HORIZONTALLY-OORED BUILDIN G BLOCK.

Applieationfiled April 25, 1928. Serial No. 272,851.

The invention relates in general to a hollow block building wall construction and specifically relates to ;-a form of hollow building block used in forming such a wall 5 construction. The present disclosure constitutes a development of the invention disclosed in my ending application Serial No. 231,762 filed. ovember 7, 1927.-

' In the drawings accompanying the above identified application there was disclosed. a

form of hollow tile buildin block in which the cores extended vertically so that when assembled into the wall construction, vertically extending tiers, conduits, pipes and mortar keys could be received in the vertical aligned openings. In the present disclosure a similar form of block is disclosed distinguishin in one respect from the individual bloc in the co-pending application by a disposition .of the cores extending horizontally. and lengthwise arallel to the greatest dimension of the bloc The primary object of the invention is to provide a hollow building block of the horizonta-lly cored type in which vertical strains originating in either of the outer load carrying walls may be transmitted through the intermediate, connecting. cellular construction and directed therethrough downwardly into the opposite wall, whereby one wall will tend to assume the load imposed on the other wall without tendency to rupture the connecting webs forming the intervening cellular construction.

Another object of the invention is to provide a hollow blockstructure designed to provide troughs for receivin conduits and similar members and the cel ular structure of which is d'is'p sed to distribute the weight of such- 0 duits and other inserted bodies to the outer massive load supporting walls without'adding material to the cellu- .-.-'lar structure for this purpose.

" Another object of the invention is to provide a simple form of block of the type out- "lined inwhich the outer load sustaining walls are cored-to facilitatebreaking away 1- f por'tions of these walls to permit the staggei'lng of. connecting joints in the wall structure,-- f to permit insertions of key blocks,

mortar strips and the like while preserving the reinforcing eflect inherent in the cellular structure connecting the load sustaining walls.

Various other objects and. advantages of theinvention will be in part obvious from an inspection of the accompanying'drawings and in part will be more fully set forth in the following particular description of one form of mechanism embodying my invention, and the invention also consists in certain new and novel features of construction. and combination of parts hereinafter set forth and claimed.

In the accompanying drawings: I

Figure 1 is a perspective view of a portion of the wall formed of blocks constituting a preferred embodiment of the invention; and

Figures 2 and 3 are similar views of walls formed from blocks constructed by mutilating the standardized blocks shown in Figure 1, and by mutilating the right wall of a three wall form of building block.

In the drawings and referring particularly to Figure 1, there is disclosed a rectangular block 10 of greatest length considered horizontally and with its four outlining vertical walls substantially flat to form fiat ends and sides. Each block'comprises a pair of arallel, Vertically extending, relatively thick load carrying walls 11 and 12, each provided with horizontally extending cylindrical cores 13. A cellular structure 14 extends between and integrally connects walls 11 and 12. This cellular construction is substantially H-shaped in vertical, transverse sectional elevation as' shown in Figure 1 and comprises two vertically spaced and horizontally disposed curved webs 15 and 16, the end portion 17 of which merge into the adjr' ent wall at an acute angle and coact therewith to provide arelatively thick portion 18 to the wall opposite the jointures of the ends of the 5 webs. These webs are relatively thin and are substantially semi-circular in elevation with their concaved faces forming the central portion of the top and bottom of the block. The .convexsides of the webs 16 and 17 faceeach other and are connected at their crown portions by means of a relatively thin, vertically disposed web 19 equi-distantly s aced between the walls 11 and 12 and c acting therewith to form horizontally extending cores 19".

1 In assembling the blocks to form the wall as shown in Fig. 1, the load carrying walls are disposed in vertical alignment and as .these walls are of the same width the blocks may be reversed, that is, wall 11 of one block may be disposed on wall 12 of the block next below. The upper web 17 of the lowermost block coacts with the lowermost web 16' of the upper block to form a horizontally extending core 20 between the blocks, and centered between opposite faces fof .the wall and substantially circular in vertical transverse section as shown in Figs. 1 and 3. a

' In the showing in Fig. 1, a conduit 21 is positioned in this core 20 and disposed'in the trough formed by the upper web 17 of the lower block. By this arrangement the weight of the conduit 21 is distributed to the side walls 11 and 12 ofthe lower block through the webs of the lower block. The weight will act on thelupper web placing the same under tension and will act through the middle web 19 therebeneath to transmit strains to the lower web placing the lower web under compression. In this way it is appreciated that .the weight of the conduit is distributed vsubstantially uniformly to both of the load sustaining walls and the curved disposition of the webs will tend to direct the strains along the planes of greatest dimension of the'webs and cause tlre same to. merge into the hea 1 outer walls downwardly or in the dirlf; on of greatest mass of material in these outer walls.

Referring to the end cores 22 of the block it will be noted that they are in each instance in the thickened portion 18 of the wall opposlte the ends of the curved webs. By this construction it is possible to break out a portion of the outer face and at one edge of the block as noted at the lower left hand side of Fig. 2 and any such breaking away will not affect the reinforcement provided at this point by the jointure of the ends of the curved webs as they merge into the load sustaining wall. Into this cut away portion may be inserted a mortar strip 23 or other insert usually positioned in walls of this character. It is also possible to cut through elevation so as to horizontally stagger the joints 25 and 26 as shown in Fig. 2.

In the showing in Fig. 3, both of the superposed walls on one side of the wall con- ,struction have been cut-away as above suggested to provide a key block receiving space 27 on one side of the wall in which is fitted a key block 28. From this construction itwill be noted that strains in the lower curved web 29 of the upper block 30 is transmitted to the lower block through the key 28 and is also transmitted through the cellular construction of the lower-block 31 so as to distribute strains originating either in the superposed block 30, in the key block 28 or in the facing wall 32 to the lowermost, block 30.,

In the showings in Figs. 1 and 2 there has been illustrated the simplest form of block which will function as described and which comprises only two load sustaining walls 11 and 12. It is obviously within the scope of the disclosure to increase the number of load sustaining walls and in the showing of the bottom block of Fig. 3, a three walled type of block is illustrated functioning as an extra wide foundation block. The three walled block of Fig. 3 can be substituted for the two walled types of blocks shown in Figs. 1 and 2.

By means of the structure herein disclosed it is possible to utilize all of the advantages relative to economy in construction and, in cost of material featured in the above identified application and atthe same time provide a block of the horizontally cored type particularly designed to receive and transmit to the massive load sustaining walls those strains which are usually imposed on a wall from the contained conduits and the like and from the floorings, facing strips and the like. It is also possible to provide a standardized form of block which can be readily modified to meet specific requirements relating to the accommodation of parts designed to cooperate with wall structures and to receive conduits and other weighted members without necessity of specifically providing structural parts to compensate for the weight added by such members. v I claim:
