LEAD-FLATTENING PRODUCT FOR LEAD PAINTS.

No Drawing.

To all whom may concern:

Be it known that I, WALTER E. WRIGHT, a citizen of the United States of America, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Lead- Flattening Products for Lead Paints; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to an improved lead-flattening product suitable for use in making lead paint, and pertains more especially to a lead-flattening product adapted to be mixed with commercial keg-lead consisting of white lead and linseed oil in Y the proportion of about eight pounds of linseed oil to about ninety-two pounds of white lead and thinned by the addition of turpentine, benzin or other thinning vehicle to produce a lead paint which can be freely applied with a paint-brush.

The object of this invention is to produce a lead-flattening product the mixture of which in suitable proportion with ordinary commercial keg-lead thinned with turpentine, benzin or other thinning vehicle, results in the production of a lead paint that will dry to a dull or flat finish while thinned to the consistency of paint and which can be freely applied with a brush without showing brush-laps.

The present invention more especially pertains to a lead-flattening product of the character hereinbefore mentioned comprising Chinese tung oil, a semi-drying oil, such, for instance, as soja bean oil or cotton-seed oil, and a suitable varnish, such, for instance, as a heavy body resin-gum and oil varnish which is adapted to adequately mix with and to set more rapidly than tung oil. In lieu of the semi-drying oil mentioned a non-drying oil, such, for instance, as paraflin oil, may be used.

I would here remark that linseed oil dries with a tough and elastic skin which makes it the most desirable oil as a binder for a lead paint, and that linseed oil dries too quickly for a fiat paint, but in a coat of palnt involving the use of my improved lead flattening product the drying of the linseed oil is retarded by the semi-drying oil or non-drying oil hereinbefore mentioned. I would also remark that said semi-drying oil or non- Specification of Letters Yatent.

drying oil is found to be undesirable and impractical without the presence of a suitable quantity of the hereinbefore mentioned tung oil which of itself dries with a waxy film and which is the strongest drying vegetable oil known and which when used in proper proportion produces a catalytic condition and formation with linseed oil, the hereinbefore mentioned semi-drying oil or nondrying oil, whitelead and turpentine or petroleum distillate.

In making my improved lead-flattening product the tung oil and the hereinbefore mentioned oil employed in retarding the drying of the tung oil are preferably mixed, and then with said mixture of said oils is mixed the hereinbeforementioned varnish to produce the desired lead-flattening product which is ready for mixing with previously thinned commercial keg-lead so as to produce a lead paint which will dry to a dull or flat finish while said lead-flattening product is thinned to the consistency of a paint that can be freely applied with a Ibrush without liability of showing brushraps.

To each pound of tung oil employed in making said lead-flattening product I preferably use from about one-eighth of a pound to about one and one-half pounds of the hereinbefore mentioned varnish and from about a half pound to about five pounds of the hereinbefore mentioned oil employed in retarding the drying of the tung oil. I would here remark that I have obtained highly satisfactory results by using the varnish, the tung oil and the oil for retarding the drying of the tung oil substantially in the proportion of two pounds of the lastmentioned oil and one-half pound of the varnish to one pound of the tung oil. There fore, I prefer, in making my improved leadflattening product to use about a half pound of the varnish to about three pounds of the mixture of tung oil and soja bean oil. That is, the quantity of tung oilused is preferably less, by weight, than the quantity of soj a bean oil used, and considerably more, by weight, than the quantity of the varnish used.

I would also state that in making a lead paint involving the use of my improved leadflattening product from about one to about eight pounds, and generally about two pounds, of said. lead-flattening'product are used with about one hundred pounds of the commercial keg-lead which has been suitably thinned with turpentine or other thinning; vehicle.

What I claim is- 1. A lead-flattening product adapted to be used in making lead paint and comprising tung oil, an oil which when mixed with tung oil retards the drying of the tung oil, and a varnish adapted to mix with and to set more rapidly than tung oil, said; varnish, the second-mentioned oil and the tung oil being substantially in the proportion of about onehalf of a pound of the varnish and about two pounds of said second-mentioned oil to about one pound of the tung oil.

2. A lead-flattening product adapted to be used in making lead paint and comprising tung oil, an oil which when mixed with tung oil retards the drying of the tung oil, and a heavy body resin-gum and oil varnish,

l 3. A lead-flattening product adapted to be used in making lead paint and comprising tung oil, soja bean oil and a varnish adapted to mix with and to set more rapidly than tung oil, said varnish and the aforesaid oils being in the proportion of from about oneeightb. of a pound to about one and one-half pounds of the varnish and from about a half pound to about five ounds of the soja bean. oil. to one pound of t 1e tung oil.

4. A lead-flattening product adapted to be used in making lead paint and comprising tung oil, soja bean oil and a heavy body resin-gum and oil varnish, said varnish and the aforesaid oils being substantially in the proportion of about one-half pound of the varnish and about two pounds of the soja bean oil to about one pound of the tung oil.

5. A lead-flattening product adapted to be used in making l ad paint and comprising tung oil, an oil which when mixed with tung oil retards the drying of the tang oil, and a varnish adapted to mix with and to set more rapidly than tung oil, said varnish being used. in considerably smaller quantity, by weight, than the tung oil, and the tung oil being used in smaller quantity, by weight, than the second-mentioned oil.

6. A lead-flattening product adapted to be used in making lead paint and comprising a varnish adapted to mix with and to set more rapidly than tung oil, and a mixture of tung oil and an oil adapted to retard the drying of the tung oil, said mixture of oils and the aforesaid varnish being in the proportion, by weight of a considerably larger quantity of said mixture of oils than of the varnish.

In testimony whereof, I sign the foregoing specification, in the presence of two witnesses.
