ABACUS.
!PBCIPICATION forming part of Letters Patent No, 352,218, dated November 9, 1886.
Application filed JulyE, 1886. Serial No. 207,399. (No model.)
T aZZ whom ?lt may concern:
Be it known that We, GEORGE W. BOLTON and CHARLES I-I. TILLMEYER, of Milwaukee, in the connty of Milwaukee and State of Wisconsin, 'have invented neW anduseful Improvelnents in Abacuses; and We do hereby declare the following to be a full, clear, and eXact description of said inVention, reference being had to the accompanying draWing, and IO to the letters Or figures of reference marked thereon, which 'form u part of this specification.
Our invention, to be hereinafter distinctly claimed, consists in the peculiar construction I 5 of a simple and ineXpensiVe abacus so formed as to hold all the counters on a single Wire and permit the removal of all of them from the enumerating-line singly to one or both Sides thereof; in the construction of the counters and the peculiar form of the Wire,Whereby only one counter can be removed from the enumerating-line at the same time.
The drawing is an elevation of our device. The single counter-supporting Wire of the abaous consists of the Straight enumeratingline A, the angles B B','curved ends or neoks C C', the counter reservc lines D D', and the tangs E E'.
The Straight enunierating-line A is Sntioiently long to hold o number, preferably tWenty, of buttons or connters, G G', and termin nates at both ends in outWardly-turned angles, intended to Check the outward move- Inent of the counters when on the line A. 5 The neck C is a Curve so proportioned that tWo counters, G" G", cannot be pushed along over the neck at the same time, because they Would be so inclined inWardly toward and against each other on their inner Sides by their 40 different axles on tWO parts of the neck as to bind on the neck and stop their joint progress, While singly the countcrs may be readily moved past the angle B and over the neck O. The line D for holding the counters in reserve .5 is inclined outwardly away from line A,Whereby on each of the reserve lines D D' sufficient space is obtained to hold all the counters that may be oonveniently used on line A. The tangs E E' are inserted rigidly i'n a handle, F. Strung on the Wire are a number of buttons or I counters, G G', preferably tWenty in number, usually of different colors, preferably in alternate series of five of a light and five of a dark color. These counters or buttons ere also preferably provided With a metal bushing, H, in and about the central Orifice, by and through which they are strung on the ire, Whereby great smoothness and ease of motion and great endurance for the counters are secured.
hen this abacus is being used to tcech a child to count, the buttons are placed on the Straight line A, and as they are oounted they Can be removed one at a time from the liiieA to the reserve line D or D', or to both of them, as desired, and by this construction of the abacus a great number Of interesting and instructive methods of enumeration and simple problems in numbers that Will occur to an apt teacher may be readily and plainly performed. V
hat We Claim as new, and desire to secure by Letters Patent, is
1. An abacns consisting of a single countersupporting Wire terminating in' a handle, and a series of counters thereon, substantially as described.
2. In an abacus, the Straight counter enumerating-line A, the curvcd necks O C', proportioned as descrbed, and the counters G GC merating-line A, the angles B B', the curved necks G C', and the outWardly-inclined reserve lines D D', substantially as described.
' et. The combination of the Straight counter enumerating-line A, the angles B B, curved 8 necks G C', reserve lines D D and the counters G G', substantially as described.
5. In an abacus, a counter-supporting Wire, the thereon-strung counters G G' G", and 'the bushing I-I in and about the orifices iu the 0 counters, by and through which they are strung on the Wire, substantially as described.
In testimony Whereof We affix our signatures in presence of two Witnesses.
