Description: |
| According to a writeup in Volume 15 of Mechanics' Magazine, page 477, Stephenson "now employs for each pair of wheels a sort of double axle, that is, a solid axle inclosed within a hollow casing, which serves the purpose of a supplementary axle. The solid axle goes through the hollow casting at each end, and supports, on its extremities the weight of the carriage, while the wheels are fixed to the suppllementary axle exclusively. The principal part of the pressure being thus removed from the solid or rotating axle, it works with less friction, and can be constantly lubricated with greater ease.—Date of Pat., March 11, 1831; of Spec., July 11, 1831." |
