Abstract

350,655. Aligning bearings. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Brueshaber, M. W. ; 1122, Jackson Avenue, River Forest, Illinois, U.S.A.) April 16, 1930, No. 12107. Convention date, Sept. 28, 1929. [Class 12 (i).] The antifriction bearings of printing and impression cylinders are so constructed that they are held rotatably in position without tolerance or play relatively to the other member of a printing-couple, so that the positions of the cylinders are not affected when the impression surface and forme pass into and out of operative engagement at the margins of the pages. As applied to a rotary printing-couple in which gravity assists the printing pressure between a forme cylinder 11 and an impression cylinder 12, the shafts 13, 14 of these cylinders are mounted in split bearings comprising two sets of rollers 18, 15, between which are mounted bearer rings 19, 16 on which act other antifriction bearer members in the form of rings or rollers 30 mounted on roller bearings 31. The shaft 13 is mounted in eccentrics 17 held in place by a cap 20, and by means of a worm 22 the eccentric can be rotated to adjust the printing pressure. One of the antifriction rollers 30 is mounted in lugs 24 on the eccentric member 17, so that adjustment of the printing pressure does not affect the relative position of the roller 30 to the shaft 13. The rollers 30 are adjustable to and from the shafts 13, 14 by means of a shaft 25 with an eccentric part 28 for moving the rollers to and from the centres of the shafts 13, 14. The shafts 25 are fitted with square sockets to receive an operating-tool, and are held in adjusted position by set screws 26 accessible through slots 32, 33 in the spaced frames 10, in which the cylinders are mounted. The bearers 16 on the shafts 13, 14 may be replaced by bearer members on the ends of the cylinders.
