Year: 1884

I GEORGE FREDERICK REDFERN of The General Patent Office 4 South Street,
Finsbury in the county of Middlesex Patent Agent, do hereby declare the nature
of the said invention for "AN IMPROVED MANUFACTURE OF PARQUET FLOORING
a communication to me from abroad by Monsieur Felix Emile Guerin of 24 Rue
Angier, Paris in the Republic of France, Parquetry Manufacturer to be as
follows:
This invention relates to further improvements in the parquet flooring for which
Letters Patent were applied for by Hector Augusto Dufrené on the fifteenth day of
April 1884 N° 6388 the present improvements having for object to render the
parquetry strips or boards independent of one another and to avoid the necessity of
fixing them on the joists or beams.
For this purpose the strips or boards are formed with a groove into which takes
an iron tongue perforated with holes and fixed to the joists by means of screws; in
place of tongues I can employ T, or double T, irons this arrangement may be employed
either for ordinary parquetry or for herring bone parquetry; instead of employing
iron tongues I can employ wood. They may also be on one side let into pieces of
wood which extend to the level of the parquetry principally at those parts which
come next the walls or partitions.
A modification of the arrangement consists in employing strips or boards grooved
on one side and provided on the other side with an iron pin or dowel for fixing
them to the following boards.
The improvements are applicable to thick floorings constructed of blocks solidly
fixed together by means of pins or tongues taking into the adjacent blocks; the
blocks can slide in the upper part of the T irons which support the flooring.

I GEORGE FREDERICK REDFERN of The General Patent Office 4 South Street,
Finsbury, in the county of Middlesex Patent Agent do hereby declare the nature
of the said invention for "AN IMPROVED MANUFACTURE OF PARQUET FLOORING
a communication to me from abroad by Monsieur Felix Emile Guérin of 24 Rue
Angier, Paris in the Republic of France, Parquetry Manufacturer 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 further improvements in the parquet flooring for which
Letters Patent were granted to Hector Auguste Dufrené dated the fifteenth day of
April 1884 No 6,388 the present improvements having for object to render the
parquetry strips or boards independent of one another and to avoid the necessity
of fixing them directly on the joists or beams as is the case in ordinary nailed
parquet flooring.
For this purpose the strips or boards are formed with a groove into which takes
an iron tongue perforated with holes and fixed to the joists by means of screws or
their equivalents; in place of tongues I can employ T or double T irons; this
arrangement may be employed either for ordinary parquetry or for herring bone
parquetry; instead of employing iron tongues I can employ wood. They may also
be on one side let into pieces of wood which extend to the level of the parquetry
principally at those parts which come next the walls or partitions.
A modification of the arrangement consists in employing strips or boards grooved
on one side and provided on the other side with an iron pin or dowel for fixing
them to the following boards.
The improvements are applicable to thick floorings constructed of blocks solidly
fixed together by means of pins er tongues taking into the adjacent blocks; the
blocks can slide in the upper part of the T irons which support the flooring.
In order to enable the invention to be fully understood I will describe the same
by reference to the various figures of the accompanying drawing.
Figures 7, 8, 9 and 10 shew sections of pieces of parquet flooring having different
forms of iron tongues or T, or double T irons which may be employed-This
arrangement can be applied to the parquetry known as herring bone parquetry,
parquet flooring having regular and straight joints, and parquet flooring having
heading joints; figures 15, 16 and 17, are sections of pieces of the parquet flooring
shewing different ways in which the tongues can be employed.
In powder magazines and powder mills where iron cannot be employed I use the
joists shewn in cross section at figure 11.
In adapting the improvements to renewing the worn part of the flooring of a
passage so as to leave the old wood at each side of the passago I make use of the
joists shewn in cross section at figure 12; on the tongue side of the joist is placed
my improved arrangement and at the other side is fixed the old parquet flooring.
Figure 13 shews in cross section a joist to be used under removeable partitions ;
in the event of the partition being removed the parquet flooring will be level and
no joining up will be required.
Figure 14 represents a rebated bordering placed along the wall and screwed for
receiving the nails fixing the carpet and which bordering when much worn by the
nails may be easily and quickly replaced.
Figure 18 is a section of a board in which the groove and the tongue cut
plankwise are replaced by a groove into which takes a strip of hoop iron, this

page_text: arrangement allows of having a stronger portion above the groove which gives
greater solidity and greater durability.
Figure 19 shews in cross section an example of cheap parquet flooring which is
grooved at the end and on its side at about the centre it is provided with an iron
dowel or pin; this kind of parquet flooring made with rough wood is very
economical.
Figure 21 shews in cross section a form of parquet flooring or joist on asphalte
or mineral pitch; the grooves made at the lower part receive the asphalte and
firmly fix the joint and prevent it from rising.
Figure 4 represents a plan of a framework for and figure 20 a cross section of an
arrangement of portable parquet flooring for gardens, courts, conservatories, ball
rooms &
Figure 6 is a cross section shewing deal cross pieces provided with holes to allow
of the admission of air, the parquet flooring is fixed above by tongues or hoop iron
running across the grain to allow of it being taken to pieces-The underside of the
cross pieces is provided with laths and iron wires at the iron joists to prevent
chinks.
Figure 22 shews in cross section a flooring formed of blocks of wood or other
suitable material dispensing with the strips of parquetry, plastering and ceilings
but when required a coating of plaster, cement, asphalte, or other material may be
added on one or both faces so that the wood may be stained or painted; the
blocks are shewn rabbeted on the four sides and can be connected either by iron
tie bolts in the joists or by tongues, rods, or pins of wood, iron or other suitable
material.
Figure 24 shews a similar arrangement of flooring but having a block in the
form of a key stone and having pins (or not) in one or both directions.
Figure 25 represents in cross section a flooring with a strip cut plankwise and
more or less thick or wide with supporting pieces resting on the lower projections
or flanges of the iron joists to prevent the upper part from giving way through
shocks or wear.
Figures 26 and 27 are cross sections in which the blocks are square and are
provided either with rods, pins or strips in one or both directions.
Figures 28 and 29 shew in cross section the application of the various arrange-
ments hereinbefore described to single T joists.
Figure 30 is a cross section and figure 32 a plan shewing the blocks chamfered
off at each upper edge. This arrangement is specially suitable for carriage
entrances and court yards for preventing horses from slipping and can be applied
to all the arrangements above described.
Figure 31, is a plan showing the blocks forming the flooring level or nearly level
with the upper flanges or projections of the joists leaving the joists exposed to
view as shewn in section at figures, 22, 24 and 27.
Figures 25, 26 and 30 shew the arrangement employed to conceal the joists from
view; figure 29 shews this arrangement applied to a single T joist.
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
The various arrangements herein before described and shewn in the various
figures of the accompanying drawing, allowing of employing parquet flooring
without nails substantially as herein before described.
