ABSTRACT:
A belt transmission has a clutch that keeps both belts moving in the same direction when the transmission is in the forward mode and slackens only one of the belts during the usually brief interval that the transmission is placed in its reverse mode with the other belt moving in the reverse direction. Both belts share a common actuating lever having a lost motion coupling with one of the belts so that the lever can be placed in a neutral position in which neither of the belts is driven, even though power continues to be delivered to the transmission. The drive train that supplies such power accomplishes a substantially right-angle drive from the swingable tongue of the machine without a gear box by connecting a number of universal joints in a series that cuts across the corner between the swingable tongue and the main driven shaft of the transmission.
