Tip and adapter assembly

Abstract

A wear member for use with an adapter of an earthworking implement is provided. The wear member comprises a body having a pocket adapted to receive the adapter. The pocket has a mouth, a frontal portion, a top wall, a bottom wall, and a pair of side walls, and each top wall and bottom wall are conjoined to a respective side wall by a curvilinear corner each having a radius increasing in size from said frontal portion to the mouth.

What is claimed is:  
     
         1 . A wear member for use with an adapter of an earthworking implement, comprising: 
 a body having a pocket adapted to receive the adapter;    said pocket having a mouth, a frontal portion, a top wall, a bottom wall, and a pair of side walls; and    each said top wall and said bottom wall are conjoined to a respective side wall by a curvilinear corner each having a radius increasing in size from said frontal portion to said mouth.    
     
     
         2 . The wear member as set forth in  claim 1  wherein said pocket has a frontal portion having a frontal portion height that is between about 30 percent to about 75 percent of the frontal portion width.  
     
     
         3 . The wear member as set forth in  claim 2  wherein said frontal portion height is about 40 percent of the frontal portion width.  
     
     
         4 . The wear member as set forth in  claim 1  wherein said pocket has a pocket mouth having a pocket mouth height that is between about 75 percent to about 170 percent of a pocket mouth width.  
     
     
         5 . The wear member as set forth in  claim 4  wherein said pocket mouth height is about 110 percent of said pocket mouth width.  
     
     
         6 . The wear member as set forth in  claim 1  wherein said top wall and said bottom wall diverge away from each other from said frontal portion to said mouth at an included angle within a range of about 20 degrees to about 45 degrees.  
     
     
         7 . The wear member as set forth in  claim 6  wherein said angle is about 30 degrees.  
     
     
         8 . The wear member as set forth in  claim 1  wherein said side walls diverge away from each other from said frontal portion to said mouth at an included angle within a range of from about 0 degrees to about 45 degrees.  
     
     
         9 . The wear member as set forth in  claim 8  wherein said angle is about 4 degrees.  
     
     
         10 . The wear member as set forth in  claim 1  wherein said radii of each said curvilinear corner increases linearly from said frontal portion to said mouth.  
     
     
         11 . A wear member and adapter assembly, comprising: 
 an adapter having a rear mounting portion and having a nose portion, said nose portion having a nose frontal portion;    a wear member having a pocket sized to matingly engage said nose portion, said pocket further including a mouth and a frontal portion;    a retainer device adapted to detachably retain the wear member on the adapter; and    said engagement of said pocket and said nose portion defining a boundary having a plurality of curvilinear corners increasing in size from said nose frontal portion to said mouth.    
     
     
         12 . The wear member and adapter assembly as set forth in  claim 11  wherein 
 said wear member has a top surface and a bottom surface;  
 said adapter has a top wall structured and arranged to matingly engage said top surface thereby defining a boundary between said top wall and said top surface, and a bottom wall structured and arranged to matingly engage said bottom surface thereby defining a boundary between said bottom wall and said bottom surface; and  
 each said respective boundary diverging away from each other from said frontal nose portion to said rear nose portion at an included angle within a range of about 20 degrees to about 45 degrees.  
 
     
     
         13 . The wear member and adapted assembly as set forth in  claim 12  wherein said angle is about 30 degrees.  
     
     
         14 . The wear member and adapter assembly as set forth in  claim 11  wherein: 
 said wear member has a pair of side walls;  
 said adapter has a pair of side surfaces each structured and arranged to matingly engage a respective side wall thereby defining a respective boundary between a said side wall and a said side surface; and  
 each said respective boundary diverging away from each other from said frontal nose portion to said rear nose portion at an included angle within a range of about 0 degrees to about 45 degrees.  
 
     
     
         15 . The wear member and adapted assembly as set forth in  claim 14  wherein said angle is about 4 degrees.  
     
     
         16 . The wear member as set forth in  claim 11  wherein said radii of each said curvilinear corner increases linearly from said frontal portion to said mouth.  
     
     
         17 . A wear member for use with an adapter of an earthworking implement, comprising: 
 a body having a pocket adapted to receive the adapter;    said pocket having a mouth, a frontal portion, a top wall, a bottom wall, and a pair of side walls;    said top wall and said bottom wall diverge away from each other from said frontal portion to said mouth at an included angle within a range of about 20 degrees to about 45 degrees; and    said side walls diverge away from each other from said frontal portion to said mouth at an included angle within a range of from about 0 degrees to about 45 degrees.    
     
     
         18 . The wear member as set forth in  claim 17  wherein each said top wall and said bottom wall are conjoined to a respective side wall by a curvilinear corner each having a radius increasing in size from said frontal portion to said mouth.  
     
     
         19 . The wear member as set forth in  claim 18  wherein said radii of each said curvilinear corner increases linearly from said frontal portion to said mouth.
