Abstract: 618,442. Typewriters &c. EGRY, Ltd. May 8, 1946, No. 13909. Convention date, May 14, 1945. [Class 100(iv)] A manifolding attachment for use in typing a number of superposed fanfolded or interfolded continuous paper webs comprises carbon-holding and web-aligning devices mounted on endless chains carried by a frame adjustable in length, means being provided for maintaining the chains taut in any adjusted position of the frame. The attachment includes a base 10 attachable to or upon which the typing machine M rests, carrying adjustable uprights 12, 18, on the latter of which guide rails 19 are mounted for the rollers 25 of a carriage 22. Pivoted to the carriage at 27 and bearing against stops 24a are brackets 26 carrying a framing comprising angle-bars 29 and tubular members 33 connected by brackets 30, 51. Mounted on pivots 64 on the brackets 51 are forked arms 67 which are engaged with the shaft ends of the platen P so that the carriage 22 partakes of the letter-spacing movements of the platen. Rods 35 adjustable in the tubes 33 to vary the length of the frame carry a cylinder 44 with sprockets at its ends and the shaft 37 of which is connected to a helical spring 63. Other sprockets 52, 57 and 49 are carried respectively by brackets 51, 54 and 46, and endless chains 60 pass around the sprockets. The position of the bracket 46 is adjustable to tension the chains if the frame length is varied. The carbon carrier consists of a plate 70, Fig. 10, with spring fingers 72, lightly engaging the tubular members 33, and posts 76 on which the carbon-carrier strips 77 are held by a keeper-plate 78. The chains 60 pass through brackets 71 on the plate 70 and pins 74 mounted on spring strips 73 attached to the plate releasably engage links of the chains. To cause the webs F and chains to move together when required and to align the webs, the device shown in Fig. 12 is provided. It comprises a plate 79 secured to the chains and having spring-ends slidably engaging the anglebars 29. Pivoted thereto at 85 is a member 89 carrying a pillar 96 with a roller 97 urged by a spring 95 into engagement with holes H in the forms which are at spaced intervals. A tail piece 99a on the member 89 can be engaged with a stud 100 near the lower end of the rails 29 to hold the parts 96, 97 in inoperative position. In operation, with the pillar 96 engaging the forms, the chains 60 are moved as a form is typed and the spring 63 wound up. When the typing of the form on the webs is completed, the platen rotation is reversed until the carbons are free, when the spring retracts the chains with the webs F and carbons C. The pillar 98 is then released from the forms and the plate 79 further retracted until the tail 99 is engaged with the stud 100. During this operation, the carbons C are moved into proper position for typing the next form. The platen is now rotated to advance the webs only, into predetermined position indicated by a gauge mark in which position the pillar 98 can be re-engaged with other holes in the forms. The carbons and webs can then be advanced ready for the typing of the next form, and the preceding typed form can be detached. The devices can be moved out of the way about the pivot 27 when the typewriter is to be used in the normal way. Specification 432,804 is referred to.
