COMPLETE SPECIFICATION.
Improved Blocks for Flooring or other purposes.
I, EDWARD GREGORY, of 6, Clarence Villas, St. Mary's Grove, Richmond, in
the County of Surrey, late Surveyor War Department, 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:-
The blocks according to my invention are made as hereinafter explained so that
they overlap at their edges in such manner that the blocks are cach held down by
Four adjacent blocks and each also holds down four adjacent blocks. The said blocks
may be made of wood or other material according to the purpose for which they are
to be isl.
Figure 1 represents in plan and Figure 2 in edge view a rectangular block made
according to my invention and Figure 3 shews how they may be laid. Figures 4,
5 and 6 are similar views of a lozenge shaped block. Each block has on
two of its opposite sides projections a a below the upper surface of the block
and the other two sides of the block have projections above the lower
surface of the block. The thickness of the projections are as shewn in Figures 2
and 5 one half the thickness of the block, the lower surface of the projections a a
being flush with or a continuation of the under surface of the block and the top
surface of the projections & being flush with or a continuation of the upper surface
of the block so that the top and bottom surfaces are alike and may be laid with
either side uppermost.
For flooring I prefer to make the projections & which are flush with the upper
surface of the block thicker than the projections a as shewn in Figure 2ª to allow
for wear.
When the blocks are placed together as shewn in Figures 3 and 6 it will be
seen that in each case the projections of each block hold down four adjacent
blocks by overlapping the projections a thereof whilst each block is held down by
the projections 6 of four adjacent blocks engaging the projections a a thercon.
As shewn for example in Figures 3 and 6 the projections on the block A' holds
down the four adjacent blocks 1. 2. 3. 4 by overlapping their projections a² a² a³ a
and the block A' is itself held down by the projections 62 6868 of the
The blocks
blocks 1. 3. 5. 6 overlapping the projections a a on the block A'.
may be bedded on concrete as shown at c in Figure 7 and they may be further
secured in place by cement or by nails or by both the nails as shewn at d being
driven through projections a of the blocks which come opposite or over ribs e
which ribs may be embedded in the concrete c after the manner of what are known
as Wright's fixing blocks."

page_text: Figures 8 and 9 are a plan and edge view of a block having projections on two
adjacent sides below and above instead of on two opposite sides as in Figures 1
and 4.
In place of all the blocks being of the same size as in Figure 3 blocks B of the
same shape as, but of smaller size than the blocks A may be laid with the larger
blocks as shewn in Figures 10 and 11. In this case each of the large blocks, for
example A is held down by four adjacent large blocks 1, 2, 3, 4 and two adjacent
small blocks B, and each large block (see block A') holds down four adjacent large
blocks 1, 2, 3, 4 and two small blocks B³. I have shown the contact surfaces of
the projections a and b parallel to the face of the block but they may be at an
angle thereto if desired.
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:-
1st. Blocks for flooring or other purposes made with two sides projecting from
above and two sides projecting from below substantially as and for the purpose
hereinbefore described and illustrated on the accompanying sheet of drawings.
2nd. For flooring and other surfaces blocks of wood or other material constructed
and arranged substantially as hereinbefore described and illustrated in Figures 1,
2, and 3, Figures 4, 5 and 6 and Figures 10 and 11 of the accompanying
drawings.
