7 '0 all whom it may. concern:

Be it known that I, CARLETON ELLIS, a citizen of the United States, residing at Montclair, in the county of Essex and State of New. Jersey, have invented certain new and useful Improvements in Cloth-Tinting Compositions and Processes of Tinting Cloth, of which the following is a specification. I

This invention relates to a process of treating the lining of automobile tops and relates especially to a method of spraying a tinting composition on such linings and to a composition' adaptedfor such tinting par-- 15- oses. tp The invention is concerned especially with the revival or renewal of the linings of automobile tops such as the ordinary touring car top which has an outer fabric of leather or leather substitute and an inner lining of cloth which is usually loosely attached to the outer covering. The inner cloth lining very quickly becomes weather stained and streaked from water and dust and becomes unsightly. While the outer fabric may be treated with leather dressings to restore its appearance, heretofore there has been no satisfactory way of reviving the interior or lining.

Accordin to the present invention, inits preferred orm, a solution is made in a h drocarbon solvent of a dye which is solu le in such solvent but insoluble in water.

' The oil soluble dyes now on the market and used in varnish stains may be employed for the purpose. They are sold under various names and are readily obtainable. Ordinarily I prefer to use a stain which gives a brown, drabor mahogany tint. It is desirable to have the solution strong enough in dye to adequately cover the water stains of the fabric. It is also desirable to have resent a small amount of resin to better old the dye in place and to serve to slightly un esirable to use a heavy bodied varnish basis or an hing of this description because it ren ers the fabric stiff and also may Specification of Letters Patent.

brighten the fabric. On the other hand it is.

2% and 8% satisfactory results are obtained. The resin is calculated on the weight of solvent employed. The resin also serves to some extent as a Waterproofing agent so that when cloth so treated is again exposed to rain water stains do not form as readily.

A suitable solvent vehicle is benzol or toluol but preferably varnish painters naph the or heavy benzine is used. 'A mixture of benzine and benzol may be employed.

The proportion of the oil-soluble color may be approximately one per cent but may vary more'or less according to the intensity of the tint desired.

A suitable composition is made by dissolving 2% 'of cumaron resin in a solvent composed of 90% of varnish makers naphtha and 10% of benzol and adding a mixture of one part of oil-soluble orange stain to two parts of oil-soluble oak stain, the proportion of oil-soluble dye in this case is one gives-a brownish tone with per cent. This a slightly reddish tint which quite effectively covers the weather stains on the fabric.

If such a composition were'applied' with a brush it would be diflicult to make even application but by. means of spraying the composition may be applied uniformly. However if a sprayer does not work properly and drops of the composition fall on the fabric the resulting blot is difficult to cover by subsequent coats of the composition as applied by spraying.

However I the spray to-the cloth from the underside when' the cloth is in a horizontal position as for example inits normal position in the au-' tomobile top.

One feature of the invention therefore is that of spraying a composition of this character in a substantially vertical position against the fabric thereby overcoming the danger of not securing a uniform -applica-' find that it is possible to apply tion. Hence it is possible'to treat-the fabric from the machine.

Other resins or binders such as shellac, ordinary rosin, rosin ester and drying oils such as linseed oil, wood oil, etc., may likewise be' used in some cases. However a resin which-is substantially unafi'ected by water, that is does not turn white or change in the automobile top without its removal. 9

in appearance on contact with water is pr'eferre Othermixtures may-be used. which have a.

water-proofing effect as for example a solution of paraflin or better ceresin wax in benzol or toluol. This is tinted with the oil soluble dye. 2 or 3% of wax sufiices to'secure desirable waterproofing results but the wax may be increased if desired. Non-inflammable solvents such as trichlorethylene.

or carbon tetrachloride may be used.

Ordinarily a quick drying composition is desired as the fabric is preferably quite thoroughly wetted with the solution and with slow drying materials present the liiring would require a rotracted exposure in order to render the fa ric perfectly dry. By the use of small quantities of resin in this manner a binding effect may be secured without the employment of drying o'il.

Other solutions such as alcoholic solutions of dyestufl's which are insoluble in water may likewise be employed but as a. rule do not give as satisactory results. It is also possible to spray a water'soluble dye as for example an aqueoussolution of a dyestufi' on the fabric and subse uently treatwith a mordant or fixative. owever the present emma process involving the use of a dilute resin solution containing an oil soluble but waterinsoluble dyestuff and sprayed vertically against the fabric accomplishes very satisfactory results at a low cost and with a simplicity of operation which is desirable. The top does not have to be removed from the body of the car in order to treat it. This preferred method therefore is recommended
