Abstract: 610,707. Addressing and like machines. ADREMA, Ltd., SANDERSON, T. E. F., and MOON, W. R. H. Sept. 25, 1944, No. 18257. [Class 100 (ii)] In addressing or listing machines of the type wherein printing-plates are fed from a magazine 13 to printing position beneath a platen 12 carried by an oscillating arm 11, a sheet 15 to be printed is cut inwardly at intervals from its edge at the side approaching the obstruction caused to the full width sheet by the magazine 13 and arm 11, prior to its passage through the printing station, and is guided and folded over at the cut side so that its width is reduced whilst passing through the printing station and past the obstruction. The machine is particularly adapted for printing addresses, etc., on list sheets comprising a number of account portions 15a, 15b, &c. the sheets being of a suitable width for an adding machine but too wide for the addressing machine. After addressing, the sheet may be cut from the opposite edge so that the two cuts overlap and sever the sheet. The address-plate feed may be interrupted for repeat-printing, the actuation of the arm 11 for skipping, and both for feeding the sheet into the machine. The sheet 15 in pack form is placed in a holder 19 detachably hooked over a rod 20, passes over a guide plate 18, under a tensioning bar 22 and over a table 10 provided with an adjustable marginal guide 23 and fingers 23a for pressing the sheet towards a toothed feed belt 24. A guillotine 25 rocked about a pivot 26 cuts the sheet slightly more than half-way across, a blade 29 made of metal or plastic material and shaped like a ploughshare bends the sheet over as shown in Fig. 1, the curl being supported by an inner concentric plate carried by a rail 35 which unfolds the sheet so that it lies flat on the table again. A guillotine 38 makes a cut in line with the first cut so as to sever the sheet, the end of the blade 38 being of T-form, Fig. 9 (not shown), to make a cross cut ensuring complete severance. The end 34 of the blade 29 is shaped so as to expose a number on the under side of the sheet for comparison with the address-plate. The belt 24 is driven by gearing from a ratchet wheel turned by a pawl linked to an arm 43 normally coupled to the oscillating impression arm 11, and the guillotines are actuated by a cam 'rotated by a pawl also linked to the arm 43, the cam having three recesses into each of which in turn a pin on the end of an arm connected to the guillotine 38 is forced by pins opposite the recesses. The machine is started by pressing a clutch pedal A, and skipping is effected by pressing a pedal B connected by a cable 72 to a pin 74 normally coupling an arm 41 to the impression arm 11 which rocks about a pivot 42. For feeding a sheet into the machine, either of two pedals C, C' joined together is pressed, whereby a cable 79 lowers a latch 81 normally connecting the arm 41 to the address-plate shuttle, a cable 78 pulls down a slide 44 normally coupling the arms 41, 43 together to connect the arm 43 to a rod 83 on the arm 41, and and the pedals A and B are depressed, so that a cycle of operation is initiated but only the sheet-feed and the guillotines are actuated. To prevent damage by moving the slide 44 except when the arm 11 is in the raised position, the engaging parts of the slide are chamfered, or a sliding catch, Fig. 8 (not shown), is mounted inside the slide 44 so as to engage a slot in the arm 43 and prevent movement of the slide except when the arm 11 is in the raised position, the catch being then withdrawn. Specification 548,563 is referred to.
