Abstract

335,379. Lewis & Tylor, Ltd., and Lawson, N. Oct. 1, 1929. Slide-rules for belt transmissions. - The fixed portion of the rule carries a scale e of pulley diameters, and a number of scales f of belt widths corresponding with the type of belt. The slide is graduated for pulley revolutions and horsepowers and is slotted at c to enable a fixed scale d of belt speeds to be read.
