rYrEwmrme nacnmE.

Application filed June 80, 1923. Serial No. 848,705.

" ,This invention relates to manifolding forms to afresh set of forms.

typewriting machines of the continuous billing type in which a continuous composite web is fed around a cylindrical platen,the composite web comprising several pl1es of work-sheets having successive correspond ng forms printed thereon, said plies bein sometimes separated from each other an sometimes joined at their side ed es to form a fan-folded web, the various pies having carbon-sheets interleaved therebetween. The invention relates more particularly to means to facilitate the relative displacing or shifting between the carbon-sheets and the worksheets, or, in other words,

the carbon-sheets. from the t ped set of he invention further relates to means for determining the relative shifting between the carbonsheets and the work-sheets.

In the Underwood continuous billing ma chine, shown in the patent to Wernery and Smith, No. 1,132,055, dated March 16,1915,

in which a cylindrical platen is employed,

it has been the practice to displace the platen upwardly by means of aswing frame, to permit the'composite web to be straightened out preparatory to displacing or shifting the carbon-sheets along the work-sheets to a freshset of forms. There is also employed in said machine a table extending rearwardly. from the platen upon which a carbon carrier is mounted to travel back and forth towards and away from the platen, said carhon-carrier having the ends of the interleaved carbon-sheets connected thereto, and said carbon-carrier being movable rearwardl-y by a handle while thework-sheets are drawn forward to a suitable gage.

An'obejct of. facilitate the relative shifting of the carbonsheets and the work-sheets without lifting the platen; the platen remaining in the pres ent invention always in the usual typing position. To this end, the carbon-carrier 1S not mounted on a table,

but is pivotally supatthe rear of the carriage and conto travel therewith, said carbon-cara vertical position behind said carriage and being swingable rearwardly and downwardly to a substantially horizontal-position after the feed-rolls have been released to withdraw the'web around the laten to free it from said platen "and bring tiat portion of the web including ported nected the shifting ofbe pivotedon the machine frame, said the present invention is'to forward end 0 the composite the carbon-sheets to a straightened-out inchned position, in which position the leading edges of the work-sheets may readily be grasped, so that they may be shifted relatlvely to the carbon-sheets by drawing them forwardly to a suitable gage.

another object of the invention is the pro- VlSlOIl of means to retain the carbon-carrier in its operative. position, and thus prevent the forward slipping of the carbon-sheets while the work-sheets are being shifted relat vely thereto, said means being also elfectIVB to hold the carbon-carrier in its normal upr ght POSltlOIl, so as to prevent it from fall ng forwardly or rearwardly from this position accidentally. To facilitate the forward and rearward movement of the carboncarr er, provision is made of means comprising a relatively fixed handle, which may handle being effective to actuate a swinging frame or bail to which a frame supporting the carbon-carrier is slidingly connected, so thatthe carbon-carrier may travel back and forth relatively thereto with the typewriter carriage.

A knife is provided which is connected to the gage, so that it and the gage may be moved from their ineffective positions to their effective positions simultaneously either by moving the gage-bar itself or by means of a finger-piece associated with the knife. According to the present invention, slack 1s produced in the composite web when the carbon-carrier is swung up to its normalposition after a sheet-gaging andsevering operation, this slack permitting the composite web to be readily re-inserted around the platen and also eliminating any resi14-v tanceoffered to the feeding movement of the composite web around the platen during theregular line-spacing operations, thus avoiding any possibility of slippage between 1 the platen and the web during line-spacing operations.

To prevent the leading end of the composite web from slipping from the carriage, when withdrawn from the platen, provision may be made' of suitable guiding means which may comprise two guides or rollers lightly springressed, between which the web extends. The composite web between the carboncarrier and the guiding means at the rear of are rea

are-

. slack in the composite web.

Other features and advantages will here- I inafter appear.

In the accompanyin drawings, Figure 1 IS a view 1 lustrating the invention as applied-to an Underwood standard typewriter, the parts being shown in the positions occupied while typing is being efected.

Figure 2 is a view similar to Figure 1,

but showing the parts in the positions occupied when the carbon-sheets and web-plies have been withdrawn from .the platen preparatory to advancing the web-plies with reference to the interleaved carbons.

Figure 3 is a view similar to Figure 2, illustratin the gaging of the forward ends of the We -plies after being advanced with reference to the carbon-sheets, and the severing of the used portions of the web-plies.

when so advanced. 4

Figure 4 is a top viewof the machine when set as in Figure 2.

Upon depression of character-keys (not shown), type-bars 11 are swung upwardly and rearwardly to cause types 12 thereonto'strike against a platen 13 journaled by means of a platen-axle 14 in ends 15 of a platen-frame 16 comprising a rear papertable 17 and releasable rear and front feedrolls 18 and 19, respectively. The platen frame 16 forms part of a carriage 20 travelingon a rear rail 21 fixed on a main frame 22. revision may bemade of a work-holding finger 24 having at its free end a roll 25 to engage the platen adjacent the printing line.

The typing is effected upon superposed web-plies 26, usually provided with succes-.

sive printed forms, the carbon co ies on the plies back of the original being 0 tained by means of carbon-sheets 27- 'interleaved between the web-plies and attached at their rear ends to carbon-blades 28 mounted on usual stepped blocks 29 forming part of a carbon-carrier 30. When one set of forms has been typed, the web-plies and carbonsheets may be relatively displaced, the used forms severed by a knife 31 and the typing started on the next set of forms.

Accordingto the present. embodiment of the invention, the carbon-carrier is mounted upon arms 32 fixed on a shaft 33,

which, in turn, is journaled in the ends 34 of a secondary carriage 35 attached at the messes upperedges of the ends 34 to a cross-bar 36 of the carriage 20 and supported at its lower edge by flanged rolls 37 runnin on a rail 38 fixed to brackets 39 secured by suitable means, such as screws 40, to the lower part of the frame 22 atv its rear. The rolls 37 may be pivoted on a cross-bar 41 joining tne ends 34 of the secondary carriage 35, and may beheld on the rail by fingers 42 engaging the rail on its lower side.

ixed on shaft 33 is an arm 43 having" a slot 44 to receive a rod 45 joining arms 46 fixed on a transverse shaft 47. The lefthand arm 46 is extended beyond the shaft to form a lever 48 with a second arm 49, which is connected by a link 50 to a lever 51 pivoted to the frame-22 by means of a shouldered screw 52. Preferably, the lever 51 is provided'with-a handle 53 at its free end. When the handle is drawn to its forward limiting position determined by a stop or pin 54, the arms 32 extend substantially horizontally, and, as shown in Figure 2, the

position of the arms 46 is such as to hold the.

slotted arm 43 and carbon-carrier 30 firmly in their Figure 2 positions. Similarly, when the handle 53 is moved rearward to its lim iting position determined by a in or stop' 55, the arms 32 will be substantia ly verticahf as shown in Figure 1. In both of these cases the arms 46 occupy substantially deadcenter positions withreference to the arm 43. Preferably, the stops 54 and 55 are fixed in an arcuate bar 56 fixed on the frame 22 and provided with recesses 57 adjacent the.

stops to receive a tapered detent pin 58 mounted in a detent-holder 59 on lever 51 and urged by sprin 60 to enter one of said recesses 5? when rought opposite the same. a I

The arms 32 are connected near their outer ends by a member 61 whichforms thebase of the carbon-carrier 30, and by a guide or red 62 over which the weblies 26 pass from a suitable source of supp-y to the carboncarrier 30. The guide 62 may be rovided with suitable side gages 63. As s own in Figures 1 and 2, the arms 32 are provided with projecting portions 64, which support the carbon-carrier base 61 in an inclined position, such that, when the carbon-carrier is positioned as shown in Figure 2, the base 61 will be substantially in alignment with an inclined table 65, and the web-plies 26 may be drawn through the carbon-carrier and over the table '65 to pass between guide-rolls 66, journaled in brackets 67 attached to the platen-frame l6.

From the rolls 66, the web-plies and carfeed-rolls 18 and 19. Typing may then be effected, and the web-plies advanced from necting ends one line-space position to another by means and feed-rolls 18 and 19, which have preferably been cast oif, and, after the webplies have been displaced with reference to the carbon-sheets and the used portions severed, the carbon-carrier may be swung forwardly to provide slack, and typing may as hereinafter "described.

Ihe arms 32 are fixed on the shaft 33 just inside the ends 3 1 of the secondary carriage 35, and the table slightly less than the distance between the arms 32. To support the table 65, provision ma be made or brackets 7 attached to the- .en s 34-01? the secondary carriage, and, as

shown in Figures 1 and 3, these brackets 70 are provided with offsets 71 to. prevent inter-' ference with the arms 32 by the portions of the'brackets 70 adjacent the table 65.-

For gaging the web-plies when withdrawn from the platen and advanced relatively to the carbon-sheets, held in their rearward positions by the carbon-carrier 30, provision may be made of a gage 72 slidable on a guide or bar 73 and secured thereto at suitable positions b means of a set-screw 7 1. The bar 73 may mounted on a cross-bar 75 conof arms 76 pivoted on the brackets 67, and'an extension 77 of one of the arms 76 may be connected by a link 78 with one of two arms 79 carrying the knife 31 and mounted on pivots 80 in brackets 81 attached to the ends of the platen-frame,

Eachof the arms 79 is provided with a stop or pin 82, so

that when the gage-bar 73 and knife 31 are in their ineffective positions, Figure 1, the link 78 engages the stop 82 on the right-hand arm 79 and prevents furtheir movement of the gage-bar and the knife I under. the urging of a spring 83, and, when the gage-bar 73 is swung to its Figure 2 position the arms 79 come into en a ement with the pins 82. At this time the gage 'bar is substantially in alignment with the table and the knife 31 is in effective position. For convenience in shifting the gagebar 73 and the knife31, provision may be made of a finger-piece 84 on the right-hand arm 79 or the bar 73 may be moved forwardlv or rearwardly to effect such shifting.

It should be understood that the 'gage is w positioned along the gage-bar 73 at a distance from the edge of the effectively positioned knife equal to the length of one of the forms on the web-plies. In machines of this kind, the portion of the web-plies above the printing line usually lies behind the severing knife, but with the present ar- 30 may be swung reartroduced into the machine when 65 must ,be of a width rangement the web-plies pass to the front of-the knife, and "are held against falling forward from the platen by means of the roll 25 and the paper-finger 24.

In practice, the web-'plies-26 may be in the carbon carrier 30 is in its Figure 2 position, and, after the carbon-sheets 27 have been interleaved between the web plies, the composite web thus formed may be passed between the guide-rolls 66. The gage-bar 73 and knife 31 may then be shifted from their Figure 1 to their Figure 2 positions, and the leading edges of the web-plies 26 brought into engagement with the gage 72. The first set of forms is then severed by me'ans 'of the knife, and, after swinging the carbon-carrier 30 to its Figure 1 position to'produce a suitable amount of slack in the composite web, the leading end of'the composite web is passed between the platen 13 and the feed-rolls 18 and 19.

' Upon completion of the typing on the first set of forms passed around the platen, the feed-rolls 18 and 19 may be cast olt and the handle 53 is then drawn forward to swing the carbon-carrier 30 to its Figure 2 position and Withdraw the composite web from the platen. The leading ends of the web-plies 26 are then drawn forward and the gage-bar 73 and knife 31 swung to their effective positions shown in Figure 3. After gaging the leading ends of the web-plies 26 against the gage 72, the used form may be severed and the operation repeated as many times as there are sets of forms to be typed.

To assist in guiding the web from the roller 66 to the platen 13 there may be pro vided side-edge gages 85 which may be supported on the paper-table 17.
