INSULATED CONDUCTOR.
SPECIFICATION forming part of Letters Patent No. 498,757, dated June 6, 1893. Application filed December 1,1892. Serial No. 453,718. (No specimens.)
To all whom it may concern.-
Be it known that I, THOMAS F. ATTIX, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Coverings for Insulated Electric Conductors, of which the following is a specification.
My invention relates to an improvement in coverings for insulated electric conductors in to which the conductor is provided with a fire and waterproof coating suitable for completely protecting the conductor from surrounding objects.
The particular object aimed at is to provide the conductor with a coating which shall completely protect it and which, at the same time, will permit of its being bent and twisted at sharp angles without injury to the coating and without in any respect impairing the insulation.
A practical embodiment of my invention is represented in the accompanying drawing, which represents an ordinary insulated electric wire provided with a double tubular coating of interwoven threads.
A represents an ordinary electric conductor provided with an insulating coat a, of guttapercha or other suitable insulating material such as is commonly employed in connection with the copper house-wires for incandescent electric lighting. Around the ordinary insulated conductor A, and in close proximity to its exterior, I lay the inner tubular section of my double tubular coating. This I prefer to 3 5 make as shown at B in the drawing, in which the coating is made of threads of cotton or other suitable fiber tightly braided about the exterior of the conductor A. This inner section B or B of the double tubular coating is then treated with a suitable waterproof material, such for example as what is commonly known in the art as the 13,15 waterproof paint, the treatment being preferably such as to thoroughlysaturate the coating. The waterproofed inner section of the double coating 5 is represented at b.
Upon the exterior of the inner section of the double coating and in close proximity to it, I form a tubular coating section G, preferably by braiding cotton threads, and this exterior section of the double coating I treat with a suitable fire proof material, such for example as what is known in the art as asbestus paint. Such treated exterior section is denoted at c. I prefer that the treatment of this exterior section should be suificient to thoroughly saturate the coating with the fireproof compound. After the insulated wire is provided with a double tubular coating, as hereinabove set fO1th,'it may be bent with 6c perfect freedom without impairing the protecting coat and may be laid with perfect freedom across or along in proximity to iron pipes, either hot or hold,.and in contact with moist or wet surfaces without in any wise interfering with the perfect insulation of the conductor and without danger of disturbing the integrity of the coating.
hat I claim is The combination with an insulated electric 7o conductor, of an inner tubular coating tightly braided about the exterior of the insulated conductor and treated with waterproof material and a second tubular coating tightly braided about the exterior of the inner tubular coating and treated with fire-proof material, substantially as set forth.
