UNITED {Sr-Arse We OFFICE FABRICA'IED METAL CONTAINER Paul S Menough, Rocky River, Ohio Application December 30, 1950;Serial No; 203,625
in furnaces, and is more particularly concerned with a unique annealing boxintended tostand on top of such trays and to enclose and maintain v in position bulk loads carriedby the trays. Conventional boxes for use with annealing trays are either one piece castings or made up of several cast pieces which are hinged togeth'er at the corners by means of lugs andpin's. In either case, the box is subject to failure and soon fails in use because of the temperature shocks'to which it is subjected. Most commonly this failure takes the form of breaks a't'theeorners where the box is subject to the greatest stress due to rapid expansion or contraction resulting from these shocks. This shortcomingof the conventional devices has been endured because attempts heretofore to avoid it have resulted only in more serious difliculties. According to one proposal, forexample, these boxes would be constructed of such thin section that I so weak that they will not retain their shapes,
particularly when they are in the hot zone of an annealing line.
It is accordingly a primary object of this invention to provide an annealing box which is both as strong as necessary for the conventional use aforementioned and is also entirely free from the failure tendencies of the prior art devices, and particularly corner structure failure, attributable to thermal shocks involved in ordinary use. 1
It is a further object of this invention to provide an annealing box which has substantially longer useful life than any annealing box heretofore known. i
It is another object of my present invention to provide an annealing box combinin unusual flexibility characteristics with strength and resistance to forces tending to deform the device, whereby the box may yield under forces which would break heretofore conventional boxes and yet will withstand these same forces to prevent deformation of the box beyond the point where it can serve its intended purpose and also return to its original shape when the stresses are relieved. r I
than said prior art devices.
. It-is-a further object of-my invention to prov-ideanannealing box which is free from the foregoing shortcomings of the prior art and yet is made of high alloy steels. v
"It isstill another object of my invention to provide annealing boxes Which are lighter and easier to handle than those of the prior art and which require substantially less maintenance It is still'a further object of this invention to provide annealing boxes which are readily made with a mini-mum number of "simple and relatively inexpensive parts without requiring elaborate special equipment or sk-iils whereby the cost of these boxes may bemaintained at a minimum comparing favorably with the cost ofany heretofore conventional and commercial devices of "this type. V
lh'ose skilled in the art will gain a further understandingof this invention and of the additional objectsand advantages of this invention upon consideration of the following detailed description, taken inconiunction with the drawings accompanying and forming a part of this specification, which: 7
Fig; 1 is--a perspective view of an annealing tray and abox embodying this invention in a preferred form, the box being in the normal position with respect to the annealing tray to maintain the tray load in place;
Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1, showing the relative positions of the tie members and the end wall membersnf thebox;
Fig. 3 is a fragmentary, perspective view of another box embodying this invention, parts being broken away toshown the form and relationship of several elements-of the box; and,
Fig.4 is a vertical, sectional view taken on line 4--4 of Fig.3.
Generally, :a device embodying this invention comprises-a pair of metal sheets which are spaced apart to constitute opposed walls of a box, and a'second .pair of sheet metal elements spaced apart, opposed and located between the first pair and cooperating with them to define a foursided open vessel. All four sheets of this assembly are movable within predetermined limits relative'to each other and means are provided comprising a plurality of tie members extendin between and connecting the first pair of sheets for maintainin the assembled sheets in position relativeto each other within the aforesaid predetermined limits. These tie members are arranged 55 in two groups which'are spaced apart and one of dividual tie members of one group while the other sheet is similarly related to the ties of the other group.
More particularly and with reference to the foregoing drawings, a typical box 3 of this invention comprises two corrugated metal sheets H] of substantially the same dimensions, these sheets being spaced apart and opposed to define the side walls of the box. The box end walls are defined by a pair of corrugated sheets 12, suitably of the same stock as the sheets Ill but cut into shorter lengths and disposed between and at substantially right angles to sheets 10 and bearing against said sheets adjacent to the ends thereof to define an open-ended box. The corners of this box thus are open between points of engagement of the corrugations of sheets Ill and 12. The upper and lower edge portions of sheets and [2 are in two substantially parallel common planes so that the boxmay be placed upright on an annealing tray T to enclose and stabilize in position on tray T a typical load of a number of metal parts to be annealed.
Box B is held together and. in shape by means of twelve tie rods 14 arranged in two groups of six disposed at each end of the box. Tie rods I l are arranged in pairs at the upper, the intermediate and the lower portions of the box and are nested in adjacent corrugations of sheets I2. Tie rods I l extend through holes provided for the purpose in the end portions of sheets l0 and are retained in place by means of enlarged portions or heads which are provided at the extremities of the rods 14 to engage the outside surfaces of sheets l0. Preferably, the tie rods are not welded to the side wall sheetsor to the end wall sheets, but are spaced from but engageable loosely with the side wall sheets and likewise heads [5 normally engage the outside surfaces of sheets I2 only part of the time. Thus in the preferred embodiment of this invention, the tie rods are of a slightly greater free length between heads I5 than necessary to assure constant firm engagement of sheets [Band I2 with each other. This arrangement permits expansion of sheets 12 without the creation of stresses in them, or in sheets 10, or in the tie rods. This result, of course, may be obtained regardless of the manner in which the tie rods are headed, the free or effective length of these rods between their heads being the controlling factor.
With reference to Figs. 3 and 4, the box illustrated is generally similar to that of Figs. 1 and 2 and comprises two, spaced, opposed corrugated metal sheets In constituting the side walls of the box, a pair of spaced, opposed, corrugated metal sheets l2 constituting the ends thereof and means for holding the sheets in their assembled position while allowing relative movement of the sheets within predetermined limits, as set out above. This means comprises six tie rods [4 having head portions [5 and being related to the sheets [0 as described above. These tie rods M, however, are disposed only on the inside of the box being nested in spaced corrugations of the end wall sheets l2. On the outer sides of these end wall sheets tie rods 20 having head portions 2! similar to heads [5 are provided, being nested in corrugations adjacent to those in which tie rods 14 are disposed on the opposite sides of sheets l2. Tie rods 26 differ from tie rods l5 essentially in that while the former are rods or bars of substantially uniform diameter, the latter are of generally U-shape except at their ends where they are tapered into substantially cylindrical round form so that they may be used interchangeably with rods Hi to pass through the openings provided for rods i l in the side wall sheets l0. Thus, the longitudinally extending edge portions of U-shaped parts of a typical rod 20 bear against the upward slopes or sides of a corrugation valley, as indicated in Fig. 4. By virtue of this construction, the tendency of the end wall sheets IE to bulge outwardly under pressure applied as the tray and its box are pushed through the furnace with the end walls extending parallel to the direction of travel is overcome and undesirable distortion of the box is prevented.
It will be understood from the foregoing description that both the illustrated embodiments of this invention will aiford all the advantages over the art stated above, and will meet all the foregoing objectives of this invention. It will also be clear that these boxes of my invention may be used as easily as those of the prior art, and probably more easily because of their unusually light weight. Furthermore, these devices of mine are not open to a sufficient degree at their corners that the chimney effect usually desired in annealing boxes is diminished to any objectionable or even noticeable extent. Surprisingly, it is even possible to employ the boxes of this invention in the heat treating of white cast iron parts Without distorting, warping or deforming these boxes in any way. In accordance with the prior art, special precautions had to be taken with respect to white cast iron parts to prevent any or all of these results because of .the well-known permanent expansion characteristic of this metal. I
Having thus described the present invention so that those skilled in the art may be able to gain a better understanding and practice the same, I state that what I desire to secure by Letters Patent is defined in what is claimed.
