UNITED STATES PATENT OFFICE.
ABRAM O. MOTT, OF. PH IL ADELPHIA, PENNSYLVANIA.
,IMPROVEMENT IN IRON CORES FOR. CASTINGS.
Specification forming part of Letters Patent No. 98,5l6, dated January 4, 1870..
1' 0 all whom, itlmay concern.- I,
Be it known that I, ABRAM 0. Mom, of the city of Philadelphia, in the State of Pennsylvania, have invented a certain Improvement in the Cast-Iron Patterns Used for Molding in Sand, of which the following is a specification. My invention relates to the application of zinc to the surfaces of the cast-iron patterns used in foundries for molding in sand,,in such a manner as to produce a more smoothand durable surface thereon. The cast-iron..-patterns now used in foundries are generally coated with beeswax, to give them the smooth surface required and to protect them from rapid oxidation; but in ashort time thegvax, being comparatively a soft substance in Warm weather, soon becomes roughened or Worn through to the iron, and scales off in cold Weather, eausin g the sand to adhere, and rendering a'recoating of the pattern absolutely necessary to produce therefrom proper castin gs. In facing or surfacing the iron pattern, after it has been properly dressed by filing,
drilling, &c., in the usual manner, I cleanse it in acidulated water, and immerse and pass it through azinc bath, in the usual Wellknown manner practiced in what is called the process of F galvanizing iron, and thus produce a uniform coat of zinc over the whole of the surfaces of the pattern. I now remove any extraneous lumps by means of a cold-chisel or coarse file, and then smooth evenly the whole surface by rubbing it with sand-paper, so as to leave a smooth, even, and uniform surface of zinc over the whole pattern. The brushing and tapping to which patterns are necessarily subjected in molding and drawing does not injure these zinc coated patterns in the least, and they will therefore last for years in constant use, while the original cost will be but a trifle more than the first waxing heretofore practiced.
I claim-- As an improved article of manufacture, a zinc-coated cast-iron pattern, substantially as and for the purpose hereinbefore set forth.
ABRAM O. MOTT.
