Snow blower with edge blades

Abstract

The combination of a snow blower and edge blades. The snow blower of the type having an auger housing which includes a back wall, a planar left vertical wall and a planar right vertical wall wherein the walls defining the housing of the auger. The planar left vertical wall includes a left forward edge and the planar right vertical wall includes a right forward edge. There is an edge blade affixed to each outer side of the vertical walls proximate the forward edges; wherein the edge blades include a cutting face with a leading edge spaced form the vertical wall thereby creating a snow gap between the vertical walls and a snow removal edge.

1 ) A combination of a snow blower and edge blades comprising:
 a) A snow blower of the type having an auger housing which includes a back wall, a planar left vertical wall and a planar right vertical wall, the walls defining the housing of the auger,   b) wherein the planar left vertical wall includes a left forward edge and the planar right vertical wall includes a right forward edge;   c) an edge blade affixed to each outer side of the vertical walls proximate the forward edges;   d) wherein the edge blades include a cutting face with a leading edge spaced form the vertical wall thereby creating a snow gap between the vertical walls and a snow removal edge.   
   
   
       2 ) The combination claimed in  claim 1  wherein the edge blade includes a mounting face dimensioned for mounting the edge blade to the vertical walls. 
   
   
       3 ) The combination claimed in  claim 1  wherein the cutting face includes a serrated leading edge. 
   
   
       4 ) The combination claimed in  claim 1  wherein the edge blade raked backwardly at an angle theta relative to the vertical such that the bottom of the blade contacting the snow prior to the top of the blade. 
   
   
       5 ) The combination claimed in  claim 2  wherein the edge blade includes a transition face connecting the cutting face with the mounting face. 
   
   
       6 ) The combination claimed in  claim 5  wherein the transition face being perpendicular to the mounting face. 
   
   
       7 ) The combination claimed in  claim 5  wherein the transition face being perpendicular to the cutting face. 
   
   
       8 ) The combination claimed in  claim 1  wherein the mounting face is parallel to the cutting face. 
   
   
       9 ) The combination claimed in  claim 5  wherein the edge blade including a first and second L shaped strip wherein the strips are connected at the transition face. 
   
   
       10 ) The combination claimed in  claim 1  wherein the edge blades extending vertically higher than the right and left vertical walls.
