AN IMPROVED MODE OF JOINTING OR CONNECTING TOGETHER TILES AND WOODEN BLOCKS OR SLABS FOR PAVING, FOR PARQUETRY FLOORING AND FOR SIMILAR USE
Year: 1884

page_text: I, THOMAS ROBB, of Glasgow, in the county of Lanark, Foreman Joiner, do
hereby declare the nature of my said Invention for "AN IMPROVED MODE OF
JOINTING OR CONNECTING TOGETHER TILES AND WOODEN BLOCKS OR SLABS FOR
PAVING, FOR PARQUETRY FLOORING AND FOR SIMILAR USE," to be as follows:-
This Invention consists of an improved mode of jointing or connecting together
ornamental tiles for fire places, wooden blocks or slabs used for paving, wooden
squares or pieces for forming parquetry flooring, wall linings, panels, and materials
for similar use.
_ According to my Invention I cut or otherwise form in the sides of the tiles,
blocks or slabs, one or more grooves or channels both in the longitudinal and
transverse directions; and into these grooves, I fit long slip feathers, bars or strips
of wood or of metal which, when the blocks or slabs are brought edge to edge, lie
in the grooves of the adjacent blocks and serve to unite or connect them together,
so that they are kept at the same level. The grooves in the longitudinal direction
are at a different plane in the thickness of the blocks or slabs from those formed in
the transverse direction, so that the slip feathers or bars which lie in the grooves at
the longitudinal joints may be immediately over or under those which lie in the
transverse direction. Two or more grooves may be formed in the blocks or slabs
in different planes, into which the longitudinal or transverse slip feathers or bars
may be fitted.

I, THOMAS ROBB, of Glasgow, in the County of Lanark, Foreman Joiner, do
hereby declare the nature of my said Invention for AN IMPROVED MODE OF
JOINTING OR CONNECTING TOGETHER TILES AND WOODEN BLOCKS OR SLABS FOR
PAVING, FOR PARQUETRY FLOORING, AND FOR SIMILAR USE," and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
.
This Invention consists of an improved mode of jointing or connecting together
ornamental tiles for fire-places, wooden blocks or slabs used for paving, wooden
squares or pieces for forming parquetry flooring, wall linings, panels, partitions and
inaterials for similar use.
In the accompanying: Drawings which illustrate my Invention, Figure 1 is a
perspective view of a piece of improved parquetry flooring, and Figure 2 is a similar
view of a piece of paving formed by joining wooden blocks. Figures 4 and 5 are
plans of modifications.
According to my Invention I cut_or_otherwise-form-in-the-sides-of-the-tiles,
blocks, or slabs A whether of wood or other material, one or more grooves or
channels a, a¹, both in the longitudinal and transverse directions; and into these
grooves I fit long slip feathers, bars or strips b of wood or of metal which, when
the blocks or slabs A are brought edge to edge, lic in the grooves of the adjacent
blocks, and serve to unite or connect them together, so that they are kept at the
same level. The grooves a in the longitudinal direction are at a different plane in
the thickness of the blocks or slabs A from those a' formed in the transverse
direction, so that the slip feathers or bars which lie in the grooves at the longi-
tudinal joints may be immediately over or under those which lie in the transverse
direction. Two or more grooves may be formed in the blocks or slabs in different
planes, into which the longitudinal and transverse slip feathers or bars may be
fitted. As shown in figure 2 for example, one strong slip feather or bar 6 may
be fitted longitudinally between the blocks and a transverse slip on each side of it.
In some cases the longitudinal and transverse slips may be inclined to each other,
as for example when the blocks A are of diamond shape, as in figure 3, or they
may even be of zig zag form to fit the contour of hexagonal blocks. In the
example illustrated in figure 3, the main blocks A are of hexagonal form, but are
made up to a diamond shape by adding triangular pieces A at opposite sides.
The triangular pieces may either be glued, cemented or similarly attached to the
hexagonal blocks, or slip feathers 6₁ may be fitted in the lines of the joints.
Figure 4 illustrates another ornamental form in which the blocks are held together
by longitudinal and transverse slip feathers, and fitted with longitudinal straps to
suit as a border. The parquetry or paving is made up into slabs containing a
number of blocks which are fitted together singly, and the slip feathers on one or
more sides are left projecting beyond the edge of the slab, while in the next slab
the slip feathers do not extend quite to the edge, but the channels are open to
receive the projecting slips which are fitted into them to unite the slabs. This
construction presenting the same character of facing on both sides permits of either
side of the slab being used for the top.
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. The improved mode of jointing together tiles, slabs or blocks for parquetry
flooring, paving, and the like said mode consisting in uniting the blocks by the use

page_text: of slip feathers, bars, or strips fitted longitudinally and transversely or diagonally
substantially as herein set forth.
Second. The improved parquetry and paving slabs or sheets herein described and
illustrated, such slabs being formed by jointing together blocks of wood or other
3 material by means of slip feathers, bars or strips fitted in the longitudinal and
transverse joints in the manner set forth.
