Original industrial trade vintage catalog for SANFORD RILEY STOKER COMPANY, LTD, was located in Worcester, MA. Manufacturers Self-Dumping Underfed Stoker. Applied to any boiler, either water tube or fire, the Riley stoker is also adapted for heating and smelting furnaces. Pictured is a perspective view showing relative movement of furnace parts and a sectional view showing operation. Disbound from a large 1916 industrial catalog, this unique old one page technical brochure would display beautifully matted and framed. A marvelous addition to your retro industrial equipment library. Page is detached and may contain a small amount of residual glue on edge.
