LIQUID COATING COMPOSITION.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed February 7, 1907. Serial No. 356,195.

To all whom it may concern:

Be it known that I, Lnwrs EDGAR ODELL, residing at New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Liquid Coating Composition, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates broadly to a process and meangor coating various bifildiiig madteriafs, but s'irfcecertam advantages c'han acteristic of the invention prominently appear when it is resorted to for the purpose of preserving wood it will be conducive to clearness to describe an embodiment thereof as apglied in such connection.

ne object of this invention is to formulate a commercially practicable method of preserving wood which is adapted for being yery readily carried out at a low cost.

Another object contemplated by this invention is to obtain a certain new and improved preservative whose in redients will be cheap and readily obtainab e, and which when applied will very effectively accomplish its urpose.

ther objects and advantages will be in part obvious and in part pointed out hereinafter.

This invention accordingly consists in the several steps and the relation and order of one or more of such steps with relation to each of the others thereof which will be exem lified in the process hereinafter described, an the scope of the ap lication of which will be indicated in the fol owing claims.

vMore specifically, this invention pro oses a coating composition comprising an a kaline agent such as slaked lime, and a preservative such as charcoal. These ingredients will preferably be suspended in a suitable liquid carrier which is well adapted to penetrate the pores of wood so as to impregnate the same with the composition.

In preparing the coating composition the lime may be slaked and" mixed with boiled linseed oil or turpentine, and to this emulsion will be added finely powdered carbon, which may be in the form of charcoal, lamp black or any of the other commerciallv obtainable equivalents. These ingredients will be intimately ground together and thoroughly emulsified with the carrier so as to form a smooth flowing paint.

It is to be understood that various proportions of the foregoing ingredients may be employedthus 46 parts of mixed with 54 parts of'charc, an suffie cientpil will be employed to form a freely flowing paint, and it is also to be understood that in some cases other materials may also be added, but the foregoing embodiment is that which will ordinarily be preferable to employ in practice, and is regarded as representin substantial improvements over the many implied and obvious variations of the same.

In ap lying this paint, which in ractice will be ound to be of a grayish co or, the wood will preferably be in a relatively dry state, and the paint may be applied directly thereto so as to thoroughly impregnate and cover the superficial surface of the wood. This impregnation may be accomplished in several ways, and in some cases may be forced into the pores of the wood through the It is also.

application of external pressure. proposed to successively apply a series of coatings of paint prepared in the foregoing manner. Thus, the first coating may be com,-

v a ILQ paratively thin, so that a very perfect imclaim as new and desire to secure by Letters Patent is 1. A preservative coating composition which constitutes an emulsion consistin of 9 ialka 1]1Q material.

2.1K preservative coating composition owdered charcoal, and a pulveru ent which comprises slaked lime, a neutral pulverulent carbonized material, and an oily carrier holding said ingredients in suspension. 3. A preservative coating composition which comprises approximately 46 parts of powdered lime to 54 parts of powdered charcoal, and an oily carrier.

4. A preservative coating composition which comprises approximately of 46 parts of powdered lime, a proximately 54 arts of a 10 powdered carbonized material, an a liquid carrier.

In testimony whereof I affix my signature, in the presence of two witnesses.
