Abstract
A ground engaging tip of a tooth assembly for a base edge of a ground engaging implement, is provided, wherein the tooth assembly includes an adapter configured for attachment to a base edge of the ground engaging implement and having a forwardly extending adapter nose. The ground engaging tip may have a substantially keystone-shaped contour providing additional wear material at the top surface for use in top-wearing earth moving applications.

An adapter of a tooth assembly for a base edge of a ground engaging implement, the adapter comprising:
- a rearwardly extending top strap;
- a rearwardly extending bottom strap having a top surface, wherein the top strap and the bottom strap define a gap therebetween for receiving the base edge of the ground engaging implement;
- and
- a forward extending adapter nose comprising:
- a bottom surface extending forward relative to the top strap and the bottom strap,
- a front surface,
- a top surface,
- oppositely disposed side surfaces extending downwardly from the top surface to the bottom surface, wherein the side surfaces are tapered in a vertical direction such that a distance between the side surfaces decreases as the side surfaces extend downwardly from the top surface toward the bottom surface,
- wherein each of the side surfaces includes a projection extending outwardly therefrom.
A ground engaging tooth assembly for a base edge of a ground engaging implement, the ground engaging tooth assembly comprising:
- an adapter, comprising:
- a rearwardly extending top strap,
- a rearwardly extending bottom strap having a top surface, wherein the top strap and the bottom strap define a gap therebetween for receiving the base edge of the ground engaging implement, and
- a forward extending adapter nose, comprising:
- a bottom surface extending forward from the top strap and the bottom strap,
- a front surface,
- a top surface,
- oppositely disposed side surfaces extending downwardly from the top surface to the bottom surface, and
- a ground engaging tip, comprising:
- a rear edge,
- a top outer surface,
- a bottom outer surface, wherein the top outer surface and the bottom outer surface extend forward from the rear edge and converge at a front edge,
- oppositely disposed lateral outer surfaces extending downwardly from the top outer surface to the bottom outer surface, wherein the lateral outer surfaces are tapered so that a distance between the lateral outer surfaces decreases as the lateral outer surfaces extend downwardly from the top outer surface toward the bottom outer surface, and wherein each of the lateral outer surfaces includes a projecting portion extending outwardly therefrom, and an inner surface extending inwardly into the ground engaging tip from the rear edge and defining a nose cavity within the ground engaging tip having a complementary shape to the adapter nose of the adapter for receiving the adapter nose therein.
