Abstract
547,855. Coating surfaces. COPELAND, R. J., and BLOORE, E. J. March 12, 1941, No. 3385. Convention date, March 23, 1940. [Class 95] [Also in Group XVI] Cylinder tripping arrangements. In a rotary mirror - script duplicating machine, the impression roller 27 is tripped for a part of each revolution of the printing cylinder 9 by a removable or adjustable cam 30 rotating with the cylinder. The cam may consist of an arcuate bar removably secured to the cylinder by dowel pins and spring clamps, or, as shown in Fig. 9, may comprise two quadrantal plates 34 pivoted together and controlled by springs 37 and pivoted eccentrics 36 so as to project into an operative position or be retracted into an inoperative position as shown in dotted lines. Damping apparatus. A tray 38 is provided with a shallow central well 43 supplied with liquid from a container 50 on the bird fountain principle. A wick 46 partly immersed in the well 43 has parts resting upon a pad 48 resting on an inner tray 44 and having a part exposed between the edge of the tray 44 and the edge of a covering shield 45. The pad is preferably enclosed in a chamois leather cover Sheets passing from a feed table 60 having an indicator 61 and guide 62, are pressed against the exposed face of the pad by a plate 55 carried by a bar 56 having an arm 57 actuated at one point in each revolution of the pointing cylinder by a pin 58 to move the plate 55 away from the pad to allow of the insertion of the sheet.
