To all who-m it mcy concern: Y

Be it known tiret l, donn SODEN, s citizen of 'the .United Stores, residing at Ci icego, in xtloe county ot' Coolr end State ci illinois, lieve invented certein new and useful irnprovenients in High-Tension insulators, of which tbe following is s' specification.

Where conducting Wires or cables ore ern plo 'ed lor carrying currents of leigh poten (tie. greet drculty bos been experienced in proventiruT loss `ot current es by leelrsge more particular 7'due to wet surfaces during rainy or moist Weather, end where the insulators ere exposed" to sucli Weather conditions. This locke-ge taires place by erciug from tbe coblcs to some suppcrtin member and where c iilrn of moisture t es co materiel lossv of energy and destructive efiects ere manifest.'

The' objects of my invention ere, to prolvide ebigli tension insulstor adopted for conn ducting wires and cables, and involving effective resistance to puncture and surface erolog; to increase tlie surface resistance of tbe dielectric Inoteriel; to insure dryness of the surface resistance and thereby increase the resistance ego-inst surface srcing; to et,

` 'to involve simplicity of construction.

Tire contact or supporting insulutor being tbuslrepti'ree from tl ,c collection of moisture tliereon can lock reduced in superi'iciol aree, it being understood tliot in enses wlreretbe supporting insulator subject to g tire collection oi moisturettercon7 it be ege. 'Elie contact or supporting-insulator,

and tifo wire or 'cable et the point ci contact tlterewitli and to, a desirable extent at opper? site sides thereof are absolutely shielded from` Westl" er conditions suoli as rain und snomend the oir clisrnbcr ports'l ere also likewise protected. The body of air Within tbe chamber circulates through s space about tbe support ing insuletorend Wire or cable thereon con; tocting; ,tserevfith und adjacent thereto, and

e considerable Alength ofthe Wire or cable e25-` tending out from eacli side of tire chamber 1s also sl ielded from. such weather conditions ond t`^ereby kept dry.

The housing is without bottom and hence, air can circulate upwardly and thence pass out through the end openings 44. The guards or hood portions 42 protect the Openings 44 and also protect the wires, and a dry air chamber with an air space between the housinfr and the contact.

ln Figs. 5, 6 and 7, the gutter cover portion seats on sides 27 and 28 and can be secured iii'any suitable way, for example, by lugs 33a (dotted lines Fig. 7) having bolt holes t'oi bolts which attach tlieni to similar lug's 33h on the end portionsl of the base.
