1 Claim. (01'. 20-7) My invention relates to flooring of a type usually referred to as parquet flooring, and itemsists in certain details of construction-whereinfiooring of the type referred to is provided that 5 may be quickly and conveniently laid and will be comparatively inexpensive as well as'being of a, somewhat yielding and non-resonant character.

Referring to the accompanying drawing, which are made a part hereof and on which similar ref.- erence characters indicate similar parts, I

Figure 1 is a view showing one corner ofa floor laid with my improved flooring, the extreme corner being broken out to show the grainsand texture of the several layers comprisingthe full thickness of thefiooring.

Figure 2, a plan view showing one of the units or sections made up and ready for use,

Figure 3, a sectional view on the dotted line 3-3 in Figure 1,

Figure 4, a sectional View showing a modified form, v

Figure 5, another sectional view similar to a portion of Figure3, and

Figure 6, a view similar to Figure l but showing a difierent design. 7

In said drawing the portion marked 10 indicates the sub-floor or base on which the parquet flooring is laid and may be of wood, cement or any other appropriate material.

The flooring proper'is preferably made up in units or sections as shown in Figure 2, although the design may be of any form such as shown in saidfigure or in Figure 6 or any one of many which will readily suggest themselves to those skilled in the art. The units may be of such size 'as may be appropriate for the particular use to which they are to be put. 'Squares of two to three feet in dimensions have been found of convenientand appropriate size but other dimensions of course may be used when preferred.

The flooring consists of a core or filler sheet 11 composed of composition lumber made by saturating fibre with adhesive either after being formed into sheets or while said fibre is in loose condition and then formed into sheets of appropriate thickness. Said sheets are run through an equalizing machine to smooth them and make them of uniform thickness. To the opposite surfaces of said filler sheet are cemented binder sheets 12. To the top surface of the top binder sheet the parquet flooring strips are secured by cement or glue or any appropriate adhesive and to the lower binder sheet 12 is secured a complementary binder sheet 13 which in turn is secured to the sub-flooring by cement or where wooden sub-flooring is used the parquet units may be se- "blind nailing manner.

Border strips 14 formed in the same manner may be used or not as preferred. In the drawing I show such border strips but it will be understood that their use is a matter of choice and they constitute no part of the invention. Where border strips are used they are united to the adjoining parquet units by steel strips 15 inserted in grooves formed in the abutting edges of the strips and units. Like means is employed to unite .the abutting edges of the several parquet units throughout the width of the floor. These strips are inserted in grooves in the edges of the unit and extend across the joint between the units and serve not only to join the units but to close such joints against any possibility of the cement or other adhesive used exuding through the joint to the surface. 7 of fastening the parquet units together and to the The use of the filler 11 composed of fibrous substance formed into sheets of appropriate thickness and united by an adhesive compound lends to the floor a certain resiliency and also i sheet running parallel with the grain of the other;

while the sheet 13 on the under side of the filler is secured with its grain running at right angles with the grain of the sheets 12. By this means the tendency to buckle or warp on the part of the sheets 12 isbalanced by the action of the sheet 13 and the floor is thus preserved in a flat condition and the" buckling thereof guarded against. V

In Figure 4 the binder sheets 12 are omitted but otherwise the construction is the same as described for Figures 1 and 3.

Figure 5 shows a construction similar to that illustrated in Figure 3 and with the adjacent edges of the parquet units united by the inserted steel strip 15.

Having thus fully described my said invention, what I claim as new and desire to' secure by Letters Patent, is: r

A parquet flooring unit comprising a relatively thick core of a fibrous woody composition having a binder sheet cemented to its upper and lower surfaces, the flooring proper of the unit consist- This provides a very secure meansing of a plurality of parquet squares cemented to the upper of saidsheets, and a relatively heavy binder sheet cemented to the lower of said sheets, a groove in the edges of said core adapted to receive a metal securing strip, each unit adapted to be independently cemented to the sub-floor.
