GUSTAVUS A. ASOHBACH, OF NElV YORK, N. Y.

IMPROVEMENT IN CONCRETE AND TlLE PAVEMENTS.

To all whom it may concern:

Be it known that I, GUSTAVUS AnoLrrrUs ASOHBAOH, of the city, county, and State of New York, have invented a new and useful Improvement in Concrete Pavements; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanyingdrawin g forming part of this specification, in which drawing Figure 1 represents a plan or top view of my pavement. Fig. 2 is a plan View of the tiles used in the formation of the borders of the blocks or sections of my pavement in a larger scale than the previous figure. Fig. 3 is a sectional side view of two of these tiles.

Similar letters indicate corresponding parts.

This invention consists in a concrete pavement laid in detached sections or blocks, each block being confined within a border formed oftiles in such a manner that in laying the pavement the spaces for the reception of the sections of the pavement can be readily defined, thus allowing of laying a number of sections at the same time, and, furthermore, each section can be readily taken up and relaid without disturbing the adjoining sections 5 also, in the combination of circular or semicircular tiles with oblong tiles, the ends of which are concave to fit the peripheries of the semicircular or circular tiles in the formation of borders for blocks or sections of a concrete pavement in such a manner that, by combinin g the circular or semicircular tiles with the oblong tiles, borders of many different forms can be produced, and at the same time tight joints are produced between the adjoining tiles in whatever direction the oblong tiles may be placed in relation to the circular or semicircular tiles.

In the drawing, the letter A designates a circular tile, the letter B a semicircular tile, and the letter (J an oblong tile of that description which I use in the formation of my borders for sections of concrete pavement. These tiles are made of clay or any other suitable material, and the ends of the oblong tiles are made concave, as shown in Fig. 2, so that the same will fit the periplr eries of the circular or semicircular tiles, and that tight joints will be produced between the adjoining tiles. The semicircular tiles are placed with their rectilinear sides against thecurbstones or walls which inclose the pavement. The oblong tiles may be made with one concave and with one square end, if they are to be laid against the curbstonc or walls, or, if such is desirable, for the purpose of producing borders of certain shapes. The sharp corners of the concave ends of the oblong tiles are chamfered off, as shown in Fig. 2. The sides of my tiles are either square or slightly sloping from the bottom toward the top, and said tiles are provided with notches a I), either in their ends or centers, to facilitate their adjustment 011 the ground.

Before laying down my tiles, I paint their ends'with coal-tar, asphaltum, or an equivalent material, and, after they have been laid and adjusted in the proper position by means of pattern-frames and strings, the spaces between them are filled with the most approved plastic mixture known for the purpose of making pavements. A pavement thus laid will permit the taking up of single sections and the renewing and relaying of the same without interfering with the adjoining sections furthermore, the progress of the work of laying the pavement will be hastened, as a number of blocks or sections to be formed of concrete can be worked at once. Besides this, my borders increase the durability of the pave ment, and impart to the same a novel and ornamental appearance.

\Vhat I claim as new, and desire to secure by Letters Patent, is

l. The combination of borders formed of tiles with the sections of a concrete pavement, substantially as described.

2. The combination of circular and semicircular tiles with oblong tiles having concave ends in the formation of borders for a sectional concrete pavement, substantially as set forth.
