desired, yand folded along the said margin lso that the front and back leaves are exibly connectedand formed in one integralpiece,

and provided with a space 5 therebetween. The" opposite extremities of the front Aand back leaves 2' and 3 are, by preference, connected by means of one or more pivots or eyelets 6, (i, which maybe formed of metal orv other suitable material, each of said eyelets being langed at'its opposite ends, so asto holdtheleaves 2 and 3 through which the `eyelets extend, in position. .The eyelets 6, 6, alsok serve as Supporting pins: orr axles 'for rotatively supporting a lpair of computingor number 'wheels or disks 7 and 8 which are rotatively mounted on said eyelets 6,6, between the front and back leaves 2 and 3. Eachofthe rotative wheels or disks 7 and S is located between and adapted to project outward beyond opposite. curved marginal portions of the front and back leaves 2 and 3. The wheel 7 is'located between a curved marginal portion or rounded corner 9 olf the front leaf 2 and a similarly curved orrounded corner marginal portion 10 of the back leaf 3. And the wheel 8 is located vand adapted to rotate betweenv a curved or rounded corner marginal portion 11 of the front leaf 2 and the opposed rounded corner inarginal portion `12 of the back leaf 3.

The rotative wheels or disksv 7 and 8 are each provided with a. series of peripheral marginal vnotches 13, by preference, ten of said Vnotches for eachwheel, all of said notches project outward beyond theA outer `curved corner marginal portions 9 and 10, and 11 andy 12,.into`position to permit the end of the linger or` linger nail of the operator to be inserted in'said notches respectively, in

il l) all any desired order, in the operationof turningl the Wheel or Wheels and stopping them as required. And marginal notches yor recesses and 16 are provided in the opposite side edges oli' the -front lea-'f 2 and back vleaf 3 at the lower outer extremities ofthe curved or rounded corner marginal portions 9, 10, 11 and 12 respectively, and vare adapted to engage and serve as stopsV for: stopping the linger of .the operator .in position to cause the adjacent computing Wheel or disk to stop in proper position as required, 'Whenever the Wheel or Wheels are rotated or partially rotated intermittently or in `a stepby-step manner inthe ogeration of the device. Y

' The sheet, card or tablet 1 is provided with a series of correlated groups or columns of numbers 17, 19, 19, 20, 2l, 22, 23, 24, of which there may be any desired number. In theform of the device shown in the draW- ings there are eight groups or columns; and they lare each j iroviiiled with an individual distinguishing` mark or letter at the top of each group or column respectively, for eX- ample? Ajay 44B, C517 D577 E, In, G and E, in lpredetermined order.

The curved or rounded corner marginal portion 9 of the liront leaf 2er tablet is provided with a series of equally spaced lmarginal 'graduation marks 17', 18, 19', and each having an individual distinguishing mark or character, for example A, B, C, and D, in their order, corre spending with columns'or groups ofnumbers having like individual distinguishing marks or letters above described.

rlhe curved or' rounded corner marginal portion or segment 11 ofthe front leaf 2 or tablet 1, has a similar series Vof equally spaced marginal graduation marks 21', 22', 23, and 2li', each having an individual distinguishing mark or character Which is, by preference a duplicate of and corresponds with a like distinguishing mark or character of a corresponding column or group, for eX- anllale, GEEN. lr7 6G27? n11dtl, Order shown in the drawing.

Each of the rotative computing or number y Wheels 'i' and 8 has a series of numbers theref on, said numbers being, by preference, on the backs of the Wheels and facing toward and adapted to be normally covered and concealed by the back leaf 3, cach of said numbers being adjacent to and corresponding with a peripheral notch 13,' or a peripheral projection 14- on the same Wheel.

The series of numbers on the vvlieelor disk 2" is indicated by the reference number 25; and the series of numbers on Wheel 8, by the reference number 26. Each oi said series of numbers and 26 includes, by preference, the ten digits l, 2, 3, 4, 5,

6, 7,8, 9, 0, arranged in ya circle in consecutive numerical order.

The back leaf 3 has an opening27 there in across Whichthe numbersfcontained in the series 25 on Wheel 7 are adapted to move as said` Wheel is rotated intermittently, or in a step-by-'step manner, said opening ybeing rotated at the reading position for said numbers, and adaptedto uncover and expose any number in said series which is moved vto and permittedto stop Within said opening,

and particularly any number Which is to be readwnr ascertainedand revealed, for yexample, the number 9, as shown in Fig. 2. Asimilau opening` 28V through the back leaf i is formed, adjacent to the opening 27; and across this opening 28 the numbers contained in. the series of numbers 26 .are adapted to move in .successive order as theWheelSvis rota-ted,intermittently or in. a step-by-step manner, said opening 28 being located at and adapted to indicate thereading position for said numbers on wheel 8,2and being adapted to uncoveiand expose Vany number in said series in the order in Whichit is moved to and permitted to stop Within said opening, and particularly any number which is to beread or ascertained and revealed, for ez;-v ample, the number 5 as shown injFig. 2.

The series of numbers onv fthe movable or columns of numbers on the stationary titl member or-tablet, as Well as the identifying letters or characters` at the tops of the groups` and the correspondingI lettersand lgraduation marks on the front leaf 2 of thetablet 1, are correlated, although'the eX- tent. and character of the relations vof thesevariouselements, and particularly the relationof the movable numbers'on the rotative wheels to the groups of stationary numbers and characters, and to the individual num-V bers in said groups .is not so obvious and is not intended to be so obvious as to be readily recognized and understood upon a mere Asuperficial inspection or Without giving the matter some consideration. It is believed, however, that a brief explanation of the game and of the device and its op eration will enable the invention and the relation of said elements to be readily understood.

The rotativeV Wheel T and the numbers thereon are related to all of the groups or columns oli-numbers on the stationary sheet or ktablet 1, but more particularly tothe four groups or columns which are identified by the letters Af 'B, C and 1), respectively, and which constituteone series of groups or. columns.

The numbers 1`,f23, and Lle, on the rotative wheel -7 may be considered as constituting imlividual group-distinguishing title numbers by which said four groups constituting said series are individually represented and numbered in consecutive numerical order which, in the form of the device here shown.

`1,666,641 fr Yz3 .corresponds Vwith lthe lalphabeticalorder and relative positions of said groups so numbered although the relative positions of the groups and of the characters and marks on the stationary member Aor tabletvmay be changed-or arranged in any desired orderV provided each stationary group or column of numbers is correctly represented dby its proper titlevnumber orinovablenumber on the proper compu-ting Wheel. f,

.The movable computing member or rotative number Wheel 8 and the series ot' num` bers thereon are related to all of thefgroups or columns .of numbersv ontli-e stationary tablet l, or front leaf Zot' said tablet, but more particularly to the fourv groups or co1- uinns which are distinguished from eachy other or identified by the letters E, 3F,V

G and l-l, respectively, and which constitute another or secondrseries ot' tour cor-` related groups or lcolumns of numbers which contain two-digit @numbers but nol singledigitnui'nbers, the single digits on the tab-yl Jroineach other and numbered in consecutive numerical order.. The numerical order inthis instancecorresponds with the alpha-p.

betical order and relative positions of said groups; but the alphabetical order and relative lpositions of the groups on the tablet.

may be altered or arranged as desired, providedv the correct relation ot' the movable group-distinguishing or title numbers on the movable or rotative computing-` wheel or Wheels with respectto the groups which the titlenumbers represent is preserved.

The correlated groups or columns of numbers on the stationary member or tablet 1 in clude.bypreference, all of the numbers from l to 99 inclusive, some of which are contained in one group or column only, and others of which are contained in each of a vplurality of said groups or columns. And the series of numbers on the Wheels 7 and Smay or may not contain numbers which numerically distinguish or represent the related groups ot' numbers, or the fnumerical order of arrangement of said groups; but it is believed that the invention and the operation ol the device can be more readily and clearly explained and understood by con sidering the groups or' columns on the tabletV as being represented, theoretically if not actually, by corresponding numbers on said Wheels, as above indicated- :The first four correlated groups,y lettered A, 13, C, and 1), respectivelyy contain all of thesingle ldigits or single-digit numbers, and some ofthe two-digit num;v

bers; and-the second 'series of four groups, lettered fil, Ff-G and H, respectively .contain vtwo-di git numbers ,-only, the lowest number rbeing 10,y and the highestbeing, bypreference, 99, although less Vthan v innetyfnine numbers may,y of course, be em-v ployed if desired;
