William Burnham Woods,
Stow v. Chicago — Opinion of the Court
“ All, therefore, that there is left for the invention described in the first and third claims to cover is the making of the lower ends of a portion of the blocks of which the pavement is composed in wedge shape, and the driving of these wedge-shaped blocks below the general under-surface of the pavement into the sand or earth-bed on which it rests, so as to pack it and render it solid and unyielding. ”
