' TYPEWRITING MACHINE.

Appli c ation filed August 14, 1923. Serial No. 657,291.

This invention related to :manifolding typewriting machines ofthe continuous billing type, in which a composite sheet or web,

placing or shifting between the carbon-sheets and the work-sheets. I l In practice, it hasbeen. found imprac ti cable to shift the carbon-sheets relatively to the work-sheets while the carbon-sheets and the work-sheets are bent short, as, for

example, around the platen which is of'comparatively small radius. In the Underwood continuous billing machine, shown in the 1 patentto VVernery & Smith, No. 1,132,055,

dated March 16, 1915, the platen is displaceable upwardly by means of a swing frame, so that that portion of the web containing the carbon-sheets may be straightened out preparatory to displacing the carbon-sheets relatively to the work-sheets. The carbonsheets extend forwardly from a carbon-carrier, which may be moved rearwardly while the Work-sheets are moved forwardly to a gage, after which the platen maybe lowered to its normal typing position. The typed set of forms may then be severed and the typing of a fresh set of forms may proceed. I 1 It has been found that that portion ofthe web containing the carbon-sheets may be so conditioned thatthere may be caused a relative shifting without lifting the platen, in other words, while the platen remains in its usual typing position. To. this end, there has i been proposeda curved table at the rear of the platen over which theweb is conducted and from which it" extends tangentially to the-platen. One form of this arrangement'is shown'in my co-pending app p sheets relatively to'the-carbon-sheets, a gage 2 v plication, Serial-No. 642.961, filed June 2,

1923 (now Patent No. 1,5 74,215,dated February 23, 1926), in which the table forms part of a cylinder of a comparatively large radius. &The table always occupies a fixed position relatively to f the platen, and a cal,- 1

hon-carrier. travels over saidv .table toward the platen during line-spacing operations. After a form has been completed, the web may be withdrawn around the platen by I moving the carbonrcarrier' over said table and away from the platen until the leading edges of the carbon-sheets have been freed'from said platen. The work-sheets are then fed forwardly while the. carbonsheets are held to thus strip the carbon-sheets from the typed; set of forms and bring them to'a fresh set or untyped set of forms.

In the present invention a curved table and a carbon-carrier are used to condition the web for a carbon-displacing operation. An object of the present invention is to lower said tableafter a carbon-displacing opera: tion, so that there may be created in the Web behind the laten sufficient slack which may readily, be taken u during the linespacing of said web around thepl aten, thus avoiding any hindrance to the web during line-spacing operations, which may be occasioned without slack insaid web.

Inthepresent invention, after a form has been typed and it is desired to prepare the web for a carbon-shifting operation, the curved table is rotated. about its pivot to thus take up the remaining slack in the Web and also draw the web from a source of supplyv as the table approaches its operated position.

According to the extent to which. the web" has been fed around the platen, the,carbon-' carrier will also be drawnupwardly from its normal position during the upward rotation of the table. After the table has reached its operated position, the feed-rollers may be cast off and the carbon-carrier may then be actuatedto return it to its normal position to thus draw the web around the.

platen until the leading edges of the carbonsheets are freed from the platen. The feedand the carbon-carrier: is held in its normal laten may befrot'ated to advance the workbeing'. provi d-e t e ntrodu te r s d o therplaten to determinethe extent ofrelative av e sh f d; e; urved. tab y be ts normal PQSit'iQJ s. :1:-

thus producing slack in the web, which may be taken up during the line-spacing "of the web around the laten. The web is then fed to bring the leading edges of the work-sheets to a second gage to t-nus bring the carbonsheets to the nrinting pointand the bottoms of the typed forms to a knife where they mav be severed. Typing of thefresh set of forms may then be proceeded with. Operating handles are provided for the web-conditioning table and the carbon-car rier, and are supported on a sub-carriage connected to travel with the tv-newriter carriage, said sub-carriage swmorting also said tab e and said carbon-carrier. Other features and advantages will here inafter appear.

In the accompanying drawings, Figure 1 is a part sectional side view of an Underwood typewriting machine, showi'ngj-the invention applied thereto, the parts being in position during typing operations. Figure 2 is'a top plan view of the ma chine, with the par-ts in the position shown in Figure 1. 7

Figure "3 is a view similar to Figure 1, but shows the web-conditioning table in its raised position {and the carbon-carrier drawn forwardly thereby, the feed-rollers still holding the web against the platen.

Figure a is a view similar to Figure 8, but shows the feedrollers released and the carbon-carrier returned to its normal positi-onto withdraw the web around the platen to free the carbon-sheets from the platen preparatory to advancing the work-sheets. Figure- 5 is a view similar to Figure 4;, with some of the parts omitted, the parts occupying the same posit-ions as in Figure 4, except the feed-rollers which are thrown on and have assisted in advancing the worksheets, with respect to the carbonsheets, to the first gage.

Figure 6 is "a view similar to Figure 4, but shows the slack produced in the web behind the platen after the table has been lowered, the web having been fed to the second gage to bring the carbon-sheets to the printing point and the bottoms of the typed forms to the knife where they may be severed.

Type-bars 1*0 strike against the front of a rcvolu'ble platen 11, which is journaled in the usual manner in a platen fraine coinprising ends 12 and a rear asper-shelf 13. The usual front and rear feed-rolls 14 run on the under side of the platen. 'They may be released, or thrown from the platen, by niece 15, connected by a means of a finger-1 link 16 teen arm 17, fast on a shaft 18.

The shaft 18 is provided with flats, against which ns 19, forming part of leve'rs 29, held by spring-pressure. The levers are 20 are a vot d on a 'sh-aft 21 so'tha't, when e i5 is actuated, and the arms.

19 spread apart by turning of the shaft18,-

the levers 20, which "support the pressurerolls, are rocked on the shaft 21 to release the rolls. This roll-releasing structure is that commonly found in the standard Underwood t-ypewriting machine,

The work-web, usually comprising superposed plies 22 (which may be separate or which may form a fan-fold), is drawn up from a supply-spool, or from a zigzag folded pile (not shown), but which may be contained in a receptacle atranged in the rear of the typewriting machine and its stan-d28. As the plies of thework-web rise from the supply at 24, they first pass through a carbon-carrier 25; and are there interleaved with the carbons 26. Each of the carbons 26 has its'rear end attached to one of two blades '27, carried by standards 28 on the ends of a plate 29. The plate 29 is secured to a bar 30, supported at its ends by a pair of arms 81, one on each side of the machine, loosely pivoted at 32 on stub-shafts 33, journaled in the side pieces 34lof a frame or subcarriage which is connect-ed to the platencarriage for movement with the latter in letter-feed and return directions. The purpose of the pivotal mounting of the carboncarrier will hereinafter more fully appear.

The side pieces 34- of the sub-carriage, which pieces are shown, in Figures 1 and 3, as of general triangular formation, are tied together at the front of the sub-carriage by a bar 35, which is secured by screws or rivets 36 to lorackets 37, in turn secured at 38 to the usual rear cross bar or tie 39 of the platen carr'iage. The platen ca-rriage is supported in the usual way upon a rail 4-0 on the main frame ll of the machine movement in letter-feed and return 'directions. The sub-"carriage side pieces 34 are connected at the rear of the sub-carriage by a bar or tie 4-2, from which depend-a pair of brackets 43, having rollers 44 thereon which ride on rail supported on the rear of the table 23 which. supports the ma chine. Ears 46, offset from the brackets under the rail 4-5, serve to hold'th-e sub-- carriage down on the table 43.

hen the parts are in typing position, the work-plies 22, interleaved with the carbons 26, pass upward from "the carboncarrier over a roller 49, and thence forward to and over a roller 50,; journaled at 51 in the sid'eplates 3io t' the sub-(Jerri ge, above and at the rear of the paper-table 13; the roller 50 beii-ig so located that the comp 'e web may pass 'tangentiaily therefrom, down over the table 13 to the rear under face of t he platen, whence it is guided around the platen, up across the printing line, and

means of the rack 65, pinion 67, and pinion 69, 1is swung clockwise, looking fromthe left, rflfomFigurejl. to Figure 3 position. The table 56 is arrested in its Figure; 3 position by .the engagement :of the right-hand tablesupporting arm 59 with a stop-pin 73 on the right-hand: side piece 34 of the Sub-carriage. For holding the table. 56 against accidental displacement, in Figure 3 position, there is provided aspring-latch. This latch consists ofa belljcrank lever 71,1pivoted at 72 to'the rightrhandltable-arm '59, and having anose 74-. adapted to be snapped over the stop-pin 73.; A-spring '75, connected at one end to thelatch-leverf71,, and at its other end to the ,"tableaarm'59,-holds the latch in a normal position, determinedby a stop-pin. 71 on the table-arm .59, and returns-the latch to such stop-pin, after movement of the latch, upon release of the latch to the action of. the springa75. When thetable comes to Figure 3.,position, the pin 7 3 cams: the latch back ward against the action of the spring 75,. to.1permit. the nose oft-helatch to pass the I stop-bins When thenose of the latch is past the stoprpin,,the spring 75 acts'to lock the table in place' It .is noted, upon reference tothe draWings,-that.the nose of thelatch,

that, when the-table is in Figure 3 position,

the composite web extends tangentially from the forward endof the table-,to the platen.

the form-sections.

however, the carbons are secured to the carbon-carrier, the latter should be free to move upward, during the Figure l to Figure 3 movement of the table, a "distance sufficient to accommodate the carbons to the Figure 3 position of the table. The loose pivoting of the carbon-carrier permits the latter to'be swung by the pull of the table 56 on the web. The distance to which the carboncarrier win he swung during the movement of the table, from Figure 1 to Figure 3 1 the latter, is, however, a movement which is determined by, and equal'to, the length of Preliminary to the actual form-to-form shift of the work-webs, with respect to the carbons, the pressure-rolls 14 are released,

' and the carbon-carrier, with the carbons and work-webs, is moved f-romFigune 3 position to another, Figure 4, position, to clear the carbons from the platen, so that, as presently to be described, the workwebs may thereafter be fed forward by the platen and the pressure-rolls without forward feed of the carbons. This movement of the carboncarr-ier, with the carbons and work-webs, to release the carbons from the platen, and to fix the position of the carbons for a subse quent forward feed of the work-plies with 'respect thereto, is accomplished by the following means. g

The right-hand carbon-ca rrier arm 31 has a rack 77 formed thereon, concentric with its axis of rotation 82. Journaled at 78, on the right-hand side piece 84 of the subcarriage, is a pinion 79, in mesh with the rack 77.- Also jou'rnaled at 80, on the same sub-carriage side piece, is a rack 81, to which is affixed an operating lever 82. In the movement of the table 56, from Figure 1 to Figure 3 position, and consequent movement of the carbon-carrier, as aforesaid, from Figure l to Figure 3 position, the rack '77, acting through the pinion 79 and rack-81, throws the carbon-c-a'1 '-rieroperating lever downward, as indicated in the drawings, thereby setting the same for the stroke thereof which is to release the carbons from the platen by retraction of the web. To return the carbon-carrier to its normal, Figures l and 4, position, and release the carbons from the platen, preliminary to actual form-to-form shift of the work-webs, with respect to the carbons, the

handle 82 is swung up, as indicated in F igure 4. At this time the table 56 is held fiipin 83, on :the lleft-hand subsearriage side piece 34, by engagement with the left-hand carbon-carrier arm 31, determines the normal, Figures 1 and '4, position oit thecarhoncarrier, and determines the throw of the latter, from Figure 3 to Figure 4 position, to release the carbons from the platen- The web being laid out smoothly on the table 56, the Figure 3 to Figure 4 movement of the web is easily effected.

After the web is in-Figure 4 position, the form-to-form shift iOf the work-plies, relative to the carbons, may be effected, by'forward feed of the #work plies' around the platen fa distance'equal to :one form-length. For effecting 'sufch forward shift of the wo1'k=webs, it is merely necessary to reapply the feed-rolls 14 and to turn the platen :by means of one :"of the hand-knobs 84 crimespace wheel 85, ordinarily found. on the platen-axle. During this operation, the hand-lever 82 is held hy the operator, in Figure 4 position, to prevent advance "of the carbons with the work-plies. The lower end 86 (see Figure 5) of an arm '87, unitary with the gage 54, serves to'determine, by the registration therewith of the vileaic'lin g ends of the work-Tplie's,-the amount of advance of the work-plies required to properly position the carbons in the next untyped formsections of the work-plieaand to clear the carbons of the leading typed form-sections for detachment of the latter. Y

It remains then to advance the composite web to position wherein such detachment of the leading typed form sections may be offooted, and to position the web for commencement of typing on the nextuntyped form-section thereof. "It is for this purpose that the gage 54 is provided, as shown in Figure '6'. The movement of the composite web to bring the leading ends of the work-webs to the gage; 54 is effected by a furtherforward rotary movement of the platen. Prelimh nary to such further forward rotary movement of the platen, and in order that the carbons may be advanced with the workp-lies during such niov'e-i-nent, and without movement 'of the carbon-carrier, the handle 64 is thrown to Figure .1 position, to return the table 56 to Figure 1 position, thereby re est'ablishing aslack in the web plie's and carbons. Sti e-h reestablished slack will be not only sufficient to permit advance of'the web, from Figure 5 to Figure 6 position, but will also he sufficient to take ca re of the subsequent line-space feed of the web in the typing of the text form. ,'Th, 15ievent catching of the web on-the tab-1e 56,"i' n the return of thelatter-"to'Figure'l positiong' thez rear edge 56 of inward.

secured to the end pieces ,12 of the platenframe. Thebrackets 89 also serve to sup porta cross-plate 90, to which the gagestatf 52 is centrally secured at 91.

Figures- 1 and 3, thatin all (positions of the rotary table or shell 56, an ofthe carbon-carrier,

both these elements are above the platform,

23 which supports the machine, so that the, platform may be extended ihorizontallyrearward to the support, thereon for the sub-carriage. It willalso be noted, that no space between the rotary table and the fjmachineis required for the slack in the-web; the concavity of the table or shell 'itselt providing the spacefor the slack. Since the table or shell and the carbon-carrier re. 7 quire no more space in the Figure 1 position than in the Figure 3 position thereof, and i1 since the means for actuating these devices, may, ineffect, belocated within the-she'll or 7 space which the latter occupies; and since;

the web may be led directly and snbstan Ltially vertically'up onto the carbon-carrier or table, the whole presents an extremely compact structure,requiring no space below the machine-platform, and; requiring a space only slightly greater than'thediameter of shell at the rear oi the machine. i
