2 Claims. (01. 154-49) Our invention relates to a composition intend-' ed tor-use as a lining to the back of rugs, carpets and the like, to render them non-slipping on polished floors, to cause them to lie flat .on'

the floor without wrinkling and to impart a greater body and elasticity to them, with the result that the wearing quality of the ms is improved. n

It is known in the art to apply a coating to the 6 back oi rugs which renders them non-slipping and while our composition imparts this quality to the rugs, the main object is to increase thedurability of the rugs and impart to rugs of medium grade the appearance and ie'el.oi expensive rugs having a heavy and closely woven nan Our invention consists in the composition of matter hereinafter described and pointed out in the claims.

The following is a a preferred -example of the composition: 1 c

, I Pounds Flour, preferably wheat flour i Magnesium chloride solution of 36 B. 25 strength 3 Finely powdered silica 2 '35 cess of wood flour or sawdust is removed therefrom and a coating otsheliac is applied.-

In place of the ground silica other fillers, such as clay, sawdust, wood flour, may be used and V the proportionmay be' increased or decreased 40 as desired, or thefllleri may be omitted a1together. The elasticity of the coating is decreased "as, the amount of filler is increased. We have iound no substitute for magnesium chloride which, as well known, is a hygroscopic substance.

' 4s Glycerine and calcium chloride have been tested qualities or the rug.

but we flnd that the resulting composition is unsatisfactory and that magnesium chloride is essential. It is necessary to apply wood flour or sawdust to the coating while still wet., It the same were omitted and the coating allowed to 1 dry without the application of wood flour or sawdust the coating would in the course of time adhere to the floor. However, in place of applying the wood flour or sawdust to the plastic coating a sheet of burlap may be applied and pressed up into it-so that it will firmly adhere thereto. The burlap will then prevent the sticking of the mg to the floor and also impart thereto a non-slip- Pi s quality. i I

The proportions of the ingredients stated are is those preferred by us although they may be varied, as will be understood by those in the art, and still give good results.

The average thickness of the coating applied to the back of the rug and the like is about onesixteenth -inch but the thickness will vary ac-- cording to the texture of the rug or carpet. In place of burlap other similar material, such as cheesecloth or coarse absorbent paper, may be used in forming a backing.

As stated above, the silica filler may be omitted. However, I prefer to use the same, especial 1y where in addition to the non-slip qualities of the rug additional weight and body thereof are idesired. Furthermore, the use of a heavy filler so such as silica will improve the non-wrinkling We claim:

1. A rug having a lining applied to the back consisting of a composition made oi. wheat flour,

' one pound; magnesium chloride 36 B., three consisting of a composition made of wheat flour,

one pound; magnesium chloride36 36., three pounds; and a sheet of burlap imbedded in the suriace of the lining.
