Shay locomotive patentIn 1881, a U.S. patent was issued for the gear-driven steam locomotive invented by Ephraim Shay (No. 242,992). He designed an engine suitable to haul heavy logging trains at low speeds over rough terrain with even poorly-laid, uneven track, sharp curves, and grades up to 14 percent. The locomotive bogie-wheels were formed with bevel-gear teeth driven by a bevel-gear on a shaft directly connected to the engine. Power to the shaft was transferred through a crankshaft and universal joints from vertically mounted pistons. Having been in the saw-mill business since 1869, Shaw developed his locomotive when he saw the need for a better way to move logs harvested from the forest to the mill to replace horse-drawn sleds.«[Image: detail from patent diagram showing bevel gears on wheel and longitudinal drive shaft.] |
