ABSTRACT:
Improvements in road-protecting devices for tracked vehicles which are removably secureable to individual elements of the tracks; heavy-duty road-protecting devices removably secureable to individual elements of endless tracks which permit the vehicle to be actually worked under heavy load without losing the removably secured road-protecting devices; Improved tensioning and connecting elements for such road-protecting devices, which, in the portions thereof vulnerable to heavy load or impacts, are largely or entirely located out of the load thrust lines of use, whereby the said devices may be formed or composed entirely of resilient, deformable rubber or plastic without requiring therewith base or cover plates or bolts or ties associated therewith; nonextensible elements of rigid or non-rigid character adapted to be received fully within the bodies of resilient road-protective devices which are inside of or incorporated within the load thrust lines of use, yet which are of such character as not to be vulnerable thereto or reduce the road-protecting capacities of the protective devices, said nonextensible elements cooperating with additional tensioning and connecting means located out of the stress and load thrust lines of use; improved resilient tensioning devices associated with such road-protecting devices which retain engagement on individual endless track elements despite temporary relief of tension on one or more thereof or collapsing of one or more thereof due to turning of or maneuvering of the tracked vehicle; such road-protecting elements, pads or devices having associated therewith nonextensible connecting elements extending therethrough being usable with extraordinarily powerful resilient springs or rigid engaging devices which may or may not be variably adjustable, in order to provide such road protecting devices usable with heavy duty working vehicles, not just for nonworking or unloaded travel on roads or the like.
