i Application filed March 5, 1907. l Serial No. 360,745.

To @Il whom it may concern:

Be it known that I, CHARLES H. HERZOG',

a citizen of the United States, residing at Kingston,` in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Calculating-Machines, of which the following is a specification.

In a coepending application for Letters Patent of the United States Serial N o. 335,357, filed September 20, 1906, by Charles N. McFarland, there is described and shown a device whereby, on the well known Wales adding and listing machine, the function of the accumulating mechanism may temporarily be interrupted without at the same time suspending the function of the remain` ing mechanism -of the machine, so that an item may be printed on the paper strip on which the accumulated items are recorded without inlcluding it in such series of items or adding 'it into the total when these items are totalized. Using the machine in the manner described in said cri-pending application', ithas been found that confusion is apt to result between those items on the record which forni part of the enumerated series to be totalized and those which form part of the second series which are not to be totalized.

The purpose of my invention is to avoid this confusion by printing the items which are not to beftotalized in a different colored ink from that in ,which the accumulated items are printed so that there will be no diiiiculty in distinguishing them. I accomlish this purpose by the construction hereinafter described which is so arranged that when the elimination key which interrupts the function of the accumulating mechanism is depressed, the inking ribbon is automatically and merely as an incident of the depression of suoli key., so moved that there is presented to the point of print a diiferently colored inking ribbon or a differently colored strip of the saine inking ribbon. As it is more convenient, in the normal o eration of the machine, to use black inking ribbons, I so arrange t-he parts that the items to beaccumulated are printed in black and in order to afford a striking contrast between these items and those of the nonaccumulated series I print the latter in red and make the inking ribbon of two parts viz: one black strip and one red strip.

In the drawings, Figure l is a side elevation and partial vertical section on the plane of the line 1 1 in Fig. 2 of that portion of an adding machine of the type described embodying my invention; Fig. 2 is an enlarged top plan view of the inking ribbon frame and. lifter, Fig. 8 is a rear elevation thereof and Fig. 4 is a side elevation of the saine.

In the drawings, 1 is the frame of the machine on which the parts kare mounted. These parts include a bank of keys arranged in denominational series, each key provided with a stem by the depression of which a stop corresponding to the numeral value ofthe key depressed is interposed in the path of rack bars 2O one for each numeral wheel. These are each provided with toothed racks 21 on their upper edges and are supported a-ttheir frontends upon links 22 suitably i vided. These numeral wheels displayv in proper order on their edges (not shown)fthe numbers vfrom 1 through 9 to 0 and are all mounted on a common shaft32, there being one numeral wheel for each denominational series of keys. It will beA` readily understood that when the rack bars are moved forward and the racks are in mesh with the pinions 30 the extent of the rotation of the wheels is determined by the extent of such movement of the racks which movement is in turn governed by the position o f the key stops above referred to and which is ermanently controlled through a series o other stops 25 provided for that purpose.

The machine is actuated by a handle which oscillates a shaft (not shown) which in turn through appropriate mechanism i'eciprocates the rack bars 20 and through printing mechanism. This latter comprises a series of type bars-50, arran ed in ver-- them movement is communicated to the the proper one is positioned opposite the Y vpoint ot priiit'which is in a. iiXed horizontal plane opposite a sliat't on which is mounted-the platen 53'.f-a1 idj which is placed'ina carriage l adapted to move laterally across the machine,

At 'each side of the .framework of the machine, there are provided bell crank levers 60 pivoted at 61. One arm 62 of the lever is hinged to a steniGB of a key Get providedwitli a finger ypiece 65 projecting abffn-c-the'u1ipeicase of the machine.l The other arm 66 is provided at yits lower end` with a'hook 67 adapted to'swing under the vnumeral wheel shat'tSQ to support it. This key'and'its stem, when-depressed, is adapted to. swing the bell crank lever to move the hooks 67 upward and thus to lift the n.u-

meral wheel' shaft 32 so that the rack bars ifoscillated, cannot engage with the pinionsl 30. In other words, the purpose ofthis key which is called the elimination key vis tofinterrupt the function of the adding-mechanisinso that, while the depression of the numeral keys will cause the registration of the corresponding numbers on the paper 'record provided for that purpose, yet so long as the key is depressed suchitems will ntvbe added bythe machine.l

. The parts above. described form 'no part of my invention but are described and claimed in the application fora patent of Charles N. McFarland, Serial No. 335,357, above referred to. My invention relates to the ininng ribbon and vits related parte;

Ata coni nient place on each side ofthe l trame 1 are. mounted vertical spindles 100. 10,1. On theseare-placed two ribbon . spoblsv 102, 102, ofnsual construction .each

- z )rovided witha central aperture-103 engaging with one of the spindles on which the spools turn and on'which they alle free vertically to reciprocate. Each spool is provided with an upper horizontal flange 104C connected to its u pper plate by a collar 105. The spools are supported in a frame consisting of a cross piece 106 provided at each extremity with a fork 107 adapted to embrace the collar 105. Projecting outwardlyt'rom the cross piece 106 are ribbon guides 107,107, provided with horizontal flanges P108, 108, between which an inking ribbon 109 is adapted to move.v Back of vthe spool frame is a lifter comprising two levers 120, 120. rigidly fixed to a cross rod 12.1 suitably mounted in the frame of the machine and which rod is provided at one end with a rearwardly extending lever 122 adapted tdicoperate with the lower end of `the key stem 63, so thatwhen the key is depressed the lever is tilted, to move the levers 120. 120, 4which in turn lift the ribl .bon spoolsto bring the lowermost strip o f ribbon 110 to the point oi'- print. This strip is of a different color from the-upper part the ribbon and is preferably saturated with red ink. Itwill thus be seen that when the elimination key is depressed,

and so long as it is held depressed, the items set up by the numeral keys will be printed in red and will not be added into the machine. A spring 130 retracts the lever .122

`to its original position and restores.- the black ribbon, to the point of printasjsoon as thej key is restored toits original position.

' It is obvious that some modiiications may be made Vin tlie described construction without departing from the principles upon which the `invention is.based. l. may for.

'instance use a plurality of single ribbons vinstead of a multi-coleredwide. ribbon.' I .may use more thanv tworibbonsand provide means for lifting any predetermined one of' the series into the printing zone, the

color so positioned 'beingindicated by an identical color 'of a key on the key board.

1. In a machine of the class described,` vaccumulating mechanism, printing mechanism, means for s imultaneouslyoperating both of said mechanisms, an elimination key, the depression of which causes an interruptionot the operation of the accumulating mechanism, and an inking ribbon supporting frame, in combination with means wherebythe mere depression of the elimination key will automatically move tuated by the means for holding the nu-A meral wheel out of operative position.
