To all whom 'it may concern; A

Be it known that I, WALTER T. Goeman,

lof Victor, in the county of Ontario and, State of New York, have' invented certain new. anduseful Improvements in insulator- Protectors; and ILV-do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the. referencevnumerals marked thereon.V

v view.

'To these and other ends the invention con- -sists in certain improvements and combinaspecification.

In the drawings: Figure l'is a View of a part having an insulator'thereon provided with the improvements hereinclaimed; Fig. 2 is an enlarged View partly invertical section, and Fig?) is a transverse sectional ln the embodiment of the invention herein shown the insulator if supported horizontally, the support 1 in this instance being in the form of a cross piece secured to the post A.2. The insulator preferably comprises a plurality of sections, three of which 3, f1 and 5, may be ared and fitted one within another and closed` at their smaller ends which abut. The sections 3,4 and are se-` cured together in any suitable manner, but preferably by screw threads 6 and cement, the inner section 3 being secured to the support 1 and having its inner end arranged within the section 4, the outer section 5 havingl a' greater flare than the section 4, and thesection 4 having a greater flare than the section 3. The insulator also has a condl'c'tor supporting section in the form of a vertically ldisposed flange or` ring 7 which has such a diameter that the conductor is removed from the supportla distance to reduce the static strain to a minimum.

ring preferably has a grooved 'periphery to which the conductor 8 is secured in any suitable manner. In* the present .instance the conductor rests in the groove of the ring 7 and is secured to the insulator by two tie wires 10 and 11 looped around the ring in opposite sides of the latter and secured at their ends to the conductor as by split clamps 12. The foregoing construction is not claimed per se in this application as it forms thesubject matter of an application filed by me on June 12, 1908, Serial No. 438,056, for insulators, of which this is a division. f

1n order to prevent an arc formed between the insulator and its support destroying or cracking the insulator, I provide two arcing members 16 and 17, one connected to` the support, the other connected to the insulator, and both preferably projecting upwardly to a plane above the insulator. By projecting the arcing members above a horizontally arranged insulator the heat gener-v ated by the arc will cause the latter to rise rapidly and immediately away from the insulator and in this way minimize the liability of cracking or fusing of the insulator. The arcing members maybe mounted in any suitable manner, but it is preferred to have'them diverge upwardly relatively to each other so that the distance between they members increases as the arc weakens. Preferably, one of the members 17 carries a clamp 13 which is secured to the conductor 8 and tie wires 10 and 11 so as to be in direct connection with the conductor, while theother member is clamped to the support 1 vand has an extension 18 which projects in y WALTER T. dominan.- ilVitnesses z i AJenn S.
