  • Rod transfer mechanism synchronizer apparatus and method
    Patent number: 7562724
    Abstract: A synchronizer device is used for coordinating drill rod transfer mechanisms utilized in connection with transferring the drill rod between a drill rod magazine and the drill string in a horizontal directional drilling rig. The synchronizer device may transfer the movement from a first transfer mechanism to a second transfer mechanism, wherein the first transfer mechanism is powered and the apparatus acts as the motive force to move a second non-powered transfer mechanism. Alternatively, the synchronizer device may coordinate and synchronize the movement between a first and a second powered transfer mechanism. The synchronizer shaft is rotationally supported by bearings mounted on the rack frame of an HDD rig. The synchronizer shaft includes a longitudinal axis, a first end, and a second end. First and second ears are mounted on or proximate the first end and the second end of the synchronizer shaft respectively.
