Abstract
17,035. Bahmann, G. A. Aug. 3. Calculating -apparatus. - Calculator rolls for multiplication and division are made with three separate bands mounted on separate rollers, but turning together, and bearing the products ( 1 to 50) X ( 1 to 50), (1 to 50) x (51 to 100), and (51 to 100) x (51 to 100). respectively. To counteract the effect of dampness on ribbons of linen or similar material, the smaller rollers are mounted on side-bars m, pivoted at l, guided in slots, and supported by springs n. The larger rollers are geared together by friction-wheels or otherwise, and are turned simultaneously by means of a handle on the shaft of the middle roller. The springs n also serve to keep the bands in position after turning. The cross-bars o, p, q show the respective factor-figures 1 to 50, 1 to 50, 51 to 100. Indicators r, s, t are movable on guide-bars u, v, w. To economize space, the product numbers may be arranged in their squares in a diagonal direction.
