This invention relates to an improved manufacture of parquet flooring whereby
the use of nails is dispensed with and whereby the strips or boards forming the
parquetry can be easily laid down and taken up.
For this purpose each edge of the ends of the boards which rest on the joists
is formed with a groove and each board is slid one after the other so that the said
grooves pass onto tongues of suitable material such as iron or onto the sides of
T shaped bars fixed in any suitable manner such as by means of screws or
otherwise on the joists or other wooden parts which receive the boards of the
parquetry in such a manner that the joints can be always made tight. and close
and that all or any of the boards can be rearranged as may be required no nail or
the like being employed in the construction.

page_text: I HECTOR AUGUSTE DUFRENÉ of N° 10 Rue de la Fidelité, Paris in the Republic
of France, Civil Engineer and Patent Agent do hereby declare the nature of my
invention for "AN IMPROVED MANUFACTURE OF PARQUET FLOORING" 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 an improved manufacture of parquet flooring whereby
the use of nails is dispensed with and whereby the strips or boards forming the
parquetry can be easily laid down and taken up.
For this purpose each edge of the ends of the boards which rest on the joists is
formed with a groove and each board is slid one after the other so that the said
grooves pass onto tongues of suitable material such as iron or onto the sides of
Tshaped bars fixed in any suitable manner such as by means of screws or
otherwise on the joists or other wooden parts which receive the boards of the
parquetry in such a manner that the joints can be always made tight and close
and that all or any of the boards can be re-arranged as may be required no nail or
the like being employed-in-the-construction.
The
In order to enable the invention to be fully understood I will describe the same
by reference to the accompanying drawing in which figures 15 and 16 represent
in section parts of parquet flooring illustrating the principle of my invention.
ends of the strips or boards A, resting on the joists B are formed at each end with
a groove and are slid one after the other so as to cause iron strips or tongues C,
figure 16 or the sides of T shaped bars of irou C figure 15 to pass into the said
grooves; the said strips or T shaped pieces are fixed in any suitable manner by
incans of screws or otherwise on the joists or other pieces of wood receiving the
strips or boards forming the parquet flooring so as to allow of the joints being
tightened up at any time, of changing or re-arranging all or any of the strips or
boards, no nail or the like being employed in the construction of the flooring.
In order to enable the strips or boards to be more easily taken apart they may
be provided with the said grooves only on one side alternately when they can be
removed successively one after the other. Below the flat strip or tongue I may
reduce the lower part of the strips or boards as shewn in figure 23 to allow the
screws or the vertical portion of the T iron to pass easily therein.
Figure 1, represents a plan of a piece of the parquet flooring having heading
joints and the ends of the strips or boards of which are represented in section in
figure 16. In one row or hay of strips or boards the grooved and rebated ends
alternate one with the other and each strip or board has a groove and a rebate.
Figure 2, represents a plan of a piece of herring bone parquetry of which
figure 15 represents a section; the ends of all the strips or boards are alike, the
disengaging of the strips or boards being effected by slightly rotating one of
their ends.
Figure 3, represents a plan of a piece of parquet flooring having regular and
straight joints the sections of which are shown in figures 17, 18 and 19; figure 17,
shews the underneath groove for allowing the tongue to be passed under the strip
or board and figures 18 and 19 shew in section the ends of the boards which
surround the boards shewn in figure 17, all the boards having grooves like that
shewn in figure 17. Figure 4, represents a plan of a frame of a piece of noveable
parquet flooring for heading joints or for herring bone parquetry; on this frame
are nailed the tongues for fixing the Boring. Figure 23, is a section shewing the

page_text: flooring at the sides of the frames situated near the wall and which serve to wedge
up the flooring so as to prevent movement in a horizontal direction.
Figure 5, represents a section of flooring which can be entirely taken to pieces
with hollow lath work, the joists not fixed and the flooring without nails according
to my invention. This parquetry allows of the floor being taken up and replaced
at will.
Figure C, represents in cross section an example of cheap flooring; between the
iron joists are placed deal cross pieces which receive the flooring on their upper
part the said flooring being fixed by means of the iron tongue and under the laths
which receive the plaster forming the ceiling.
Figures 7, 8 and 9 represent in cross section various methods of fixing the
parquet flooring to the joists; the double and single T irons are screwed onto
the joists.
Figure 10, represents in cross section the metho1 of fixing by moins of strips or
tongues; figure 11 shews in cross section the arrangement which may be employed
in powder inills or magazines in which arrangement no iron is used; the boards
are formed on the joist the latter being sealed with pitch.
Figure 12, a section shewing how in an old parquet flooring a worn out part
can be replaced. After having taken up the worn part and cut the edges quite
straight the joist is slid underneath to receive on one side the old parquet flooring
and on the other side my system. Figure 13, represents a section of a joist for
placing under walls or partitions so that if the latter should be removed there is
no break of continuity in the flooring which is perfectly level.
Figure 14, represents in section a board with a rabbetted edge which will allow
of its being replaced when it is much worn when it is desired to again tighten up
the parquet joints in consequence of the drying of the wood.
Figures 17, 18 and 19 represent sections of boards of hending jointed or herring
bone parquetry with regular joints as hereinbefore referred to.
Figure 20, represents in section a board in which the groove and the ordinary
hoop iron tongues are replaced by a small tongue this arrangement gives a much
stronger check above and consequently greater solidity and longer wear.
Figure 21, shews in cross section an example of cheap parquet flooring; with
rough wood a groove can be made through a portion of the length of the board and
a small piece of flat strip or tongue be inserted therein, or a hole may simply be
bored therein to receive a pin or bolt.
Figure 22, shews in cross section the form of joists and boards for parquet
flooring on asphalt to afford greater adherence. The rib made therein gives
solidity to the boards one with the other and renders it almost impossible for them
to rise out of place.
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
1 claim is
The arrangement of parquet flooring above described in which the strips or
boards are provided at the end with suitable grooves for receiving flat strips or
tongues of iron or wood which allows of fixing the strips or boards on the joists
without the aid of nails or screws.
