Improvements in road-protecting devices for tracked vehicles removably securable to the individual elements of the tracks; road protecting devices having resilient tensioning devices associated therewith operable to strongly retain such on the tracks even when the track elements are aggregate loaded; improved tensioning and connecting means for road protecting devices which are largely located out of the load thrust lines of use whereby the devices may be entirely of resilient deformable rubber without basing or cover plates or bolts or ties associated therewith; high capacity tension devices of resilient character received within the bodies of resilient protective devices at least in part with track connecting means located out of the thrust line; improved track engaging means (connecting devices) which retain engagement on individual track elements despite temporary relief of tension thereon due to turning of the tracked vehicle.

Track and road protecting means for use with individual track elements of an endless tracked vehicle, successive track elements of said endless track having a transverse cleat on the outboard surface thereof adjacent one end thereof, comprising, in combination: a resilient, flexible, deformable yet

Track and road protecting means for use with individual track elements of an endless tracked vehicle, successive track elements of said endless track having a transverse cleat on the outboard surface thereof adjacent one end thereof, comprising, in combination: a resilient, flexible, deformable yet shape-retaining block under load adapted to fit on the outboard face of a single track element of an endless track and positioned thereon, said block substantially rectangular in plan, side and end views and having substantially rectangular, paired and parallel side faces, end faces and inboard and outboard load bearing faces, the length of said block a substantial part of the distance from cleat to cleat of successive track elements, the height of the block substantially greater than the cleat height from the clean outboard surface of the track element, and the width of the block at least a substantial part of the width of the track, means for connecting the block to the opposite side edges of an individual track element positioned laterally of each of the side faces of said block, and resilient tensioning means engaging the block with the inboard portion thereof and the connecting means with the outboard portions thereof, said tensioning means including a coil spring.
