ABSTRACT:
Apparatus for dumping the contents of a container, for example, a drum, includes a first frame for receiving tines of a fork lift, a second frame for receiving a drum pivotally mounted on the first frame and a latch secured to the second frame. The latch is held by a normally extended spring in a first position latching the first frame and the second frame together. The latch includes a latch pin which extends downward below the bottom of the drum when the drum is raised from the ground for emptying. The raised drum is moved forward into position so that the latch pin engages an upper edge of a receptacle for receiving contents of the drum. As the raised drum is moved further forward with the latch pin still engaging the upper edge of the receptacle, the latch moves into a second position compressing the spring and releasing the second frame from latched engagement with the first frame. This allows the drum to pivot on the first frame to an inverted position for emptying. The inverted drum is moved rearward until its open edge strikes the upper edge of the receptacle and the drum is rotated thereabout until it regains an upright latched position. A method for using the apparatus is also described.
