'7 Claims.

This invention relates to bricks. The herein illustrated form of brick construction is particuarly adapted for paving purposes. For this reason, the invention is shown embodied in a brick, which may be made by a machine of the type shown in Letters Patent No. 1,809,601 granted June 9, 1931 to Jacob Nesley Porter. In burning bricks in a kiln provision must be made to adequately support them in spaced relation to prevent distortion and marking and insure uniform heating and burning by the kiln atmosphere and cooling while progressing through the kiln, whereby the bricks may be handled and transported without danger of their corners and ends breaking ofi. At the same time, the total area of the spacing lugs must not exceed a predetermined amount as compared to the area of the lug carrying face of the brick, to permit the supply of sufficient filler or grouting when the bricks are laid for sealing the spaces between the bricks.

One object of the invention is to provide an improved construction of bricks each having on one side projecting lugs the shape, size and arrangement of which secures the above advantageous results when the bricks are stacked in a kiln for burning and when assembled to form a pavement.

Another object of the invention is to provide an improved brick having spacing lugs on one side and ends shaped to provide adequate flow of the grouting and a locking and sealing relation between the bricks when the grouting sets.

A further object of the invention is to provide an improved brick having on one side spacing lugs the lateral walls of which are shaped to facilitate the flow of the grouting or filler used in laying the bricks.

Other objects of the invention will be apparent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawings, wherein Fig. 1 is a plan view of a plurality of bricks constructed according to an embodiment of this invention, showing the bricks in nested form on a kiln truck or when laid as a paving.

In the drawings, I indicates a fragmentary portion of a pavement constructed of bricks 2 embodying my invention. The bricks 2 are of similar shape and size, being preferably provided with rounded corners, and are of the type known as vertical fiber grooved lug brick, as the cut surfaces 2 of the bricks are laid upper-most, to provide a substantially non-skid driving surface, with the lugs projecting from the die formed vertical faces or sides to space the bricks of adjoining courses. Each brick 2 is provided on one side} with pairs of lugs 4 arranged inwardly of and equal distances from the opposite ends 5 and lateral edges of the adjacent side 3 and an in termediate pair of lugs 6 arranged centrally of the side 3 and inwardly of and equal distances from the lateral edges of the side 3. As shown, the lugs have flat top supporting or engaging surfaces 1 in the same plane and the lugs of each pair are so related that when the brick is laid,

as shown in Fig. 1, they are in a vertical plane, 20

one above the other. The top surfaces 1 of the lugs 6 are relatively long longitudinally of the side 3, as compared to the length of the lugs 4 in the same direction, and extend equal distances to either side of a transverse line mid-way or centrally between the ends-of the side 3. In this form of construction, a single pair of lugs serves as the supporting and engaging surfaces for the adjoining ends of two adjacent bricks when the bricks are laid as shown in Fig. 1. In setting the bricks in a kiln, the adjacent upper and lower bricks are reversed with their sides 3 in opposed relation and off-set, as shown in Fig. 2, so that the sides 3 of the upper bricks have bearing on the lugs of the lower bricks and the lugs of the upper bricks have bearing on the sides 3 of the lower bricks, the purpose being to increase the area of the bearing surfaces between the bricks. This nesting arrangement increases the capacity of the kiln. As will be apparent from the drawings, the intermediate portion of each brick and its ends are adequately supported to prevent the material at the ends or corners developing weak cohesion characteristics and readily breaking off during handling and transporting. By making the lugs 6 relatively long and the lugs 4 shorter, longitudinally of the brick, the central lugs 6 may adequately support the adjoining ends of two bricks and the total area of the lugs may be limited to the maximum amount (namely, two and one-half square inches) in proportion to the size of a standardbrick.

The lugs of each pair are so spaced relative to each other and the lateral edges of the adjacent side 3 that when the bricks are assembled side by side in a kiln, corresponding lugs on adjoining bricks are substantially equally spaced. The front and rear side walls 8 of the lugs are inclined downwardly and outwardly, whereas the inner lateral walls 8' of the lugs and by preference the outer lateral walls 9 are of curvalinear shape struck on an arc the outer ends of which are tangential to the plane of the adjacent side 3, these walls forming a relatively large concaved groove the purpose of which is to facilitate the flow of the filler or grouting below and between the lugs to insure anchorage of the bricks against relative displacement. Where each end 5 of each brick is shaped to form inclined faces extending from a transverse medial line inwardly to the opposite edges of the end 5, as shown at I0, I form therein a plurality of parallel concave grooves l0 disposed at right angles to the medial line. The grooves ID are preferably of less depth than the height of the surfaces II] from the base line thereof and therefore terminate at points between the medial line and opposite edges of the adjacent end 5.

In Figs. 7, 8 and 9 I show a modified form of construction in which the die formed end walls 5 are at right angles to the die formed side walls 3 and each end wall is provided centrally with a pair of lugs H which are shaped, arranged and related to each other and the surfaces 2' corresponding to the lugs of the pairs 4, 6. As the lugs l l are arranged centrally of the ends 5, they abut with the corresponding lugs on the adjoining bricks when laid. As will be understood, the grooves between the lugs H in the form of construction shown in Figs. 7, 8 and 9 and groove H) in the form of construction shown in Figs. 3, 4, 5 and 6 provide for the flow of the filler into the spaces between the ends of adjoining bricks.

To those skilled in the art to which my invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves Without departing from the spirit and scope of the invention. My disclosures and the description herein are purely illustrative and not intended to be in any sense limiting.
