1 Claim.

This invention relates to continuous paper forms such as are used in connection with printing mechanisms of'tabulating machines and the like and has for its object the provision of a novel carrier or conveyor for ledger cards whereby said cards are successively and automatically presented at a printing station each there to receive a data registration on a predetermined portion thereof according to the relative positions of the cards on the carrier.

Heretofore, it has been the general practice where data are desired to be printed directly on ledger cards to insert said cards manually one at a time between the platen and the type elements of a printing mechanism. This operation requires a great amount of supervision and care on the part of the operator to prevent errors in the locating of the printed data.

In accordance with the present invention, this condition is remedied by the provision whereby ledger cards are manually attached to a con veyor, such as a long paper sheet, so that when the sheet is fed into the printing mechanism the cards are successively presented at the printing line thereof. A paper feeding device such as the well known Carroll carriage shown in U. S. Patent No. 2,066,305, dated December 29, 1936, may be used to advance the sheet a predetermined distance or line byline after each printing operation and also to advance the sheet a multiple line distance after a series of printing operations. The portion of each card which is to receive printed data is determined by the location of the card on the sheet. A plurality of numerically designated spaced lines on the sheet form a chart by which the card can be quickly positioned in relation to the sheet so that the printed data may be received on the desired portion of the card. The cards, after receiving the printed data, may then be easily removed from the sheet and placed in the office files. These same cards may be removed from the files at any later time and located on the sheet in a different relative position so that another portion of the card will receive further printed data.

The advantages of card filing systems over systems wherein the records are kept on paper sheets have become well recognized in the busi ness world. Cards are firmer and more durable and therefore need not be put in binders as are paper sheets. They may also be provided with classifying extensions so as to indicate the class or group to which they belong. Another and probably the most important advantage is that they may be used over and over again as dein any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawings whether within or without the scope of the appended claim and irrespective of other specific statements as to the scope of the invention contained herein.

In the drawings:

Fig. 1 is a view showing a portion of the conveyor sheet with two typical ledger cards mounted thereon.

Fig. 2 is a view of a portion of the sheet by itself. I

Fig. 3 is an enlarged view of the ledger card.

Fig. 4 is a side elevation partly in section of a printing means and illustrates diagrammatically a paper feeding device associated therewith.

It is understood that the carrier sheet and the ledger cards carried'thereby may be fed by any printing mechanism shown there is to bring a type bar 25 into position relatively to a platen 26 so that the proper type element 21 is opposite the platen. A carrier sheet P is fed over andthrough suitable paper guides such as 28 and 29, respectively, and around the platen 26 so as to pass between the platen and the type bars 25.

As is usual in tabulating machines, perforated records (not shown) are run through the machine in groups, and items represented by the perforations thereon may be listed and totals printed at the end of each group; or the items may be tabulated and merely the group totals printed. To effect the listing of items on the sheet P or on ledger cards to be carried thereby in a manner explained hereinafter, listing shaft 30 is operated-'by a motor (not shown). A cam 32 is mounted on the shaft 30 and cooperates with a roller 33 carried by an arm 34 operatively connected to a shaft 35. As-the cam 32 rotates, shaft 351s rocked in a clockwise direction and an arm 36 secured thereto and linked at its free end to a printing crosshead 31 serves to raise the type bars in synchronism with the movement of the perforated records so that the type elements 21 successively pass the printing position opposite platen 26. The type bar 25 is arrested under control of printing magnet PM, which, when energized, attracts its armature 40 and through a call wire 4| releases the latch member 42, normally holding stop pawl 43. When the pawl is so released, it is spring operated to engage the ratchet teeth 44 formed on the type bar 25 to prevent further upward movement of the type bar, thus holding a particular type 21 in printing position. The usual ham-'- mers 29 are provided to impel the ty against the platen.

During total ta king cycles the shaft 3| is operated by another motor (not shown). A cam 45 on this shaft co-operates with an arm 46 on shaft 35 to lift the type bars 25 in synchronism with the operation of total readout mechanism (not shown). Printing magnets PM are energized at differential times to effect the stopping of the type bars in the proper printing position in the same manner as previously described.

As for the paper feeding device, it is noted that the platen 5| is mounted on the carriage unit which in turn is supported onthe frame 52 in position adjacent the type bars 25. A'casting, generally designated 53, forms a support for the carriage parts including a. drive motor (not shown). The motor is clutched in at the proper times to rotate a platen drive gear 54. 54 rotates, it drives idler 'gear 55 and therefore, also clutch gear 56. The clutch gear 56 is loose- 1y mounted on the platen shaft 51 but is adapted to be clutched in to drive the latter shaft atv the proper times. The rotation of shaft 51, and hence of the platen 26, causes the feeding of the paper. Pins 28 may be provided on the platen to insure more positive feeding of the paper. The pins mesh with the rows of holes l9 (Fig. 2) in the paper. The device is settable for a predetermined length of sheet feed so that where the paper is in effect a continuous series of similar forms, the paper will be fed froma selected printing line on one form to a corresponding printing line on the succeeding form. Also, normal line-.to-line feeding is provided for when listing. The normal action of the feeding device is to space the listed items in the usual manner until a total is printed and then automatigially to feed the next form into printing posi- Referring now to Fig. 2, it is. noted that the sheet P is provided with spaced lines 20 running parallel across the width of the sheet. On the left-hand side of the sheet are obliquely running slits 2| and 2|a and on the right-hand side of the sheet are longer slits 22 and 22a each of the latter lying along one of the, horizontal lines 20. Immediately to'the right of slits .22 and 22a is an indicating arrow A. The printing spaces immediately above the arrow and between the slits 22 are numbered, in this particular case, from 2 to H inclusive. Arrow A occupies the initial printing space and. it is assumed for purposes bf illustration that. provision is made for a total of fourteen different printing spaces, as indicated-by the numbering.

As gear The card C may be of any convenient shape or size and not necessarily limited to that form disclosed in the drawings. The headings and markings thereon, as shown in Figs. 1 and 3, are

merely for illustration. Parallel lines 20a on 5 the card correspond to the horizontal lines 20 on sheet P, being spaced apart the same amount. Fourteen printing spaces are divided off on the card shown in the drawings, this corresponding with the number of printing spaces laid off 0h 10 the sheet. It will be noted that the left-hand upper and lower corners of the card are square but that the right-hand upper and lower edges are beveled. Cut-cut portions 23 and 23a, lo-

cated near the right end of the card, and the 15 beveled edges of the card form tabs 24 and 240., respectively, which are used in holding the card to the sheet.

In attaching the card to the sheet, as shown in Fig. 1, it is necessary to locate the card in such 20 a manner that the space in which the data are to be printed is aligned with the indicating arrow A. The upper left-hand corner of the card is fitted in one of the slits- 2| and the lower left-hand corner isgfltted in the corresponding slit 2|a. 35

Concurrently, tabs 24 and 24a are inserted in. slits 22 and 220. which are located opposite the already filled slits 2| and 2|a so that the card is firmly held by the sheet in a position wherein lines 200. on the card coincide with lines 20 of the so sheet and the desired printingspace on, the card is correctly aligned with the arrow A on the sheet. The beveled edges on the tabs 24 and 24a. provide a wedging effect which securely fixes the location of the card on the sheet and also tends to keep it from buckling out from the sheet during the normal paper feeding operation.

After other cards have been attached to the sheet in the manner'described above, the sheet is advanced manually until an indicating arrow A becomes aligned with the printing line of the print mechanism already described. It might be well to mention here that the automatic feeding device has been preset to give a feed stroke equal 45 to .the distance between the arrows A. The 00-,

currence of the printing of data on the card in the space aligned with the arrow is followed by a feed stroke to advance the sheet until the next arrow A comes up to the printing line and, 9

therefore, untfl the succeeding card is conveyed to the printing position with respect to the platen 26 and the type 21 and is ready toreceive printed data in the proper space thereon.

The cards C shown in Fig. 1 have the name 55 of the firm and the headings of the various columns thereon. The upper card has been used before as is evidenced by the fact that printing spaces 4 and 5 contain printed data. Consequently, when this card is inserted, the next Although the description just presented tppears to adapt the carrier sheet with ledger cards more for conditions where oneitem or one total is to be received by each card immediately followed by a feeding stroke to the next card, it is to beremembered that the listing of spaced items on the cards may be also accomplished, in which case the indicating arrow A represents the first.

space on each card in which printing is to occur.

The feed stroke generally occurs automaticallyafter a group total of the listed items has been printed on the card.

' It is obvious thatprinted data also may be re-. ceived by sheet P along with the printing on the ledger cards if two ,sets of statistical reports are desired. For example, the listed items may be received by the sheet and the totals on the cards or vice versa. In any event the first printing line on each card is predetermined by its relative location on the sheet. 1

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the following claim. What is claimed is: A continuous feed sheet for record cards having a. plurality of card locating sections and including, in each'section, a chart comprising indexing means representing a plurality of line positions, apluraiity of groups of slits co-related with said line positions, each group being adapted to interfit with predetermined portions of a record card removably insertible therein to hold a the record cardfirmly against the surface of the sheet in a selected one of the aforesaid line positions as represented by the indexing means, said card, when so held by the sheet, being incapable of relative movement laterally with respect to the surface of said sheet.
