'rrrnwnrrme MACHINE.

Application filed July 5,

of the general-type-disclos'ed in my Patent 1N0. 1,417,??72, dated May 23, 1922. In the ordinary operation of writing and forms on a t ewriter, a great deal of time is lost by aving to interleave the sheets with carbon paper and then setting the sheets in the machine preparatory to the Writing operation. Time is also lost by having to disassemble these same sheets after the typing is finished.

Also this is true in the ordinary method of filling out forms and simultaneously. making manifold copies thereof as, for example, in making out insurance forms by fillin in the necessar data in spaces rovided in rinted blan s, the original 0 the policy eing delivered to the party insured and one or more copies thereof being preserved in the files of the insurance company and the insurance agency. The usualoperation involves selecting from the filing case in which the form blanks are stored the 'required number of copies of the form blank, interleaving and assembling these blanks with the necessary number of carbon sheets and-inserting and positioning these interleaved and assembledblanksin the typewriter, all of which must be done before the work of filling in the forms is commenced, thereby consuming in preparation for the work a considerable amountof time in proportion to the time needed for the actual making out of the forms.

The present invention has, therefore, for a primaryobi'ect the provision of 'means whereby this use of time in selecting the sheets interleaving them with carbon-paper, assembling them together and insertin them in the machine may be reatl'y reduce and the required number'of prepared with a minimum expenditure of timeend eflortj v i Another ob 'ect-of-thsinvention is to 1'0- vide means w ereby a considerable .stoc of plain writing paper letter-heads, or blanks for each-cf a num er of-diiierent,=iorms,

; invention to uplicate copies 1922. Serial No. 578,080.

maybe conveniently stored and rendered quickly available for the purpose of preparing the required number of copies of a policy or other document from any of said forms.

It is also an object of the invention to provide means for iacilitatin the introduction of the required blanks, lb plain sheets, into th e. proper writing osition with reference to a typewriter, an for eliminating the necessity of excessive care on the art of the operator ordinarily required in setting up the work-sheets and transfer material to insure the pro er manipulation and operation of the mec anism.

It is a further object of the invention to provide a mechanism in which a considerable saving in carbon or transfer material is obtains and-in which there is required no handling of this carbon ortransfer paper by the operator so that soiling ofthe fingers and the resultant soiling o the paper is eliminated.

And it is a still provide a device of this type in which the operation of making erasures is facilitated.

With the foregoingund other objects in view I have devised the novel mechanism illustrated, in the accompanying drawings, in which Fig. 1 isa type of writing machine with my improvements complete.

Mounted on one-ofthe-end members, prefterebly'the left hendon'e' shown at Figs-3, 4,

(i ll and 7, are suitable supports for the supply of. transfer material which transfer material is preferably in the form of a narrow web 51, Figs. 3 and 4, and is wound in flat rolls of suitable size as indicated at 52. The supports for these rolls comprise studs 53 secured to the frame and carry a core 54 upon which the rolls 52 may be placed there being guiding and holding discs 55 and 56 mounted on these studs between which the rolls 52 are mounted. The core 54 is secured to the inner disc 55 and also secured to this disc on the other side thereof is the toothed ratchet or disc 57. The outer guide disc 56 is loose on the stud-53 and is yieldingly held against the end of the core 54 and the roll 52 of transfer material mounted thereon by means of a coil spring 58 secured on the studs by suitable nuts 59, with a suitable washer 60 between the spring and the disc. Mounted on the supporting means for the platen 33 is a toothed disc 61 adapted when the platen is rotated to reciprocate a bar 62. this bar being held at its lower end against the guiding pin 63 and in contact with the disc 61 by means of a spring 64 which is secured to the bar 62 at 65. This bar is pivotally connected at 66 to escapement elements 67, these elements being pivoted to the frame at 68 and connected so as to move simultaneously by means of a link 69 pivoted to the same at 66 and 70. These escapement elements are provided with spaced fingers 71 and 72 which are adapted to cooperate with the teeth of the discs 57 when the ratchet elements are rocked as the bar 62 is reciprocated and allow the discs 57 and the rolls of the transfer webs to which they are attached to rotate to supply the transfer webs as called for by the feeding! mechanism in a manner presently to be described. One of the escapement elements 67 is provided with a button 73 which may be pressed by the operator to engage the upper fingers 71 with the ratchet discs and hold the bar 62 out of contact with the ratchet 61 so that the platen may be rotated without affecting the esca ement mechanism.

1V ounted at the other end of the frame is a drum 74 upon which the used web may be wound. At the opposite end of this drum are the discs 75 and 7'6 and this drum may be rotated by hand by means of the knob 77. This knob and the outer disc are remoiably scoured to the drum by any suitable means such as a screw threaded engagement therewith. Also connected with this drum on the opposite side of the cod of the frame, is another drum or cup 78 within which is located a convolutc spring 79 frictionally engaging the inner walls of this cup as shown at 80, Fig. 8, and secured at its inner end to a shaft 81 rigidly connected with a gear 82. This gear meshes with the idler 83 which in turn meshes with the gear 84 secured to the platen so that rotation of the platen in the direction indicated by the a!" row in Fig. 8 will rotate the gear 82 in the same direction and will tend to wind the s iring T9. The friction of the spring against t e cup or drum 78 will also tend to rotate the drum 74 to wind the web thereon but, as there is frictional engagement only between the spring and the cup, the gear 82 and, therefore, the platen may if desired be rotated without feeding; the transfer web or webs across the front of the platen when the button 73 is depressed and the supply drums 52 are, therefore, held against rotation. The disc 76 is provided on its periphery with teeth 85 adapted to coact with a spring pressed pawl 86 to prevent reverse movement of the drum 74. The gear 84 is loose on the platen shaft 87 and is rotated counterclockwise as viewed in Fig. 8, or clockwise as viewed in Fig. 11, by means ofa toothed disc 88 secured to the shaft 87 and adapted to enact with a spring: pressed pawl 89 carried by the gear 84. It will thus be seen that' rotation of the shaft 87 counterclockwise asiviewed in Fig. 8, or clockwise as viewed iinFig. 11 will rotate the gear 84 therewith bin. the platen shaft ma be rotated in the opposite direction wit out rotating the gear.

The transfer webs are guided in the passage from the supply drums o-r rolls of web 52, Fig. 3, across the front of the platen to the drum 74 by suitable guiding means. At

the left hand of the platen, as shown in;

Fig. 3, and mounted on the end of the frame is a hollow pin or tube 106, Fig. 13, pla ed at an angle of substantially 45 and wlun a single carbon copy is made the single transfor web required is passed from either supply drum under the guide pin 108, Fig. 3, and then around the outside of the tube 106, as shown in Fig. 13, and then goes between the guide fingers 109, Fir-. 3, horizontally across in front of the platen 33, as shown in Fig. 3, over another guide 11.0 placed at 45, undcr a second guide pin 111 and then to the drum 74. make two carbon copies two transfer webs are required and as they are both wound up on the drum 74 the outer web 112 must travel slightly faster than the inner web. If those webs are both passed over the guide tube 106, Fig. 13, in con act with each other, as the outer web moves slightly faster than thc inner web and it cannot pass the inner web it will cause this inner wcb to slacken in front of the platen. Therefore. to prevent this l provide a so aratiug; means prefcrably an additional guiding means as shown n Figs. 13, 14. and 15 comprising a pin 113 adapted to be inserted in the upper end of the. guide iubc 106 by means of a knob 114. This pin carries a semi-circular shield 115 spaced from the pin 113 a suitable amount However, when it is desired to 101 norm ally so that when the pin 113 is inserted in the tube 106 the inner surface of this shield will be spaced from the outer surface of the tube to allow the passage of the inner web 107. The outer web 112 passes around the outs de of the shield U5 and so is maintained out of contact with the inner web.

Secured within the frame above the platen is a guide plate 90 having guide fingers 90' secured thereto adjacent its upper edge and extending upwardly in front of roll l9. The plate is provided with vert cal Slots 91 adjacent its opposite ends in which is adjustably mounted a knife blade 92 by any suitable means such as the nut 93, Fi 12, threaded on the sleeve 94 which has a ange 95 bearing against the front surface of this plate. By loosening this nut the knife may be adjusted in the slots and then secured in adjusted position. Mounted to rotate in the sleeves 94 are pins 96 provided in their surfaces with a spiral groove 97 and the knife blade 92 is adapted to slide longitu dinally of the sleeve 94 on the outside thereof as shown in Fig. 12. The sleeve is provided with a longitudinal slot 98 through which lug 99 carried by the knife blade projects, this lug also extending into the spiral groove 97. Rigidly secured to pin 96 by any suitable means as a screw 100 so as to move with this pin, are guide fingers in front of the plate 90 as shown in Fig. 3 to hold the free ends of the sheets of paper in an upright position after they come off the platen. The knife blade 92 is normally spaced a distanee'forwardly of the plate 90 as shown in Figs. 5 and 12 to allow free passage of the sheets of paper. When it is desired to sever the sheets of paper the operator presses the knife blade inwardly and clamps the sheets of paier between this blade and the plate 90. 'l is operation, through the action of the lugs 99, Fig. 12, in the spiral grooves 97, rotates the pins 96 and swings the guide fingers 101 outwardl toward the ends of the frame leaving t e space in front of the sheets of paper free and unobstructed so that these sheets above the knife blade may be torn oil along the upper edge thereof. Upon removal of pressure from the knife it is moved outwardly to its normal position by the springs 94 which movement also returns the guide"fingers .101 to their normal upri ht positiorl in front of plate 90.

When the carrier is removed from the machine the free ends of the paper should be secured to prevent their dropping away from the platen to be sure that they are always in proper writing position when the carrier is mounted in writing position on the carria Various means may provided for oing this but I hays shown the spring elements 102, Fig. 3, pivoted to the knife blade 92 at 108 and being bent be the top edge of the knife rearwardly so that, when in the position shown in Fig. 3, they may project throu h elongated openings 104 in the knife bla e and clamp the free ends of paper against the plates 90. These springs may be pulled forwardly and moved to one side of the openings 104 and thus release the paper by means of suitable handles or knobs 105.

The operation is as follows:

When it is desired to use this attachment, the regular platen 23 is removed from the carriage 21 by sliding back the guides 26 and lifting the platen from the carriage. This attachment or carrier including the frame, platen, work-sheets, transfer material, and means for holding and feeding the same, is placed on the carriage in place of the platen that has just been removed, the platen 33 in the attachment occupying the position of the old platen 23 enacting in the same manner with the type bars and adapted to be rotated by the spacing mechanism 40 in the same as was the old platen. As this platen is rotated, it draws from the rolls 49 the paper P the free ends of which have been passed around under the platen and properly located with respect to the trans er webs and then passed between the knife 92 and the guide plate 90. Rotation of the platen step by step in the writing operation will rotate the drum 74: through the gears 82, 83, S4 and the spring 79, Fig. 8, and wind 11 the used transfer web as fast as this we is released by the escape- Inent mechanismpn the supply rolls As this escapement mechanism is operated by the rotation of the laten, if it is desired to advance the work-sheets for any reason by hand, this may be done by means of the knobs 38 in the usual manner. However as it is undesirable when doing so to advance and thus waste the transfer web, the operator by pressing on the button 73 may hold the supply drums against rotation and the spring 79 will then slide relative to the cup or drum 78. It will he apparent that as this drum is rotated through the instrumentality of the spring after it. is wound or placed under tension, the transfer web will always be held under tension from this spring and so will always be held taut across the front of the p aten. After the writing has been complet the sheets may be advanced as just descri d to the proper tearing ofi position, when the operator resses against the front edge of the knife lilade 92 clamping the sheets against the guide plate 90 and moving the guide fingers 101'from in front of the sheets to the opppsite edges thereof. The sheets may then sevfiree by blade. The knife blade being then released is moved to its forward position and the guide fingers 101 are turned to holding position as shown'in drawing them forwardly over Fig. 3 by the springs 94. If now it is dcsired to remove the attachment and use the old platen. the holding springs .102 are placed in holding position, the slides 26 moved To releasing position and the entire attachment removed from the machine by lifting the same from the carriage. In using the old form of platen. holding clips are usually provided at the front thereof such as pivoted plates U7, Figs. .ic and 16, carrying rollers 118 and yieldingiy held against the platen. I have provided means for holding these clips forwardly so they will not interfere wilh the insertion of the platens, such angle shaped elements 119 secured to the carriage at 120.

It will be apparent from the foregoing description that the carrier including the platen. supply of worksheets and transfer material may be readily applied to and re moved from the machine WltllOlll the use of tools of any kind, and that as the Worksheets and transfer material are all set up in the attachment and are in continuous rolls, assembling and setting up of the individunl sheets is unnecessary and the time re uired for these operations which is consi erable is eliminated. Also as there is no handling of the transfer material by the operator there is no soiling of the fingers or the work-sheets. Further, as he transfer material is in the form of a narrow web and is fed across in the front of the platen in a direction transverse to the direction of feed of the Work-sheets, if any erasures are re quired' they may be made by slightiy advancing the Work-sheets and performing the erasing operation without the necessity of inserting a guard between the transfer paper and the carbon copy. There is material saving in the amount of transfer paper required as all the transfer paper is used uniformly, the feed thereof being proportional to the amount of writing donc instead of the amount of work-sheets and paper passed through the machine as in the ordinary method.

In the typewriter employed the regular platen is rcadilv removable from the re ciprocating mechanism and in my device the carrier unit comprising the platen. worksheets. and carbon paper or transfer niaterial is adapted to be connected with the said reciprocating mechanism of the typewriter. which includes a tension and escape,- mcnf mechanism, by the some m ans. so that this carrier is also readily removable to allow the operator to quickly and easily con neck this carrier unit with and disconnect it from said reciprocating mechanism. thereby making the carrier unit freely interchangeable with the reguhn platen provided.

on the machine. The connection or relation between the carrier unit or the regular platen carried by the machine to the recipl'UCHl ing nuchenismis such that the carrier unit or regular platen may be readil disconnected and removed therefrom without breaking down the recipocnting mechanism.

In short in applicants device the carrier 7 unit and the regular platen are freely interchangeable and one may be removed from the typewriter and the other placed in posi lion thereon without breaking down any part of the typewriter, carrier, or regular 15 platen. or changing either one in any way.
