UNITED STATES VALENTINE J. HANSEN, OF OKLAHOMA, OKLAHOMA.

COMPOSITION FOR CLOSING THE MESHES OF WIRE FABRIC.

No Drawing.

To all whom it may concern: I

Be it known that I, VALENTINE J. HAN- SEN, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Compositions for Closing the Meshes of Wire Fabric, of which the following is a specification.

The present invention relates to a novel composition of matter for coating and closing the meshes of woven wire fabric, thereby providing a translucent or opaque sheet which can be used as a substitute for glass, or as a surface upon which to paint signs and advertising matter.

Further objects of the invention are to provide a composition of this character which can be prepared at a comparatively small cost, which can be easily mixed, which can be readily applied to the conventional woven wire fabric and the like found upon the market with most satisfactory results, and which can be tinted with any desired color for the purpose of producing an ornamental appearance.

In carrying out the invention separate quantities of paraffin oil, mastic gum and copal varnish are obtained, the paraflin oil being initially cut with benzin or turpentine,

the mastic gum being initially cut with alcohol, and the copal varnish being also initially cut with alcohol. These three ingredients are then brought together in substantially the following proportions.

4 parts of the cut paraffin oil.

3 parts of the cut mastic gum.

3 parts of the cut copal varnish.

A composition mixed in these proportions has been found by experiment to give excellent results, although it will be understood that these proportions can be varied within reasonable limits.

The cut parafiin oil, out mastic gum, and cut copal varnish, after being brought together in the proper proportions, are heated, preferably to the boiling point, and thoroughly stirred, thereby preventing burning and mixing the ingredients into a perfectly homogeneousproduct. WVhile the products are being stirred, a quantity of raw linseed oil, suflicient to give the mixture the proper consistency is added, enough litharge to cause the composition to dry quickly without becoming brittle being simultaneously introduced into the mixture. Just a sufficient Specification of Letters Patent.

quantity of linseed oil is added to give the m xture the proper consistency to be handled with a brush or to be used as a dip.

The screen or woven wire fabric should be thoroughly cleaned before applying the composition thereto, and this can be readily accomplished by dipping the screen into a solution made by mixing three parts of acetic acid and one part lime water. This removes all grease and foreign matter from the screen so that the coating will readily adhere thereto and close "all of the meshes in a uniform manner. it has been found that the ordinary aluminaun and galvanized screen, as now found upon the market, will take the coating perfectly, after being thoroughly cleansed, as indicated above.

The mixture produced as above described may be applied to the screen, either in a hot or a cold condition,.and either by dipping the screen into the mixture or by distribut mg the mixture upon the screen with a brush. Good results have been obtained, however, by applying a coat of the mixture to the screen in ,a cold condition, and subsequently applying a second coat of the hot mixture after the first coat has been permitted to dry thoroughly. The-mixture will close all of the meshes of the wire screen in a uniform manner when first applied, and the meshes will not reopen as the mixture dries. The coating is very tough and durable, and is at the same time flexible, thereby permitting the screen to be bent sharply without breaking the coating. When the mixture is prepared without the addition of any pigment, a translucent sheet will be provided, and this could be employed in many instances as a substitute for glass where a tough translucent sheet which is not brittle and will not break is desired. The composition can be tinted by the addition of vermilion red, chrome yellow, or emerald green. On the other hand, if an opaque sheet is desired, lampblack can be applied to the mixture.

A sheet of woven wire fabric which has been treated with this mixture, said mixture closing all of the meshes thereof so as to provide a continuous surface on each side there of, can be used for many purposes, such as for the manufacture of signs. Any kind of advertising matter can be easily printed or painted upon the sheet in such a manner as to produce a. most effective display thereof. since the sheet presents a very novel and pleasing appearance, analogous in many respects to that of the linen finished papers, which are used toa great extent in preference to smooth surfaced papers.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is r l. A composition of matter for closing the meshes of woven wire fabric, including a mixture of cut paraffin oil, out mastic gum, and cut copal Varnish.

2. A composition of matter for closing the meshes of woven wire fabric or the like, including a mixture of cut paraffin oil, out mastic gum, cut copal varnish, linseed oil and litharge.

3. A composition of matter for closing the meshes of woven Wire fabric or the like, including amixture of paraffin oil, sufficient turpentine to cut the paraffin oil, mastic.

gum, sufficient alcohol to cut the mastic gum, copal varnish, and an additional quantity 'of alcohol suflicient to cut the copal varnish.

4:. A composition of matter for closing the meshes of woven wire fabric or the like, including a mixture of four parts of paraffin oil, three parts of mastic gum, three parts of copal varnish, suflicient drier for the paraffin oil, mastic gum and copal varnish, linseed oilin sufiicient quantity to produce the proper consistency for handling, and litharge in sufficient quantity to dry the coating quickly without making it brittle.

5. A composition ofmatter for closing the meshes of woven wire fabric or the like, including a mixture of four parts of paraffin oil, sufficient turpentine to cut the paraffin oil, three parts of mastic gum, three parts of copal varnish, suflicient alcohol to cut the mastic gum and copal varnish, linseed oil in sufficient quantity to produce the proper consistency for handling, and litharge in sufficient quantity to dry the coating quickly without making it brittle.

6. The method of preparing a composition of matter for closing the meshes of woven wire fabric or the like, including the preliminary cutting of paraffin oil, mastic gum and copal varnish with a drier, and the subsequent mixing of the cut paraflin oil,

out mastic gum, and cut copal varnish, to-

gether with linseed oil and litharge.

Witness my hand this 4 day of June,
