Abstract
An excavating tooth having a socket-equipped point mounted on an adapter nose and secured with a vertical pin on one side of the nose, the nose being grooved for receipt of the pin and equipped with a resilient keeper extending transversely of the point length, the point having a least one side wall extending rearwardly beyond the socket, the side wall having integral, vertically spaced apart lug portions having forwardly facing surfaces bearing against the pin, the nose groove providing a rearwardly facing surface bearing against the pin intermediate the lug bearing surfaces.
Claims12
A replacement point for an excavating tooth comprising relatively elongated, unitary body having an earth engaging edge at the forward end thereof and an adapter nose-receiving socket in the rear end defined by top, bottom and a pair of side walls, at least one of said side walls extending rearwardly beyond said top and bottom walls, each of said side walls which extend rearwardly beyond said top and bottom walls having adjacent the top and bottom thereof of vertically spaced upper and lower ear lugs aligned to receive a locking pin.
A replacement point for an excavating tooth comprising a relatively elongated, unitary body nose-receiving socket in the rearward end and defined by top, bottom and a pair of sidewalls, at least one of said sidewalls extending rearwardly beyond said top and bottom walls, each of said side walls which extend rearwardly beyond said top and bottom walls having adjacent the top and bottom thereof vertically spaced ear means aligned to bear against an elongated locking pin, each ear means including an integral lug projecting inwardly toward said socket from said side wall, each said lug having a forwardly facing bearing surface, aligned to enter into bearing relation with a locking pin.
A tooth point comprising a relatively elongated, unitary body having an earth engaging edge at the front end and being generally wedge-shaped to provide a rear end having an adapter nose-receiving socket projecting forwardly therefrom, said socket being defined by top, bottom and a pair of sidewalls, each of said sidewalls extending rearwardly beyond the rear and equipped with integral vertically spaced lug portions adjacent the top and bottom of said sidewall extensions, said lug portions extending inwardly at approximately a right angle to said socket and providing an interrupted generally arcuate, fowardly facing bearing surface for bearing against longitudinally spaced areas of a locking pin.
