'l`he partiiznlur pnrpoe ol' in'v invention is to provide a eoi'ietrut'tion arrangement ot tithe wliith obviates illtN t|ll`lttl.l\)ll y liowii. the tube itl isilispowil between the upper rear poi-tion ot the lanip body and tht` upper end ol' the shunt; ot the hook. itsv lower entl :soldered to and eoiinnunitat'ing with the iiiteiioi oi: the. hotly. a at lOl". while it\l upper t-ntl ttl" extends well above i ol lered or other- \\i.t` stviii'eil to the hooli. by which it'` forms a lnaee between the liiinp and hook to stav and ti-engthen the. latter.
