BRICK.

SPECIFICATION forming part of Letters Patent No. 591,788, dated October 12, 1897.

Application filed June 7, 1897. Serial No. 639,639- (No model.)

To all whom it may concern:

Be it known that I, HENRY PENNIE, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bricks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap-- pertains to make and use the same.

My invention relates to a brick of novel construction, the object being to provide bricks for building purposes having depressions or indentations arranged as hereinafter described and claimed, into which the mortar or cement will enter to more firmly secure the layers of bricks together.

In the accompanying drawings, Figure 1 is a perspective view of a portion of a corner structure built up with bricks embodying my invention. Fig. 2 is a vertical section on the line a: 00 of Fig. 1. Figs. 3 and 4 are respectively a top or plan view and a side elevation of one of the bricks; and Fig. 5- is a plan view of two bricks, one overlappingthe other.

Each of the bricks l is formed on both its top and bottom faces with conical depressions or indentations 2, the depressions or indentations on one brick being adapted to register with those of the next adjacent brick in a wall or structure, whereby the registering openings serve as pockets to receive the mortar or cement laid between the bricks, as clearly shown in Fig. 2, thus forming when the mortar dries and hardens a series of dowels 3,

which materially increase the strength of the structure.

The conical depressions are arranged in pairs, as best shown in Figs. 3 and 5, those on the upper face 4 of the brick being so placed that a line drawn from the depression 5 to the next one, 6, would be at an angle of approximately forty-five degrees to the end 7 of the brick, and the other pair of openings or. depressions 7 and 8 on the upper face 4 of the .of the brick is the reverse of that shown on the upper face, (see dotted lines, Figs. 3 and 5,) so that, for instance, a line drawn from 5 to 6 would cross at its center a line drawn from the holes 9 and 10. This relative arrangement of the pairs of holes or depressions results in bracing the joint between adjacent bricks in the directions indicated by the arrows in Fig. 3. vantage in the building of corners, as shown in Fig. 1, since the'cement dowels are in the lines of strain at opposing angles, and hence tend to securely brace the structure through the corner after the manner of a corner-iron or tie-rod.

While myinvention is, of course, not restricted to any specific means for forming the conical holes or depressions in the bricks, I preferably accomplish this by providing the brick -m0lds with conical spuds or projections, which readily enter the clay and owing to their conical form are readily withdrawn therefrom, leaving the desired openings or indentations in the opposite faces of the bricks.

Having thus described my invention, what I claim isl. A brick provided with depressions or indentations on its opposite faces, the indentations in one face of the brick being arranged at an angle to those in the opposite face of the'brick.

2. A brick having a plurality of depressions or indentations in its upper face, said depres- .sions or indentations being arranged in pairs at an angle to similar pairs of depressions in the under face of the brick.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY PENNIE. Witnesses:
