9 Application filed August 7, 1917. Serial No. 184.820.

in an attachment for typewriting maehii'iesa and more especially to acollating device for assembling work-sheets to he written on at different. relative points. This case is an improvement on my application. No. 180,530. filed July 14, 1917.

In the present case, the sheets are as sembled face upwardly at the front of the platen on the collating portion of a paper 'arrlel' or eollatin; frame, which is main-' tained in a position wrapped around the platen. and may he oscillated bac and forth by rotating the platen.

For the purpose of positioning the assembled sheets on the platen, and carrying. them line by line in a normal typewriting operation. the frame may be provided with two series of studs. so that. the work-sheets.

which have corresponding openings in their side margins. may he impaled on the studs 'to properly position them relatively to each other and to th eollating} frame,

The \\'orl\'sheets. after they have been placed on the collating frame, are preferably utonaitically fed around the platen in a reverse line-space direction. by means of a spring connected by suitable mechanism to one end of the collating frame.

This automatic feed may he under the control of a finger-piece or releasing key connected to the line-space detent and the feed rolls, l nder normal conditions. the automatic feeding of the platen may he prevented by the line-space detent and the pressure of the. feed rolls.

Automalically-operated means, controlled by an adjnstahlestop on the collating frame, may be provided for limitin; the reverse feeding movement of the collating frame withlthe work-sheets thereon to stop the rotation of the platen when the tirst printing dine, Qt'the work-sheet reaches the printingpoint. 'lhis stop may he also etl ective to trip the finger-piece or release key, so as to bring the feed rolls and detent into play when the work-sheets have been properly positioned for printin The collating frame is flexible andis guided around the platen in a U-shaped path. It may have in addition to the spring connected to its one end for automatically feeding it around the platen,-an0ther spring connected to its other end; the power of which is less than that of the first spring,

and sutiicient to keep the collating frame taut. but not to counte'act the action of said first. sprin".

The body portion of the collating frame may act as a backing" for the work-sheets. This frame is detachable so that it may be conveniently removed from the machine and replaced by another when the body portion becomes worn, or damaged by the types.

Other features and advantages will hereinafter appear.

In the ata-(mipanying drawings,

Figure 1 is a perspective view, showing the collating frame in a position to receive the work-sheets to be assembled.

Fig. 2 is a side ele 'ation, with the parts in the position of Fig. 1.,

Fig. 23 is a view similar to Fig. 2, except that the pressure feed-rolls and the line space mechanism detent have been released, so s to permit the easy reversal of the collating frame and platen, for the purpose of placing the work-sheets on the platen after having been collated.

Fig. l is a view similar to Figs. 2 and 3, partly in section. the collating frame having been moved downwardly at the front with a reverse. rotation of the platen, so as to place thev assembled work-sheets on the platen,

and the. stop carried by the frame having tripped the pressure feed-rolls and line The platen 1 is mounted on the. usual platen axle 2, which, in turn. is mounted in an inner carriage or platen frame 3. platen 1 is rotated for a number of line spaces by the usual knobs 4 provided on the The end of the platen. axle 2. It also may have their released position avl'ien they line-space movements by means of a linespace mechanism, indicated n1 'eneral at 5,

andiucluding a linespace wheel 6. This mounted on swinging frames 12 and 13, so.

as to be adjusted toward and from the platen '1,

Normally, the pressure feed rolls 10v and 11 are held. in intimate Contact with the platen 1 by means of springs (not shown).

. To release these pressure feed rolls, there is provided a finger-piece 14, which, when depressed, draws on a link 15 to rock a bell crank 16 secured to a shaft 17. The shaft 17 is provided with reduced portions 18 normally engaging their flat sides with arms 19 and 20', provided on theframes 12 and 13 carrying the pressure feed rolls 10 and 11.

The rockin of the shaft 17 s )reads the arms ,7 h 19 and 20 apart, thereby withdrawing the pressure feed rolls 10 and 11 from engagement with the platen 1.

The pressure feed rolls 10 and 11 can be released from another point, which also disengages the detent- 7" from the line-space wheel (3. This includes a hand-lever 21, which, when depressed, pulls up on a link 22 to swing upwardly a platen release 23 engaging the detent 7, This release forces the roll 8 out. of engagement with the teeth of 'the line-space wheel 6,

The release 23 is connected by a link 2i to an arm 25 on the rock shaft 17. Thus, the hand-lever 21 can release the detent 7, and at the same time rock the shaft 17 to release the pressure feed rolls 10 and 11. The reduced portions 18 on the shaft 17' act to lock the feed rolls in i a operated from thevfinger-piece 14 or t handlever 21. T his, also locks the detent 7 in its release position, until either the hand-lever .2l. or the lingerpiece 1d is returned to its normal position.

For the purpose of asseml'iling sheets at ditlereut relative positions with respect to each other, so that the writing may be reproduced on several sheets and on the proper lines on ditlerent sheets, there is provided a collating frame or paper-carrier 26, which normally extends around the platen 1 between the platen and the pressure feed-rolls l0 and '11. This frame is made of a sheet of dlexible material, which has attached thereto a pair of collating strips 27, arranged to extend around the platen at opposite ends thereof. These collating strips 2? are providcil with 'laper-holding means or collating studs upon which. the Workcollating frame 26.

have perforations on either side margin, or;

sheets 27 may be impaled to adjust them relatively to each other and relatively to the T he work-sheets may if wide enough to stretch across the frame, on both side margins, so that they can be placed over the studs 28. It will he noted that the strips 27 extend around the platen 1 in such a manner that the studs face to the front, and are located at that end of the strip 27 which extends upwardly from the front of the platen 1. This enables the work-sheets 27 to be impaled on the studs 28 facing front with their leading edges uppermost.

Normally, a driver in the form of a spring 29 tends to hold or withdraw the collating frame 26 to its starting position shown in Figs. 4 and 5. This spring 29 is connected to levers 30 and 31 forming part of an expanding device having a lazy tongs motion. This expanding device is slidingly pivoted at 33 to a guiding and supporting plate 34, which extends upwardly from the rear of the platen frame 3. Floating pivots 35 of the expanding device 32 are yielda stud 40 ex-'-Q5 rear end of the collating frame 26 is caught onto the cross-bar 41 by means of a pair of hooks 42provided on the cross-bar 41, and

extending through openings 43 provided on the tail end of the collating frame 26. spring 29, through the lazy tongs 32 and the cross-bars 39 and 41, normally exerts a pull on the tail end of the collating frame 26, so as. to hold the latter taut.

The action of the spring 29 is opposed-by a second spring 43*, which tends to extend a second expanding device 44 in a manner similar to the first expanding device 32. The second expanding device 44 is'eonnected to the leading edge of the collating frame 26. This connection includes a cross-bar 45, located in back of a supporting and guiding plate 46, extending up from the front side of the platen l'and supported by the platen fran'ie 3. The guiding plate 46 is provided with a slot 47, through which extends the moving pivots of the expanding device 44. The cross-bar 45 is also connected to this slot 47- through a front cross-bar 48 by means of a pin 49. The cross-bar 48 is located in front of the plate 46, and is provided with The hooks 50 to extend through openings v51 in the leading edge of the collating frame 26, and thereby support the collating frame. Inasmuch asthe first spring-actuated e! panding device draws on the tail end of the collating frame 26, and the second springactuated expanding device draws on the accuses Leading edge of the collating frame 26, the frame will be held tight on the platen 1, and the free ends thereof, which extend from the platen, will be held taut. For the purpose of maintaining the col' lating frame always in the same relative line-space positions with respect to the platen, or in other words to prevent slippage, as the collating frame moves back and 0 forth with the rotation of the platen, a pinand-sprocket arrangement is provided. This includes pins 52 located on both ends of the platen 1 in a circular series, so as to form sprocket wheels, which engage in perforations 53 provided on both sides of the collating frame 26. In this way, the position of the collating frame will be justified and the line-space intervals always maintained in corresponding relation with respect to the platen 1.

After the sheets are assembled on the collating frame the platen is revolved backwardly or reversely to carry them around to their starting position To enable this reversal to be easily done, the pressure feedrolls 10 and 1.1 are released, and the detent 7 is withdrawn. from engagement with the line-space wheel 6 by an operation of either the finger-piece 14 or the hand-lever 21. The spring or driver 29 now becomes effective to feed the collating frame backwardly to introduce the work-sheets into the machine. The releasing mechanism is automatically tripped When the collating frame reaches a position corresponding to the proper placement of the work-sheets on the platen after they have been assembled. This is done automatically by an adjustable stop or trip 54 provided on the collating 40 frame 26. The trip 54'may be secured in any one of a number of holes 55, so as tovary the instant of its action, and thus make its action correspond with the particular requirements of the Work being collated. The

trip 54 travels around rearwardly with the collating frame 26 until it comes into enagement with an arm 56 on a bell crank 57. Then the trip 54 will rock the bell crank 57, so as to force an arm '58 on the bell crank against one of the arms of the hand-lever 21. The hand-lever 21 is rocked from the position shown in Fig. 3 to the position shown in Fig. 4, thereby restoring the detent '7 and the presspre feed- rolls 10 and 11.

55 After this latter action has taken place, the collating frame is positively arrested by the stop 54 cooperating with the arm 56.

When a new piece ofwork is to be done, I)

the parts are adjusted to the position shown 6%) in Figs. land 2, to enable the work-sheets to be easily collated. The work-sheets 27,

' with. the interleaved carbon sheets, are then collated by being impaled on the studs 28 in the various relative positions desired, so as. as to have the desired lines thereon in regisof the platen 1, so

ter with each other, although these lines may not be at the same relative positions on the several sheets. After the sheets have been assembled or collated, the release key 21 is actuated, thus rendering the spring 29 effective to reversely rotate the platen, and it will carry the collated work-sheets, bottom edge first, down around the platen until the trip 54 comes into engagement with the arm 56 and bell crank 57. Then the trip 54 will first unlock the releasing mechanism, enabling the detent 7 and the pressure feedrolls 10 and 11 to return to their active positions. The trip 54 thus limits the return movement of the collating frame 26 by causing the detent to arrest the reverse rotation that the initial position of the collated work-sheets for the first line of writing is automatically determined. This may be chan ed as desired to suit the charactor of wor by adjusting the trip 54 in any one of the openings 55. When so positioned, the work may be written line by line until completed, the frame 26 traveling in synchronism with the platen 1, inasmuch as it is positively geared thereto by means of the pin-and-sprocket arrangement 52, 53. The rear support 34 will keep any worksheets from dropping off the studs 28, especially any that extend only part way across the platen. When the work is completed, it can be detached from the studs 28 and a new set of sheets collated or assembled on the collating frame 26. During the back and forth movement of the frame 26, the springs are maintained taut and the work sheets held smooth in all positions of the latter.

The collating frame may be readily detached from the machine and replaced by another having its rows of collating studs spaced differently apart, as it may sometimes be desired to collate sheets with dif; ferent distances between rows of perforations or collating holes. The collating frame is detachably be conveniently replaced since it becomes worn by the frequent hammering of the type-bars, if it extends across theplaten and serves as a backing for the work-sheets.
