WILLIAM R. SEIGLE, 9F NASHUA, NEW HAMPSHIRE.
PROCESS OF FORMTNG INSULATING-TUBES.
Specification of letters Patent.
Applicationfiled December 20, 1909. Serial No. 534,185.
Patented Jan. 10, 1911.
To all whom it may concern:
Beit known that I, VILLIAM R. SEIGLE,
a citizen of the United States, and resident of Nashua, in the county of Hillsboro and State of New Hampshire, have invented new and useful Improvements in Processes of I Formin InsulatingTubes, of which the following is a specification.
c My invention relates to the art of formin tubes of electrically-'nsulating material and consists in a new process by which effective insulating tubes may be formed.
In the drawing hereto annexed there is illustrated a tube in process of formation according to my new process.
I, take a sheet of fibrous material, preferably refractory material, such as a.sheet 'of asbestos cloth'or paper, and first wind the same in a close spiral'upon a suitable core or mandrel, first, hdwever, applying to the surface of the fibrous sheet a coating of finely divided liquefiable hydrocarbon. The hydrocarbons which I believe are suited to this purpose are the harder pitches or asphalts, and the asphalt material known as gilsonite, is, I believe, better 'suitedto the formation of insulating tubes according to i ,this method than any'other substance. If
desired, the fibrous sheet A may be prepared by coatin it'with an adhesive, before the finely div ded hydocarbon is dusted over its surface, so that the act of rolling up the spiral will have less effect to disturb the distribution of the hydrocarbon. WVhen the sheet A is wound into a close spiral upon the mandrel B, the hydrocarbon particles 0 will be quite uniformly distributed throughout the entire body of the tube thus formed. I next heat the tube to a degree sufficient to liquefy the hydrocarbon particle's distributed therethrough and their liquefaction results in a general impregnation of the fibrolfs body which is more or less complete according to the proportion of comminuted hydro carbon originally provided.
In its preferred form the insulating tube is constructed by rolling'a spiral, 1n the mannen described, of asbestos paper which has been-previously liberally sprinkled with powdered gilsonite. Thesubsequent heating of the asbestos tube brings about a very thorough distribution of the gilsonite body.
throughout the mass, and this is enhanced and the effect improved if the heating is applied by immersing the entire tube in a body of similar material, preferably liquid gilsonite, heated to a high temperature. The gilsonite particles included inthe body of the tube facilitate the saturation of the tube by additional liquefied hydrocarbon entering from without and the effect is one of internal expansion inthe body of the tube which compacts all parts of it very closely, so that after the tube has cooled, a section thereof hardly discloses the original laminated structure. Tubes of this kind may be made with walls as thick or as thin as desired, their insulating property and dielectric strength are both extremely high and they constitute suitable conduits for electric wires intended to carry currents of high tension.
What I claim and desire to secure by Letters Patent is:
1. The method of forming tubes which consists in distributing-finely divided lique fiable hydrocarbon over a flexible sheet of fibrous material, rolling the sheet into a tubular spiral inclosing the hydrocarbon between its layers, and thereafter heating the tubular body thus formed, liquefying and further distributing the hydrocarbon in the fibrous mass. '2. The method of forming tubes whicl consists in distributing finely divided liquelfiable hydrocarbon over a sheet of asbestos material, rolling the sheet into a tubular spiral inclosing the hydrocarbon between its layers and thereafter immersing the tubular body in a liquefied hydrocarbon at a temperature sufficiently high'to liquefy the hydrocarbon originally contained in the tubular 3. The method of forming tubes which consists in distributing finely divided liquefiable hydrocarbon over a sheet of asbestos fiber, rolling the sheet into a tubular spiral, inclosing the hydrocarbon between its layers, and thereafter heating the tubular body,
liquefying and further distributing the hyv drocarbon in the mass.
4. The method of forming tubes, which consists in distributing finely divided liquefiable hydrocarbon over a sheet of asbestos fiber, rolling the sheet into a tubular spiral Signed by me at Boston, Massachusetts inclosing the hydrocarbon between its lziythis tenth day of December 1909. ers, and thereafter immersing the tubu ar. body in a liquefied hydrocarbon which is VILLIAM SEIGLE' Witnesses:
5 solid at ordinary tem erature, liquefying the hydrocarbon origina 1y distributed through CHARLES D. WoonBERRY, the tubular body. JOSEPHINE H. RYAN.
