Tamping Tool

Abstract

The present invention includes a tamping tool having a main shaft body with an end portion having a tongue section and a tamping pad having a groove for receiving and engaging the tongue section. The tamping pad preferably includes an abrasive material along a tamping edge. A weld bead is used to secure the tongue section with the groove.

1 . A tamping tool comprising: 
 an integrally formed main shaft having at one end a tongue section; and    a tamping pad having a groove configured to receive and engage the tongue section, the tamping pad having a lower tamping edge and wherein at least the lower tamping edge is made of an abrasive material.    
     
     
         2 . The tamping tool of  claim 1  wherein the tongue section is of a dovetail configuration and the groove is of a configuration to receive the dovetail configured tongue section.  
     
     
         3 . The tamping tool of  claim 1  wherein the abrasive material is a nickel chromium alloy.  
     
     
         4 . The tamping tool of  claim 1  wherein the abrasive material comprises tungsten carbide, chrome carbide or tantalum carbide.  
     
     
         5 . The tamping tool of  claim 1  wherein the tongue section is retained within the groove by a weld.  
     
     
         6 . The tamping tool of  claim 5  wherein the weld is a 312 alloy.  
     
     
         7 . A method of attaching a tamping pad to a tamping tool comprising: 
 providing a shaft having at one end a tongue section;    providing a tamping pad having a groove configured to receive and engage the tongue section;    engaging the groove by sliding the tongue section within the groove; and    retaining the tongue section within the groove.    
     
     
         8 . The method of  claim 8  and further including providing a weld bead.  
     
     
         9 . The method of  claim 8  and wherein the weld is a 312 alloy.
