Ground engaging tool tooth tip

Abstract

A tooth tip for a ground engaging tool has an elongate body disposed along a longitudinal axis extending from a relatively wide back surface to a relatively narrow front surface. The tooth tip may also have a cavity extending from the back surface towards the front surface and a bottom surface extending between the back surface and the front surface. The bottom surface may include a front face proximate the front surface and a back face proximate the back surface. The front face and the back face may be separated by a ridge. The tooth tip may also include a scallop positioned on the bottom surface extending from a first end proximate the ridge to a second end located towards the front surface.

1 . A tooth tip for a ground engaging tool, comprising:
 an elongate body disposed along a longitudinal axis extending from a relatively wide back surface to a relatively narrow front surface;   a cavity extending from the back surface towards the front surface;   a bottom surface extending between the back surface and the front surface, the bottom surface including a front face proximate the front surface and a back face proximate the back surface, the front face and the back face being separated by a ridge; and   a scallop positioned on the bottom surface extending from a first end proximate the ridge to a second end located towards the front surface.   
     
     
         2 . The tooth tip of  claim 1 , wherein the cavity extends from the back surface to a far end wall located proximate a shadow of the ridge. 
     
     
         3 . The tooth tip of  claim 1 , further including a riser on the bottom surface, the riser being a feature formed as a result of a casting operation used to fabricate the tooth tip. 
     
     
         4 . The tooth tip of  claim 3 , wherein the scallop has a substantially tear-drop shape. 
     
     
         5 . The tooth tip of  claim 4 , wherein a width and a depth of the scallop tapers from the first end to the second end. 
     
     
         6 . The tooth tip of  claim 5 , wherein the riser intersects the scallop proximate the second end such that the scallop and the riser share a surface at the second end. 
     
     
         7 . The tooth tip of  claim 3 , wherein the riser is positioned substantially within the scallop. 
     
     
         8 . The tooth tip of  claim 7 , wherein the riser projects upwardly from a bottom of the scallop. 
     
     
         9 . The tooth tip of  claim 1 , wherein the scallop has a flat base that is parallel to the longitudinal axis. 
     
     
         10 . The tooth tip of  claim 1 , wherein the tooth tip is configured to be removably coupled to a bucket of a machine at the cavity. 
     
     
         11 . A bucket for a machine, comprising:
 an adapter coupled to the bucket;   a tooth tip removably coupled to the adapter, the tooth tip including:
 an elongate body disposed along a longitudinal axis extending from a relatively wide back surface to a relatively narrow front surface; 
 a cavity extending from the back surface to a far end wall positioned towards the front surface, the cavity being configured to removably couple with the adapter; 
 a bottom surface extending between the back surface and the front surface, the bottom surface including a raised ridge region located proximately above the far end wall of the cavity, a front face extending from the ridge to the front surface, and a back face extending from the ridge to the back surface; and 
 a scallop positioned on the bottom surface, the scallop being an elongated depression extending along the longitudinal axis from a first end located on the ridge region to a second end positioned towards the front surface. 
   
     
     
         12 . The bucket of  claim 11 , wherein the tooth tip further includes a riser positioned on the front face, the riser being a feature formed as a result of a casting operation used to fabricate the tooth tip. 
     
     
         13 . The bucket of  claim 12 , wherein the riser intersects the scallop proximate the second end such that the scallop and the riser share a surface at the second end. 
     
     
         14 . The bucket of  claim 12 , wherein the riser is positioned substantially within the scallop. 
     
     
         15 . The bucket of  claim 11 , wherein the scallop has a substantially tear-drop shape, and a width and a depth of the scallop tapers from the first end to the second end. 
     
     
         16 . A tooth tip for a ground engaging tool, comprising:
 an elongate body extending along a longitudinal axis from a relatively wide back surface to a relatively narrow ground engaging front surface;   a cavity extending into the elongate body from the back surface to a far end wall positioned towards the front surface, the cavity being configured to removably couple with an adapter of the ground engaging tool; and   a scallop positioned on the far end wall, the scallop being a depression that extends into the elongate body by a depth of between about 5-30% of a depth of the cavity.   
     
     
         17 . The tooth tip of  claim 16 , wherein the scallop extends from the far end wall towards the front surface. 
     
     
         18 . The tooth tip of  claim 16 , wherein the scallop includes a plurality of scallops spaced apart from each other in a vertical direction. 
     
     
         19 . The tooth tip of  claim 16 , wherein the scallop includes a plurality of scallops spaced apart from each other in a horizontal direction. 
     
     
         20 . The tooth tip of  claim 16 , wherein the scallop includes a plurality of scallops, at least some scallops of the plurality of scallops being spaced apart from each other in a vertical direction and some scallops of the plurality of scallops being spaced apart from each other in a horizontal direction.
