- To all whom it-may concern:

Be it. known that I, JOHN Z. Gnmizm's,

"citizen of the United States, and resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to typewrlting machines and its main object is to provide improved mechanism for producing at a. single operation a plurality of inked copies of the work.

To the above andothe'r'endS the invenv tion consists in the features of construction,

combinations of devices, and arrangements of -parts to be hereinafter described and particularly pointed out'in the claims. I

The present embodiment of my invention is more especially adapted for writing lists of addressesor the like. v

A portable support isarrangedat the rear of the typewriter cabinettor table, said support carrying in the present'instance four rolls of paper, the free ends whereof *are directed upward and over a guide on the platen carriage, and thence fed around the platen. Two auxiliaryribbons are mounted on spools'carried by the paper carriage, said ribbons extending lengthwise of the platen over the printing point and being interleaved with the strips or ribbons of paper drawn from the rolls. In the present instance two of these paper strips are of ordinary paper and two are thin tissue, the ordinary strips being lowermost, one passing be-' inal or first copies to be writtenat' once. In the particular system for which the presentmechanism was designed, one of'the copies. 'onordinary paper is intended to be pasted'on the magazineor pamphlet which is to be mailed, thesecond copy on ordinary paper is a reserve copy to be used in case of emergency. One of the tissue copies may be used for comparison oras a check, being compared. withthe original address was filed away, and the second tissue copy ispreserved in a safe place, as long at least as the subscriptions run of those whose names appear on it.

- The present invention is shown as. applied to a Smith Premier typewriter and while it was designed for use in the particular manner described it is nevertheless to be understood that it may be adapted to 'other styles of machines and may be used in a different way or ways and that parts of it may be employed without other parts.

main frame ofwt-he -machine is shown as Sing a I ,from' which rise corner lte'ferring first to Figs. 1, 2, 3, and 7 the posts 1 supporting a top plate 2. Fixed to the-top plate are ide rails 3 grooved to cooperate with anti-friction balls, said balls also cooperat-in withthe grooved front and rear bars of t ecarriage, said bars being numbered 5 and 6. The carriage, which isof the usual construction, also comprises side bars 7 connecting the front and rear bars- Mounted on the car'riage'is a platen frame or carrier of the usual or suitable construe-- ti'on comprising side bars 8 connecting front and rear bars 9 and 10. Journaled inthe side bars 8 -,is a platen axle 11 provided with axle 11'. Said platen may be of the usual construction and is provided with beads 11- finger wheels 12 and carrying a platen 13.

Since the paper strips or work sheets'in the present instance are comparatively narrow, about two-inches in width, the platen 13 may be made considerably shorter than the usual platen as shownand may bearranged at the middle'p'ort'ion of the platen wheel, said head 17 having a hub 19 through which passesa set .screw 20, securing the ratchet wheel to the platen axle. The

ratchet wheel 16 prevents lengthwise displacement of the axle and platen in the platen frame toward the right, while a collar 11*, suitably secured to the axle 11, contiguous to the inner face of the left-hand frame bar 8, prevents endwise displacement of the platen axle and the platen toward the left. The construction is such that the platen axle and platen may turn freely on the platen 'frame but'are held from movement lengthwise thereof; Line spacing devices comprising the usual spring-pressed pawl 21, rock shaft 2 2' and finger piece or handle 23 are employed, the pawl 21 cooperating with the teeth'of the ratchet wheel '16 to turn the platen for line spacing. The.

usual detent 24 may cooperate with the ratchet wheel '16 to maintain it and the platen in desired relationship with the platen frame. The frame bar '10 carries dependin arms 25 su porting a feed roller '26 whic is or may e of the usual construction but is short to correspond in length with the platen. The arms 25 carry at their lower ends a guide wire 27 which takes the place of the usual 1paper blade, the latter being dispensed wit as it would interfere with.

the arran ement of my improvements. A

' paper tab e 28 ma be provlded at the rear of the platen, an paper fingers 29 at the front of the platen, the paper table and paper fingers being mounted on the platen frame and being of, ordinary construction.

vThe carria e and platen are urged leftward across 1: e top plate by a spring drum 30, the leftward movements being controlled by escapement devices which are operated by the printing keys, said keysbeing connected with type bars which are circularly arranged on the topplatc 2. The escapc-' ment devices and printing instrumentalities are not shown in the drawings but it is to be understood that they are or may be of the construction found in the Smith Premier typewriter, or if preferred, may be of any other suitable construction.

A ribbon 31 of the usual width is supported on ribbon spools 32 arranged one at each side of the machine below the top plate, said ribbon being guided atthe printing point transversely of the printing line by a guide plate 33, such as is disclosed in the patent to Alexander Brown, No. 886,759 granted May 5th, 1908.. The ribbon spools are mounted on shafts 3B andare adapte'd to be connected in alternation with said shafts so as to feed the ribbon back and forth. The left-hand spool shaft is adapted to be connected with the spring drum 30 by thensu al pawl and ratchet mechanism and motion is transmitted from the left-hand spool shaft to the right-hand spool shaft by devices comprising a rod. 34. Fora full disclosure of the ribbon mechanism reference may be had to said Brown Patent No. 100

My invention "contemplates supplementing the main ribbon 31' by two auxiliary ribbons 35 and 36. These auxiliary ribbons are considerably narrower than-the main ribbon and are Wound upon a pair of double spools which are journaled on the front bar or rod 9 of the platen frame and between the ends-thereof. As shown in Fig. 5 each double spool comprises a hub portion 37,

outer flanges38 and a central intermediate flange separating the two ribbons 35 andplaten. Each guide memberis adjustably secured to a support composed of two curved plates or bars 40 which are arranged face to face and secured together by screw bolts 41 and nuts -12.-

As clearly shown in Fig. 4 the end portions of each pair of clamping plates 10 are tween the frame rods 9 and" 10 thesupporting plates 40 are curved downward so that the guide members may -tu1derlie the platen. The guide members are each clamped be tween their associate supporting plates 40 and extend inward therefrom toward each other. The guide members are ,preferably made of wire and each may comprise a main vpart 43, which is in the form of a long U- shaped loop, the open end portions .of which are clamped between the associate supporting plates 40.

Suitably secured between the .arms of the main portion 43, as by soldering or otherwise, are two "diagonally arranged closed wire loops 44 and 45. At the innerzend of the loop 43 is a transversely disposed closed loop 46 which may also be secured in place by soldering or the like. Between the loop 46 and the loop 44 a sheet metal protecting plate 47 is suitably secured to the main loop 43. Extending forward and slightly upward from the main loop toward the associate double ribbon spool is a guide arm 48. This armis U-shaped and its ends are suitably secured to the forward arm of the loop 43.

The ribbons 35 and 36 may be looped or hooked at their inner ends over pins'37 extending through the double spools parallel with the hubs thereof and close to said hubs. After'bei'ngwound on the spools said ribbons pass downward side by side from their spools at the rear sides thereof and are drawn over and around the front and under faces of. the front .arm or portion of the guide arms 48, thence extending rearward and being guided downwardthrough. the

diagonal loops- 44 and 45, the ribbon- 35 extending through the loops 44 and the ribbon 36 through the loops 45. The loops 44 and 45 serve as turning bars for the auxiliary ribbons, which leave said loopsat rightanglesto the directions at which they enter them, and thence are directed inward toward the middle of the machine, passing together through the loops 46 and under the plates 47, the ribbon 35 overlying the ribbon 36.

5 and breaking or roughening of their edges.

I have shown and describedone construction of guide members but it will be obvious 'thatthese guide members may be formed or made in different ways from the one dis-- closed. Preferably, however, they should be made of wire .as it has been found in 1 practice that the round surfaceof the wire prevents cutting or tearing of the ribbons It will be apparent that by loosening the supporting plates 40 the guide members will be unclamped or freed and may be adjusted both longitudinally of the platen and-also cirGunaferentially thereof after which they may be reclamped between the plates 40.

The auxiliary ribbons may be fed longitudinally from one double spool to the other by devices operating automatically. Preferably this feeding is accomplished, as inthe present instance, by connections operated by-the actuation of the-line spacing devices hereinbefore described. Secured to the in ner face of each double ribbon spool, as by soldering or otherwise, is a small gear wheel a Fi 1 2 and 5), said gear wheelbeing adapted to turn on the frame rod 9 as an axis. Each gear wheel 48 is formed with a hub portion 49 having a circumfen ential groove or depression 50. The gears 48 are adapted to mesh wit-h larger gear wheels 51. The gear wheels 51 are each provided with a hub or collar portion 52 which surrounds the platen axle 11 and receives a set screw 53, said set screw serving to fixedly secure the gear wheel to theplaten axle. The auxiliary ribbons are shielded from the teeth of the gear wheels 51 by the protecting plates 47 on the guide members. The two gear wheels 51 are fixed on the axle 11 so that they are nearer to each other than are the cooperating gear wheels 48, as will be seen from an inspection of Fig. 1. It

will be apparent therefore that only one of the gear wheels 48 fcan be in meshwith its associate driver 51 at a time.

\Vhen the linespacing handle 23 is actuated to turnthe platen through line space distances the gear wheels 51 will be turned,

and whichever gear wheel 51 isin mesh with its associate gear \vheelel-S will operate to.

tirely unwound from one of the double spools andwoundon the other, or as illustrated in Fig. 1, have been unwound from the left-hand double ribbon spool and wound on, the right-hand spool, it is necessary to reverse the longitudinal feeding mechanisi'u. This operat on 1111116 present instance 1s accomplished by shifting .the pair of double ribbon spools and their associate gear wheels 48 lengthwise'of the frame rod 9, so as to disengage, say, the 'rightrhand gear "wheel 48 from its associated-gear wheel 51 and cause the left-hand gear'wheel 48 to mesh with its associated driving gear.

7 The ribbon reversing devices herein shown comprise two arms 54 which are formed with slots'55 engaging the grooves 50in the gear wheel hubs 4:9 (Figs. 1, 2 and 5). .The arms 54 are horizontally disposedv and their rear end portions are perforated- 4 to "fit loosely around the platen axle 11 which serves as a guide. Forward of the slots 55 the arms 54 are perforated to receive a com nec'ting rod 56,- the ends of which are threaded for the reception of clamping nuts 57, there being a pair of said nuts ateach end .of the rod. Each of said pairs of nuts embraces the end portion of one'of the rods "54, thebonstruction being such that the rod 56 and the arms 54 are firmly secured in a 15 gle piece to shift the gears 18 and also fixed relationship and are movable as a sinserve to maintain said gears agfixed distance apart. The rod 56 passesthrough holes in the forked end portions-58 of a gu'ideflbracket .59, said guide bracket sur- -rounding theframe rod 9 and being suit-- 'abl'y'fixed thereto as by a pin 60. Between fthe forks or bifurcated end portions 58, .the rod 56; is provided with a finger-piece or. handle 61 at its upper side by which the "shift or reversing frame comprising the rod 4 56 and arms 54 maybe moved.

At the under side of-the rod- 56 between the-portions or fingers 58, a' detent spring" 62 is secured by a headed screw-'63, as best shown in Fig. 6. The detent' spring is formed with depressions 62 and"62 which cotiperate with the under edges of theiingers 58 to maintain th'e slidable rod 56 and the arms 54 ineither one of two predetermined positionsfi When the depression .62 in the spring is engaged with the left-hand finger 58, as show-n in Fig. 6, then the righthand gear 48 is in mesh with its associate gear 51, as shown in Fig. 1. If the handle or finger piece 61 be pushed. toward the right, the rod 56 will be moved longitu- I dinally rightward, causing the disengagenient of the depression 62- and' the engage-' ment of the depression 62 with the righthand finger 58. This rightward movement of the slide rod 56 shifts the arms 54 rightward, and said, arms at the sides vof the slots will engage with the sides of 'the groove 50 in the gear collars 49 and will shift-the gears/18 together with the doublespools fixed thereto, lengthwise along the. frame rod 9. The distance between the depressions 62 and 62 in the detent spring is so regulated that-the shift above described will cause the. engagement of'the left-hand gear wheel 48* with its associate gear wheel 51' and the disengagement of the, two righthand gear wheels 48* and 51, andthe parts will be maintained set in this new relationship by the detent until a re-shift is required.

to again change the direction of feed of the two auxiliary ribbons.

It will be noted-that in th'e construction shown thedouble ribbon spools are loosely mounted on the frame .rod 9. In order to prevent accidental turning of the disengaged doubleribbon spool and consequent slack in the free portion'of the ribbon, fric-- tion devices are provided, one for each double spool. In the present 'instance'sald disengaged double spool .will be compressed and the friction exerted by it on the outer face of the contiguous flange 38 will be sufficient to prevent accidental turning of the spool.

bons would also be slackened'or loosened if at any time the platen were rotated backward. In order, therefore, to prevent backwardrotation of the platen, a detent or pawl 24 is provided, said pawl being pivoted on otally mounted support 24 of the roller detent 24. The pawl or detent 24*,as will be understood from a consideration of Fig'. 4:, so codperates 'withthe'peripheral teeth of the line spacing ratchet. wheel 16 that said ratchet wheel cannot be turned backward or in reverse direction while the pawl is in operatlve posit1on','out when said ratchet wheel and. platen are turned in line spacing d1rec-' the ratchetwheel and will not interfere with the rotary movements. thereof.

As has'been stated, the work sheetspreferably employed with the present construction are'inthe form of continuous strips or ribbons of paper wound into rolls which are mounted to turn in a portable supporting frame. This frame may. be placed on the floor back of the typewriter table, said table being shownin Fig. 7 iand being designated .by the-numeral 65. The supporting frame also is shown in Fig. 7 and also in Figs. 8 to 10. It comprises a base: 66 which maybe of woosLand to which an upright U-shaped metal'frame 67 is secured by screws 68. The

frame 67 is of sufficient height to permit v ,fou'r rolls of paperto lie-mounted on it, one 120 above another and between its sides. I

As illustrated in Fig. 9 each roll of paper is mounted. upon a core piece or barrel 69 It will be obvious that the auxiliary rib-- a headed screw 24" secured in the usual piv- -tion the pawl 24 will slip over the teeth of of vwood or the like, said core piece being journaled on a headed rod or bolt 70 which is supported in the-sides of. the frame 67; At the end opposite its head, the bolt 70 is "formed with a groove 71 which coiiperateswith a slot 72 formed at the lower end of a slidabledatch 73 (Figs, 8, 9 and 10),.said latch being. provided with'an elongated slot 74 through which passes a headed screw 75 which takes into ath'readedopening in the frame 67 The construction is such that ,the

the latch 7 3 is in looking position the bolt 70 is held from endwise movement, and serves both as'a support for the associate roll of paper and also as'a tie-piece to prevent the walls or sides of the frame (37 from separating. Washers 76 are arranged on the rod) 70 between the inner faces of the frame 67 and the ends'ofthe: core iece 69 so that while the core piece and t e roll of paper may freely turn'on the rod/70, they are" prevented from slipping alon said rod and frictionally engaging .with tie inner walls of the frame 67.

As shown in Fig. 7 the loose'ends of the rolls of paper ribbons or worksheets are, led upward from underneath the rolls at the forward sides thereof. For descriptive purposes these paper strips orribbons are numbered 77, 78, 79 and 80, the two lower rolls 77 and 78 being of ordinary paper and the two upper rolls 79 and 80 being of thin tissue paper. Near the upper part of the typewriting machine at the rear side thereof, the paper strips are brought together and are passed for-ward over a guide member or roller, the detail construction where-- of is shown in Fig. 3. Said roller comprises adiollow sleeve orbarrel 81 provided with two flanges 82 spaced far enough apart to receive the paper strips. The end portions of the barrel 81 outside the flanges are slightly reduced in diameter, forming bearing surfaces which cooperate with the end portions of a rod 83 which passes through the-barrel 81 and is secured at it ends by headed screws 84 to arms 85. As shown in Fi 2 the arms85 are vertically disposed and at their lower ends are pro ided with open ended slots 86v whichfit between the teeth, of the usual tabulator stoprack-bar 87, said rack-bar being secured to arms 88 extending upward and rearward from the frame bar 6 of the carriage. Besides the receiving guide roller above described, the arms 85 carry a guide roller. of similar con struction comprising a barrel 89 and flanges 90. This latter guide roller is journale'd upon arod 91 which is secured at its ends to the arms 85 above the rod 83. After the paper strips or work sheets are led over the lower or receiving guide roller and fed through themachine and written upon, they are guided rearward, as shown-in Fig. 7,

over the upper guide roller and thence may pass downward behind the machine and H table into the basket or other receptacle, whence they maybe removed as convenient,

the inking rib being cut up or detached in lengths suitable .for handling.

In introducing the paper ribbons into the machine they pass over the receiving guide roller to the paper table 28 and thence downward between the platen and the feed roller 26, the latter during this introductory operation preferably beinglocked'away from the platen in released position in the usual way. At the under side vof the platen the paper strips are interleaved or threaded between the inkin ribbons, as illustrated in Fi 11, which shows the four paper strips and the three inking ribbons drawn to an enlarged scale. Between the main inking ribbon 31 and the lower auxiliary ribbon 36 'passes the lowermost paper strip 77 which,

as stated, is ordinary paper. Then between the two auxiliary llbbOllS 36 and 35 passes the second ordinary paper strip 78 and the lower one 79 of the tissue strips, said. strip 79 being above said strip 78. Then between the platen 13 and the upper auxiliary inking ribbon 35 passes the second tissue strip '80. When, rinting operations take place it will be obvious that the paper strip 77 will receive a positive inked impression from the main inking ribbon 31, the paper strip 78 will receive a )ositive inked impression from bon 36, the paper strip 79 will receive a negative or reverse inked impression from the inking ribbon 35 and the paper strip 80 will receive a positive inked impression from said inking ribbon 35. Thus it will be seen that all four of the paper strips will receive inked impressions;

that one which receives the negative impression being ofthin tissue paper may be easily read through the. paper so that the impressions will appear positive.

It will be noted that the rolls of paper are stationary and that the printed portions of the paper, after they fall into the receiving basket, may be stationary, while these portlons of the paper WlllCll are in the machine and which are being fed through the machine and over the guide rollers will move from side to side as the platen carriage is moved from side to side across the top plate. The paper, however, is comparatively narrow and the stationary parts of it are removed some distance from the carriage, and it is found in practice thatthe paper will not twist sutliciently to interfere with the free movements 'ofthe carriage nor willthe paper crease or wrinkle permanently or so as to detract from its appearance.

By my present'inventionl provide mechanism for simultaneously writing four inked copies, said mechanism-being combined with the-usual platen, platen carriage, paper feeding, line spacing and ribbon feeding devices ofatypewriting machine, and said mechanism comprising a support for a plurality of rolls of continuous strips or webs of paper, said support' beingpreferably stationary and arranged behind-the platen, a

receiving. paper guide for the continuous strips','said guide being on the carriage, a

pair ofribbon spools carrying a pair of auxiliary ribbons and mounted on the carriage, a ribbon guide for guiding one auxiliary ribbon over the other lengthwise of .the printing line, means for connecting said ribbon spools in alternation with the usual line spacing mechanism, and a paper guide on the carriage'forguiding the continuous strips or webs out of the machine, thecon ti-nuous strips as they passthrough the machine being interleaved or threaded onebetween the regular ribbon and one of the auxliary ribbons, two between the two auxli'ar'y ribbons'and' one between the platen and the other ofthe auxiliary ribbons. v It will-be seen that the auxiliary ribbon spools rotate in planes transverse of the platen frame, this rotation being-"effected by sets of gears each set of gears comprising,

a gear 4L8 and a larger gear 51., there being v two of these sets of gears 48* and 51, the sets being adapted to be rendered operative alternation. v

- My improved mechanism for duplicating =cop1es is comparatively simple and very eflicient, enabling the operator to write almost.

continuously and without pause for adjusting theparts or inserting fresh paper. The auxiliary ribbon mechanism is self-contained; that is tosay, it is confined between the end bars ofthe platen carrier or frame,

and none of-the parts" project outward or are-unprotected,.so that they are not liable to injury as in prior constructions.- .One of the auxiliary ribbons mayof course be em- ;ployed without the other, and variousv changes in arrangement and construction {may be made without departing from 'the sp'irit'an'd'scop'e of my invention.-
