COATED rAisRro AND METHOD or MAKING SAME.

No Drawing.

To all whom it mayconcem:

Be it known that I, JOHN )Nrnsox, re-

siding at Elizabeth, New Jersey, have invented certain .new anduseful Improvements in Coated Fabrics' and Methods of Making Same, of which I declare the following to be a full, clear, and-exact descrip tion.

coated fabrics and the method of-inaking her-coated fabrics, such as may be used for the manufacture of raincoats, slickers', and similar products. The principal bject of my invention is. to produce a coated fabrichaving atough, resilient, and thoroughly waterproof coating 'which'is, at the same time, of light weight and maybe produced at a low cost. A further object of my invention is to provide an improved process, or method, for making coated fabrics, by which a light weight, waterproof, coated fabric may be produced at a low-cost. v

Further objects of my invention will definitely appear from the detailed description to follow. f

In general, I carry out the objects of my invention by applying to a.sui table fabric base a coating composition made up of a mixture of rubber and a chemically inert,

finely divided organic substance, such as comminuted cork or cork flour. This coating composition is applied to the fabric base in any suitable manner and then vulcanized on said base.

Ihave secured very desirable results by the use of a mixture of sixty (60) pounds of crude rubber and forty (40) pounds comminuted cork or cork flour.

added, as iswell known in the art, and one hun'dred twenty-five (125') pounds of naph+ tha are addedto the mixture to render it plastic or semi-fluid so that it can be worked and spread. j

This mixture is spread upon a suitable fabric base, for instance, napped moleskin,

' by the use of any suitable spreading or coating means such as are well known inthe art. After the coating composition has been spread on the fabric base, the evaporation of the naphtha leaves the coating partly cured, in the manner well-known in'the art,

The addition of the cork does not detract materially .from the toughness, elasticity and waterproofingqualities of the rubber and the cork serves as an/i'nert filler'which', since-it is of a low specific gravity, high resiliencyand isnot readily ermeable to without a large increase in weight. This enables me a quality equal or superior'to the eavier rubber-coated fabricsQheretofore I have found that desirable resu ts are sec'ure'd by the-use of cork as the filler, but I substitute other inert,, organicsubstances and also secure good results" 7/ I am aware that the particular embodiment of my invention 'here'. shown is susceptible 'of considerable variation without departing from the spirit thereof, and therefore, I desire to claim the same broadly, as well as specifically, as indicated by appended claims. I, j v

, Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. A coated' -fab ric comprising 'a'fabric base having applied'thereto a mixture of rubber and inert, resilient organic material of low density and not readily permeable to water.

2. A coated fabric comprising a fabric basecarrying a coating composed of a mix- Y vulcanizingthe coating on the fabric base.

silient material of low density and substantially non-permeable to water.

5. A coated fabric comprisinga fabric base carrying a vulcanized coating composed of a mixture of rubber and inert, resilient material of relatively low specific gravity.

6. A coated fabric comprising a fabric base carrying a vulcanized coating com-' posed of a mixture of rubber and comminuted cork.

7'. A method of making a coated fabric comprising, mixing crude rubber with a relatively inert material of specific avity less than one, adding an amount o evaporable or relatively fugitive substance to render the mixture fluid, applying the same to a fabric base, causing evaporation of said substance, and curing the applied coating.

' orable substance to render the mixture fluid,

applying thesame to a fabric base and thereafter vulcanizing the applied coating.

9.'A method of making a coated fabric which comprises mixing crude rubber-with an inert resilient organic material to form a light Weight Waterproof coating, adding a carrier to render said mixturevcapable of being applied to a fabric base, applying the same to a fabric base and causing an evaporation of said carrier.

10. A method of making a coated fabric comprising mixing crude rubber with a comminuted light Weight flexible material,

'adding to said mixture a carrier adapted torender the mixture capable of being applied to a fabric base, applying the same-to said fabric base, causmg an evaporation of said carrier and yulcanizing the said coating on said base. .1l. A method of making acoated fabric comprising, applying a coating, containing rubber and cork mixed to render the same capable of being applied to fabric, and vulcanizing the said coating on said fabric.

In testimony whereof, I affix my signature. I
