I WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN PAVEMENTS and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to pavements, and comprises improvements substantially
as hereinafter described.
In the accompanying drawing
Figure 1 is a perspective view of the improved pavement,
Figure 2 is an end elevation drawn to an enlarged scale, and
Figure 3 is a perspective view of a base plate, also drawn to an enlarged scale.
The base-plates D are made of any suitable material. They may be of cast metal
and the ribs a cast integral with them, or if preferred the ribs may be formed by
pressing, or striking up plates of metal with a die.
The two outside ribs c. c of each plate are made of about half the thickness of
the ribs a a. This arrangement is illustrated in Figures 1 and 2, in which recesses
formed in the under sides of the blocks B B, are shewn as fitting over the thin
ribs cc of two contiguous plates D, thus detachably locking the plates together by
the pavement blocks.
The blocks B, and plates D are so proportioned and laid that the joints between
the blocks will not coincide with the joints at the abutting ends of the ribs, so that
the said blocks lock a row of plates from lateral displacement.
The blocks are sometimes of such thickness that a space is left between them,
into which space gravel or other suitable material may be filled; the blocks may,
however, be of such a thickness that they will touch each other when in place.
In Figure 3, one of the base plates is shown having perforations through the
bottom between the ribs, to allow water and dampness to leak through to the
ground below the base-plate.
The size of the blocks B, and of the plates may vary according to requirements
and convenience. It is advantageous to make them of a size suitable for handling
and shipping

page_text: A pavement constructed according to this invention is cheap owing to its
simplicity, and the ease with which it is laid, and a strip may be readily taken up
for the purpose of laying a channel or the like owing to the parts being detachably
locked in such a simple manner.
By removing a row of blocks from the abutting ends of the ribs, a a, c c, at
desired points and taking up the intermediate blocks a strip or portion of the
pavement can be readily taken up.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
First. In a pavement, a series of blocks having grooves or recesses in their under
sides, and a series of ribbed base-plates having the ribs on the sides contiguous to
each other of substantially half the thickness of the width of the grooves in the
blocks, whereby the base-plates are detachably locked together, substantially as set
forth.
Second. The combination of the ribbed base-plates having the contiguous ribs
thinner than the intermediate ribs, and blocks having recesses in the under sides,
the joints between the ends of which blocks alternate with the joints between the
abutting ends of the ribs, the recessed blocks fitting over the thin contiguous ribs,
substantially as set forth.
Third. In a pavement composed of base plates and blocks, the base plates
having perforations through them, substantially as set forth for the purpose
specified.
