Abstract: 348,022. Printing-machines. ADDRESSOGRAPH CO., 901, West Van Buren Street, Chicago, U.S.A. Jan. 31, 1930, No. 3327. Convention date, Nov. 1, 1929. [Classes 100 (i) and 100 (ii).] Addressing and like machines.-A machine for printing and addressing bills, statements, notices &c. of the kind shown in Fig. 10 comprising a main portion A and stub portions A<2> which can be separated therefrom along perforated lines A<3> is constructed with means for feeding a web B from a roll C, Fig. 4, and with a reciprocating cutter 28 for cutting a short length from the web. The severed sheet is received in a guide-way 49, Fig. 6, in which are guides 56, 58, and the sheet is moved by belts 60, 61 and co-operating rollers in a direction inclined, preferably at a right angle, to the direction of motion of the web, and is printed in succession with addresses on the main and stub portions of the sheet by means of an addressing mechanism of known kind comprising an oscillating stamp C, an ink ribbon 79, and address plates 75, which are automatically fed and delivered, and which remain in printing position until the desired number of impressions has been printed. The sheets are held in position to receive the impressions from the address plates by means of stops 84, Fig. 3, which are successively depressed into position to engage the front edge of the sheet by cams on a shaft 87. After the last address is printed, the sheet is advanced by dropping rollers 113, and is led to a rotary printing couple 90 such as is described in Specification 348,025, from which it is delivered by a conveyer 91. Feeding and winding webs ; cutting and perforating apparatus.-The web B is fed from a roll C, Fig. 13, secured to an axle 121 supported on rollers 122 in pivoted yokes 123 fitted with levers 126 by means of which the yokes may be depressed to the position shown in dotted lines for the insertion of a new roll. The axle 14 is mounted so that it can be adjusted axially to enable the web to be adjusted laterally. The web passes over a roll 135 mounted in spring-controlled pivoted arms 136, and over a turning roller to feed rollers 3, 4, Fig. 6, geared together and rotated intermittently by adjustable crank-mechanism which oscillates a segmental gear which drives the roller 4 by means of a roller clutch. Reverse motion of roller 4 is prevented by a similar clutch. The web is gripped for a portion of its width only by means of a part of the roller 3 which has a slightly enlarged diameter, and the roller 3 is formed with perforating pins to form the lines A<3>. The roller 3 is journalled in arms 5 eccentrically mounted in the machine frame, and by rotating the arms against the action of springs the roller 3 may be raised from the roller 4 to permit threading of the web. The arms 5 are connected by a cross-rod, and pressure of the roller 3 is adjusted by means of screws 8. The knife 28 is shaped like an inverted V, and coacts with a fixed knife 26 to cut the web from the outer edges towards the centre. The knife 28 is yieldingly mounted in a reciprocating carrier 29 operated by a link 30, bell-crank 31, and cam 33. The cut sheet is directed against the side guide 56 by means of rollers 40, 42, the roller 40 being mounted in arms 47 normally raised by springs against stops 52. The arms 47 are depressed by screws 54 in the knife frame 29. Driving-arrangements.-The stamp C and associated parts are driven from a main shaft 65, Fig. 4, driven from a motor by belt gearing, and the shaft 65 is geared to a countershaft, Fig. 11, which actuates the cutting-mechanism &c., by means of a mechanism shown in Fig. 11 adapted to permit of independent hand operation of the shaft 103. In the normal running, motion is transferred to the shaft 103 by a pivoted dog 107 on a gear 1021 geared to the shaft 65, which engages an arm 108 on the shaft 103. When band operation is taking place, the shaft 103 is driven by gearing from a handcrank on a shaft 46, Fig. 4, and the arm 108 rides past the dog 107 in each clockwise revolution of the shaft 103.
