The invention comprises a scraper assembly, and a method of forming same, for mounting forwardly of a padfoot-type, earth-compactor drum for scraping earth, mud and clay accretion from between rows of the padfeet, as well as for scraping the same from the faces of the padfeet, and in an embodiment thereof, the assembly comprises an array of longitudinally disposed and parallel rows of teeth arranged with diverging angles therebetween for efficiently cleaning the padfeet in both rotatable directions of the drum. The teeth are secured firmly to an I-beam which extends across the front of the drum, and a mounting assembly, for a fluid-pressure cylinder, is fixed to the I-beam to control a dozer blade.

In the embodiment shown, the assembly comprises a pair of apertured weights mounted on a rotatable shaft, each of the weights having abutment surfaces one or another pairs of which close upon each other, depending upon the direction of shaft rotation. One of the weights is keyed to the shaft to rotate therewith; the other weight is freely rotatable relative to the shaft. Upon rotation of the shaft in a first direction, a first pair of the abutment surfaces engage, and the eccentricities of the weights then are so disposed as to produce a given-amplitude vibratory force. Upon rotation of the shaft in a contrary direction, a second pair of the abutment surfaces engage, and the eccentricities of the weights then are so disposed as to produce a vibratory force of a differing amplitude.

In a preferred embodiment of the invention a pair of shock plates are disposed in parallel, and substantially bi-planar, coupled together by elastomeric elements. One of the shock plates has a cut-out therein and the other has a limb extending into the cut-out and spaced apart from the sides thereof. The one shock plate is mounted to the drum bearing housing of the earth compactor, and the other shock plate is mounted to the frame. Accordingly, upon the drum being vibrated, or shocked, or otherwise displaced, the limb engages one or more sides of the cut-out, and the movement between the plates is thereby limited to a given distance, in order that the elastomeric coupling will not be unduly stretched, destroyed, or fatigued too early.
