To all whom z't may concer:

Be] it known that I, JEssE A. B. SMITH, a

citizen of the United States, residing in,

Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Type- VVriting Machines, of which the following is a specification.

This invention relates to an improvement in typewriting machines, and more particularly to an attachment of the fan-fold type, but in which the work-sheets are on separate strips, and is an improvement on my application No. 165,055,filed April 28, 1917, and iatent to Lester A. Wernery and Jesse A. i3. Smith, No. 1,132,055, dated March 16, 1915.

The present improvement is applied to an lattachment for typewriting machines whereby a number of copies of' the same piece of work can be simultaneously Written, and a large number of pieces of work produced successively by the interleaving of carbon sheets with continuous strips or webs of work-sheets. The carbon sheets are repeatedly used and the work-sheet strips spaced relatively to them for each new piece of work.

To effect the spacing between the worksheet strips and the carbon sheets, the platen is swung up out of its normal typewriting position so as to straighten out the bend in the pack of interleaved carbon and worksheets. In this way, the friction is reduced so that the work-sheet can be shifted relatively to the carbon sheets, and vice versa.

Where the worksheet strips are separate, as in the present invention, there is attendency of the sheets to creep relatively to one another, due to the folding and unfolding around the platen. Provision is therefore inade in the `present invention for enabling the sheets, when they are spaced for each new piece of tyoewritten work, to. be justi` fied or re-registered relatively tri-.one another, thereby preventing the creeping from being cumulative.

For this purpose, there are provided two or more studs which cooperate with perforations provided in the side margins of the These perforations mayL be used for assemblin the completed s eets later in loose-leaf Eooks, if desired. The studs are normally retired 'lor moved to a non-projecting ppsition, so that when the sheets are fed around the platen for typewriting the studs will not interfere with the line-feed movements of the paper. When, however, the platen is raised to a/fposition to take out the bend or Warp in the pack of assembled sheets, then .'the studs a automatically projected to gaging positions, so that the work-sheets can be strung thereon. Then, when the platen is returned to its noi'- mal position, the studs are automatically receded to a non obstructing position, the

sheets being then under the control of the' usual feed rolls. The automatic projection and recession of the collating or aging studs are preferably controlled by te swinging ofthe platen from a normal typewriting ,position to a collating position and back again.

Other features and advantages will hereinafter appear.

Referring to the drawings,

Figure 1 is a perspective View, partly broken away, to show the underlying structure, and illustratin the platen in its normal typewriting position, with the pack of assembled work and carbon sheets wra ped around the same, as shown in dash-an -dot lines.

Fig. 2 is a side` view in elevation, with parts broken away to show the underlying structure, and the platen in the Same posisheets withdrawn rearwardly from the platen,

enabling the forward spacing of the worksheets relatively to the carbon sheets. The

gaging or registering studs are shown in their projectin positions, which are coincident with the e evated position of the platen.

Referring more particularlyv to the se arate parts of the device, `1 indicates t e platen, which is secured'to a platen axle 2, mounted on an auxiliary frame. 3, within the usual platen frame 4. The auxiliary frame 3 has a pivotal mounting by means of a rod 5 on the platen frame 4, so that it can be swung from the position of Figs. 1 and 2 to the position of'xFig. 8. This is for the purpose of relative rif-adjustment of the work-sheets and carbon sheets in a manner more fully described hereinafter.

The usual lever (3 is provided for effecting line-hy-line feeding movements of the platen 1. The line-space lever 6 is provided with an arm 7, which engages theusual slide 8, havin an adjustable line-space dog, (not showiil, which engages at the proper time a ratchet wheel 9, secured to an axle 10,oarry ing the usual knob 1l, whereby the platen is ordinarily spaced back or forth several lines at atime.

ln order to allow for the movement be-r tween the axle 10 and the axle. 2, which are in al'inement with each other, but separate, a special gearing is provided in said patent. There is secured onv the axle 10 a gear 12, which take-.s all the movements of the axle 10, due to the line-spaoe lever 6 and the knob l1. The geur 12 meshes with a broad pinion I3, which also overlaps a gear 14 of the same diameter as the gear 12, but seem-ed .to the axle In this Way, the movements of the linespaee lever (i and (he knob l1 are transmitted to the platen I. The pinion 13 is concentric with therod 5, about which the platen .swings as a center, so that there is Aio break in the driving train when the platen is moved between typewriting and re-registering positions.

To swing'the platen 1, there is provlded u hand-crank 16, secured to the swinging iframe 3. rThe swinging frame end the handrrank 16 are normally held in a types` writing position of the platen'hy a latch 17, which engages a pin 18, provided on the hand-crank 16.

The morir-sheets, which, in the present inventirm, are preferably in separate strips, coming from separate rolls or from a` loose parli, v(not shown). extend 'from a point somewhat in the reni' of the platen. The worksheets, indicated by the reference numeral 19, extend over a guide 'frame 20, which is secured to the platen frame 4, so as to travel with the carriage in a letterspacingdireetion. This frame 20, is supported at its rear end. by e roller 2l., riding on. a. rail 22, carried by a pair of brackets Q3, mounted on the frame of the typewriting;V machine or other suitable support.

The carbon Sheetgindicated at 24, of which there are two shown, are supported so as to he interleaved between the worksheets 19. For `this purpose, there ispro vided a traveling table 25, having a movement toward the platen to keep pace with` the advance of the sheets around the platen. The table .25 is provided with rollers or wheels 26, which travel in tracks 27, provided by the side rails of the frame 20. Ex-

tending alternately, inwardly fromy the frameQO from the sides of the traveling table 25, are supporting arms 28 and 29 for the carbon sheets 9A. The inner ends of these arms are free, so that the looped ends of the carbon sheets 24 may be slipped onto the arms 28 und 29. Il more worksheets than three are used, more carhons may lie-670 1, Where the usual typ-.liars 36 strike the i platen. From this point, the assembled work and carbon sheets pass up onto a registering taille or board Iii". which serves also as :t guide. The registering table may he provided at its right-hond side` with e slidable side gage wij. which may be adjusted lengthwise of the i. istering table for worksheets of different Widths.

At theleft-hand side of the registering table 37, there are provided two or more openings 39, corresponding to perforations 40,provided in the work-sheet strips 19. These perforations may be used for assembling the separated pieces of work later in loodeaf hooks, if desired. They are also used forkadjusting the several strips rela tively to eachother from time to time, so that the aline-ment of `the different sheets with each other muy be aeeurate. This is necessary in eases where the work-sheet strips 19 eaeh are. com osed of continuous repetitions of forms ofpeome sort` or other, and it is desired that certain portions of each form aline prorly with each other,

so that metter may in he proper place. The registeringie le B' is=oxzended at 41 to allow foruone of the openingsBQ and other mechanikmto be now described.` The openings 39.`n the registering? trahie 37 are for the purpose, of permitting et ds 43 to be shifted rom e normal, rede position, shown in Figs. 1: and Q, to a. proi im )ected position, shown in- Fig. 3. 'Iheistuds 43 are mountedon a block 44, Which,at.Fi

2, is located in bank of the registeringteb e 37;"-.a.nd the latter being seen at this figure in `its normal position. The block 44 is shifted by a slide 45, The slide 45 hais pinand-slot connections 46, with supporting lugs provided on the` back of the register,

ing table 37. A spring=`47 tends to draw the slide 45 from the Fig. f2 position to the'Fig. l 3 position. This' tendency is opposed by a. rod 4S, en aging a ca'm 49, provided on the slide. he/rod 4851s, secured to', the fixed portion of the plalniframe 4.
