This invention relates to attachments for typ writing machines for simultaneously producing a plurality of ink copies.

The invention has in view a multicopy attachment providing an ink impregnated supplemental ribbon which is adapted to be interposed between sheets of paper arranged in a typewriting machine with the supplemental ribbon disposed in parallel relation with the typewriter ribbon for producing ink impressions on the sheets cor responding to the type impression on the original copy.

Another object of the invention is to provide a multicopy attachment of said character which is constructed and arranged for swingin movement to dispose the supplemental ribbon in operative position in parallel relation with the typewriter ribbon or in an outof-the-way inoperative position at one side of the typewriter to permit of the convenient insertion of the sheets of pap in the typewriter.

Another object of the invention is t provide means for the supplemental ribbon which normally spaces the ribbon from the sheets of paper so as to prevent smudging contact of the ribbon therewith and which engages the paper only when the type strikes the typewriter ribbon.

Another object of the invention is to provide means for spreading the ribbon guide means apart with the movement of the attachment into the out-of-the-way inoperative position and for moving the said guide means into close relation with the swinging movement of the attachment into operative position.

Another object of the invention is to provide a multicopy attachment of said character in which the supplemental ribbon is moved longitudinally within the guide means with the movement of the typewriter carriage from left to right for presenting different portions of the ribbon in position for producing the type impression on the paper.

Another object of the invention is to provide means for automatically reversing the direction of movement of the supplemental ribbon in the guide means for winding one end thereof on a spool and unwinding the opposite end thereof from another spool and vice versa.

Another object of th invention is to provide ribbon guide meansin the form of channels having longitudinally extending rectangular openings in the opposite faces thereof for engagement of the supplemental ribbon against the sheets of paper for receiving the typ impression thereon.

Still another object of the invention is to Pro vide an attachment of said character which can be conveniently applied to and removed from any standard typewriting machine.

Referring to the drawings by characters of reference, the attachment indicated generally by the reference character A is aflixed to a standard typewriter B which includes the usual frame l and keys operatively connected with the type bars |2 for striking movement of the keys against the ink ribbon l3. The ribbon I3 is trained through the ribbon carrier l4 and is disposed in front of the platen or roller l5 mounted for rotation on the reciprocatory carriage IS.

The attachment A consists of a head I8 having a rectangular frame l9 which includes a plurality of guide sheaths, two such sheaths 28 and 2| being shown in the present embodiment, in which two leads or

courses

22 and 23 of a supplemental ribbonM are arranged respectively for longitudinal sliding'movement. The sheaths 28 and 2| are formed with longitudinally extending slots '26 and 21 in the opposite walls thereof which slots are of a width to receive the type impression as the type strikes the typewriter ribbon. The arrangement is such that a plurality of sheets of paper trained around the platen or roller will extend upwardly across the sheaths with one sheet disposed in front of each of the sheaths and one sheet at the rear of each of the sheaths so as to produce two ink copies on the forward faces of two of the sheets and two ink copies on the rear faces of two of the sheets in addition to the original copy or type impression produced by the typewriter ribbon.

The head l8 together with the rectangular frame I 9 is mounted for swinging movement from an inoperative out-of-the-way upwardly directed position as shown in broken lines in Fig. 2 of the drawings to an operative position in which the rectangular frame I9 is disposed longitudinally of the machine and the sheaths 2D and 2| are arranged between the type guide 25 and the platen or roller l5 as illustrated in full line in Fig. 2 of the drawings. For such purpose the head I8 is pivoted on a pivot pin 29 journaled in pintles 38 carried by a plate 3| which is secur d to the right hand end of the carriage frame 32 by screws 33 or equivalent fastening means.

Afiixed to the head I8 is a forwardly disposed housing 34 in which two

gears

35 and 36 are mounted for rotation on

stub shafts

31 and 38 secured at their inner nds in openings in the rear wall 39 of the housing with the hubs 48 and 4| respectively of the gears protruding through openings in a partition wall 42 and forming spools on which the ends of the supplemental ribbon 24 are wound. From the hub or spool 40 the lead or course 22of the supplemental ribbon is trained through a slot 41 in the side wall of the housing 34 and thence extends vertically downward and through a slot 48 in the extension 49 of the housing 34. The slot 48 is disposed at an angle of 45 to the horizontal to turn the lead or course 22 horizontally into the open end 44 of the sheath 23 secured to the extension 49. From the hub or spool 4|, the lead or course 23 of the supplemental ribbon 24 is trained through a slot 58 in a spring latch 52 pivoted to the housing on a pivot pin 53 and to which spring latch the right hand end of the sheath 2| is afiixed.

From the slot 58 the lead or course 23 extends through a slot 54 in said spring latch which is located at an angle of 45 to the horizontal so as to direct the lead or course horizontally into the open end 45 of the sheath 2|. The said lead or course extends longitudinally through the sheath 2| and is trained about the outer periphery of a vertically disposed post 56 where it continues with the lead or course 22.

In order to drive the

gears

35 and 36 for winding the supplemental ribbon on the spools, a torque limiting reversing clutch is provided which includes spaced discs 51 and 58 having

pinions

59 and 60 disposed in meshing engagement with said gears respectively and which discs are mounted for rotation on aligned shafts 8| and 62 formed integrally with oppositely disposed

annular sections

63 and 64 of a roller 65 located between said discs. The shaft 62 is journaled for rotation in a bearing 66 in the head l8, while the shaft BI is a stub shaft'which projects through the partition wall 42 and through a cover plate 61 closing the outer face of the housing 34. A manipulating knob 68 is mounted on the protruding outer end of the shaft El and is provided with a bayonet slot 69 adapted to engage a pin 10 on said shaft for manually turning the same to wind the supplemental ribbon on the spools respectively.

The

sections

63 and 64 of the roller 65 are secured together by screws 12 and have their confronting faces annularly recessed so as to provide confronting

peripheral rims

13 and 14 on the sections respectively which rims are formed with diametrically

disposed slots

15 and 16 defining rectangular openings 11 and T8 in the periphery of said roller 65. A bar 19 is mounted for reciprocatory movement between said sections with the reduced opposite end portions and 8| of the bar disposed in said openings and adapted to protrude through either one or the other thereof. The slots 15 extend laterally through the walls and peripheral rims of the

sections

63 and 64, while the slots F6 are of a depth to extend partway through the rims of the sections whereby the

shoulders

83 and 84 formed by the reduced end portions 80 and 8| of said bar are adapted to engage against the inner periphery of the rims laterally of the slots 16 to limit the outward reciprocatory movement of said bar.

The bar 19 is engaged by a leaf spring 85 which extends through a transverse slot 86 therein with the ends of the spring disposed in oppositely disposed V-shaped notches 81 in the inner periphery of the rim 13. The said spring is bowed so as to resiliently maintain the bar 19 with the outer ends thereof protruding through either one or the other of the openings 11 and 18 in the roller 65. When the spring is bowed in one direction the reduced end portion 83 projects through the opening 11 as illustrated in full lines in Fig. 6 of the drawings and when the spring is flexed to the broken line position shown in Fig. 6 of the drawings, the reduced end 8| of the bar protrudes through the opening 18. When in the former position the spring is engaged against a stop pin 88 secured to the section 63 and when in the latter position, the spring abuts against a stop pin 89 carried by said section, the said stop pins and the notches 81 being disposed in alignment. The spring 85 thus operates as an overcenter snap spring which moves the bear 19 from one position to the other when the bar is 5. initially moved inwardly of the periphery" of" theroller-:65?

The-ban I9 is" formed with reversely directed cam: faces 92: and 93 at the ends thereof which are adapted to be engaged by lugs 94'- and 95 formed? integrally with the discs 51' and 58 respectively and which project laterally into overlyingv relation with. the rims l3 and 14" of the:

section'sifiitland 64'. Thelugs 94 and 95 are normally: disposed against the bottom: of the cam faces:92: and- 93 respectively when the. same pro"- trudesthroughlthe:openings 1.! .and 18 -in the roller 65* scr-as cooperatively connectione of the? spools 40zand;4.l with the shaft 62 for rotation to wind the.v supplemental ribbon. thereon. with: the. other spoolbeing free: to: rotate to permitofi the: free.

roller fidwhereby thelfull spool is rendered free to; rotate. and. the empty spool is operatively connectediwithithe shaft 62:for rotation to thereby wind the'supplemental ribbon thereon.

With. theshifting' of the carriage from left to right, the shaft 62 is rotated in a counterclockwise direction as viewed from the front of the machine by means. of a spring tensioned ratchet mechanism 98 operatively connected with a flexible. tape 99 secured at one end to theframeiof themachineadjacent the rear post I; The. ratchet mechanism 98 includes a ratchet wheel IflI securedto the inner end of the shaft 62 protruding into a housing I82. at the rear of the head I8. A spool lfl3 is rotatably mounted. on the shaft 62 at one side of said ratchet wheel and to which spool the other end of the tape 99 is secured and adapted to be woundthereon. A spring pressed pawl I04 pivoted:.to the. forward face. of the spool I03 is dis-- posed in engagement with the ratchet wheel IGI for. rotating. the same with the movement ofv thespool. in a counter-clockwise direction as the tape is unwound therefrom with the return of.

the carriage from left to right. Aspring pressed pawl IE5. is pivoted to the inside face. of the housing, I02 and engages the ratchet wheel IOI to prevent clockwise movement thereof. The spool I03is rotated to wind the tape 99 thereon by. a torsion spring, I06 which is disposed in an annular recess I B! in the side face of said spoolwith the inner" end of the spring secured to" the hub I08'and the outer end of the spring secured to a pin I9 carried by a cross-bar IID aflixed to'the'housing I 02 with the shaft 62 freely protruding'through' an opening iII therein to therebyretain': the spool I03 for free turning movement thereon. The tape $9 is trained through anopening I I2 inthe housing I02 and thence upwardlyover an idleriroller I'I3 with the upper endof the tapev attached to the peripheryof' thespool IE3: It will be understood that as the carriage is returned from left to right, the spool I03 will be rotated on the shaft 62 to play out thetape'99'therefrom with the pawl I04 engaging theratchetwheel IUI to rotate the sameand the shaft BZtogethen with the roller 65"with'the rotation'of" said spool. This winds the spring I06 withinthexspool- I03: It followstherefore that: each time the carriage is returned fromlefttto right, the shaft 62 is rotated to drive one of the gears 35- and 35 to'rewind the supplemental ribbon on one or the other of the spools 40 and. 4 I- as -:hereinbefore explained; Whenthe carriage.- is moved from right to left during the typing: operation; the spool I03 is: rotated on the-.shafti 62 by the'torsion'spring.

The sheath 2I is connected to the spring latch 52 for move-- ment to a spread apart relation as illustrated in Fig; 10 of the drawingswith the upward swing ing movement of the frame I9 from latched op erative position. The spreading apart of the: sheathsis to permit of theinitial' insertion of thesheets of paperv withreference thereto ashereinbefore; described. Thespring latch 52 1'spivoted in a bearing I2'I'carried by the carriage" frameand is engaged by a spring I 2!; to normally rotate the latchto'dispose the sheath 2] in the spread apart position. The latch is formed with a curved edge I29 which engages againsta stop bar I30 affixed to the carriage frame when the" frame I9 is swung downwardly towards latched operative position so as toswing the latch bar in its bearing I21 from the angular position shown in Fig. 10 of the drawings to the vertical" position shown in Fig. 9. The sheaths 'are'formed'i of relatively thin sheet material approximately" three-thousandths of an" inch in thickness'andthe same are of flattened tubular'formation so as to provide longitudinally" extending grooves I3I and I32 above and below'the' sl'ots26' and 21 in theopposite side walls thereof. Thesheaths are-adapted to be maintained in taut condition"- by adjusting the outer end II! of the frame I9- with reference to the top bar I33 thereof. is accomplished by turning the set screw I34 which is threadedly engagedin an opening the outer end II! and abuts against the endof thetop bar I33. The sheath 21 may also be tightened by-rotatingthe adjusting nut I 35 'which threadedly engages the pivot pin 53 protruding through the bearing I21.

The head [8 is adapted to be afiixed to any standard typewriting machine. For this purpose, the head includes a bracket I36 which is pivoted at its lower end on the pivot pin 29 between the pintles 30 as hereinbefore set forth. The shaft 62 is journaled in a tube I31 secured in a bore I38 in the split upper end I39 of said bracket which is provided with screws I40 for securing the tube in position therein. The ends of said tube are secured in split bosses MI and I42 formed respectively on the housings 34 and I02 by tightening the screws I43 therein. This spaces the housings 34 and I02 from the bracket I36 and permits of the use of different lengths of tube I31 for accommodatin different widths of typewriter carriages.

' The ends of the supplemental ribbon 24 are secured to the hubs or spools 40 and 4| respectively between a metallic sleeve I50 and a semicylindrical spring II. The hubs or spools 40 and 4| are formed with oppositely disposed notches I52 and the sleeve I50 and spring I5I are correspondingly bowed to engage in the notches I52. A cap I53 having prongs I54 frictionally engages in the notches I52 in overlying relation with the spring I5I for retaining the same in position.

Instead of the ribbon guides 20 and 2!, two ribbon guides I56 and I 51 may be provided as illustrated in Figs. 18 and 19 of the drawings which are fashioned from a flat metallic strip bent about the post 56 with one end of the strip affixed to the extension 49 of the housing 34 and the other end of the strip aflixed to the spring latch 52. The said guides I56 and I5! are formed with rectangular slots I58 and I59 opening medially thereth-rough substantially the length of the platen of the carriage and which slots are approximately the same width as the width of the supplemental ribbon 24 for slidably receiving the leads or

courses

22 and 23 respectively. The ribbon guide I56 is provided with cleats I60 and I6I secured thereto at the opposite ends of the slots I58 to thereby provide guide openings I62 and I63 through which the lead or course 22 is trained to extend longitudinally of said slot I58. The said lead or course engages through the guide opening I63 and is trained peripherally about the post 56 and longitudinally of the slot I59 through a guide opening I64 at one end thereof and through a guide opening I65 at the opposite end thereof formed by cleats I66 and I61 secured to the outer face of the ribbon guide I 51. The lower lon itudinal edges of the slots I58 and I59 form ledges I58 and I69 on which the leads or

courses

22 and 23 are supported in the slots I 58 and I59, the ribbon guides being of a thickness to prevent smudging or smearing contact of the paper against the supplemental ribbon when the paper is moved by turning of the platen relative to the ribbon guides as provided by the ribbon guides 20 and 2I The upper and lower longitudinal edges of the slots I58 and I59 retain the ribbon guides in position therein. The post 56 is secured at its opposite ends in a yoke I1I afiixed to the lower terminal of the outer end I I 1 of the frame I9.

In using the attachment, a plurality of sheets of paper fragmentarily illustrated as C, D, E, F, and G in Fig. 15 of the drawings are trained about the platen or roller of the typewriting machine with the upper ends thereof projecting above the platen or roller. The frame I9 is released from latched engagement with the spring latch II6 whereby the ribbon guides are spread apart as illustrated in Fig. 10 of the drawings. This permits of the insertion of the sheets D and E on opposite sides of the ribbon guide 2I and the sheets F and G on opposite sides of the ribbon guide 20 with the forward sheet C at the rear of the typewriter ribbon I3. When so arranged, the frame II9 is then moved to latched engagement with the spring latch H6 and the carriage together with the attachment shifted to the right in the usual manner for typing. When the sheets of paper are to be removed from the machine, the frame I9 is released from latched engagement with the spring latch H6 and rotated to its inoperative position where it is retained in upright relation by means of the stop lug I12 carried by the bracket I36 and adapted to engage against the underside of the pintles 30 for limiting the upward swinging movement of the head I0 and frame I9.

When only a single carbon copy is desired, a masking strip I13 of flexible material is removably secured to the forward ribbon guide in any desired manner such as by the pins I14 carried by the cleats I66 and I61 of the ribbon guide I51 which engage through openings in metallic ends I15 to which the masking strip I13 is secured at its ends. When the said masking strip is employed, the original sheet C is disposed at the rear of the typewriter ribbon I3 and a sheet of paper such as the sheet G is arranged at the rear of the rear-most guide 20 as shown in Fig. 15 or I 56 as shown in Fig. 19.
