An Improved System of Street or Floor Paving.
I PEARSON JACQUES JACKSON of 17 Grainger Street in the City and County,
of Newcastle on Tyne, Advertising Contractor, do hereby declare the nature of
this invention 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 an improved system of street or floor paving.
The foundation for my improved paving may be prepared in the usual way with
a bottoming of broken stone over which may be laid a concrete bed, thus forming
a solid as well as a comparatively level surface.
The improved paving consists of an alternation of wood and concrete surfaces
arranged in more or less equal areas and to effect this I form wooden blocks,
which may or may not be creosoted of for example an oblong form with alternating
solid and hollow spaces.
To fully explain my invention I will now refer to the accompanying drawings in
which
Figure 1 shows in side elevational view the general form of the wooden blocks,
Figure 2 being a plan view of a piece of paving arranged and built according to
my invention.
Figure 3 shows an end view of four wooden blocks in position.
It will thus be seen on reference to the drawings, that each block consists of.
a series of solid wooden sets A arranged so as to form a similar series of hollow
spaces A¹ and that when the blocks are ranged in position as shown in Fig. 2 the
solid wooden spaces in one block come opposite corresponding hollow spaces in the
adjoining blocks.
Thus to form a pavement or floor according to my invention I firstly place a
sufficient number of the blocks in position on the concrete bed and then I fill in
all the hollow spaces with cement grout or with cement concrete in a fine state
until the whole forms a solid pavement or floor.
The size of the blocks may vary but about 10" x 6" x 3" is a suitable size for
ordinary pavements, the hollow spaces measuring about 1" wide x about 4" down-
wards from the top of the block thus leaving about 2" of solid wood at the block
bottom.
If desirable, the sides of the hollow spaces may be "roughed " to give the cement
a better grip.
Where cost is not a matter of much consideration, the hollow spaces may be
filled in with india rubber or gutta percha instead of cement concrete.
In this manner a comparatively noiseless pavement embodying greater durability
than ordinary wooden paving may be obtained.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved compound paving for streets or floors consisting in the formation
and arrangement of wooden paving blocks so as to form a series of alternating
wooden block surfaces and hollow spaces or interstices the hollow spaces or inter-
stices being filled with cement grout or concrete or india rubber or gutta percha

hereinbefore set forth.
