  • Quick change mounting bracket for loader arms
    Patent number: 3964622
    Abstract: A loading arm mounting bracket includes an upwardly open upper slot and a forwardly open lower slot respectively adapted to receive corresponding upper and lower pins of an implement bracket. A spring loaded lock plate is selectively received between the lower pin and slot-adjacent retaining plates, thereby removably securing the lower pin in the lower slot and trapping the upper pin in the upper slot. Manual release is obtained by pulling on a handle attached to the locking plate.
