Abstract

338,208. Mann & Co., Ltd., G., Harker, P., and Turnbull, D. H. Aug. 16, 1929. Tripping-arrangements. - A rotary machine is provided with feeler mechanism to prevent the raising of the front lays and also the opening of feed grippers if the sheet is not presented correctly to the front lays 2, which are carried by a shaft 3. The feelers 12 are caused by arms 11 on an oscillating shaft 10, and if a sheet is positioned correctly the feelers move over a notch 30 in the feed-table 1, and the resultant upward movement of a lever 13 on the shaft 10 causes a slotted link 14 to move a spring-controlled pawl 6 on a lever 7, which is oscillated freely on the shaft 3, to engage a notched plate 5 fixed to the shaft 3, and thus to rotate the shaft 3 to raise the front lays 2. The lever 13 by means of a link 22 operates a weighted pawl 21 and permits operation of the feed grippers 19. If a sheet is not fed correctly, and the feelers 12 engage the notch 30, the pawls 6 fails to engage the plate 5 to raise the front lays, and also the pawl 21 is not operated and the grippers 19 remain closed and so cannot feed a sheet. The tripping of the lays 2 and the grippers may be controlled independently of the feelers 12 by operating the shaft 10 from the usual foot trip shaft for tripping the impression cylinder.
