Curb shoe assembly for shoulder grading

Abstract

A curb shoe assembly for street grading and curb formation is provided. The curb shoe assembly includes a channel member having a front side, a back side, a bottom side and a central trough sized for receiving the bottom edge of a construction vehicle mow blade. The curb shoe further includes a grading blade which extends downward from the bottom side of the channel member. The grading blade includes a laterally extending portion and an angled portion. The angled portion includes a vertically extending edge for confronting a curb shoulder. Preferably, the angled portion is removable for replacement due to damage. The curb shoe includes a pair of straps for affixing the curb shoe's channel member to a mow blade. In addition, the curb shoe assembly includes a shoe having a horizontally extending plate. The horizontally extending plate is positioned adjacent to the grading blade so as to rest upon a street curb during operation. The shoe includes vertically extending rods sized and positioned to slidably extend into collars affixed to the front and rear sides of the channel member. Since the shoe can be moved upwardly or downwardly, the height of the grading blade's vertically extending edge can be adjusted for the formation of curbs of different heights. The curb shoe assembly includes one or more shoe spacers insertable and removable between the channel member's bottom side and the shoe's planar plate for maintaining the shoe in proper position.

1 . A curb shoe assembly for a mow blade comprising:
 a channel member having a front side, a rear side, a bottom side and a central trough sized and configured for receipt of the bottom corner of a mow blade, said channel member further including a pair of collars each having a central opening with a first collar affixed to the exterior surface of said channel front side and a second collar affixed to the exterior surface of said channel back side, said collars aligned to extend substantially vertically;   a grading blade extending downward from said channel member's bottom side and having a lower surface adapted to confront a road surface and a vertically extending edge for confronting a shoulder area;   a plurality of straps of adjustable length sized and configured to extend from said channel front side over the top edge a mow blade to said channel member back side for affixing the curb shoe to a mow blade without requiring holes formed in the surface of mow blade;   a shoe including a substantially horizontally extending planar plate positioned below said channel member bottom side adjacent to said grading blade, said shoe further including a pair of vertically extending rods slidably positioned within said channel member collars; and   one of more shoe spacers insertable and removable between said channel member's bottom side and said shoe's planar plate for adjusting the distance between said channel member bottom side and said shoe for correspondingly adjusting the length of said channel member edge confronting a shoulder area.   
   
   
       2 . The curb shoe assembly for a mow blade of  claim 1  wherein said grading blade includes laterally extending portion and an angled portion, said angled portion including said blade edge for confronting a shoulder area, said angled portion further being attachable and detachable to said laterally extending portion for permitting replacement of said angled portion in the event of wear or damage.
