TYPEWRITING acrame.

Application filed January This invention relates to 'typewriting machines of the variety set forth in the patent to Wernery & Smith, No. 1,132,055,- dated March 16, 1915, in which work-sheets or printed forms may be fed to the machine in succession as elements of a fan-fold .web, which may be led into the machine anl passed downwardly, forwardly, and up around the revoluble platen, and in which carbons may be interleaved between the elements of the fan-fold web or between they loose plies of other work-webs. As disclosed in said patent, the platen is displaceable to permit the webs to be straightened out, so that the carbons may be readily shift, ed back along the plies of-web to unused portions'thereof. V i

In using this'machine to turn out a va; riety of work, it is sometlmes desired to. have assembled, ready for immediate use, a

plurality offan-fold webs with a plurality of carbon-carriers, so that typewriting can be done upon either set of webs, at will,

and, for this purpose, it hasbeen the prac- 2 tice to provide -carbon-carr1ers which are readily detachable from the'machine, so that,

when it is desired to stop typing on one set of around the platen of the machine in fan- 40 fold form.-

Another feature is I thatthe means provided are in the nature of an attachment to the Underwood standard typewriting ma- .chine of the ,variety hereinbeforespecified. According to the present invention, a widecarriage machine'may be readily adapted, with little or no alteration thereof, to use'two webs which may be kept in themachine side by side, and which maybe typed upon alteror one of which may be used while the ot er is left idle.

In one form of this invention two paral-- lel work-webs having a plurality of plies are inserted in the machine by interleaving the t5 li f th eb with carbon-sheets fastened '12, 1925. Serial No. 1,755.

to cooperating carbon-paper clips. The leading edges; of the two webs are fed over a rear table, then down around the platen to engage with cooperating feed-rolls and up in front of the platen over a front table; One of the work-webs may then be typed upon and line-spaced step by step. The platen is then swung forwardly in the ordinary way to straighten out the webs, and to' draw up the active "web to its corresponding leading-edge gage, of which the are two, .one for'each work-web, so that the'carbonsheets. interleaving thetyped or active web may be backed up into a new portion covering a fresh section of said web. In order to move the carbon-sheets rearwardly, -it will be necessary to hold the leading edge of the typed or active web against thegage, otherwise the friction of the carbon-sheets against the leaves of the web would move the web along to the rear when the carbon-carriage and the carbon-sheets are moved backwa-rdly.

It will be noted that both the idle and the active webs are simultaneously line-spaced while typing upon the active web whenthe typing upon the active web is completed, the platen isdisplaced, and the leading edge of the" active web is drawn up to itscorrespond ing gage. The scarbon-carriage is then moved rearwardly to position the carbons in a fresh section of the active web while the idle web is moved rearwardly with the carbons. due tothe friction of the paper-clips andcarbon-sheets interleaving the plies of the web. It will be noted also that while the carbons are retracted the active web is held with one hand against the gage while the idle-web is left free to follow the car- ,bons.

When the platen is loweredto its normal or effective position, the leading edgeiof the idle web has a tendency to shift out of place,

or, in other words, to shift from a position between the-knife and platen, and above the knife as.shown in Figure 10, to a position considerably below the knife, and, in order to control the web while the platen is moved, there is provided. aclamp extending the full width of the front table to effectively hold thefiwebs between the table and the clamp. A. latch is also provided to lock the clamp while the platen is swung.

In operation, the clamp isliftedjby means of' a handle and the latch snaps and holds the clamp in place while the platen is low.-

ered. Previous to severing the active web, however, the clamp must be restored to its ineflective position, so that the web may be torn off against the knife.

Other features and advantages will hereinafter appear.

In the Underwood fan-fold typewriting machine, a platen 10 is journaled in a swing frame which includes end plates 11 and 12, journaled'to a front shaft 13, extemding across the platen-carria e, so that the platen ,may be swung forwar ly in line with the work-webon the fan fold table and clear of the feed-rolls 14 'and 15, which usually cooperate with the platen for feeding the work-web in line-space direction. The platernis shown geared to -the line-space mechanism, which includes a line-space lever 16, by means of pinions 17 fast on the axle 18 of the platen, said pinions meshing with idlers 19 on the front shaft 13, which idlers, in turn, mesh with pinions 20 fast on the shafts 21 which carry finger-wheels 22 for operating the platen, and are journaled in platen-frames 23, f

platen and the including the rail 24 and. is fed along in v the usual manner whenever any type-bar 25 rises to print upon a work-sheet passed around the platen. The fan-fold machine also usually includes a rear extension of the carriage having rails 27 and 23, upon which a carbon-carriage 30 is adapted to be reciprocated by a handle 31. Said rear extension also includes a cross-bar 29 connecting the rails 27 and 28, which support the cross-bar 33 over which the initially fanfolded complemental webs 34 and 35 are drawn past the carbon-carriage and under the platen and up over the front table 40. For supporting the rear extension there may be provided wheels 26 operatively mounted upon a rail 39 fast upon a rearwardly-extending bracket. 32 which forms an integral part of the main fraine 36. Upon the carriage 30 there are provided the usual plates 37 for supporting the wheels 38 which operatively guide the carriage 30 on the rails 27 and 28.

When the work-webs 34 and 35 are initially fed to the machine, they are'passed over the rear cross-bar 33, between paperguides 41 and 98, and between carbonfingercarrying frames 86 on the carbon-carriage 30, the webs being interleaved with carbonshe-ets fastened in the usual manner to carbon-fingers 43. lVith the leading edges of each web in alignment, the'webs are inserted between the knife andthe platen,jwhen the is returned to its normal or effective position, the leadingedges "will be above the knife. The platen is then reversely rotated to simultaneously back-feed both webs until the leading edges thereof coincide with the cutting edge of the knife, when typing upon either web can take place.

' Supporting guides 45 and 47 aremountedupon the front table 40 by means of thumbscrews 97, and slidably and adjustably mounted upon the guides are leading- edgegages 44 and 46 respectively, one for each web.

While the necessary data is being typed upon one of the webs, 34 for example, and

line-spaced, it will be understood that the other or inactive web 35 will also be linespaced.

' The platen isthen' swung forwardly to straighten. out the webs, by releasing the latch 48, to a position as shown, in Figure 8 so that the carbon-sheets interleaving the active web may be backed up into a fresh section of the web. Since it is customary to write but a few lines on each web, it very seldom occurs that the leadinged'ge is fully line-spaced to its correspondinggage. With the platen in its displaced position, thejearl- In order that, when the platen is ing edge of .the active web is therefore brought up to its gage, said web moving relatively to the interleaved carbon-sheets. In order to withdraw the carbon-sheets, the leading edge of the active web is held with one hand againstthe gage while the, carboncarriage is moved rearwardly to the stop 83 by pushing the handle 31. \Vhile the carbons are moved rearwardly, the idle web is also moved along due to the friction of the carbons and clips against the several plies of' theweb, the idle Web being free to move alongwith the carbons while the active web is held during the displacing of the carbons. The carbon-carriage stop is so positionedthat when the carriage is brought up to said stop, the leading edge 64 of the inactive web will project beyond the knife 67, as shown in Figure 8. Furthermore, the leading-edge ga e 44 is so adjusted that when the active we is pulled up thereto, the perforations of the typed sectional form will be in alignment with the leading edge of the inactive Web; in other words, the distance from the knifeedge to the leading-edge gage will be greater than a sectional printed form of a ply by the distance the leadingedge of the inactive web projects beyond the knife. v

lowered td its normal or effective position, the webs may not he accidentally shifted out of place,

there is provided a clamp designed "to hold the webs fast against the front table 46. Said clamp comprises a cross-bar 49 pivotally mounted upon the shaft 13 by means of brackets 50which form an integral part of said clamp and are rotatably held on the shaft 13 by means of pins 51. The clamp is provided with a pin 52 which forms an integral part of a handle 53 for operating the same, and the pin cooperates with a latch 54 pivotally mounted upon the frame 11 at 55 and is held by a spring 56. against a pin 57 also fast to the frame 11 As shown in the drawings the clamp is provided with means whereby webs of different thicknesses may be effectively clamped, said means comprising a plurality ofresilien't plugs 58 fa l: to the cross-bar 49 and a flexible piece 59 connecting the clamp and "the latching means. The latch 54 is operable by forcing the same rearwardly away from the pin 52 to releasethe clamp.

Referring more particularly to Figures 7, 8, 9and 10, it will be noted that in Figure 7 the latch 54 is shownv in its ineffective I position and the. platen lowered and held against the feed-rolls by means of latches 48 held in engagement withpins 60 by'the springs '61, which swing the latches forwardly on a rock-shaft .62. The two webs 34 and 35, aligned abreast of each-other are shown completely fed around the platen and the carbon-carriage 30 is consequently shown in its forward position, near the platen, at

the table 40. The backwardly to a position as shown in Fig,-

the end of its travel. Figure 8 shows the platen swung forward resting on a front stop 63 on the carriage. The carbon-carriage 30 isshown in its extreme rear position against a stop or gage 83 in which position it will be after displacing the carbons into aglew position covering a fresh section of the-web. It will be noted that the leading edge 64 of the idle web is shown displaced relatively to the leading edge 65 of the active web, the latter being held when displacing the carbons, while the former is permittedv to move rearwardly with the carbons. In Figure 9 the clamp is shown in its effective position having been lifted by means of the handlev 53 from the position shown in Figure 8, in which it is resting on a stop 66, to the position shown in Figure 9 in which the pin 52 is thrown intoengagement with the latch 54 to resiliently hold the webs clamped'between the bar 49 and laten is then thrown ure 10 in which the pin 60 engages the latch 48 and holds the platen against the-feedrolls. The latch 54 is then released by forcing the same rearwardly so that the clamp may be swung forwardly to a position as shown in Figure 7. To bring the aligned leading edge of the inactive web and thesigned, in the preferred form, to be detach-- ably mounted upon the carbon-carriage 30. To this end there is provided an adapter plate 69 which'is secured to the carriage 30 by means of the regular clamps 70 engaging slots 71 inpins 72 which form an 1ntegral part of the plate 69 and fit into, holes 73 in the carriage 30. Upon the adapter llO plate 69 there are mounted the two frames 68 whichin turn carry the carbonclips 74 fast thereon. Said frames 68 are detachably mounted upon the adapter plateby means of pins 75 having slots 76 engaglng with looking bars 77, of which there are two to facilitate the individual removal of either ofthe carboncarrying'frames 68. The bars 77 are operatively mounted in slots out into downwardly-extending tabs 78 which form an integral'part of the adapt-er plate 69. To

release the frames it is only necessary to pull the bars outwardly to the end of their travel, which is limited by the'pin 79 striking the tabs,7 8 so that the notches 80 in the 7 3 to be engaged by the clamps 70 fitting into.

slots 88 in the pins 87. In Figure 4 there is shown a'diagrammatic view of the webs and the carbon-clips 74 in the preferred form.

Said clips are shown fastened by one of their ends to the frames 86 while the other end is. shown interleaving the plies of the web-s.

One of the features shown at Figure 6 is that the stock parts in the regular fanfold machine are used with little or no alteration thereof. This consists in alternately disposing long and short carbon-clips respectively numbered 89 and 90, both kinds of clips being fastened at the outer supports 91 and having no support in the center. The two'end supports are fast to a plate 95 which i's in turn attached to the carriage in the regular manner. There is pro- 30 vided a special web-gage 92 at the center fastened to the plate 95 by means of a screw 94, and at the ends the web is guided by the regular gage in the fan-fold machine indicated by numeral 81 throughout the several e views.

Another feature of this device is that the same may be converted into a regular singleweb fan-fold machine for wide webs, by simply changing the carboncarrying frames 40 and by swinging the web-guides 41 on the shafts 33 and 62 to the idle position shown in dot-and-dash lines (Figures 1. and 11). The guides are then fastened by means of thumbscrews 96, so that the single wide web is 45 then guided between the outer guides 98, the central guides 81 and central frames 86 at Figure 5 being also omitted.
