Excavating tooth and adapter

Abstract

An excavating tooth has an adapter, a point and a locking device. The adapter has a forwardly protruding nose, a channel and a body. The body of the adapter is configured to be secured to excavating equipment. The point has a rearwardly opening socket for receiving the adapter nose therein, a forward digging member, and an ear extending from a side wall of the point, the ear having a recess. The locking device has a rigid body and a depressible protrusion. The rigid body is configured for receipt in the channel of the point and the depressible protrusion is configured for receipt in the recess of the adapter. The protrusion resiliently engages the recess for tightening the point to the adapter. The nose of the adapter has a plurality of tongues and the socket of the point has a plurality of grooves for receiving the plurality of tongues.

1 . An excavating tooth comprising: 
 an adapter comprising a forwardly protruding nose, a channel and a body, the body configured to be secured to excavating equipment;    a point comprising a rearwardly opening socket for receiving the nose therein, a forward digging member, and an ear extending from a side wall of the point, the ear having a recess;    a locking device comprising a rigid body and a depressible protrusion, the rigid body configured for receipt in the channel, the depressible protrusion configured for receipt in the recess;    whereby the protrusion resiliently engages the recess for tightening the point to the adapter.    
     
     
         2 . An excavating tooth as in  claim 1  wherein the nose is configured in a general cone shape.  
     
     
         3 . An excavating tooth as in  claim 2  wherein the nose of the adapter comprises a plurality of tongues and the socket of the point comprises a plurality of grooves for receiving the plurality of tongues.  
     
     
         4 . An excavating tooth as in  claim 2  wherein a front portion of the nose of the adapter comprises a front stabilizer and a rear portion of the socket comprises a stablizer receiving depression for receiving the front stabilizer.  
     
     
         5 . An excavating tooth as in  claim 3  wherein the plurality of tongues are configured in a rearwardly spiraling formation about the nose of the adapter.  
     
     
         6 . An excavating tooth as in  claim 4  wherein stablizer gussets are coupled to the front stabilizer, the gussets configured in a rearwardly spiraling formation about the nose of the adapter.  
     
     
         7 . An excavating tooth as in  claim 3  wherein the plurality of tongues is three tongues.  
     
     
         8 . An excavating tooth as in  claim 1  wherein the channel is located on a body of the adapter.
