ABSTRACT:
An apparatus for packing material in an open top container. The first ends of first and second arm members are pivotally attached to a support member. The opposite ends of a link member are pivotally attached, respectively, to the first and second arm members at points between the opposite ends of the first and second arm members. The upper end of a leg portion of a packer member is pivotally attached to the second ends of the first and second arm members. A foot portion is attached the lower end of the leg portion of the packer member. Urging structure, such as a hydraulic cylinder, causes the first arm member to pivot about the pivotal connection between the first end of the first arm member and the support member so that the second end of the first and second arm members will move through an arc, the link member will move through an arc, the leg portion of the packer member will move through an arc, and the foot portion of the packer member will move substantially vertically.
