able others. skilled in the art to which it appertains to make and use the same.
The invention relates to compounds for preserving timber.
It has for its object to provide a compound possessing'preservative and antiseptic properties and which tends to solidify when injected into the pores of the wood, and which is insoluble in and practically unaffected bywater. and practically unaffected by atmospheric conditions as to heat,
- so far as concerns the larger percentage of the compound, thus producing a wood preservative compound having greater stability and possessing the necessary properties to resist the disintegrating influences of bac teria and fungus life.
To the accomplishment of the objects stated the invention consists in the compound hereinafter. described and particu- The compound is formed by thoroughly mixing. under natural or artificial heat, preferably at a temperature of approximately 150 Fah., dead oil of coal tar, otherwise known as creosote oil. and crude petroture or compound is to be used, a smaller proportion of creosote oil being employed where the compound is to be used in preserving timber used on land or in dry climates than where the timber is to be used. in wet cllmates, in. swamps, in running water, or in salt water where protection is desired against thesalt water worms and borers such as the Teredo and Limnom'a. The proportions accordingly can be varied For cross ties and timbers used under ordinary conditions on land, the economical and effective mixture is 20% to 25% dead oil of coal tar (creosote) the balance being crude oil having an asphaltum base. For piling and timbers used in water the mixture may be as high as 50% of each -constituent. The crude oil employed is preferably that which has hadremoved therefrom the ordinary kerosene oil and if desired also lubricating oil and gasolene by distillation under any of the well known methods in use, or there may be employed crude petroleum having an asphaltum base from which kerosene, gasolene and lubricating oils have been removed by the ordinary well known methods in use for that purpose. In all cases however an essential ingredient of the compound is crude petroleum having an asphaltum base, mixed with dead oil of coal tar, or creosote oil.
Creosote oil or dead oil of coal tar, is the best known wood preservative, and is both antiseptic and waterproofing in its action. Crude oil having an asphaltum base is also antiseptic and the heavy portions thereof fill the wood cells and prevent the entrance of water. a
The, compound described has been found to contain approximately 90% of a stable body which-coagulates or solidifies in the wood cells, practically filling the cells and to a material degree remaining unaffected by atmospheric conditions or heat, and inunalfected by water, thus affording a waterproof as well as a preservative compound for timber, which materially prolongs the life of the timber, and at the same time possessing the beneficial result derived from the use of creosote or dead oil of coal tar, and at a materially smaller cost. The reduction in cost is very important, as the amount .soluble in and practically unimpaired or of treated timber used is almost wholly governed by the cost of treatment.
The compound'may be applied to the timher by methods well known in the preservation of wood by injecting preservatives into ing dead oil of coal tar, or creosote oil, and
crude petroleum having an asphaltum base from which kerosene, gasolene, and lubricating oils have been removed. 4. A Wood preserving compound contain.- ing creosote oil and a material containing the still bottoms of asphaltic petroleum.
5. A Wood preserving compound consisting of 1 part of creosote oil and from 1 to 3 parts of a material containing the still bot- 10 toms of asphaltic petroleum.
. 6. A Wood preserving compound containing 1 part of creosote oil and l to 3 parts of 'asphaltic petroleum from which the kerosene, gasolene and lubricating oils have been removed. p 15 In testimony whereof I afiix my signature in presence of two Witnesses.
