Patent ID: 8449217

Claim:
A trench paver attachment for paving variable width trenches with asphalt, the attachment being connecting to the mounting plate assembly of a standard skid-steer loader and allowing paving of any trench from 18″ to 96″; the attachment comprising: a support assembly securable to mounting plate assembly carried by a skid-steer loader; right and left primary blades pivotally interconnected to the support assembly; right and left extensible and retractable hydraulic cylinders extending between spaced apart portions of the support assembly and the right and left primary blades respectively, the right and left cylinders being capable of moving the primary blades between a first position where they form an obtuse angle with each other and a second position where they form an acute angle with each other; means to support the primary blades so that the bottom of the primary blades are parallel to the surface of the adjacent roadway; right and left material scraper blades carried by the right and left primary blades, respectively, the width of the right and left material scraped blades being no more than the width of the trench to be paved; and means to adjustably mount the scraper blades on the primary blades so that the bottom edge of the scraper blades is either slightly above the surface of the adjacent roadway when the attachment is being used for paving the top layer of asphalt, or below the surface of the adjacent roadway and within the trench when the attachment is being used paving the base or binder layers of asphalt, or when being used for spreading backfill material within the trench.
