Application iilctl February 27i 1902. Serial No. 95,905. (No model.) l l Be it known that we, Felini; A. Snai-nem" and GEGRGE il.Stnvllnisitizensot theUnited States, residing,r ai; Union City, in the county 5 et Bra-noli, lfltate et Michigan, have invented certain new' and useful linprovenients in Building-Blocks;and wc do hereby declaro the following to lio a nll, clear, andexact de soription ci the invention, such as will ena-ole to others skilled in the art to which itappertans to make and use the saine.

This invention relates to building .blocks or ln'iclts and nai. elderly to that elass formed of plastic mater ntl and su bseqnently naked; and

t5 it han for its object to provide an article olf `this nature 'n' ith will ne light and durable and which will insure against displz'tcetnent when incorporated in a building.

Other object-s and advantages of the innen eo tion 'will lie understood from the 'following de soription.

In the drawings forming a portion ol' this speeitlcation, and in which like numerals of reference indicate sin] ilarfparts in the several a5 views, Figure l a perspeotive view nliowing that open end of tlio hlockwhioh is provided with lugs.l i?. is an elevation showing the opgosite end of the block. Fig'. 3 is a section on line il Il ol Fig. l and inclut'ling,` the abnigo ting;l portions ot two blocks. Fig. t isa section on line ai lof Fig. l and showing the engaging corrugated portions of two blocks.

Referring; now to the drawings,thebnildingbloclr comprises the flat fao-es or portions 5 35 and G and the connoeting sides and 8, on

which latter are formed the longitudinal ribs .3 and 10, which are Conversely corrugated, so

that. two blocks may he disposed with the co1'- rugations-oi' a rile i) meshing,r with the coi-rn- /io gations of the rib 10 ol an adjacent bloeit, the

sides or walls 7 and S of said blocks at the sides of the rios lying in spaced relation to receivc a iilling ll of mortar. ln. this manner the blocks are held against displacement in ...1.5 one direction. The bloeit is hollow, as shown,

and upon one end ci' eaeh Wall .7 and S is formed a .linger 12, 'which is set inwardly, as

showznso that when 'the open end oi one block is disposed against the open end of another block these fi tigers will engage Within the open 5o end ot. the second block, and by lying in close contact with the inner faces of the Walls 7 and 8 and with their side edges against the inner faces ot' the walls 5 and will hold the blocks.v against lateraldisplacement. '.lo provide-an '55 interspace between two blocks to receive m01'- tar,the walls 5 and G of the block have at the saine end ofthe block With-the fingers 12 ings 13 adjacent to the inner faces of the walls, and which lugs rest upon the opposite 6o end of 'the next block, as shown in Fig. 3. In the end faces of the walls 5 and 6 and lout-- wardly of the lugs are formed longitudinal grooves or channels le angil, respectively.

ln the ends of the walls 5, G, Land S opposite 65 to the lingers 12, which is the top of the block, are formed channels 16, V17, 18, and 19, respectively, and which channels intersect. The. channels in the adjacent ends of two blocks receive a part of` the mortar that is placed be- 7o tween the blocks, and the blocks'are thus keyed together and the mortar is prevented from falling ont.

It will be seen that with the useof blocks formed in accordance with the presentinven 7 5 tion a-wall may be built that will withstand strains in any direction without displacing the blocks, while the Wall' will be cellular in structure, and will hence be lighter than when iliade solid. A-

In practice modifications of the spectic construction shown may be made and any suitable materials and proportions may be used without departing from the spirit of the inj vention. S5'
