Abstract: 231,979. Addressograph, Ltd., and Watts, R. G. Feb. 7, 1924. Addressing-machines.-In addressing-machines for printing on envelopes or of the kind wherein address-plates are fed to printing position below a vertically reciprocated platen actuated from a rotary main shaft, this shaft is rotated by means of a handle and is coupled to the impression and plate feeding mechanism through clutches, either of which can be disconnected by movements of the handle while the shaft is rotated. This provides respectively means for suspending the motion of the platen so as to skip address-plates from which no impression is required, and for interrupting the feed of plates to provide multiple impressions from a single plate. In the former case the envelope feed is incidentally discontinued. The machine mav also print on a web of paper. A main shaft C mounted in bearings b<1>, b<2> carries a flywheel D rotated by a handle d<1>. A platen J, of known construction, is reciprocated by means of a crank, cam, or eccentric M on the shaft C, a connecting rod N, and toggle links F, G.
