ALDEN B. BLODGETT, OF LOWELL, MASSACHUSETTS, ASSIGNOR TO CHARLES H. MOEVOY, OF' SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 598,972, dated February 15, 1898.

Application filed December 22,1896. Serial No. 616,653. (No model.)

To all whom it may concern:

Be it known that I, ALDEN B. BLODGETT, a

citizen of the United States,residin g at Lowell,

and claimed, the object of the invention being to provide an inexpensive and effectual means of permanently securing the tip to the cover ing and to the core and thereby to hold the covering over the end of the core, and to prevent the tip from being drawn out of electrical contact with the core.

In the accompanying drawings, Figure 1 is a plan of a conducting-cord provided with my improvement, the end of the cord being represented as covered with a shell'or ferrule; Fig. 2, a central longitudinal section of the same on the line 2 2 in Fig. 1; Fig. 3, a plan of a part of a conducting-cord provided with my improved tip, the shell or ferrule being omitted and the fastening-wire being wound helicallyaround the end' of the conductingcord; Fig. 4, a central vertical cross-section on the line 4 4 in Fig. 3; Fig. 5, aplan of the tip-wire or needle enlarged.

The conducting-cord A consists of a core a, which may be of tinsel-covered thread or of a helically-wound wire covered with a tubular braided covering of textile material. The

core when made of tinsel-covered thread is usually braided into a tubular form to make a perfect electrical connection between all the threads of the core.

The tip-wire or needle B is rounded at b to enable it to be inserted with ease in the hollow core and to prevent its cutting the core when the same is made of tinsel-covered.

thread, and said tip-wire or needle B is provided with a transverse hole b to receive the fastening C, which may be of wire or thread, but is preferably of wire. The end I) of the needle B is inserted in the tubular core until the hole I) is well within the end of said core, and said needle is then secured in place by fastening a wire or thread through theouter covering and core and through said hole b. The wire fastening is then secured against displacement by bending the ends of said fastening which project beyond the covering toward the adjacent end of said covering, as shown in Fig. 2 at c c, or one end portion of said fastening may be so bent, as shown at c in Fig. 4, while the other projecting end portion of said fastening is wound helically about the covering and beyond the adjacent end thereof to the tip-wire, as shown at c in Figs. 3 and 4, and, if desired, the fasteningwire may be soldered to the tip-wire beyond the covering.

Where both ends of the fastening-wire are merely bent against the sides of the covering a, as shown at c c in Fig. 2, said ends and the I end of said covering are preferably covered by a shell or ferrule D, as shown in Fig.. 1, which fits the end of the conducting-cord proper and prevents the ends of the fastening-wire from being bent or displaced, the outer end of the shell fitting the tip-wire and,

if desired, being soldered or otherwise fastened thereto.

I claim as my invention- 1. An electric conductor, comprising a conducting-core, a non-conducting covering and a conducting-needle,having a transverse hole, and a fastening passed through said hole to retain said needle in said covering.

2. An electric conductor, comprisinga conducting-core, a non-conducting covering and a conducting-needle, having a transverse hole arranged within said covering, and a fastening passed through said covering and hole to retain said needle in said covering.

3. An electric conductor, comprising a conducting-core, a non-conducting covering and a conducting-needlajhaving a transverse hole arranged within said covering, and .a wire passed through said covering and hole,to retain said needle and wire in place.

4. An electric conductor, comprising a conducting-core, a non-conducting covering and a conducting-needle, having a transverse hole arranged within said covering,-and a wire passed through said covering and hole and needle and wire in place,andashel1,surr0und- 1o bent on the outside of said covering, to retain ing said needle and the end of said covering. said needle and wire in place. In Witness whereof I have signed this speci- 5. An electric conductor,'comprising a confication, in the presence of two attesting. wit ducting-core, a non-conducting covering and nesses, this 28th day of August, A. D. 1896.

a conducting-needle,havinga transversehole ALDEN B. BLODGETT. arranged within said covering, a-wire passed Witnesses:

through said covering and hole and bent on ALBERT M. MOORE,

the outside of said covering, to retain said I FRANK P. CHENEY.
