RUBBER COMPOUND 0R MBXTURE.
SPECIFICATION forming part of Letters Patent No. 391,927, dated October 30, 1888.
Application filed August 22, 1888.
To all whom it may concern:
to it known that I, John A.Trrznr.,of Glenshaw, in the county ofAllegheny and State of leimsylvania, have invented a new and useful ltubber Compound or Mixture, of which the followingisa full, clear, and exact description. "lhisinvention consists ofa novel compound, composition of matter, or mixture, in which vulcanized india-rubber (scrap or waste) is or may be utilized, and which, among other purposes or uses, is adapted for rendering various su rfaccs proof against the eifccts of either salt or fresh water, is capable ofresisting many or most solvents, also moderately-strong acid and al k alinesolutions, and that will stand both a high heat and extreme cold,and which may be used as apaint, varnish, baking'japan, or coating for eordagc, canvas, metal, wood, brick, stone, and other materials, audior insulating or protecting electric wires or conductors of any descriptiomeither above or below ground, where elasticity and durability are required. My improved compound is substantially composed of gilsoniic asphaltum, vulcanized 5 india-rubber, (scrap. or waste,) manganated linseed-oi], spirits of turpentine, dodorized petroleum naphtha, and powdered sulphur. To these various other ingredients may, if desired, be added, including diil'erent pigments or coloring materials, according to the purposes or uses the compound is designed for; but the several ingredients first above named virtually complete the compound, and when made in large quantities should be combined in about the following proportions, though these may be more or less changed: Gilsonite asphul nm, ninety pounds; vulcanized rubber, (scrap or waste)o'nehund red and thirty pounds;
manganated linseedoil, three and one-half toseven gallons; spirits of turpentine, nine gallons; deodorized petroleum naphtha,ninc gallons; powdered sulphur, ten to fifteen pounds; dependent on the quality of rubberviz., more or less adulterated.
For the purpose, however, of more clearly explaining my invention, I will now describe the making of a smaller quantity of the compound. Thus I take of gilsonite, which is an asphaltum of rare qualities recently discovcred in the United States, four ounces, on the Serial No. 283,430. (No sperimens.)
with a stirring or agitating device. I then i apply direct fire-heat to the whole, which will soon cause the gilsonite orgilsonite asphaltum to melt, and so soon as the heat has increased up to about 400 Fahrenheit the gilsonite will act as a peculiar solvent ofthe rubber. At or about this temperature I keep up a constant agitation of the mass, which will cause the indiarubbcr to go into a complete solution with the gilsonite. and while the mass is hot, I add (for ordinary purposes) about four and one-fourth ounces of manganated linseedoil. This manganated linseed-oil is made as follows: Take one gallon of raw Calcutta linseedoil and simmer same for about three hours,thcn gradually add about four ounces of the white borate of manganese and sti reonstantlyovera moderate fire for from six to eight hours, taking care not to exceed a heat that will turn a white feather, when dipped into the hot oil, a light-brown color, and afterward add about four onces of black oxide of manganese, and continue theheat for about one hour longer; then remove from the fire and allow the oil to cool and settle, after which it should be decanted clear for use. This mass of gilsonite asphaltum, vulcanized indiarubber, and manganated linseed-oil I then stir well over the tire for a few minutes and afterward remove from the fire and cool to about 200 Fahrenheit-,and add about three ounces of spirits of turpentine and about three ounces of deodorized petroleum naphtha of about 63 gravity. I then agitate the whole well and when quite cool add about halfan ounce (l oz.) of powdered sulphur and grind the whole mass in apaint or other mill. Thiscompletes the compound, which, as finished, is ofa thick pasty consistency and of a brownish-black color, but which will dry black. Articles may now be coated with the compound and dried, and if baked as a japan the compound will become vulcanized, or if allowed to dry without heat for a sufficient lengih of time the oil in the mass will bind the other ingredients and convert the compound into an excellent coating or covering for many purposes.
So soon as this takes place ingredients have been mixed and allowed to cool, as described, the powdered sulphur may be added before the turpentine and naphtha are introduced and when the mixture is at about 200 Fahrenheit. At this stage, if the heat is not increased, articles may be coated with or various material may be added to, the
I comp und and upon a suitable application of heat 1; e same may be vulcanized.
The compound may be reduced as required for use, either with turpentine or with naphtha and the quantities of such reducing materials be varied to suit the particular purpose.
if the compound is to be used as regular baking-japan, then the larger proportion of the mangan'ated linseed-oil panned in the formula here given should be used in the mixture;
but when the compound is required tobe other wise used, then the smaller proportion named in said formula of such oil will sufiice.
The following properties are embodied in this my new rubber eompound,orrubberite, as it may be termed. The india-rubber and gilsonite will resist most corrosive fluids to agreat extent, and will be found very durable when placed under ground. Furthermore, the manganated linseed-oil will prevent the india-rubher from being injured by the suns rays. The compound, it properly prepared by skillful workmen, compares favorably in many respects with india-rubber and gut-la pereha.
What I claim as new, and desire to secure by Letters Patent, is-
The within-described compound, composed of gilsonite asphaltum,vulcanized rubber,
(scrap or waste) manganatcd linseed-oil, spirits of turpentine, deodorized petroleum naphtha, and powdered sulphur, combined substantially as specified. V
