STORM SOUND AND HEAT INSULATED FLOORING Filed May 2, 1931 2 Sheets-Sheet 2 Patented ,lune 28, 1932 RAYMOND W. STORM, @F PEL MANOR, NEW YORK -sonivn .aan naar rnsuaarnn anonime' .application ler'l may 2, 193i. Serial No. 534,631.

The invention relates to ooring and has as an object the provisionof a Hooring that will be quiet in use both as regards the apartment wherein the material is laid and an apartment therebelow.

llt is a further object of the invention to provide a floor material'that may be prepared at the factory and very rapidly laid.

lt is a further object to provide a construcll@ tion of Hoor element that lends itself readily to factory production and which makes possible the utilization of short lengths of material.

Further objects of the invention will apw pear from theV following description when read in connection with the accompanying drawings showing illustrative embodiments of the invention, and wherein:

Fig. 1 is a bottom plan view of an element provided by the invention which may be assembled with other similar elements to form a door;

Fig. 2 is a section on line 2 2 of Fig. 1;

Fig. 3 is a vertical transverse section of three assembled elements such as shown in Figs. 1 and 2;

- Fig. d is a bottom plan view of a modified form of element;

Fig. 5 is a section on line 5-5 of Fig.

Fig. 6 is a transverse section of a further modification g Fig. 7 is a bottom plan view of a still further modification; and l Fig. 8 is a detail section on line 8-8 of Fig. 7 to an enlarged scale. y

As shown in Figs. 1 to V:3 inclusive, the door is formed of a wearing surface layer element 10 desirably formed of wooden elements each having a tongue 11 at one edge and being grooved as at 12 upon the ,remaining three edges. The lower surface of the wearing layer is shown as rabbeted at the back as indicated at 13 and a resilient bearing element 14 is shown as provided with an upstanding rib 15 to fit the rabbet 13 in the wearing layer. The surface of the element 14 is coated with glue before being applied to 'the wearing layer 10 and the rib and rabbet joint between the elements serves to guide the two parts into proper relation when assembled.

As is usual with flooring the portion below the t0n ue 11 and also below the grooves 12 sets bac of the plane of the portion 16 above the tongue and grooves to ensure that the joint at the surface of the flooring shall be tight.

'llo assist in securing the element 1a to the element 10, there are shown driven fastening elements 17 which, in addition to their securing function, have another function to be en plained below.

rl`he\bottoin of the assembled elements as 18 and the edges of the same as 19, as well as the edges of the wearing layer 10, are coated with an integral layer of cementitious or bituminous material, 'as asphalt. The said layer is desirably applied at the. time of laying the floor by dipping the elements into a pan of hot material and immediately placing the same upon the suboor, thereby cementing' the assembled elements to the subdoor as well as increasing the strength of the ele ments in a manner also to be explained hereinafter.

ln the forni of the invention of Figs.` d and 5 the bearing elements are shown in the form of frusto-conical or cylindrical members 2() seated in correspondingly shaped recesses 21 in the non-wearing surface of the wearing layer, and the lower exposed surface of the wearing layer 10 of this form of the invention, the vertical surfaces of the elements 20, and the bottom surfaces thereof are also coated with cementitious material, which r material is carried up around the edges of the wearing surface layer elements as at 22.

lln the form of the invention of Fig. 6, the wearing surface layer 10 is formed as in Figs. 1 to 3 inclusive.' but the bearing material 23 is shown as rectangular in cross-section and El@ does not extend below the portions 24, 25, of the wearing surface element. ln this form of the inventionalso driven elements 17 are indicated and the cementitious layer 18 is also applied about the entire lower surfaces of the assembled flooring element.

ln the. form of the invention of Figs. 7 and 8the rabbets in the non-wearing surface of "the elements 10 are shown as transverse, two

rabbets being indicated in each of the sur- -dll v much more face elements, although ot course it is obvious l that more than two may be used. ln this Vilorm of the invention, there is indicated a plurality of surface elements 10 held in assembly by the bearing material 26 seated in the transverse rabbets 27 and extending continuously across the assembled elements. lit is obvious that the elements 26 in this form of the invention may extend across one only of the elements l0 and that the elements 10 may then be separately assembled upon the door in the same manner as indicated in Fig. 3. ln this form of the invention also driven elements 17 are indicated.

'lhe bearing material lll, 20, 23, and 26 may be formed of a wide range ot materials as, for instance, cellulose nbre wallboard, rubber, balsa wood, linoleum, cork either natural or molded cork composition, or any resilient spongy composition. ln the form of the invention of Figs. 1-3 and (#8 inclusive, it is at present preferred to use cellulose bre wallboard material, as this material is readily available and very suitable for the purpose.

The form of the invention of Figs. 4L and 5 lends itself admirabl to the use of ordinary corh such as used tor bottle Stoppers.

A. defect of former lloors of the nature of the present invention which have been laid with cellulose ibre wallboard material has been that the wallboard adheres perfectly to the subdoor when laid in bitumlnous material and the surface of the wallboard also adheres to the wearing surface layer by being nous material as indicated at 19, Fig. 3, which greatly strengthens the bearing surface layer made up of the assembled elements from such splitting due to the fact that -many vertical ribs 19ers thus provided throughout the entire oor area, and, second, by the presence of the fastening elements 17 Another defect in former floors of this character has been that the entire floor surface of a room acts as a diaphragm `vibrating with resonance vto transmit the sound of any" blow thereon, as produced by a footfall. The presence of the driven elements 17 acts as an effectual damper to such vibration and {iooring of this character which has been laid and tested in service discloses the fact that because of these driven fastening elements, the completed floor is quiet than doors formerly provided. a

When wood is used, the flooring utilizes maarre short lengths of the material and is therefore very economical to produce.

The presence of the recesses in the nonwearing surface of the wearin layer engaging projecting portions of theearing maten rial has the function in use of anchoring the surface layer to the bearing layer in such manner that lateral displacement of the surtace layer under expansion and contraction carries with it the adjoining portion of the bearing layer thus greatly increasing the strength of the flooring in service.

liti

The cementitious layer 18 has the function not only of causing adherence of the dooring to the subi'ioor thereby doing away with the necessity of nailing the ooring down but also prevents access of moisture to the bearing layer which would rapidly cause the same to deteriorate.

rl`he consequent avoidance of the necessity of nailing the flooring down also greatlyV improves the sound insulation of the door, as in lformer insulated floors Where the door was nailed to the subfloor through the bearing layer each nail acted as a rigid column to' transmit sound vibrations to the subdoor and thus to the apartment below and the sound insulation of the bearing layer was in these former constructions very largely lost because of this fact.

ln the foregoing description the main emphasis has been placed upon the sound deadening function of the invention. ln addition to this function, the nature of the materials used and the construction disclosed secure valuable ed'ects in heat insulation.

The word cementitious in the appended claims is used as a generic term including bituminous material as asphalt which is the material at present preferred.

Minor changes may be made in the physical embodiments of the invention within the scope. of the appended claims without departing from the spirit thereof.
