ABSTRACT:
An apparatus for continuously feeding the individual elements from tiered loads has a hoist including both vertical and horizontal support members which can both be pivoted back to come in contact with an accumulator arm assembly by the motion of a rotatable support base thereby allowing the load to be raised upwards along an angular load path. The accumulator arm assembly includes a carriage assembly which can slide part of the way down the load path and independently extendible accumulator arms for extending beneath the bottom of the tiered load once approximately one-half of the load has been unloaded down the load-discharging members to the fixed and predeterminable load discharging point where it can be processed on a conventional feed table. After the accumulator arms have been extended and have begun to raise the remainder of the load along the last portion of the load path, the hoise is free to return to its initial position and accept a second load of material. In an alternate embodiment, the hoist is omitted thereby providing an accumulator arm assembly which can be retro-fitted into, and used in conjunction with existing hoists.
