The roadway is first prepared by the removal of the present paving and surplus
earth, and on the bottom, after being properly formed and levelled, a foundation of
four inches, more or less, of clean sand is laid thereon. On that the wooden blocks
are placed in rows across the street, between each row a wedge or wedges are firmly
driven until they penetrate the sand or earth to the depth of, at least, three inches,
thereby compacting the sand firmly about and under the blocks and thoroughly
wedging the blocks and rows, besides leaving a space between each row of blocks to
provide for the contraction and expansion of the blocks, and also giving a foothold
to the horses travelling over its surface. After the wooden blocks are laid and
wedged the crevices left above the wedges are filled with concrete and thoroughly
rammed. The whole surface is then floated with heated coal tar and clean sand
spread over it, forming a concrete surface, taking every precaution to make the
surface water-tight.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent, and
of an Order of the Lord Chancellor, by the said Charles Henry Green in the
Great Seal Patent Office on the 6th December 1876.

"
IMPROVEMENTS IN WOOD PAVING." A communica-
tion from abroad by Barzilla Foster Bond, of Brooklyn, in the State of New York,
and United States of America.
This Invention relates to improvements in wood paving, the following being a
description thereof :-
After the roadway is prepared by the removal of the old pavement and the
surplus earth to a proper depth to bring the surface of the now pavement when
laid to the desired grade, a foundation of about six inches of sand is laid, on that
wooden blocks of any desired thickness and depth, but preferably of the dimensions
of three inches in thickness, six inches in depth, and any convenient width, are
placed on end in rows across the street, between each row of blocks a wedge or
wedges, preferably six inches wide, and of any convenient length, and one inch or
one inch and a quarter in thickness, are placed, and when a sufficient number of
rows of blocks are laid to resist the pressure the wedges are driven down into the
sand foundation to the depth of about four inches, thus compacting the sand under
and about the blocks to nearly the consistency of stone without destroying its
elasticity or power of absorption, and leaving a space between each row of blocks
to give a foothold for the horses' feet, and to provide for the contraction and
expansion of the wood. After the blocks and rows are thus wedged the crevices
above the wedges are filled with concrete, asphalte, or other material, as may be
thought best, but preferably of concrete or asphalte. The surface is then ready to
receive any dressing that may be desired, but I prefer to flood it with heated coal
tar, with clean sand spread over it, forming as far as possible a water-tight surface.
The pavement is then complete and ready for usc.
Having thus described the said Invention, and the manner of carrying the same
into effect, I wish it understood that I claim the alternation of the blocks and
wedges in combination with the sund foundation, substantially in the manner as
and for the purposes herein-before described.
In witness whereof, I, the said Charles Henry Green, have hereunto set my
hand and seal, this Thirtieth day of November, in the year of our Lord One
thousand eight hundred and seventy-six.
