摘要： Apparatus for adjusting two butt-ends of rails to be connected by welding comprises a rigid structure having two aligned support plates one for each rail. Each support plate comprises a non-adjustable retaining press and an adjustable retaining press. The fixed jaws of one of each of the presses are intended to be placed on the side of the head of one of the rails and the fixed jaws of the other presses are intended to be placed on the corresponding side of the head of the other rail thus forming four spaced supports. The movable jaws of the presses for the one rail are intended to be placed on the opposite side of the head of this rail and the movable jaws of the presses for the other rail are intended to be placed on the opposite side of the head of the other rail.

摘要： A rigid power conductor to be suspended from an overhead structure or ceiling by means of insulators for the supply of electric energy to electric power driven vehicles on rails. The conductor is a conductor wire held between two side-by-side I-beams urged together so as to form a continuous clamp for the wire.The wire has lateral grooves whereas the I-beams define a conforming downwardly opening slot with projections engaging the grooves in the wire.The joints connecting the successive I-beams are longitudinally displaced, and an expansion joint is disclosed which permits relative displacement of the successive lengths of conductor.There is also disclosed an apparatus for the installation of the conductor wire and various devices for interconnecting the I-beams.
