T 0 all whom t may concern.'

Be it known that I, EDWARD THOMAS, a Citizen of the United' States, residin in New York city, in thecounty of New Ork and State 0f New York, have invented certain new and useful Improvements in Type- Writin Machines, Of which the following is a speci cation.

This invention relates to revoluble platen typewriting machines, in which provision- 1s made for collating work-sheets of various sizes and shapesin Various relative positions, preparatory to making simultaneous original and carbon type impressions on the collated sheets.

In the Underwood typewriting machines now manufactured for this purpose, the sheets are collated'by imp aling them upon a pair of endless bands provided with studs, to engage perforations or notches in the side edges of the work-sheets, and the collated sheets are advanced by means of said bands which run around the platen; the bands extending for considerable distance away from the platen to give room for collating sheets.

According to one form of m present invention, the sheets may be col ated upon a table in their natural reading positions, lthat is, face up and with the bottoms of the sheetsnearest the operative, and the use of the bands thus rendered unnecessary.

vIn carrying out the invention in the form herein disclosed, the platen of an Underwood front-stroke typewriting machine Iis lifted bodily by brin ing the rear side thereof to the top, and t e sheets are then laid upon the table, which is adjacent to the elevated platen, with the faces of the sheets uppermost and with the leading edges of the sheets lying u on the platen, and advanced far enough to e raspe'd by the platen feed rolls; the latter eing released during the collating of the sheets. Upon said table are placed studs advanta eously in two rows, one row along each si e of the table, on which studs the ksheets are impaled by means of the usual notches or perforations on the side edges. These studs are preferably disappearing, so that afterthe sheets are collated, thev stud-s are withdrawn as soon as;

such sheets are clamped to the platen by the rolls, thus avoiding danger of accidental disarrangement when transferring them from the control of thestuds to the control of the lSpecification of Letters Patent.

' `llthe sheets thereon just --studs relinquish their control' of the collat- Patented July 30, 1918.

platen feed rolls. The studs having been wlthdrawn, the collated sheets are now ,free to be advanced around the platenindependentl of the studs. In practice, the platen, whi e still elevated, may be rotated to advance the sheets around in the rear of and' forwardly under the platen.

Before dropping the platen to working pos1t1on, a iap may beclosed down upon the sheets; said flap preferably comprising two parts hinged one upon each side of the collating table vso that they canl be swung up for the collating operation.

At the operatlon `of dropping the platen to its working position, the collating table and its flap move with the platen; the latter preferably swinging from its upper collatlng` position to its `lower printing position, and the collating table and its flap swinging therewith; the movement of the table beying up-wardly and backwardly, and finally assuming preferably a standing position with a rearward inclination. The surface of the table andthe Hap or flaps, then form a table along which the collating sheets may typewriting operation.

Since some of the sheets may be too short to reach to the platen at the collating vopera.- tion, there are preferably provided upon the flaps, auxiliary feeding devices to press the sheets together 'sufliciently to make them advance properly'at the platen rotating operation. These feeding devices may be in the form of rolls mounted at intervals along the table to keep control of the short sheets after the studs lhave been withdrawn, and until they reach the bite of the platen and its feed rollwhich will be in some cases during the preliminary rotation of the platen, or before the latter has dropped to its printin position, and in some cases, after the actua printing operation has been done, and during the ine feeding movements of the platen.

Preferably the collatin pins have a mechanical connection with t e paper feed rolls which run upon the platen, so as to release said rolls when the collatin pins or studs are projected to their wor ing ositions, and, subsequently, to restore said eed rolls to working positions aainst the platen or efore the collatingl ing sheets lthis may be effected either manually or automatically. g

The revoluble platen of the Underwood typewriting machlnes are under the control of various line-spacing devices, including a line-space lever and pawl, and also including a detent and line-space wheel; and there is also provided a knob at each end of the platen, for rotating the platen indefinitely. It is desirable to keep the platen under control, not only when 1t is down in printing position, but also when it is up in collating position, and to be able to rotate the elevated platen by means of -a knob and under the control of the detent and linespace wheel. 1t is preferable to elevate the platen, however, without disturbing the location of the above describedline-spacing and platen rotating devices, and for this reason the line-space wheel, with the associated knob, is mounted 'upon the stud shaft in line with the platen aXle, and preferably, the knob, at the opposite end of the pla-ten, .is fast on. a corresponding stud shaft. These stud shafts have gears to mesh with a pair of pinions fixed upon the ends of the platen itself and correspond with the stud shaft gears. Hence,'pairs of gears extend from the ends of the platen to the stud shafts, so that the platen is always under control, and may be rotated one or more definite linespace distances, and there retained the same as if the platen were down at printing position, and as if a single axle served for both the platen and the line-space wheel and knobs. Therefore, one of the features of the invention consists 1n the provision of a collating table which, together with the platen may swing up'about the before-mentioned pinion shaft as a center to bring the table into collating position while the platen re- 40 mains under the control of one or both ward extensions knobs, and of the line-space wheel an'd detent, so that the platen may be rotated by the knob or knobs in line-space position, as required. vThe swinging up of the platen, it

.45 will be understood, brings the pressure rolls, which usually run upon the bottom of the,

laten, up to such a high position that the eading ends of the sheet can easily reach the same and occupy a position to be clamped thereby, without being too far advanced for collating purposes.

The paper shelf, which normally occupies a position at the rear of the platen, serves s when the platen is swung up `to collating position, as an introductory guide for the leading edges of the collating sheets, and may be made of celluloid or other transparent material, to enable the operative to see the sheets, and particularly to note whether they are within range of the platen feed roll.

This paper shelf may extend under the platen and up in front thereof when in l'printing position, and its ends may have upto direct the printing sheets upwardly and gver the top of the platen and between the surface of the platen and the pinion shaft, above referred to.

As the printing sheets advance up around the platen, they are deflected rearwardly by means of suitably curved wire fingers, and their leading edges then inclined back against the surface of the collating table; this being the surface which is underneath when the table is swung to collating position.

When the machine is in collating position, the leading edges of the sheets are directed by the wire or other guides, on to a third table, which is arranged upon the front of a typewriter carriage, and said sheets may advance along this table toward the front thereof and hang down in the front of the machine until the table and platen are swung back to working positions, when the advance edges of the sheets may be swung back against the table, and` then inclined upwardly and rearwardly.

The collating studs or pins on the table may serve either to impale the sheets or as side gages therefor. A .connectiom ineffective on the studs in writing position, may be provided to release the feed rolls, and this may be operated by the same fingerpiece as controls the studs.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

U per and lower characters 5 and 6 are,there ore, formed on the type-block 3.

The typewriter carriage includes the usual rotatable platen. 7, which, by connections hereinafter described, is adapted to be rotated in line-space intervals by the usual slide 9, which through the pawl 10, turns the line-space detent wheel 11. In order to accurately aline the platen at line-space intervals, the usual line-space detent 12 is provided to coperate with the line-space wheel 11. In order that the line-spacev w eel 11 may rotate the platen, said wheel is Xe'd to a stub shaft 13, provided with the usual knob 14 and journaled lin the frame 15 of the carriage, and said stub shaft is level to the platen, so that any rotation of the line-space wheel will rotate theplaten a. precisely equal amount. The gearing between the shaft 1'3 and the platen 7 includes a gear Wheel 16 fast on the stub shaft 13,'

and an identical gear -wheel 17 fast on an eX- tension 18 of the platen axle 19, said axle being journaled at each end in a supplementary swing frame 20. In order that the two gear wheels 16 and 17 may rotate together, they mesh with la single broad pinion 21, which is journaled above and infront of the platen 7. In order that the two ends of the platen may always move together, the opposite end of the platen axle' 1 9 isfsimilarly journaled' in the swing frame 20gand is geared te a Astub shaft 19* carrying a knob 14 (not shown), the connectionlbetween the stub Ashaft 19* and the platen shaft 18 in: cluding pinions 16, 17 and 21, which are identical with the other pinions above-ment'ioned. The two pinions- 21 are fast on acommon shaft 23, which is journaled in the l, position over the studs 29. line-space handle or lever 8 operating the eared carriage frame 15, and serves as a Ijournal on which the swing frame 20 swings. The shaft 23 is provided with a sleeve 24, which forms part of the swing frame 20. The swing frame 20, according to the present invention, not only carries the platen 7, but

also carries the usual front and rear pressure rolls 25 and 26, and a paper apron 27, which occupies a position, when the platen is in writing position, approximately that of the usual Underwood paper table and apron. For the purpose of writing, the platen `occupies approximately the position of the platen in an ordinary Underwood typewriting machineas shown in full lines in Fig. 1. For the purpose of locking the platen in this position to enable writing to be accurately and neatly done, the swing .frame 20 is adapted to be lockedV down by a pair lof catches 28, which are located adjacentv opposite ends of the swing frame 20, and are adapted to catch on studs 29 onsaid frame. In order to release these catches, there is provided at the left hand side of the machine, a handle 30 which forms an extension on one of the catches 28, and is able to re-' they are both fasten a common shaft 31,

Whlch is provided with springs normally tending to-hold the catches 28 in effective When the catches 28 are released, the swing frame 20 may'beswung up, thus car-, rying or rotatin a collating table 32, which is fast thereto, orwardly and downwardly to a convenient position for` the operative vto adjust worksheets-thereon. In Fig. 2 this position isshown as'horizontal, and at that angle collatin board 32 is supported by resting on rub ertipped bumpers 33 mounted on .the typewriter carriage.

Whlle the collating table 32 is coming around to horizontal position, pins 35 (which may be of the usual, Underwood collating type) are rojected through the eollating table 32, and

at the same time the `feed rolls 25 and 26 are moved clear oi the i platen. This enables'work- sheets 36, 37 'and 38 to be adjusted on the collating table by using the pins 35 either as impaling pinsto project through perforations 39 in the work sheets, or enables the pins 35 to be used as side or end ga es for adjusting said sheets. In thus adjustlng'them, one or more oi" the sheets may project u nder the apron 27,

which may be made of Celluloid to be transv parentfor convenience, and the sheets may project fartherv ast the rolls 25 and 26 around .under t e platen and out over Wlre paper-guides 40, which rise from in front of the normal position of the platen 1past around and behmd the sleeve 24, and

then forwardly to the front of the typewriter carriage, thus making it impossible for the leading edge of the Work-sheets to n bar of the carriage, rising therefrom at the ends and being bent so that it passes under the fingers 40. The apron 27 is provided with fingers 43 which rise above the printing line and near each end of the platen and substantially in line withthepins `35. These fingers 43 rise up high enough to guide the edges of the work-sheets above the ends of the paper guides 40, where they are adjacent to the platen. Since these long fingers lie outside of the printing zone of they platen, they do not interfere with the printing, although they lie considerably above the printing line. In addition to the work- sheets 36, 37 and 38 described above, there may also be inserted interleaved carbon sheets 44.

As was mentioned above, the bringing forward of the collating table 32 into collating position, automatically releases the feed-rolls 25 and 26 and simultaneously projects the pins 35. To accomplish this, there is provided on the side of the typewriter carriage frame a forwardly and upwardly extending cam 45, in which runs an impaling pin operating follower 46, which forms part of a slide 47, said slide being provided with slots 48 and 49, which slide respectively on pins 5() and 51, which, in turn, are respectively mounted on the swing frame 2O of the carriage, and on a bracket 52 fast on the collating table 32. The pulling forward of the collating table causes the follower 46 to be thrust upwardly along the collating Vtable rather rapidly, so that by the time the collating table has reached the vertical position seen in Fig. 5, the impaling pins are projected and the feed-rolls 25 and 26 are thrown ofi'. The connections between the slide 47 and the impaling pins 35 which enablethem to be thusthrown off, include a rack bar 53, which is formed as a bracket extension of the slide 47, said rack bar meshing' with a inion 54 fast to a shaft 55, which is journa ed at o positeends of the brackets 52, which are ast to` the collating table 32, and this shaft carries pinions 56 and 57 which mesh with corresponding rack bars 58 and 59 to insure a parallel motion of the pin-projectin slides 60, which will now be described. he pin-projecting slide 60 slides on the collating table 32, being provided for this purpose with slots 61 and 62,

which slide respectively on a shouldered pin 63 fast in a lug 64 on the bottom of the colf lating table 32, and on a shouldered pin 65 -feed-rolls 25 and 26, the feed-rolls areprovided with the usual mounting on the usual fast on a U-shaped projection 66, of the collating table near the platen. When this slide is moved away from the platen, diagonal cam slots 67 therein cam outwardly the pins 68, which are fast on the bars 69, said bars serving as mounts for the pins 35, thus the sliding of the slide bar 60 outwardly projects the pins 35, and it's return positively withdrawsjthexn. There is a bar `69 for each row of pins 35, and as will be seen from Fig. 4, each slide 60 controls a bar 69. For thepurpose of covering. up some of the mechanism, the outer surface of the slide 60 at the outer end ofthe collating table is turned up to bear against the under surface of the table 32. In order that the projection and withdrawal of the pins may simultaneously release and clamp respectively the shaft 70 of the Underwood feed-rolls, which, however, in the present instance, swings with the swingable frame 15. The usual roll release flat sided cam bar 71 is also provided, said bar being adapted to be operated by the usual rock arm 72. To cause the roll release cam bar 71 to be operated when the pins .35

are thus projected, there is provided a link 73, which is connected,to be operated by the shaft 55. To operate the link 73, there is provided therein a slot 74, which is engaged by a pin 75 projecting from the arm 72, with the result that the moving of the pin control slide 60, will shift the feed-rolls 25 and 26 into and out of their seizing position.

In order to hold the work-sheets against the collating table 32, when it is swung from the collating position up to writing position, there are.provided side flaps 76 hinged at each side of the collating table 32, and adapted when swung down to effective position against the work-sheets (see the lefthand or upper flap, Figs. 3 and 4) to bear against'said work-sheets byl means of feedrolls77. These' rolls allowthe top worksheet 36 to slide easily, so that the drawing of it along by the bottom work-sheet 38, will cause the'two work-sheets to travel together, because of the small friction between the top work-sheet and the rolls 77, which holds it in place. These fia s 76 are, for purposes of lightness and sti ness, made of light sheet metal with large portions thereof cut away and 'the edges 78 of the cutaway por-- tions turn up 'to form sti'ening webs.` The aps 7 6 are also provided with openings 79, registering with the pins 35 so that they may be folded down while the pins 35 are still projected. The iaps 76 extend down nearly as far as, but advantageousl' not quite to the paper apron 27 ;l thus serving to keep the work-sheets practically under continuous control of one or the other set of feed-rolls, the feed-rolls for this purpose being setlcloser together than the minimum length of any work-sheet likely to be used. If it be desired to withdraw' a work-sheet, while the collating table is in writing position, a handle 80 may be drawn upwardly and forwardly from the position seen in Fig. 8 to the position seen in Fig. 6. This handle is so connected to the rest of the mechanism that it casts olf the feed-rolls and 26 but is ineffective to project the impaling pins 35 when the collating board is in the Fig. 8 or writingposition. .For this purpose, a handle 80 is journaled near the end of the shaft 55, and moves against the tension of a spring 81, one end of which is fastened to the arm 72 the other end being fastened to a rock arm 82 fixed to the shaft 55. To release the feed-rolls the handle is Vmoved from the Fig. 8 position to the Fig. 6

position where the handle has moved against the tension of the spring 81 to be arrested by a pin 82a on the rock arm 82 and has' been effective #to move the feed-rolls away from the platen but has not been effect-ive to rotate the shaft 55 to retract the pins 35. From the above description, it will be seen when the table is thrown to collating position, that the rotating of the shaft 55 by the follower 46 not only positively projects the impaling pins 35- but also positively .throws off the feed-rolls 25 and 26, and

when the table is already in collating position the handle may be effective to throw o" the feed-rolls and project the pins and vice versa, but when the table is in writing position the handle 80 is effective only to throw otf'the feed-rolls. The handle 80 .it will be noted, is an extension ofthe arm 72 which carries the pin 75 of the pin-and-slot connection 74.

The feed-rolls 25 and 26 in the Underwood machine it will be remembered, are normally spring pressed against the platen, and in the present invention to return these feed-rolls against the platen When in writing position, there is the spring 81 between the handle 80 and the ar-m 82 which normally holds lug 83 against the arm 72 and tends to make the two move together. Wit-h the assistance of the springs which normally press the feed-rolls 25 and 26 against the platen, this spring is strong enough to return the feed-rolls against the platen. The spring 8l is however unable to project the impaling pins when the collating table is in writing position, owing to the fact that the follower 46 is positively held by its cam 45 with which it engages when in the writing position of the collating table.

In order that the feed-rolls 77 and the wings 76 which carry them may be detained strongly, either in their open or their closed position, the wings are provided with strong fiat springs 85 which lin the open position of the wings bear against the flat portion 86 on the under side of the collating table,

writing point of the platen around backwardly thereof. There is of course the same .planetarial motion in the reverse direction in returning the platen to writing position after collating thereon. In order to avoid any possibility of this planetary motion causing the adjusted sheets to be fed around the platen so rapidly as to tear them on the impaling pins 35, there is provided a device for automatically releasing the platen from its line-space detent so that the platen may be rotated by the work-sheet, in case the work-sheet is held too'long by the pins 35. To effect this result the ordinary Underwood line-space detent 12 (Fig. 9) is provided with the usual silenclng cam 89 and this cam-is automatically shifted to silencing spring 90 is normally ineffective, because a.

depending arm 91 fast on the swing frame 20 depresses the silencing cam 89 into its normal ineffective position against the tension of its spring 90 whenever the collating table is standing in writing position. The

Vnormal writing position 1s shown in fulllines in Fig. 9 and the silencing position of the detent 88y is shown in dotted lines therein.

As will be seen in Fig. 4, part of the platen swing frame extends as at 92 under the wings 76 and serves to prevent them from falling down into a dependent position.

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