IMPROVEMENTS IN PAVEMENTS, WALL SURFACES AND OTHER LIKE SURFACES
Year: 1884

page_text: "
I, JOSEPH HENRY CHAVASSE of the Cedars Kingswinford in the County of
Stafford Coal Master, do hereby declare the nature of my invention for
IMPROVEMENTS IN PAVEMENTS, WALL SURFACES AND OTHER LIKE SURFACES," to
be as follows:-
In the ordinary method of constructing pavements, wall surfaces, and other like
surfaces, the tiles quarries or bricks employed are generally either square or
polygonal in figure, and the lines of junction are right lines. As a consequence
the junctions of the pavement, wall or surface are weak and yield to moderate
pressure applied on opposite sides of the junction lines. Pavements walls and
surfaces so constructed are very liable to injury; a slight pressure or percussion
sufficing either wholly to detach or to loosen the part or parts pressed or struck.
My invention consists in building or constructing pavements walls and other like
surfaces by the use of tiles, quarries, bricks or blocks the edges of which are for the
most part arcs of circles.
Thus in making a pavement according to my invention I take quarries or paving
tiles of a triangular figure, the longest side being a convex circular arc and the
shorter sides similar concave arcs. Quarries or tiles of the kind described fitted
together form a pavement all the junctions of which are curved; which pavement
possesses a high degree of strength and readily resists pressures and blows which
would break a pavement baving straight junctions.
As pavements are usually bounded by straight lines, I employ quarries or paving
tiles for the marginal portions of the pavement having concave curves on their
inner edges so as to fit the convex edges of the other tiles and their outer edges
straight so as to fit the wall in which the pavement terminates. The opposite
edges of the pavement terminate with tiles having their curved edges convex.
Tiles having the figures of one half of each of those last described are required in
some cases and in other cases tiles having only one curved edge and two plain edges
are necessary.
I connect the quarries or tiles by the ordinary compositions or cements used for
like purposes.
The application of my invention to wall surfaces and other surfaces differs in no
essential respect from its application to pavements as herein described.
Dated this 3rd day of January 1884.

page_text: I JOSEPH HENRY CHAVASSE of the Cedars, Kingswinford, in the County of
Stafford Coal Master do hereby declare the nature of my invention for
"IMPROVEMENTS IN PAVEMENTS, WALL SURFACES AND OTHER LIKE SURFACES
and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
In the ordinary method of constructing pavements, wall surfaces and other like
surfaces, the tiles, quarries or bricks employed are generally. either square or
polygonal in figure and the lines of junction are right lines. As a consequence
the junction of the pavement, wall or surface are weak and yield to moderate
pressure applied on opposite sides of the junction lines. Pavements, walls and
surfaces so constructed are very liable to injury, a slight pressure or percussion
sufficing either wholly to detach or to loosen the part or parts pressed or struck.
My invention consists in building or constructing pavements, walls and other
like surfaces by the use of tiles, quarries bricks or blocks, the edges of which are
for the most part arcs of circles.
Thus, in making a pavement according to my invention I take quarries or paving
tiles of a triangular figure the longest side being a convex circular arc and the
shorter sides similar concave arcs. Quarries or tiles of the kind described fitted
together form a pavement all the junctions of which are curved which pavement
possesses a high degree of strength and readily resists pressures and blows which
would break a pavement having straight junctions.
As pavements are usually bounded by straight lines I employ quarries or paving
tiles for the marginal portions of the pavement having concave curves on their
inner edges so as to fit the convex edges of the other tiles and their outer edges
straight so as to fit the wall in which the pavement terminates.
The opposite
edges of the pavement terminate with tiles having their curved edges convex.
having the figures of one half of each of those last described are required in some
cases and in other cases, tiles having only one curved edge and two plain edges are
necessary.
Tiles
Figure 1 of the accompanying Drawing represents a couple of quarries or
pavement tiles constructed according to my invention and Figure 2 represents a
portion of a pavement made up of quarries or tiles of the kind represented in
Figure 1 but drawn to a sinaller scale. Each of the said quarries or tiles has a
triangular figure with curved sides, the longest side a being a convex circular are
of about 120 degrees, that is, one third of a circle, and the shorter sides b, b being
concave arcs of the same radius as the arc a the concave sides b, b of two adjacent
tiles forming a concave circular are similar to the convex circular arc a of the longest
side of the tile as will be understood by referring to Figure 2. It will be seen by
an examination of the said Figure 2 that when tiles of the kind Figure 1 are fitted
together to form a pavement all the junctions of the tiles are curved, the said
pavement thereby possesses the qualities herein before referred to.
Figures 3, 4, 5, 6, 7, 8, 10 and 11 represent borders or marginal parts to be used
with pavements constructed according to my invention, the said marginal parts
having concave curves on the inner edges to fit the convex edges of the tiles and
the outer edges of the marginal parts having straight edges to fit the wall in which
the pavement terminates.
In Figure 3, the border is composed of tiles a of the kind represented in
Figures 1 and 2 combined with the marginal tiles c and d, the convex curved edges

page_text: of each of the marginal tiles c fitting the shorter concave sides of two adjacent
tiles a and the concave curved edges of the other marginal tiles & fitting the halves
of the convex sides of two adjacent tiles a.
Or the border may be composed of the marginal tiles c and d, Figure 3, without
the triangular curved tiles a as represented in Figure 4. Or the arrangement
represented in Figure 4 may be doubled as represented in Figure 5.
Or the tiles d
with their straight edges face to face in conjunction with two rows of the tiles a, a
and the tiles c may be used to form the border as represented in Figure 6. Or the
tiles c with their straight edges face to face may form the middle part of the border
and the single tiles the outer edges of the border in conjunction with the
triangular curved sided tiles a as represented in Figure 7. Or the tiles c and
tiles & may be combined together without the tiles a in the manner represented in
Figure S.
Figure 9 represents a portion of a pavement composed of the triangular curved
tiles a in conjunction with small or half tiles h, h having two curved edges and a
straight edge, one of the curved edges being concave and the other curved edge
convex, the tiles h being fitted between the triangular curved tiles a in the manner
represented. The border at in Figure 9 is made up in the manner before described
and represented in Figure 7, but the border at k Figure 9 is composed of the
triangular curved tiles a and other smaller triangular tiles having two straight
edges and a curved edge, that is, having the figure of one half of the tiles c
represented in Figures 3, 4, 5, 6, 7 and 8.
Figure 10 represents another border made up of the tiles c and d in combination
with halves (Figure 9) of the triangular curved tiles. Figure 11 represents
another border made up of the series of halves h of the triangular tiles arranged in
the manner represented.
I connect the quarries or tiles by the ordinary compositions or cements used for
like purposes.
The application of my invention to wall surfaces and other surfaces differs in no
essential respect from its application to pavements as herein described and
illustrated in the drawings.
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 Making pavements, wall surfaces and other surfaces wholly or in part of
tiles, quarries, bricks or blocks their edges being either all circular ares of about
one hundred and twenty degrees, that is, one third of a circle, or one or two only
being circular ares the other edges being straight substantially as berein before
described and illustrated in Figures 1, 2 and 9 of the accompanying Drawings.
Secondly Combining with pavements wall surfaces and other surfaces claimed
in the first claim, borders or marginal parts made up wholly or in part of tiles
quarries bricks or blocks having the figure of segments of circles combined with
triangular tiles or tiles having one two or three curved sides substantially as herein
before described and illustrated in Figures 3, 4, 5, 6, 7, 8, 9 10 and 11 of the
accompanying Drawings.
