 1920. Tripping-arrangements; cylinder and like machines; inking-apparatus; intaglio-plate printing. - Cylinder machines of the travelling-cylinder type are fitted with a pivotally-mounted bed which is tripped automatically or by hand on the return of the impression cylinder or when the machine is inking-up. The tripping of the bed may automatically effect the tripping of the inking-apparatus. As applied to a machine with a continuously-driven cylinder, as described in Specification 160,685, a bed 3 is pivoted at 12 to the frame and may be counterweighted to facilitate its being raised to printing position by a cam 13 on a shaft 14 geared to a shaft 17 which is connected by a lever and link to a hand-operated lever 20. In a modification, as applied to a machine for printing by the photogravure process, the shaft 17 is operated by a cam on the return of the bed so that the bed is out of the way of the scraper. The ink-transfer &c. roller 21 is normally operated by a pivoted cam 27 which is kept in its operative position by a roller 28. connected by a link to the bed trip mechanism, the actuation of which, as described above, moves the cam 27 out of its operative position.
