TYPnwnrrIne MACHINE Application filed Augus't 11, 1919. Serial'No. 316,544.

To all whom it may concern Be it known that 1, Jesse A. B. Sana, a citizen of the United States, residing in Stamford, inthe county of Fairfield and State 01 Connecticut, have invented certain new and useful Improvementsin Typewriting Machines, of which the following is a specification.

This invention relates to typewriting marchines, and is herein disclosed as applied to the socalled Underwood fan-fold billing machine, one form oi whichis disclosed in the patent to Vferner &. Smith, No. 1,132,055,dated March 16, 1915. l

' The Underwood tan-fold billing machines are usually made oft substantial width in order to accommodate comparatively wide forms, but it is sometimes desired to use such machines either continuously, or for more or less long periods of time, upon work requir ing narrow Webs. According to the'present invention, a machine adapted to use a com paratively wide web may be readily transtormed into a machine adapted to use two webs which may be kept-in, the ma chine side by side, and which may be typed upon alter-- nately, or one of which may be used for con siderable periods of time while the other is left idle.

The present invention has especial. utility for typing alternately upon complementary work-sheets arranged in continuous or web form, and these wees, whichpass through the machine side by side',-that is, edge to edge, may or may not be fan-folded webs By complementary work-sheets it is meant that the successi qe sheets making up one of the webs bear a complementary relation to the successive sheets making up the other web. That is to say, the worksheets in one web bear a certain definite relation to the work-sheets in the other web, this relation being dependent upon the nature of the "forms which may havebeen printed upon the work-sheets, or "it may depend upon the character of the cut fies which are to be typed upon complementary work sheets, or: it may depend upon both of these factors. For example, in using a continuous billing type- 7 writing machine to write on the successive sheets of a web, and to write also upon other successive web sheets which are comple' mentary to the first,it is necessary to alter-' nate the writing on one sheet with that on; the other. With the ordinary tan-fold or;

continuous'billing' type of machine, it'would be'necessaryto remove one of thewebs from the machine together withlitscarbon -holdingcarriage, and insert the other web in the machine, at the same time placing in position thereon its carbon-holding carriage, thereby. causing waste of time and liability of error.

The present invention provides for guid v ing and laterallygaging a plurality, such as a pair, of webs, or web-sets, side'by side to and" around a unitary or sii'igle-section platen.

In order to enablethe utilizationof 'nar-' row webs without more extensively modiiying the structure of theme'chan'ism, the usualbars to which the carbon sheets are clipped may be replaced by bars comprising slitting members adapted to slit the fan-fold webs at theirlfo'lds, where they are usually per'-' tor'ated', sothat the Webs are slit onreachingthe carbon clip barsor just before reaching themfthus permitting each clip-bar in extend'across beyong the folds of one fan-fold web and hold a'carbon for one ormore other tenfold webs. Inasmuch as the carbon clip bars in the usual fan-fold machine are inter changeable 'to a large degree, the usual bars may be readily replaced by the bars modified. according to the present inventiom'without the need of even calling in a repair man.

In order to guide the webs, the usual edge gages upon the carbon carriage may be supplemented by additional edge gages, so that each fan-fold'web, or other form of web set,'is 'gaged at each edge thereof. The usual rear bar over which the webs are drawn may, it desired, also include edge gages tog-age the various webs. Theordinary leading edge gage which extends abovethe swinging paper table in the usual fan fold machines may be replaced by a separate end gage for each fan-fold web,'said end gages advantageously being allsupported; from a single bar, which is adapted to'be attached where the usual end gage is attached.

Other features and advantages will hereinafter appear. i

In the accompanying drawings, Figure v l is" aifragmentary perspective view, largely diagrammatic, .ofan Under wood fan-fold billing machine, showing the present invention'applied thereto.

Figure Zisa plan view of a'carbon clip bar, showing the carbons clipped thereto and the severing devices attached thereto Figure 3-is a view similar to Figure 2, but showing an additional clip bar, and dia grammatically showing how the webs are slit. I v I Figure-4 is a sectional end view of the parts and webs seen in Figure 3.

Figure 5 is a perspective view of aslitting to provide for straightening out and easing the webs, whereby the webs may be drawn forward and gaged at their leading edges, as heretofore. 1n orderto rotate the platen, there is provided the usual line-space handle 14, which is adapted to rotate the usual line-space wheel 15, which is fasttO a pinion 16 and meshes with a pinion 17 upon the shaft 12, which, in turn, meshes with a pinion 18 fast to the axle of the platen 10, with the result that every time the line-space handle is actuated to turn the wheel 15 it turns the platen 10. I The carriage 13 is mounted upon rails cluding the rail 19, and is fed along in the usual manner whenever any type-bar 2O rises to print upon a work-sheet passed around' the platen. The fan-fold billing machine also usually includes a rear extension 21 of the carriage having rails 22 and 23, upon which a carbon carriage 24 is adapted to be reciprocated by a handle 25. The extension 21 also includes a cross-bar 26 connecting the rails 22 and 23, which support the cross-bar 27 over which the initially fan-folded complemental webs 28 and 29 are adapted to be drawn past the carbon carriage and under the platen and up over the front paper table 30. For supporting the rear end of the extension 21, there may be provided a rail 31 fast upon an extension 32 extending rearwardly from the typewriter carriage. The carbon carriage 24 includes the usual foundations 33 at each side, provided with the usual openings 34 into which pins 35 upon carbonpaper clip-bars 36 are adapted to fit interchangeably.

According to the present invention, each carbon clip-bar 36 may be adapted to slit one fold of each web. Since there are shown two webs 28 and 29, each bar is venient to guide theedge of the other web.

In addition to the slitting devices 37 and 38, each carbon clip bar is provided with a clip 39 adapted to hold a carbon sheet for each sheet of web upon which a carbon copy is desired, and for the purposes of the present disclosure each clip bar comprises two of the clips 39, one pivoted on the usual pin 40, and the other on a rivet 40, so that they may be swung rearwardly away from their clip bar to permit the carbon sheets 41 to be folded over the end of the clip bar and then held to the bar by swinging the clip 39 gainst them. The fiat rivet 40 permits the adjacent web to slip smoothly over it. Thus it will be clearly seen, as diagrammatically shown in Figure 4, that two fan-fold webs having the same number of folds maybe slit by the carbon clip bars which extend across them. The slitting devices have been found to be very effective if made in the form shown, in Figure 5, in which each slitting device is a wire slotted to, slide over the clip bar 36 and to be held theretoas by soldering, the wire also having a turned-over end 42 to prevent its end, by any accident, from marring the surface of the web sheet. An angle of approximately 60 has been found to be a very eflicient angle for the slitting device.

For guiding the . complemental webs 28 and 29 up to the carbon carriage, each foundation 33 is provided with the usual opening 43, into which a thumb-screw 44 is adapted to be screwed, thus holding in place not only the usual edge gage 45, but also a supplemental edge gage 46 for the free edge of the-web, there being on the two foundations taken together enough edge gages to have a separate edge gage for each edge of each web. The edge gages 46 may comprise right-angle extensions 47, which are curved down and then horizontally to- 'clear the rearmost clip bar 36, and then bent upwardly to form an edge gage 50 against which the edge of the web is adapted to bear. When a form or other suitable stretch of web has been typed, the usual handle 51 is pushed rearwardly to release the swing frame 11, and then the swing frame is swung forward in the usual manner, and the web which has been typed is drawn forward and gaged against the appropriate one of the adjustable end gages 52, of which there is one onceach of the extensions or supports 53, extending above the paper table 30. If the table 30 is-p-rovided with a roll 54, as it sometimes is,,at the top, the rollis cut away at 55 to permit the support 53 to lie nearly at the surface of the table. The two supports '53 may spring from a single bar 56, which is adapted to be held by the usual thumb masses After the web has been gaged, the carbon carriage is pushed rearwardly by the handl 25 until it strikes the usual stop 58.

The operation of handling either web is, in general, the same as in the ordinary fanfold billing machine. In the machine of the present invention, the typing ordinarilyis done alternately upon the complementary work-sheets making up the two webs. Should one of the webs not be used, the one not typed for the time being may be allowed to take care of itself, or its end may hang idly over the bar 27. To further guide the webs at the bar 27, the bar, which is usually removable, is provided with the usual screw 59 to enable a suitable number of stops or side gages 60 to be adjusted thereon, so that there is a side gage at the bar 27 for each side of each of the webs.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I claim:
