:No. 842,942. Specification of Application filed January 29 To aZZ whom it may concern.-

Be it known that I, WA TER G; GLARK, of the city, county, and State of New York, have invented a new and useful Improvement in VVire-Insulators, ofwhich the following is a full, clear, and exact description.

' My invention relates to improvements in insulators such as are used for supporting and insulating electric'wires I The invention is especially intended for use in connectionwith insulators and with I Wire-clamps which are fastened to the-wire clamps are and fit againstthe'insulator,sothat no tying is necessary and in such a way that when the adjusted the wires are held in place by their own'tension and are also held view, partly in side elevation and the wires shall be held rigidly I wires can have a. certain freedom of movedescribed and the novel and 2 is a plan view, artly in horizontal section,

securely against the insulator. In carrying out this idea I produce in the sides of the insulators sockets which are opposite but may be continuous or annular and which are constructed so that the'walls, and especially the upper Walls,of the sockets engage the clamps and prevent their displacement. In con sonance with this idea the sockets and the retaining-clamps can be constructed so that or so that the m'ent laterally, if preferred. The arrangement, it will be noticed from the description which follows, is such as to permit the Wires to be stretched with great facility and nicety without any tying means except that of the clamps and at the same time the wires are securely. held to the insulators, which latter may, in a general way, be of any usual or referred type;

With't iese ends in ,VieW my invention consists of an im roved insulator and the com-. bination of the insulator and wire-clan1p, which arrangement will be hereinafter fully features claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

.Figure 1 is a view, partly in side elevation and partly in vertical section, of an insulator clamps, showing my improvement. Fig.

of the structure s Fig. 3 is a partly in vertical section, of an insulator, showing a slightly-modified form of the invention; and Fig. 4 is a side elevation of the insulator own in Fig. 1.

' patented Feb. 5, 1907.

The insulator 10 may be of the usual orof any preferred construction, and I have shown an ordinary petticoat type of insulator which is provided with a wire-groove 11 across the top, this being common to insulators of this yp 12, and the wire is provided with-clamps 13, which can be of any approved kind, but which, as shown, have their inner-ends beveled, 'so as to fit in the sockets 14 of the insulator, which sockets are placed diametrically opposite and coincident with the ends of the groove 11, the sockets having their upper walls beveled, as shown at 15, so as to fit snugly and flatly against the corresponding beveled ends of the clamps 13. If desired, the insulator 10- can have the usual annular groove around the top but I have not shown it in Fig. 1, and it will also be understood that the socket 14 can be annular-that is, can becarried entirely around the insulator; but I prefer for certain purposes to use it as shown in Figs. 1 and 2, where the two sockets are placed diametrically opposite and in line with the groove 1 1. When this arrangement is used, the wire is stretched through the groove 11, and the clamps 13 are put in position upon the wire, forced up snugly into the sockets 14, and fastened. Thus it will be seen the wire is securely held in place, and it is also rigidly held, as the ends of fit snugly in the sockets. r

In Figs. 3 and 4 I have sho'wn a construction which is similar in principle to that set out above, but which is intended to provide a greater freedom of action for to permit them to have a greater swaying movement, and in some places this is desirablei As here shown, the insulator 10, which, as above stated, can be of any form, has the wiregroove 11 and has alsothe sockl ets on the sides and nearthe top; but, as shown, the sockets are in the form of concave I recesses 16, which are adapted to receive the ends of the-clamps 13*. These clamps have I ball-like end portions and can be otherwise of any approved kind; but as the ends fit closely in the recesses 16 they form,'in effect, and in combination with the insulator, ball joints, I which permit the wires 12 to sway freely in any direction, but without straining the insulator. The clamps 15 can be provided with loops 13 on the side,- which. shouldaline with the wire-groove 17 near the top of the insulator, and tie-wires can be passed through the clamps The groove is to receive the line-wire the wires, so as clamps can be correspondingly changed, but

to relieve thestrain from the wires 12 and limit the movement of the clamps 13..

I From the foregoing description it will be readily understood that the form of opposed" sockets on the insulator can be changed in many ways and that the form of the wire-- that the essential thing is to have opposed sockets or-recesses on the insulator, which will serve to hold'the wire-clamps, and con sequently the wires, in place and which will permit the wire to span the top of the insula I-thereforedo not limit myself to any particular form of socket, insulator, or c amp, ut claim, broadly, the combination of insulator, wire, and clamp which will permit the arrangement described to be carried 1 out.

In practice it is desirable to have thes'ockthe wire 12' will run straight through the clamps and through the groove 11 p but obviously. the sockets might be a little lower without affecting the principle of the inventionto compensate for sagvof wire'in span; I v

Having thus fully described m invention, 1 claim as new and desire to secure by Letters Patent* 1. The combination with an insulator havstructed to receive a wire, and; having ets on its outer sides, of clamps constructed clamps-adapted to be secured to a wire and engage the insulator beneath the said overhang.

3.- An insulator having a top grooveand sockets in the outer sides, at the ends of and in. alin'ement with thegroove.

i 4. The combination, with an insulator having peripheral overhanging or projecting edges, of ball-like clamps to engage a wire and fit beneath the said overhang.

5. The combination with an insulator having a' grooved top and ball-sockets at the ends of the grooves, and onthe outer sides of the insulator, of ball-like wire-clamps to en-' gage a wire and fit in the aforesaid sockets.
