Abstract (en)
[origin: US4320708A] A device for adjusting two butt ends of rails to be connected by welding comprises a rigid structure which is formed by two support plates. The support plates are aligned and interconnected by a concave part and which is able to be disposed horizontally so that the two support plates are pressed one against one vertical side of the head of one of the rails and the other against the corresponding vertical side of the head of the other rail. The concave part provides a region for access around the butt ends. Each support plate is provided with a retaining clamp which is provided with a jaw able to bear against the opposite vertical side of the head of the rail. The device can be applied to the welding of rails on a track or on a fixed installation.
