To all whom t may concern:

Be it known that I, NICHOLAS J. Mnsoro, a citizen of the United States, and a resident of ll York, county of Bronx, and State of New York, have made certain new and useful improvements in Concrete-Ealab Buildings, oi which the following is a specification.

This invention relates to a concrete construction, applicable to concrete buildings of various kinds and particularly garages. An object of the invention is to construct the slabs or blocks comprising the building by means of forms and molds and in such manner they may readily be assembled and locked together to form the building construction for which they are designed. A "further object of the invention is to so form the slabs to permit their ready disassociation from their complementary members in the building, thus providing a portable or take-down structure.

lhc invention will be understood by reference to the accompanying drawings, in which- Fig. 1 represents a fragmentary plan view or" part of a building constructed in accordance with my invention.

Fig. 2 is a similar fragmentary side elevation of the building.

Fig. 3 is a fragmentary sectional end elevation on the lines 83, Fig. 1.

i is a perspective view of a corner slab constructed in accordance with the invention and Fig. 5 is a fragmentary plan view illusti fng a modification or the locking means the slabs.

In Fig. 1 the side slabs 5 of the building are indicated in dotted lines 1. It will be seen that these side slabs are formed with straight side edges 1", although each may be formed at one side edge with a groove and the opposite side edge with a tenon so that contacting slabs may mutually interlock, if desired. 2 represents the top slabs which meet at 2", each top slab. preferably overlapping the top of two side slabs. 3 represents a bolt for securely interlocking a top slab and its appropriate side slab, and in the embodiment shown two of these bolts are provided for at each end of the top slab, the two bolts engaging two separate side slabs as represented in Fig. 1. Bolts 3 pass vertically through the top slabs and thence downwardly through vertical apertures 4 formed on the sideslabs 5 (see Fig.8) an thence in the pockets or recesses 6 tormed on the side slabs, these pockets being of sufficient area to permit the insertionoi a not 7 onto bolt 3, the nut being turned so that the two slab members are firmly drawn together.

The top slabs are firmly held together by means of bolts similar to those shown in Fig. 3. it is usually unnecessary to employ more than a single bolt for each slab, although any desired number may be employed. In Fig. 1 of the drawing I have shown each top slab having molded therein a bolt 8 having a projecting end which passes through aperture 9 formed in the complementary slab, the latter slab having a pocket 10 in which the end of the bolt projects so that it may be engaged by means of a nut 11.

The side members are held firmly together by means of boltsand nuts such as those employed for securing the top slabs, it generally being suflicient to provide each slab with two projecting bolts 8 (Fig. 2), and two pockets 10 having registering apertures 12, so that the projecting bolts 8 of one slab will fit within the apertures 12 and pockets 10? or" the adjoining slab and be held therein by means of the nuts 13. If desired, however, the bolts 8 need not be molded into the slabs, and the modified form of locking means shown in Fig. 5 may be substituted. As shown in Fig. 5 each slab, in the modification, is formed on the opposite sides with two pockets 11 and a bolt 14: is used which is threaded at each end. Prior to assembly of the blocks, bolt 14: may be placed in the appropriate aperture and pocket 11 of one slab and threaded into a nut 13*, whereupon the adjoining slab may be placed in position and locked by means of a nut on the opposite end of bolt 14;.

In Fig. 4:, I have illustrated a corner slab which may be provided with a suitable number ofpockets to receive bolts for securing top and side slabs. In forming a doorway a top beam such as that indicated in dotted lines at 15 may be laid .upon member A or B and secured in position by means of a bolt indicated at 16 and extending into a suitable pocket formed in the said corner slab.

It will be understood that various modifications may be made in the embodiments illustrated in the drawing without departing from the spirit of my invention, what I claim and desire to secure by Letters Patent being as follows 1. In a concrete slab building, a series of concrete slabs placed edge to edge, forming a wall construction, a bolt held by each slab and projecting from its side edge and also projecting into a side edge aperture formed in a contiguous slab, said contiguous slab having formed therein a side wall pocket into which said bolt projects,and a nut on said bolt and engaging a wall of said pocket.

2. In a concrete slab building construction, a slab provided with a plurality of bolts projecting from one side edge and a plurality of apertures formed in the oppo- 15 site side edge and in line with said bolts, the slab having pockets formed in its side Wall each pocket communicating with one of the said apertures, for the purpose described.

Signed at New York, in the county of 20 New York andv State of New York, this 1st day of March A. D. 1923.
