Abstract A front end loader includes a refuse storage body mounted on a supporting vehicle with the storage body having an upper opening for the deposit of refuse within the body. Closure members are movable between opened and closed positions adjacent the upper opening. The closure members shield the opening from the wind in their opened position and exert a downward packing force in moving from the opened to the closed position. The downward packing force is increased as the closure members approach the closed position. The free ends of the closure members provide a shearing action on the refuse overhanging the opening. Latching members latch the closure members to the storage body in the closed position of the closure member and move upwardly toward the opened position. The latching members may include first members on the storage body engageable with, and disengageable from, second members on the closure members. Windscreen members disposed adjacent the opening in the top of the storage body and biased toward the closed position are movable with the closure members between opened and closed positions. A cushion may be disposed between the closure members and the windscreen members in the closed positions of the closure members and the windscreen members.
In combination in a refuse loader, a refuse storage body having a roof and having an opening in the roof, a pair of doors movable to open and close the opening in the roof, means for supporting the doors on the opposite sides of the opening for pivotable movement between a horizontal position closing the opening and a vertical position exposing the opening, hydraulic means operatively coupled to the support means for providing a movement of the doors between the horizontal and vertical positions, means operatively coupled to the hydraulic means for providing a first positive force on the doors during the movement of the doors to the horizontal position to provide a packing into the storage body of refuse introduced into the storage body through the opening in the roof, and means operatively coupled to the hydraulic means for increasing, automatically and without manual intervention, the positive force on the doors to a greater force than the first positive force near the end of the movement of the doors to the horiziontal position to insure the packing into the storage body of the refuse introduced into the storage body through the opening in the roof.
