Abstract: 738,499. Autographic registers. LAMSON PARAGON SUPPLY CO., Ltd. Nov. 16, 1953 [Aug. 15, 1952], No. 20613/52. Class 16. [Also in Group XVI] An autographic register wherein continuous webs of stationery are adapted to be fed each time the register is actuated and having means for imprinting on the webs within the register, comprises a printing plate carrier mounted for movement in a horizontal plane between a printing plate receiving position outside the register casing and a printing position within the casing beneath the portion of the webs to be imprinted and a platen member mounted above the webs for movement relatively to the printing plate carrier when the latter is in printing position to effect an imprint on the webs of data on a printing plate positioned on the carrier. The register comprises a casing 1 and the usual form advancing means including a shaft 2 operated by a crank handle 3. The printing plate carrier 4 is pivoted to the casing 1 on a pivot pin 5 and has a recess 6 for the embossed printing plate. A lug 7 is provided for manually rotating the carrier 4 into printing position, shown in dot-dash lines, and a spring surrounds the pivot 5 to return the carrier to the outer position. The carrier 4 is retained in its inner position by a pivoted lever 9 having a projection 10 to engage the carrier edge, the carrier being released on operation of the register by a cam 2a on the shaft 2 lifting a nose 9a on the lever 9. To ensure that the register cannot be operated unless the carrier 4 is in printing position, locking means may be provided comprising a latch 21 engaging a lug 25 on the crank handle 3, the latch being pivotally mounted on a shaft 22 connected by a link 23 to a bell crank lever 24, the lever 24 being pivoted to release the latch 21 by the carrier 4. In one embodiment, not shown, a stud on the carrier 4 strikes the free end of the bell crank lever 24 or, as shown in Fig. 4, a recess 4a is provided in the carrier 4 extending into the recess 6 so that if no plate is in the carrier the lever 24 is not moved but if the printing plate is in position, the lever 24 is operated thereby to release the latch 21. As shown in Fig. 2, the platen member comprises a roller 11 mounted on an arm 12 pivoted at 13 to a carriage 14, the carriage 14 having rollers 15 operating in tracks 16 extending transversely of the register. A plate 17 is attached to the arm 12 and urged by a spring 18 on the carriage 14 to pivot the arm 12 so that the roller 11 is raised out of printing relation with the plate on the carrier 4. Prints are made by the roller 11 being impregnated with ink, for example, and by carbon between the webs and printing is effected by movement of the arm 12 first to the dot-dash position shown and then across the register, the carriage 14 being returned by a cord 19 secured to a drum 20 rotated by a spring, the spring 18 causing the rotation of the arm 12 so that the roller 11 is again held out of printing relation. As shown in Fig. 6, the printing roller 32 is mounted between a pair of parallel arms 30 pivoted on a rod 31 in a printing head 27 pivoted at 28 to the register casing 1, a spring loaded stop 29 being provided to hold the head 27 with the roller 32 spaced just above the superposed webs and the printing plate 6a. The arms 30 are connected to an extension 34 of a hand operated lever 35 by a link 33 and a relatively strong spring 33a connects either the arms 30 or link 33 to the head 27. Downward movement of the lever 35 depresses the leaf spring 29 to bring inkimpregnated roller 32 into contact with the webs and further downward movement actuates the link 33 to oscillate the arms 30 and roller 32 to effect an imprint. The leaf spring 29 raises the roller 32 with the head 27 and spring 33a returns the arms 30 and roller 32 on release of lever 35. In the embodiment shown in Fig. 7, the imprinting of the webs is effected on actuation of the crank handle 3. The pivoting roller 37 is mounted on an arm 38 pivoted at 39 to a sliding carriage 40 and connected by a cable 41 by means of pulleys 42 (not shown), 43 to an arm 44 freely rotatable on the operating shaft 45 of the register, the crank handle 3 also being freely rotatable on the shaft. The arm 38 is connected to a spring 52, which passes over a pulley and is connected to the casing, by which the carriage 40 is returned. The crank handle 3 carries a pivoted latch device 46 urged by a spring 47 into engagement with an abutment 48 on the arm 44, the latch 46 being released by engagement with a cam plate 51 as the crank handle 3 is turned through about 45 degrees. This initial movement of the handle 3 therefore operates the carriage 40, the cable 41 first pivoting the ink-impregnated roller 37 downwardly into contact with the webs and printing plate and as the latch 46 is released, the spring 52 lifts the roller 37 and returns the carriage 40. Further movement of the handle 3 then engages a lug 50 on a lever 49 fast to the shaft 45 to rotate the shaft and actuate the web feeding means of the register. When a printing plate is to be used for more than one operation of the register, means may be provided for retaining the carrier in the inward positon.
