摘要

An articulated framework for an agricultural haymaker has two members able to swing at least twenty-five degrees relative to each other with two parallel swing axes in one plane, and comprising two cog segments (5) in mesh. It has a universal knuckle joint with a double cross core (11) for transmitting torque, and frame members are connected to it by flanges (6). The sides of the joint (7) have geared ends (8) in mesh with each other and the centres of these ends have the same cover. USE/ADVANTAGE - A frame member can swing at least an angle of one hundred degrees up or down to the horizontal.
