PROVISIONAL SPECIFICATION.
An Improved Paving-stone.
I, JEAN LEUBA, of Lausanne, in the Republic of Switzerland, do hereby
declare the nature of this invention to be as follows:-
The invention consists of an improved paving-stone formed in two parts, one of
which is made in the form of an open box of variable shape or configuration and of
hard material, the other one being a filling of asphalt or of a combination of asphalt
and other materials.
According to one form or modification, my invention consists of a box, open at
its top and formed of cast iron, baked clay, cement or any other suitable material
and having its inner walls shaped so as to retain the filling of asphalt or a combination
of asphalt and other materials contained therein.
The outer shape of the box will preferably be a regular one as for instance
a square, an octagon or other shape and its height will be determined according to
circumstances.
The filling of asphalt or a combination of asphalt and other materials will either
be made to project over the plane of the edges of the hard box, or to form a plane
surface with the said edges or to cover the said edges so as to have the top of the
paving-stone forming with the top of the adjacent paving-stones a continuous
asphalt-surface.
The filling of asphalt may be fixed into the box of hard material in any suitable
for instance, by making the inner walls of the latter inclined.

Figure 3 is a plan of a modified form of my improved paving stone and
Figure 4 is a section of such modified form.
According to oue form or modification of my invention shown in Figures 1
and 2 my improved paving stone or block consists of a box A, open at its top and
-

its inner walls A' shaped so as to retain the filling of asphalt or a combination of
asphalt and other suitable materials therein.
The outer shape of the box will preferably be a regular one as for instance a
square, an octagon or other shape and its height will be determined according to
circumstances.
The filling B of asphalt or a combination of asphalt and other materials will
either be made to project over the plane of the edges of the hard box A, as shown
in the drawings, or to form a plane surface with the said edges or to cover the said
edges so as to have the top of the paving-stone forming with the top of the adjacent
paving-stones a continuous asphalt-surface.
The filling of asphalt may be fixed into the box of hard material in any suitable
manner as for instance, by making the inner walls of the latter inclined as shown in
the drawings. The modified form of paving stone or block shown in Figures 3
and 4 is constructed substantially in the manner above described but in this case
having a square shape.
I wish it understood that I do not limit myself to the precise form or shape of
the paving stones shown in the drawings as the said stones may be varied in shape
without departing from the spirit of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
A paving stone or block consisting of a box composed of metal, baked clay,
cement or other material and a filling of asphalt, or a compound of asphalt and
other material, the said box having its inner walls shaped so as to retain the said
filling in place, substantially as described.
