WATERPROOFING SOLUTION.

80 Drawing.

To all whom it ma concern: Be it known t at we, RALPH MICHAEL MEAKES and GEORGE FREDERICK VVILLIAMS, both subjects of the King of Great Britain, and both residents of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Waterproofing Solutions, of which the following is the specification.

Our invention relates to in'iprovements in water proofing solutions and the object of the invention is to devise a water proof solution which can be applied on canvas, fabric, wood and other materials which will render the same water proof.

A further object is to devise a water proofing solution that will permeate the fibres of the material treated and which will be exceedingly durable, as well as being light in weight and which will not appreciably affect the flexibility of the treated material.

A still further object is to devise a water proofing solution which when applied to fabrics will not shrink the same. 7

In carrying out our invention we use the following ingredients:

8 ozs. algae, 6 ozs. castile soap, 6 ozs, glue, 1 qt. double boiled linseed oil, 1 gal. water.

The method of preparing the solution is to mix the moss and soap in the above proportions in the water which is then brought to the'boil and the glue dissolved therein.

The mixture is then diluted with a quart of double boiled linseed oil which brings it to the proper consistency for applying to the fabric or other material.

Of the various forms of algae that may be used for achieving the desired result we prefer to use Irish moss (OILO-HCZTUS ma'spus).

\Ve are aware that prior to our invention Irish moss or other forms of algae have been used either by itself or with other ingredicuts as oil proof coatings and as a dressing for fabrics and we make no claim to the same broadly but only to our composition of matter as set forth in the appended claim.

If the Irish moss were used by itself dissolved in Water it would become sticky and would eventually be dissolved if subse- Application filed June 30, 1924. Serial No. T723343.

quently immersed for any considerable period in water, or if Water were applied thereto. This would occur owing to the absence of any ingredient that would tend to harden the algae. For this reason glue is used, which when mixedwitlr the algae renders it practically insoluble when water is applied to the fabric or other'mat'erial treated. -The castile soap gives pliability or flexibility to the fabric treated whenicombined with the other-ingredients and thus obviates the cracking of the fabric or other treated material when it is bent, which would otherwise render the water proofing properties ineffective owing to the water getting through the cracks even though each fibre of the material were impregnated. The linseed oil enhances this quality and gives body to ,the'solution, facilitating its application to the material to be treated.

The solution is intended as an underlay for paint on fabrics, wood and other material and the method of application is to treat the material with the solution by applying it with a brush, working it thoroughly into the fibres of the material whereby each fibre is impregnated. The material is then painted with the desired number of coats of paint and the resultant product in the case of canvas, linen or other fabric, is exceedingly pliable and is not susceptible to cracking as so frequently occurs with and the like at present in use.

lVhere the material treated is not itself pliable, as for instance in wood, it is still essential that the solution posses the prop erty of rendering pliable the paint or varnish coats subsequently applied thereto as this prevents the paint or varnish drying hard which would tend to impair its waterproofing qualities and render it liable to blister as now occurs where no such underlay as our solution'is used.

7 What We claim as our invention is.

A composition of matter consisting of 8 ozs. of Irish moss, 6 '02s. of castile soap, 6 ozs. of glue, dissolved in 1 gal. of water, to which is added 1 qt. of linseed oil.
