do hereby declare the nature of this invention to be as follows;
-
In order to deaden the sound in parquetry floorings and also to absorb any
moisture arising from beneath, the ceiling or flooring beneath has been
provided with a felt cover or the like as an under-lay and parquetry
was merely laid on
the said felt cover. As these felt or the like
under-lays however do not allow it to be seen where the beams of the
floor pass under the flooring boards or the supports of the ceiling, it is of course
very difficult to firmly nail the parquetry blocks on the said beams and the latter
operation is caused to be inconvenient, time-consuming and yet unreliable.
This invention has for its object improved parquetry blocks and strips which
act as sound deadeners, absorb moisture, and yet do not render it difficult to find
the flooring beams and nail the parquetry on the latter.
For this purpose a cork or peat sheet is fixed on the under side of the par-
quetry block or strip which sheet in the case of blocks or strips in which the
tongue and groove lie on the under surface is not extended to the edge of the
groove or the tongue but to the edge of the block so that on the blocks being
placed together the tongues lying between the same will rest on the cork or peat
sheet.
These parquetry blocks and strips may be removed as rapidly and easily as
the ordinary strips, and the cork or peat sheets form, when the floor is finished,
as completely closed a layer as in the flooring mentioned at the commencement
of this specification in which large sheets of felt are employed as an under-lay
for the parquetry blocks. Further, owing to the fact that in this improved par-
quetry a vegetable material is employed as a sound deadening layer instead of
an animal one, such for instance as felt, it affords a greater security against the
accumulation and formation of infectious matter, than a floor having a felt under-
lay.
A further advantage consists in that the person laying the parquet flooring has
no such work as cutting out and fitting of the sound deadening covering to carry

the floors hitherto employed.

strasse, Zürich, in the Republic of Switzerland, Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester,
both in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer,
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 follow-
ing statement:-
In order to deaden the sound in parquetry floorings and also to absorb any
moisture arising from beneath, the ceiling or flooring beneath has been
provided with a felt
cover or the like as an under-lay and parquetry
was merely laid onl the said felt cover. As these felt or the like
under-lays however do not allow it to be seen where the beams of the
floor pass under the flooring boards or the supports of the ceiling, it is of course
very difficult to firmly nail the parquetry blocks on the said beams and the latter
operation is caused to be inconvenient, time-consuming and yet unreliable.
This invention has for its object improved parquetry blocks and strips which
act as sound deadeners, absorb moisture, and yet do not render it difficult to find
the flooring beams and nail the parquetry on the latter.
In the accompanying drawings, Figure 1 is a plan view of a piece of parquetry
floor; whilst
Figures 2 to 6 show various sectional details of the attachment of the strips.
For the purposes of this invention a cork or peat sheet bis fixed on the under
side of the parquetry block or strip a (Figure 4) which sheet in the case of
blocks or strips in which the tongue and groove lie on the under surface
(Figures 2, 3, 5 and 6) is not extended to the edge of the groove or the tongue c
but to the edge of the block a so that on the blocks being placed together, the
tongues lying between the same will rest on the cork or peat sheet, (Figure 2).
These parquetry blocks and strips may be removed as rapidly and easily as the
ordinary strips, and the cork or peat sheets form, when the floor is finished, as com-
pletely closed a layer as in the flooring mentioned at the commencement of this
specification in which large sheets of felt are employed as an under-lay for the
parquetry blocks. Further, owing to the fact that in this improved parquetry
a vegetable material is employed as a sound deadening layer instead of an animal
one, such for instance as felt it affords a greater security against the accumulation
and formation of infectious matter, than a floor having a felt under-lay.
A further advantage consists in that the person laying the parquet flooring has
no such work as cutting out and fitting of the sound deadening covering to carry
out and consequently the laying of the parquetry can proceed more rapidly than in
the floors hitherto employed.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is:-
Parquetry blocks and strips provided with sound deadening arrangement,
characterised by a sheet of cork or peat being fixed on the underside of each block
or strip so as to meet at the edges, substantially as described.
