CONSTRUCTION OF BRICK PAVEMENTS.

Specification of Letters Patent.

Patented July 30, 1907.

Aspiration flied August 6,1906. serial No. 329,372.

To all whom it may' concern:

Be it known that I, JOSEPH M. PERKINS, a citizen of the United States, and a resident of Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Construction of Brick Pavcments,

of which the following is a full, clear, and exact de scription.

The purpose of the invention is to provide an especially hard filler for the joints between bricks when laid in street pavements, which filler is hard and smooth, is applied in a liquid or semi-liquid state, and will tend to render a pavement less noisy than when laid with the usual fillers, since the tendency of the proposed filler is to deaden sound.

Another purpose of the invention is to provide a filler for brick pavements which will not rot but will be sanitary and will always wear smooth and still will not be slippery under traffic.

Another purpose of the invention is to so construct the bricks for the pavement that when laid the joints will be of equal -width throughout.

The invention consists in tho novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings 'forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure I is a transverse vertical section through a portion of a road bed and the improved pavement laid thereon; Fig. 2 is a plan view of a section of the pavement; Fig. 3 isa top view of one of the improved bricks, Fig. 4 is a side view of one of said bricks, and Fig. 5 is an end view thereof. h i

Ordinarily after a brick pavement has been laid in the street, the joints are filled with either cement or tar or their equivalents, and such fillers being softer than the bricks permit the corners of the bricks to break and crumble, causing the bricks to become practically round, and wear uneven, etc. I aim to provide a filler A, which will be as hard, if not harder than the bricks and which Will wear uniformly with said bricks. To that end I fill the joints between the bricks with melted glass, the glass being ordinarily melted in a portable furnace, but I do not confine myself to any particular means for such purpose. In pouring the melted glass I preferably employ a two-handled ladle, and as the glassis poured the surface of the pavement is brushed with an asbestos rubber provided with a suitable handle so as to distribute any surplus glass that is left upon the tops of the bricksv and thus leave a perfectly smooth surface, such brushing being done quickly while the glass is hot.

Ihe bricks are preferably laid edgewise, that is upon one of their side edges l0, and when so laid at one end Il of each brick and on one wide face l2 teats or projections 13 are formed integral with the brickswhen they are molded. Usually a single end teat centrally located is s uicient for each brick, and on the wide face l2 of a brick four teats are generally formed, two in a row with corresponding teats in vertical alinement, as shown in Figfi; but l do not conne myself to any specific number of teats, or to their location.

The teats I3 are of the same length, and are preferably made tapering, but not necessarily pointed. By means of these teats, when the bricks are laid the joints are all of uniform width; in practice it has been found that the teats need not be more than one-eighth of an inch in length.

In constructing the roadbed, a bed of cement I4 is first laid upon the prepared ground. This is followed by a bed of sand l5 of desired depth, and on said sand bed l5 sheets of building or tar paper 16 are laid, and the bricks are laid upon the paper. The idea of the paper is that by laying the bricks thereon it provides for a smoother wearing surface than if the bricks were laid directly upon the sand bed l5, since the sand would tend to find its way into the spaces or joints between the bricks at the bottom and thus prevent the filler from running to the foundation upon Which the bricks rest.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent,-

1. In the construction of brick pavements, building paper laid upon the upper surface of the bed for the pavement, bricks having spacing projections laid upon the paper and a filler of glass for the joints between the brick.

2. In the construction of brick pavements, buildingr paper laid upon the upper surface of the bed for the pavoment, bricks having spacing projections laid upon the paper, and a filler of glass for the joints between the brick, said filler extending' the full depth of the bricks,

InV testimony whereof I have signed my name to this specification in the presence of two subscribing` witnessesA 'i JOSEPH M. PERKINS.
