H'l new and useful Improvements casino-Chains tor High-Pressure llrausinission-Lincs, which inn- 1' are fully forth in the followt ion, suspension method for aerial electric transinssion lines for any pressure has been proposeil, according to which any number ot' lines can he su 'iported by means of insuns composed either of insulating of llili consisting partly of insu- Cuannns Manna Repubor a porcelain. or a glass block provided two semi-circular cavities crossing one iron Wires being passed through ins, in such manner that the mateintly 'uniler cminn'ession. These then linked together and form n 'rupted chain.
the object of the-present application inrove this suspension chain, in order it. more especially suitable for the h 'h pressure electric transi. P accompanying drawings represent by Way of ea'anip'e the device forming the obq the present invention.
i are l a perspective View of a perinsulator. is. 9. is a vertical section two elements linked together. p and 5 are elevation views, on a smaller scale, shon-ing arious towns of :mistrueting the ispcnsion chain.
"The porcelain insulators A. (Fig. 1) coneach of a core a, perforated by two holes 7) and 7)", at right angles to each other and provided With integral Wings 0, o, of
' and thickness as to otlezsuit- ,ince tor the given pressure of the ion line, which the device has similar porcelain insulators A, A
a linked together by a ring B; a f iron wires passed through the hole i5 orcclain insulator Al, as Well as Franc through the hole 6 of the porcelain insulator A. i
The suspension chain or cable is formed by consecutively linking together in the above-described manner any desired numberor". the porcelain insulators according to the t'C('{U11'(.IllQNtS.
t will be noted that the Wings (1, (2 are formed by a single continuous curved flange which projects radially from the body of the link and extends around both ends of both openings. As a result of this arrangement, the link is made reversible and perfectly symmetrical in space. This flange reduces to a. minimum the possibility of the formation of short circuits; and, due to the peculiar inclined shape thereof, that portion of the flange adjacent one opening, such as Z) in Fig. 2, acts a water-shed to protect the ring. or band. ll which passes through the other opening I) of the link. These bands or rings are preferably made of flexible steel or iron Wire which is looped back and forth through the holes so as to form a cable of the necessary tensile strength.
Fig. shows the complete arrangement of a suspension chain. The transmission line C represented is for single-phase current, but it is quite evident that itniay be for two-phase or three-phase currents.
The elements oi the chain (Fig. 3) are all of the same dimensions, Whereas the chain shown. in Fig. 4 consists of porcelain insulators A, A of difierent dimensions which alternate.
construction as herein described, What I claim as my invention and desire to .secure by Letter Patent is in a prising a pair of saddles disposed at right angles to each other, each saddle having a siniilarly located opening therethrough, said openings adapted to receive loops for sesuspension insulator, a link com-
