ABSTRACT:
A portable uncoupling device comprising a raised resilient strap attached to a self locating base and used to uncouple miniature railroad cars where the two couplers connecting two railroad cars each have one lift pin located on opposite sides of the centerline running between the rails of a miniature railroad track. The raised resilient strap is secured at one end to the self locating base, the other end of the strap touching the base but being able to slide freely along it so as not to buckle as the raised straps is depressed. The base has crimped ends to secure it between two railroad ties and sufficient width to allow it to fit snugly between the rails. The resilient strap has a width slightly greater than half the width of the base and is positioned so that it lifts only one lift pin of two connected couplers and provides support below the center of mass of the railroad cars passing over it. The strap is curved on the end where it touches the base so that it can slide freely as it flexes up and down under the weight of the miniature railroad cars passing over it. Notches in the sides of the base permit the uncoupler to be installed in curved sections of track as well as straight ones.
