Claim:
1. An assembly for mounting a longitudinally extending track on a substrate, the assembly comprising: a track plate having a top face adapted to carry the track and formed unitarily below the top face with a plurality of downwardly projecting tongues extending longitudinally parallel to the track; a base plate adapted to be anchored to the substrate, horizontally surrounding the tongues of the track plate, and formed with a plurality of upwardly projecting tongues extending longitudinally parallel to the track and transversely spaced from and horizontally interleaved with the tongues of the track plate, the track plate and base plate being wholly out of direct engagement with and spaced vertically or horizontally from each other; and an elastic jacket engaged between the plates and between the tongues of the track plate and the tongues of the base plate, whereby downward movement of the track plate relative to the substrate stresses the jacket in shear between the fingers.
