To aZZ whom it may concern.- -Be it known that I, HAROLD JARvis, a citiresidin at Buiialo, in the county of Erie and State o have inventednew and useful Improvements in Tabulating Mechanism OrType-Writing Machines, of which the following is a speciiication. This invention relates to type-writing machines havin a tabulating mechanism or attachment. machine having such a tabulator is shown and described in LettersPatent .of the United States No. 753,796, issued to me March 1, 1904. Such .attachments usually comprise means for lifting the gearrack'or rack-bar of the carriage out Oi engagement with the esca ement pinion or pawl, a series of movable enomination dogs or detents actuated by a row of keys which are .located at the front of the machine and which also control the lifting device of the gearrack, stops adjustably mounted on a supporting-rack secured to the carriage and adapted to encounter said denomination-dogs for arresting the carriage at the desired points, and
adjacent to said tabulatingkeys and indicating the denominations represented by them. The objects oi my invention. are to combine'with the tabulating-keys a simple and convenient scale which permits the machine to be readily adapted to tabulating withhor without commas, as desired, and to provide eiiicient'clips or holders for the scale.
In the accompanying drawin s,.consist1ng of twosheets, Figure 1 is a top p an viewof a type-writing machine embed ng my imiovement, showing the side o y I the ordinary arrangement ofthe indications ior tabulating without commas. Fig. 2 is a detached view of the scale-bar, showin its o Osite or the indigcationldparranged for tabulating wit commas.

Vparticular stops illustrated in the drawings eing rotatable on their carrying-bar, as shown and described in the patent is made for a complete description and illustration of such tabulating mechanism.
My invention is combined with the tabu- .the other members of the ating mechanism form no part thereof, to show them fully tabu it is deemed unnecessary in the drawings.
G indicates the tabulatinU-scale, which in the construction shown in igs. 1 to 5 of the drawings consists of a bar arranged a short distance above the tabulating-keys D D1 and reversibly means. The preferred' devices consist of a pair of clips or holders H, having forwardlyfacin springz-iingers h, which bear upon the scaleai'. ach` of these clips consists of an angle-plate, which rests upon and carries the spring-finger h,
the front bar of the frame clips are securely fastened a ainst the front sidelofsaid frame-bar by c am s I, which may also serve'as supports for t e horizontal bar J, in which the stems of the tabulating-keys are guided, as best showninFi .4. i
On one'si e the'scale-bar G bears the usual decimal-point' g and the" numbers 1, 10,v
and D D7 tlie auxiliary keys or pusli.
which is- `formed integrally therewith. The lower attached to theupper edge of the f'ront bar of the rameA by any suitable the upper' horizontal flange of 100, 1,000, lue., located. in line, with the corresponding tabulating keys D. D?, as shown in Fig. 1. When the tabulator is used with that scale and a tabulating-lrey is de pressed, the carriage is allowed to travel the desired distance before being arrested, ac cording to the adjustment of the stops F, no provision being made for comma-spaces between the hundreds and thousands columns the millions columns Where the attachment has the capacity to tabulate in excess of hundreds of thousands. Onits opposite or reverse side the scale-bar bears a decimal-point g and a similarseries oi numbers and also, preferably, a "comma gv2 between thehundreds and the thousands indications. The numbers indicating units, tens, and hundreds on the last-named or reverse' side of the scalebar are located directly opposite the correspending numbers on the obverse or iirst named side of the bar; but the numbers on said reverse side which indicate thousands tens oli-thousands, and hundredsfof thousands are each advanced or offset one step of the scale with reference tothe like indications on the obverse side-that is,l a distance corresponding to the space between adjacent tabulating-keys-so that said numbers come opposite the numbers on the obverse side indicating ten thousands, hundreds ofthousands, and millions., respectively. In other words, that tabulatingekey which under Ythe ordinary scale represents one thousand simply rc resents .a comma-space under vthe other scale containing the comma, and the key which under the' ordinary scale represente ten thousand indicates one,thousand under the scale containing the comma, and so on throughout the reinainingindications of the scale.
opposite the thousands indication on the ob- "erse side of the scale-bar.
l angcment i:` t upon reversing the scalebar from the -n shown in Fig. l to that illustrated in Fig. 2 and pushin say, the kev .D5 for 'writing one thousand t eearriage opped one 'lettenspace `sooner thanby pusaing the lrey corresponding to the thou- 51:- `lds designation imdertfliescaleshown in` i, thusleavingiaspacc for@ comma be een the hundreds'endtliousands columns', exam le, i 'slxouldithe .operator desire to te t'we ve thousand nine lmndredy and sixty-live in tabulating with the com ma- S .ted in line with the ten-thousands designa- 1 ofthe sca-le 'and then operates the usual Iig-keys 'representing the numerals l lie-comma, and thenumerals "-Qfl 65. l.5, inthe order named. he comma-scale shownfinfthe drawmgs esas at'lhundreds of thousands, and henceA and'bctween the hundredsfo-thousands and The comma g2 when used comes The effect of this bears but a single comma. It is obvious, however, that'it may include higher denominations, and in Jrhat case a second comme. is arranged betwee.V1 the hundredsof-thousands and millions columns and another between the hundreds-ot-millions and billions columns. `When 'the scale runs above hundreds of' thousands, the `millions indication on the comma-scale is oil'set two steps 1n advance ci' the corresponding indication on the ordinary' or non-comma scale, and so on.
The scale can be readily changed to tabulate with or Without the use of commas, as may be preferred, by withdrawing the scalebar from under the spring-clasps h and then reversing and replacing the bar. A
By this simple im rovemcnt a duplex scale is provided whic i requires no changes or modications in the construction ot the tabulating-lreys or other members of the tabulating mechanism and Which enables an operator to readily adjust the attachment to suit the fancy or preference oi the princi aal as to the useor omission of commas in ta .ulated Work.
. The comme shown on the scale-bar in Fig. 2 may be omitted; but it preferably placed thereonto enablethe operator readily to distin uish that particular scale from the other.
nstead of arranging the two series of indications on opposite sides of a reversible scalebar they may both be arranged on the same side ofthe bar, one belov,T the other, as shown in Fig. 6. In this case provision ispieierably 'made for concealing the scale series not 'used by the operator. For example, this may be done by hing-ing a plate' or screen K centrally to the face of the scale-bar, so that the same may be readily swung downwardly over the lower series of indications or upwardly over the upper series, as desired. if preferred, the scalefbar may be provided With the oominafsc'ale only.r
AIn each of the constructions herein described the scale provides fora comma `space or spaces between the desired numbers of the tabuiating series. Y
I claim as my invention# l. The' combination with the denominar tion-keys o? a t' evrriter tabulating meehanisri, of a duplex sca-i located adiacer said keys and -zzvomprising t tions registering with. the respect.. some of the indications one of said. s le. being olset with reference to like indications in the other series, whereby the two series may be employed interchangeably for tabulating with or without commas, substantially as set forth.
` 2, The combination with the denommation-keys of a tyie-writer tabulating mechanism, of 'a reversible duplex scale-bar lo- .cated adjacent to said keys and4 bearing on one side a' series of indications arranged to register With said keys, respectively, and on its opposite side a similar se'ies of indications, some of which are offset with reference to like indications of the other-series to'ieave, comma-spaoes-between sonie oi the mdlcaf' tions, substantially es set forth.
