'This invention relates-to the formingand'lay- 'ing of building blocks, and has for its object "to providethe forming of a block with one horizontal surface longer than the parallel surface "of the opposite side of the block, and ilatnng these blocks into walls so that one block, with its longer side down," bordered on'both ends by blocks with their longer sides up, thus the joints made between the "ends of the "blocks are sloped from the vertical in oppositedirections.

In order that the ends and corners of walls may 'be'made vertical and th'at'the openings in walls may have vertical sides some of the blocks are formed of one sloping end and one end at right angles to thehorizontal .sides. has cores within and one or two semi-cores at ends of the blocks, and when "laid together such ends form complete cores these along with the complete .below'in the wall.

'Some whole blocks and some halt blocks are formed with no semi-cores at the vertical ends. These are used where the ends ofthe blocksform vpart'o'i the wall surface.

The blocks are laid into walls in very much the same manner as ordinary blocks so'that'the joints between the'ends of theblocks on a lower tiermeet close to the center of the blocksucomlprising the tier above. I

The primary advantages of my block over those in other constructions is that the wedge shape of the blocks when they are placed into a wall allow for horizontal distribution of strain to the left and to the right, as well as transmitting pressure downward. Thus pressure is distributed horizontally and vertically. These actions not only press or squeeze the motor tightly between the tiers of blocks, as ordinary blocks do, but the motor is held firmly under pressure while it is setting between ends of the blocks. This makes for firmer, tighter bonds between all surfaces of the blocks where they meet. Concentrated loads, such as beams, placed upon the walls constructed of my blocks are carried by a greater number of blocks than by using ordinary blocks. This is accomplished because of the wedge shape of the block structures. The load placed on one block is not only transferred to an ordinary pyramid of blocks below but the load is also distributed horizontally as well, and a greater pyramid support for the load is provided. I

A further object of this invention is to provide a new method of concrete block structure and building of walls so that the weight of the wall,

This distribution carries pressure or strain over a greater number, or into the greater number,

"of blocks than is possible with normal type of structure. This is made possible due to the inherent form of my concrete'bloeks in'whichthe "ends are not vertical or at right angles to the horizontal "sides" and walls.

These and many other objects I accomplish with the device illustrated in the accompanying drawings in which similar numeralsand'letters of reference indicate like parts throughout the in the specification fforming I8, .part of this application and :pointed out in the; appended claims.

In the drawings Figure l-is an elevation partly in section of a wall formed with my'blocks.

perspective and shows how the blocks interlock and overlap. v

Figure 6 is a perspective view ofv a full length block with one end made without a core and shows the semi or partial cored opposite end.

In the drawings in which I have shown my blocks, the blocks are shown as A, B, and C. The blocks A being those blocks which are formed with one end vertical, or at right angles to the horizontal planes on top and bottom, and with one end at a slope thereto, or at an acute angle with the longer side. The blocks B are end views of blocks forming parts of the wall surface. The blocks C are the blocks which really constitute the principle of this invention, in which the top and bottom are parallel and the two ends slope in opposite directions.

All the blocks are provided with vertical cores, or core openings for the usual purposes in concrete or composition blocks for ventilation, pipe installation and other like features.

The half block B as shown in Figure 3 of the drawings is used in construction where the end gt the block does not form a part of the wall surace.

The block A is formed with the top and bottom surfaces 5 and 6 parallel to each other and with one end 1 at right angles to the top and bottom surfaces, the other end of the block 8 forms an obtuse angle, as considered with the shorter horizontal surface, or forms an acute angle with the longer side and has a partial core, or opening, 9 therethru, as shown in Figure 6 of the drawin s.

'I'he block B is of a like form except that it is a short block for use in construction where the vertical end forms part of the wall surface and where a half block is needed.

The block C consists of a flat surface I? and fiat surface is with the ends of this blocl: I l and I5 sloping toward each other when viewed in relation to the shorter side shown in Figure 4 of the drawings. This block is provided with the usual vertical cores l7 separated by webs l8 and with the end half cores, as shown in the drawings at iii.

When the blocks are laid into walls, the cores within the blocks and the matched partial cores at the ends of the blocks are aligned with the cores of blocks in tiers above and beiow in such a manner that the edges of inner webs substantially overlie the horizontal junction lines of ad jacent blocks thereunder, as may best be seen in Figure l. The planes of adjacent end faces of succeeding blocks diagonally intersect he inner webs of overlying and underlying blocks providing a cleavage plane in the webs of a length substantially greater than the thickness of the webs.

Having thus described my invention I claim:

1. A wall composed of layers of cored blocks in superposed relation, said blocks having horizontally disposed top and bottom surfaces and having end faces disposed in converging planes at acute angles from verticality, succeeding blocks in a layer being respectively reversely disposed so that the planes of adjacent end faces are parallel, said blocks being vertically cored to provide in each block a plurality of vertical passageways defined by vertical side Walls and by transverse webs perpendicular thereto, said ends of said blocks being partially cored so that said vertical side walls extend triangularly beyond the outermost Webs to form with the corresponding side walls and webs of adjacent blocks vertical passageways between adjacent blocks, succeeding layers of blocks being so arranged that said passageways are axially aligned and extend unintercores cut diagonally to form ruptedly through said wall, said succeeding layers being further so arranged that edges of inner Webs substantially overlie the horizontal junction lines of adjacent blocks thereunder whereby the planes of adjacent end faces diagonally intersect the said inner webs.

2. A wall composed of layers of cored blocks in superposed relation, said blocks having horizontally disposed top and bottom surfaces and having vertical side walls in the shape of isosceles trapezoids, successive blocks in a layer being relatively reversely disposed so that long edges of said trapezoids alternate with short edges in a horizontal line, said blocks being vertically cored to provide in each block a plurality of vertical passageways defined by said vertical side walls and by transverse webs joining said side walls, angular ends on said blocks, said ends being partially cored so that said vertical side walls extend triangularly beyond the outermost webs to form with the corresponding side walls and webs of adjacent blocks vertical passageways between adjacent blocks, succeeding layers of blocks be,- ing so arranged that said passageways are axially aligned and extend uninterruptedly through said wall, said succeeding layers being further so arranged that edges of inner webs substantially overlie the horizontal junction lines of adjacent blocks thereunder whereby the planes of adjacent end faces diagonally intersect the said inner webs, to provide a cleavage plane in the webs of a length substantially greater than the thickness of said webs.
