ments I fix fillets to the boards which form: the sides of the first laid blocks, so that the
sides of these blocks have a groove or grooves formed in them. Preferably I use two
fillets for each side a rectangular one at the top and a triangular one about half way
down. The concrete of the second series of blocks enters the triangular grooves in
the sides of the blocks first laid and thereby supports the points between the blocks.
Before putting in the concrete and cement for forming the remaining blocks I place a
bar of wood in the top groove, the bar being of twice the thickness of the fillet by
which the groove was formed. the result is that the remaining blocks have a similar
groo.e formed at the top, the two grooves together forming in the surface of the pave-
ment a single groove open at the top. In order to make the joint between the blocks
water tight I place a bar of wood in this groove with a caulking of red lead or a filling
of suitable cement.

I, PETER STUART of Church Row Limehouse, in the County of Middlesex Pavior
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 that class of concrete and cement pavements which are laid
in squares (or other figures) every alternate square being first laid and then allowed to
dry and harden before the remaining squares are filled in. In laying such pavements
I fix fillets to the boards which form the sides of the first laid blocks, so that the sides
of these blocks have a groove or grooves formed in them. Preferably I use two fillets
for each side a rectangular one at the top and a triangular one about half way down.
The concrete of the second series of blocks enters the triangular grooves in the sides of
the blocks first laid and thereby supports the points between the blocks. Before putting
in the concrete and cement for forming the remaining blocks I place a bar of wood in
the top groove the bar being of twice the thickness of the fillet by which the groove
was formed the result is that the remaining blocks have a similar groove formed at the
top, the two grooves together forming in the surface of the pavement a single groove
open at the top. In order to make the joint between the blocks water tight I place a
bar of wood in this groove with a caulking of red lead or a filling of suitable
cement.
In order that my said invention may be more fully understood and readily carried
into effect I will proceed to describe the drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
The drawing shows a vertical section of a pavement in process of construction
according to my invention.
A. A. are two boards forming the sides of the mould into which the block of
concrete; B has just been run. The boards A have fixed to them two fillets and D.
The fillet C is preferably rectangular and D triangular as shewn. On the right hand
side of the drawing is seen a block of concrete F from which the moulding boards
have been removed and a piece of wood F put into the groove at the top of the block
which was formed by the rectangular fillet. When the block B has hardened the
boards A A. are removed and bars of wood similar to F put into the notches now
occupied by the rectangular fillets C. C. The blocks B and E together with the
similar blocks back and front not shown in the drawing all provided with bars F from
the mould for an intermediate-block. When this is set the hars of wood Fare removed
leaving all round the blocks a groove. This groove is filled with a piece of wood
caulked with red lead, or a filling of cement or any other material,

page_text: 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 [
claim is :-
1. A pavement of the class specified in which grooves or recesses are formed
in the sides of the blocks to receive projections on the adjacent blocks substantially as
described.
2. A pavement of the class specified which is grooved on the surface at the
junctions between the blocks to receive a filling or stopping substantially as described.
3. A pavement substantially as described and shown in the drawing.
