To all whom t may concern.'
vBe it known that I,- BENJAMIN a citizen of the resident of vWheeling, and State of West Virginia, have invented certain new and useful Improvements in Soaking-Pits, of which the following is a specification.
This invention relates to the construction of furnaces for heating metal, and more particularly to furnaces known as soaking pits,. and used in'heating ingots preparatory to the Aingot rolling operations.
The high temperatures'employed in soaking pits in heating ingots for rolling, causes the coping plates and other metal portions of the mouth ot the pit to burn and warp,
and when the refractory walls wear or crumble, the tops will sag so that they must be replaced, necessitating the shutting down of the pit, and entailing a considerable eX- pense. y t
With my invention, the metal tops are artificially cooled to prevent over-heating and its accompanying evils. Experience has proven that the life of a pit is materially lengthened by the use of my invention. YVith the old style of pit it was necessary to rebuild the pit about every six months,
while with my improved torni, a pit will last from twenty to twenty-one months. The advantages of being' able to continually use a pit for such a l'ength of time without requiring repairs will be lobvious to anyone skilled in the art.
.One of the principal objects of my invention is to provide an articially cooled top that may be applied to the ordinary approved design of soaking pits.
Another object is to so construct' such topl that it may utilize water or other cooling fluid for cooling purposes. i
,A further object is to generally vstrengthen and improve the top construction of soakin pits. Y
lther objects and advantages will be readily apparent to those skilled in the art, and will be moreJ particularly described and pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which'- Figure 1 is a top plan View of one of a bank of soaking pits embodying my invention. y

Application led November S, 1920. Serial No. 422,449.
Fig 3 is an enlarged fragmentary top plan view of a part of the battery o t units shown in Fig. 1, with the covers removed.
Fig. 4 is a cross-sectional view on the line IV-IV of Fig. 3, partly broken away and showing the cover in broken lines.
Fig. 5 is a sectional view on the line V-V of Fig.l 4.
In the drawings a bank of three pits is shown. any number desired maybe used. The pits have side walls 2 and front and back walls 3 and. 4 of refractory material.
Mounted on top `ofthe side walls 2 are artificially cooled top plates or tracks B on which the topclosure or door A rides. The tracks or top plates B are composed of cast ymetal and have a base portion 5 adapted to abut and be secured to the top of the side walls, and a track or rail portion 6. The track portion 6 is centrally arranged on the plates, which are adapted to be secured However, it will be 'understood' plates to prevent overheating and its accom-z disadvantages.
The pipes Y extend past the front end of the plates B, and a spacing plate 16 having suitable spaced apertures is passed over the panying pipes and serves to bind the forward ends of the plates B together in spaced relation.
Other rail or track members 8 are adapted to be secured to the rear end of the track members 6 by means of -shaped anchors or coupling pins 9, and extend rearwardly over theregenerators for the pits (not shown), for the" door A to ride on when moved away from the pit. y
The door A is of the ordinary arch construction, having binding side plates 10, anl
arched portion 11 of retracto material,
land-having axles 12 journaled 1n bearingsl 13 carrying wheels 14. lThe door A.' is adapted to be moved back and forth upon the track portions 8'. and 6 in any well-known draulic cylinder 15 or When the manner, as by a h ics door A reaches the. point of travel at which the wheels 14;. are inthe-depressions or rrefcesses 6', the edges of the body will strikethe base 5` of the top4 plates B, thus closingfthe pit.
The vgeneral operation of the pit iswell-` 'known to those skilled'in the'- art, and will notbe discussed here in detail. particular attention is directed to the cooling.
