OF CHICAGO, ILLINOIS WATERPROOFING PRESERVATIVE .DRESSING.

Specification of Letters Patent.

Patented June 1, 1909.

Application filed June 17, 1908. Serial No. 438,952.

To all whom itmay concern:

Be it known that I, JULIUs HENRY HOEL- soHER, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Waterproofing Preservative Dressing, of

I which the following is a specification.

This invention has for its object the prep aration of a fluid dressing adapted for app if cation to leather of any kind or to fabric to leather or fabric to which applied to fill or render the same water proof and to preserve the same.

It is an object of this invention to provide a .fluid dressing adapted to permeate the I artlyfill the intercellular s aces, capillary servative adapte any atmospheric temperature and w ich e articles to which applied in a bers and the interstices t erein with an elastic substance of slightly oily nature which resists the penetration of water.

3 It is a further object of the invention to provide a water (proofing dressing and preto maintain its fluidit at maintains t soft and pliable condition.

Finally it is an object of the invention to afiord an antiseptic water proof dressing of such a nature as to be immediately absorbed in the material to which applied leaving the surface thereof in a condition to receive a polish or other treatment should it be desired.

It is also an object of the invention to rovide a transparent, colorless dressing w ich will not affect the color' of the article to which applied.

The invention consists in the matters here inafter described and more .full pointed out and defined in the appended c aims.

In preparing the dressing a gum or resin is mixed with an oil and with alcohol or a fluid adapted to assist in cutting the gum, in proportions adapted to form arelatively thin fluid. For this urpose I prefer to use sandarac resin as t e gum,-thou h other gums or resins might be substituted. This is cut withalcohol of any kind though conveniently wood alcohol may be used, and tothis an oil, preferably a vegetable oil, such as castor oil is added to afford a solution in which sufiicient of the oil is taken to hold the gum in a semi-fluid or viscuous condition after the-evaporation of the alcohol.

. One satisfactory preparation is rovided by using approximately three poun s of sandarac resin, five gallons of castor oil and ten gallons of alcohol. The resulting thin and slightly viscous fluid is then bottled or placed in hermetically sealed cansand retains its fluidity and may be applied at any atmospheric temperature.

In applying (as for example to shoes of any kind) t e preparation may be spread by means of a brush very freely into and upon the seams and soles, a thinner coating apdressing effectually shed water without in-- jury to the appearance of the shoe. When used for water proofing fabrics as a substitute for oil skins or for use as tarpaulins or for any other purposes, the nature and fluidity of the preparation are such that the capillary fibers of the fabric take up the preparation very rapidly retaining the same therein and being somewhat distended by the same, thus filling the interstices and rendering the same Water proof. The slightly oily nature of the material, after the evaporation or partial evaporation of the alcohol, prevents the adhesion of moisture to the fabric, thus reventing the enetration of the fabric there y, though sue oily texture is not sufficient to be distinguishable to the touch or to soil or injure any fabric brought in con tact with the water proofed garment.

The elasticity of the dressing serves to render the fabric in a soft and pliable con dition, and inasmuch as all the" ingredients are antiseptic in their character, a perfectly sanitary dressing is secured and one that wi not deteriorate lnany climate or under any natural conditions. 1

Of course, I am aware that otheringredients may be added if preferred, the proportion may be varied. These in some instances, however might render the article treated unsightly and in some instances might prevent the leather or fabric from perfectly absorbing the dressing thus losing a very important feature of this invention, namely, that the dressing does not affect color and when ap lied is 'uickly absorbed leaving but very shg t visib e trace, if any.

Inasmuch, as changes in ingredients and ]proportions may be varied, I do not purpose 'mlting this application for patent otherwise than necessitated by the prior art.

I claim as my invention:

1. An antiseptic and preservative water proof: dressing comprising less thanfive per cent. gum, a more or less volatile liquid to cut the same and a vegetable oil of substantially one-half the quantity of the volatile liquid mixed therewith to afford in connection with the gum an elastic and slightly oily medium adapted to be retained in the interstices in the articles to which applied after the evaporation of the cutting fluid 1 therefrom.

2. Water proofing and preservative dresslng conslsting of a small per cent. of sandarac resin, castor oil and alcohol in proportion approximately one to two, and said redients affording a thin, transparent, orless fluid. 3. A preparation of the class described consisting approximatel of three pounds of sandarac resin, five gal ons of castor oil and ten gallons of alcohol;

In testimony whereof I have hereunto subscribed my name in the presence of two sub scribing witnesses:

JULIUS H. HOELSCHER.
