Improvements in Paving-blocks.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of London,
Patent Agent, do hereby declare the nature of this invention (a communication to me
from abroad by Phineas Arnold, of Canal Dover, Ohio, U.S.A., Inventor) to be as
follows:-
:-
This invention relates to certain new and useful improvements in the construction
of paving-blocks; and it consists in providing a block on one of the vertical sides
thereof with a horizontal channel, which is intersected by two vertical channels
which extend to the upper portion of the block, the end of said block having
horizontal en channels of less depth than the channels on the side of the block,
as will be hereinafter fully set forth, whereby I am enabled, by the use of cement
or other binding material, to scare the blocks firmly to each other, the upper
edges of the block heing beveled for the purpose of providing a conduit into
which the cement or binding material may be poured to fill the vertical and
horizontal channels, as well as provide a foothold for draft animals.
In the accompanying drawings,
Figure 1 is a perspective view of a portion of a pavement constructed with my
improved blocks, and
Figure 2 is a sectional view of two of the blocks placed adjacent to each other.
A refers to one of my improved blocks, which is preferably inade of fire-clay or
other composite material adapted to he used for street pavements or roadways, and
these blocks A, in constructing a pavement, are laid so that the joints will be broken
and the face of one block will be adjacent to the back of the other, thereby rendering
necessary only to groove or recess one of the faces. The upper corners or edges of
the block are rounded or bevele 1, as shown at a, and one of the long faces or sides is
provided with vertical recesses or grooves A', which intersect a horizontal groove or
recess B, which is located about midway between the bottom and upper face of the
block. The vertical grooves or recesses A' and the horizontal groove B are of
considerable depth, and the end or ends of the block are provided with horizontal
recesses B', which are of less depth than the recess B. These horizontal recesses B¹
may be on each end of the block when they are comparatively shallow, or only on one

page_text: end when they are of the same depth as the recess B. These recesses are formed in
the paying-block when the same is moulded.
In laying a pavement with my improved blocks they are placed upon a suitable
foun-lation end to end, so that one of the long vertical sides will be on the same line,
and the next row of blocks is alapted to break joints therewith. After the blocks are
properly laid in position, a binding and waterproofing pterial-as asphalte, comment, or
other suitable material which will harden-is poured into the channels formed by the
heveled edges a, and passes through the recesses or duets a' into the horizontal
channels Band B, so as to bind the blocks securely to each other and make them
water-tight. As the blocks when first laid are placed closely to each other, but a
small amount of cement or asphalte will le required to fill the grooves or recesses, as it
will not pass below the horizontal channels in the paving-blocks.
I am aware that prior to my invention it has been proposed to provide a rectangular
paving-block with horizontal grooves or corrugations and an upper beveled edge, a
pavement made of such blocks being a lapted to he held together by cement; but in
this case, as the blocks sit quite a distance from each other, a large quantity of cement
has to be used, as it is not only required to fill the horizontal grooves or corrugations,
but also a space between each of the fees of the block, and in addition to the
excessive quantity of material a large amount will pass beneath the paving-block,
where it answers no usefni purpose.
I am also aware that a concrete paving-block has been provided having a horizontal
groove on one or more faces, intersected by a vertical groove, said grooves being for
the purpose of permitting the insertion of a suitable implement, so that the blocks can
be removed when necessary for making repairs.
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:
1. A rectangular paving-block made up of moulded material and provided on
one of its sides with a horizontal groove or recess intersected by vertical grooves
or recesses A'. the ends of said blocks having rocesses B. and a smooth sile, the
upper edges of the blocks being rounded or beveled, substantially as and for the
purpose set forth.
2. A rectangular. paving-block made up of moulded material and provided with
a heveled upper edge and a smooth vertical side or face, vertical grooves or duets A',
intersecting a central horizontal groove or recess B, and shallow end recesses B³,
connecting with a groove or recess B, said blocks being adapted to be laid sub-
stantially as shown. so that they will abut against each other, the grooves A, B,
and B being adapted to he filled with a binding untorial, substantially as and
for the purpose set forth.
