TYPEWRITING MACHINE.

Application filed September 30, 1925. Serial No. 59,456.

This invention relates to fan-fold typewriting machines, and is especially useful in connection with the Underwood combined typewriting and computing machine, of the type disclosed in the application of W. F;

Helmond, No. 609,560, filed December 29, 1922 (now Patent No. 1,572,139, dated February 9, 1926), when used for certain classes of bookkeeping.

In such machine it is sometimes desired to keep in place, around the platen, a continuous record-sheet to receive carbon-copies of all the items that are typed upon forms, the forms being typed and removed one after another, and the items thereof being accumulated upon said record or copy sheet.

One of the features of this invention relates to means for rendering the device. positive, to the end of securing accuracy as well as making the device simple and inexpensive and readily applicable to standard machines.

According to this invention, the bills are printed in the manner of successive forms.

upon a ply of a fan-fold web, other plies being printed with corresponding forms for.

various purposes, and when desired the pl'ies of the web may be loose instead of fanfolded. The multiple-ply work-web is led into the machine and threaded through carbon-carriers which are usually employed in the fan-fold machine, and is then passed around the platen and up in front thereof, the platen being elevated at the completion of the typing of a form to straighten out the web, to permit the stripping. of the carbons back to the succeeding form. I

' The condensed record-sheet is laid down upon the web at the introductory side of the platen and passes between the web and the platen and up in front thereof, and during the typing of the leading form, said web and said record-sheet are line-spaced and advance together up along the work-table at' the delivery sideof the platen.

In typing the first form, the leading edge of the record-sheet preferably coincides with the leading edge of the work-web, and at the conclusion of the typing and before the straightening-out operation both the recordsheet and the work-web are advanced to the leading-edge gage, so that at this time the record-sheet may be clamped by means'of a temporary clamp, which holds it fixed during the ensuing manipulation of the platen,

the work-web and the carbons. Aft r such the platen.

When the operative is through writing the. bill, the record-sheet clampingldevice is thrown in its effective position, so that the record-sheet will be held stationary. Then the carriage is swung forwardly and the form is gaged to length, while the recordsheet remains stationary. The record-sheet is clamped upon conclusion of the typing of the form regardless of whether said'typing fills the entire bill or not. Having gaged the bill-forms to lengths, they are torn off against a knife, whereupon the carriage is restored and the record-sheet clamp is released, so as to permit the typing of the next bill-form, which is, of course, linespaced together with the record-sheet. In this manner the items typed in each successive bill-form are subsequentlycopied upon the record-sheet in a condensed form.

The record-sheet may be in the form of a long cross-folded web, and may be fed rearwardly over the top of the work-table and along a frame which overhangs the back'of the carbon-carrierrtrack-frame, so as to drop into a bin, in which it may automaticall refold itself as it is paid out of the mac Tine. Since the forward end of said delivery frame is pivoted to the top of said delivery table, the frame will fold when the table is swung forwardly at the elevation of the platen, and thus facilitate the straightening out of the record-sheet when the platen is.

again restored to its normal position.

Other features and advantages will hereinafter appear;

According to the method of handling the work in a combined typewriting and computing machine having the present invention applied thereto, a cross-folded web 10 having a plurality of plies, either loose or fanfolded, and each ply having printed forms registering with each other, is drawn up from a supply or receptacle 11 at the rear of the machine, and is led over a frame or course 12, upon which there is provided a reciprocating carbon-carrier 13. Said carbon-carrier is provided with carbon-holding blades 14 supporting the ends of carbonsheets 15 designed to interleave the plies of the web 10.

A record-sheet 16, upon which it is desired to copy the items entered on the printed forms of the web, in a condensed form, is

also drawn up from a container 17 at the rear of themachine and is laid over the web in a manner to be interleaved bythe upper carbon.

Preparatory to typing the first form of the web, the leading edge thereof is aligned with the leading edge of the record-sheet, so as to form an assembled pack which is inserted over a rear table 18 and down under a platen 19 to engage cooperating feed-rolls 20, whereupon the platen is rotated, and the assembled pack is fed upwardly past the printing point and over a front table 21. The pack is positioned so that the printing line will correspond with the first line on the printed form, whereupon a type-bar 22 may be struck by means of keys 23, to type a line, and the pack is subsequently line-spaced while the carriage is returned to its normal position to type other lines, so that at the completion of the last line on the first form the record-sheet will be line-spaced to receive the next line of typing upon the second form.

Having now ty d the last line of the leading form of t e web, and having linespaced the record-sheet preparatory to receiving the first line of typing upon the second form, it is now desired to elevate the platen in order to clear the feed-rolls, thereby permitting the stripping of the carbons. However, when stripping the carbons, it is desired to hold the record-sheet immovable around the platen, and, to this end, there is provided a clamping member eifective to grip the record-sheet upon the front table.

Said clamping member is operable by means of a handle 24, and comprises a pair of arms 25, pivotally mounted on a shaft 26, journaled in brackets 27. The arms '25 are secured to the shaft 26 by means of screws 28, which may be pointed and may engage with a groove 29 in the shaft, thus providing simple and inexpensive means whereby the arms may be positioned on the shaft to suit the width of the work-sheets. In order to increase the grip of the arms 25, they may be provided with a bent tab 30 having friction pads 31. The brackets 27 may be riveted or otherwise secured to the side plates 32 of a platen-frame, as a unit, and, besides serving as bearings for the shaft 26, they also carry studs 33 for supporting one end of springs 34, normally holding said arms in engagement with the table. The lefthand bracket 27 is also provided with a stud 35, upon which the handle 24 is pivotally mounted. The manner of operation of said handle is graphically described in Figures 2 and 7, in which the arms are respectively shown in their released and operated positions. The handle 2st is provided with a heel 36 engaging with a tooth 37 in a cam-plate 38, secured to the shaft 26. Since the arms 25 are forced into engagement with the table by means of the springs 34, it will be clear that the function of the'handle 24: is to force the arms 25 away from the table against the urge of the springs 3 1%, To this end, the handle 24 is drawn forwardly when it is desired to force the arms 25 away from the table, so that the heel 36 engages with the tooth 37 on said cam-plate 38. In order to hold the tension of the springs 34, there are provided studs 39 respectively fastened to the cam-plate 38 and to an arm 40, both being secured to the shaft 26 by means of screws 41, which may be'pointed, so as to engage with the groove 29 in said shaft 26.

Since the record-sheet 16 has been new positively gri ped upon the table 21, it is possible and esirable to elevate the platen in the regular manner, preparatory to stripping the carbons, that is to say, to present the carbons to a fresh portion of the web is released, and the platen is swung on its supporting pivots 43 to a position, as shown in Figure '6, whereupon the carbons are pushed backwardly by means of a handle 44, thus presenting the carbons to a fresh field of the'web. However, it will be understood that simultaneously with the shifting of the carbons, the leading edge of the web is gripped with one hand and is drawn forwardly to a length gage 45. Then the platen is again swung back into place to a position, as shown in Figure 8, and the web is torn off against a knife 46 in the regular manner.

As it will be well understood from the foregoing description, the record-sheet is not severed when tearing off the typed forms of the web, but is left in the machine, so as to keep a condensed record of all the items.

entered on the forms. As successive forms are typed, the length of the record-sheet is gradually increased, and therefore it is necessary to dispose of it in a manner, not only to prevent its bein in the way of the operator, but so deliver it out of the machine, and so receive it into a suitable receptacle as to facilitate the handling of the records'once taken off the machine. According to this invention, the record-sheet is led over the front table 21, as shown in Figure 2, and is passed between the gages 45, which are also used as length gages, and thence over a delivery frame 47 to, be dropped and refolded into a receiving receptacle.

Referring to Figure 4, in which the gages are shown, it will be noted that in order to permit the passage of the record-sheet, they are stepped away from the table, so as to provide a lateral guide 48 for the recordsheet. In order to permit the adjustment of the gages to suit the width of the recordsheet, the gages are mounted on the front table 21 by means of screws 49 through elongated slots 50 .in said gages, thus providing a lateral adjustment.

The delivery frame 47 is shown, in the present exemplification of the invention, as a piece of bent wire having a cross-piece 51, forming an integral 'part of side arms 52, which are bent outwardly at 53, so as to provide pivots 54, on which the frame is rockably mounted. Said pivots may be mounted upon upturned edges of the front table 21, and are held in place by means of collars 56 on each side of said edges 55. It will be noted that the side arms are placed within the side edges of the record-sheet, and in thismanner a delivery frame is provided, which, although light in weight and simple in structure, is, nevertheless,- efiicient in its performance. As shown in Figure 1, the rear end of the frame 47 is normally positioned more than onehalf of a length, front to rear, of a crossfold of the record-sheet to the rear of the plates 58' and over two lengths above the take-up work-pack disposed in the rear of the container 17. This arrangement keeps the refolding portion of the record-sheet clear of the entering portion, and also guards against the take-up ,work-pack bemg disarranged upon moving the frame 47 forward.

As hereinbefore stated, the delivery frame is designed to be folded upon the course, when the platen is elevated, as shown in Figure 6, thus facilitating the movement of the record-sheet during the platen-elevating operation, the record-sheet being swung idly first forwardly and then ba'ckwardly to its normal position.

Since the record-sheet is made considerably wider than the web, novel means are provided at the introductory side of the webcourse for laterally guiding both the web and the record-sheet. Said means may include a pair of ages 57, having flat plates 58 at the. top or supporting the recordsheet, the gages being also effective to locate the web. The record-sheet being the wider, may be guided in the regular manner between side' gages 59, slidably mounted upon a rear rod 60. In order to protect the entering record-sheet, which maybe damagedby the delivery frame when elevating the platen, there may be provided a second cross-rod 61 mounted on the gages 59, thus providinga support for said frame.

No claim is herein made to any features disclosed in the senior application of Jesse A. B. Smith, Serial No. 38,958, filed June 23, 1925. This invention is in the nature of an improvement u on the invention disclosed in said Smit application.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I
