Application filed December 26, 1923. Serial No. 682,714.
This invention relates to annealing boxes and the object thereof is to produce an annealing box, preferably of cast steel, which will not sag under the temperatures to which it is subjected during the annealing of sheets, plates and the like.
This object is attained by the construction described in the specification and illustrated in the drawingsaccompanying and forming part of this application. In the drawings Figure 1 is a top view partially in plan and partially in section of an annealing box cover embodying this invention. Figure 2 is-a side view in elevation of said box cover. Figure 5 is a. cross-sectional view of the cover shownin Figures 1 and 2 and in this view, the cover is shown in .place upon a base whiclritself is shown in section, and Figure 4 is a View similar to Figure 3 of a modified form of cover with the base omitted.
The annealing box cover may be of any form desired, but as shown in the drawings which illustrate the preferredfiorm and a modification thereof, the cover is cast from steel, is rectangular and is provided with outwardly projecting corrugations. Corrugations 5 extend across the top (3 and extend down the sidewalls7 and terminate a slight distance from the bottom of the sidewalls. Corrugation 8 extends lengthwise of the top and down the end walls and like corrugations 5 terminate a slight distance above the bottom of the end walls. This corrugation intersects corrugations 5. In the preferred embodiment, the corrugations are V shaped.
In the form shown in Figures 1, 2 and 3 triangular steel stiffening members 10 are positioned within the corrugations and anchored therein by means of ears 11 which are formed on the casting adjacent the corrugations. After the stiffening members are assembled in place within the corrugations,
these cars are heated by means of a suitable torch and bent over onto the stiffening members thereby anchoring the same in place.
The stiffening members 10 are preferably rolled from a steel alloy which will not soften under the heats normally encountered to such a degree as to allow the cover to sag. I have found that high chromium and tungsten steels are suitable for this p .rpose.
In the form shown in Figure 4, the triangular stifi'ening members are replaced by tubing or iron pipe 12 packed with silica sand. The ends of the tubing, of course, are closed to retain the sand and when tubing or pipe is used the contour of the corrugation is changed accordingly as shown in Figure 4.
The sides of the box are provided with lifting lugs 13 and if desired'trunnions may be used in place of the lifting lugs.
The base members with which these covers are adapted to be used are provided with channels 14 formed for the reception of sealing sand as is now common.
Having thus described my invention, what I claim is An annealing box having unitary sides,- ends, and top, corrugations extendin upwardly along said sides and across sai l top, a corrugation extending upwardly along said ends and longitudinally along said top so as to intersect said first named corrugations, reinforcing members in said corrugations and retaining ears spaced alongside said corrugations and overlapping said reinforcing means so as to hold said means in place.
In testimony whereof, I have hereunto subscribed my name this 17th day of Decene ber, 1923.
FRANCIS H.,\CLAY.
