Adjustable edge forming apparatus for paving machine

Abstract

An edge forming apparatus for a paving machine forms margins of road paving materials concomitantly with a paving operation. A tube member having a slidably engaged elongated member is included. Lock plates, having lock-plate openings, are positionably engaged with the elongated member. A shaping plate is adjustably coupled with the lock plates and includes offset strips, with apertures, fixedly attached thereto. An offset pin is selectively positioned in the lock plates and extends through the lock-plate openings and the apertures. The lock plates are positionably movable with the elongated member, positioning the shaping plate in one of a retracted position and an angled position. The shaping plate is restricted from substantial rotation through an engagement of the shaping plate with the tube member through a non-rotatable fit between the tube member and the elongated member in response to contact between the shaping plate and the road paving materials.

What is claimed is: 
     
         1 . An edge forming apparatus for a paving machine for forming margins of road paving materials concomitantly with a paving operation, the edge forming apparatus comprising:
 a tube member;   an elongated member slidably engaged with the tube member;   one or more lock plates in positionable engagement with the elongated member, the one or more lock plates having one or more lock-plate openings;   a shaping plate adjustably coupled with the one or more lock plates, the shaping plate including:
 one or more offset strips fixedly attached to the shaping plate, the one or more offset strips including one or more apertures; and 
   at least one offset pin for selectively positioning the one or more lock plates with the one or more offset strips by extension of the at least one offset pin through the one or more lock-plate openings in the one or more lock plates and the one or more apertures in the one or more offset strips, wherein
 the one or more lock plates being positionably movable with the elongated member to position the shaping plate in one of a retracted position and an angled position relative to the elongated member, wherein the shaping plate being restricted from substantial rotation through an engagement of the shaping plate with the tube member through a non-rotatable fit between the tube member and the elongated member in response to contact between the shaping plate and the road paving materials.
