CV drive shaft construction

Year	Description
1996	Invention patented by Estle A. Cook and Loretta E. Cook on October 10th, 1996. Abstract: A shaft construction transmits power from a vehicle to a driven mechanism located on an implement. The shaft construction includes a first shaft having a first end coupled to the driving shaft of the vehicle. A second end of the first shaft is coupled to a first end of a second shaft by a first universal joint. A second end of the second shaft is coupled to a driven shaft of the implement by a second universal joint. A positioning structure includes a first frame disposed adjacent the first universal joint and a second frame disposed adjacent the second universal joint. The first shaft is rotatably coupled to the positioning structure so that it is maintained substantially perpendicular to the first frame in the horizontal plane. The first and second frame members are connected by a pair of elongated links. Each of the links is pivotally secured at opposite ends to each of the frames. The links cross one another as they extend between the frames. This positioning structure maintains the angle between the first and second shafts substantially equal to the angle between the second shaft and the driven shaft of the implement in the horizontal plane.
