Description
ABEL WAINWRIGHT, or SPRING CITY, PENNSYLVANIA.
lMPROVEMENT EN FOUNDERS FACBNGS.
Specification forming part ,of Letters Patent No. Q0?,3QH, dated August 20, 1878 application filed a 7 June 8, 1878.
graphite and anthracite, and grind them to a powder, which is afterward bolted. The facing thus produced will be placed in bags and applied to sand molds by dusting. While the graphite is fire-proof, the anthracite prevents sticking. The hardness of an thracite prevents any rapid burning of the material; hence it is admirably adapted for founders facings. Moreover, my combination takes up or absorbs the. moisture of the sand-a matter of great importance in the art.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The combination of graphite or plumbago and anthracite, forming founders facings,sub-
stantially as and for the purpose set. forth.
