Myinvention relatesto a` ste adying support for trolley concluctors and" has'particular' application to such' conductors as Suspended from the catenary ca'ble.

` The object otmy invention is to provide* a devce which willpreventside sway of the trolley concluctor, butat the same'time permit a vertical movement due to theupward pressur'e of thecurrent" collector. as it moves'a lon'g the trolley* wire and also' to permi t' a pivotal movement. of the clampj tor' supportng the troll'ey conrluct'or about a verticalaxssuch tha-t the trolTey clamp will have freedbmto move with the troll'ey wire' as it whips side' ways, thue relieving to a' large* degree Stress* 25 Figs. 3 and 4 and' 5 arer detailed views of the through or'clamping'bol't whi cli I emplby:

I have shown in Fig lmy inventon as` having one end Secured to a' support' 1" means of. a' fittngwhich in' turn' s` Secured' may have a proj ectng tongue 4 withahole therethrough to receive the pin" 5; I't will berecognizedhy those skuadra theart that in place of the support' 1 assh'own' the devicemay he attachecl to* other forms of' support common in overheadrailway Construction.

The troll'ey' conductor 6 is gripped by a; clamp 71 c'omprising'jaw'member 8 and &each proviclecljwith lips lOjto* grip' the conduct-,or 61 The jaweS and 9` have abutting members` 11 at one' endi The j aw's 8 and 9' are provided withtransverse' registeri ng h'oles between their upper' and l'oweredges' to receive the through bolt 1'2' shown` in cletail" in Figs. 3`, 4:' and. 5' and which comprises' a Stud portion' I with a threaded end 14 to receive the nut 15- and a socl' et portionl'having a passage 17 thereithrou'gh. When thethrough holti is posi- `tionccl relative to' the jaws' 8 and &and the'- to the support 1` bythe bolts' 31 Thefitting 2* nut1*5 d'rawr up, the jaws' will be forced into tight engagement with the' trolley conductor' 6)' and: the* abutting porti'ons 1'1 will also be forced into'` contact and" will act' a-s a fulcrum point for the jaws; If desired a spring lbck waslier 18 may' be' used'.

The "cl amp' 1 7" i s'supported by means of' the' steady rod 19" which is shown as. compri'sing a metal" member' 20 having a' bent' end por tion 21 which is` positionecf in the vertically clisposed passage?? in the' bolt 12 and. is prevented* froni vertical displacement by means oftheoverhanging lip'2`2` on the jew' 8. This Construction' will maintain' the clamp 7 and thesteady '1'od` 1 9? in' assembled' relation: such that the clamp will swivel in a; horizontal plane relative to the steady rod 19 and will move in a' vertical plane with the' member 1'9 a's the member 19 pivots: about the pin- 5'.

The rod" U'isshown' as secure'd to a strain insulator 23 which comprses an end ca'p 24` 'having' a cl'evis portion 25' Secured to the tongue 4 hy'means'of the pin 5 and also an end* cap 26 having' a' threaded portion 27 secured to the thre'a'ded end 28* of the rod 20. The end c aps 24* and 26' are connected by means' of the insulating` member' 29 which may be of wood or other suitable' insulating materiali The member 29" may have. tap'cring end portions upon which the Caps 24:. and 26 are compressed' or' the caps and end portions of the member 29 may he threadecl together or' they maybe Secured in other approved manner. In assemhling* the rod 20 to the. clamp 7 the bent en 21 is' positioned in* the'pas'- sage 17 before the member 12 is. position'ed with respect to the jaws. 8 and 9'.

'I prefer to have the longitudinal axis of the arm 19 angula r'ly disposed to the vertical plane common to the trol'ley wire holder 7 and the trolley' wire 6', thus giving: greater clearance' between the arm 1'9 and the outer end of a moving bow or pant'ograph current coll'ector;

Modifications of course will be apparent to those` shilled-` in the art', but I wish to be limited only by my" claims.

I claim 1. A steady'devce comprisinganelongated' me arm having means to secure one end of the arm to a support, holding means at the other end to hold a Wire, means on the holding means projecting sideways therefrom to slidably receive the end of the arm and projecting means on the holding means to engage the arm and prevent separation after assembly and in use.

2. A conductor support comprising means to receive and hold a conductor, transverse means secured to the' conductor-holding means to hold the jaws clamped to the conductor, transverse passage in the transverse holding means and having an aXis transverse to the conductor aXis and a support mounted in the passage to pivot about its aXis and projecting means on the conductor-holding means to co-operate with the support to prevent separation of the support and holding means after assembly of the parts.

3. A conductor support comprising clamping means to engage and hold a conductor comprising a pair of jaws, transverse means to hold the jaws clamped to the conductor, transverse passage in the transverse holding means and having an axis transverse to the conductor aXis and a support mounted in the passage to pivot about its aXis andmeans on one of the jaws to co-operate with the support to prevent separation of the support and clamping means after the parts are assembled.
