Williamsport Gas Engine Co.
The Williamsport air cooled engine made its debut in 1908. As with the water cooled engines, no data concerning the various sizes available had yet been secured. Coolling was effected by a large centrifugal blower mounted directly to the engine crankshaft and visible behind the flywheel. Suitable piping carried the cooling air into a shroud beneath the cylinder for even distribution. To futher enhance the cooling effect, Williamsport air cooled engines featured an auxiliary exhaust port. the company claimed that about 70% of the hot exhaust gases passed through the port, thus making the task of cooling the engine much easier. After 1908 the Williamsport engine passed form view.
history
The March, 1907, issue of Gas Power carries the first public advertising of Williamsport engines. Despite this fact, the engine may have been in production fo rsome time previously – many engine builders stayed with a local market initially, and many more never graduated past this point. Although an exact range of sizes had not been determined, Williamsport is known to have built engines of at least 15 horsepower in size, and possibly larger. Eccentrics were used to actuate the valve gear mchanism, similar to steam engine practice. Throughout the engine, every effort was made to emulate steam engine design and thus provide an engine nearly as quiet and every bit as dependable as steam. Hit-and-miss governing was stanard equipment, with a volume governed design available on order. Williamsport solved the problem of lubricating the crank pin by providing a small sight feed lubricator at the end of the cylinder. From it, oil dripped into a small collecting pan on the connecting rod, where it was conveyed by tubing to the wrist pin bearing.
