TYPE-WRITING- MACHINE.

Application filed July 14, 1917.

To all whom it may concern:

of Louisiana, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to an improvement in typewriting machines, and more especially to an attachment whereb several sheets may be collated or assembled in proper relative positions for placing on the platen of the typewriter.

In the present embodiment of the improvement, provision is made for assembling or collating the work-sheets at the rear of the laten, and in such a position that they laten from the rear. In general, this mechanism consists of a pair of bands, driven in the manner of a chain= and-sprocket from the platen, so as to move around therewith. These bands are provided with collatin studs at suitable intervals, so that they wi 1 hold the sheets in their relatively assembled positions and carry them to and around the platen. Springactuated lazy tongs normally tend to hold the bands, as a unit, withdrawn from the platenin an assembling position, but these lazy tongs yield to enable the bands and sheets thereon to be advanced to and fed around the platen. For deliverin the sheets to the platen when once assemb ed on the bands, :1 cross-piece uniting the bands is bent over on itself to form a handle, by means of whichthe bands and work-sheets as a whole can be drawn around the platen. Before this is done, the pressure feed rolls for the laten are released by a finger-piece which a so releases the detent for the line-space wheel to ermit the free movement of the platen. l vhen the initial line of writing, determined on the work-sheets, reaches the printing position, a settable stud, carried by one of the bands, restores the finger-piece and both the pressure-feed rolls and the detent operated thereby. "This creates considerable resistance which in turn warns the operator that the bands have been moved a sufiicient amount.

A spring is provided, whereby, after the typewriting operation has been completed, t e release of the line-space detent permits Specification of Letters Patent.

the collating board and sheets to be retracted to normal position, where a new collating operation ma take lace.

The drive ands or the collating device may be made of celluloid or other suitable flexible. springy material, which may, if desired, be transparent. The collating studs may be made of metal and mounted upon a strip of flexible metal which is suitably attached to the celluloid drive bands.

Other features and advantages will hereinafter appear.

In the-accompanying drawings,

Figure 1 is a perspective view, viewed from the front, showing the pressure feed rolls and detent released, and alsothe bands in their withdrawn position, ready for the assembling or collating of sheets, and the delivering of them, after assembled, to the platen.

Fig. 2 is a front view in elevation, with parts broken away to show the underlying structure, and showing the mechanism after the bands have been drawn around the platen, with the Collated or assembled worksheets in position for the initial line of Writing.

Fig. 3 is a vertical section, taken from the left-hand end of the platen, and shows the parts in the position corresponding to Fig. 1, with the collating bands withdrawn from the platen, ready for the assembling of the sheets.

Fig. 4 is a vertical section, taken from front to rear, midway of the platen, and showing the parts in the position corresponding to Fig. 2.

he platen 1 is mounted on an axle 2, which, in turn, is mounted on a platen frame 3, supported by a carriage 4. The carriage 4-. travels in the usual way, common to Underwood typewriters, on rails or guides 5. For guiding work-sheets of v'arious character to the platen, the platen frame 3 is provided with an apron 6. A shield 7 forms an extension of the apron 6 and deflects the work-sheets around the platen 1.

To assist the platen 1 in feeding worksheets positioned thereon, there are provided the usual pressure feed rolls 8 and 9, which are mounted, for movement toward and from the platen, on frames 10 and 11. These frames are provided with oppositely-projecting arms 12 and 13, whereby the pressure feed rolls 8 and 9 may be manipulated toward and from the platen. Normally, the rolls 8 and 9 are held in intimate contact with the platen h springs (not shown). To disengage the ro ls from the platen, there is provided a release finger-piece 14 (Figs. 1 and 4), which, when. depressed, draws up on a link 15 to rock a shaft 16. This shaft 16 is provided on the 0 posite sides thereof with cut-out portions 1 and 18, into which extend, respectively, the arms 12 and 13. When the shaft 16 is rocked at the depression of the finger-piece 14, these arms are forced out of the notches, so as to s9read them apart, against the tension 0 the springs, thereby spreading the rolls 8 and 9 from each other and from the platen 1. This is the usual pressure feed roll mechanism.

The pressure feed roll mechanism may be operated from another point for the purpose of releasing the rolls, to permit the easy 11]- sertion of collated or assembled work-sheets. For this purpose, there is provided a keylever 19, Fig. 1, pivoted at 20, and carrying at its rear end a rod 21. This rod, on one side of the lever 19, is provided with a link 22, which, when the key-lever 19 is de pressed, draws up on a disconnector 23, which disengages a detent 24 for the usual line-space wheel 25. This detent, normally, yieldingly holds the line-space wheel 25 and the platen against accidental rotation. The disconnector 23 is connected to operate the rock-shaft 16 by means of a link 26 and a sleeve 27, the latter being secured by a setscrew 28 to the rock shaft 16. In this way, the key-lever 19 will simultaneously throw oif the detent 24 and release the pressure feed rolls 8 and 9, thereby enabling the platen to rotate freely. A notch 23* in the disconnector enables the same to be held in disconnecting position by the spring detent 24.

For assembling or collating a plurality of work-sheets to lace them on the platen in proper order, t ere is wrap ed around the platen 1 a pair of bands 29. These bands 29 may be bipartite and each include va perforated drive strip 30 to engage sprocket teeth 31, provided on the ends of the platen 1. This enables the bands and the platen to travel in unison, always maintaining the samerelative position. The bands 29 are preferably made of celluloid or other suit able flexible, yet springy, material. A flexiblemetal str p 32, Secured to each of the celluloid strips is provided with collating studs 33, arranged at suitable intervals. The parts 30, 36 and 37 may be cut out of one sheet of celluloid and the metal strips 32 secured thereto by clips stamped out of the body portion of the strips,30,.as at 60. The collating strips 32 are arranged to travel with the drive strips 30, around the platen 1, the platen 1 being provided with cut-out channels 31 and 95, Fig. 2, to permit this movement around the platen without interference.

The drive strips 30 and the collating strips 32 are united by a cross-piece 36 at their upper ends, and by a looped cross-piece 37 at their lower ends, as seen in Fig. 1. The strips 30 and 32 and the cross-pieces 36 and 37 form a flexible collating frame. The cross-piece 37 is looped for the purpose of enabling the o erative to grasp the same and draw the flexi le collatingframe as a whole around the platen, and also so as to be easily deflected by the studs 33 during a normal t 'pewriting operation.

The co lating frame is detachably connected to a cross-bar 38 by means of books 39, which extend through openings 40, provided in the collating frame. The cross-bar 38 is located in front of a plate 41, mounted on the platen frame 3 and extending up from a point somewhat in the rear of the platen. This plate is provided with a vertically-extending slot 42, through which passes a pin 43, connecting the front cross-bar 38 with a rear cross-bar 44, located in back of the plate 41.

The cross-bar at has connected thereto, by means of pin-and-slot connections 45 and 4.6, a pair of lazy tongs 47. The lazy tongs 47 are provided with headed pins 48 at two of their points of intersection, which engage in the slot 42, so as to guide the movements of the lazy tongs. The lazy tongs are fixedly pivoted at 19 on the plate 41, and the arms 50 and 51, which extend below this pivot, are joined by a spring 52. Thus, the spring 52, through the lazy tongs and the bars 44 and 38, normally holds or tends to draw the flexible collating frame, including the bands 29, in their up ermost position, which position correspon s to the position they occupy after having been withdrawn. rearwar 1y from the platen 1 After the sheets are assembled on the collating studs 33, one upon the other in proper relation to commence writing, the collating frame is drawn around to the position of Fig. 4, to bring the initial line of writing of the Work-sheets to the printing point of the platen, indicated at 53. To determine this position automatically, there is provided a trip or stop 54, which may be located in any one of a plurality of aging holes 55, provided on one of the bamfis lating frame. The position of the trip 54 determines how soon the limit of positioning movement of the collating frame, with the sheets thereon, shall be reached. This trip,

as the collating frame travels around the.

platen, comes into engagement with a latch or stop 56, provide on an extension or sleeve 57 on the rod 21, mounted on the release-key-lever 19. When the trip ,54 engages the latch 56', it rocks the key-lever 19 29 of the GOT-w and restores the detent 24 and,the press r feed rolls 8 and 9 to their engaging position with the line-s ace wheel and the platen, respectively. he latch 56, as Will be. seen by reference to Fig- 2, is normally held in its outer position by a-.spr-ing 58. When engaged by thefitrip 5,4,the latch 56 is. moved so as to permitthe tripbl, after the work-sheets have been'properly placed on the platen, to travel farther during a normal typewriting operation. This latch 56 is beveled on its under surface at'59, so that it will automatically snapback, permitting the trip 54m pass :when the spring 52 returns the collating frame by withdrawing it reversely from theplaten.

The utilityofthe devicewill be readily understood when taken in connection with the abovedescription. Two ormore Worksheets, having perforations in either one or both side edges, are placed on the collating studs 33 wlren-the collatingframe is-.withdrawn to its Figs. 1 and 3 positions. The sheets may be set relatively toeach other, so as to bring lines at different points in their length, as to the individual sheets. into coincidence with each other. Thesheets are separated by carbon sheets, so thatitheimatter Written on the -front sheet, when at the platen, which willbe the rearsheet, in assembling, will take onthe under sheets.

Atl ter the sheets have been assembled or collated in this manner, theyare ready to be positioned on the platen Without removal from the collatingframe. This is done simply by catching hold of the looped crosspiece 37 and drawing on the same. after, however, the pressure feed rolls 8 and 9 and the line-space wheel detent 24 havebeen released by a depression of the key-lever 19 to the Figs. land 3 positions. On this'release of the detent and feed rolls, the platen will rotate easily, enablin the collating frame to be moved from t e positions of Figs. 1 and 3 tot-he positions of Figs. Qand 4, carrying with it the assembled or collated sheets.

\Vhenthe initial line of Writing, .:predetermined upomreaches the printing point :53 of the platen. then the trip Willengage the latch 56.:t0 rock the keydever 19,.and throw on ,both theidetent 24 and the ,pressure feed rolls 8 and 9. The assembled sheets are then in aposition for-.typewriting. The latch 56 can be withdrawn against the tension :of its spring, so as to permit the-trip 54-to= ass, enabling the platen, the worksheets-.2111 the collating frame to be advanced, line by line, in a normal typewrit-ing operation.

When the piece of work is completed,.the detent 24 and the pressure feed rolls 8 and acan again-be released b awdepressionof .itheekey lever 19,50 that t e s r ng52. may act to withdraw the collating .rame.and the he iaa rn e ther bp reamard y t e the platen.

.pair .of guide rollers 61.

Then the completed piece of work eanhe removed from thecollatin frame. and ires'hsheets assembled thereon ortauew piece of Work, and the operation repeated as before.

It.will be noted, because of the fact that the studs 33 are able to pass around'theplaten while facing in toward the axle of the same, that it is possible to collate .or assemble the sheets and insert thermal. the rear of the platen while still on the collating frame. This makesthe action correspond to the normal insertion ofsheets on the type- Writer platen, andat the same time. prevents their getting'out of register.

It will be seen'that when passing around the laten, the side margins of the sheets are con ned between the platen and collating hands. This holds the sheets firmly onthe platen in printing position.

The spring 52, connected to the lazy tongs. is arranged so as to withdraw the collating). bands to normal collating position after the typewriting has been completed. To permit this action, the line-space detent is moved away from the line-space wheel. In a normal typewriting operation, the spring does not return the collating hand (although there is a tendency to do so). because ofthe engagementof the line-space detent with the line-space wheel, which affords considerable resistance to the turning of the platen.

IThe collating bands are held close to the platen above the writing line, bynieans of a 7 There is one of theseguide rollers providedat each side of the machine and overlying the collating bands.
