INTERLOCKING MULTIPLE BRICK.

Application filed JuneY, 1923. Serial No. 643,861.

To all whom it may concern Multiple Bricks, of which the following is a specification. r

This lnventlon relates to building blocks, more especially to blocks. such as may be formed of concrete or other suitable material, each block being preferably formed to simulate a plurality of bricks or other building units and each block extending prefer-' ably across the entire thickness of the wall, the several blocks forming when laid a securely interlocked construction of great strength and rigidity.

It also provides a construction whereby, if desired, the wall may be laid dry and the cement then forced between the blocks through openings in the rear face of the wall. r

For a more complete understanding of this invention reference may be had to the accompanying drawings in which Figures 1', 2, and 3 are isometric views of certain formsof blocks which are preferably used in combination in building a wall.

Figure 4 is a rear elevation ofthe form of block shown in Figure 2.

Figure 5 is a section on line 5 -5of Figure 3. 7

Figure 6 is a view similar 1 1* Figure ,4, but showing a different face pattern. 4

Figures 7 and 8 are isometric views showing the wall in different stages of. construction. i V

Figure 9is a similar isometricview showing a modification.

In its preferred form, three different forms of blocks are used in making the wall as above noted, though any one of these forms may be used alone, if desired, to con struct a wall which is not interlocked vertically between the courses. One of these forms of block is shown in Figure 1. It comprises a substantially flat block of a width equal to the thickness of the wall desired and preferably having its sides formed to simulate a plurality of rectangular building units such as bricks. These are shown at 1 in this figure. noted that both end faces of this block terminate in marginal surface portions 2 and 3 which are in parallel planes ofiset from It will be surfaces are joined by a diagonal surface l which is cut back from the face 3 as shown at 5 for a purpose which; will later appear. The blocks are thicker adjacent their mar ginal portions as shown at 6 than intermediate thereof forming a depressed portion 1 as at 7 and the edges ofthe thicker portions are formed to simulate the joints be tween successive tiers of bricks. The-deeach other lengthwise of the block and these pressed portions 7 serve to receive cement by which the blocks are bondedtogether as will later appear. Centrally through.

the block between its top and bottom faces are openings 8 and surrounding the-mar gins of these openings are grooves 9 extending in closed paths therearoulnd and communicating with the back surface ofthe block through a notch or groove 10. In the preferred construction this block is only a filler block and is not, used except in the uppermost and lowermost courses of the wall. I a

The main blocks are illustrated in Figures 2 and 3 in which it will be noted that they are double the thickness of the block shown in Figure 1 and represent a pair of superposed courses of bricks, a pair of bricks being shown in each course as at 11, break- The upper and ing joints with each other. lower portions of the front and rear faces of the blocks are thus staggered horizontally and in opposite directions and the ends of. the block assume a stepped formation 1m; ing faces 12 and 13 in different parallel planes, the faces 12 at each end of the block being in the same plane and the'faces 13 also being in the same plane these faces being in reversed relation to the upper and lower surfaces adjacent opposite faces of the wall. These faces are joined by, the, diag onal faces 14; which are inclined in opposite directions and which are set back from the faces 13 by the portions 15. Theseblocks are also provided with vertically extended openings 18 therethrough with surrounding marginal grooves '19 and a groove 2000mmunicating therewith an opening at the rear face of the block. a

The block shown in Figure 3 is similar face of the block while in the form shown in Figure 2 the correspondingjface 12 is in the lower course at the right hand end. Otherwise the blocks 2 and 3 are similar. For convenience in referring to these blocks when built into the wall the form shown in Figure 2 may be designated as an A block,

the form shown in Figure 3 as the B block,

the form shown in Figure 1 as the 0 block.

- portion of the block, these maybe filled with cement when the blocks are laid and present a completely finished apearance similar to the forward face.

Referring to Figures 7 and 8 which 5110 ws the preferred manner of laying the blocks, it will be seen that a O block is laid, adjacent thereto end to end an A block. The face 13 of the A block in the upper tier overlaps the upper face of the 0 block, as shown, and at the rear face of the wall the face 13 butts against the end face of the C block, a space 35 being left between their abutting end faces at;the front and rear of the wall for the reception of cement. C and A blocks are laid in succession in this manner throughout the length of the wall as shown 7 in Figure 7 Next the B blocks are superposed on theO blocks, as shown in Figure 8. The end face 12' of the B block butts against the end face 13 ofthe A block over- I lying the C block, the lower course of brick simulating portions being in the same plane as the upper course of the A block, while the faces 13', of the B block overlie the end portions of the A block adjacent to the faces 13, the upper courseof brick simulating portions of the B block being above the upper course of the A block. The B blocks are thus placed in the openings between the A blocks and extend over or lap the A blocks at their ends throughout the length of this course. Next a row of A blocks is laid in the spaces between the B blocks, their ends extending over or lapping the ends of-the B blocks, and so on until the wall is at the desired height, the B blocks forming thefinal course. The blocks A and B therefore lie at different elevations the lowerbrick simulating course of one facing the horizontal continuation of the upper brick simulating course of the other. C blocks are then placed between the final row of B blocks which serve to finish the top of the wall flush. Of course if it should be So desired, blocks similar to the 0 blocks but having their end faces inclined oppositely thereto,,might be employed in case it were desired to start or finish the wall with B blocks for the last course instead of A blocks.

The wall may be laid up dry, if desired, and give the appearance of bricks with joints therebetween. Cement in the form of grout may then be forced between the blocks through the notches 20 so that when set the wall becomes a monolithic mass. Of course, if desired, the blocks may be laid up in the ordinary manner with mortar or cement. It

will be noted that this construction of blocks effects an interlock both laterally of the wall and vertically, each course being bounded with the courses above and below by the interfitting end portions of the various courses. I y

, In Figure 9 is shown the manner of using the blocks in which only one form is re. quired, either the A or B blocks. In the embodiment shown B blocks are employed. These are laid in courses, the ends of the blocks interfitting and overlapping in inter locking relation, but it will be noted that each course of blocks is entirely in one plane so that there is no interlock between the superposed courses of blocks. A or even C blocks could be laidin the same way but the C blocks wouldrhave little latteral interlock. In Figures 7, 8 and 9, the forward faces of alternate blocks are shown shaded in order that their relative positions may be seen. It should be understood, however, that in practice they are preferably all alike so that no visible demarcations of the individual blocks appear.

Having thus described an embodimentof this invention it should be evident that various changes and modifications may be made therein without departing from its spirit or scope as defined by the appended claims.

I claim:

1. A block having its faces at its ends presenting step formations, the step formation adjacent to opposite side faces at the same end being reversed, and end faces inclined in reverse directions in the upper and lower portions of the block joining said step formations, said inclined faces being set inwardly from said step formations thus to provide a pair of diagonally arranged pro jecting portions at each end of said block, said projecting portions at opposite ends being of substantially the same size.

2. A wall comprising a plurality of' units, each of certain of said units having a portion in the same-plane withand mating a portion of an adjacent unit, and a portion in a different plane and lapping past said other unit, the lappingportions being alternately at opposite side faces of the wall.

3. A wall comprising blocks, certain of said blocks being of one-half the vertical thickness of the remaining blocks and having projecting end portions, the projecting portion at one end being adjacent to one side face and the projecting portion at the other end being adjacent to the opposite side face, the remainder of such blocks each having a pair of projecting portions at each end, each of one-half the vertical thickness of the blockand the two arranged adjacent to opposite side faces thereof, said full thickness blocks in the wall being arranged end to end, adjacent blocks being at different horizontal levels, the projections of one fitting between the projections ofothers, and said half thickness blocks filling in the spaces between non-adjacent blocks on the same horizontal level at the top and bottom of the wall.

4. A wall comprising blocks certain of said blocks being of less vertical thickness than the remaining blocks, said remaining blocks being laid end to end out of honzontal alinement and having their ends formed to interlock with each other, and said thinner blocks being laid between nonadjacent thicker blocks and presenting therewith horizontal upper and lower faces for said wall.

In testimony whereof I have a'tfixed my signature.
