UNITED STATES PATENT OEEICE JAMES E. A'rWooD,-o1a` PITTSBUEG, PENNSYLVANIA.
IMPROVEMENT INCRUCIBLES FOR MELTING IRON AND STEEL.
Speciication forming part of Letters Patent N0. 108,084, dated October 1l, 1870, antedated October 8, 1870.
To all whom -it may concern:
Be it known that l, JAMES E. ATWOOD, of Pittsburg, Allegheny county, and State of Pennsylvania, have invented a new and useful Improvement in Grucibles; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part 4of this specification, in Which- Figure l is arepresentation of a Crucible with my improvement. Letters A1A are the flux-ringer convex ring. Fig. 2 represents a Letters B an inside former, all that is necessary to do is to cut out a concave in said former about three inches in length and about onehalf inch deep. The concave in the former Will make the convex ring or bulge A A.
A crucible made with my improvement is not only stronger, but Will run one more heat than a Crucible made oi' the same material will run Without it, and less danger of breaking.
There may be a slight bulge on the outside of the crucible; but that would interfere with the handling of the Crucible with the tongs.
Claim.
I Claim as my invention- A Crucible for melting iron, steel, and other metals, when constructed with a iiux-ring, as herein described, and for the purpose set forth.
J. E. AATVVOOD.
