Abstract: 367,375. Printing-machines. ADREMA MASCHINENBAUGES, 62, Alt Moabit, Berlin. Nov. 18, 1930, No. 34743. Convention date, Nov. 18, 1929. [Classes 100 (i) and 100 (ii).] Addressing- machines; platen machines; tripping arrangements.-In an addressing-machine of the kind comprising a rocking impression arm actuated by means of a hand-lever, togglelever actuating mechanism is provided, and the hand-lever is arranged below the machine table and projects beyond the front end of the table into an accessible position such that equal force may be applied in the upward stroke in which the address-plate feed takes place as in the downward or impression stroke. As shown, an impression arm 2, Figs. 1 and 5, is rocked about a pivot 13 by means of a hand-lever 3 positioned as shown and arranged to the right of the printing station. The lever 3 is pivoted at 13 also, and has a disengageable connection with an arm 15<1> of a bell crank 15, which is pivoted at 13 and is connected to an extension 14 of the arm 2 through the intermediary of a rod 16, a double arm 17, and a link 19, one of the arms 17 forming, together with the link 19, toggle-levers. The disengageable connection comprises a spring-pressed plunger 21 mounted in the lever 3 and adapted to be withdrawn from an aperture in the arm 15<1> by means of a trigger 26 connected to the plunger by a Bowden cable 25. The address plates are fed along a guideway 9 by means of a reciprocating pusher actuated by a bell crank 28 connected by a rod 33 to the lever 3, and, when a plate to be skipped arrives in printing position, the trigger 26 is pressed so that the arm 2 is not actuated. Printing is effected through an ink-ribbon 7. Full-stroke mechanism.-This prevents return movement of the lever 3 before a stroke in either direction has been completed. In one form, a spring-controlled pawl 56, Fig. 5, mounted on the lever rides over a stationary rack 55 and drops over the end of the rack at the end of each stroke into a trailing position ready for the next stroke. In another construction, a disc 58, Fig. 13, pivoted to the lever 3 carries two eccentrically-mounted rollers 59 provided! with projecting pins 59<1> connected by a spring 60. The rollers 59 embrace a bar 61 loosely pivoted at 62 and provided with recesses 63<1>, 67 arranged respectively above and below cams 63, 66 fixed to the bar. At the end of each stroke, the recesses allow the rollers to turn into a neutral position with the pins 59<1> in line with the roller axes, and, on the downward stroke, the cam 63, by engaging the pins, turns the rollers into the position shown, such that an attempt to raise the lever causes the rollers to wedge on the bar 61. On the upward stroke, the rollers are turned into a corresponding position at the other side. One of the rollers 59 may be replaced by a fixed member. Delivery apparatus.-After printing, the address plates drop through an aperture 11, Fig. 1, in the guideway 9 and are directed by a guide 12 into a box 40 removably mounted in a frame 42 adapted to be swung about a pivot 43 from the operative position shown into the brokenline position for removal of the plates. The frame is locked in either position by a spring- pressed plunger 47 mounted in a lug 46 on the frame and engaging a grooved guide 52 provided at each end with a recess to receive the plunger, which is 'withdrawn by axial movement of a handle fixed thereto. The plates are packed in the box 40 and against a holder 45 resiliently mounted on a rod 44 by an oscillating packer 38 actuated from the hand-lever 3. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the frame 42 swings about a pivot at the lowest corner, and a spring-pressed plunger carried by a handle engages notches in a guide to retain the frame in adjusted position. This subject-matter does not appear in the Specification as accepted.
