Abstract

533,600. Printing surfaces. GOSS PRINTING PRESS CO., Ltd. Oct. 18, 1939, No. 28183. Convention date, March 28. [Class 100 (ii)] A stereotype plate, e.g. a tubular plate 2, is tensioned around its supporting cylinder 1, by a pivoted jaw 35 pressed into engagement with an internal projection 7 on the tail end of the plate, by a number of spring pressed plungers 45 engaging a projecting part 41 of the jaw. This jaw is mounted on pivots 39 to which is secured externally of the cylinder an arm 54 carrying a roller 55 which, when the jaw is in operative position, lies in a cam recess 56 in a ring 57 free upon the cylinder shaft. Upon turning the ring by a bar inserted in a hole 63 in a projecting part 62 thereof, the roller 55 is moved out of the recess 56 thereby turning the jaw 37 into an inoperative position to release the plate. The parts are held in this position by the roller 55 engaging a recess 60 in the ring 57. The leading edge of the plate 1 is held by a jaw 14 engaging an internal projection 15 on the plate, the back of the jaw 14 and the contracting face of a bar 18 being formed with co-operating wedge surfaces which upon moving the bar 18 longitudinally by means of a screw 22 adjust the position of the leading edge of the plate. The jaw is kept in contact with the bar 18 by spring plungers 30. Specification 448,896 is referred to.
