UNITED STATES PATENT OFFICE.
JOHN WILLIAMS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO EDWIN CHAMBERS AND CYRUS CHAMBERS, JR.
IMPROVEMENT IN PROCESSES IN CASTING IN METALLIC MOLDS.
Specification forming part of Letters Patent No. 138,775, dated May 13, 1873 application filed January 14, 1873. i
To all whom it may concern:
Be it known that I, JOHN WILLIAMS, of Philadelphia, in the State of Pennsylvania, have invented or discovered a new and 11nproved Mode of Casting Metals in Metallic Molds; and I do hereby declare the following to be afull and correct description of the same.
The nature of my invention or discovery consists of covering the surface of metallic or other molds, cores, or bars against which the hot metal is to flow, and be formed to shape, or in, upon, or around which it is to be, with a thin coating of mad, (minium.) By the use of this coating of red lead I am enabled to cast iron upon wrought shafts, and in iron molds and mund wrought-iron anchors, 850., without the usual blowing or escape of gas and vapor, which usually leaves the casting defective or defaced by wavy surfaces, air-holes, and other blemishes.
To enable others to use this coating I will which other metals are to be cast, for the purpose herein specified.
The above specification of my said invention or discovery signed and witnessed at Philadelphia this 7th day of March, A. D. 1872.
Witnesses: JOHN WILLIAMS.
