INsULAiroR.

To all whom it may concern: l

Be it known that I, ANDREW J. SILEn, a citizen of the United States, lresiding at Massillon, in the county of Stark and State of Ohio, have invented certain new and usepassed around the insulator and bent aroundthe line wire, frequently doing great damage to the latter. A\tter years of practical cxperienee in this line of work, l have found that by the use of the tie wire, the main wire' is burned while wrapping it, causing it to become weak at that point which is the iirst place to break. lf the line is not wrapped tight with the tie wire, and the line wire breaks, it will run back practically one-halt mile, leaving a slack in the wire, and in Order to rc-adjust the wire, the tie wires from all the insulators for that distance must be removed to draw up the slack, and then be tied. This often happens after the wires have been up some tinie,and the tie wires have loosened up. lt might be further stated that when copper wire is used, the com anios prohibit the use of pliers in tying, the inexnen being required to use only their hands, in order to avoid getting it, too tight.

It is the iurposc ot' this invention to overcome this difficulty, as each span is held by itself by the aid of a-convcx curve inthe crown slot of the insulator, and the line wire is held against this curve by the pressure from beneath, that is, of the convex curve, and on top at each end of the curve by means of a lock wire.

`Vlith these objects in view, my invention consists in certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims. A In the accompanying drawings, Figure 1 is a View in ers ective, and Fig, 2 is a vertical longitu ina section.

y In the drawings, A, indicates the insulator-,the crown of which is enlarged and subdlvided into two parts 11, by the centrally located longitudinal groove 2, the bottom of which is convex, as shown in Fig.

2. The two partsof the crown extend, preferably, so as to overhang thsadjacent body portion of the insulator and the upper surfaces of which pjart preferably slope toward the ,central groove. The line wire 3 extends through the groove, and the ends of the groove are beneath the lower edge of the overhanging of the crown portion.

A lock wire 5 encircles the insulator just below the crown, and overlies the line wire at the ends or outlets of the groove, so that a double -pressure is' exerted upon the line wire, namely by the upward convex surface olt the bottom of the groove, and downwardly by the encircling lock wire, above 1the line wire at the two points where it extends outwardly from the ends of the groove. In thisway, the lock wire may be drawn as tight as possible, whether by hand or instrument.

A minimum amount of wire is required to form the locking wires, as they do not encircle the line wire, and at the same time, a definite location is provided for the locking wire, and furthermore, the combined etfect of the convex bottom and the two points of engagement of the locking wire upon the line wire makes a simple, secure, and etlectual fastening, which 1s easy to apply, and.

which prevents thc line wire from drawing through and becoming slack, while at the same time, preventing the burning out. alluded to hereinbefore.

vlt might further be mentioned that the insulator itself is of such aconstruetion that it may he easily cast of glass, (porcelain, or even rubber, and while the form illustrated is desirable, it is evident that it might be more or less changed in shape, and design. without departing from the spirit and scope of my invention; hence I do not wish to limit myself t the exact construction herein set. forth, butcl Having f ullylhescribed my invention, what `I claim as new and desire to secure by Letters Patent, is

1. An insulator made of a single piece of material comprising a body portion having a crown at one end which overhan s the body portion, and which is subdivide by a convex groove through the longitudinal center.

2. An insulator made of a single piece of material comprising a bodv portion having u crown at one end whi i overhangs the gkpoijionruid'whch is snbz'ivigied by a "voigiovethro'gh the longitudinal cen' @Kthe-np x' 'surfaces of the two parts ofd ollnjng downwardly to the groove. 5 3.1Tlqcom ination with an insulator havanfoverhanging subdivided crown at the inmune groove subdividng the crown being I,4| onvex, and a line wire passed in Contact l Jvfvith the convex groove, of a, lock wire encir- 0 olinggthe insulator immediately below the overhanging portion of the crown and hold- 1ng the ine wire at each end of tbe groove by engaging between the overhangmg portions of the crown and the line wire. y
