PAVING-BRICK.

I-ECIFXCATION forming part of Letters Patent No. 487,652, dated December 6, 1892.

Application filed June 23, 1892.

T0 aZZ whom it may concern:

Be it known that I, LESLIE O. TURLEY, a citizen of the United States, residing at Portsmouth, in the county of Scioto and State of Ohio, have invented certain new and useful Improvements in Paving-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 appertains to make and use the same.

My invention relates to improvements in paving-bricks; and the object is to provide a brick of improved construction which when laid in a pavement may not rise above or fall below the level of the remaining bricks composing the pavement, and also to provide means for slightly separating the contiguous faces or sides of the bricks in the pavement,

so that sand, cement, grout, tar, or other filling may readily pass down between the bricks for the purpose of filling all interstices and rendering the pavement firm and solid.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference are used to denote being parallel and equal to each other, and

the surfaces being plain, except upon the sides a a, which latter are formed the one with a groove or concavity 13 running the length of the brick and the other with a corresponding rib or tongue B, so that when the bricks are properly placed in the pavement the convex rib of one brick will fitthe corresponding concavity of the adjacent brick, thereby causing the bricks composing the pavement to mutually support and brace each other, so as to prevent an individual brick from sinking below or rising above the level of the other bricks in the pavement.

To adapt the bricks to be readily laid in forming the pavement without loss of time by reason of a tight fit, the concavities B are Serial No. 437,806. (No model.)

preferably made slightly larger than the convex ribs B. In moldingthe bricks provision is also made for building up a small line of material in relief, so as to form a series of projecting ribs or welts D D on one face thereof, preferably on the same face with the convex rib. These welts may be either straight or curved, but should not be continuous, and are designed to hold the faces of adjoining bricks slightly apart, so as to permit sand, cement, grout, tar, or other suitable filling to readily pass down between the contiguous faces to the under edges of the bricks.

In Fig. 3, instead of a concavity and corresponding convex rib the brick is formed with a rectangular recess E on one face thereof and a corresponding rectangular rib E of slightlyless size than the recess for the same purpose as the concave recess and convex rib of Figs. 1 and 2, this latter construction being preferable in many cases as affording a more rigid connection, which causes the bricks to interlock and be firmly bound together, so as to prevent independent vertical movement of individual bricks. This brick is also formed with welts D D in relief upon its face a for the purpose of permitting the filling, as above described, to pass down between the bricks. It may also be desirable to form the longitudinal rib in sections or provide the same with transverse grooves or channels to permit the passage of the filling below the rib.

In Fig. 4 the welts D are bowed or curved to more readily permit the passage of the filling and prevent lodgment thereof upon the welts. These welts may consist of a small line of material in relief upon one face of the brick only, or upon two or more faces, if desired, and they may be larger or smaller than shown in the drawings. The bricks are formed of clay in the usual manner by means of suitable molds and are subsequently burned in a kiln, forming a hard and solid mass of material which is specially adapted for street-paving purposes. It will be observed that the longitudinal rib and the concavity or groove are placed upon the medium faces or sides of the brick, which are commonly called the Width or depth sides, and not upon either the shortest or the longest measurements, and that the opposite faces IOC of the bricks are parallel and equal and at right angles to every other face, so that when placed in the pavement with break joints, as indicated in Fig. 2, each brick has the immediate lateral support of four other bricks in the pavement and has its greatest thickness disposed perpendicularly to the street, so as to afford the greatest strength where required. The upper and lower longitudinal edges of the bricks may also be rounded from one-eighth to three-eighths of an inch, and the brick may be reversed or turned over, so that if from any cause the upper face of a brick is imperfect the perfect face may be presented to the surface.

Instead of welts of the form shown I may print any desired word or words or number or numbers upon the face of the brick in relief, for the same purpose as the welts and may dispense with the longitudinal concavity or recess and corresponding rib and have all the faces of the brick plain, except the face with the welts thereon, and other forms of bricks than the specific form described may be provided with a line of material in the na ture of a welt in relief, which shall hold the bricks slightly apart for the purpose stated. It may also be desirable in some cases to dispense with the welts, and instead thereof to form small grooves extending either vertically or in a slanting direction from top to bottom on one side of the brick.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A paving-brick having its top, bottom,

vided with a series of welts in relief upon one or more sides thereof extending longitudinally of the brick,snbstantially as described.

3. A brick for street-paving purposes, having'a longitudinal recess extending the length of the brick on one face thereof and a corresponding interlocking rib on the opposite face and a series of welts in relief on one of said faces, substantially as described.

4. A street-pavement comprising a series of reversible rectangular interlocking bricks, each having upon one side thereof a longitudinal recess and a corresponding rib on its opposite side engaging the recess of an adjacent brick, together with a series of welts in relief upon one or more sides of the brick, substantially as described.

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

LESLIE C. TURLEY.
