Be it known that. I, FRANCIS W. TULLY, aA citizen of the United States, and resident of Brookline, in lthe county of Norfolk and State of Massachusetts, have invented new anduse'ful Improvements in Rugs, Mats, yor other Coverings and Methods of Making the tion. This invention relates to rugs, mats, carpets and other coverings, one object of my invention being to prevent slippage of such an article whenplaced on a slippery surface such as a polished floor, as well as topro-v vide means whereby the rugs, etc., are made tolie fiat upon the floor, and to'resist their tendency to wrinkle or curl.

Y Such coverings in use, but especially mats andrugs intended for floor-coverings, are 2Q renderedV of less than `their full utility when fastened to the floor or other surface, and are the frequent cause of accidents to 'per-y sons stepping on them when not fastened. i Various methods and devices have heretofore been resorted to for: preventing yslippage, but all such devices of which lI` am failure of any general use of such devices. Metaldevices attached to thel rug for engage'- ment with the floor are injurious to the floor when not intended for a definite place on the limit the usefulness Aof the rug or mat except in that place, and prevent random placing ,of

the rug so as to avoid .destructive wear at en marts only thereof. The in etal fastening itself,`of whatever form, makes a projection under the rug `above which destructive'wear takes place rapidly. Rubber. patches-, gr 40 patches of rubber cl'oth, sometimes fastened on theunder surface of the rug,`while free permitting the ru which the surface of the rug wears off. in use, besides being ineffective unless so large and frequent'as to be too expensive for ordinary use. I attribute the lack of' effect of rubber-cloth and the like to the insufficiently yielding and insufficiently sticky surface of such materials, which Will-not hold against a sharp lateral strain unless subjected to considerable pressure, as by being stepped upon directly over the patch bya person ,56 walking .on the rug.

rug is usually l insuiiicient to cause such patches to adhere and become effective.

. 'One object of my invention is t'o `provide an attachment for such coverings `which will be free from the-disadvantages mentioned. Another object is to provide such a covering with a readily attached frictional holding surface which will not 'materially procause local wear, and which shall be adapted for frictionally holding rugs of'a soft texture, such as oriental or tu ted pile rugs of -various' orirregular patterns or structuresy .of fabric.

Another object isto provide a structure adapted to adhere to a support by the mereweightof the fabric to which it is applied, and other objects are to providean addition to existing fabrics for the -above and other purposes adapted to be applied rapidly and with economy of time and ma'- .terials v In the accompanying drawings, 'Figure 1 is a schematic section through a fabric illustrating one form of my invention.;

Fig. 2 is 'an under plan view of' a rug comprising one application of my invention;

Fig. 3 is an underplan view of anoriental rug illustrating another lapplication thereof;

Fig. 4 is a schematic section of anAX- minster 'cai'petfabric illustrating another embodiment'ofmy invention; and Fig. 5. shows my invention in connection .with a fabric o f the ingrain type. Referring nowto Fig. 1, the fabric therein shown comprises warps 1 and a knotted weft pile 2, being typical of oriental and 'othertufted pile fabrics, wherein the soft yarn of the ornamental pile surface reaches the'back and forms the surface of the fabric which restsupon the floor or other support therefor. Fabricsof other types, such as Axminster fabrics, Fig. 4, in which stufer yarns are used' to give body aresometiinesl treated with a lue or starch size or other stifening material, but fabrics of the class above mentioned are not. customarily so treated.

For the purposes of my resent invention, I first apply a coating a apted to become adherent to or incorporated by a shallow penetration only with all or portions only of the back face of the fabric. As illus-y 110 trated in Fig. 2, lines 3 forming closed rectangular figures, for instance, may be applied to the back of therug. These lines are formed by padding, stenciling or painting with a brush, or by other suitable means of applying the sizing material, the result being an adherent, non-absorbent coating 4, as illustrated in Fig. l, at the places Where the coating 4 is applied.

In some cases an in the treatment of some fabrics I may apply the coating 4 continuously upon theback surface of the rug or other fabric.

One vpracticable coating comprises an aqueous solution of glue suliiciently stiff to prevent much penetration of the cloth to Which it is applied, but I prefer a relatively stiff solution of rubber in naphtha or other volatile solvent, sparingly applied, or an alcoholic or other non-aqueous solution of certaingums or other colloids such as pine resin, tragacanth or other commercial gums.

One purpose of the coating 4 is to fill the interstices of the back face of. the lfabric to prevent absorption into the fabric of a subsequent sticky coating, Which purpose'vvill be carried out When the application 1s of.

any composition ofV matter furnishing a coat rendering the back of the fabric impermeable to another superposed coating after the first or sizing coating 4.is dried or set. I may, for instance, make av coating 4 of an inert substance such yas celluloid, using azsolution in acetone, or employ any other suitable varnish or plastic to form a layer resisting penetration into the fabric of. the

rug of a liquid or semi-liquid adhesive coating to be applied over the coating 4, continuously or at places only, to enable the rug or other fabric to adhere to the floor or other support. I 'Wish to emphasize the importance of the coating 4, since I have found that Without such an, application it is diiiicult and commercially impracticable to apply a sticky coating in sufficient volume for my purpose Without causing it to penetrate to and spoil the face of the fabric, or to be Wastefully absorbed, or to affect the texture of the fabric detrimentally. n

Rugs of the type mentioned are improved as articles of use and Wear by the applica tion of such a coating 4, which' has the effect of preventing llongitudinal or transverse elasticity of the rug, Without materially affecting its iiexibility.

'I now apply upon the sized area in a Huid' canized ummy substance having the quality of adheslon Without complete attachment to polished surfaces. The solvent mentioned may be replaced by other suitable solvents" such as carbon tetrachlorid or, in the case of crude rubber, and preferably, a solvent comprising two parts of naphtha to one part of carbon tetrachlorid may be employed, thcrubber being dissolved in the solvent until the solution is in the-condition of yfree-flowing paint. x

In some cases I find that the objects of my invention may be attained by painting a coating 4 of the adhesive solution above mentioned on the back of the rug or other fabric Without previous treatment, the procedure in that case being first to stretch the rug or other fabric, and then to give it a light, continuous coat of the adhesive substance, Which is permitted to dryl While the rug remains stretched. A second coat 5 suitable to adhere to the ioor of the ad hesive substance may' now be applied in larger quantities Without danger of penetrating the fabric of the rug so completely as to affect its Wear surface. A The second coat may be applied continuously or, if desired, may be applied in a pattern such as that shown in Fig. 2.

In some cases I prefer, as illustrated in Fig. 3, to apply the coatings 4 and 5, or

the coating 5 only on the elements of the tile non-aqueous solvent, a rug so treated bef i ing capable of being Washed repeatedlyv Without removing the adhesive coatings or damaging their quality of adhesion.

When a .rug so treated is placed onthe l fioor, adhesion by its own Weight is sufficient to prevent slippage when the rug is stepped on. Other advantages follow, for instance the prevention of curlin of the corners, the-coating having a mar ed effect to prevent folds or curling at the ed es. If desired, lines of sewing stitches 7 ying transverse to the edges may be applied at the corners of the rug'prior to coating with the siz-A ing or the adhesive coatings 4 and 5, forthe complete prevention of curling atthe corners.

When the coatin has been applied, the solvent is driven o Yby exposure to dry -air or to heat, or both. The residual coatin 5 retains indefinitely the quality of adhesion to surfaces such as glass, marble, tiling, and polished or varnished wood under very thereof an adherent slight pressure such as the 'weight of the fabric, and I find rugs, and mats made by the above described method tobe safe against slipping in situations in which any of the structures of the present art ofv which I am aware, except positive fastening means, are liable to slip.

lVhat I claim is:

l.y A rug or mat having on one face a sizing coating and a superposed adherent plastic coating of an adhesive substance.

2. A rug cr mat having on one face an adlierent'coating incorporated by shallow penetration only with one face thereof, andan adhesive coating superposed upon and plastically adherent to said first-mentioned coatl ing. A

3. A rug or mat having on one face an applicd pattern or figure comprising areas of a sizing coating and a plastically adherent superposed adhesive substance.

4. A rug or mat having on one face a coating comprised of an adherent substance insoluble in water, and an adhesive coating plastically applied to and superposed upon said adherent coating.

5. A rug or mat having an adherent sizing coating on one face thereof of a sub'- stance insoluble in water, and an adhesive coatingof a rubber compound remaining sticky when dry. l

6. A rug or mat having on the back face sizing coating and an adhesive coating adapted to clin to a 'polished floor orother support, am? composed` of a gummy substance remaining as a -residue after the evaporation of a volatile solvent. l n

7. The method of renderingrugs, mats or other coverings adherent with respect to a supporting surface, comprising first coating .the back of a suitable textile fabric with a sizing coating of a consistency adapted to adhere without penetrating to the front sur- I face of said fabric,

drying said coating, and then applying in a plastic condition a coating of a sticky substance dissolved in a volai plastic condition a coating of an ad esive containing solvent.

9. The method of treating rugs, mats or other coverings to cause them to be adapted to cling totheir supporting surface, comprising first treating the back of a suitable fabric to render it impermeable, then applying in a plastic condition an adherent coatrubber dissolved in a volatile ing of a sticky substance dissolved in a vola-V ltile solvent, and then evaporating the solvent.

Signed by me at Boston, Massachusetts this seventeenth day of January 1916.
