I, JOSEF FRANCIS EBNER of Clerkenwell Road in the County of Middlesex
Parquet Manufacturer do bereby doclare the nature of this invention to be as
follows:-
My Invention relates to a simple and effective method of laying and securing
parquet and other floorings.
In the Specification of Letters Patent granted to me and dated 10th June 1885
No. 7082 a method was described of securing parquet flooring to stone concrete wood
metal or other surfaces by means of undercut channels undercut recesses or oblique
holes formed in the underside of the flooring and in the upper surface of the bed
upon which the flooring is laid into which under cut recesses the asphalte or other
composition employed to unite the two surfaces together entered so as to firmly
secure the parquet or other flooring to the bed or foundation.
Now 1 have found in practice that it is very advantageous to form the undercut
channels or recesses by inserting strips of metal the section of which is of dovetail
shape such channels being embedded in the cement concrete or other bed whilst in a
plastic state thus forming a metal lining or protection to such undercut channels or
recesses.
The under surface of the parquet or other flooring or the blocks forming the same
are also formed with undercut recesses so that when the two surfaces are combined
the intervening cement or composition enters into the recesses above and below and
firmly secures them together.
The metal channels may be formed in one two or more parts if desired:
A further part of my present improvements is the method of laying or forming
common wood block floorings in the same manner as I lay or form parquet floorings
described in my before mentioned specification.

page_text: I JOSEF FRANCIS EBNER of 51 Clerkenwell Road in the County of Middlesex
Parquet Manufacturer 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 following statement:—
My invention relates to a simple and effective method of laying and securing
parquet and other floorings.
In the specification of English Letters Patent granted to me and dated 10th Juno
1885 No. 7082 a method was described of securing parquet flooring to stone,
concrete, wood, metal or other surfaces by means of undercut channels undercut
recesses or oblique holes formed in the underside of the flooring and in the upper
surface of the bed upon which the flooring is laid into which undercut recesses the
asphalte or other composition employed to unite the two surfaces together entered so
as to firmly secure the parquet or other flooring directly to the bed or substructure.
Now I have found in practice that it is very advantageous to form these undercut
channels or recesses by inserting in the substructure strips of metal the transverse
section of which is of a dove tail shape such channels being embedded in the cement
concrete or other bed forming the substructure whilst in a plastic state thus affording
a ready and effective means of forming such undercut or dovetailed channels or
recesses and also forming a metal lining or protection thereto.
And in order that this part of my present invention may be the more easily under-
stood and readily carried into practice I will now proceed to further describe the
same with reference to the accompanying drawings Figure 1 of which shows vertical
sectional view of flooring laid in accordance with my improvements Figure 2 shows
a transverse section and Figure 3 a plan of the dovetailed metal lining for
embedding or inserting in the plastice bed or substructure whilst in a plastic
state.
The under surface of the parquet or other flooring or the blocks forming. the
same are also formed with undercut recesses so that when the two surfaces are
combined the intervening mastic (asphalte or other composition) enters into
the recesses above and below and firmly secures them together.
Referring to Figure 1 a is the metal lining (shown on an enlarged scale in
Figures 2 and 3) permanently embedded or inserted into the cement concrete or other
bed or substructure b whilst in a plastic state.
Asphalte or other composition c unites the parquet or other flooring d directly to
the bed or foundation by entering into the channels a and the undercut
channels or recesses in the underside of the wood blocks thus when set firmly uniting
all parts together.
The metal channels Figure 2 may be formed in one two or more parts if desired.
A further part of my present improvements consists in laying or forming common
deal or other wood block floorings in the same manner as I lay or form parquet
floorings described in my before mentioned specification.

page_text: 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 :-
1. In the laying or forming of parquet and other wood block floorings the use
and application of dovetail shaped metal channels such as a substantially in the
manner and for the purposes hereinbefore described and represented in the
accompanying drawings.
2. The improved method of laying or forming and securing parquet and other
floorings substantially as hereinbefore described and represented in the accompanying
drawings.
3. The improved method of laying or forming common deal or other wood block
floorings substantially as hereinbefore set forth.
