Abstract

328,455. Odegaarden, H. May 7, 1929. Slide-rules.-A slide-rule of disc form has a pair of discs 30, 31 secured together and spaced apart by a cylindrical hub 41 on which can rotate three other discs 32, 33, 34 of progressively increasing diameter. The discs are graduated in terms of dimensions of boxes and of freightage thereon. Ordinary logarithmic scales may be carried by the two top discs and additional discs and scales may be provided for trigonometrical factors.
