and exact description.

My invention relates to attachments for supplying paper from a continuous roll or rolls to the platen oftypewriting machines, adding machines,and the like. I am aware that this has been done before, and I am also aware that some of the attachments for accomplishing this result use. devices for the-purpose of feedingthe paper at rightangles to the platen and keeping the same in register. Experience has shown that in some instances these devlces resist the effort to rotate the platen on its own axis or resist the reciprocable movement of the carriage of the machine in which the platen is journaled, and cannot be relied upon, in some instances with certainty, to feed the paper at right angles to the platen and always in register with each other. The consequence of these defects is, particularly when manifold copies are being made, to cause the print on the manifold copies to get out of place, or register, and oftentimes results in confusion that destroys the value of the manifold work as correct copies.

The principal object of my invention is to feed paper from one or more rolls having relatively stationary bearings, to the platen journaled in the transversely reciprocable carriage of a typewriting machine, or the rotatable platen of an adding machine, without twisting the paper stripsto such an extent as to resist the movement of the carriage or get the said strips out of register with one another. I

It is also an object of my invention to provide means for directing the movement of the paper strips to the platen at rightangles to the axis, thereof, and it is a further object to rotate the rolls simultaneouslywith and to the same extent as the platen, so that the intermittent forward movement of the said strips will be the same in every instance regardless of the diameter or diameters of the roll or rolls.

These and other objects I accomplish by the means hereinafter fully described, and

.as particularly pointed out in the claims.

In the drawings: Figure 1 is a side elevation of a typewriting machine having my improvements applied thereto and the stationary rolls of paper strips, and support therefor, partially broken away to illustrate the operation of said improvements. F 1g. 2 1s a top plan view of the same. Fig. 3 is a fragmentary side elevation of a sl ghtly modified form of my invention. Fig. 4: is a diagrammatic View ofthe loop of paper between the rolls and the platen and illustrating the twist of the samein two p0 sitions of the typewriter carriage.

For the purpose of convenience. I have herein illustrated and described my improvements applied. to a standard typewriting machine of the visible type, but my improvements are equally applicable to other makes of typewriters of the nonvisilo'le type, as well as to adding and billing machines, and to combined typewriting and adding machines of the usual design, or to book-typewriters wherein the platen is a flat stationary plate over which the writing mechanism is moved.

My invention, as shown in the drawings, comprises, in combination, a typewriting machine A, a table or desk B upon which sald machine is mounted, and a rack or frame for journaling one or more rolls of paper strips, together with mechanism. for connecting and accomplishing the coeperation of these three principal elements.

The typewriting machine may be of any of the standard construction, as above mentioned, having a revoluble platen 2 journaled 1n a transverselyreciprocable carriage 3, and the table or support for this machine may be of any suitable construction having.

afalse top 4 that extends a considerable distance to the rear side thereof and is prov1ded with atransverse slot 5 therein a suitable distance back of the rear of the desk.

The frame for journaling the rolls of paper strips or records? to be used in the typewr ting machine, comprises two vertical uprights 6, 6, arising from the rear extension ofthe top of the desk just back of theslot 5 therein, and suitably braced by braces 7, These frames are separated. a suitable distance apart and are provided with forwardly projecting lugs 8, 8, 'in which the journals of therollers 9 upon which the record-rolls 10 are wound.

In Fig. 1 of the drawings, five of these record-rolls are shown to be journaled, one

above the other, in uprights 6, 6, and the record strips are drawn downward therefrom in the same vertical plane throughslot 5 in the rear extension of the top of the desk to a point very near the floor and then said record strips are extended vertically upthroughsaid slot 5 to a point slightly above the plane of the typewriting machine where they are passed between guide-rollers 11, 11, and their coursechanged in a horizontal direction to a series of idle-rollers 12, 12, that separate each record from the others and direct them in a downward direction to and under the platen of the typewriting machine, for the convenient engagement of the typ Guide-rollers, 11, 11, are secured in upright frames orposts 13 secured to and arising from the rear ends of the extensions orbars 14, 11, the forward portions of which latter are screwed or otherwise attached to the side-frames 15, 15, of thecarriage 3.

Idle-rollers 12, 12, are journaled instandards 16 secured to' and arising from said bars 1 1 at the rear of the carriage.

The principal feature of my invention is the stretch of slack record strips between the feed 7 rolls and the typewriting machine. The maintenance of this slack during the operation of the typewriting machine is essential. In order to accomplish this it is necessary to provide means for transmitting the rotary movement of the platen to the rolls of paper, and to do this without said transmission means being affected by the longitudinal movement of the carriage. Said means comprise ashaft 17 whose axis is horizontal and parallel to the axis of the platen and which is located to the rear of the typewriting machine under the rear extension of thebars 14. Said shaft is journaled insuitable standards 18, 18, secured to and arising from the top of the desk upon which the typewriting machine is supported,

and these standards are located a suflicient distance apart to permit of the longitudinal movement of the carriage.

Shaft 17 is provided with alongitudinal groove 19, and a sprocket-wheel 20 is mounted thereon that has a tenon projecting inward from its central opening into thegroove 19 so as to permit the sprocket to move longitudinally on said shaft, but be rotatable therewith. Sprocket 20 is provided with an integral disk 21 on the side thereof adjacent to one of thebars 14, and this disk has a circumferential groove in its periphery, and this groove is engaged by v a finger 22 the shank of whichis secured,

preferably, to the extension of the left-hand bar 14, thus, as the carrier of the machine reciprocates longitudinall it causes thesprocket 20 to move longitudinally on theshaft 17 simultaneously therewith.

One end, preferably, the left-hand end, of

thejournal 23 of the platen has a milled hand-wheel (heretofore used for rotating the platen) removed, and a sprocket 24- securely mounted thereon which is connected by means of anendless chain 25 to thesprocket 20. These sprockets are of the same diameter, and thus when the platen is rotatedshaft 17 will rotate simultaneously therewith and to a corresponding extent.

The left hand end ofshaft 17 extends through its bearings and has asprocket 26 mounted on the same, and this sprocket is connected by means of a suitable chain belt 27 to asprocket 28 securely mounted on the adjacent end of ahorizontal shaft 29 the ends of which are journaled in suitable bearings orhangers 30 secured to the underside of the extension of the top of the desk.

Shaft 29 is disposed-in a vertical plane between the longitudinal edges of theslot 5, and about'midway of its bearings it is provided with afriction roller 31. The record-strips just below the slot'5 are engaged by this roller31 and a corresponding idle-roller 32, the shaft of which is arranged parallel therewith, and is journaled insuitable hangers 33 secured to the underside of the top 4 immediately to the rear ofslot 5. Theserollers 31 and 32 engage the recordstfips and through the medium of sprocket and chain mechanism, hereinbefore described, rotate. simultaneously and to the same extent as the platen, and draw the record strips downward from therollers 10 and maintain the slack of the recordstrips below the rear extension of the top of the desk all the time.

"If desired, the-slack of therecord-strips below the extension of the top of the desk may be inclosed by asuitable casing 34. The stretch 'of the record-strips hanging down from the guide-rollers 11 extends in asubstantially vertical plane to the bend of the slack portion thereof, and when the carriage of the machine reciprocates, assumes a slight incline in the one direction or the other, according to the movements of the carriage, but does not wrinkle or pucker, owing to the ability of the bend of the slack to tilt or twist in one direction or the other. This feature constitutes the principal improvement in this class of attachments,.and while this may be accomplished by other mechanism, I prefer to employ that hereinbefore described.

Suitable manifolding ribbon mechanism, such as are used in other devices of this character, are employed in order that the typewritten matter on the original sheet may be simultaneously written upon the man fold copies or record sheets. vices, as shown and described in prior Letters Patents of the United States, Numbers 812,177 and 870,336, granted to me February 13, 1906 and November 5, 1907 ,'respectivelv.

Such deare preferred, but of course it is understood that any well-known and adaptable mechanism may be employed for this purpose, and

I, therefore, do not deem it necessary toherein specifically describe the same.

In the modification disclosed in Fig. 3 of the drawings all the parts are substantially the same as in the form aboveIdescribed, except that instead of mountingthe parallel extensions 14' directly upon the carriage of the typewriter, a suitable frame X is substituted therefor that is mounted upon and carried byshaft 17, as shown. This frame X is adapted to be moved through the me dium of and longitudinally and parallel with thetypewriter carriage 3 by means of suitable arms Y that are secured to-thesideframes 15 of said carriage and project to the rear thereof, or by other suitable devices.

In order to assist in registering or alining the record strips after the same' have been threaded into the typewriter, especially when two or more record. rolls are employed,

I prefer to divide or. separate said strips, in their passage betweenguide 11 and the idle-rollers 12, by several transversely. disposed horizontal rods or rollers w, a, so that when the operator desires to adjust these record strips he holds the registered strips by clamping each betweenone of his fingers and the respective dividing rod and thereafter draws or pulls the remaining strip or strips under or past the platen until the same are in proper register with the others. After the record strips leave the platen they pass under a suitable cutter-blade andare adapted to be torn off in the desired lengths. For convenience in feedingthe paper strips and for rotating the platen, I prefer to mount a milled hand-wheel on the righthand extended portion ofshaft 17 so that by turning the same the platen will be ro-- tated bychain 25-- and the feed rollers 31 chine of the kind specified having a platen,

and 32 will be actuated through the medium of chain 27.
