Application January 7, 1932, Serial N0. 585,210 46 Claims. (Cl. 197—153) My present invention is concerned with the ribbons or other inking or duplicating agency of typewriting machines, adding machines, ad dressing machines, cash registers and other mech 5 anisms of the character in which individual nu merals or letters are successively imprinted each such imprint appearing concurrently on one or more sheets. - It is an object of the invention to provide a 10 duplicating device for a machine of the above type of extremely simple construction, which may be conveniently coordinated with respect to the sheet or sheets to be imprinted, without alteration in the construction or design of known machines of 15 the character‘by the use of which extra copies were heretofore produced by resort to carbon paper. Another object of the invention is to provide a ribbon holder ‘which may belmade of a single to blank of stamped or molded material and which may be coordinated with particular facility with respect to the sheets to be typed. Another object is to provide a ribbon holder especially convenient in dimensions and propor 25 tions for compact packaging and which may be coordinated with a typewriting machine by a single thrust, without the need for further ad justing or fastening operations and will maintain the ribbon in correct correlation with respect “30 both to the platen and to" the imprinting type bars. Another object is to provide a ribbon holder of the above type which admits of a choice of al ternative positions for wear of different parts of taneous preparation of other copies in one or more contrasting colors. Another object is to provide a ribbon holder of the above type which admits of change from one color to another of any portion of any one or more of the copies without removal of the device from the machine but by a simple thrust. A feature of the invention is the use of a type writer ribbon frame to extend the length of the platen and provided with mounting portions at 10 the ends of said frame unitary therewith, and yielding means for retaining said mounting por tions in proper correlation with the frame of the machine. The yielding means may be uni tary with the carriage of the typewriting ma 15 chine but in certain advantageous embodiments this yielding means comprises a resilient arm or arms unitary with the ribbon frame and resil iently held with respect to a portion on the type writer carriage. tending in front of the platen, with ribbon mounting facilities at the ends thereof, or the arms of said frame may be curved for adaption to the curvature of the platen. unitary with the frame resiliently to engage the edges of the cover plates of the side frames, or 30 the resilient arms may extend rearward from the ribbon frame for clasping engagement about the platen. Another object is to provide a ribbon holder construction of the above type in which a plu _, rality of units identical in every way may con “) veniently be utilized simultaneously for produc ing a corresponding plurality of extra copies. Another object is to provide a ribbon holder of the above type which readily admits of prepara 55 tion of some of the copies in one color and simul In the latter case these arms hav— ing associated loops or stops for coaction with some ?xed part of the carriage, such as, for in 35 stance, a bail or bar to limit such ribbon frame against excessive movement in the rotation of the platen.

Fig. 1 of the drawings shows illustratively the carriage C of a typewriting machine which has side frames F between which is disposed a platen P. The primary ribbon 1' extends from one to the other of two ribbons spools B in front of the machine in coordination with the typewriting machine. 7 ' In-lieu of the usual carbon paper the present invention contemplates the use of auxiliary rib 30 bons, one of the frames therefor being shown in position in Fig. 1 at R. Referring to Fig. 2 which shows the details of the ribbon frame R, the frame may consist of a unitary sheet metal stamping comprising a lon 35 gitudinal bar 20 extending nearly the length of the platen, having downwardly extending arms or legs 2| ‘at the opposite ends thereof, each equipped lection of ribbon area exposed to impact. For this 15 purpose the support lug II, is provided with an extension II therebeyond, affording a rest edge ll therebelow preferably connected to the rest edge 22 by an inclined surface I2. Similarly the oppo site support Ol which is near the outer extremity 20 of the frame, is equipped with an additional rest ing edge N at lower level and adjacent arm 2|. the two rest surfaces 23 and I4 being connected by an oblique edge ‘I. Thus the frame affords in addition to the rests l2 and 33 shown in operative position in Fig. 2, additional rests II and I‘ at lower level and to the left of the first rests. The latter rests may be brought into operation by simply shifting the frame as shown in Fig. 2 to the dot and dash position in which the frame 30 would readily ride up along inclined edges l2 and 55 to bring rests II and 54 into operation, thereby elevating the ribbon preferably through approxi mately half the width thereof and shifting the same to the right through a corresponding range. ' ' By a thrust to the left the ribbon holder ‘could as readily be shifted from the upper to the lower position shown in full lines in Fig. 2. In the shift with a unitary ribbon clipping conformation 22 coacting with the ribbon clip 2! crimped to the . of the holder from one level to another, it is 40 corresponding end of the ribbon length 2‘. obvious that the ribbon is likewise raised or low 40 While the ribbon mounting clip of my prior ered an equal distance. By this means the width Patent No. 1,826,074 could be used to advantage of the ribbon may be considered as being divided in the present embodiment I have illustratively into a plurality of writing levels, and that the par ticular level of the ribbonv which it is desired to shown a modified form of clip, this clip compris ing a sheet metal piece 23 having its outer edge subject to the type impact may be located along turned over along oblique fold 24 presenting a free the writing line of the typewriter at the will of , edge 29 parallel to the folded edge. A notch 26 is the operator. In either of the two positions shown in Fig. 2 it provided through the fold 24 near the upper end thereof, and the metal above the notch 28 is bent is apparent that, the spring holders 36 are equally 50 inward on a fold 21 parallel to but spaced inward operative since the edge of the ribbon holder with respect to edge 24. which coacts therewith in either position of the The frame supporting arm 2| has an oblique edge 28 adapted to lodge in the sheath formed by the turned over part 29 and has a latch 28' pro 56 truding through the notch 26 and thereby e?ect ing the desired lock. The spring clip here dis closed is, of course, of more general application to ribbon holders of the type shown in my prior patent. The frame has lateral extensions 30 and II at opposite ends thereof, affording supports 22 and 33 respectively to rest upon the side frames F, with the bar R over the sheets and the ribbon 65 length 25 between two of the sheets, as best shown in Fig. 1. To retain the-frame in position with sufficient security during typing, there are placed on each of the side frames F of the carriage spring retain 70 ers best shown in Figs. 3 and 4. Each of these retainers preferably comprises a blank 'of sheet metal 36 extending longitudinally of the frame, having lateral ?anges 31 overlapping the sides of the frame and secured in position at one end by a 75 screw as which may be one of the screws that holder will be at the same level. By the present arrangement accordingly, after a ribbon has become worn in one position of use of the frame, the disposition at the other of the Q1 Gil two alternative positions exposes to the type im pact an entirely fresh area of ribbon at the lower half of its width and at a different portion of its length. The present inventionalso admits of effective 60 use of two-color ribbons, the choice of color there depending on the choice in the two alternative mounts of the ribbon holder. By the present arrangement it is immediately apparent that two, three or more of the ribbon holders could be used simultaneously to produce a corresponding number of copies, the frames 20 of all of said ribbon holders extending in front 'of the platen and of the paper, the respective ribbons extending between successive pairs of 70 sheets, and the spring ribbon frame retainers 36 all overlapping the entire series of ribbon holders. In such arrangement it will be apparent that all ribbon holders need not be used in the same one of the two alternative positions but some 75 3 2,088,448 may be in upper and some in lower position, de pending on the wear of the ribbon or the choice of color type wanted for the respective copies. As in the embodiment of the prior patent, the ribbon will be of such length that when in posi tion on the frame it will exert tension which the resiliency of the frame will accommodate thus to maintain the ribbon taut. While the use of a metal frame is generally de 10 sirable, advantages are obtained by making the frame of translucent or transparent composition A such as celluloid, phenol product and the like. The transparency of such composition affords the distinct advantage of avoiding any obstruction of vision at the cross bar 28. In the embodiment of Fig. 6 a frame of the general principle of that of Fig. 2 is shown, made wholly of a unitary piece of wire, corresponding reference numerals designating analogous parts 20 .in the embodiments of Fms. 2 and 5. The longi tudinal run 20' is reversely bent at one end to afford rests 33' inclined surface 55' and lower rest 54’ adjacent arm 2|’. At the opposite end the reversely bent wire affords rest 5|’ contigu N) On ous to inclined surface 52' and rest 32' from which extends the left arm 2|’. The ribbon frame of Fig. 6 is of such negligible width that it does not appreciably interfere with visibility. 30 Since the ribbon mounting clip of Fig. 2 is not adapted to the wire mounting arm, it is pre ferred in this embodiment to use a clip such as shown in Figs. 7 and 8. The clip 68 is crimped as at 8| to the ribbon length and has two integral protruding hooks 82 at opposite‘ edges thereof which become lodged in corresponding notches 63 in the ribbon mount ing arms of the frame. In Figs. 9 and 10 is shown another embodi 40 ment of ribbon mount in which the end-of each ribbon mounting arm 2la is flattened as at 84 and rivets 85, preferably two in number, a?lx the ribbon end to the holder. In this embodiment the ribbon is not removable in respect to the - simple wire holder frame, the unit being so sim ple and inexpensive that it is intended to be dis carded in its entirety after the ribbon is spent. If desired, a form of ribbon could be used which admits of re-inking to regenerate the unit. In Fig. 11 the ribbon is shown with a, unitary loop 10 stitched to the main length of the ribbon 12 as at ‘H. The loop is to be telescoped over the arm 2| b of the ribbon frame, which arm if desired may be provided with a notch 13 at its lower end to accommodate the width of the rib bon, which again is of such length as to exert strain upon the frame. In Figs. 12 and i3 is shown an alternative em bodiment in which the ribbon frame has a lon 60 gitudinal arm 88, ?nger tab 8| and ribbon carry ing arms 82 with latching means 83 generally similar to those of the other embodiments, ex cept for the fact that the ribbon carrying armsv in this case are curved for adaptation to the 65 platen as shown. Integral with the frame and extending rear ward from opposite ends thereof are spring arms 85 curved ‘away from the platen and preferably provided with an indented portion or hump 88 to straddle the bar 81 or equivalent instrumen tality which constitutes part of the standard construction of a typewriting machine. The free ‘end of each of the arms 85 extends in direction generally tangential of the platen and preferably has a loop 88 at its free end to engage the platen P. ’ Preferably the arms 85 are of such length and con?guration that as the arm 82 is brought cor~ rectly to rest against the platen, looped end 88 is resiliently forced past the maximum bulge of the platen and loosely engages the platen in home position as shown. Preferably the indentation 88 is somewhat wider than the bar to afford some freedom of back and forth movement for slight automatic shift of the ribbon ‘during typing‘which move ment is permitted due to the loose engagement of arm 85 with the platen as just set forth. The frame 80 is somewhat shorter than the distance between the side frames of the machine, thereby to permit freedom of displacement of the ribbon frame. In the preferred embodiment, in addition to the hump 86, one or more further humps at 89 - are provided. By this means there is afforded the possibility of setting the frame in two or more alternative positions relative to the platen to ex pose to type impact at will, either of two or more different regions of the ribbon width. 25 In this embodiment it will be seen that the ribbon frame is applied in position by a single thrust to retain the frame in coordinated rela tionin respect to the typewriter platen and yet to permit slight automatic shifting thereof dur ing action, thereby to lengthen the life of the ribbon by exposing to type impact ever chang ing regions of the ribbon. The bar 81 retains the ribbon frame however in such position as to permit ready rotation of the platen as desired without disturbance of the ribbon frame. In the embodiment of Figs. 14 and 15 is shown a conventional typewriting machine similar to that of Fig. 1, the side frames 98 each having the usual cover plate 9| which at its inner edge 92 protrudes beyond the carrying structure in the customary manner. The ribbon frame 93 is similar in general con struction to that of Fig. 2 or of Fig. 12, the rib bon arms 94 thereof being either straight or 45 curved to accommodate the platen as desired and having the oblique conformation 95 for mount ing of the ribbon clip (not shown). Integral with the outer edges of the arms 94 are resilient mount ing arms- 96 protruding forward and upward 50 therefrom with the free end 91 thereof to ex tend above the side frames. These resilient arms are corrugated as at 98 to resiliently engage ‘and overlap the free edges 92 of the cover plates for resilient mount of the ribbon frame as a body be tween the two side frames, for coaction with the platen. Preferably the upper edges of the corru gations 98 are oblique, as shown at 99, and the space between the successive corrugations is con siderably wider than the thickness of the cover 60 plate 9|. Accordingly, the frame can yieldingly shift to the left or to the right slightly within the resilient limitations of the arm and can shift upward and downward through a range limited by the width of the corrugations 98, thereby to vary the impact area of the ribbon. By affording two or more of the corrugations on each arm 96, as shown, choice of selection in the width of rib bon exposed to impact is afforded, as is readily 70 understood. While the ribbon frame is shown constructed and arranged to afford both limited longitudinal movement and limited peripheral movement, it will be understood that the constructional fea tures as described and claimed may be used’ to 75 4 2,088,446 advantage for either longitudinal movement alone or peripheral movement alone, and the frame .may be disposed even in relation immovable to the typewriter frame during use. ' It will thus be seen that vthere is herein de scribed apparatus in which the several features of this invention are embodied, and which ap paratus in its action attains the various objects of the invention and is well ‘suited to meet the re 10 quirements of practical use. .
