A making a part of .the same.

Figure lis a plan view of the pavement.

- Fig. 2 is a side view. Fig. 3 is a detached section.

Like letters of reference refer to like parts in the several views.

This 4invention is a pavement for roadways, sidewalks, Sto.; and consists of an arrangement of stoneware, tubular, cylindrical blocks of a certain length and diameter, set endwise near to each other. The interstiees between them and the bore of the blocks are filled with Portland or other cement, or other suitable material.

A more 'full' and complete description of the invention is as follows: The cylindrical blocks referred to are shown in the drawings at A, the length and diameter of which may be variedas the strength of the pavement or other circumstances may determine. The materia-l whereof the blocks are made consists of fire-clay, or other ceramic clays of a suitable character, molded into the cylindrical shape shown inthe drawing, and burned Vin a kiln` in the ordinary way. Said blocks are made with a hole, B, entirely through them, thereby constituting theln of a tubular nature;

- also, a groove may be cut transversely in the end, as shown at C, and also a groove or notchone or more-may be cut around them, as will be seen at D, the purpose of which will presently be shown.

. The manner of constructing a roadway vwith the above-described blocks is as follows: The road-bed is iirst prepared with a strong and properly-graded bottom, composedof any appropriate material, whereon is then set endwise the cylindrical blocks, in tlie order as shown in Fig. l, in which it will be seen that the grooved end is upward. The blocks being thus set and arranged, the interstiees between them andthe holes B are filled with cement,

thereby forming a-compact, solid surface for a roadway.

Instead of cement, a concrete of sand, gravel, Ste., may be used. The filling between the blocks, being of a softer nature than the blocks themselves, will wear away thefastest, leaving the ends of them somewhat above the cementror filling, thereby making the surface `rough, so that Vhorses may not slip thereon.

Naturally the edges of the blocks will wear down faster than the more central part. In order to prevent them vfrom wearing to a central point is the purpose of the holes 4B in them, which, in consequence of being filled with softer material than the blocks,will leave the edges of the hole to'wear down. There being no center to form la point, theA blocks will therefore continue to be Worn down nearly, if not quite, level. The purpose of the groove C is to afford a foot-hold for the horses feet when the pavement is new, and before the filling has been so much worn out from between the blocks as to give a foot-hold to the horse by means ofthe interstiees, by which time the grooves may have been worn away and obliterated 5 the interstiees will then an swer the place of the grooves for the purpose specified. The notches or grooves D, made in the side of theblocks, are to prevent them from settling down. To this end the cement or filling will fill the grooves or notches, thereby offering a shoulder for resisting the downward tendency of the blocks when subjected to any unusual or extraordinary pressure from above.

In using the above blocks for sidewalks, or`

other foot-pavements, the cementitious filling of the material specified, and arranged as set burned in a kiln or otherwise, for roadways forth, and the interstioes between and the hole and foot-pavements, as herein set forth. or bore of said blocks llerl with cement or other material, in the manner as and for the WILMOT H. GARLICK. purpose set forth. l/Vitnesses:
