TO ALL WHOM IT MAY CONCERN: p

' Be it known that I, BENJAMIN F. MILLER, of the' city and State of New York, have invented and made a certain new and useful Improvement in Pavements for streets and roads; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had tothe annexed drawing,

' making part of this speeiication,wherein'- Figures 1 to 5 are plan views, representing my invention in the Vdifferent forms in which it may be employed, and

Figures 6 to 10 are sections of the' pavement at the line a: showing the forms corresponding to those in the plan views.

Similar marks of reference denote eorresppnding parts. ff

The Vnature of. my said invention consists in prismatie sleepers, laid with their 'angles forming ridges, betweu which the lines ,of blocks are placed, in order that each block may have a bearing upon two sleepers, and thereby be better supported, in consequence of the bearing being more extended, and the block-s, being drivenV by the weights down into .the angle between the said sleepers, are less liable to work loose than those l laidiupon a flat surface. l My invention is particularly adapted to wooden pavements, but I am not limited as to the material I employ.

The foundation ofmy pavement is made of prismatie sills, a a, laid together so that an angle or ridge forms the highest part between a trough-shaped depression. Y

' These sills are to be laid upon the usual earth or sand, or they may be laid'upon any other support; and they may be laid longitudinally of the street; Vbut I prefer to place them transversely. v

-The superstructure laid upon said sills is composed of blocks that pass into the ang-le formed between-the two sills, so as to bear upon each. i

In the drawing, figs. 1 and 6, diagonal blocks, b, as shown in my patent of April 23, 1867, are represented as laid at an inclination, and the sillsA lap under one another, as shown, so that weight upon one block is distributed over several blocks, and upon two or more of the sleepwers` I In` igs. 2 and 7, similar inclined blocks, b, are placed upon the sleepers, but strips of board or plank, c, are introduced between the ranges oi' blocks, with the grain parallel, or nearly so, with the surface ofthe pavement, sothat the edges of such strips, wearing more rapidly than the blocks, will leave depressions in the surface, and give a better foot-hold to'horses, 85e.

In figs. 3 and 8, vertical blocks, d, are shown as formed with double inclined lower ends setting between the sleepers, and with lint upper ends to form the roadway. 'Ihcse take a'bearing upon the two contiguous sleopers.- i i In figal and 9, the pieces of board or plank c, set up odgewise between the blocks d, are shown as ruiming erosswise'to thc sills a; and in figs. 5 and IO the sanic plank is shown as ruiming lengthwise over the angle of the sleeper, and between the blocks.

What I eiaiin, and desir`e`to sceurc by Letters Patent, is-

'lhe prismatie sills, laid as specified, and receiving the block superstructure, substantially as set forth.

In witness whereof, I have hereunto set my signature, this eighteenth day of February, 1868.

' B. If. MILLER.
