The present invention relates, generically, to composite wooden surfaces, such as wall panelling, flooring (strip, parquet, etc.) andthe like. More particularly, this invention type of composite wooden surface which is adapted to be laid on underfloorings or back ings of concrete and similar material.

It is a common; experience in the flooring tradeto findthat in strip flooring laid upon 7 concrete underflooring there is a marked tend ency, for the strips to separate from each other and to leave relativelylarge and unsightly crevices therebetween. This has been partially overcome by the use of an intermediate layer of :wood between the'concrete backing member and the surface flooring, the latter being nailed or otherwise "securedto theintermediate layer. The use'of the intermedi- 1 The primary object of the present nvention to provideafastener for the strips or component members '(such as unitsof-paracter above describedwhich maybeeasilyand? n p n ve f m in. dies ut stri' a tal' "as of -a;single f; f

In the said'drawinggfl r Fig. 1- is a cross-sectional viewthrough a portion of flooring and" concrete 5 sub-floor ing, embodying- ;the present inventiongfandj showing one stripiof flooring already laid and, a second strip in process ofbeing laid; f Fig. 2 is a view similar to Fig. 1, showing both strips of flooring in laid position;

e athei e 7 Side,

". a v I of vertical pontions 18 The ye gtieal portions 18 are adapted to be received in the space left between shortened tongues 14 of adjacent strips of flooring, as

- is clearly shown in Figs. 1 and 2.

Base portions 17 are formed with longitudinally extending beads 19 intermediate the sides thereof and ate. point thereon beyond the corresponding tongue 16. When these beads 19. are ultimately flattened out, as and for the purpose hereinafter described, the

base portions 17 aresubstantially coextensive with and adapted to be received in the rabbeted grooves 13. The base portions 17 extend only from one side of the vertical members 18, and with the corresponding tongues 16 form sockets adapted to receive the tongues 14 of adjacent flooring strips. The tongues 16, vertical portions 18 and bases 17 of the fasteners 11 are continuous and longitudinally coextensive with each other.

The fasteners 11 may be cut into conven ient lengths and cooperate with flooring strips, as shown, to provide a firm support therefor along the entire length thereof.

' At the crests thereof, beads or raised portions 19 are formed with a plurality of spaced nail-receiving holes or openings 20. Substantially midway between these openings 20,

I thebeads may be and preferably 'are provided with suitably shaped slits or cut-outs In; describing the method of laying a floor according to the present invention, particular reference will be had to Figsil and 2 of underflooring 15 is preferably first coated with-a layer of mastic or similar material.

-As.shown' in Fig. 1, strip 10a has'already.

beenlaidand its fastener 11a secured in place on the underflooring by means of nails or other fastening elements 22. This leaves one tonguelfi and the flattened base 17 exposed, the other tongue 16 being received in a groove 12 of the'strip 10a. A second strip of flooring 10b is then put in place, a groove 12 thereof receiving the said exposed tongue 16,and a rabbet 13 receiving the flattened base 17. It has been found by experience that the 'several strips cannot ordinarily be laidso;that

they will contact along the entire adjacent sides thereof, but that there is always a slight space therebetween, as shown at 23iuF-i'g. 1. 'The tongue 16 of a second fastener 11b is then inserted into the exposedgroo've. vI2 of the strip 106 with base portion 17 oflthe fastener 11?) extending outwardly. Nails 22 said base portion intermediate'the sid are then driven into the concrete sub-flooring 15 through openings in the beads 19. This flattens the bead out and increases the effective width of the base 17. To accommodate this increase in width, the strip 10b is forced over to the left (in Fig. 1) into intimate contact with the strip 10a, thus eliminating the opening or crevice 23. Since the nails 22 penetrate into the concrete before the flattening of the beads begins, they, of course, do not give, and separation of adjacent strips to form spaces therebetween is positively prevented. This process is continued with additional strips and fasteners until the entire floor is laid. The slits or cut-outs 21 are adapted to receive superfluous mastic from the surface of the mastic-covered sub-flooring, thus aiding in securely holding the fasteners down on the latter.

It will be thus seen that a simple and efficient fastener has been provided for use with flooring designed to be laid upon concrete under-floors. It is obvious that the improved fastener may be equally well used with properly milled units of parquetry in the laying of parquet flooring, and also in the laying of the panels of composite wall surfaces.

In accordance with the patent statutes I have described the principles and particu ar have illustrated and described a particular formation, I desire to have it understood that the same is only illustrative of a means of carrying out my invention in one form and that obvious changes may be made by anyone skilled in the art within the scope of the following claims without departing! from the spirit of my invention.

I claim: a

1. In a fastener for flooring and the like a base portion extending laterally from the body of the fastener, and a nail recei raised portion extending longitudinall o y t ereof, said raised portion being adapted to be flattened when nails are driven therethrough into the flooring or the like.

2. A device of the class described comprising a vertical body portion, a pair 'of tongues extending laterally in opposite directlons from the top of said body portion, a base portion extending laterally from said body portion at the bottom thereof, saidbasef portion having a bead extending longitudinally thereof and adapted tobe flattened.

3. A fastener for flooring and: the like adapted to bemade'from a single stripoffsheet metal comprising a vertical member; a pair v mi r of two-ply tongues at the top of said-vertical member, abase'portion at the botton'i; of said vertical member, a raised bead extending longitudinally of"*said base portion, said; head having a plurality of nail-receiving openings at the crest; thereof. 4. In combination with a strip of flooring disposed upon a sub-flooring, a fastener for said strip of flooring, means to anchor said fastener to said sub-flooring, and raised means on said fastener adapted when flattened to force said strip into intimate contact with the next adjacent strip of flooring.

1 5. The method of laying flooring upon concrete sub-flooring comprising disposing a fastener adjacent a strip of flooring, anchoring said fastener to said sub-flooring, and then increasing the eflective width of said fastener,

whereby said strip of flooring is forced into I intimate contact with the next adjacent strip of flooring.

6. A fastening'device comprising a base portion, a vertical portion attached thereto, 7 2 a plurality of tongues extending laterally from said vertical portion, said base portion and vertical portion being longitudinally coextensive and continuous, and raised means on said base portion adapted, when flattened, to increase the effective width of said base portion.
