24 claims. (omas-so) This invention relates to accounting machines and the like, but more vparticularly Ito improvements in machines of the well-known Ellis type,

such as are set out and described in Letters Pato Ellis and Patent No.'1,203,863, issued November 7, 1916 to Halcolm Ellis, and Patent No. 1,819,084 issued to Emil John Ens, August 18, 1931.

l The primary object of this invention is to produce a. machine adapted for use in banks andother business institutions, where debits` and credits are constantly being made upon individual accounts, with an accounting machine which l the other, much the same as a bookkeeper would hand-post them.

Another object is to furnish means whereby the selection of a particular totalizer` for addition, subtraction or totalizing transactions causes the total of each of the above transactions to be automatically stored in separate totalizers.

Still another object is to provide means for automatically printing subtractive items in a -5 distinctive color.

A further object is to supply means for locking the overdraft mechanism when a particular totalizer has been previously selected for addition or subtraction. f

means for the overdraft mechanism.-

Still another object is to provide means forsimultaneously unlocking the' machine starting.

oifset from other entries printed in the same column.

l A Astill further Object is to furnish means to prevent operation of the-machine for addition or subtraction when the .traveling carriage is in the balance or off-set printing position.

y Another object of the instant invention is to provide interlocks between the various totalizer controlling keys,'between said controlling keysand the machine releasing mechanism, between certain of the totalizer control keys and the overdraft keys, and between certain totalizer control` keys and the automatic tabulating mechanism. With these and incidental objects in view, the

makes such entries in logical order, one under Another object is to "provide novel non-repeat carriage so that the printing of balances vwill bev construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with rei'- erence to the drawings which accompany and 5 form part of this specification.

GENERAL DEsoaLe'rIoN The instant invention is shown incorporated in .the well known Ellis accounting machine which is fully illustrated and described in the patents referred to at the `beginning of this specification.

Y complished in the majority of such institutions by the use of accounting or bookkeeping machines. With but few exceptions these institutions use a system requiring a ledger or posting sheet for each individual account. These ledger sheets are generally the iullwidth of the traveling carriage and are .divided into a plurality of vertical columns se'veral of which are used for the listing o! checks issued against the particular account, one or more of said columns being used for the posting of deposits and another column for balancing the account.

Heretofore the practice has been to work across the ledger sheet from left to right in a horizontal line, tabulating the traveling carriage after each entry. The machine oi' the instant invention uses a ledgerl sheet divided into a plurality of vertical spaces the same as former machines, but instead of listing the itemsv horizontally across the sheet all entries are listed in vertical alinement, 4one under the other, until one columnar division is iilled. The traveling carriage is then tabulated tothe next column where en tries are made as before, and so on. This meth od of listing the different entries makes for speedier machine operation, ease in checking or verifying an account, and also renders the machine adaptable for use in department stores or similar' businesses with very little mechanical change. l

The machine of the instant invention is supplied with a tally roll mechanism mounted in dependent ofthe traveling carriage. The inking ribbon has been reilexed in such a manner as to straddle the web of the tally roll, making it possible to print positively upon the tally web and ledger sheet simultaneously. The tally web is at all times between the printing 'type and the i ledger sheet, the printing upon the ledger sheet being 'done through the tally web by means of the reiiex ribbon which eliminates the use of carbon duplicates for proof purposes. This'machine has also been equipped with an overdraft mechanism, which automatically transposes a complementary overdraft into a positive amount and prints such positive amount in a distinguishing manner.

Mechanism has been devised whereby the de pression of a-check or debit key shifts the ribbonmechanism to a position where debit items will be printed in a distinctive color. All other items are easily distinguishable `by means of vcharacteristic symbols printed` in horizontal alinement therewith.

As previously stated, the instant machine is The calculation
