Definitions
- This invention is based on the discovery that by heating a piece of iron or steel to a white heat, and at the same time heating a piece of cast-iron of that kind which is used for kettles or other "essels to a melting heat and then quickly rubbing the two together, or by dipping the heated iron, steel, or other metal in cast-iron of the class above described, melted in a crucible for a short period of time, the two will so blend that by at once cooling the same in water it will become so hard that no file will touch it.
- Our invention consists in hardening steel, iron, or other metal by bringing the same, when heated to a white heat, in contact with cast-iron of that class generally used for kettles or other vessels, and heated to meltingheat and then cooling it atonce by immersion in water.
- Our process is particularly applicable for the purpose of hardening iron horseshoes, calks, and toes, boxes and spindles for railroad-cars, wagons, carriages, mills, drag-teeth, wagontires-in short, for all parts of machinery or.
Description
NITED STATES PATENT ()FFICE.
IMPROVED PROCESS OF HARDENING IRON.
Specification forming part of Letters Patent No. 13,813, dated August 9, 1864.
To all whom it may concern:
Be it known that we, THOMAS OHAPPELL and WILLIAM ASHLEY J ONES, both of Winona, in the county of Winona and State of Minnesota, have invented a new and Improved Process for Hardening Iron; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to fully understand and use the same.
This invention is based on the discovery that by heating a piece of iron or steel to a white heat, and at the same time heating a piece of cast-iron of that kind which is used for kettles or other "essels to a melting heat and then quickly rubbing the two together, or by dipping the heated iron, steel, or other metal in cast-iron of the class above described, melted in a crucible for a short period of time, the two will so blend that by at once cooling the same in water it will become so hard that no file will touch it.
Our invention consists in hardening steel, iron, or other metal by bringing the same, when heated to a white heat, in contact with cast-iron of that class generally used for kettles or other vessels, and heated to meltingheat and then cooling it atonce by immersion in water.
- In executing our process We use a piece of an old kettle or other similar vessel or castiron of a similar nature to that used in the manufacture of kettles or other similar articles, and place the same, together with the iron, steel, or other-metal to be hardened, in a blacksmiths fire, and when both pieces are heated ble, so that the piece to be hardened can be readily dipped in the molten metal and then cooled, when the hardening process is accomplished.
Our process is particularly applicable for the purpose of hardening iron horseshoes, calks, and toes, boxes and spindles for railroad-cars, wagons, carriages, mills, drag-teeth, wagontires-in short, for all parts of machinery or.
other articles which-are exposed to particular wear, and when treated according to our process such articles are fully protected against wear, and they will last for a very long time. \Ve claim as new and desire to secure by Letters Patent- The within-described process of hardening iron or other metal by bringing the article to be hardened, when heated to a white heat, in
contact with a piece of old cast-iron kettle or other similar cast-iron heated to a meltingheat and then cooling suddenly, substantially as herein specified.
THOMAS OHAPPELL. WILLIAM ASHLEY JONES. Witnesses:
O. H. BERRY, G. W. WATERMAN.
