Abstract: 228,183. Elliott, H. P. Jan. 24, 1924, [Convention date]. Addressing and like machines.-In an addressing or like machine for printing from stencils of the kind having means whereby multiple prints may be made from a selected stencil, the action of the stencil-advancing means is arrested and the selected stencil is moved out of and into printing position by other means when multiple prints are desired. There are also described an arrangement for skipping stencils from which no impression is desired, a dating device, guides for positioning sheets in the machine, and inking-apparatus. A counter is also provided. General arrangement. Stencil cards 12, are stored in a magazine consisting of channelled members 18, 19 secured by screws 20 to slotted bars 14, 15, which together provide a stencil track 16. The cards are detached and advanced along the track by a reciprocating pusher 50 actuated from a hand crank 41 through a connecting-rod 52 formed in two parts adjustably connected together at 53. Printing is effected by inking and impression segments 25, 26, after which the cards are delivered into a hopper 23 adapted to be inverted so as to lie on the track. The segments 25, 26 are mounted on shafts 35, 27 geared together, the shaft 35 having an arm 40 whereby it is driven from the crank 41. Stencil-retrieving device. This is slidably mounted on the guide bar 14 and consists of spaced plates 90, 91, Fig. 11, resiliently connected together so as to provide a frictional grip on each stencil in succession. Normally, the stencils hold the retriever up to a front stop 101 against the action of a spring 97; when, however, the feed of the stencils is interrupted by disabling the connecting-rod 52, the consequent gap allows the retriever to return the stencil to its former position in front of the pusher 50. A pawl mounted in a recess in the bar 14 prevents unintentional backward movement of the stencils. The rod 52 for actuating the pusher 50 is detachably connected to the hand crank 41 by its hooked end 56, Fig. 14, engaging over a crank-pin 43 on the crank arm. A yielding pin 57 holds the rod 52 in engagement such that downward pressure on the rod will release it. Stencil-skipping device. The arm 40, through which the inking and impression segments are driven, is detachably connected by means of a spring plunger 44, Fig. 3, to the crank 41 so that the drive to the segments may be interrupted while the stencils are still being fed. A pawl prevents backward rotation of the. arm 40. Printing-surfaces; holders for loose types.-A dating segment 110, Figs. 3 and 12, provided with a slot 111 to receive types 112, is mounted on the shaft 35, the date being printed simultaneously with the address. The segment is formed on a grooved hub 113 which, together with a complementary part 116, is secured on the shaft 35 by means of a clip 117. A co-operating impression segment 115 is provided. Inking-apparatus.-The segment 25 is inked by a roller 73, Fig. 1, mounted in eccentric bearings 74 adjusted by a handle 75. A pivoted ink reservoir 77, in which is a toothed duct roller 78, supplies ink, when the reservoir is raised by hand, to a messenger roller 80 carried in a pivoted bracket 83 spring-pressed against the inking-roller 73. A pivotal protecting cover 86 is provided. Counting-apparatus.-The arm 131 of a counter 130, Fig. 1, is actuated from the arm 40.
