NITED STATES JOI-IN RILEY HALDEMAN, OF NORMAL, ILLINOIS.

BRICK PAVEMENT.

SPECIFICATION forming part of Letters Patent No. 481,756, dated August 30, 1892. Application led October 24, 1891. Serial No. 409,687. (No model.)

To all whom it may concern:

Be it known that I, JOHN RILEY HALDE- MAN, a citizen of the United States, residing at Normal, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Brick Pavements; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specication, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in pavements; and it has for its objects to provide an improved brick pavement so constructed that the same will be firm and solid, will not be thrown up during cold weather, andin which the fo undation will be prevented from injury by water or moisture. I make a foundation or a bed of bricks, which are laid latwise diagonally across the street, and upon this I place a layer of cement, upon which the upper layer of bricks are set upon edge. Each brick of the upper layer` thus rests upon two and sometimes three of the lower bricks,and the lower bricks being flat and square have greater resistance than if set upon ordinary sized brick.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon,form a part of this specification, and in which-- Figure 1 is atop plan of aportion of a pavement constructed in accordance with my invention, portions of the upper layer and of the intermediate cement layer being broken away. Fig. 2 is an end View thereof.

Like letters of reference indicate like parts in both of the views.

In carrying out my invention I make the bed-crown sufciently, say, about six inches in the center, laying a tile drain A on each side of the street to carry o the water from the ground and prevent any back-water from getting under the pavement. The road-bed is packed and well rolled, and upon this bed B is placed diagonally across the street the rst or under layer of bricks C, preferably substantially square bricks, about eight inches by eight inches and about two inches thick. These bricks are laid iiat and in close contact with each other, as shown in Fig. l. This layeris then covered and the joints filled with asphalt or anyother suitable substance-such, for instance, as a cement composed of coaltar, shellac, brimstone, and Portland cement, or an analogous plastic cement. This will cement the bricks together Vand prevent water from passing through the lower layer of brick, and thus keep the foundation orbed dry and preventing the pavement from settling. Upon this layer D is sifted dry sand and upon this is laid a second layer of bricks E, set on edge lengthwise across the street, with their ends touching each other and the bricks a slight distance apart. They are set to break joints in the usual way, and then into the joints between the bricks may be poured a little cement to ll up but a little at the bottom, and on this is poured sand to fill up the joints. By laying the under layer of bricks latwise and square diagonally across the street and the top layer lengthwise on edge a greater resistance from the ,bottom is provided, as a top brick always rests upon two or more of the under bricks of the bottom layer, and the bottom bricks being square and laid flatwise will have four times the resistance as if laid of ordinary bricks set on edge, and by keeping the bed dry there can be no chance of the pavement settling or giving away.

What I claim as new is- A pavement composed of a suitable bed, a layer of. square bricks laid flatwise diagonally across the street, a layer of cement lling the joints and covering the said layer, a layer of sand on the said cement, and an upper layer of bricks set on edge lengthwise across the street on `said sand and cement, substantially as specified.

In testimony that I claim the above I have hereunto subscribed myname in the presence of two witnesses.

JOHN RILEY HALDEMAN.

I Witnesses BENJ. LAWRENCE, H. L. FINNEY.
