    Abstract: A dipper assembly includes a body defining an outer surface and an opening, a door pivotably coupled to the body, and a latch mechanism releasably securing the door relative to the body. The door is pivotable between a closed position in which the door is positioned adjacent the opening and an open position in which the door is positioned away from the opening. The latch mechanism includes a latchkeeper and a latch member engaging the latchkeeper. The latch member is coupled to one of the body and the door and the latchkeeper is coupled to the other of the body and the door. The latchkeeper includes an end surface and a stop member coupled to the end surface. The stop member engages the one of the body and the door when the door is in the closed position. The stop member is extendable relative to the end surface.

    Abstract: A dipper including a dipper door and an impact actuated jaw defining a lip and a chin The jaw is rotatably mounted on the dipper door for rotation between a door-opened position and a door-closed position and positioned so that when the jaw is in the door-opened position, the jaw chin can be impacted by the dipper body when the door pivots to the door-closed position. The dipper also includes a hold open mechanism for releasably holding the door latch in the latch open position when the latch is in the open position, and a locking mechanism for releasably locking the latch when the latch is in the door-closed position. The locking mechanism includes one bar pivotally attached to the door, and another bar pivotally connected to and extending between each of the one bar and the latch.
