RIGHT TO HERMANN SCHIERLOH, OF JERSEY CITY, NEW JERSEY, AND HENRY SOHIERLOH, OF NEW YORK, Y.

IMPROVEMENT IN WELDING IRON AND STEEL.

Spccification f01'ming part of Letters Patent N o. 142,939, dated September 16, 1873; application filed. September 9, 1873.

To all whom it may concern:

Be it known that I, JOSEPH POPPING, of the city of New York, in the county of New York and State of New York, haveinvented an Improved Process of Combining Pieces of Iron and Steel, and iron with iron, and steel with steel, and malleable or other iron with cast-steel, and a compound to be used therein, of which the following is a specification:

The object of my invention is to combine iron and steel; and it consists in, making a compound of borax and iron filings to be used for the purpose, and in the process of applying the same.

In carrying out my invention take hard borax and melt it in an iron pan over fire. When perfectly melted, let it get cold. Then crush it to powder. Then mix one part in weight of this powder with one part in weight of clear filings of iron. Then take the pieces to be combined,

warm one of them slightly, so that the mixture will stick to it then, both pieces being in ironclean condition, sprinkle the warm piece with the mizitnre till it is fairly covered; then place the other piece on this covering, and, while the two pieces are firmly held together, heat them red hot and then hammer them well together.

My compound more firmly unites the two metals together and, in fact, unites them so that they form one solid body, which cannot again be separated into its original parts; and this process, further, makes a combination which preserves, in'greater degree than could otherwise be done, the original hardness and tenacity of the steel, because not heated to so high a degree, and at the same time a combi nation which, by the connection of the two pieces, strengthens them and prevents all pos-- sibility of break. I

By my process of combining iron and steel,

- I have only to use cherry-heat, and do away 1 entirely with welding-heat, and therefore save not only a great deal of fuel and time, but

need not have the steel to undergothe-welding-heat, which very often spoils all of the durability and tenacity of the steel. Havingdescribed myinvention,'whatIclai 1s- 1 I 1. The within-described welding compound consisting of calcined borax and; iron fil substantially as described.

2. The process herein describedjif uniting iron to steel-that is to say, first heating one .or more pieces of metal slightly, then applying the compound, and then joining the two metals and subjecting. them to a red-hot heat,

and then hammering or rolling-them-well toh n i H .n
