Abstract
Abstract A positioner for objects such as car couplers undergoing repair welding which includes a vertically movable carriage, a longitudinal shaft and bearing supported on the carriage, the longitudinal bearing being adjustable angularly with respect to the carriage, a lateral bearing supported on the longitudinal bearing, a shaft journaled in the lateral bearing, the lateral bearing shaft being angularly adjustable with respect to the lateral bearing, and a clamp for the object mounted on the lateral bearing shaft. The clamp preferably includes scissors arms and a device to apply clamping pressure on the scissors arms. The scissors arms desirably are provided with pivoted jaws to engage the object. A safety bar extending from the lateral bearing shaft is desirably placed beneath the object.
