0. N. WAITE. INSULATED CONDUCTOR.
Patented Jan. 9, 1894.
UNITED STATES PATENT O FICE.
CHARLES N. WAITE, OF NEWTON, MASSACHUSETTS.
' INSULATED CONDUCTOR.
SPECIFICATION forming part of Letters Patent No. 512,417, dated. January 9, 1894. Application filed February 20, 1893. Serial No. 463, 7 model-l To all whom it may concern:
Be it known that I, CHARLES N. WAITE, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Insulated Oonductors, of which the following is a specification, reference being bad therein to the accompanying drawing.
In the manufacture of chlorine by the electrolysis of alkaline chlorides, the chlorine is conducted from the cells preferably by means of lead pipes. I have found it desirable to insulate these lead gas conductors electrically.
My invention has for its object to provide a proper insulation for such gas conductors and it consists of means for that purpose as hereinafter described and the novel features of which are pointed out in the claims which are appended hereto and made a part hereof.
In the accom panyingdrawing, I have shown my device in the best form now known to me, and in the following specification I will refer to said drawing in which Ihave shown a section of two parts of a lead pipe or gas conductor which are connected, and which are insulated at the joint by the employment of my device.
Referring to the drawing, P P are sections of the lead gas conductor. The part P is provided with a cup-shaped enlargement b which is designed to receive the end of the other section of the gas conductor P, as also the insulating material.
a is a ring or wicking of asbestus, which is interposed between the end of the section P and the cup-shaped enlargement 12. Above the asbestus ring is a mass of Trinidad asphalt d, or other similarv material, which is not affected by the chlorine, and which serves to seal the joint. The ring of asbestus serves to hold the melted pitch or asphalt d after it has been placed within the cup b and around the end of the section P of the gas conductor, until the pitch has had time to cool and harden. It will be noted that the end of the section P of the leaden gas conductor projects downwardly below the asbestus ring. This is for the purpose of preventing any con densed vapor from coming in contact with the asbestus insulation and thereby forming an electrical connection between the two sections of the conductor.
It will be obvious that the size and shape of the conductor may be varied as desired.
What I claim is- 1. Agas conductor consisting of two or more sections, the end of one of the sections being enlarged to receive the proximate end of the other section, and having within the enlargement a ring or layer of asbestus anda mass of asphalt, or similar substance, which will seal the joint, said asbestus and asphalt being interposed between the proximate portions of the sections of the conductor, substantially as and for the purposes set forth.
2. A metallic gas conductor consisting of two or more sections, one of said sections being enlarged at the end to receive the end of the other section and having within the enlargement a layer of insulating material interposed between the proximate portions of the sections, substantially as and for the purposes set forth.
3. A metallic gas conductor consisting of two or more sections, one end of said sections being enlarged at the end to receive the end of the other section, and a mass of insulating material and of sealing material interposed within the said enlarged end between the proximate portions of the said sections whereby the same are insulated and the joint sealed, substantially as set forth.
4. A metallic gas conductor composed of two or more sections, one of said sections having an enlarged end to receive the end of the other section, and a layer of insulating ma terial interposed between the proximate portions of the endsof said sections, the end of that section which is received within the enlarged end of the other section extending past the insulating material whereby condensed vapor is prevented from collecting on the insulating material, substantially as set forth.
In testimony whereof I affix my signatur in presence of two witnesses.
. CHARLES N. WAITE. Witnesses:
WM. A. MAoLEoD, ROBERT WALLACE.
