VA|=IT| FlolAL-STONE PAVEMENT.'

SPECPIC'ATON forming part of Letters Patent No. 378,000, dated Pebruary`l4, 1888.

' Application led August 12, 1887. Serial No. 246,798. (No model.)

To all whom it may concern:

Be it known that I, FRANK F. GIBEoRD,-a citizen of the United States, residing at Englewood, in the count-ylof Cook and State of Illinois, have invented certain new and useful Improvements` in Artificial-Stone(Pavements; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it -appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a partof this speciication. A

My invention has relation to` artificial-stone pavements; and the object is to provide a simple, cheap, and durable pavement, of the'class described, that will present a true surface for wear, and at the same time obviate all tendency to cracks, separation at the joints, or irregularities in the surface; and to these ends Vthe novelty consists in the construction of the same, as will be hereinafter more fully described, and particularly pointed out' in the claim.

In the accompanying drawings, the same letters of reference indicate like parts of the invention. l

Figure l is a top plan view of a sectionof my new' pavement. Fig. 2 is a reverse or bot vtom plan View of the same, and Fig. 3 is a bottom perspective view of one of the blocks.

forming the pavement. 'Y

The pavement proper consists of a series of blocks, A, provided with integral projections vI and recesses b, sadprojections and recesses being tlush with the bottom of the block and extending upyvard about one-half the thickness of the block.

The top surface of the blocks is a true square, and consequently the pavement may beextended indefinitely ,by simply alternating the sides of the blocks as they are 1aid-that is, so arranging them that a side with a projec` tion will be contiguous to a side with a-recess. It will be observed that the projections are rectangular in form, While the recesses iare inward, so that when the pavement is setin a bed or layer of cement the cement 'will till up the interstices, and when it hardens or sets make it practically a solid sheet of pavement.

- The blocks may be pressed or molded of any style of concrete, cement, or'tiling `and 'then baked, and of course may be ornainented or colored to suit the taste, and can thus be suited in their cheapest and plainest` form -to street- Walks, while the more elaborate are suitable ,Y

for all styles of tiling for halls, vestibules, mantels, and the like.

What I claim is- I As a new article ofmannfacture, a block for pavements, having two of its sides pro- A vided with projections, and its two opposite sidesprovided with recesses, as set forth.

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