PAVEMENT.

SPECIFICATION forming part of Letters Patent No. 398,055, dated February 19, 1889.

Application filed July 7, 1888. Serial No. 279,275. (No model.)

To all whom it may concern;

Be it known that I, J OHANNEDUARD KNOCHE, of San Jose, in the county of Santa Clara and State of California, have invented a new and useful Improvement in Pavements, of which the following is a. full, clear, and exact description.

This invention relates to pavements constructed mainly of hollow metal blocks or shells, which may either be left empty or be filled with concrete or other material, and which are checkered 011 their upper surfaces to prevent horses when traveling thereon from slipping, also to give the hoofs and calks of the animals a firm hold; and the invent-ion c011- sists in a novel construction of such a pavement and in a combination therewith of gutterblocks and flanged side supports to the pavement, substantially as hereinafter described, and pointed out in the claims.

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

Figure 1 represents a view in perspective of one of the pavement-blocks. Fig. 2is an under view of the same. Fig. is a transverse section thereof upon the line 0c of Fig. 1. Fig. 4: is a plan view of a metal-paved carriage-way in part, with gutter and sidewalk in part, all in accordance with my invention. Fig. 5 is a transverse sectional view of the same, and Fig. 6 is a view showing a modified construction of the flanged support which unites the arriage-way pavement with the gutter.

A indicates the carriage-way of the road, B its gutter, and one of the sidewalks in part.

Substantially similar pavement-blocks are used both for the carriageway A and the gutter B. These blocks'D, which are hollow, are each in the form of a shell, closed on their tops but open below, and made of iron, steel, or other good and suitable metal. Said blocks D may be made of any desired length, width, and depth, of parallelograinmic form, but with their sides and ends of tapering construction, so that they are of less area at theirtops than at their bottoms, and when laid side by Side or end to end leave a tapering space in between them, which may be suitably filled in with earth or other material. In changeable clin'lates strips of wood, felt, or other yielding material may be laid in between the blocks to allow for shrinkage and expansion.

In every case the ground should be suitably prepared and leveled before laying the blocks, which in the construction of the carriageway are arranged side by side crosswise of said I form on the carriage-way surface six raised portions, 12, of like area, which form a good checkered surface to preventhorses from slipping and to secure a good hold for their hoofs and calks. To economize metal in the construction of these blocks, and at the same time to give them increased strength where more strength is required, they are made of reducingthicknessin a downward direction at their sides and greater thickness at their tops. This, in conjunction with the tapering form of the blocks, combines both lightness with strength and a broad base and reduces the expense of the blocks.

To form the gutter B between the pavement of the carriage-way A and the sidewalk C, any number of. rows of the pavement-blocks D, which may, if desired, be differently grooved 011 their tops, are laid lengthwise of the gutter at any required depth, and combined with these or row of gutter-blocks next to the carriage-way A is a metal flanged support, G, to the side of the carriageway pavement, and

which stands as high above-the surface of the gutter-block as the depth of the gutter, and is flush at its top, which is rounded, withthe outer adjacent row of blocks of the carriageway. This flanged support G (sh own in section in Fig. 5) forms the edge of the gutter, where in a city the horses stand, tramp, and

paw, and it is made of suitable strength to resist such wear and tear. Said support G, which is made up in sections of suitable length, is shaped or set sloping to bear against the outer sides of the outer row of blocks composing the carriage-way, as shown in Figs. 4 and 5, said support G or its several sections either being made with a base-flange, g, as shown in Fig. 5,01 with an overlapping anglepiece, 72, as shown in Fig. 6, and serving to brace the gutter-blocks an d adjacent carriageway blocks together, and in which Fig. I said support G is cast on and integral with the 1 1 and metal flanged supports G, extending from blocks D of the carriage-way ncxtto the gutter.

A pavement constructed as described will be strong, durable, and comparatively noiseless, may readily be taken up and replaced to lay down gas, water, and other pi.pcs,including pipes for various electric wires; and if the ground on which the blocks rest be properly prepared and pressed there will beno settling of the blocks after replacing them.

Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a pavement composed of metal blocks, the metal blocks D, of shell-like construction, open at their base but having closed checkered or grooved tops and tapering downward]y-diverging sides of diminishing thick ness toward their bases, substantially as specilied.

In a street or road having a carriage-way, A, gutter B, and sidewalk C, the carriage-way and gutter pavements each composedof metal shell-like blocks D, constructed. as described,

the gutter-blocks up to the tops of the adj acent carriageway blocks and arranged to bear against the sides of the latter and to brace them and the gutter-blocks, essentially as shown and described.
