I, WILLIAM LLOYD WISE of No. 46 Lincoln's Inn Fields, in the County of
Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature of
this invention (a communication to me from abroad by P. M. Petersen of Copenhagen
in the Kingdom of Denmark,) to be as follows:-
This invention relates to a construction of parquet flooring in which the usual
boarding under the parquet flooring is or may be dispensed with, and the disadvantages
attaching to the usual system are obviated.
Boarding heretofore used under parquet flooring readily becomes warped and
uneven, partly because of the wood not being thoroughly dry when laid down, and
partly because of the absorption of moisture arising from various causes, whereby the
parquet flooring is affected.
The present improvements are designed to obviate these disadvantages, as the flooring
is laid directly upon beams.
The annexed drawing shows in Fig. 1, the improved construction of parquet
flooring as seen in plan. Fig. 2 is a vertical section.
Fig. 3 is another vertical section drawn to a larger scale.
a a are the main beams upon which the improved flooring is laid. This flooring
comprises transverse pieces b placed at a distance apart proportionate to the size of
the blocks or filling pieces (hereinafter referred to) employed.
The cross pieces c are mortised into the transverse pieces b, and are at right angles
to them.
The pieces b and c form together a series of rectangular openings d d.
The four sides of the pieces b and c that form each opening are each formed with a
groove.
The openings d are filled with blocks or filling pieces that may be of fir or other
hard wood.
The blocks are grooved on their edges to correspond with the grooves in the sides
of the pieces b and c.
Parquetry which may be about 3" thick is firmly glued upon these blocks or filling
pieces; it may be of various woods and may be arranged to form any desired

page_text: pattern, such for instance as either of the two patterns shown on the right hand side
of Fig. 1.
The spaces over the pieces b and c between the blocks are filled up with hard
wood.
The flooring is pieced together in the factory to form flooring of any desired area,
and may be thoroughly finished before being laid down, so that the operation of
laying down requires very little time; which is often of considerable advantage,
in such cases for example as when it is required to change or relay a parquetry floor
which is in constant use.
The flooring is fixed to supporting beams by means of screws that pass through the
projecting lower portion of the outside transverse piece, before the adjacent surface is
laid down.
The same is done at the bottom panel along the outside edge of the flooring.
When necessary, certain parts of the parquetry over the pieces b and c instead of
being glued thereto in the factory may be glued after the flooring has been laid down
and has been fastened to the beams by screws passed through the pieces b and c at
those spots where such parts of the parquetry have not been fixed.
As the boarding usually employed is dispensed with the improved parquetry flooring
according to this invention can be made much cheaper than the floorings constructed
as heretofore, and it is also more even.
The improved flooring may if desired be laid upon the usual boarding. In this case,
the pieces b and c may be of weaker scantling than when no boarding is already laid
down.

I, WILLIAM LLOYD WISE, of No. 46 Lincoln's Inn Fields, in the county of
Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature of
this invention, (a communication to me from abroad by P. M. Petersen, of Copen-
hagen, in the Kingdom of Denmark) 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 a construction of parquet flooring in which the usual
boarding under the parquet flooring is or may be dispensed with, and the disadvantages
attaching to the usual system are obviated. Boarding heretofore used under parquet
flooring readily becomes warped and uneven, partly because of the wood not being
thoroughly dry when laid down, and partly on account of the absorption of moisture
arising from various causes. The shrinking or warping of the boarding may affect
the parquetry above it.
The present improvements are designed to obviate these disadvantages, as the
flooring is supported on beams or joists, and not upon boarding.
Referring to the illustrative drawing filed with my Provisional Specification,
Fig. 1 shows the improved construction of parquet flooring as seen in plan.
Fig. 2 is a vertical section, and
Fig. 3 is another vertical section drawn to a larger scale.
a, a, are the main beams upon which the improved flooring is laid. This flooring
comprises transverse pieces 6 placed at a distance apart proportionate to the size of
the blocks or falling pieces (hereinafter referred to) employed.
The cross-pieces c are mortised into the transverse pieces b, and are at right angles
to them.
The pieces b and c form together a series of rectangular openings d, d. The four
edges of the pieces b and c that form each opening are each formed with a groove.
The openings d are filled with blocks or filling pieces that may be of fir or of harder
wood, if desired. The blocks are grooved on their edges to engage with the grooves
in the sides of the pieces b and c.
Parquetry which may conveniently be about 3" thick is firmly glued upon these
blocks or filling pieces; it may be of various woods and may be arranged to form any
desired pattern, such for instance as either of the two patterns shown on the right-
hand side of Fig. 1. The spaces over the pieces b and c between the blocks are filled
up with hard wood. The various parts are pieced together in the factory to form
flooring of any desired area, and may be thoroughly finished before being laid down,
so that the operation of laying down requires very little time, which is often of con-
siderable advantage, in such cases, for example, as when it is required to change or
relay a parquetry floor which is in constant use.
The flooring is fixed to the supporting beams by means of screws that pass through

page_text: the projecting lower portion of the outside transverse piece, before the adjacent surface
is laid down.
Screws are inserted at the bottom panel along the outside edge of the flooring.
When necessary, certain part of the parquetry over the pieces b and c instead of
being glued thereto in the factory may be glued after the flooring has been laid down
and has been fastened to the beams by screws passed through the pieces b and c at
those spots where such parts of the parquet have not been fixed.
As the boarding usually employed is dispensed with, the improved parquetry flooring
according to this invention can be made niuch more cheaply than the floorings
constructed as heretofore, and it is also more even. The improved flooring may if
desired be laid upon the usual boarding. In this case, the pieces b and c may be of
weaker scantling than when no boarding is already laid down.
Having now particularly described and ascertained the nature of the said
invention, and in what manner it is to be performed, I declare that what I claim is :—
1. Parquet flooring so constructed and arranged that it can be put together and
completely finished in the factory before laying down, substantially as described and
shown in the drawings.
2. The improved construction of parquet flooring with or without the floor boards
usually employed, substantially as described and shown in the annexed drawings, and
consisting of the continuous transverse pieces 6 into which are mortised the cross-
pieces c, the edges of the said pieces b and c being grooved to receive blocks covered
with parquetry, and the upper surfaces of the said pieces being also covered with
parquetry substantially as set forth.
3. In parquet flooring of the kind set forth in the preceding claim, fastening the
flooring to the supporting beams by means of screws which pass either through the
lower lips of the transverse, or through centre portions of the transverse pieces before
the parquet is applied to the latter substantially as described.
