Apparatus and method for applying a foam layer to cover and seal dumped waste
First Claim
1. Apparatus for the spraying of hardenable plastic foam for the covering and sealing of dumped waste comprising a compacting wheel, said compacting wheel adapted to be tracked over dumped waste, said compacting wheel wider than the tracks of a tractor vehicle adapted to track said wheel, hardenable foam generating means, yoke means, a plurality of nozzles extending from said yoke means, said foam generating means and yoke means and said nozzles adapted to track with said wheel, said nozzles alternatingly extending downwardly on said yoke means at an angle away from a vertical plane and juxtaposed to said compacting wheel, said hardenable plastic foam generating means adapted to deliver said foam at high velocity to said nozzles to adhere to said waste, and said nozzles adapted to spray a swath at least the width of said compacting wheel over waste computed by said wheel.

Abstract
An apparatus and method for covering and sealing dumped waste is provided wherein hardenable plastic foam is sprayed in a swath as waste is compacted by a roller. The roller is wider than the treads of the tractor vehicle, the spray nozzles are angulated alternately, spraying any projection. The configuration of the wheel and nozzles reduced gaps in the foam layer by a large factor over the prior art using less foam and labor and in less time.
