20120237283 | COMPACT QUICK COUPLING MECHANISM FOR TOOL ATTACHMENT - A compact quick coupling apparatus has a wedge movable between closed and open positions. A wedge spring extends in the opening direction from the wedge and urges the wedge in the closing direction. A latch spring urges a safety latch to a latched position to prevent the wedge from moving. A single acting hydraulic cylinder extends through the wedge and extends in the opening direction from the wedge. As the hydraulic cylinder extends it first moves the safety latch to the unlatched position, and then moves the wedge in the opening direction. When pressurized fluid is released from the hydraulic cylinder, it retracts and the wedge moves in the closing in response to the wedge spring until the wedge reaches the closed position, and then the hydraulic cylinder further retracts in response to the latch spring and the safety latch moves to the latched position. | 09-20-2012 |
20110290621 | AGRICULTURAL EQUIPMENT DRIVE SYSTEM - An agricultural equipment drive system comprises a main drive shaft connectable to a power source, a first gear box, a second gear box and a second drive shaft. The first gear box has a first gear box input connected to the main drive shaft and a first gear box output at a first angle to the first gear box input. The second gear box has a second gear box input connected to the first gear box output and a second gear box output at a second angle to the second gear box input. The second drive shaft connects the first gear box output to the second gear box input. | 12-01-2011 |
20090218198 | CONVEYOR BELT GUIDE - A belt guide apparatus for attachment to a belt conveyor comprises top and bottom plates. Walls extend between the top and bottom plates. The plates and walls form a belt envelope that defines a belt opening that substantially corresponds to a cross-section of the endless belt such that the endless belt can slide freely through the belt opening yet is substantially prevented from moving laterally or vertically. A front entrance of the belt envelope is configured to funnel the endless belt into the belt opening, and when attached to the belt conveyor the belt envelope is oriented such that the right and left walls are aligned with a desired path of the endless belt, and the endless belt passes through the belt opening. | 09-03-2009 |
20080296031 | Quick Coupling Mechanism for Tool Attachment - A quick coupling apparatus for coupling a tool to a tool arm comprises a coupler member attached to the tool arm, and configured to engage a mounting bracket extending out from the tool. A wedge is mounted on the coupler member and is movable, when the coupler member and mounting bracket are engaged, from a closed position engaged in a groove on the mounting bracket to an open position where the wedge is removed from the groove. A wedge positioning mechanism selectively moves the wedge to the closed position and the open position. When the wedge moves into the groove and into the closed position, a remotely operated latch control moves a safety latch from an unlatched position to a latched position to prevent the wedge from moving toward the open position. The wedge positioning mechanism can be configured to utilize a single or double acting actuator. | 12-04-2008 |
