This invention relates to improvements building blocks.

One of the main objects of this invention is to provide a form of building block which is arranged so that a group of such blocks can be easily set in position for building a Wall, a roof, and the like, and the blocks will interengage in such a manner as to provide a complete, unitary and air tight construction, the blocks being held securely together without any additional fastening means. A further object of this invention is to provide a set of relatively thin or slab-like building blocks which are adapted to beset upright in building a wall, or in forming the outside nishing layer of a Wall or the like, and which have interengaging means provided on their edges, so that the blocks can be readilypressed down in position and will then be held securely together, to prevent relative movement between the blocks in a direction outwardly of the wall and likewise longitudinally of the wall.

A more specific object of this'invention is to provide such a building block which can be readily set in place and wherein the blocks are rmly engaging tongue and groove means on their edges, serving to form an air tight wall and to prevent relative movement between the blocks transversely thereof, and which have anchoring means to prevent the blocks from separating laterally from each other.

These and various other objects and advantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawing wherein this invention is shown in a fewof its various forms of construction, it being apparent that various other forms and modifications may be resorted to for carrying out the objects' and purposes of this invention.

In the drawing:

Fig. 12 is an elevational view of two interconnected blocks showing a modified form of anchoring means thereon.

Fig. 13 discloses another modied form, of two aring wings.

Brieiiy, these blocks are shaped so as to be easily set in place in building the walls and the roof of a house, garage, silo, and the like. They are provided with interengaging means on the edges to form a firm and 'air-tight connection. They also have anchoring means, such as aring wings, or lugs and notches, and the like, for preventing separation lengthwise of the block; and these wings diverge outwardly from a central stem as shown in Fig. 3, or from a central axis, as shown-in Fig. 13, thereby tending to draw the blocks together.

The blocks may be constructed with a plurality of layers secured together, as best shown in Figs. 5 and 7, and they may be made solid, as shown in- Fig. 6, by casting or molding the s ame. They may consist of tile, metal, plasterboard, Celotex, and the like.

In the form illustrated in Figs. 1 to 5 inclusive, the block I I is relatively thin or slab-like, and is constructed from three layers, two outer layers I2 and I2' and an intermediate layer I3 therebetween. The block includes a main bar or stem portion I4 having its side edges substantially parallel; and having wings I5 extending laterally in opposite directions from the stem.

The blocks are provided with tongue means I6 and groove means I1 on opposite edges. For this purpose the layers I2, I2', and I3 are preferably made substantially alike in shape and size and are secured together so that the intermediate layer I3 overlaps or projects beyond the outer layers I2 and I2', around one-half of the edge of the block; while around the other half of the edge of the block the outer layers I2 and I2 overlap the' intermediate layer I3, as illustrated.

The block is then placed so the tongue means is on the upper edge of the block for receiving the `groove means on the lower edge of the succeeding block, being thus adapted to' shed moisture outwardly of the Wall.

In this form of construction the wings I5 are flared outwardly to be broadest at the outer end I5', being substantially dove-tailed in shape, and thereby provide anchoring means to prevent separation of the blocks laterally of the wall, the blocks being positioned upright and joined edge to edge, as indicated in Fig. 1.

As illustrated in Fig. 4, I also provide half blocks 2l including a main stem portion 24 from which an outwardly flaring wing 25 extends laterally, the block includes upper tongue means 26 and lower groove means 21, as in the preceding form. This block is adapted for use at the edges bf the wall and at the door frame, and the like.

For use at the corners of a building these blocks are also made in angular form, as indicated by block 3| in Figs. 8 and 9. It may be constructed substantially like the form shown in Fig. 3, and includes a stem 34 and outwardly aring wings 35 extending laterally therefrom. It is bent at the longitudinal center line of stem 34 to provide the desired angle at the corner of a building. This block, likev the preceding ones, has tongue means 36 at its upper end and at one side, and has groove means 31 at the lower end and at the side opposite to the tongue means, to

cooperate with corresponding groove and tongue v means on the adjoining blocks.

As illustrated in Figs. 10 and 11 the blocks will also be made curved for constructing curved walls, in building silos, catch basins and the like. This block 4I includes a main stem 44 and outwardly aring wings extending in opposite directions therefrom, the block being provided with upper tongue means 46 and lower groove means 41, as in the above described blocks. y

My improved block may consist of several layers united, as stated above, and may also be made of an integral construction, as by casting or molding it, as indicated by block 5I in Fig. 6. Such block is provided with tongue means 56 and groove means 51 at its opposite edges, in the manner described above.

As indicated by block 6I in Fig. '7, the block may be provided with a plurality of tongues 66 at one part and a plurality of grooves 61 at the opposite part. This may be accomplished by constructing the block from a plurality of layers and hav- -ing the alternating layers overlap or project at the opposite edges of the block,to provide the tongue means and groove means, as indicated.

Fig. 12 illustrates another modified form of block. Herein the block 1I includes the main sternV 14 which is preferably positioned vertically in the wall and includes wings 'I5 extending laterally in opposite directions from the stem.`

Tongue means 16 are provided half way around the edge of the block, and groove means 11 around the other half of the block, like in the preceding form. In this form the wings 15, as well` as the stern 14, have their opposite sides arranged parallel; but different anchoring means is provided. Herein the anchoring means includes a lug 18 provided on the edge of'one part of the block. and a notch 19 provided in the edge on the opposite part of the block for receiving the lug of an adjoining block.

In Fig. 13 a further modified form of block 8| is shown. It consists of two flaring wings 85 which diverge from each other or from a vertical central axis, instead of diverging from a central body or stem, as in the preceding forms. It also has tongue means 86 provided on its edge, half way around the block, and groove means 81 around the opposite half, to provide for a rm interlocking connection between the blocks'.

My improved block, in either of its forms of construction, can easily beset in position in constructing a wall and the like, and, due to the dovetailed or flaring side wings, the blocks can be readily pressed down and slid tightly together into rm interlocking position with the blocks of the preceding row. 'Ihe blocks are set in position to have the tongue means placed upwardly in the construction, in order to shed the rain and moisture outwardly. 'I'he dove-tailed or iiaring arrangement of the wings serves to slide the blocks tightly together and also serves as anchoring means for preventing separation of the blocks in the direction longitudinally of the Wall; and the interengaging tongue and groove means prevents separation of the blocks transversely thereof or outwardly of the Wall, and also provides an air tight and weather-tight construction. 'I'his interengagingy and interlocking arrangement also produces a flrm connection between the blocks and a relatively rigid wall structure, without the use of any special securing means for holding the blocks together, and very little or no special frame means or bracing means is required with this improved lblock, in the small structure for which it is intended. l

When the blocks are of metal or wood, they are usually painted, and the paint will serve also as sealing means for fully sealing any possible crevices that may exist at the junctures of the blocks. When the blocks are of tile or cement, then any liquid coloring or coating applied to the surface thereof will likewise serve as sealing means, or the joining edges of the blocks may have a cementitious grout applied thereto to provide a positively sealed connection.

I claim:

1. A slab-like building block consisting of a plurality of superposed layers of material, one layer of which protrudes beyond the adjoining layer continuously for one-half way around the edge of the block, and recedes continuously for the other half way, thereby providing tongue means on half the perimeter and groove means on the other half of the perimeter of the -block to interengage with corresponding groove and tongue means on the perimeter of the adjoining blocks tto prevent relative movement in one direction,

` andaring means on said blocks including their tongue and groove means to prevent separation thereof in another direction.

2. A slab-like building block comprising a main upright and to be readily set down in position upon similar blocks in a construction, dove-tail wings extending laterally in opposite directions from said stem adapted to hold the blocks against separation laterally, and tongue and groove means extending entirely around the edges of the wings and stem, to interengage with and to closely t corresponding groove and tongue means extend- Ving around the edges of similar adjoining blocks, whereby to secure the blocks together and to provide a rigid and substantially air-tight construction.
