To all wkomrlt may mm.- v i Be it'known that I. EMIL C. SIX'rA a citizen of the United States, residing at.

Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful lmprovements in Building Blocks, ofwhich the following is aspecification. p

M invention relates to improvements in building blocks, andmore particularly to. that class or type. which are adapted to interlock with each other-when theblocks are laid or set up in the completed structure;

The primary object is to provide agenf provision of a series of blocks of anovel.

construction which may be joined together in various ways to produce different kinds of building structures and which may be arranged in different ways in the same structure to vary the ornamental appearance thereof.

A still further object is the provision of novel interlocking means requiring the blocks to be laid or set up in a novel manner, so that when the structure is completed the samemay be lifted up and moved from one position to the other without breaking up or disarranging the blocks or units and when it is desired to teardown the same requiring that the blocks be removed in substantially reverse order to the building up of the same in the original structure.

With the above mentioned' and otherends in view, the invention consists inthe novel construction, arrangement, and combination of parts, illustrated in", some of its. embodiments in the accompanying. drawings,-and

particularly pointed out in. the appended claims.

Referring to the p 01" this speclficatlon, Figure 1 1s a Irontelevation of a building builtup witlrmy improved interlocking blocks .or units.

Upon reference to the drawings, it wlllbe seen that the building structure is made up a of 'a plurality of blocks or units suitably arranged and interlocking, as hereinafter described. I The various building blocks or units may be of any suitable and convenient material andxlikewise of any suitable and convenient .form. For example, certain blocks may take thespecific form or suitably ornamented base blocks 1, to form the initially laid base or foundation of the structure and suitable cornice forming blocks 2,

the windows being formed by means of side bar formingblocksB', adapted to interlock with suitable projections or tenons 4 and 4 of the transverse frame forming blocks l. In the present instance, the base window block l is provided with subjacent hook shaped projections 4 (corresponding to the hooked projections on the regular blocks or unitshereinafter described) adapted to interlock with the flanged recesses of the subjacent regular blocks or units 5.

It will be seen that. each block {or unit 1, 2;: or 5 is "provided-with oppositelyarrange'd recesses and projections adapted to receive and interlock with the corresponding'projec y tions and recesses of superposed and subjacent blocks, respectively, when set .llpl' ifil corner flanges or projectionse As a means of interlocking a"superposed blockor unit with theundercut projections 5 of the sub j acent units, eachu'nit'or block is provided with depending"projections 5, said proje c tions 5, inthe present instance, being spaced apart to fornran intervening tenon receiv= ing recess'5 'fa-nd being provided with horizontally extending orojections 5 adapted to enter beneaththe projections'5 of aipair' ot' subjacent blocks when-laid, as shown most clearly in Fig. 4 of the drawings. It will'thus be noted that the parts 5" and 5 of the --proj ections form substantially hook shaped projections facing towards the outer sides or the wall and thatfindaying up the blocks each block to be placed in position will be initially placedsliglrtly 'to the rear of the subjacent blocks and moved forwardly with the front edge thereof flush' with the two subjacent blocks, therebycarrying the ton ues orfree ends of the hooks'5 beneath thecorner projections 5 of thesubjacent blocks. Upon reference to Figs. 2, 7 and' 8 of the drawingsitwill'be seenthat the cornice-block 2 lacks the under cut recesses 5, 5" and projections5 tormed'in the top portions ot'the regular blocksbut is providecl with the corresponding hook shaped portions 2 and 2 with the tenon receiving recess 2 Upon reference to Fig. 5 it willbe seen, on the other hand, thatthe base 'block 1, lacks the depending ,hook shaped projec tions but'isjprovided'with a main recess and second'recess 1 forming corner projections 1,"and corresponding to the partso 5 and 5 ofthe'regu'lar blocks." Similar remarks apply to the transversewindow or door frame blocks 4, it .being notedthat the upper block 4 is provided with a mainiunder cut'rece ss 4 and a second or smaller recess i forming the undercut corner projections 4L, and in this connectionit will also be noted thatthe blocks 4L are provided with tenons, adapted toenter into recesses or mortise openings 3, in the side bar forming blocks 3. The'side'bar forming. blocks 3 may be provided withrecessesfi on their'inner sides to receive thesash frames and by the use of the drawings, such blocks 3 may be ex tended to form the side bars of the door framesar Somewhat similarly Lshaped bar forming blocks 7 provided "with grooves 7*,

may be used in forming partition wall supl porting bars and-horizontal floor supporting bars or joists, as shown in Fig. 7 of the drawings In such instance it will be also seen that iiller blocks 6, such as shown in Figs:'10 and 11-, areutilized in forming the joints or connections between the vertical horizontally extending wall supporting bars orfbeams and that similarly shaped filler, blocks may be us'ed in making desired lengthsorextensionsof such beams, the

'filleribl'ock's" 6 being provided with, tenons 6*, adapted to enter into mortise openings,

in the adjacent blocks to be supported.

Referring to Fig. 8 of the drawings, it

will be seen that root or rafter forming blocks 8, are provided, said blocks 8 being provided'with roof. or board receivingrecesses 8,1nthe1r sides and being'provlded j at their endswith mortise openings 8 to re ceive tenons 9 and 10, of key forming blocks provided with tenons 10", adapted 'to enter Having thus described some of the embodiments of my invention, without having I attempted to setforth all the forms in which it may be made,"or all the modes of its use, what I claim and desire [to secure by Letters Patent, is,-

A. building block having main and supplemental recesses on its top extending from the rear thereof and forming corner projections, said block being provided on its lower side with spacedhook shaped projections extending towards the face of the block to enter into the recesses of a subjacent block from the rear thereof and to interlock with said corner projections when in place.

15. A buildingblock having undercut recesses and projections on its top and under sides to receive and interlock with corresponding undercut projections and recesses of superposed and subjacent blocks, respectively, said undercut recesses and pro ections being spaced apart to form mortise recesses between theblocks on the inner sides thereof for tenons of adjacent blocks.

In testimony whereof I have affixed my signature.
