DEGENER, F SAN FRANCISCO, CALIFORNIA, ASSIGNOR-T0 ROYAL 'IYPE- WRITER COMPANY, INC., OF NEW YORK, N. Y., AV CORPORATION OF NEW YORK MANIFOLD'IN G DEVICE Application filed October 27, 1930. Serial No. 491.558.

This invention relates to new and useful improvements inI manifolding devices which may be readily attached to any standard typewriting machine without changing such machine in any material respect, and embodies certain improvements over the inventions disclosed in my co-pending applications Serial No. 133, 87. liled Sept. 8, 1926, and in the divisional application thereof 3.0 Serial No. 194,135, led May 25, 1927, and

in application Serial No. 359,934, filed May 2, 1929. The present invention, and likewise the inventions of the co-pending applications above noted, is designed for the purpose of writing on continuous forms of work sheets which are frequently hundred feet.

Among the several objects of this invention are to provide a single operating lever, such in lengths of several 33 as the carriage return lever, for first bodily moving the platen rearwardly and thereby relieve the normal tight contact relation between the platen and the work sheets and interleaved carbon strips, to apply a gradually 95 increased tension to the carbon strips and to simultaneously effect a feeding of said strips during the baelnvard movement of the platen, and to effect a line spacing movement to the paper clamp while the platen is in its relieved position and subsequent to the carbon strip feeding movement but while the maximum tension on the carbon strips is maintained, whereby the work sheets during the feeding movement will not only be relieved :T5 of their normal tight contact relation with they platen but will also be fed without dragging the carbon strips therewith; to mount one or more ribbon spools on a single spindle which extends rearwardly from the main E frame and is rigidly connected thereto, and

to provide separating discs between the spools and to /detaehably mount said discs on the spindle whereby said discs will not only maintain the spools in separated rela- 5 lion but will be retained against rotation with the spools; to provide means for guiding the strips forwardly from the spools along the left hand side of the machine. thence toward the right in front of the platen and in interleaved relation with the work sheets, and

thence rearwardly along the right hand side ments and between the rock shaft and the i strip feeding means whereby upon movement of the rock shaft the platen will be bodily moved either backwardly orforwardly and the carbon strips will be fed during the backward movement only of the platen; to provide a collating frame for the work sheets and to mount a truck on the frame for stepby-step movements therealong for line spacing the work sheets by a swinging movement of the manually operable carriage return lever; to provide manually operable means for disengaging the truck from the line spaeing mechanism so as to permit the truck to gravitate along the collating frame to its initial position; to provide said truck with a manually operable means for first releasing the clamp of the truck from the work sheets and-foi` subsequently releasing the truck from the line spacing mechanism; to provide a novel means for mounting the nonrotatable platen on the collating frame and for mounting the entiretyon -the carriage whereby upon operation of the carriage re-y turn lever the collating frame'will be swung forwardly and the platen will be bodily gradually increased tension i moved rearwardly; to provide the collating frame with a vertically adjustable cross bar above the clamp for forming a movable clamping member for the lead-in ends of certain of the work sheets whereby the latter may be separated from the carbon strips by the operator; to provide a table in rear of the platen and movable with the carriage for supporting the Work sheets as they are fed forwardly 'past the platen and to provide said table with laterally adjustable guides for the work sheets whereby the guides may be adjusted for accommodating work sheets of different widths; to provide such atable with superposed paper guides which are laterally adjustable independently of one another whereb)Y two set-s of work sheets of different widths, one under the other, may be led to the platen; to provide the table with one or more freely rotatable rolls at the receiving end of the table for guiding the work sheets upwardly and thence forward` lv on to th-e table, and to provide a cutout attachment adapted to be interleaved with the work sheets and carbon strips for preventing writing on certain parts of some ofl the work sheets as may be desired.

'["he invention as illustrated in the accompanying drawings is shown as being applied to the well known standard Royal typewrit-v ing machine, but it is to be understood that my invention is adapted to be applied to other types of typewriting machines, or to calculating machines and the like.

The typewritingv machine includes a main frame A, a carriage B, a platen C, a main ribbon D, type bars E which are o )ei-ated in the usual manner, and the usual ta nilar stop rod F.

The main frame A includes side walls 5 and 6 and a rear wall 7. Fixed to the main frame A is a bottom rail 8 for supporting the carriage ll through the medium of a top rail 9 fixed to the carriage.

The carriage includes end plates 10 and 11 respectively, and rigidly connected to thc front portions of the end plates is a rod 13. Journaled on this rod adjacent the inner faces of the end plates are hanger arms 14. 14 which forln a pivotal support for a co.- lating frame (i and the platen the latter being rigidly connected to the former. The collating frame G includes spaced channel shaped sidi` bars 15 and 1G which are rigidly connected at their upper ends by a cross rod 1.7 which is angular in cross section, and at their lower ends by the platen C. The side hars 15 and 16 are arranged so that the channels open rearwardly. The side bar 15 is thus provided with inner and outer longitudinal flanges 18 and 19 respectively and the side bar 16 is provided with inner and outer longitudinal flanges 20 and 21 respectively. Integral with the lower ends of the flanges 18 and 20 of the side bars 15 and 1G respectively are inwardly extending cupshaped heads 22, each head including a circular wall 23 arranged in the plane of the flange 18 or 20 to which it is attached and a circular flange 24, the wall 23 being provided with a circular opening 25 for receiving the rod 13, the openings 25 being of larger diameters than the rod 13 so as to permit bodily movement back and forth relative to said rod. The platen C is preferably formed of tubular metal and the ends of the platen surround the circular flanges 24. The end portions of the platen are longitudinally slotted as at 2G and a clamp 27 surrounds each end portion of the platen and functions to rigidly connect the platen with the heads 22. It will thus be seen that the platen C forms a rigid connection between the lower ends of the side bars 15, 16 of the collating frame, and that the platen is bodily movable with Said frame. In order to retain the platen C and the frame G against longitudinal movements along the rod 13, I have mounted two stop collars 28, 28 on the rod 13 beyond the heads 22. the diameters of the collars being greater than the diameters of the openings 25.

Journaled in the rear ends of the end plates 10 and 11 of the carriage is a rock shaft 29 and fixed to said rock shaft adjacent the ends thereof are rock levers 30 and 31 respectively, the lever 30 including an upwardly extending arln 32 and a downwardly extending arln 33, and the lever 31 including an upwardly extending arm 34 and a downwardly extending arm 35. Substantially horizontal links 36 extend rearwardly' from the platen C toward the rock shaft 29. These links 36 extend under the rock shaft 29 and have their rear end portions curved upwardly and pivotally connected to the arms 32 and 34 of the levers 30 and 31, as at 3T and 38 respectively. The front ends of these links 36 are pivotally connected as at 38a, 38a to depending lugs 39, 39 integral with the lower ends of the side bars 15, 16 of the collating frame. The front ends ot' the links 36 extend beyond' the pivots 38a and terminate in downwardly extending arms 4t), 4() which are pivotally connected at their lower ends as at 41-41 to the lower ends of the hanger arms 14` 14. Pivotally connected to the upper end of the lever arm 30 by a pivot bolt 42 is the rear end of a link 43, the front end of said
