BUILDING BLOCK.

" Specification of Letters Patent. P t nt J l 2 Application filed j'anuarylO, 1921.- Serial No. 436,244.

To all whom may concern:

Be it known that I, HARV Y L. EMERY, a citizen of the United States, and. a resident of Worthington, county of Greemand State of Indiana, have invented. a certain new and useful Building Block; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to building blocks which are adapted to be layed or assembled together to form a wall. The chief object of this invention is to provide an improved building block which will interlock with others of the same kind to form a rigid wall.

Another object of the invention is to construct a block such that the same will be light in weight' and also when assembled will form a ventilated wall construction.

The chief feature of'theinvention consists in providing a hollow block with suitable openings communicating therewith and with suitable projections upon the surface thereof.

The full nature of this invention will be understood from. the accompanying drawings and the following description and claims. i

In the drawings Fig. 1 is a perspective View of a corner of a wall, the, same having an opening therein and illustrates the blocks in assembled relation. Fig.2 is a top plan viewof the usual wall block. Fig. 3 is an end view thereof. Fig. 4 is a central cross sectional view taken onthe .line 4:4:

of Fig. 2. Fig. 5 is'a top plan view of the corner block. Fig. 6 is a central cross sec tional view taken on the line 6-6 of Fig.

In the drawings Fig. 1 illustrates seven different modificationsof the block embodying; the invention. 10 indlcates the wall generally, 11 indicates the usual or ordinary wall block, 12 indicates the usual corner block. 13 indicates the usual end block. 1 f indi-' cates the usual base block, 15 the usual corner and base block. 16 indicates the usual half block and 17 indicates thczusual half base block. from Fig. 1 that the base blocks 14:, 15 and 17 differ but little from the blocks 11, 13 and 16, and it will'be further noted that the block 16 differs but little from the usual wall block 11. Therefore, there is illustrated in It will be readily understood Figs. 2 to 6 inclusive the usual wall block and the corner block so that a complete understanding of the invention may be had.

One of the chief features of theinvention s that opposite sides of each block are substant ally identical, so that the various end blocks or half blocks may be closed at one end instead of being open at both ends.

. In Figs. 2. 3 and 4 is illustrated the usual wall block which is provided with a hollow core or center 20 which 'in the present in stance'is substantially cylindrical in form, it being found that the block can be moulded very easily in this form. Howeventhe articular form of the central opening or 01- low center 20 is not restricted thereto. Two opposite faces 21ofthe block are preferably plane and may beflat, roughened, corrugated or otherwise finished in any suitabl e manner. Each of the ends 22 is provided with an opening 23 which communicates with the central hollow portion '20, as

shown.

The other two opposite faces are substantially similar and preferably identical and,

therefore, a description of one will sufiice for an understanding of the other. The block in its present form is provided with four projecting portions or lugs 2 one at each corner of the block and suitably separated by a space 25. The two spaces may be of anysuitable width, but preferably are substantially the same width as the width of each of the projections 24. The corner projections 2d are also separated by an elongated space 9.6 which space, of course, is of the same width as the projections 24 and preferably is twice as long as the length of said projections. The central portion of the surface hereinbefore described is provided with acentral projection of substantially twice the length of the corner projection and-substantially the width of said projections, but not necessarily so. The width of the central projection 27 is substantially that of the spaces 25. The spaces 25 and projection 27 are provided to prevent movement of the blocks in planes trans-- versely ofthe sides 21. Also, each space 26 is adapted to accommodate two adjacent corners 24 of two adjacentblocks 11 while each elongated central projection 27 is adapted to be seatablein two adjacent spaces 25 of the two adjacent blocks. Thus, the

projections 24 and spaces 26 prevent movement of the blocks in planes parallel to the sides 21, while the projections 27 and spaces 25 prevent transverse movement as hereinbefore described. 7

In order to provide that the block will form a ventilated wall or hollow wall con struction, theinsulating and other advantages of which are well known in the art, each ofthe spaces 25 is provided with a suitable opening or slot 28 which communicates tion said blocks are not provided with the" I central opening 29, but are provided with 7 an end opening 28. However, even the opening 28 may be omitted if desired, since the block communicates-with the remaining- "blocks through one of the openings23 there- 0. "corners of the block-are provided with the block.

with the central hollow portion '20. In order that therema'y be complete communication a median aperture or opening 29 is provided in the central projection 27 and said opening or aperture communicates with the hollow portion or chamber 20 of the slot 29 on the same block. Other spacing and openings may be substituted for those herein described, if desired, without departing from the broader features of the invention. It will beunderstood that the base block 14 is substantially similar to the block here- 'inbefo re described except that one of the corrugated or formed faces may be made flat I sothat said block will rest securely upon a level surface, such as the ground, sub foundation or foundation.

The end block 13 is also substantially identical with the ordinary wall block 11 except that oneend 22 thereof is preferably closed, as indicated'by the numeral 30 in Fig. 6. In this modification, however, the opening 28 adjacent the closed endg30 may be omitted if desired, and preferably is omitted, althoughthe same is not necessary. The half blocks 16 and 17 are provided with one closed end 30 and in the present inven- It will be understood that the half block isconstructed substantially similar to theusual wall block, except that but half of the block is used. Therefore, the two corner projections 24 and the usual central projection is positioned medianly of the other edge and is but half the length of the usual central projection.

lVhile said openings 28 and 29 may In Figs. and 6 there is illustrated in detail a corner block 12 which differs somewhat from the blocks liereinbefore described."

When the building blocks are approximately twice as long as they are wide, the corner block consists of substantially two square half blocks positioned at right angles to each other. Thus, one half of the corner block is provided with the usual corner projections 24, a central projection 27, separated by the median space 25 and the central space 26. The central projection 27 and central space 26 are of but one half the usual length. The other half of the block consists of a similar number of projections and spaces similarly positionerhbut 318013031- tioned at right angles to the projections and spaces hereinbefore described. ltwill also be noted that the end of this block is closed as at 30. If desired, the end block may be provided with the openings 28.

While the invention has been described in great detail, various modifications thereof will readily suggest themselves to those skilled in the art to which this invention applies, but such modifications are considered, to be within the broad purview of this invention. a
