Application filed August 9, 1323. Serial No. 6 5 6, 545.

This invention relates to .manifolding typewriting machines of the continuous billing type, in which a composite sheet or web is fed around a cylindrical platen, the .web comprising several pliesof work-sheets having successive corresponding forms printed thereon, said plies being sometimes ,sena rated from each other, .and sometimes joined ;at';their side edges team a folded web, the various plies having carbon sheets interleaved therebetween, which are fdisplaceable at intervals alongthe web ,to fresh sets of untyped forms. The invention relates more particularly to means to facilitate the relative displacing or shifting ,between the carbon-sheets and the worksheets.

Qne form of machine forhandling this kind of work is disclosed in the patent to Ternary & Smith, No. 1,132,055, dated March 16, 1915. Said machine comprises a cylindrical platen mounted in a swing- :frame, :by which it may Joe'raised to an abn a po ion, from i s n ma typing po- .sition, to facilitate the straightening-out of that portion of the web containing the carbon-sheets, so that the displacing of .the carbon-sheets and the worksheets may be readily effected. I

Another form of this general typeof machine is disclosed in my co-pending application, Serial No. -,65,0,615, filed July? 10, 1923, in which that portion of the web containing the carbon-sheets is so conditioned that there maybe effected a relative shift.

ing between the carbon-sheets and the worln sheets, without shifting the platen, the platen remaining always in its .normal typing position. To this end, there is provided, in the machine of my aforesaid co-pending application, means for withdrawing the web completely from the platen, thus to bring ,it to a straightened-out position so that the work-sheets may be drawn forwardly, while the carbon-sheets are held, .to shift .them relatively to the carbon-sheets. table is provided, in the machine of my aforesaid co-pending application, having a pivoted section which may be swung to bring the web to a convenient gaging and tearing-off position, said table being also effective to render effective certain devices to prevent accidental forward movement of the carbonseh fi uring a Worksh -gag ng operation and .to hold the work-sheets against accident al displacing during the tearing-off operation. Said machine also I includes means for rapidly reinserting the .web around the platen, there being provided, for this purpose, web-feeding means to advance the web against a guide disposed at the back of the platen to conduct the leading edge of the (web downwardly around the platen.

A feature of the present invention is the provis on of feed-rollers for reinserting the work-web around the platen, said feed-rollers being effective not only .to advance the.

wards the platen.

A further feature of to a novel arrangement of sheet-gage and knife, and a connection by whichthey may be operated bya single handle.

Still another feature of the invention relates to novel means for preventing accidental forward movement of ,the carbon-sheets during .awork-sheet-gaging. operation, there being provided, for thispurpose, means connected with ,the gage-operating handle to I ebbut also to conduct it downwardlytoco-.operate with the carbon-carrier-actuating handle to hold the carbonecarrierin its retracted position when the gage is swung to .its effective position.

the invention relates A further feature of the invention resides in means comprising a clamp to hold the work-sheets to prevent accidental forward movement thereof during a form-severing operation, said clamp being operable by a further movement of the gage-operating handle, .said movement being effective-to bring the knife to its fully operated or effectiveposition after the sheets have been gaged. The knife and the gage are so disposedthat the web may .be severed bydrawand shows the feed-rollers cast off and the web completely withdrawn around the platen to free it from said platen; the web having also been brought to a straightened-out position preparatory to a work-sheet-shifting operation.

Figure 4 is a View, similar to Figure 3, with some of the parts omitted, showing the gage swung to its effective position, the work-sheets shifted relatively to the carbonsheets, and the carbon-carrier-actuating handle held against forward movement to prevent accidental forward movement of the carbon-sheets during the worksheet-gaging operation.

Figure 5 is a view similar to Figure 4, and shows the gage-operating handle moved further from the position shown in Figure 4 to completely actuate the knife to bring it to its effective position, and also clamp the web so as to prevent accidental forward movement of said web during the form-severing ope *ation, the typed forms being severed in this figure.

Figure 6 is a diagrammatic sectional side view, showing the leading end of the web bent downwardly towards the platen by a preliminary movement of the web-reinserting handle.

Figure 7 is a view similar to Figure 6, and shows the web-reinserting handle completely actuated to advance the web around the plat en to the printing point. i

The invention is shown as applied to an Underwood standard typewriting machine, in which typebars 10, when operated by keys, not shown, swing upwardly and rearwardly to print against the front of a cylindrical platen 11, mounted on a carriage 12 comprising end bars 13 connected to each other by a rear bar 14 and a front bar, not shown, said carriage being mounted for let ter-feed movements on a rear rail 15 and a front rail, not shown, said rails being supported on the main frame 16 of the machine. The platen is secured to a shaft 17 ournaled in end plates 18 of a platen-frame 20, said end plates being secured to each other by a bar 21 and a rear paper-table 22, over which a composite work-web 23 is led from the back of the machine to the rear and beneath the platen where there are provided

feedrollers

24 and 25 to assist in feeding the work-web around the platen. The platen may be rotated by a finger-wheel 26 or linespace wheel 27, the latter being operable by suitable line-space mechanism, not shown. The platen-frame is supported on the carriage-franre for case-shifting movements in the usual way to present the platen to lowercase types 30 or upper-case types 31 on the type-bars. The feed-rollers may be released by mechanism operable by the regular feedroller release-handle 28, so as to provide an unobstructed path around the platen when adjusting the work-web around the platen.

The attachment comprises a horizontal table 32 extending rearwardly from the ma chine, and over which the composite web 23, comprising work-sheets 33 with interleaved carbon-sheets 34, is conducted to the platen. The table 32 comprises end bars 37 connected to each other by a front crossbar 10 and a rear cross-bar 11, and is supported to travel with the carriage 12. The table 32 1s connected with said carriage by rearwardly extending brackets 42 secured to the under side of the carriage-bar 1 1 and to the under side of the crossbar of said table. The table 32 is supported at its rear by means comprising brackets 43 secured to the end bars 37 thereof. The brackets 13 have rollers to run on a rod 15 secured to a frame comprising two end plates e6 extending rearwardly of the main frame 16 of the typewriter.

The two end bars 37 have rails 52 secured thereto to guide a carbon-carrier 53 towards and away from the platen. The carboncarrier comprises a base-plate 54, to the under side of which are attached four rollc1355, two at each side of the machine, to run on the rails 52-. The carbon-carrier further comprises stepped uprights 56, one at each side of the machine, on which carbon blades or holders 5'? are detachably mounted. said carbon-blades having the rear ends of the carbon-sheets 34 connected thereto. The work-web, which may be fan-folded or be composed of separated plies, may be conducted from any suitable source of supply upwardly at the rear of the machine to a turning bar 60, supported by standards 61 and provided with suitable end gages 62 for the web 23. The web is then conducted forwardly through the carbon-carrier and over a roller 63 toward the platen The roller 63 is journaled in the forward ends of the end bars 3'? of the table 32. Suitable end gages 64: on the bar 40 further guide the web. From the roller 63 the web is conduct ed downwardly to the platen, between the feed-rollers and 25 and upwardly at the front across the printing point, where the web may be held against the platen by the usual wing-scales (not shown) anl one or more fingers 59 extending rearwardly towards the platen from the usual front rail of the carriage.

As the typing of a form proceeds, the carbon-carrier 53 travels towards the platen on the table When the typing of a form has been completed, it is desirable to sever the typed forms from the work-sheets. Before this is done, however, it is necessary to shift the carbon-sheets relatively to the worksheets to a fresh set or untyped set of forms. T 0 do this, the composite web is withdrawn around the platen to free it from the said platen, so that that portion of the composite put web including the carbon-sheets 34 may be brought to a straightened-out position, the platen retaining its usual typing position, after which the work-sheets maybe shifted relatively to the carbon-sheets.

lVhen it is desired to straighten out the composite web, the feed-

rollers

24 and 25 are first cast oil by depressing the usual teed-roller release-handle 28. The carbon carrier is then pushed rearwardly by means of a handle extending forwardly therefrom until it is arrested against a fixed stop 66 on the end bar 37, the parts being arrested in the position shown in Figure 3, where the composite web has been cleared from the platen and has sprung up into a horizontal, straightened position, with the leading edges of the work-sheets over the platen where they are accesible to, and Ditty be grasped by the operator, and with the web resting on the roller 63.

The next step is to set a gage for determining the position to which the leading edges of the work-webs are to be drawn, while the carbon-sheets are held stationary, in eii'ecting the torrn-t'o-form shift 01" the carbons relative to the work-webs, and in clearing the typed leading forms of the work-webs of tliecarbons, so that such typed leading forms may be detached from the rest of the worlnwebs. This gage 70 is shown as adjustably secured to a staii" 71, fast on a rock-shaft 72, pivoted in fixed brackets or plates 73 over the front of the platen-frame. The brackets 73 are secured by screws 74, one to each of the bars 37 of the frame The normal position of the gage and gage-staff is that shown in Figure 1. The perative position of the gage is tl it shown in Figure l, in which the gagestafi' is shown as having been swung to a substantially horizontal position iroin a substantially vertical, Figure 1, pos.ition,and in which F1 u'e position the 70 is shown as l ing vertically across thehori- Zontal i n. For eii'c-ct-ing the throw of the gage i'roui figure 1 to Figure +iposition, to the right-hand end ot'the an arm v75, connected by a a plate 77 made first to a rockalso jouriialed at its ends in the oi the 8 is a lever 79, by means of which the shaft 78, plate 77, link 76, arm 75 and rock-shaft 72 may be actuated, by upward throw or" the lever 79, to throw down the gage-stat? to Figure 1} position. ii' hen the gage 70 is in its Figure 4 position. the leading edges of the work-webs, beyond the leading edges of the carbonshcets. inav be'seized; by the operator and drawn "forward to the gage. 1

l hen the'worlrewebsare thus drawn for ward, the-carbons shouldbeheld stationary path .ot the work-webs over the Fastto the lett-hand end in their Figure 3 position. This might be done by "he operator pressing rearward, with one hand, on the forward end of the handle 65 on the carbon-carrier. To relieve he operator oi this duty, however, means provided for automatically locking the carbon-carrier in its Figure 3 position when the lever 79 is thrown from Figure 1 to Figure i position. Such means is shown as a rearwardly-extending arm 80, forming part oi the lever 79, and having a stop-piece 81 the eon, which, as shown in Figure 4, blocks the path oi? the finger-piece 82 on the end of the carbon-carrier arm 65 to prevent forward nioveinent of the carbon-carrier when the work-webs are pulled forward to Figure 1 position. r v

Aiter tne work-webs are in Figure 4 position, it is usually desirable to sever the typed leading tornisthereoiil This is ef-.

i'ected by means of a knife-blade 83, which has a normal position, shown in Figures 1 and 3, well out the way of the web, above I plate 84; fast to the rock-shaft 78, so that,

when the handle 7%) is thrown up to lower the gage-staff, the knife 83 is also lowered to'the horizontal Figures 4; and 5 path of the web; As indicated in Figure 4-, however, a pos Figures 1 and positions, is provided, in which intermediate position the knife-blade is at a slight incline and somewhat. to the rear of the leading edges of the work-webs 'lJQlOIQ hey have been drawn to the 70.. his intern'icdiate position of the knit.- hlade permits the work-webs to be grasped, as above stated, for the .fOID1-tOfO1DI1 shift of the same relative to the carbons. Such relativ form to-torin shitt ot the webs and carious having been effected, however, the knife, by a further upward vein it or the handle 79, may be brought from Figure 4 to Figure 5 position, Owing to the length of the stop-piece 81 on the rear arm of the lever 79, this further upward movement oi"? the lever will not clear the stop-pieii-efil from the path of the end oi the carboncarrier-operating arm 65, and, therefore, accidental torwarr displacement oi the carboncarrier canuot take place, such as might. otherwise result inblocking the return of the lever 79 to its norn'ial,Figure 1, position.'- Furthermore, by reason of. the con-- tinuedpresence ofthe stop 81in thepath 'tion the hnii e 83, intermediate its iLEU of the carbon-carrier-operating arm 65, the carbons cannot be displaced forward during the operation of drawing the webs against the knife 83, as shown in Figure 5, to sever the leading typed form-sections. The full throw, to Figure 5 position, of the lever 79, and, consequently, the e'tl'ectove position of the knife 83, is determined by means presently to be described.

Prior to severing the leading form-sections of the w rk-webs, it is desirable not only that the carbons be held against forward displacement, but that the work-webs themselves be held against such displacement. Consequently, a clan'iping bar 36 is provided, between which and a bar 87, supported on blocks 88 on the table-rails 37, the composite may be clamped at the proper time. The clamping bar 86, supported at its ends by arms 89 fast on a rock-shaft 90 journaled in the bracket-plates 73, is normally held in Figures 1 and 1 positions above and out of the path of the web. The effective position of the clamping bar 86 is that shown in Fig ure 5. For throwing the clamping bar to Figure 5 position, the handle 79 is again conveniently utilized; and the connection from the clamp-bar-supporting arms 89 to the lever 79 is by means of a link 91, connected at its rear end to an arm 92 forming a bell-crank with the right-hand arm 89, and at its front end bearing a pin 93 working in a slot 9 1-. in the right-hand knife-supporting plate 77. It is obvious that, when the gage is thrown to Figure 4- position for the forward shift of the work-webs, the clamp ing bar 86 should not be effective to perform its function; otherwise, the clamping bar will prevent the forward shift of the workwebs. It is for this reason that the pin-and-slot connection 93-9i is provided between the link 91 and the handle 79. This slot is of such length that, as the handle is moved from Figure 1 to Figure 1 position, the pin 93 traverses the slot 941 without move ment of the link 91. Further movement of the lever 79, from Figure t to Figure 5 position, for setting the knife, after the forward shift of the work-webs, results in a pull on the link 91, because, as shown in Figure 1, the pin 93 is then at the rear end of the slot 94-. This pull on the link 91, by movement of the lever 79 to Figure 5 position, results in the clamping bar 86 being rocked down against the web to hold the latter fixed against the plate 87. The leading typed section of the web may then be seized and drawn against the blade 83, without possibility of suchmovcment of the web behind the blade 83 as might affect the accuracy of the cut. Engagement of the clamp 86 with the plate 87 determines the upward throw of the lever 79 and effective position of the knife 83.

The handle 79 is then rocked downward from Figure 5 to its normal, Figure 1, position. This normal position may be determined by engagement of the rear edge of the right-hand knife-carrying plate 77 with a stop-pin 95 fixed on the adjacent bracketplate '73. A coil spring 96, having one end hooked over the upper edge of the righthand bracket-plate 7 3, and having its other end hooked over the front edge of the adjacent knife supporting plate 77, may act to return the parts to normal position when the lever 79 is released, and to hold the same in normal position against displatement. During the early portion of this return movement, the. knifeblade 83 and clamping bar are first returned to Figure a position. 'lhereafter, the lever 79 moves without movement of the clamping bar; the pin 93 mercy noving to thefront end of the slot 9 1 as the lever 79 completes its throw. he front end of the slot 91 may serve to determine the normal position of the clamping bar. When the lever 79 is in its normal position. the carbon-carrier is free for forward movement, so that the composite web may be fed down behind the platen and around the latter, to position for commencement of writing.

As a preliminary to positioning the composite web for commencement of writing, the same is bent downward over the paper-shelf 22, forward of the roller 63, as indicated in Figure 6. This bending of the web is effected by movcn'ient of a roller 97, from Figure. 1 to Figure 6 position, against the roller 63. The roller 97 is journaled-on arms 98 made fast to a rock-shaft 99, in turn journale'd at itsends in the bracket-plates 73. Forming a bell-crank with the right-hand arm 98 is an arm 100, in the end of which is journaled a stub-shaft 101. Fast to the shaft 101 is an operating lever 102; and also fast to the shaft 101 is a segmental rack 103, the purpose of which will present appear. A coil spring 10% connects an ear 105 on the segmental rack 103 with an ear 106 on the lever 98. The tension of the spring 104 is such as to prevent rotary movement of the segmental rack 103, stub-shaft 101 and lever 102 on the arm 100; so that a downward pull on the lever 102, from Figure 1 to Figure 6' position, simply causes rotary movement of the lever 102 and rollarrying arms 93 as a unit with the rockshaft 99 around the axis of the latter, un-

til the roll 97 bears against theroll 63. The roll 97, in its movement to the roll 63, stri es the horizontally-projecting end of the composite web and deflects the same from Figure to Figure 6 position.

On reference to Figure 6, it will be noted that forward feed of the web from the position therein shown will result in movement of the web around under the platen, between the latter and the then released feed-rolls 24 ion and 25. This feed .of the composite web, and the extent of such feed to properly position the web for commencement of typing, are effected and determined by the following means: The rack 103 is in mesh with a pin ion 107 concentric with and fast to the roll 97. Owing to the strength of the spring 104, as hereinbefore set forth, no. rotary movement of the rack 103, and, consequently, of the pinion 107, takes place in movement of the operating lever 102 from Figure 1 to Figure 6 position the ,parts, up to this time, turning on the axis 99. Upon engagement of the roll 97 with the roll 63, however, further movement of the lever 9-8100 on the axis 99 is prevented; and, thereafter, further pres sure on the operating lever 102, sufficient to overcome the tension of the spring 104, results in the rotation of the stub-shaft 101, and consequently, of the rack 103. Such rotation of the rack 103 causes rotation of the pinion 107 and of the roll 97. The roll 97 being pressed against the roll 63, with the welo between the same, and being rotated by the pinion 107, there results aforward downward feed of the composite web fromFigure 6 to'Figure 7 position. The Figure 7 position which is the position of the web for commencement of typing, is determined by engagement of the forward end of a slot .108 in the rack 103 with a pm 109 which projects into the slot 108 from'the lever-arm 100. Upon release of the lever 102, a coil spring 110, having one end thereof hooked under the right-hand roll-carrying arm 98, and the other end thereof hooked over the adjacent bracket-plate 73, lifts the arm .98 and rotates the rock-shaft 99 to release the roll 97 from the roll 63. The spring 104, when the handle 102 is released, return s,the handle 102 and rack 103 from Figure 7 to Figure 6 position; the pin 109, by engagement with the opposite end of the slot 108, determining the Figure 6, or normal, position of the rack and operating lever 102 on the leverarm 100. A stop-pin 111 on the right-hand bracket-plate 73, by engagement with the upper edge of the right-hand roll-carrying arm 98, determines the Figure 1, or normal, position of the roll ,97 and associated parts. It will be noted that the spring 104 is stronger than the spring 110, sothat the latter yields to permit movement of the parts as a unit around the 2LX1S99, from Figure 1 to Figure 6 position, before the former yields to permit rotation of the handle 102 vand rack 103 around the axis 101. The feed-

rolls

24 and 25 may then be re-appliedto the platen. and typing commenced Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
