When the end wall is now permitted to settle under the action of gravity, it moves downward and toward the side walls, under the controlling influence of the engaging surfaces l1 and 23, until the bottom edge of the end wall rests upon the bottom slab and the faces of the groove 25 have contacted the faces of the ridge l8. When both end walls have been thus assembled with the side walls, the cover slab 2B is placed in position. As shown, it is made in three sections and rests loosely upon the side and end walls. Whether the cover is made in one piece or in two or more sections, and whether it rests loosely upon the box walls or is provided with some means for preventing lateral displacement, is, of course, entirely a matter of structural design and preference to meet a given set of condltions. Similarly, means may be provided, if deemed desirable or necessary, to prevent lateral displacement of the walls of the box with respect to the bottom slab ll.
When the bottom, walls, and top are assembled as shown, it is apparent that the weight of the ends, the: cover, and earth or other material on top of the cover, tends to force the end wall into closecontact with the ends of the side walls and to lock the end wall against horizontal displacement either outwardly away from the ends of the side walls or transversely of the ends of the side walls. The interlocking faces 23 and I5 are the means by which this weight prevents the former displacement, and it is by the combined faces and of the mating groove 25 and tongue l8 that this weight is effective to prevent the latter displacement.
The essence of our invention is the interlocking joint so constructed that, when in proper position, the weight of one of the joined members -and have so referred out departing tends to hold that member against displacement horizontally in any direction with respect to the other member. While we have described the joined elements or members as vertically disposed, to them in the claims, we wish it understood that this is for convenience and brevity. of description only, and that if either or both of the joined members are disposed in any'position between the horizontal and vertical, it is still possible that a component of the force of gravity acting upon the mass of one of the members may be effective to hold the joined members in locked relationship. Even if one of the members is disposed horizontally, it is possible for some force other than gravity to act to hold the joined members in interlocked relationship.
It will be apparent that many changes can be made in the details of construction of the embodiment of our invention described above withfrom the principles thereof. For example, the bottom slab, for convenience of handling, may be made of a plurality of sections. The grooves 25 and mating ridges l8 may be of arcuate, rectangular, or other outline in cross-section, instead of V-shaped as shown and described herein.
While we have described and shown one embodiment of our invention, we desire not tobe limited to this embodiment, but define and set forth our invention in the following claims.
