. VERTICAL FIBER GROOVED-LUG PAVING BRICK Application filed February 7, 1928. Serial No. 252,571.

This invention relates to paving brick and has for its object the construction of a brick adapted to be laid in the pavement with the cut surface uppermost, and having spacing lugs projecting from the die formed surface thereof to space one brick from the next adjoining phalt or other suitable filling material w ll flow downward between the brick when laid in a pavement. These bricks are known as vertical fiber grooved lug paving bricks because the cut surfaces of said brick are laid uppermost, and with the die formed surfaces vertical, adjoining the next adjoining brick I in the course, with the projecting lugs on said die formed surface spacing the bricks apart.

he features of this invention are hereinafter fully set forth and explained and are illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of a column of clay as it emerges from the die of the auger machine.

Figure 2 is a top or plan view of the same.

Figure 3 is a top plan view of a series of vertical fiber grooved lug paving bricks according to my invention.

Figure 4 is an end view of Fig. 3.

Figure 5 is a section on the line 5-5 in Fig. 7 showing one means for forming the grooved lugs on the bricks.

Figure 6 is an end view of a series of the improved bricks with the edge molds thereon, the latter being in sections.

Figure 7 is a section of the same on the line 6--6 in Fig. 5.

Figure 7 is a section of the same on the line 6-6 in Fig. 5.

Figure 8 is an end view of Flg. 6, looking in the direction of the arrow.

In these drawings A indicates a fragment of an auger machine, and A indicates the die secured on said auger machine from which a column of clay is forced in a continuous stream. The orifice in said die is so formed that the upper surface of said column has formed thereon three spaced ribs C, which are raised above the surface C of the column B. The raised ribs C extend from the die A forwardly longitudinally of the column B brick so that liquid cementor hot as and are transversely cut off of the column,

as indicated by the broken lines D, by the cutting wires of the cutting machine, (not shown) so that said raised ribs C, will extend across the upper die formed surface C of each brick, and if the wire cut surface. of the brick are now laid up in a pavement, said raised die formed ribs C will separate said bricks so that fluid filler will fiow into said spaces between said bricks and fill the same.

It has been found, however, that it is ad transversely of said ribs C, leaving a portion of said ribsremaining on each brick, which pro ect from the die formed surface C of the brick as grooved lugs G which lugs C will be uniform in length and will maintain said bricks separate from each other through the pavement.

In Figs. 5, 6, 7 and 8 I show one means for grooving the ribs C, and forming them into lugs in which F indicates a plate adapted to be lowered upon the upper surface of the clay column B, said plate being provided with indentations 7 adapted to receive a portion of each rib C thereinto, and press down the clay of said ribs outside of said indentations, thereby leaving the clay entering said indentations, projecting to form said lugs C WVhile I have hereinbefore shown and described a preferable mechanism for forming the lugs G I am aware that there are many other mechanisms adapted to accomplish the same result, therefore I do not desire to be limited to the mechanism herein shown and described, but what I claim as new and desire to secure by Letters Patent is:

A brick for use in pavements, comprising a substantially rectangular body portion having wear resisting and tractive wire cut upper and lower faces and having relatively smooth and uninterrupted fiat edge and end faces, said body portion having across one only of said edge faces spaced apart broad ribs and the brick adapted to be laid with said ribs abutting the opposite fiat edge face of a like prior laid brick to provide vertical 11m grout filler receiving passages between the ribs and adjacent bricks When laid and hold the adjacent bricks from longitudinal relative movement, and said ribs having spaced depressions extending thereacross and open ing into the vertical passages to admit free horizontal flowing of the filler to anchor adjacent bricks against relative Vertical displacement.

In testimony whereof I aifix my signatnre.

JACOB NESSLY PORTER.
