0F NEW YORK, N. Y., A CORPORATIGN OF NEW 'JERSEY TYPE-WRITING morir-Nn Specification of Letters Eatent.

Patented aan. 25, 191e.

Application led October 2, 1908. Serial No. 455,919.

To allf'whom it'may concern:

Be it known that I, EDWARD B. Huss, a citizen of the United States, residing in the borough of Manhattan, city, county, and Statel of New York, have invented certain Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to tabula-tor devices for typewriting machines. I

It is indicated in thev drawing as applied to a front strike machine but is applicable, to other types ot' `machin The invention coinprides the use of a plurality of tabulator bars having different .column or tabular stops formed thereon yor car ried thereby.

In the form in which the invention is shownembodied the several tabulator bars are on zthe carriage and they coperate with a center .stop on the frame, but the invention is not limited to the special form shown. Also the tabular stops on the bars aie formed by projections or teeth on the bars, but they might be otherwise provided and if separate from the bars they may be, of course, adjustable in conformity to well known practice. The several tabulatorbars are each capable of being thrown into and out of operative position and preferably the arrangement is such that when one bar is thrown into operative position another which may be in suoli osi, tion is automatically retracted or move out of operative position. The several tabulator bars are shown as pivoted' at one end and about such pivots they are swung into and out of yoperative position but the invention is not limited to that special arrangement. One of the advantages of the employment of such a plurality of tabulator bars is that in'cases o 'special work, as for instance in filling out insurance blanks, certain definite column 'work is required,'and the typewriting machines may be equipped with a tabulator bar for each arrangement of columns,

and itis only necessary ,for the operator to throw into operative position that one of the bars at any time required. .This aiordsa p quicker-and more certain adjustment ofthe tabula'tor devices than can be had by the adjustment o'f a plurality ot' tabular stops upon a single bar.-

l In the accompanying drawings: Figure 1 is a detail plan view: Fig. 2, .a detail lside .levationz and Fig. 3, a detail front eleva- 10.11.

1,'1, indicate the end platesof the carriage of a front strike machine, from which .extend Vrearwardly, at each end .of .the.carriage, plates 2, shown as separately formed and bolted to the plates 1. Extending between the ordinary `end plates 1 is a barl notched adjacent its ends and carrying adjustable .margin stops 4 such as are shown in iny Ratent N o. 878,892, dated 'December 24, .1907. In rear of the bar .3 ,is the 'forwardly ,and backwardly movable frame stop composed of two members 5, 6, such ,as shown in'said' Fatent No. 878,892. T -he stop m5 imay .as shown iii-that pateiit be .operated or .controlled by a key in the 'keyboard .of the ,machine. The rigid part 5 ofthe framestop cooperates with 4 the ma. n stqp a .located at the left side of .the ,mno ine.; and :the yield- .ing spring'member 6 coperaties witi .the margin stop at the right hand side of the machine and with the tabular or column stops.. In yielding the member 6, until arrested by the ri itlV member 5, throws into operation a line ook both when the member Y 6 engages av tabular stop and the ,margin stop at the left of the machine. As shown and described in said patent there may be'a margin release key. The tabulator key in theboard serves to throw the frame stop rearwardly so that it will lengage the tabular,

stops' yet to be described. All this is shown in m Patent No. 87 8,892 and is well understo The present invention is shown embodied as follows: In'rear of the frame stop 5, 6,

there `is a plurality of tabular stop bars,

three being shown and marked 7 ,ly/8, 9. The -are. all pivoted upon a comino/n pivot b o t 10 mounted in brackets at the left hand side of the carriage. They are spaced thereon by reaction springs -11 each having one free end applied to the plate 2 and its other end to its tabulator bar. The reaction of these springs tends to lthrow the other ends of the bars rearwardly. The last named ends of finger pieces -7, 8, 9. These finger pieces vmay contain words or letters indicating the 1washers about which respectively are coiled the bars are turned up and equipped with v special arrangement of.` columns that anyy particular work requires. yThe bars liave, respectively, tabular stops 72', 82, 92 that are of such number and so arranged as may Abe desired. The several bars are shown as of mere flat sheet metal and' all of them are .guided in slots 73, 83, 93 in the side plate 2 at the right hand side f the machine. Each bar has a catch projection of which that 7,4'on bar 7, and 94 on bar 9 are observable in the plan view Fig. l, and each of such 'catch projections has a cam surface lEivoted on a pin 12, that may be mounted in the margin stop bar 3, is a bail-shaped spring latch 13 common to all tlie catch projections of the tabulator. bars, and having applied to it a reaction spring 14. All the faces fc cam back this latch against its spring and 'the catch projection on each bar is engaged 'by the latch. When a tabulator bar is swung forward into position so that its column stop tooth may be engaged by the member 6 of the center' stop, it is caught and held by the spring latch. When another tabulator bar is needed it is swung forward and its cam face fr snubs back the latch to 4release the bar in operative position, which mits of the tabular bars being in the `form 'of flat blades-having integral projections constituting the tabular stops. Each bar is light and strong and any desired number may be used since each occupies very little ity of tabular barseach havingtabular stops and adapted to move into`and out of opera- `tive position, -andinean's wherebv a tabular bar that is in operative position is automatically moved out of it when anotherot' the bars is moved into operative position and a coperating stop common to all the bars.

3. Tabulator devices comprising a plurality of independent flat metal tabular bars placed with their lat faces opposite one another and each adapted to be independentlj7 moved into and ouiL ot operative position.

4. 'wlabulator devices comprising a plurality of independentv lfiat metal tabular bars each pivoted at one end 'and placed with their flat faces opposite one another and each adapted to be independently swung into and out oli' operative position.

In testimony whereof, I have hereunto subscribed my name..
