WILLIAM GRISOOM, JR, OF BOUND BROOK, NEW JERSEY, ASSIGNOR TO THE STANDARD PAINT COMPANY, OF NEW YORK, N. Y.
METHOD OF COMPOUNDING VULCANIZABLE COMPOUNDS AND VULCANlZING AND APPLYING SAME.
SPECIFICATION forming part of Letters Patent No. 529,905, dated November 2'7, 1 894.
Application filed March 11,1891. fierial No. 384,645- (No specimens.)
izable compounds specially relates to a line of comparatively inexpensive vulcanizable, and vulcanized compounds, invented by me, and adapted for various uses, as substitutes in the same connections, for the more expen-' sive compounds, containing vegetable gums,
- such as caoutchouc or rubber.
So far as my knowledge extends, all vulcanizing methods heretofore practiced, involve the preliminary working of sulphur in its solid form, but finely powdered, into or with the mass of gum, and other constituents, and thereafter fusing the sulphur with the mass, during the process of vulcanization.
' A novel feature in my method, involves the preliminary melting of the sulphur, and then mixing. it with the other constituents, the latter then being also in a fused and more or less highly heated condition, and then developing the mass into a vulcanized condition, by the continued application of heat to a comparatively high degree.
In prior methods of combining vulcanized compounds to such fabrics, as cloth, or to other materials in permanent adherence, the vulcanizable compound, has always been first applied, and then the goods have been exposed to vulcanizable. conditions, as to time, and temperature. Another novel feature in my novel method, consists in first vulcanizing a mass of compound, and then while it is in a plastic condition, applying it to such goods or fabrics, as are to be charged, or coated therewith.
In my applications for patent, filed March 11, 1891, Serial Nos. 384,643 and 384,644, I have disclosed and claimed certain vulcaniz- 5o able compounds which may be and are, compounded, vulcanized and applied in a prac tical way in accordance with my present invention. For the purposes of this specification, it will be only necessary to state, that the prime elements in said compounds, are candle tar and sulphur.
' Although my present invention is not re stricted to any particular type of candle tar,
I deem it proper to state, that valuable and satisfactory results, will depend upon the use 'of the soft ropy candle tar, derived as a residual product from the distillation of animal fats and oils, as practiced by candle makers, and if other varieties of the residual products of candle makers stills are employed, they should be combined with the soft and ropy candle tar in various proportions, according to the uses to which the compound is to be applied; as for instance, if the intended use should call for specially durable flexibility, then more candle tar should be used than if the intended use required only water excluding capacities.
Whatever may be used with the. candle tar and sulphur, as additional plastic elements, are first mixed with the candle tar, under a temperature sufficiently high to secure a thoroughly liquefied condition of the mass, and then the sulphur in suitable proportions (say in weight from two to eight per cent. of the mass) is first melted and then mixed with the other ingredients, under a temperature of about 245 Fahrenheit, and then slowly raised to about 380 or 390 Fahrenheit. While the heat is thus being applied, the mass will foam 8 5 freely, during which mechanical agitation is desirable, and when the foaming ceases, and the mass has become practically quiescent, it will have been vulcanized, and is, in accordance with my invention, applied to any artio cles or materials to which the vulcanized material is to be permanently attached, as by charging textile goods, or paper, either to saturation or coating, or both, or to the surfaces of articles composed of non absorbent, or imperfectly absorbent materials, as with metal and wood.
Preparatory to the charging of heavy fibrous matter, with the vulcanized compound, it is sometimes desirable to dampen the fabric [00 with light oil of coal tar or other suitable solv ent of the compound, and as a rule solid bodies should be well warmed, prior to the application of the compound. The period of time within which the application of the vulcanized compound can be effected, is quite limited, seldom exceeding thirty minutes, the mass then rapidly losing its plasticity, even though the temperature be not materially lowered. Sheeted, or linear fabrics, such as cloth, paper, cord, &c., are passed rapidly through the plastic mass, well stripped as to excessive adherence, and as a rule, it will be desirable to dust them, as with powdered well dried soapstone, clay, or chalk, after which, and while still warm, the surfaces may be smoothly finished, as bythe use of cold rolls for the sheeted fabrics, and well rounded or tapered tubular dies for finishing the surfaces of cord, or other similar linear goods.
It is sometimes desirable, after compound ing the vulcanizable compound, in accordance with the first stated portion of my invention, to at once apply the compound to the articles to be permanently saturated or coated therewith, and to then subject the so treated goods toa vulcanizable temperature for vulcanizing or hardening the applied compound, and this mode of procedure constitutes another feature of my invention; and still another feature of that portion of my invention which relates to compounding and ap plying vnlcanizable compounds containing candle tar to fabricated materials, consists in the melting of the candletar, then mixing powdered sulphur therewith, then vulcanizing the mass, and then applying the same, while in a plastic condition, to fabricated ma- 'terials.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The method of compounding vulcanizable compounds containing such plastic matter as candle tar, which consists in heating the plasticmatter to a melted or well liquefied condition, and separately melting sulphur in appropriate quantity, and then combining and mixing the melted masses.
2. The method of compounding vulcanizable compounds containing such plastic matter as candle tar, and applying the same to various fabricated materials, which consists in first separately heating the plastic matter and sulphur to a melted or well liquefied condition, then combining and mixing the same, and then applying the compound in permanent adherence to the fabricated materials.
3. The method of compounding vulcanizable compounds, vulcanizing the same and applying them in permanent adherence to fabricated materials, which consists in separately melting the plastic elements, and the sulphur, to a well liquefied condition; then uniting and mixing the melted materials; then developing the same into a vulcanized condition, by appropriately subjecting the same to suitable temperature, and then after vulcanization, and while stillin a plastic condition, applying said compound to fabricated materials,'and in permanent adherence therewith.
