  • Latch for a folding corn head
    Patent number: 5724798
    Abstract: A latch (48) for securing a pivotable portion (34) of a foldable corn head (10) to a fixed portion (32) thereof, the latch being actuated to close or open by the folding action of the corn head portions. In closing the latch, a slidable pin actuator (50) on one of the frame portions, which extends beyond the frame is engaged by the other frame portion. The motion of the pin rotates a crank (56) connected by a connecting link (64 to a rotatable overcenter catch (62) extending through a slot (69) in the other frame portion. The crank rotation causes the catch to rotate to engage and secure the other frame portion on its rear surface (70). Opening of the latch is the reverse of closing. Preferably, the lengths of the crank arms (58 & 60), connecting link, catch shaft (67), and the angles therebetween are selected such that the motion of the catch mimics in synchrony the motion of the pin.
