This invention relatesto typewriting machines for V manifolding multiple-ply webs, and more particularlyto means for'readily varying and selecting the number of plies to t be manifolded. v I

the webs in connection with interleaved carbon-sheets attached It is customary to use copies has not heretofore been readily varied.

According to the present invention, it is practicable to manifoldall five superposed copies of one web-form, and only one ply of the'second fan-fold web.

One feature of this invention is the use of means whereby one or more extra plies can easily and quickly be selected and positioned for manifolding. v

Another feature is that when the requisite number of desired additional copies has been selected and positioned for manifolding, any remaining forms in the machine'can be readily stowed. At the same time there will be maintained an advantageous fixed relation between the unused forms and their carbon-- sheets. This insures'that when finally used,-

the Carbon-sheets will assume the proper positions. Means is also provided whereby all of the extra forms with their carbons can be held together. While so held, they can with their supporting members be removed as a unitfrom the machlne, and without disarran'gea mentbe again replaced.

"Another feature is the avoidance of the necessity of counting any required number of plies that it may be desired to manifold.

This time-saving 'featureinclude's a set of selective indicating tabs. These are separately mounted on the blades of the'carbgnstripper, and may be permanently attached thereto. The blades, with the tabs and carbeyond the side of the web, and also extend forwardly one beyond the other in overlying,

stepped-back positions. Such positioning of acters, ornumbers to constitute a series. The numbers will indicate that below a certain tab lies the same number of plies/as is shown by the numeral onthetab. Such numbers are used as will include the number of worksheets, in both the lower and upper work- I .g,

Other-features and advantages will hereinafter appear.

Figureb is a fragmentary perspective of an upper carbon-earner, showing the 1116.1

eating tabs inte'rleavedwith carbons and loose plies, some having been thrown: back over a table and clamped.

A platen 10, on an axle 11, witha cut-off knife 12, and a front paper-tableand end gage 13 arecarried by a displaceable platenframe 14:, which is pivotally mounted on stubshafts 15, attached to the usual carriage.

Also pivotally mounted on the stub-shafts 15 are wide pinions 16, which are enmeshed with gears 17 fixed to the platen-axle 11. The pinions 16. are also in mesh with gears 18 which are fixed on stub-shafts 19, journaled in the carriage-frame, and which shafts also carry platen-turning knobs. By such well-known means the platen can be rotated, and its integral parts can be swung upward and 'for ward as shown in Figure 1. The lower or printing position of the platen is shown by Figure 2. In connection with the platen are feed-rolls 20, a type-bar 21, a rear papertable 22, and a rest 23, as are usual.

Attached to rear portions 24 of themain Thesaid shelf 33 has holes therein to reg is} ter with 'tlie, rantings, rom which it readily be lifted. Carried on the shelf 33,

fand attached thereto, is a carbon-carrier 34. v

on the carbon- carriers 32 and 34 are respectively attached as required, the carbon- holding blades 35 and 36. To each blade are attachedacarbon-sheet 37 andan indicating tab 38, as shown in Figures 3 and 4. Interleaved with the carbon-holders 35 is a multiple-ply web work-form 39. Interleaved with thecarbon-holders 36 is a loose-plyweb-form 40. Attached to the carbon-carriers'32 and 34 are adjustable side guides 41.

' Mounted at each end of the shelf 33 are supports 42, having their upperends bent to form platforms 43, which engage thumbscrews 44, formed with shoulders. The platforms 43 carry a cross-bar45, having cut-outs 46 nearits ends. These cut-outs permit a ready lateral removal or replacement of the cross-bar and superposed members, as the cross-bar may be released or held by the thumb-screws 44. Thecross-bar has a raised portion as shown, so the edges of overlying members may be easily grasped. The

raised portion of cross-bar 45 engages set screws 47, that'in turn engage countersunk slots 48, of a slidably mounted collation table or tables 49, having anedge bent up as at 50 to form a guide. Attached to the collation table 49 is any suitable clamp 51, spring-controlled to press down or remainup, and having an actuating finger-piece 52. Also shown is a hand-lever 53 attached to the supplemental carriage, and for reciprocating the latter.

In operation, a fan-fold web 39 is led into the rear of and passed forwardly through V and beyond a truck 29, until the leading ends are brought to register with the platen. Concurrently, the leading ends of the interleaved lower carbons 37 are brought to'the same position, as shown by Figure 1. The platenframe 14 is then swung rearwardly and down to the printing position shown in Figure 2, where typing operations ensue. During the typing, the line-spacing mechanism gives a stcp-by-step advancement to the truck 29, through the pull of the attached carbons. When the typing on one web-section is completed, the platen is thrown forward to a re-.

'leasing position, and the web is drawn forward to abut the end gage 13. Through rearward actuation of the hand-lever 53, the carbons are stripped back by their carrier 32, while the web-plies remain stationary,until the truck abuts the stop 28. This positions the carbons for an ensuing typing operation. The platen is again swung to a printing position, and the then typed portion of the workweb may be torn off along the edge of the knife 12, as shown by the dot and-dash lines in Figure 2. Such cycle of intermittent operations can be repeated until all of the fanfold web-sections have been typed. For supplying additional copies, a second loose-ply web 40'is used,which may be formprinted or plain, and one or more of its plies with tabs and interleaved carbons may be employed and stripped as required. The number is selected by the use of tabs 38. These extra copies are manifolded with the fan-fold web-form 39, which they underlie on the platen, Figure 1. In manifolding the extra loose-plycopy or copies, the same complete cycle of typing and stripping operations is-concomitantly carried through as is used for the fan-fold web. An additional factor is the rearward stripping of the indicating tabs, concurrently with the stripping of theirassociated carbons. The tabs and carbons are stripped while the webs remain stationary. The tabs are not torn ofi, as a they are too short to reach the platen or the printing field. Theyinterleave the web at a point back of thexform that is being typed, and do not spoil the appearance of the characters on the carbon-copies. The tabs are attached at their rear ends to the blades, and eX- tend forwardly toward the platen, but are too short to reach the printing-field.

The length of a form is seen at Figure .1, the front end of the typed form being drawn'. forward to the usual cutting-off gage, and the rear end being at the tear-elf knife 12. The tabs do not engage a form that is being typed.

In manifolding extra copies it sometimes happens that a lesser number may be required than have been previously typed. For example, three loose leaf plies might be in position for typing, when it is found that an ensuing operation requires but two. In this case after tearing off the typed sheets, it becomes necessary to again release the platen and retract the unwanted ply to an untypeable position. After suchretraction the platen is once more swung to typing position and the manifolding can be proceeded with. The ply retracted would always be the one on top of the pack which was'being man ifolded. During the latter operation, all the unused loose plies with their carbons and tabs are laid backward over the collation table 49, where they are held by the clamp 51. For such usage, the table 49,is preferably inclined as shown in Figures 1 and 5. Such inclina tion facilitates the handling and reading of' loose plies and tabs by an operator seated in front of the typingmachine. For properly positioning both web-forms on the platen, marginal guides 41 are used. v

Other advantages also accrue by the use of said cross-bar, collation table, and clamp. The upturned edge 50, of the table 49, ma1ntains a proper marginal relation between the 5 loose plies, their carbons, and the indicating tabs. Thus any numerals or characters on the tabs will not be obscured by overlapping edges of the loose plies or carbons. Also, should there at any time be no loose-ply web 40 in the manifolding machine, the table and clamp form a handy storage unit for the carbon-sheets and tabs. Here they are held in aligned readiness until needed, and cannot be inadvertently drawn forward by an advancing lower web-form 39. Furthermore, the table 49, through its cross-bar cut-outs and thumb-screws can readily be removed for the easier placement of the carbon-holding blades 36. Finally, the shelf 33, with its superposed members, may easily be removed from the standards 31, and thus facilitate the placement and interleaving of the lower fan-fold web 39.

When desirable to manifold extra copies, and the fan-fold web, for instance, has three work-sheets, the following procedure is used. If one extra copy is required, all the loose plies above the numeral 4: are folded back over the collation table and clamped. This leaves four work-sheets, with their carbons, all

ready for manifolding. In this instance the numeral 4 is so placed when interleaved as to include below, the three sheets of the fanfold web and one sheet of the loose-ply web,

that is, three plus one equals four. The tabs can be supplied in several series if desired, wherein one series could be marked as lastmentioned. Another series could be marked, for instance, five plus one equals six, in which the numeral 5 would be a key-number always indicating the use of a lower or fan-fold web having five plies.

The aforementioned indicating tabs can be made of any thin, flexible, and otherwise suitable material that will readily fold back with their companionate plies and carbon-sheets. The tabs can be marked on one or both sides, and such markings can be within the margin of the tab, or on an integral or separate piece projecting beyond the margin. From the above description it is obvious that the use of indicating tabs can also be readily and advantageously adapted to any manifolding machine using but one multipleweb unit.

Variations may be resorted towithin the scope of the invention, and portions of the improvements may be used without others.
