original patent


This invention relates to locomotives which l consume their own products of combustion, (called sometimes smokeless locomotives,) of that type which are provided with a revolving fan-blower for creating a forced draft and returning the smoke and cinders from the smoke-box to the lire-box, instead of per'- mitting them to escape into the open air; and my improvement consists in the novel construction and combination of the fire-box, the smoke or-cinderbox, the revolving fan, theengine exhaust, the smoke-stack, and a valve for regulating the draft through the same.
