Abstract

604,565. Copying documents. BLOCK & ANDERSON, Ltd., and GERLACH, H. Nov. 27, 1945, No. 32036. [Class 100(ii)] In a rotary hectographic copying machine in which the pressure of the impression roller against the master cylinder is adjustable and an indicator is provided for indicating the pressure, the indicator comprises a member movably mounted immediately behind a fixed window aperture and carrying spaced inscriptions displayed selectively in accordance with the pressure adjustment. Two arms 6 pivoted at 7 and carrying the impression roller 4 are engaged by adjustable bolts 13 carried by arms 11 fixed to a shaft 12. An arm 16 fixed to the mid-point of the shaft 12 carries a cam roller 20 adapted to engage a number of recesses in a cam 19 fixed on a shaft 18. A hand lever 17 is fixed to the shaft 18 at one side of the machine so that the cam 19 can be rotated to vary the pressure between the impression roller 4 and the master drum 1. A segmental indicator 23, bearing spaced inscriptions, is pivoted at 24 and visible through an opening 27 in the front of the frame and to one side of it, is connected to the lever 17 by a link 21 so that the setting of the cam 19 is indicated at the opening 27. Preferably the indicator 23 is arranged above and the lever 17 below the feed table 8.
