' My invention relatesto high potential in- -sulators, and'more particularly to such ineulalors of Special-form are adapted to be mounted upon a wall, a floor, a roof or a partition, or adapted for use in connection with oil switches, and oil transformers, and in variouelanalogous relations.

My invention comprehends quite a number of separate-features ainong which are the' following: I. The provision of a tubular member for holdingr the Wire and'meaus .A specially adapted for supporting .this tubuylar member. II. To providea body portion moisture, this irregular `nnection with a central tubii ar niemberof @the kind Just meiitioned,re1silient members,

thereby performing the double ollice of preventing the entrance of Water or .moisture and o enabling comparatively -'brittle 'material such as glass, porcelain or the like to be em'iloyed to'rthe central' tubular inember. 'To so form and mount the various parte as'to enable a central tubular insulating member to be inade-o'brittle material and encircled by an Vinsulating body portion of comparatively tough and strong insulating material, preferably Electr-ose. VI. To provide a form 01E insulator in which the various parte or someI of them may be subjected to extremesbf heat and cold Without linipairing. the -yalue oftheiinSulatoi-.- V11.

vReference is to be had. to the accompanying drawing Jforming a partiot this specifi cation, inwhich the figure sliowsoiie form 'of iny insulator applied'in Athin instance to an Voil transformer, the lid or cap ol the latteriserving as a barrier for supporting the `insu1ator.` i f Alcesing .1 is provided at its top with ,a thickened portion,l and resting upon the latter-ipa lid 3 hereinafter called a barrier This barrier is held iii position on the easing l by nid of scicwbolle 4A andv may, tor various purposes Lie considered as the: equivalent or a root", a partition, a ceilingy or any forni of'bairier through which .a

conductor is t"o be, extended and upon ,which i' an insulator lieto-31e supported. il; quan; tlty` 'of oil 5 d )osedgwithin the easing i and serves the fs'ual purpoeef'oft-olxinan' 9 is integral with a head 10 which extends downwardly.` of insulating trose.

At 11 is'a removable bushing provided with a threaded portin12 and withl an annular flange 13, these parts being,r valso of lllectrose. The flange'. 13 is sunken slightly into the adjacent lowerend of the head a.

At 14 is a gasket of soft rubber, this gasrlhe parts just described are material, preferably Elecket having generally a frusto-conical form and beingr provided with an annular flange 15 extending outwardly.

A ring 16 of Electrose is threaded internally and is fitted upon the threaded portion 8. Two gaskets 17, 18 vare sunken into the lowermost surface of thering 16 and when this ring is screwed down upon the barrier 3, the gaskets 17, 18 are clamped tightly a ainst it. At 19, 20 are=siinilar gaskets w head 10.

A hood 21 serves asa cap piece`V and is mounted upon the upper portion 22l of the cylindrical member (5, this upper portion beyingthreaded for the purpose. The cap piece 21 1s provided with ail-annular sleeve 23 threaded internally for engaging the upper end of the cylindrical member 6. The ca) piece 2l is provided with a hood 24'extenfling downwardly and covering several of the corrugations. The cap piece21 is further provided with an annular portion 25 threaded internally, and titting into this is a busliing 26 threaded -cxternally' this .bushing havin anannular flange 27 which is sunken into tie annular portion 25. A gasket 28 similar in form to the gasket 14 is partially encircled by the bushingr 26 and is provided with .an annular flan e-29.

A wire 30 is provi ed' withl a'covering 3l' of insulatin material, the wireand its coverin extendi insulating material, preferably ofv porcelain. The middlev portion of this-tubular member `is provided with corru ations 33 -of annular form yextenda direct y around it. The tubular memberj32 1s provided with

cylindrical ends

34, 35, the' d end .9A-extenda upwardly thi-on piece 21, and t e end. wardly into the oil 5.

li the cap 35 extendigng down- .ing the spacing ich are sunken in the flange 9 andl ng throurh a central tubular mem er 32 which is 0 shocks, blows,

At 36 is a gasket which is provided with an annular portion 36a and is held in position by aid of the cap piece. Another gasket 37 similar to the one just described is mounted lower down within the head 10. These two gasketsv 36, 37 both encircle the central tubular member 32, at the top and bottom of an air passage 32a, and press in opposite directions against portions of saidtubular member. i y j At 38 is an annular air passage extending directly around the cylindrical',portion 35, this passage also extending fromthegasket 37 to the gasket l14. At 39 is a similar air passage extending from the gasket 36 to the gasket 29. f 4

At 40 is an annular air passage representof the inner edge ofthe barrier 3 from tlie SV of the cylindrical member 6'. Atetl is another annular-space just below the barrier 3 anddue to the 'fact that a portion of the flange S) is spaced slightl from this barrier.

The operation of my evice is as follows: The corrugations 33, by virtually increasing the external surface of th tubular member 32, tend to prevent surface leakage and destructive arcing. The tubular member 32 beingconcentrie to the cylindrical member 6 and spaced apart therefrom by the air'pas- Sugoi-i2, still further increases the insulation. No moisture can gety into the air passage 322" because of the gaskets, and"consequently the air passage last mentioned remains dry. Moreover, the external, surface of the .fylindrir-al men-roer 6 is kept dry by aid of the hood 24. The annular air passage `fl() improvesI the Iinsulation'. The an' passi'ige t1 between the flange 0 and the barrier 3 4")i'evcnts leakage bctween these parts. Adjacent to the gaskets 36,' 37 the air passages 3S. 39 afford protection from the current, and the gaskets 14, 28V together with the bushings 11. 26 tend to still further improve the insulation. v i

The various gaskets employed, beea'usepf their resiliency, tend to prevent breakag of Vthe parts which this manner porcelain tube and also to use tively -wide range of insulat-in v constructing eachv and all o the various parts. The gaskets 14, 28', 36fand 37, by neatly 'fittin Aaround the central tube, and also by ren ering the latter -watcrtightenable this ftubetfbe made of 'comparatively great, length; and also enable a comparamaterials in und. other forms of concussion v-hienmight otherwise tend-to break'it.

g Moreover, the-strains due to expansion and contraction from heat and rcold ered in every sense harmless becauseof the action of -these various gaskets. Again, the annular and cylindrical' air chambers disposed within tjhe insulator and bounded byv outer surface of the portion action of the various happen to be brittle and inv enable inc to use the central,
