The invention consists of it casing having at nted therein and pro vided with it series of numerals deposed in a circle and adopted to be successively exposed through on opening in the casing. 'l he disk has concentric series of inpertures within it adopted to be engaged by a pencil or other pointed object, so es to rotate the disk n. desired distance in order to bring the proper numeral in position beneath the opening. An. indicator is actuated by the rotation ol the disk for desiginning hundredn, while the disk is utilized for designating tons and units.

The invention also consists of curtain other novel features of eonst ruetiou and combinations of ports, whieh \riil he hnreinri tor more fully described, and pointed out in tluw-laiins.

l l t; is thought that the advantage in having;- several rows of apertures exposed throu h the opt-nin 11 will be apparent from tie 'loregoin (escription. The aperture serves as a guit e the movement of the l for limiting l inserted pencil and the disk, and therefore by placing the pencil against one end of the 1 opening it and within thelust aperture in the 3 column the disk can onlybe l l rotated three spaces. By placing the encil in the end aperture in the 5 column tli be rotated five spaces, &c. While only four series of apertures have been designated, the same a )pearin in the 3, 5, .7, and 9 columns, it is to be understood that, if l e disk can only desired, a number ofseries of openings may be employed suflicient to provide nine rows instead of four, as above designated. By la-r opening for limiting the pencil no particular providing an irre the movement 0 skill must be exercised in rotating the disk a 1 predetermined distance to cause the proper number to be indicated. It is merely necessnry to move the pencil as for as it will go, i whereupon a correct number will appear in the opening 10.

said tuVtt having characters thereon desig.

, crture l'or successively disclosing the characlOC holdi ters upon the disk, and means carried by the casing for indicatin the number of rotations of the disk, the wiillsof the 0 ening in the cover constituting stops for a isk-operating device. i

3. The combination with a casing having an aperture therein; 01" a numeral-carrying disk rotatably mounted within the casing, sa pear within the aperture, a screw fixed to and rotatable with thedisk, a graduated sleeve engaging and movably mounted on the screw, and an index for holding the sleeve against rotation, -said index ada ted to cooperate with the graduations to in icate the rotations of the disk.

4. The combination with a casing havin an aperture; of a disk rotatably mounted within the casing and having characters adapted to successively'appear within the a ertlire, a screw fixed to and rotatable with t e'disk, a slotted sleeve threaded upon and movable longitudinally of the screw and externally graduated, and a lon 'tudinallymovable mdex projecting into t e slot for movable longitudinally of the screw and externally graduated, a longitudinally-movable index projecting into the slot for holding the sleeve against rotation and cooperating withthe raduations on the sleeve to indicate the num er of rotations of 'the disk, and

numerals adapted to successively ap-i the sleeve against rotation and (:0 operating with the graduations on thesleeve' means for holding the index against displacement within the slot.

6. In a device of the character described the combination with a casing having openings therein; of a disk rotatably mounted within the casing and having characters adapted tosuccessively appear in one of the openings, a series of apertures adapted to appear in the other opening, said last-mentioned opening being shaped to disclose adiil'erent number of apertures in each series, a screw rotatable with the disk, a sleeve threaded upon the screw and externally graduated, said sleeve having a longitudinal slot therein, a standard upon the casing, and

an index longitudinally movable within the standard and normally projecting into the slotted sleeve said index adapted to prevent rotation of the sleeve and tocooperate with ,its graduations to indicate the number of revolutions of the disk.

7. The combination with a casing having an aperture therein; of a numeral-carrying disk rotatably mounted within the casing, said numerals adapted to successively appear within the a ertui'e, a screw fixed to and rotatable with tie disk, a graduated sleeve engaging and movably mounted on the screw, and an index outside of and detachably engaging the sleeve for holdin said sleeve against rotation, said index' adapted to cooperate with the graduation to indicate the rotations of the disk.
