10 all whom t may concern:

Beit known that I, JOHN GJERs, a subject of the Queen of Great Britain and Ireland, residing at Middlesbrough, in the North Riding of the county of York, Kingdom of Great Britain and Ireland, have invented new and useful Apparatus for Equalizing the Temperature of Steel Ingots, of which the following is a specification.

My invention relates to improvements in apparatus of the kind described in the specifica tion of an application for Letters Patent of the United States iiled by me on the 18th day of April, 1882. According to that invention steel ingots are converted into a finished or partly-nished state, without reheating them in a furnace, by the aid of vertical soakingpits, built in a mass of brick-worky or other refractory material, and each of a cross-section slightly larger than that of the ingot, and of a depth slightly greater than the length of the ingot. Each ingot, immediately after being stripped from the mold, is placed in one of these pits, and after the mouth of the pit has been closed by a cover or lid, is there allowed to stand until its heat is distributed, audit assumes a suitable temperature for being rolled or otherwise pressed into a bloom or finished article. According to that invention a portion of the heat of the ingot is communicated to the brick-work of the pit, and tends to maintain it at a temperature equal to that at which the ingot should leave the pit, so that should an ingot from any cause arrive at the pit short of heat, its temperature will be raised by heat from the walls of the pit itself, the refractory mass wherein the pit is formed acting as an accumulator of heat.

Now, my present improvement relates to apparatus of the kind above described, and is designed more particularly for use in works such as open-hearth steel-works, where few ingots are made in a shift, or where the pits maybe required to contain the ingots for a long time or be empty a long time. In such cases it is important that the heat shall not wbecome dissipated by escape through the top ofthe pit, and to this end I employ a cover which comprises a deep block of brick of great depth, and which extends downward into the interior of the pit for a considerable distance, and is there retained by means of a metallic plate, to which the said block of brick: or refractory material is suspended by bolts, the heads or nuts of which are situate in recesses formed in the under part of the said deep block of brick, and which recesses are filled in with refractory material, to protect the bolts.

The accompanying drawing illustrates in vertical section a pit with vmy present improvement applied thereto. The pit a is, as explained in the specification of my application above referred to, constructed in a mass of brick-work, b, and the ingot o rests on a bedding of sand, d. The walls of the pit-s are constructed of brick-work, and separated from the surrounding brick-workb by thick joints of re-slag-a construction similar to that described in my application filed March 23,1883, No. 89,277. Around the mouth of the pit the top of the brick-work is covered by the castiron plate e, rabbeted at f, to receive and forni a seat for a plate of suitable metal-such as castirOn-g, constructed with a llet, h, to receive the upper end of the deep block of brick z', which is rabbeted, as shown, so that the shoulder formed by the rabbet bears against the under edge of the quadrangular fillet h, between which, however, and the lateral parts of the upper end of the blockz' sufficient space is left to allow for expansion and contraction; also, with the same object, aspace is left betweenthe top surface of the block v3 and the under surface of the metal plate g.

7c 7s are two bolts, with eyes or handles at their upper ends and screw-threads at their lower ends. These bolts are passed through the block, so that their screwed ends enter the recesses Z, and the bolts are tightened by nuts within the recesses Z, which are filled with refractory material, as already stated.

I do not herein claim the process of equalizing the temperature of steel ingots by the use of the apparatus herein described, nor the general construction of the apparatus, such having been made the subject of separate applications; but
