WATERPROOFING FOR CLOTH.

6 Wyandotte and State of Kansas, have mvented certain new and useful Improvements in Waterproofing for Cloth, of which I the following is a specification.
The object of this invention is to make 10 a more perfect water-proofing for -cloth that will turn the water under any conditions of weather. Cloth treated by this process has its period of lifeincreased for not only is the fabric protected from moisture but the ingredients that render it water-proof have no deleterious effect on the fibre.
Because of the excellent water-proofing action of the ingredients as used in my process, the cloth'is not as stiff as is the case. code, for a thilnner coating accomplishes-t e same resu t. Another object of my rocess is to pro- 'duce a cloth which will e absolutely imervi'ous to water and will not crack when olded.
With these and other objects in view, xthe invention consists of a process as herein set forth, With the understanding that the sev-.
o eral necessary elements entering into the composition may be varied in proportion without departing from the nature and scope of the invention.
To make the water-proofing, a small quan- 3e tity of rubber iscooked in boiling oil until the rubber has become thoroughly dissolved. Any. of the heavier hydrocarbon oils may be used or a vegetable oil, as linseed or cotton seed oil. The vegetable oils have been found: to be superior to the mineral oils, but it will be "understood that the invention is not limited to the exact type of oil used.
To the hot mixture of oil and rubber is added a small quantity of asphalt. To this mixture is then added a finely comminuted filler, such as pulverized calcium carbonate or ferric oxide. The exact composition of the body does not form art of this invention as any of the inso uble mineral salts or oxides accom lish the same result,
It has been ound by actual experiment that good roportions of the ingredients used are as ollows:
Fi er to The stiffness of the com ound is deter: mined by the proportion o filler added.
The rubber has theproperty of acting as a binder to keep the as halt from separating from the oil whic would otherwise be its tendency when allowed to stand. The asphalt likewise keeps the finel ground filler in solution and does not a low it to precipitate. greater the amount of ground filler added the greater the amount of asphalt necessary and likewise the greater the quantity of rubber: The rubber has the complemental efi'ect on the asphalt that the asphalt has on the filler, i. e., that of holding it in solu-' tion or of forming-a blend. When the water-proofing composition has been pre- Thus it will be seen that the pared a proper coloring may be given to it by means of any suitable pigment.
The watenproofin composition may be ap lied to the fabric y means of a brush or rol er and the fabric is allowed to dry or set from nine to eleven days. The composition has a tendency to become very v scid,
uents and the even grade of the compound, regardless of the length of time it has remained in the container.
Having set forth my invention, whatl claim is 1. A water-proofing composition composed of a hea hydro-carbon oil, asphalt, rubber and a er.
2. A water-proofing composition composed of a heavy hydro-carbon oil, approm'- mately 40 to 50 per cent, rubber 5 to 10 per erature absolutely and unicent, asphalt 5 to 10 per cent, and a filler composition consisting of boiling 40 to 50 30 to 50 per cent. parts of heavy hydrocarbon oil with 5 to 3. A process for makin Water-proofing 10 parts rubber, adding 5 to 10 parts as- 1 v composition consisting of oiling a heavy ghalt and then adding a filler of thirty to 5 hiyidro-carbon' oil with rubber, adding asfty parts. v p alt and then adding a filler. In testimon whereof I afix my signature.
