Specification of Letters Patent.

Patented June 2, 1908. 906. Serial No. 322,533.

1 To all whom it may concern:

Be it known that I, FRANCIS B. H. PAINE, a citizen of the United States, and a resident I of Buffalo, New York, have invented certain new and useful Improvements in Supports l for Electrical Conductors, of which the following is a specification. l lllyinvention relates to the sup ort of, electrical transmission lines, especial y high tension lines, and is especially adapted for the support of these lines where they cross railroads or at any point where it would .be dangerous to have a line wire fall to theground or upon'buildings orlrolling stock; In these high tension lines there is little danger of any breakage ofthe line wire be tween the points of support, but there is danger that the line wire may break at. the insulator supporting it, due to the deteriorationof the wire caused by arcing, friction or other causes. By my invention I not only make sure that such a failure at the insulatf ing support .will not cause the line wire to fall tothe ground or upon buildings or rolling stock, but I immediately ground the line wire so that notice may be given to the staits connection with the ion of the defect, and so that the line wire is automatically disconnectedat the generating station as is usually done when a line wire becomes grounded. To this end I support the line wire in the ordinary manner from the usual insulator or insulators-and I also provide an auxiliary insulator or insulators con- I nected to the line wire in such a way that the wire will be positively supported upon failure I of the usual insulating support. I also provide a grounded contact arm that is in such a osition as to be put into connection with the ine' wire upon failure at the usual insulating l support. To effect this I rigidly attach to the line wire at a short distance away from short conductor or wire 'rnent with the grounded contact arm In this manner the line wire only falls a'short distance and is then positively held by th l connecting cableand the auxiliary insulator, eing groundedbecause of its contact with tion should the connection .between the short conductor and the auxiliary insulator fail. I thus support the line wire by the two insulators cooperatively and prevent its fallingto the ground if either insulator fails, while grounding it when either insulator fails. In this way it becomes impossible for the line wire to fall to the ground charged with its ordinary electro-motive force. Moreover, if there should be a break of the points of sup ort the falling of the wire would instant y cause it to become efiectively grounded.

Figure '1 of the drawings'accompanying this specification illustrates a single, line wire supported in accordance with my invention. Fig. 2 shows the same structure indicating the position of the grounded wire upon failure of either insulating support.

'A'represents the standard ortower porting the insulators and is, in this shown as a metallic framework.

supcase,

the tower A there is a railroad track or a road or building where it would be dangerousto permit the conductor C to fall. To prevent this I have provided a second insulator D, in

the present instance carried below, and to one side of the insulator B and independently] which is, in the present case, ametallic arm directly ed upon the tower A.

The auxiliary insulator D has been put into service and supports the entire weight of the 'line wire through the connection E. The line wire has fallen until the auxiliary insulator comes the insulator B, or

" obviously be varied greatly without depart- -G should be such as to insure contact between E and G when the wei ht of the line wire is thrown upon the auxi 'ary insulator while at the same time preserving suihcient normal distance betweenE and G to prevent the arc leapin across the ga If instead 0 the failure of the support at 'B, there should'be a failure of the support ati'D, the condition will then be that shown in dotted lines in Fig. 2. The conductor Chas not changed its position, but the failure of the support at D causes the short conductor E to fal loosely against the contact arm' and so ground it and the linewire to which it is attached, thus enabling the defect to be known at the power station so that it can be remedied before any further defect could occur. Preferably the rounding of the line wire, as above described, would be utilized to open a circuit breaker in thestation and thus render the line wire completely dead until the defect has been repaired.

I believe thatIhave shown in a general we the referable location of the insulators and the contact arm G, the line wire C and the conductor E but these locations may ing from the mode of operation of my invention.

While I have described my invention with special reference to the sup ort of the modern high tension transmission inc, it will be understood that it may be desirable to employ my invention for other electrical conductors that are to be supported adjacently to high tension transmission lines.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

1'. A high tension line conductor, two in ally connected to the conductor when it becomes disconnected from either of the insulators.'

2. In a high tension transmission line, two insulators suitably sup orted, a line wire connected to both of said insulators so as to be supported b either, and a contact formirig part of an e ectric circuit and arranged to -make engagement with the line wire when the support afforded by one of the insulators fails.

3. In'a high tension transmission line, two

insulators suitably supported, a line wire (ii 'iixed contact ihrmin that the line wire or attached conductor will move .when one of the insulating supports fails, and a contact in the line of said move- 'ment included in a circuit by contact with the conductor. or line wire.

4. In a high tension transmission line, a line wire, a contact forming part of an electric circuit, two insulators attached to said line wire and adapted to independently support the same in electrical connection with said contact but cooperatively maintaining plaid wire disconnected electrically there- 5. In a high tension transmission line, a

line wire, an insulating support therefor, an auxiliaryfinsulating support, a connecting conductor attached theretoand to the line wire, and a grounded contact in the line of movement of the line-wire or connecting conductor when one of the supports for the line wire fails.

6. In a high tension transmission line, a line wire, an insulating support therefor, an auxiliary insulatin support, a connecting conductor attache thereto and attached and electrically connected to the line wire, and a contact forming part of an electric circuit and in the line of movement of the line wire or connecting conductor whenone of the supports for the line wire fails.

7. The combination with the standard, the

insulator supported thereby and the line wire attached to the insulator, of an auxiliary insulating support carried by the ole,

a short conductor attached to the auxi iary insulating sup ort and to the line wire, and a part of an electric circuit and arm carried by the standard and extending underneath the short conductor and adapted to be engaged by the same when carrying the weight of the line wire because of the failure of the primary support for the line wire.

8 In ahigh tension transmission line, an insulator supporting the same in normal position, an auxiliary insulator, a short conductor attached to the line wire and the auxiliay insulator and adapted to support the line wire in a diiierentposition, and a fixed contact forming part of an electric circuit
