Specification of Letters Patent.

Patented Sept'l 8. I91 7 Application filed February 10. 1915. Serial No. 7,390.

'1 '11 all whom it may concern llc it known that l. FRANK MtrMuuuwv Suvrnu, a citizen of the United States. residing: at Alhambra. California, have invented a new and useful Building Construction. of which the following is a specifica tion.

This invention pertains to a. building con-- structi'ohintended principally for use in the walls of buildings. The standardized slabs of which the wall is chielly composed are designer] to be cast out. of a suitable ccnientitious substance, said slabs being of such contour that after they have been cast they may be assembled in such a manner as to produce a wall of superior strength, durability and general structural merit. the

.strength and stability of the wall being further secm'ed by the provision of certain hol low piers into which liquid concrete or grout poured to cement together the structure into one compact, stable whole.

An object of this invention is to construct a. hollow wall that will be both light and strong and furnished with improved means to irovide the sides of the wall from bulginw out or the pressure of the liquid grout which is filled into the wall during construction and is allowed to harden in order to cement the assembled parts of the wall together into one solid structure. As an aid to secure this object of the invention, there is provided an improved transverse key slab which is adapted to resist both internal pressure and also external pressure against the sides of the wall, so that the wall will neither be ruptured from the building materials con-- tained within its sides. nor will it be colla sed by external pressure o further strengthen the wall a. metal reinforcement may e incorporated atsuch points as may be desired in both vertical and horizontal directions.

Referring to the accompanying drawings, which illustrate the inveinion, Fi

isoinetrical view of a wall, certain slabs b dug broken away to show more clearly the means for binding the wall together.

Fig. 2 is an isometrical view of one of the key slabs.

Fig. 3 is an isometrical view of a key-slab having a double abutment to rovide for insorting a secondary lon itu inal slab required in !0 formation 0 additional cement 5e piers.

internal face of one of the longitudinal slabs.

Fig. 5 is an isonieti'ical view showing an external face of the slab shown in Fig. 4.

Fig. (1 isan isometricul view of an internal longitudinal slab.

Fig. 7 is a. partial longitudinal section through the concrete contained in the longitudinal pockets of Fig.

Referring! in detail to the drawings. each outer side mrtiou of the wall consists of a series of slabs 9 arranged in longitudinal and in vertical courses. thus forming two sets, designated in Fig. 1 as an inner set A and an outer set ll. These sets of the slabs 9 are arranged parallel to each other. a slab J of one set being placed opposite to a corresponding slab 9 of the other set. thus forming' pairs of slabs the members of which pairs are held together by the

transverse key slabs

11 and 11".

Each member of said pairs of slabs 9 is provided with end extensions 12, the extensiou 12 at one end being preferably at the upper edge and the extension 12 at the other end preferably being at the lower edge. These end extensions 12 of adjacent slabs 9 overlap each other in an edgewise manner, the end of each slab 9 being slightly spaced away from the end of the next slab 5) of the same horizontal course, thus leaving two vertical spaces or slots between the ends of adjacent slabs of the same horizontal course. These spaces are spaced longitudinally apart with respect. to the wall. one of said spaces being at the upper edge of the course and the other of said spaces or slots being at the lower edge of the course. It will be understood, however, that these spaces are never left open, but as fast as the wall is assembled they are filled with the ends of: the key slabs 11 next described.

The transversely extending kdy lslabs 1] are arranged in pairs, the members of said pairs each having end extensions 14 prefcr t bly diagonally opposite to each othdr, which project. into and fill the vertical s amss already referred to between the end of the slabs 9. Each extension 14 of the lay slabs has at its inner edge an overhangin shoulder or interlocking lug 15 which eng ges the base of the looking ledge 16 with Whi h each of the slabs 9 is provided. Said led e .16 is beveled or inclined from side to side to cor respond with the inclination of the face of the interlocking lug 15 of the key lab 11.

Said key slab 11 is provided with an'abutlnent 17, the length of the extension 14 preferably being the same as the thickness of the slab 9, so that when the key slabs are fitted in place the abutincnts l7 fit against the inner sides of the slabs l) and the ends of extensions 14 are flush with the surface of the wall.

By this construction there is provided between the members of the pairs of key slabs 11, space for filling in the cement to form the cement piers 18, through which may' also extend the vertical reinforcements 19. a When it is desired to provide pockets 20 for concrete filling longitudinal y of the wall, key slabs 11 are provided leavin the extensions 14 and shoulders 15 Wit an additional right angled recess 2L. Saidrecess 21 cooperates with an inner set of longitudinally placed slabs '9 which have end projections 22. Said projections 22 seat at the bases of the said recesses 21, of the key slabs 11 Said pockets 20 are filled with cementitious substance, as illustrated in Figs.- 1 and 7. The cement is these pockets is continuous in a zigzag manner hmgitudinally of the wall, and is also continuous vertically. The recesses 21 extend toward the centers of slabs 11 far enough to provide that when the end portions of the longitudinally placed slabs 9 are abutted against the inner sides of said recesses 21, there is left between each slab 9 and the adjacent slab 9, sulficient space to form a space or pocket 20 of the desired width.

Owin to the cdgr-iwise overlapping of the end of slabs 9, a considerable portion of the inner (face of each of said overlappin slabs is brought into contact with the a hesive material constituting the adjacent pier, thus forming a bond or union between adjacent slabs of the same longitudinal course, the cement bond being made more effective by the use of the depressions 2-5, which are arranged diagonallykoppesite to each other, thus bringing said depressions in line with the transversely extending portions of the cement filling. i

In case both the long edges of slabs 9 are made beveled, as shown in the illustrated embodiment of the. invention, there will be left V-joints 26 along the faces of the wall which act as a key for plaster or to receive the mortar for the finished joint.

In some cases it may be preferable to use metal instead of precast concrete in the formation of the

key slabs

11 and 11", but changes of this character, it will be seen, fall within the scope of the appended claims.

In order to cement the side slabs 9 more securely in place, each of said slabs is proi vided with an irregularit on its internal face, this irregularity, in t e illustrated em-- bodnnent of the invention consisting of a depression'izfi into which the cement pro 5 jects in order to bind the slab more securely in place.

The slabs 9 are preferably provided with beveled upper and lower edges thereby pro vidi-ng V-shaped joints 26 along the faces of the wall which may be filled with mortar in order to seal the joints.

I claim:

1. In a wall, two sets of slabs, each of said sets comprising an inner and an outer,

course of longitudinally extending slabs arranged to form the side portions of the wall and to leave aspace extending longitudinally along each side of the wall between the inner and outer slabs of said sets of 39 slabs, the outer course of slabs at each side of the wall having end extensions which overlap each other in an edgewise' manner, there being a vertically extending space at the end of each of said overlapping exten- 35 sions to receive a key slab, key slabs extending across the wall and fitting into said spaces at each side thereof, said extensions being of sufficient length to separate said key slabs longitudinally of the wall to form cement-receiving pockets or spaces, and a filling, of adhesive cement occupying said pockets or spaces.

2. In a wall, slabs extending len 'thwise of the wall at each of its outer si es, the

slabs at each side of the wall being arranged in horizontal courses in which contiguous slabs are provided with end extensions which overlap in an edgewise manner and are slightly spaced apart from each other lengthwise of the wall, key slabs the ends of which occupy the spaces thus provided at each side of. the wall, said key slabs lee-- .ing arranged inpairs the members of which are, spaced apart lengthwise of the wall by of adhesive cement occupying the etween the members of said pairs of key slabs.

In testimony whereof I have hereunto signed my name in the scribing witnesses at Los Angeles, in tha county of Los Angeles and State "of Cali fornia, this fifth day of February 1915.
