UNITED STATES PATENT OFFICE.

PETER STUART, OF EDINBURGH, COUNTY OF MID-LOTHIAN, SCOTLAND.

COMPOSlTE PAVEMENT.

SPECIFICATION forming part of Letters Patent No. 269,480, dated December 19, 1882.

' Application filed May 22, 1882. (No model.) l

To all whom it may concern:

Be it known that I, PETER STUART, a citizen of the United Kingdom of Great Britain and Ireland, residing at Edinburgh, in the county of Mid-Lothian, Scotland, have. invented a new and useful Improvement in Composite Pavement,ot' which the following isa specitic-ation.

My improvement is especially, though not exclusively, intended for application to sidewalks; and it consists in the formation in the suri'a'cc ot' pavements of depressions of such a character that in stepping'thereon the pressnreot the feet will expel the air, causinga partial vacuum, which, supplementing the mechanical ei'ect of the ronghened surface, will operate to afford an additional hold to the feet and prevent slipping. This beneficial et'- fect is greater when the pavement is wet, at which time pavements as ordinarily constructed with smooth or grooved surfaces are more than usually slippery.

In the accompanying. drawings, Figure l is a plan view 0f asection of pavement illustrating my invention. Fig. 2 isa vertical section of the saine.

A represents blocks of pavement-such, for example, as described in Letters Patent of the United States No. 248,526, granted to me the 18th of October, 1881, and No. 259,059, the 6th of June, 1882.

B B represent pits or depressions, .which I prefer to form rectangular on .the upper surface and tapering downward to points, thus constituting inverted pyramids. They may, if preferred, he of round oranyother form which adapts them to operate in the manner dcscribed; but they must necessarily be of limited area, preferably not more than onefourth inch in diameter, and must be of substantially even or level margin, and without grooves or extensions, which would permit thepassage of air when the top of the aperture is covered hy the foot. They are preferably not more than half an inch apart, so that a number of them may be under the sole of the foot at once; but of course the invention -is notlimited to a spectic distance, so long as they are sufficiently near to have the effect described.

Thisinvention is applicableto artificial stone of' all kinds, and to asphaltand allother kinds of plastic or composite pavements.

Havingthus described myinventiomthe followingis what 1 claim as new therein and desire to secure by Letters Patent- A composite pavement formed With circular, square, or analogous depressions of equal or nearly equal diameter in each direction, and

with even or level margin on the pavement surface, to adapt theiu to operateiu the manner. described.y
