g This invention relates to typewriting machines, and more particularly to means for inserting-into-xthe machine a pack of worksheets, the leading edge of which is so constitutedjthatgitmisctoo thick-to be inserted in the machine in the ordinaiy-manner.

In certain trades, in practice, there is used a pack of work-sheets or cards for conveying uniformly prepared datavfro'm'department to de artment. This pack may be made up 0 a pluralit of cards of various weights, textures and colors, having similar forms. Some of them, especially the thin sheets, may -have l e-enforcing paper rings glued around filing-holes that are punched in their leading edges; others may have cords threaded through similar holes, and all of the cards along their leading edges are suitably bound together, as

with Wire staples, to keep them in registration. A heavy leading edge for the cardpack, which heretofore has been found too thick to insert into a typewriter, usually results, thus necessitating the writing of the cards by hand One object of our invention is to provide means to make insertion of the pack into the machine practicable, sothat allthe data sheets may be typed simultaneously, the pack being capable of insertion into the machine and around the platen in substantially flat condition and caused to be fed or line-spaced in the usual manner by the feed-rolls which co-operate with the platen. I I

To accomplish these and other objects the platen is, in this'instance, made displac able upwardly in the platen-frame to a point where the bottom-ofthe platen is about on a level with the top of the platen-frame or carriage, thus not only leaving a space between the bottom ofthe platen and the usual feed-rolls which run upon its under side, but also permitting the front and back of the platencarriage frame to co-operate to serye as a rest or table uponwhich to lay the pack of cards and sheets, the leading end of the pack supported upon the front ba'rof the platen-carriage, and the bottom portion of the pack resting upon the rear bar of the platen-carriage. Thus the pack is readily laid between the, platen and the feed-rolls. The platen when so elevated may remain geiired to the usual line-spacing ratchetw eel.

.fiat condition upon the carriage frame.

When the pack is thusinserted, it may be in straight condition, and to facilitate the bending or wrapping of the pack around the platen properly as the platen descends totyping position, there is arran ed for cooperation with the platen a wor -guide or support which occupies an elevated position just in front'of the'platen and may stand; a little beneath the pack as: the latter lies in s the 'laten is pushed down, the pack is caug to by and tucked 1 down between t e platen and said guide or support, and caused to wrap itself properly around the platen as the latter com let'es its descent'totyping position, at whic point the usual bottom feed-rolls serve to press the pack up against the bottom of the "platen, to co-operate therewith in the subsequent line-feeding of the pack, or in the adjustment of the pack around the platen to bring it to position for typing the firstfliue' thereon. The space between said front ,work-guideor bar and t e rear bar of the platen carriage is only a lit 1e in excess of the diameter of the platen it- .self, sothat said front guide or bar co-.

operates with said rear, paper-apron in bringing the pack, which is sometimes very stifl, to proper position around the.

' platen.

. Said'front work-guide or bar is'preferably inthe'form of a feed-roll or'rolls, so as. to perform subsequent service in holding the pack back against the platen for the purpose oftyping thereon, and also to aid in line-feeding the pack, especially after the bottom edge thereof'has been advanced beyond the feed-rolls which run upon the bottomof the. platen.

Besides means for bending the pack around the platen, there are also provided means for squaring the pack, with the writing-lines on the work-sheets, parallel to the longitudinal axis-ofthe platen, simultaneously withits insertion nto the machine, means for holding the pack in its squared 1 position at all times during a typing operation, and means for holding the trailing edge of the work-sheets tight against the platen for typing on the extreme lower edge thereof. 1

, It is also usual to have the lower card, the one that lies nearest to the platen after insertion, made ofthin flexible cardboard typing operation.

and, to permit legible printing and typing on the card, to use cardboard with a slightly glazed surface. This glazed surface coming in contact with the smooth platen will render the comparatively thick pack liable to skew or twist in the machine during line-spacing, thus throwing the lines of typed matter on the forms out of parallelism. Another object of our invention is to provide means for not only gaging and squaring the card-pack upon insertion into the machine, but for retaining it in that squared or trued position during the entlre for one of the cards of'the pack also brings up the problem of binding the pack around the platen and means are provided for accomplishing this object so that fe ed1ng means may retain it in close proxim ty to the platen for typing matter thereon.

It is desirable and usual to have a plurality of writing-lines on the forms, and to have these writing-lines extend to the very bottom of the cards. Still another object of our invention is to provide feeding and holding means that. will retain thecardpack close to the platen in its t squared position, holding it both above and below the printin -point, until the very last writing-lines on the forms have received typed matter.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a plan View of the carriage of a typewriting machine with our mec anism, attached thereto, the parts being in normal position to begin a typing operation on a card-pack, which is shown inserted in the machine with the first writing-line of the form at the printing-point.

Figure 2 is a front elevation of the same mechanism shown in Figure 1 except that the card-pack has been advanced to bring the last writing line of the form to the printing-point.

Figure 3 is a plan View of the carriage of a typewritingmachine wit-hour mechanism attached thereto, the platen-swing frame being displaced to show the method of inserting the leading edge of a card-pack into the machine.

Figure 4 is a longitudinal, cross-sectional the carriage of the machine on the line 66 of Figure 2, the parts being in the position shown in Figure 3.

The use of cardboard a hole in another naeaaos 10, journaled in a swing-frame 11 which in-p eludes a front paper-table 12 and is mounted in a movable carriage 13. The carriage 13 includes a rear paper-table 14, which cooperates with feed-rolls 15 in guiding worksheets underneath and. around the platen 9, and an auxiliary-front paper-table or deflector 14, the use of which will be more fully explained later. The platen 9 is 1'0- tated by means of platen-knobs 16 through spur-gears 17, spur-pinions 18, and spurgears 19 which are fastened to the platenshaft 10. The swing-frame 11 is retained, with the platen in normal position, by hooks 20 which are mounted on the carriage 13 and which engage pins 21 on the swingframe 11. Journaled in the carriage 13 is a transverse shaft 22 on which are mounted brackets 23, which carry a transverse shaft 24, and brackets 25, which carry a transverse shaft 26. A feed-roll-frame 27, made up of two parallel end members 28 and 29 and two parallel transverse shafts 30 "and 31, which carry supplemental feed- rolls 32, 33 and 34, and Y-shaped clips 35 and 36,

- is mounted on brackets 37 on the transverse shaft 22. The feed-rolls 32' and 33 are fastened to the shaft 30, the Y-shaped clips 35 and 36 are fastened to the shaft 31, and the feed-roll 34 isloosely mounted on the latter shaft'on a collar 34. Arms 38 on the brackets 3T engage adjacent flat, cam surfaces on the transverse shaft 26 which is actuated by feed-roll releasing mechanism, not shown, to release the feed- rolls 32, 33 and 34, and the Y-shaped clips 35 and 36 from contact with the platen when work-sheets are being inserted into the machine in the ordinary manner. The end members 28 and 29 are preferably made of spring steel, and have primal-boxes 39 mounted thereon to receive the transverse shafts 30 and 31, the ends of which are tapped to receive retaining screws 40.

While this construction may be changed, without departing from our invention, itis the preferred form and allows the shaft 30 to rotate with the feedrolls 32 and 33, and allows the feed-roll 34 to rotate independently of the shaft 31, which, in turn, may have rotative movement with the Y-shaped clips 35 and 36.

- The end members 28 and 29 project below the shaft 31 and are caught behind the shaft 24, as at 41' and 42, in the manner shown in Figures 6 and 7, thus holding the feed-rollframe 27, when it is in normal position,

8, so that, when the feed-roll-frame 27 is in under additional tension with the feed- rolls 32, 33 and 34 pressing against the platen 9. The Y-sha' ed clips 35 and 36 are also preferably mac e of spring steel and have downwardly-projecting legs 43 and 44 which are caught behind the transverse shaft- 26, as at 45 and 46, in the manner shown in Figure normal position, the clips 35 and 36 will also be under additional tension against the platen 9. It will be noted here that" the printing-point- 47 of the machine lies ,between the feed- rolls 32 and 33 and the tops of the -Y-shaped clips 35' and 36. I

It will be seen from the above description that the feed-rollframe 27, including the feed- rolls 32, 33 and .34, and the Y-shaped clips 35 and 36, is inovably mounted as a unit on the brackets 37 and that it will move awa from the platen 9 as a uniti when actuate by the feed-roll releasing mechanism, which simultaneously moves the feed-rolls from enga ement with the platen 9. The feed-roll-l rame 27 can, of

. course, also be moved up to the platen by the releasing mechanism, after which the various feed-rolls and clips, except the feedrolls 15, will be brought under still greater tension than that exerted by the releasing mechanism by means of the independent spring-means described. It is important that-this increased holding power ofthe feed- rolls 32, 33 and 34 and the Y-shaped clips and 36 be-fully appreciated as these members play an important part in accomplishing the objects desired.

-Mounted'on the rear paper-table 14 are dupiicate adjustable paper-guides 48 having bodies 49 and upturned edges 50. Another set oiri ht and left paper-guides 51, which have bodies 52, upturned edges 53 and wings. 54, are adjustably mounted on the front paper -table 12. By referring to Figures 3 and 5, it will be seen that the paperguides 48 and 51 co-operating with the paper-tables 12, 14 and 14 form a chute, when the swing-frame .11 is brought forwardly and. downwardlyv to displace the platen 9 upwardly from the feed-rolls 15, for inserting the card-pack intothe machine.

Figure 3 particularly shows how the cardpack is squared with the platen ,9, by means of the paper-guides 48 and 51, before the plat-en 9 is lowered. Figures 1 and 7 show how the paper-guides 48 and 51 retain the card-pack in its squared position when the platen is lowered. A long, narrow cardpack 55, has, in this instance. an outer or top card 56 made of comparatively heavy paper with filing holes punched near the leading edge.

Second and third cards 57 and 58 are made of somewhat lighter paper and have single filing holesin the center,

near their leading edges, which are protected the cards, and are fastened to ether near their leading edges by wire stapfes 64'which hold the forms in registration with one another. It will be appreciated that the leading edge of the pack 55 will be quite thick due to the paper used for some of the cards and the presence of the wire staples 64 and the cord It is understood, of course, that the pack may beinterleaved with carbon-sheets or the sheets of a carbon-pack, that it may be of any desired dimensions providedit will fit'into the machine, that the number of cards may vary as may their weights, colors and textures, that any suitable forms may be printed on them, that any or all of them may be provided with protected holes, or cords, or both, or be left plain without holes or cords at all, or may have a plurality of such holes, and that any suitable fastening means may be employed.

In operation, the typist releases the hooks 20 and lifts the swing-frame '11 forwardly and backwardly until it assumes the position shown in Figures 3 and 6. The upstanding edges 50 and 53 of the paper-guides 48 and 51 now form thesides of a sectional chute, the top of which is the front paper-table i2, and the bottom of which is the flat surface of the rear paper-table 14, supplemented by the auxiliary-front paper-table 14", and the longitudinal axis ofwhich is atyright angles to the longitudinal. axis of the platen 9.

Inserting the leading edge of a card-pack 55 between the upstanding edges 50 of the paper-guides 48, it is pushed forward under neath the platen. and over the feed-rolis 32 and 33, in a straightened condition, until In "this position the [writing-lines on the forms are parallel to the iongitudin'al axis or the ipiaten 9. The chute thus serves a double purpose; that of facilitating the insertion of the cardpack 55 into the machine, and that of squaring the card-- pack with the plat-e119 simultaneously with the act of insertion. It will be noted that in raising the platen 9, the feed-rolls15, 32, 33 and, 34 and the V-sha edclips 35 and 36 have all been disengaged without operating the feed-roll displacing mechanism; in fact,

that mechanism need only be employed when the machine is being used for ordinary 7 work.

I of the platen in its descent, it will be notedother than in the desired manner.

that after striking the pack 55, it bends it downwardly around the feed- rolls 32 and 33,

and, as the descent continues, the teed- rolls 32 and 33 are placed vunder greater and greater tension, until, when the descent is nished, the pack is held closely against the.

platen, both above and below the printingpoint, and is ready to be typed upon. It

will also be noted thatfkluring the entire descent of the platen to normal, the pack 55 has been-held in its squared position by the paper-guides 48 and 5].. The feed-rolls 15'will now be placed, under ordinary tension, in contact with the card-pack 55, and the feed- rolls 32, 33 andB l and the Y-shaped clips 35 and 36 will be placed under additional tension by virtue of the spring-steel construction already described. The pack 55, as now held, cannot skew or be fed The parts have now reached the positions shown in Figure 7, and it will be seen that the chute mentioned above has been disrupted by the platen-returning operation, and now takes the form of two chute sections, one of which is formedby the rear paper-table 14: and

the paper-guides a8,lon the entry side of" said platen, and the other of which is formed by the front paper-table12 and the paper-guides 51, on the delivery side of said. platen. The chute, as now split into sections will continue to function as before in retaining the pack 55 in its squared position, with reference to the platen, as the pack 55 is advanced by line-spacing during the typing operation which follows.

The typist now types the required matter on the writing-lines of the form, advancing the card-pack 55 with. the'usual line-space mechanism until the trailing edge of the pack 55 passes by the paper-guides as. The additional pressure, alread mentioned as being applied to the feed-rolls32, 33 and 34 and the ,Y-shaped clips 35 and 36, is now useful in cooperating with the paper-guides x 51 in keeping the card-pack 55 from ing. c

Additional matter is typed on succeeding writing-lines until the trailing edge of-the card-pack 55 has passed by the feed-rolls 15 and 34, the tension of the remaining skew-- still prevent skewing? until. matter has been typed on that last writing-line. The 7 card-pack 55 is now ulled from the machine with the fingers, s owing every writingline thereon parallel, to the others: The swing-frame 11 is again released and raised, and the entire operation repeated for the next card-pack.

Variations may be resorted to within the scope of the invention, and portions of the improvements may he used without others.
