To all whom it may concern:

Be it known that I, JOSEPH C. HARVEY, a

' citizen of the United States, residing in Chithe; individual ledger or other record sheet 1s nois, have invented certain new and useful Improvements in Type-Writing .Machines, of which the following is aspecification."

This invention relates to means for. 10- cating two or more sheets in a typewriting machine, and making duplicate typewritten impressions thereon, and is particularly use- .ful in bookkeeping operations, where 'an entry is made simultaneously on a ledger sheet and a statement; and it is also useful in billing operations and the like, as for instance where it is. desired to make upon a journal or other record sheet duplicates of the individual' entries madeupon a number of bills, statements or other individual sheets.

According to one feature of my'inventicn',

assembled in the'machine with an interleaving ink strip, which may be of the same material as an ordinary inking ribbon, but which-is retained mechanically in the machine for repeated use, thus avoiding thenecessity of using carbon sheets and also gaming the advantage of making a permanent or record copy. A further advantage 1s gained in connection with this inkin, strip,

inasmuch as it is madeto disappear a ter the entries are typewritten, s0 that when the .statementis withdrawn, theoperator caninspect the entry made. on the record sheet which is retained in the machine, and may correct the same or ire-adjust the sheet, or, in

the, case of condensed billing, may advance .the sheet to give. the required space between successive entries on the record'sheet. :This ink strip is preferably formed upon the forwardborder bf a web, which at ts rear end is'connectedby a spring device to the typewriter, for the purpose'ofretnrnlng the ink strip to normal position, or causing it to disappear. The sheets-and strip are all fed forwardly bythe usual feed roll runn1n,g; upon the platen, and when said 'feed roll is re? leased and the statement is withdrawn, the

strip is automatically returned by means of said spring. 7

According to'another feature of the mvention, one of the work sheets, usually the ledger sheet, is laid upon a special work table which -is. arranged behind the platen in front of the usual paper shelf, and a pres- Specification of Letters Patent.

Fig.5 is arear view of the auxiliary work table, showing the ink strip web as having been drawn down asthe work sheets have been fed up" around the front ofthe platen. F ig. 6 is a diagram to illustrate two rolls for advancing the'record sheet to the platen and feedit'around the same; both the special feed'r'ollsbeing out Patented Sept. "3, 1915.

.of contact with the platen. Fig. 71is a diagram to illustrate the method of introducing the-ledger or other record sheetinto' the machine; the leading edge of the sheet being shown as resting upon the crownof the special feed roll. Fig. 8 is a diagram to illus trate the manner in which the record sheet is'fed around by revolving the platen until its frontedge emerges above the front scale. Fig. 9;is a view like Fig. 3, but showing the writtenstatement as being partly inthe machine. Fig. 10 is a diagram to show the sheets with the intervening ink strip as having been advanoed by rotating the platen, to bring them topo'sition to begin thefirstline of writing. Fig-11 is a diagram to showthe introduction of the individual sheet after the record sheet has been introduced.

The cylindrical platen 1 is mounted by I itsaxle 2 in the ends'3, 4: of a .platen frame, which are connected by a paper shelf5, ex-

tendingdownwardly and forwardly to the" platen upon the introductory side thereof.

Rods 6 and 7 also rigidly connect the platen frame ends. A guiding apron 8 usually curves forwardly from the lower end of the ing operations, is to remain in the machine and receive all the typewritten items which appear uponthe bills, statements or individual work-sheets, is laid uponja supplemental work table or shelf 12, which may incline downwardly and forwardly with its lower end near the platen 1. This sheetis carried around under the platen and up in front thereof, and adjusted in respect to the printing line by means of the usual scales 13.

The "bill, statement or other individual work-sheet 14: is laid upon the paper shelf 5, and guided around the platen and ad justed to the scales 13. The usual roll 15 on the underside of the platen is used to feed the. sheets forwardly after they are inserted; but is cast off while they are being introduced.

. Between therecord or-general work-sheet 11 and the individualsheet 14., lies an inking strip 16, which enables the type to make impressions on the under sheet 11 corresponding to the typed impressions 'on the outer sheet 14. This inking strip normally occupies the position seen at Fig. 2, with its advance edge flush with or below the edges of the scales '13, so as not to interfere with the adjustment of the work-sheets 11 and 14'to said scales.

Thelength of the inking strip is equal to or greater than the length of the line of: writing upon the work-sheets. This inking 'strip remains in the'machine', being adapted to feed up with the work-sheets as the latter are'written lineby line, [and then returning to the normal Fig. 2 position, thus disclosing the writing on the record sheet 11, and also permitting the latter to be readjusted if required.

The inking strip 16' is flexible, and is connected by a flexible web 17 to a returning device, which may be in the form of a lever 18, pivoted at 19 upon the rear side of table 12, and having a spring'20 which tends constantly to return the flexible web 17 and its'ink strip 16 to normal position. The

;lever 18 is connected by a link 21 to a metal- --lic binding strip 22 provided upon the flexible web 17, and preferably extending for some distance along the opposite edges thereof, as at 23. The normal position of the ink strip is determined by stops 24,

against which the binding strip 22 is held by means of the spring 20, Fig. 2.

The record sheet 11 is first inserted in the machine, Fig. 7, with its bottom edge resting uponthe auxiliary roll or rolls 25, which are mounted by Ineans of an axle 26 in ears 27 pendent from the sides of auxil iary work table 12. The sides of said table are bent up to form opposite gages 28, and

these are preferably spaced so that the work sheet 11 fits loosely between them, so as to be gaged by one or both thereof. The leading edge of a sheet catches momentarily upon the crown of roll 25, but the lower edge of the auxiliary table 12 is bent forwardly at29, Fig. 4, to prevent the sheet catching too far back on roll 25 to form a deflector. By rotating the platen by means of the usual knob 30, the sheet-11 is led or dropped between the roll 25 and-the platen.

It will be understood that the advance edge of 'the'work sheet 11 maybe gaged or straightened by resting upon roll 25, but if said sheet should be. a little askeW' at that time, it will be found to right itself while it is dropping off the roll and into the bight of the roll 15 and the platen 1; so that the side edges of the sheet will be parallel with the side gages 28. The sheet is pressed by said roll against the platen and fed forwardly down around and up in front of the platen, 8, between the latter and the lllklllg strip 16. During this operation, roll 15 running upon the under side of the platen, is cast off.

Preferably the necessary pressure of the feed roll 25 against the platen is effected by the weight of the auxiliary table 12, which may'have at its sides hooks 31 to pivot upon the rods 6; the weight of the shelf with its" appurtenances being back of the pivot rod 6, thus causing the roll 25 (which @is beneath 'said rod) to swing forwardly against the platen. To release roll 25, it 1s onlytnecessary to swing shelf 12 forwardly. It is noted that the hooks 31 per mit the shelf 12 to be readily detached from the machine-when it is desired to use the .same for other work.

-When the operator has advanced the sheet 11 far enough, he may adjust it to the print ing line by means of scales 13; the inking strip 16 not hindering this operation, as it does. not at this time project above said scales 13, Fig. 8. The operator then inserts the individual work-sheet 14, Fig. 11, the same passing freely down around under the platen and up in front thereof (the roll 15 being still cast off), and adjusts the sheet to the scales 13. The operatorthen lifts the key 31, and restores the roll 15. He then advances the platen the distance of one or more line-spaces, either by means of the strip 16, so that they willall project above the scales 13, Fig. 10. The record sheet 11-- may project farther than the other two.

- The operator then writes the line by means this manner.

'of the usual types 10, Fig. 3, and in some cases, he may write several lines, advancing the platen by means of said line-space mech anism, together-with said work- sheets 11 and 14, and ink strip 16;'the spring 20 yielding to permit the ink strip 16 to be advanced in It will be understood that the roll 15'is effective to feed the strip 16 as well as the sheets. Having completed the entry upon the statement, the operator depresses the key 31 to cast off the roll 15, and then draws the individual sheet 14 forwardly to remove it from the machine. The.

tensionof spring 20 is very light, so that the upward pressure of the usual yielding apron 8, under the platen, is suflicient to detain the flexible web 17 while said sheet 14 is being drawn out, ('Fig. 9,) until the latter is nearly or quite withdrawn from the platen. This releases web 17, and the spring 20 returns the-latter and strip 16 to normal Fig. 2 position. The record sheet 11, of course, is not disturbed'while the individual sheet 14 is being withdrawn, nor while the ink strip .16 is retracted; The operator now inserts a fresh sheet 14 and adjusts it to the printing line as befdre.

the forward portion ofthe flexible-web 17,

which may consist of cloth similar to that of which typewriter ink ribbons are made. The cloth needs to be inked only on one side; andthe other side thereof may have jan' impermeable coating 33, as indicated at Fig.- 1 so as n t to offset on the rear face of the front work-sheet14.

It will be understood that the retraction or disappearance of the 'ink strip l6 exposes the type impressions on the sheet 11,

so that the operator can examine the same and correct them if necessary,-and may also advance the sheet by turning the-knob 30 so as to leave any required amount of space between successive entries on the record sheet 11; or he may further adjust said sheet to bring any desired ruled line thereon to register with the scales 13.

Having adjusted the fresh sheet 14, the operator restores the feed roll 15, and proceeds to typewrite the new entry, which is and leaves are properly filed, and when the of course written in the desired ,place upon the new sheet, and also appears in proper location beneath the previous entry on the record sheet 11. Thus the insertion and withdrawal of the sheets 14 proceeds untilthe sheet 11 is filled; whereupon'a, fresh record sheet 11 is inserted, and the operation contlnues- Instead'of having the rol l -25- run upon the platen; it' may cooperate with another roll 34, Fig. 6, to feed thefsheets' 11 to .the platen and forwardly around the same while the latter remains stationary, the roll 25 being provided for this purpose with a fingerwheel 35. These rolls 25 and 34-may rotate 8 idly when sheet l1 is being drawn forward by the cotipera-tionof the platen 1 with the bottom roll 15. j I

While the improvements have been de-. scribed in connection with the operation of condensed billing, it will be understood that, a use of .the machine which is of equal or greater value, is its use for bookkeeping purposes. In this connection the record sheet is usually a loose leaf of a ledger; and the individual sheet is. a statement of 'account, In using the invention for this purpose, the operator, after withdrawing the. individual sheet, also withdraws the-recordsheet 11, since the latter bears at its top the name of a single customer, and only that customers items are entered thereon. After the various items areentered on the several statements and ledger leaves, both statements next transaction occurs with any customer, his statement and ledger leaf are selected and the item entered thereon, where ponf they are re-filed in their original places; Thus the ledger sheet constantly shows the condition'of the customers account, while the statement is added to day by day, so that at the end of the month it is all. ready for mailing'without further labor.

One of the great advantages-of the 'pres-- n ent invention is that it facilitates'the intro duction of the ledger sheet and the adjustment thereof to the printing line without] being obscured by a carbon or other inking device, such as usually covers the face of the record sheet in condensed billing and other operations. The operator may not only, easily see the last line of writing on the ledger sheet, but may quickly adjust the same to the printing line by means of the usual front scales13. Thus it will be seen that the sheets may be easily inserted independently of each other and each properly adjusted to the printing line independently of the position occupied by the other, while each may be quickly-withdrawn when the roll 15 is cast off and thus the operation of bookkeeping is greatly simplified and facilitated, particularly where the -amounts are added by means of a computing attachment are not quite so clearas those on the outer sheet; and it is therefore optional whether the statement or the ledger sheet shall receive the clearer impressions- I Variations may be resortedto within the scope of the invention, and portions of the improvements may be used without others. Having thusdescribed my invention, I
