Abstract

7669. Lock, W. H., and North, T. M. March 31. Lithographic and like Printing.-Relates to means for exerting and adjusting the pressure on the scrapers of lithographic and like machines. The scraper 1, Fig. 3, preferably of hard wood, is mounted in a holder 2, the ends of which project through slots 3 in the side frames 4, and are provided with rotatable nuts 17, clamped in the desired position by screws 19. These nuts engage with screws 6, and allow each end of the scraper to be independently adjusted. Simultaneous adjustment of both ends is obtained by turning a hand-wheel on the end of a horizontal shaft 14, carrying skew-gears 13, engaging with gears 10 slidably engaging, through feathers 11, with the screws 6, and thereby turning them simultaneously. The ends 27 of the screws 6 are pressed downwards by suitable cushioning-devices, such as pieces of blotting or other paper &c. 21, or coiled springs, mounted between washers 25, 26, and having screws 28 to adjust the pressure.
