FORMATION 0R PRODUCTION OF BLOCKS Filed Nov. 14, 1931 Patented Aug. 14, 1934 UNITED STATES I 1,969,729 FORMATION on PRODUCTION OF BLOCKS J 050 Damianik, Rio de J aneiro, Brazil Application November-'14, 1931, Serial No. 575,120 In Brazil November 18, 1930 2 Claims.

This invention relates to the formation or production of blocks such as are used for floors, wall facings or the like and they may be in the nature of bricks, tile, mosaic pieces, blocks of wood and ad the like including those structural elements used for pavements.

Usually elements employed in the construction of the foregoing have been formed with relatively straight sides or contacting edges and 110i therefore there is little diversity of contour or outline between the adjacent or contiguous elements.

It is an object of this invention to produce bricks, blocks of wood, pieces for mosaics and the .15 like employed for the purposes heretofore stated to be hereinafter referred to as elements and these are to be employed by assembling them as is customarily done for the purpose of producing wall facings, floors and the like, and it is the purf pose of the inventor to produce elements of this character whose edges are singly or compoundly curved and interlocking so that the finished structure will have curved joints due to the fact that the elements have sides which present ourgaj vilinear faces and contours and wherein only certain parts of the sides and contours in transverse section are rectilinear. By means of the invention it is possible to eliminate the monotony due to straight lines and to obtain a multitudinous variety of patterns in curved lines which result in an esthetic effect of great worth, and this has not heretofore been accomplished.

It is an object furthermore to produce these novel elements that they may be assembled with as great facility as though the edges were rectangular and to produce said elements with edges having recesses and projections which may interengage with other elements having similar recesses and projections.

v With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed. 7

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this specification in which like characters denote corresponding parts in the several views and in which 5 Figures 1, 2, 3, and 4, are plan views of elements of different shapes; Figure 5 is a sectional view on the line 55 of Figure 1;

Figure 6 is a sectional view on the line 66 of Figure 1;

Figure '7 is a sectional view on theline 77 of Figure 1'; g.

Figure 8 is a sectional view on the line 8-8 of Figure 1.

It is obvious that elements of other shapes may be employed and elements can of course be made triangular or rectangular.

The elements may be formed of any appropriate material and of suitable color and the inventor does not wish to be limited with respect 651 to these features.

The elements have curved edges and preferably the curves are compound. In Figure 4 for instance the side of the element is concaved as at A which represents the upper half of the thick- '10 ness of the element whereas the lower. half of this portion of the element has a convexed edge B resulting in a projection C whereas the other half of the same side of the element has a convexed edge D for its upper half and a concaved edge E for the lower half of the edge, and the edge D of course forms a projection which interengages a projection on the juxtaposed element when the elements are assembled. That portion of the edge at F is rectilinear and engages the straight side of a juxtaposed element. The example just described is applicable to the sides of the elements illustrated in the other figures of the drawing, it being understood that the projection on the upper half of the element interengages the projection on the lower half of the contiguous element and that there will be an interlocking or interengaging connection with the adjacent block or such interposed binding material as may be found desirable for use in holding the elements assembled.

For instance in Figure l which is approximately a square element, each edge has a projection on its lower half corresponding to the projection C of Figure 4 and a projection D at its upper half corresponding to that referred to in Figure 4. The edges are duplicated on the four edges of this figure and are intended to interengage similarly shaped edges of elements assembled with them regardless of whether the element is triangular or otherwise shaped.

Figure 3 shows that the projections are duplicated on two of its side edges and is similar to the edges of Figure 1 at its ends and this of course may interengage edges of elements which are triangularly or otherwise shaped.

' Moreover, it will be seen that each of the elements may be considered as divided on a plane G, centrally of its thickness, into two sections; each having convoluted edges with the convolutions of one section staggered in relation to the convolutions of the other section. Then too, it will be observed that each complete convolution consists of a concave portion and a convex por tion and that the convolutions of one section are staggered or offset to the extent of one half a convolution with respect to the convolutions of the other section. Furthermore the convoluted,

edges are formed by axes of cylinders and that square shoulders H are formed between each concave portion and the corresponding convex portion of the other section.

I claim:

1. An element of the class described having upper and lower sections protruding from the body of said element, each of said sections being substantially one half the complete thickness; of said element, the top and bottom plane of each protruding section being on the same plane with the top and bottom surface of said element, each of said protruding sections having its edges convoluted, the convolution of one section being staggered with respect to the convolution of the other section, the extreme edges 01 the said convolutions of the upper and lower sections being perpendicular to the top and bottom plane of said element, the convoluted edges being formed as arcuate cylindrical surfaces.

2. An element of the class described having three or morecsides, a series of convex and concave edges meeting eachlotheron Zeach of said sides, another set of convex and concave edges meeting each other on each of said sides and ara ranged on a lower plane than the first mentioned JoAoV DAMIANIK; 7'
