I INITED STATES PATENT oFFioE.

. JOSEPH SOSS, NEW YORK, N. Y.

Specification of Letters Patent.

Patented Nov. 17, 1908 To all whom it may concern:

Be it known that I, J OBEPH Soss, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in- Interlocking Bricks, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same. I

y This invention relates to building bricks and is more particularly an improvement on so called interlocking bricks, and the object of my improvement is to provide a brick having means of interlocking itself with other bricks of like construction when placed in a wall in successive courses; another object being to provide an interlocking brick which is of such form and construction that in its manufacture it will present no obstacle to an even and thorough calcining in the brick kiln, and will not warp or bend through unequal expansion; another object being to obtain a brick which does not present pointed projections which latter in transportation will suffer by breakage and which would thereby impair its value as an interlocking brick, and I attain these and other objects by means of spherical projections and depressions placed on the two opposite parallel bedding planes of the-brick.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is an isometric perspective view of my improved brick. Fig. 2 is a side view of the same. Fig. 3 a section on the line 3-3 of Fig. 1; Fig. 4 a section on the line 4-4 of Fig. 1; Fig. 5 a section on the line 5+5 of Fig. 1; Fig. 6 is a dia rammatic view illustrating the centers of t e various circular convolutions required in the construction of my brick; and, Fig. 7 illustrates part of a wall built up by means of my interlocking bricks and showing a footing course, one stretcher course and one. header course.

As seen in the drawings the brick a is of the same relative dimensions in length, width and thickness corresponding to ordinary buildin bricks. The top 0 and bottom b or the bedding sides of the bricks are composed of curved surfaces forming pro-, jections -e and depressions d in alternation.

The depressions of one side are 0 posite the projections of the other so that't e brick is at all points of uniform thickness, hence the projections are of substantiallythe same dimensions as the depressions and merge the one into the other without any intervening surface and one brick will fit closely to another when placed thereon.

As in the ordinary bricks in common use my improved brick is of greater length than width and the projections and depressions extend in rows longitudinally of the brick and at right angles thereto, so that when a header course is laid the header bricks will be at substantially right angles to the bricks of a stretcher course and will fit as closely thereon as though the meeting surfaces were the flat surfaces of ordinary bricks. The side and end edges of each brick are strai ht plane surfaces as in ordinary bricks, so t at a wall composed of my improved bricks will presentno eater unevenness than one made of bricks o the usual form.

In Fig. 7 at g is shown a footing course where a brick is employed having one flush face It and one interlocking face i; at k is shown a stretcher course em loying my imroved brick interlocking itself with the ooting course 9 and the superimposed header course Z. As usual in building construction all bricks break joints and my improved brick is especially useful in interlocking all bricks when used solely for a number of superimposed header courses in which case all bricks always 'must break joints with each other. In practice I prefer to make the depressions slightly largerthan the exact theoretical complement of the conical projections, the object being to provide space for a slight additional amount of mortar at this place and also to allow the bricklayer to diverge somewhat from an exact straight alinement in the case of building up walls on a curvature with a large radius.

It will be apparent that by means of this brick a perfect bondage can be obtained in each course and between each successive course, that this brick obviates all defects usually occasioned in interlocking bricks by not becoming subject to breakage of any of the essential parts of the interlocking device and that it is thus easy of construction and magipulation and useful in the building tra Having fully described my invention,

what I claim as new and desire to secure by Letters Patent, is

1. The herein described building brick having the bedding surfaces entirely composed of curved projections and depressions, merging into-each other, said elevations and depressions bein arranged in rows longitudinally of the brick and at right angles thereto, as and forthe purposes specified.

2.. The herein described building brick, having the bedding surfaces entirely composed of alterante curved projections and depressions merging into each other, said depressions and projections being arranged in rows longitudinally of the brick and at right 15 In testimony that I claim the foregoing as 20 my invention I have signed my name in presence of the subscriblng Witnesses this 14th day of May 1906.
