| 20110146114 | DIPPER DOOR LATCH WITH LOCKING MECHANISM - A dipper including a dipper door and an impact actuated jaw having a “C” shape 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. | 06-23-2011 |
| 20110038663 | METHOD OF ATTACHING TWO LARGE STRUCTURAL MEMBERS - A method of attaching a first structural member to a second structural member, the method comprising the steps of: attaching a plurality of spaced apart female pieces to the first structural member, pivotally attaching a plurality of spaced apart male pieces to the second structural member, the positions of the male pieces corresponding to the positions of the female pieces, inserting the male pieces into the female pieces, and connecting the male pieces and respective female pieces together. | 02-17-2011 |
