3 Claims.

This invention relates toa fixture for convenient attachment, particularly to a commercial typewriter having a cylindrical rotatable impression platen, for rotatively carrying a plurality or series of reeled transfer or carbon strips to be interleaved with continuous webs or strips of stationery for making manifold or duplicate copies.

It is quite expedient to use continuous or strip form of stationery in commercial typewriters having a cylindrical rotatable impression platen, these strips usually containing printed forms arranged in a consecutive order longitudinally of the strip, and the forms adapted to be consecutively torn off from the strip after the writing space thereof has been filled in or typed.

For making duplicate copies, carbon sheets are interleaved between a selected number of continuous form of stationery or work strips. In the use of loose carbon sheets difficulties are encountered in removing the sheets from a section or form length of the work strips that have been typed, and to transfer the same to a new position for writing upon a succeeding portion of the work strip. To obviate some of these difficulties, fixtures are employed providing a moving carrier to which one end of the carbon sheets are attached for withdrawing or pulling back the carbon sheets to position the same for a succeeding form or section of the work strip. Fixtures of this class are cumbersome, require considerable length to accommodate for the required travel of the carrier governed by the length of carbon sheet, and are burdensome to the carriage of the typewriter, and if wholly sustained thereon are very unstable.

Accordingly, a principal object of this invention is to overcome undesirable features of apparatus of the class referred to, and to provide a simple, light-in-weight, compact fixture readily and conveniently applicable in the preferred embodiment upon the carriage of a commercial cylindrical platen typewriter in which the manifolding or transfer medium is in the form of a strip, reel Wound, unreeled with the feeding advance of the work strips, with which the unreeled portion thereof is interleaved and re-reeled for withdrawing or retracting the carbon strip to reposition an unreeled portion thereof into a proper position with a succeeding portion or section of the work strips.

Another object of the invention is to provide a fixture for mounting upon the carriage of a commercial typewriter with one or a plurality of reels each carrying a strip of carbon paper adapted as unreeled to be interleaved with continuous stationery or work strips and travel therewith by the feeding influence of the typewriter platen, the reels under control and in transmission with a common actuator for simultaneously re-reeling the carbon strips and repositioning the same with succeeding portions or sections of the Work strips to continue the typing thereon.

Another object of the invention is to provide a carbon strip for manifold typing or writing con tinuous stationery or work strips, the carbon strip reel wound upon a spool for packaging and merchandising and with the spool insertable into a fixture for unreeling to interleave with continuous work strips and subsequently re-reeling the carbon strip to reposition the same between a succeeding portion or section of the work strips. and allow a tear-off for the portion or section of the work strip upon which the writing has been completed.

Other features and advantages of the invention are more fully set forth in a description of the accompanying drawings, in which:

Figure 17 illustrates the operatinglever unlocked, allowing the carbon strips of the several reels to be advanced and positioned between work strips.

Figure 18 shows the work and carbon strips engaged about the typewriter platen and advanced, thereby unreeling the carbon sheets and Inannerfor typing thereon. Carbon or transfer sheets or webs are interleaved between the several work strips in the customary manner for making manifold copiesof the typing impression.

The carbon or transfer sheets or strips for the number employed are carried by a reel mounted upon the carriage of the typewriter, each transfer sheet wound upon its own core or spool journailed within theframing of the reel. The cores or spools spaced for passing or threading the work strips therebetween for interleaving the carbon or transfer sheets and therewith extend to and about the impression platen of the typedata is being typed thereon.

writer, advancing with the work strips as the The reel comprises a pairof side frames 5, B of curved design in plan, each from a lower end having an angular bracket arm 1 extended therefrom downwardly and at an angle'forwardly, for attachment respectively to the carriage framing or to appropriate established points. on the carriage with which connections can be readily and securely made.

In the present instance theforward ends of both bracket arms are notched or slotted to socket over a rigid cross rod 8 of the typewriter carriage framing and rest upon a flange cross rail 9 5 of the carriage framing, as illustrated in Figure 5, and clamped thereto by a clamp plate l0 secured to the arm by a screw I l. In this manner the reel can be quickly installed upon and removed from the typewriter carriage and without "obstruction or interference to the operation of the Working parts of the typewriter carriage nor disturb the key shift of the impression platen. The side frames 5, 6 are connected by several cross rods !2, I2 for determinately spacing the same 3 and forming a rigid frame structure.

Each side frame is provided with a rearward extension 13 carrying a perpendicular depending guide bar I4 longitudinally slotted for slidably sustaining one end of a tensionroller l5 extending between the guide bar M of the reel framing,

and about'which the continuous w-ork strips are engaged and looped; as shown in Figure 5, for applying tension thereto. The work strips are advanced from a supply stack or pack when fiat packaged, as shown in Figure 1, or from a roll as another way in which this type 'of material is packaged for merchandising. The work. strips from the supply sourceare preferably positioned or stationed at a point below the reel to allow draping over a roller I6 journalled in the side frame of the reel framing at end of the extensions I3 of the side frames, thence extend downwardy over and about the tension roller l5, and thence upwardly to the reel.

The lowermost or first strip ll of the series which may be designated the original and outermost when threaded about the typewriter platen 3 extends from the tension roller l5 up- Wardly over a frame cross rod l2; thence forwardly over the guide roller I8 journalled in the lower forward end of the reel framing and continues downwardly to and about the typewriter platen 3.

The strip I! thus directly receives the typing the extreme impressions which is transferred to the second or other strips through the medium of the transfer or carbon strips interleaved between the work strips. The strips are pressed against the typewriter impression platen by tension or front and rear feed rolls I9, 20, commonly employed in to free the paper by depressing a finger key.

The frame of the reel supports and journals a plurality of spindles 2|, upon each of which a strip of transfer paper is reeled. The spindles are suitably spaced apart and arranged in an arc adapting the same to be transmittingly con-, nected or geared toga master gear for simultaneous rotation of all of the spindles.

As shown, the reel is provided with five spindles. The number, 'however is optional depending uponithe number of second strips for making the manifold copies desired from one typing- This is somewhat limited by the. capacity of the typewriter and the character of the. work, for if the typing is to be in definite spacing in which accuracy of registration between the corr'espond-' ing spacing of the several work strips is necessary, the number must either be reduced or frea quent relative, adjustment must be made to account for a differential in the advance of one work strip over another, primarily dueto. a

typewriting machines, and which can be released change in the feeding diameter caused by dispensing the sheets one upon another about a rotating cylinder.

Each spindle carries a spool or core upon which a strip length of carbon or manifold paper 22 is.

reeled and therefrom extended for interleaving between a pair of workjstrips, and therewith advanced with the feedingro tation of the typewriter platen. As the spindles and parts thereof are duplicate of one another, detailed'description thereof will be confined only to one of them. 7 r

A spindle 2| at its opposite ends is removably journalled in the side frames of the reel and as shown in Figures 7, 9, and 14, at one end is,

engaged through a support aperture in theside frame 5while its opposite end is engaged through an angular aperture 23 in the side frame 6, covered by a swinging closure plate 23 on the aperture side of the side frame 6. To remove the spindle from the reel'frame: it ismoved' axially untilwithdrawn from the journal aperture in the side frame 5'whence it can be swung to an angle toclear theside frame 5, and thence] withdrawn longitudinally from the side frame 6.

The spindle 2|.intermediate of itslength is provided with a spherical enlargement 24 serving 7 'plenishing.

as a fulcrum for a cylindrical core or spool 25 engaged over the spindle as shown in Figure 12. The spherical enlargement 24 is provided with a spring urged detent 26 projected radially therefrom for engagement into an aperture in the core for locking the core against longitudinal displacement and allowing the core to teeter upon the spherical enlargement.

A transfer or carbon strip 22 is wound upon the periphery of the spool 25, the spool preferably as a paperboard. product of low cost is employed in packaging the carbon strip for merchandising and provides convenience to the user. In renewing, it eliminates winding the carbon strip upon a permanent spool by the user which would be troublesome and possibly destroy the efficiency of the apparatus, for if carelessly applied it may be difiicult to maintain alignment with the work sheets.

In spooling the carbon strip, a considerable length can be employed accommodating for typing a number of form lengths of the work strip, before making a tear-off of the type forms and re-reeling the carbon strip for reuse be tween subsequent form lengths of the work strip, or if a tear-off is made for each form length of the work strip as typed consuming only a section of the carbon strip, it allows for a considerable reserve supply so that quite a number of worn sections can be torn from the carbon strip before the supply is diminished to require re- This offers a greater carbon capacity over the prevailing types of devices using the carbon paper in sheet size or lengths.

After the carbon strip has been unreeled from the spool the detent 26 will be exposed and can be easily depressed, as with the aid of a point end of a pencil, to release the spool for spool withdrawal. For inserting a spool, the detent is manually depressed to allow it to enter the bore of the spool and the spool slid over the spindle until the detent comes into registry with the orifice, whence it will snap into the orifice looking the spool upon the spindle. The teetering of the spool upon the spindle provides for a slight lateral adjustment of the strip without throwing a strain more toward one end of the reel than toward the opposite end, as well as accommodating for variations in tautness of reeling or pull when un-reeling which may tend to disturb the aligning traverse of the strip either when reeling or un-reeling. It thus serves as an equalizer, assuring more beneficial and efficient results than can be obtained by having the spindle rigidly or non-swayingly journalled.

The spool through the spindle is positively rotated for reeling or retracting the strip to withdraw the same from a type form or section of the work strips for reuse with a subsequent form or section of the work strip by a pinion 21 mounted upon one end of the spindle and in mesh with a gear 28 journalled in the side frame 5. The gear 28 is common toall the spindles oi the series for simultaneous transmission or control.

The pinion 21 is preferably loosely mounted upon the spindle and engaged or fixed to one end of a spring 29 encircling the spindle at one side of the pinion, and the opposite end of the spring is fixed to the spindle yieldingly connecting the pinion and spindle for a partial rotation of the pinion. The pinion is provided with a pair of spaced pins 3t-30 laterally extending from one side thereof for alternately engaging with a pin or lug 3| radially extending from the spindle between said pins, limiting or governing a starting or compensating partial rotation of the pin ion before the two parts are positively connected.

The master gear 28 is fixed to a stud shaft 32 journalled with and extending through the side frame 5. The outer end of the stud shaft is squared and carries a toothed or notched clutch disc 33 engaged with the square end of the stud shaft, and. straddled by a forked end of a hand lever 3 journalled or swiveled upon the stud shaft 32.

The lever 36 is provided with a spring-urged clutch bar or look plunger 35 slidably mounted within the hand lever, as shown in Figures 7 and 15. The lock plunger 35 is adapted to be engaged with a notch in the clutch disc for connecting the lever with the gear 28. The plunger has a knob 36 fixed thereon and extending laterally therefrom through an elongated slot in the hand lever for manually retracting the plunger to disconnect the lever from the clutch disc and gear 28. The plunger is also provided with a laterally extended pin 31 projected through an elongated slot in the hand lever 34 for cooperation with a latch plate 38 fixed to the outer side of the side frame 5 for locking the plunger in clutch connection with the clutch disc at one end of a manipulating stroke of the lever,10cking the master gear and pinions of the several spindles in connection therewith against rotation.

Referring to Figures 16 to 20 inclusive, diagrammatically portraying the carbon strip reel in various stages of operation and from which the mode of operation will be more readily understood, Figure 16 thereof shows the hand lever 34 in a downward position at the end of a manipulating stroke and locked to lock the spools and transmission mechanism therefor against rotation for loading the Work strips through the reel and to adjust the same with the carbon strips for bringing the forms into registry, and the carbon strips appropriately from the forward ends of the work strips. A necessary length or section of each of the carbon strips preliminarily having been un-reeled with their free ends brought into registry or alignment.

The Work strips in their order are appropriately threaded through the reel, the original or first strip extending from the tension roller l5 over the guide rod 12 and guide roller 18, and a second work strip from the tension roller l5 over the reel portion of the first carbon strip thence over the guide roller l8, and correspondingly in an order for the remaining work strips of the number employed, each second work strip being engaged over an appropriate reeled portion of a carbon strip to interpose or interleaf the carbon strip between two adjoining work strips.

After the loading adjustment has been made, the hand lever 35 is disengaged from the notch of the latch plate, whereupon the work strips and the carbon strips are free to be threaded about the typewriter platen to an appropriate degree for starting to type. The work strips and carbon strips with the rotating feed of the typewriter platen are free to traverse the carbon strips, unreeling, rotating the master gear and the operating handle 36 in a clockwise direction for the length of the form or section of Work strips to be typed. The hand lever, at the discretion of the operator, can be released from its locking connection with the clutch disc for any prescribed length of work strip to be typed, thus the strips can be advanced or fed to accommodate for typing upon several consecutive forms before making any readjustment of the carbon strips.

Assuming that the workstrips are advanced completing the typing. upon a prescribed form length and which it is desired when the typing is completed to tear off from the continuous strip, the hand lever 34 is engaged with the clutch disc and moved in a counter-clockwise direction as illustrated in Figure 19, and by releasing the tension, rollers of the typewriter and withholding retracting motion of the work strips, as. by manually grasping their protruding ends, the carbon strips can be retracted between the typed por tions of the'work strips and at the same time rereeled for positioning between a subsequent or succeeding form length of .the work strips.
