J. J. KOCHER SOUND DEADENING DEVICE Filed NOV. 12, 1928 MQW ymw g@ Jam 2s, 193o mi@ 7//1 Wm/vf a. #d W Patented Jan. 28, 1930 JACQUES JEAN ROCHER, GF CHICAGO, ILLINOIS SOUND-DEADENING DEVICE Application led November 12. 1928. Serial No. 318,789.

for use in floor construction which may be conveniently and completel manufactured to avoid assembly on the jo toprovide attaching means which ma be conveniently mounted on a stri of vibration insulating material such as elt, and permanently secured thereto before installation in that position in which it is ultimately used in a floor construction, and to provide integral clips on a device of the class described formed to allow insertion through slits in a felt member and to prevent separation of the latter from the device.

Another object of my invention is to provide means .for confining a sound deadening member in a fixed location between the superimposed layers .of flooring in such a manner as to minimize the amount of rigid connection between said layers.

In the accompanying4 drawing I have shown an embodiment of my invention in which Fig. 1 is a fragmentaryperspective of a completed sound deadening element.

Flg. 2 is a transverse section taken .on the line 2 2 of Fig. 1.

Fig. 3 is a section of a floor construction embodying my invention.

In general, my invention embodies an improved sound vibration insulating means comprising a strip of felt having improved stra s permanently mounted thereon, forinstal ation between a finish layer and a furring strip of a Hoor. The attaching member comprises a strap having opposite feet portions substantially in the same plane, and a top section in a spaced, substantially parallel plane. V The feet and top sections are connected by inclined side portions. Clips integral at one end with. the top section are cut out of the latter and bent downwardly substantiall perpendicular to the top section. The ree end portions of the cli s are formed to provide a flange which is su stantially arallel to the top section.

In t e form shown in the drawings, sound resisting layers 1, preferably comprising felt, are located between a roughl layer of the floor 2 and a furring strip 3 supported thereon. The finish lor top layer 4 of the floor is supported in turn by the furring strip 3 as shown in Fig. 3.

My improved sound deadening means comprising a felt strip 5, is located between the top layer 4 of the floor and the furring strip 3 and is firmly clamped on the top of the furring strip by a strap 6. The strap 6 is provided with feet ortions 7 which engage the upper surface o the felt member 1, and thus avoid a direct rigid connection between the upper and lower layers of the floor.

During the construction of a floor such as is shown in the drawings, it is desirable to have all the elements required, arrive on the scene of construction in as complete a condition as possible in order that time and labor may b e saved on the job. For this reason it has been found practical to permanently and securely attach the straps 6 to the felt strip with a flange 10 which is substantiall parallel to the top sections 9, as shown in ig. 2. The straps may be conveniently secured to the felt strip 5 by inserting the clips 7 through slits in the felt member so as to engage the flange 10 against the lower surface of the felt member as viewed in the drawing. Any desired number of straps may be simllarly mounted on the felt member and when the latter is' positioned over a furring strip, the straps together with the felt member ma be held permanently in place by driving nai s through a ertures in the feet of the strap and through the felt layer or layers 1 into the bottom layer of the oor 2.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that details of the construction shown may be altered or omitted without departin from the spirit of this invention as define by the following n claims.

I claim:

1. A ioor comprising a rough underfloor, spaced furring strips thereon, a top finishfioor and elongated sound insulatingsaddles interposed between said finish-Hoor and strips, said saddles having mutually-spaced bowed perforate-footed downholding straps attached thereto for anchoring tensionally to the underfloor.

2. In a floor construction comprising a rough layer, a finish layer, and furring strips therebetween, a sound resisting element between said rough layer and said fui-ring strips, and vibration insulating means between said finish layer and said furring strips, said insulating means having straps permanently fixed thereto independently of the Hoor construction, and feet on said straps for tensionally securing the same, together with said sound resisting element to the rough layer of the flooring so as to embed the top part of said strap in said insulating material.
