Weber, Chicago, Ill. Application February 27, 1933, ‘Serial No. 658,79 Renewed October 27, 1937 15 Claims. This invention relates in general to apparatus for making multiple duplicate copies of type-, written matter in typewriters, or the like, but more particularly it has reference to improve -> merits in an apparatus which provides multiple duplicate copies of typewritten matter substan tially as clear, and of the same quality, as that of the typewriting as appears on the ?rst or original copy produced by the type from the 10 usual typewriter ‘ribbon ‘on, substantially, any @make typewriter. An important object "of the invention contem plates the provision of a parallel series of‘ mov able inked typewriter ribbons interposed in par allel relation with and between the usual ribbon and platen of ‘a typewriter to eliminate the use of sheets of carbon paper and, fonmaking a number of duplicate copies substantially similar to the ?rst copy as produced by the type from the ?rst or usual typewriter ribbon. A further and important object of the inven» tion contemplates the provision of hinged ribbon guide arms which are adapted to receive and guide the ribbon directly from and to the ribbon ' spools in a straight line. A further important object of the invention contemplates the provision of an arrangement of a series of movable typewriter ribbons arranged to travel in unison longitudinally with the typewriter platen carriage and in the manner of the platen during the period of operating the type writer, or instantly after each type-bar stroke. Another important object of the invention con templates the provision of an arrangement‘ of a series of automatically movable type-writer ribbons arranged to travel in a vertical plane and in parallel relation to the longitudinal faceof the type-writer platen, and in unison therewith and in a like manner thereof during the period of operating the typewriter, or instantly after each type-bar stroke. ' ‘ - ' Another important object of the invention con templates the provision of an arrangement of a series of interposed movable type-writer ribbons arranged to travel in a vertical plane in oppo site parallel relation to each other and through~ out the longitudinal face of the type-writer platen between sheets of paper to be printed dur ing the period of operating the typewriter. Another important object of the invention con templates the provision ofan arrangement of a series of interposed movable type-writer ribbons arranged to travel in a vertical plane in oppou site parallel relation to each other and through out the longitudinal face of the 'typefwriter (Cl. 197-453) platen between sheets of paper to be printed, and be adjustable therebetween to different positions, for various color writing, in an arcuate move ment before the platen. Another important object of the invention con- 5 templates the provision of an arrangement of a series of parallel interposed automatically mov able type-writer ribbons arranged to travel in unison with each other in either direction across the longitudinal face of the type-writer platen 10 to provide a series of parallel ribbons throughout the entire length of the platen. _ It is a further and important object of this in vention to provide a simple, but effective, type writer ribbon takeup spool operating mechanism 15 for operating the ribbon, or a series of ribbons, in either direction across the longitudinal face of the platen, and for automatically maintaining the ribbon or ribbons, in taut parallel relation to the face of the platen throughout its entire length 20 during the period of operating the typewriter. The ribbon operating mechanism contemplates the provision of a series ‘of ratchet driving clutches which may be arranged to operate the ribbon or ribbons, in reverse directions across the 25 longitudinal face of the platen. The operating mechanism also contemplates the provision of means by which the driving clutches may be ar ranged in a neutral or inoperative position. _ It is further contemplated to provide in this 30. invention means for engaging the ribbon operat ing mechanism to prevent thesame from paying off ribbon while backing up the 'work on the platen, and, to prevent the ribbon, or ribbons, from being drawn with and between the work 35 while the same is being reversed on the backing up of the platen.‘ ' -' A further and important object of this in vention is to provide parallel inclined hinged ribbon guide arms so arranged and constructed 40 as to carry the ribbon in as direct a path as pose sible to or from the ribbon takeup spools to its above'stated position before the platen. The construction in said arms being such as to per-_ mit the arms to clear the hubs and the heads 45 of set screws that may be in the hubs, of the platen on any make typewriter in order that the ribbon, or ribbons, may be guided from the take up spools to the above stated position before the platen in, as before stated, as direct a. path as 50 possible. There being further provided on the arms, at their outward extremities, means to guide the inclined portion of the ribbon around a lateral or outstanding angular corner to a ver tical horizontal position and parallel with the 55 2 aroaavo longitudinal face of the platen as before stated, and without the ribbon becoming in the least distorted or creased, and with the least possible friction. It is a further object of the invention to pro vide a detachable inclined longitudinal movable carriage for carrying the ribbon takeup and operating mechanism and the ribbon guide arms and other 'mechanism above mentioned. The invention further contemplates the pro 10 vision of a detachable inclinable frame for sup porting said movable carriage and the ribbon mechanism in an angular position normally above and back of the platen of a typewriter. 15 It is further provided that the carriage be oper-' ated in unison with and by means of the platen carriage of a typewriter, or such similar types of machines, during the period of operating the typewriter. ‘ The invention further contemplates the mov ing of a series of ribbons arranged as above stated independently of each other to an in 20 operative position. v > The invention further contemplates the mov 25 ing of the inclined ribbon carriage and its in clinable carrying frame to a position whereby the same, together with the typewriter, may be moved in the usual manner to an out-of-the way place within a standard typewriter drop desk. This invention further contemplates the pro vision of a detached frame or mounting for sup porting the above mentioned mechanism in oper ative relation to the typewriter free and inde ‘ pendently of the typewriter. These and other objects of ‘the invention will be better understood from the several illustra~ tions in the accompanying drawings, and more fully described in the following speci?cation, and 40 more particularly pointed out in the appended claims. _ In. the drawings: Figure l is a plan view of the invention em bodying my improvements as arranged in oper 45 ative' relation to a typewriter, and as seen from the plane i--l of Figure 2; Figure 2 is an end view as seen from the plane 2--2 of Figure 1; Figure 3 is a view as- seen from the plane 50 2-3, of Figures 1 and 2; no part of the type writer carriage, or platen being shown; Figure 4 is an end or side view of the inven tion shown hinged back or folded up in an in operative and out-of-the-way position directly back :of a typewriter, and being ‘supported by 65 in a base in which it may be moved backward or forward several inches; the whole being adapted to be removed and put away for future use; Figure 5 is an end or side view of a portion 80 of the ribbon mechanism and its mounting frame as it may be detachably secured to a typewriter frame-for permanent installation, if so desired, and enclosed with the typewriter in a standard 65 typewriter drop desk; the desk not being shown; Figure 6 is apart sectional view of the rib bon operating mechanism as seen from the plane 6-6, of Figure 1; and, - Figure 7 is a plan view of Figure 6, and shows a portion of an auxiliary manually operated 70 ribbon takeup mechanism whereby the ribbon or ‘ribbons. may be drawn exceptionally taut when it becomes necessary to reverse the type - writer platen, or insert sheets of paper upon which to make copies. a 76 Fig. 8 is an enlarged sectional view showing the assembled relationship of the ribbons and paper sheets. ' Similar characters refer to similar parts throughout the several views. To illustrate the invention I have shown on: the drawings mechanism which successfully operates one or more typewriter ribbons R, back and forth across the longitudinal face of a type writer platen P, whereby a plurality of copies of typewritten matter may be made in addition 10 to and at the’ same time the original copy is being made from the ribbon already installed in a typewriter T, a portion of which is shown in the several views, Figures 1, 2, 3, 4, and 5.
