BOOK-SHEET.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed March 29, 1912. Serial No. 687,186.

erence being hadto the accompanying draw ings, forming part of this specification, in which- Figure 1 is a perspective view of my invention unfolded. Fig. 2 is a view of my invention in folded position. Fig. 3 is an illustration of detached sheets used in connection with my invention.

My invention relates broadly to station: cry and specifically to an improved form of book sheet designed particularly for use in loose-leaf bindings.

The principal object of my invention is to provide a book sheet of such form and construotion-as to materially reduce the amount of work necessary in preparing invoices, statements, and ledger entries. and taking trial balances. I

A further object of my invention is to produce a book sheet which is particularly adapted for use in billing machines.

My invention contemplates the use of a sheet of suitable material cut in any desired form or proportions and divided into three sections, A, B, and C, by means of two lines of perforation 1 and 2. The first section, A, which is designed as the account sheet may be provided with suitable entry columns, A 1, A 2, and A 3 which as illustrated may be used as debit, credit, and trial balance columns respectively. The trial balance column A 3 is nearest the dividing line of perforations 1, and is equal in width to the section O. The second section, B, is provided on the reverse side with entry columns B 1 and B 2 of equal width respec tively with columns A l and A 2. When folded along the perforate line 1 the third section, 0, coincides. with column A 3, column B 2 with column A 2 and column B 1 with column A 1. A suitable carbon or transfer sheet 4 is inserted between the sections A and. B. As thus folded the sheet may be filed in any desired loose-leaf bind-' of suitable perforations 3, or

ing by means of section A similar means on the free end which extends beyond the free end of section B. Suitable free sheets D and D 1 are provided, having the same dimensions as section B and a carbon sheet is used in connection therewith.

This device is designed .particularly for use in billing machines in the following fashion: When an account is opened by purchaser, an invoice sheet D is placed upon the sheet B with the carbon 5 therebetween, which sheet B, as above described,

lies over sheet A with the carbon 4 between i the two. In this position the sheets are inserted in the machine and the heading written in as illustrated,together with the item, which is indicated in the illustration as the March 1 item. After entering the amount of the item in the debit column, the amount is also entered on the section C which extends beyond the end of the invoice sheet. After the entry of the items purchased on this date, the folded sheet may be filed in the ledger and the invoice forwarded to the purchaser. Upon a subsequent purchase the folded sheet is removed from the ledger, another invoice sheet D 1 applied thereto and inserted in the machine as above described. As the line spacing mechanism in billing machines produces uniform spacing, the sheet may be positioned in the machine so that the printing line will fall below the line of the March l-entry. The second item here illustrated as the March 10 item may then be written in and the amount entered in the debit column. The amount of this second item is then added to the next prior amount appearing on section C and the total of the two entered on section C. Subsequent entries are made in the same fashion. Credit items may be entered in the same fashion as is illustrated with the March 12 item. In this fashion it will be seen that all items entered individually upon successive invoice sheets may be simultaneously entered upon sheet B and the ledger sheet A. When it is desired to send a complete statement, sheet B is simply detached along the line of perforation 2 and as it contains the record of all debits and credits it forms a complete statement.

is desired, section 0 is detached from sheet A and forms a memorandum slip to be used in connection with similar slipsfrom other accounts in striking the trial balance.

From the foregoing description, it will be seen that my invention provides a convenient and easily manipulated device for the purpose described which materially decreases the amount of labor and number of entries required in the preparation of invoices, statements, ledger ventries, and trial balances. 4

While I have shown but one form,'it is obvious that my invention is not confined to the particular uses described.

What I claim is:

1. An account book sheet comprising a binding sheet arranged for attachment at one margin and having three columns at the end opposite said margin, to the extremity of which end is detachably secured a statement sheet, said statement sheet having three columns which are disposed so as to register with those of the binding sheet when the statement sheet is folded back over the binding sheet, so that impressions made on the statement sheet can be made in the corresponding colunms of the binding sheet through the medium of an interposed carbon sheet, the outermost column two columns adapted to register over the two innermost columns on the binding sheet so that typewriting impressions maybe made simultaneously in corresponding columns of both sheets through the medium of an interposed carbon sheet, and an invoice sheet arranged it'or association with the statement sheet in such fashion as to leave the intermediate section projecting beyond the margin of the invoice sheet for the purpose described.

In testimony whereof I hereunto aifix my signature in the presence of two Witnesses,

this 11th day of March, 1912.
