Excavating tooth
First Claim
1. An excavating tooth comprising:
- an adapter having a rear base end for fixed engagement to a digging edge of an excavator, and a forwardly projecting nose;
a wear member having a longitudinal axis, a forward end and a rearwardly opening socket for receiving said nose of said adapter, said socket being defined by a pair of converging walls tapering toward said forward end, a pair of side walls, a plurality of first bearing faces extending substantially parallel to said longitudinal axis, and a plurality of second bearing faces extending substantially parallel to said longitudinal axis, said first bearing faces being spaced farther from said longitudinal axis than said second bearing faces, and each said first bearing face being located between one of said converging walls and one of said side walls; and
a lock for releasably securing said wear member to said adapter.

Abstract
An excavating tooth for attachment to the digging edge of excavating equipment includes a wear member provided with bearing faces in a socket which extend substantially parallel to the longitudinal axis of the tooth. The bearing faces are formed to widen significantly as they extend rearward to provide broad bearing surfaces at the rear ends of the wear member. The bearing faces are placed between the converging walls and the side walls of the socket at obtuse angles thereto to avoid areas of stress concentration. The bearing faces are further formed in a plurality of tiers to provide enhanced resistance to vertically applied loads at the front end of the member. The wear members are further secured to the adapter by locks which ease installation and removal of the wear members.

- 15. A wear member for an excavating tooth having a longitudinal axis, a forward end and a rearwardly opening socket for receiving a nose of an adapter, said socket being defined by a pair of converging walls tapering toward said forward end, a pair of side walls, a plurality of first bearing faces extending substantially parallel to said longitudinal axis, and a plurality of second bearing faces extending substantially parallel to said longitudinal axis, said first bearing faces being spaced farther from said longitudinal axis than said second bearing faces, and each said first bearing face being located between one of said converging walls and one of said side walls.
- 23. A wear member for an excavating tooth having a longitudinal axis, a forward end and a rearwardly opening socket for receiving a nose of an adapter, said socket being defined by a pair of converging walls, a pair of side walls, and a plurality of bearing faces extending substantially parallel to said longitudinal axis, each said bearing face extending between one of said converging walls and one of said side walls at obtuse angles thereto.
- 30. A wear member for an excavating moth having a longitudinal axis, a forward end and a rearwardly opening socket for receiving a nose of an adapter, said socket being defined by a top wall and a bottom wall converging toward said forward end, a pair of side walls, and a plurality of bearing faces extending substantially parallel to said longitudinal axis, each said bearing face having a front end and a rear end such that the rear end is substantially wider than said front end.
- 35. A wear member for an excavating tooth having top, bottom and side walls, a forward end and a rearwardly opening socket, said top and bottom walls converging in a forward direction to said forward end, one of said walls including a hole extending therethrough along a transverse axis for receiving a lock, said hole having a rear face and a front face, said rear face having a first segment converging toward said transverse axis when extending away from said socket and a second segment outward of said first segment extending substantially parallel to said transverse axis.
- 38. A wear member for an excavating tooth having top, bottom and side walls, a forward end and a rearwardly opening socket, said top and bottom walls converging in a forward direction to said forward end, one of said walls including a hole extending therethrough along a transverse axis for receiving a lock, said hole having a rear face forming a convex arcuated bearing face, and one face of said hole further including a keeper for releasably retaining a latch of the lock.
