Appl. No.:

6/514940

Inventors:

Lyman W. Jeffreys - Barrington IL

Assignee:

AMSTED Industries Incorporated - Chicago IL

International Classification:

B61F 900

US Classification:

104247

Abstract:

A pouring tank assembly and transfer tracks are provided whereby a transfer car holding a pouring tank filled with molten metal can be rolled from a loading station to a pouring station. The transfer tracks are of a double rail configuration, with two tracks forming an angle whose vertex is at the pouring station. A third guide rail parallels each set of tracks. The transfer car is equipped with flangeless wheels which roll along the transfer tracks, and has a support arm from which guide rollers extend. Such guide rollers contact the guide rail to provide lateral stability for the transfer car.

Inventors:

Lyman W. Jeffreys - Barrington IL

Assignee:

AMSTED Industries Incorporated - Chicago IL

International Classification:

B22D 500

US Classification:

164323

Abstract:

A pouring assembly for use in the manufacture of cast metal articles is provided. After a mold is filled with molten metal at a pouring station, it is lifted to a set down station. Simultaneously, an empty mold is lifted from a pick up location to the pouring station. After a hold down mechanism is set on the mold, the mold is filled with molten metal injected upwardly under pressure into the mold and a mold stopper is closed to prevent the molten metal from running out when the injection pressure is relieved.

US Classification:

432 11

Abstract:

The present invention provides a method and apparatus for determining the temperature of an object as it moves through a heat treating furnace. The furnace includes a hearth adapted to move through it thusly enabling a number of objects placed on the hearth to be heat treated as they move through the furnace. To obtain the temperature of an object being heat treated as it moves through the furnace, a hole is provided in the hearth. A thermocouple wire is inserted through the hole and into the furnace. An end of the wire is connected to an object being heat treated, and the object is placed in the furnace. The other end of the wire is connected to a temperature display device outside of the furnace which moves along with the hearth and the object as they move through the furnace.
