COUPLING FOR UNDERGROUND WIRES.
SPECIFICATION forming part of Letters Patent No. 483,327, dated September 27', 1892.
Application filed February 16, 1892. fierial No. 421,740. (No model.)
To all whom it may concern: the other is provided with aleft-hand thread,
Be it known that 1, JOHN J. PURCELL, a and said sleeves, and so the wires, are concitizen of the United States, residing at lVashnected by a nut B, that is provided with right ington, in the District of Columbia, have inand left hand threads to engage the corre- 5 vented certain new and useful Improvements sponding threads of the sleeves. The purin Couplings for Underground Wires; and I pose of this double threading will be readily do declare the following to be a full, clear, and understood. As the nut is a conductor, the exact description of theinvention,suchas will wires of the two sections will thus be elccenable others skilled in the art to which it aptrically as well as mechanically connected to- 1o pertains to make and use the same, reference gether. To perfectly house this joint and being had to the accompanying drawings, and prevent the access of moisture to the wires, to the letters of reference marked thereon, I employ a sleeve or tube 0, whose internal which form a part of this specification. diameter is such as to cause it to snugly [it My invention relates to couplings for electhe lead-covered portion of the cable, but yet r 5 trio conductors, and more especially to that not so tightly but that said sleeve may readclass which are provided for affording access ily be slid along the cable. Said sleeve is to underground wires, which in the form of slipped over the end of one section and out a cable are inclosed by a covering of lead; of the way before the wires are coupled, as but,while designed especially for this particuabove described, and then after they are thus 2o lar form of conductor, it is to be understood coupled it is moved to a position over the that I do not limit myself to this use, but rejoint, so that a portion of its length will exgard myself as entitled to use it in connection tend over each section.
