MELVIN K. MORRIS BY ATTORNEY United States Patent 3,154,391 INGGT Melvin K. Morris, New Martinsville, W. Va, assignor to Ormet Corporation, a corporation of Delaware Filed Sept. 27, 1%2, Ser. No. 226,676 4 Claims. (Ci. 29-184) This invention relates to ingots and more particularly to cast ingots provided with interlocking means for engagement with similar ingots adapting them for assembly in a stable stack.

Accordingly, it is an object of this invention to provide ingots of novel construction adapting them for assembly into a stable stack or bundle.

It is another object of this invention to provide an ingot with novel interlocking means for interlocking engagement with like means provided on similar and adjacent ingots.

A further object of this invention is to provide interlocking similar ingots which upon assembly provide a rigid layer resistant against longitudinal and lateral movements.

A still further object of this invention is to provide ingots adapted to be secured together in interlocked engagement to provide a stable layer of ingots as a platform for succeeding ingot layers.

Other objects and advantages of this invention will become more apparent from the following description and drawings in which:

FIGURE 1 is a plane view illustrating an ingot in accordance with this invention;

FIGURE 2 is an elevational view of one side of the ingot illustrated in FIGURE 1;

FIGURE 3 is an elevational view illustrating the opposite side of the ingot of FIGURE 1;

FIGURE 4 is an elevational end view of the ingot shown in FIGURE 1;

FIGURE 5 is a cross-sectional view taken along lines VV of FIGURE 2; and

FIGURE 6 is an end elevational view of an assembled stack comprised of the ingot shown in the preceding figures.

The ingot 1 illustrated in the drawings is characterized as a cast bar or pig 2 of metal, such as aluminum and the like, generally of quadrilateral cross-section and having slanted or

oblique side walls

3 and 4 intermediate the upper surface 5 and lower surface 6. Each of

side walls

3 and 4 has laterally projecting therefrom, adjacent the lower surface 6, a pair of flanges or

berms

7 and 8, respectively, one having a configuration complementary of the other. Each of the berms will have their surfaces complementary to the other and may be generally described as bowed relative to the upper and lower bar surfaces, with the upper berm surfaces 9 and 10 further characterized by being angled, generally acute, relative to the bar side walls to thus define compound angle therewith.

In the embodiment illustrated, the upper berm surface 9, of berm 7, is substantially planar and symmetrically slanted downwardly toward the lower bar surface 6 from a high point 11 relative to the upper bar surface 5 at the mid-point or center 12 of berm 7. In addition, the berm surface 9 is slanted downwardly from its lateral edge toward the bar side wall 3. Although the upper surface 9 of berm 7 has been illustrated as of angled configuration, it is to be understood that other configurations may also be employed as for example an arched configuration provided that a complementary configuration i-s defined by the upper surface ill of berm 8.

With regard to the particular embodiment illustrated, the upper surface ill of berm 8 is provided with a conice figuration complementary to the upper surface 9 of berm 7. As shown in the drawings, the upper surface 10 of berm 8 is substantially planar and symmetrically slanted upwardly toward the upper bar surface 5 from a low point 14 at the mid-point 15 of berm 8, with the upper berm surface it further defining an angle with the bar side wall 4 identical to the above angle 13. Accordingly, the upper surface ll of berm 3 also defines a compound tangle wtih the bar side wall 4. As indicated above the upper surface 10 of berm 8 may take other configurations than the specific angle embodiment illustrated in FIGURE 3, as for example an arched configuration provided that it is complementary to the configuration defined by upper surface 9 of berm 7.

This construction in a plurality of ingots adapts each of the ingots for interlocking engagement with similar ingots disposed in side-by-side relationship in the same layer of a stack with, as illustrated in FIGURE 6, the berm 8 of an ingot 1 meshing with a complementary berm 7 of a configuration corresponding to berm '7 provided on an adjacent ingot 1' whereby the complementary configurations of adjacent ingots enables their assembly together in a nesting relationship. The bowed configuration of the upper berm surfaces when meshed with complementary surfaces of adjacent ingots results in an arrangement which is resistant to longitudinal displacement of the ingots while, in conjunction, the com- .pound angles defined by the upper berm surfaces and the side walls of the adjacent ingots provides an arrangement resistant against lateral displacement of the ingots. As a result, a layer of ingots when disposed in interlocked engagement with one another provides a very stable and firm platform for supporting succeeding layers of ingots disposed thereon. As illustrated in FIG- URE 6, each succeeding layer of ingots is generally disposed at right angles to the preceding layer. When sufiicient layers of the bars have been assembled to the desired stack height, the assembly may then be secured together by appropriate and conventional banding for handling and transport.

Although the invention has been described with reference to specific embodiments, materials and details, various modifications and changes, within the scope of this invention, will be apparent to one skilled in the art, and are contemplated to be embraced within the invention.
