  • Publication number: 20130269221
    Abstract: A tooth assembly for excavating equipment may include an adapter having first and second tapered surfaces and first and second sides, the first and second tapered surfaces defining an opening at a first end of the adapter. The tooth assembly may also include a tooth horn having first and second tapered surfaces, the adapter configured to be removably coupled to the tooth horn at the first end of the adapter, the first and second tapered surfaces of the tooth horn abutting the first and second surfaces of the adapter in a coupled position. The first side of the tooth horn may be adapted to receive a removable insert. A retaining pin may be configured to be removably fastened to the removable insert, the retaining pin removably securing the adapter to the tooth horn. The retaining pin may include a flexible reinforcement collar.

  • Patent number: 6799387
    Abstract: A removable adapter assembly includes a tapered body portion having a first end configured to receive a tooth horn, and a second end configured to receive a removable tooth. The tapered body may include first and second sides, which partially define a recess adjacent the first end. First and second interior surfaces of the first and second sides, respectively, have first and second gripping surfaces, respectively. The first and second gripping surfaces are configured to cooperate with a retractable insert that is coupled with the tooth horn. The tapered body is coupled with the tooth horn when the retractable insert is in a first extended position, and the tapered body may be removed from the tooth horn when the insert is in a second, retracted position.

  • Patent number: 5337495
    Abstract: A tooth assembly for mounting on the tooth horns of excavating or levelling apparatus buckets, shovels or alternative digging mechanisms. In a preferred embodiment the tooth assembly includes a wedge-shaped adapter for seating on a tooth horn, an insert removably seated in an insert cavity provided in each side of the adapter and a tooth point frontally engaging and bolted to the adapter by means of bolts threaded in the inserts, for engaging the material to be excavated. In another preferred embodiment top and bottom wear caps transversely slidably engage and bolt to the adapter adjacent to the tooth point for extending the life of the tooth assembly in the excavating or levelling operation.

  • Patent number: 5226249
    Abstract: A tightline apparatus for draglines which includes a pair of mechanical safety devices, each having an engaging bar pivotally attached to a swivel frame of the dragline above each drag rope at the point where the respective drag rope extends between each set of guide rollers. A limit switch is also mounted on each fairlead frame in close proximity to the corresponding engaging bar, such that movement of the drag ropes upwardly responsive to swinging of the dragline bucket past a predetermined point toward the boom causes the drag ropes to engage the engaging bar element of each tightline apparatus and pivot the engaging bar into contact with the limit switches, respectively, to terminate operation of the dragline bucket.
