Abstract

632,330. Calculating-apparatus. KEEGAN, E. E. May 14, 1947, No. 13027. [Class 106 (i)] A calculating-device comprises a linkage including two members 14, 15, the ends 16, 17 of which are set along a groove 3 to positions numbered to correspond to two numbers to be, e.g., added, the sum of the numbers being then indicated by another link 11 on a chart 23. The chart 23 may be replaced by others showing respectively the difference, product and quotient of the two numbers. The members 14, 15 are pivoted at 12, 13 to two links 6, 7, themselves pivoted to a plate 4 having a slot 5 in which runs a pivot pin 18 which connects the said members 14, 15 to a link 10 and to the indicating link 11. The links 6, 7 are also pivoted at the points 12, 13 to the links 10, 11. The numbers adjacent the groove 3 may be mounted on replaceable cards.
