28 which is part of the Welded copper coat ofv the steel that the plug is made from. The conductor 26 is placed in the sleeve 29 whichv isprovided with the bell mouth at `3l! and the conductor is brazed in the sleeve Where it occupies the channel of the plug to` complete the solid stock of the plug so that it spreads uniformly against the conical end of the; hole. `The cross section of the plug is much greater than the cross-section of the channel. This enables the plugtobe drivenwith considerabl'eforce against the conical 'end of the rail hole Withoutdeform- 'Ihe sleeve is..bent,at a rightfanglek Withthe conductor as it.. leavesrthe rail. hole and.v the channellof'the plug 22`-` is curved as indicated at 3l to corre--V spondwith theloerid` offthesleeve but provided Withsuiicient clearance to enable the plugto bedriveninto place.k This construction presents -a solidhead oftheplug`v for driving.A purposes.
kThe channel of the plug24, Fig. 4, has open sides` asindicatedat` 34to; permit the conductor.. 26 toenterr the channeh In order to close thechanneland toprovide a perfect cylinder for the plug beforeit is'driven in therail hole it is re-formed-in the separable dies32 and 33 which pressftheplug into-cylindrical'forrn and which may, be madesornewhat oversize to provide for thisoperation. The ,atnosed plugin Fig.y 1-is madefrom steel vilfithawelded copper' coat and is, expanded, in' thev railhole by drivingv on its onterend. The copper coating makes a: yielding surface. thatformsl-,a better seal With the Walls of therail hole than is obtained by a plug of .steel alone, thecopper alsol forms a large nonru'sting contact area.' between the plug and thev rails. 'lhe action of a cylindrical plugthat is expandedin`v thev rail -hole isvnot the samejas `a. taperedpin drivenl into acylindricalhole inthe rail., Inpractice thepinmust be softer than thestockof the rail so .that the excess thickness of the tapered 'pini is shorn oiT as it is `driven into the hole, withoutmaterially tightening-the connection. by expanding thepin in the hole.
A tapered type of channel pin does not expand in the rail hole by the driving action to bind the conductor in the channelin the manner obtained by this invention. V-
The construction shown provides an attachment between a stranded conductor and a'rail made from achannel shaped,rflat nosed plug with fj *A the conductor in the channel Vand the plug eX- panded in a bottomed hole in the railand variations thereof may be made without `'departing from the invention.
