- .WALL-CONSTRUCTIOliT MATERIALJ application filed April 11, 1927. Serial 'No. 182,821.

My invention relates to improvements in wall construction materials which. are particularly directed to hollow wall, construction and to the provision of means whereby the various vertical structures of the wall are laterally bonded together by tie blocks which extend from one wall block to another for the purpose of providing a means wherein continuous longitudinal reinfo w:e nent may be built into the wall and for the purpose of forming a wall of great strength and light ness of weight. V The invention consists essentially of a plurality of blocks having one or more of their side edges constructed to interlock with other blocks provided with side edges correspond ing in shape thereto, as will be more fully described in the following specification, in which: p V

Fig. 1 is a perspective view showing a section of wall constructed according to the in-' vention.

Fig. 2 is a perspective view of a section of wall construction showing an external angle.

Fig. 3 is a perspective view of an interior stretcher block.

Fig. tis a perspective view of an interior tie block. r

' Fig. 5 is a perspective view of a face stretcher block.

Fig. 6 is a filler block. r

Fig. 7 is a modified form of block section.

In the drawings like characters of reference indicate corresponding parts in each figure.

The numeral 1 indicates generally a stretcher block, see Figure 3, such as would be used in the interior of a wall corresponding to a three horizontal course wall of regular construction, the block is preferably formed with a longitudinal groove or frog 2 in its upper and lower faces, either ofwhich may be effectively utilized for the purpose of housing a reinforcing rod 3 which would be embedded in mortar or cement to form a bond longitudinally of the courses where deemed expedient, such as over door and window openings and the like. The side faces of the block are formed with vertical portions 4 and 5 which are separated by an interlocking mould 6 consisting of a tongue 7 and a groove 8. I

The face stretcher blocks see Figure 5, are indicated by the numeral9, which blocks are provided with one moulded side face similar perspective view of an end to those. on the interior stretcher blocks l, the other face be ng afplain vertical surface lllsuitable forfeither exterior facing of a bu ldi-ji'ig or forplastering or interior facing;

,ne stretchers 'lyand 9 are laid longitudi' n'allyflof the avail and are spaced apart as shown in Figuresl and 2,'the different divisions of. stretchers being connected together by blocks 1 1, which tie 'blocks are provided with moulded faces 12 corresponding to those of the blocks 1 and 9, so that the tongues, and grooves of the tie blocks will interlock with the 'sin' ilai parts of the stretchers 1 and 9, with the result that a hollow wall is formed wherein the stretchers l and 9. are bonded together through face contact by the tie blocks 11. If great strength is not required in the walls, the tie blocks 11 need only be applied to alternate courses, thus savingv a considerable amount "ofbluilding material. Where a face stretcher block 9 is brought to the, end of a wall or to an outside angle of intersecting walls, such is shown in Figure '2, a filler block '13, 'wh eh is provided with a, plain vertical face 14 and a tongued and grooved face 15 but which has a total width equal to one half only of the tie blocks, is provided, so that the coi'nbined end face of a face stretcher 9 and a fillerl3 will form a rectangle having an inner vertical face against which the end of a further face stretcher 9 may abut neatly at 16, see Figure 2.

A modified form of block is indicated by the numeral 17, see igure 7 in which an interlocking tongue and groove mould 18 is provided adjacent the upper face of the block. Such blocks would preferably be used in walls serving as partitions or curtain walls such as would not be required to support heavy. floors or other loads, and would form a block which would be convenient to handle and tend towards rapid and economical. wall construction. The heightof the blocks 17 would preferably be a multiple of the height of a standard brick and its mortar joints, so that .the laying of one such block would be the equivalent of two or more standard bricks according to the multiple eniiployed. I

i It will be apparent from the foregoing description that the tie blocks 11 may be set in any desired posit-ion between the stretcher blocks 1 or 9, so that close bonding of the latter may beprovided, or that large vertical cavities may be formed for the endoblocks,

sure of soil stacks, heating pipes and the like and that the stretcher courses may be extended into other stretcher courses at wall intersections to bond the corners and also that effective lateral bonding between adjacent courses may be provided intermediate.

the length of some of the stretchers forming said courses without the need of cutting or the use of headers.

' lVhatI claim as my invention is:

1. A wall construction comprising spaced courses or superin'iposed' load sustain ng with the blocks of each course arranged in end to end relation, the base portion of each block being extended inwardly and upwardly to provide a hooked ledge and a plurality of relatively spaced tie blocks inserted" between said courses each tie block being, iorrned with integral extensions adapted to interlock with the hooked ledges of the load sustaining blocks of said courses.

2. A wall construction comprising outer and intermediate courses of loadsustaining blocks, the blocks of each course being arranged in superimposed rows and in end to end relation, the base portion of each block of the outer courses being extended inwardly and upwardly to provide an integral hooked ledge and the base portion of each block of the intermediate course being extended outwardly and upwardly at each side of the block'to provide hook ledges correspondto the hooked ledges of the blocks oi? the outer courses and a plurality of relatively spaced tiebloeks arranged between the outer and intermediate courses of the load sustaining-blocks, each tie block being provided at opposite sides with integral downwardly facing hooked portions adapted to interlock with the hooked edges of the load sustaining blocks.

Dated at Vancouver, B. 0, this 26th day of March, 1927.
