Abstract From the Canadian patent

A cleat assembly for the endless track of a vehicle which effectively reduces loosening of the cleat upon the flexible belt of the track, comprising a grouser plate incorporating projections distributed thereover and a backing plate on the other side of the belt also having beltward projections, said projections being clamped by mounting bolts to press into the surface of the flexible belt to provide, shearing area to resist the belt load upon the grouser. The mounting holes through the belt are prevented from elongating and the cleat assembly is held firmly in position even after extended use and plastic flow of the material of the belt.
