CHARLES JAMES BEAVER, OF HALE, ARTHUR FRANCIS WARD RICHARDS, OF IBROOKLANDS, AND ERNEST ALEXANDER CLAREMONT, OF HIGH LEGH,
SHEATH-COUPLING ELECTRIC CABLES.
To all whom it may concern fBe it known that-we, CHARLES JAMES certain new and useful Improvements in Sheath-Couplings for Electric Cables, of which the following is a specification.
This invention relates to the bridging of a subsidiary conductor across a joint in a cable in which such conductor surrounds the main conductor or conductors and is used for testing, detective and, or' protective purposes and it is desired to continue such subsidiary conductor over (while still enveloping) the joint and is a modification of the invention described in the specification filed on the application of us the said Charles James Beaver and Ernest Alexander Claremont No. 15821 of 1917.
This invention is useful in cases where avery high pressure is not used and it is not projecting points or partsin the joint and cases can be used alternatively to the thin metal conductor described in the said specification.
According to the present invention we form a sleeve composed of metal wire conductors (preferably individually insulated and preferably with hvgroscopic insulating materials) intertwine so as to form an open netting. Owing to the'open netting formation the sleeve can, within limits, be elongated or shortened with a corresponding contraction or ex ansion of its radius.
This sleeve is t readed on to one section of the cable and when the joint is made is placed in position over the joint, the ends of the wires com osing it bei bared of insulation and tie or otherwise astened by any convenient method to and may also be soldered to, the ends of the circular test conductor. With such a sleeve the desired bridgin of the joint can be readily and eflectua 1y made without interferin Wltll access to the joint of the main con uctors Specification of Letters Patent.
Patented July 1, 1919.
Application filed November 7, 1918. Serial No. 261,538.
for the purpose of enveloping the same with compound in the usual manner.
The accompanyin drawing which illustrates an example of our invention is a sectional plan of a joint between two sections of a three core cable in which a test conductor is embodied and bridged over the joint by a sleeve of metal wireentwined as above an open netting, and g and 9 show ring fittings (the former being shown in section) threaded over the main insulation and to which the test conductor is connected.
The bared ends of the wires comprising .the sleeve f are also connected to said rings 9' g and may be bound in position thereon by wire lappings and soldering as shown, or by any other suitable method-thus establishing electrical connection between the test conductors of the two sectionsrof cable and attaining the desired end of completely surrounding the main joint.
h designates the jointin sleeve containing the completed joint and plumbed to the lead sheathing of the cable as shown at iand i What we claim as. our invention and de sire to secure by Letters Patent of the United States is a 1. Inv a joint for sections of en electric cable containing a subsidiary conductor surrounding the main conductor or conductors and used for detective and/or protective-purposes the combination of a sleeve composed oi metal wire conductors intertwined to form an open netting threaded over the joint of the main conductor or conductors 'andelectrically joined to the sub metal wire conductors individually insuspecification in the presence of two Witnesses.
