    Abstract: Apparatus for continuously feeding objects from the top of tiered loads includes in a preferred embodiment a hoist pivotable at its base to receive a first tiered load and then hoist the load upwardly along an angular load path. Extendable skids are mounted along the angular path for relative movement toward the load as it is hoisted, the skids being adapted continuously to engage the load and feed tiers from its ends. Supporting accumulator forks disposed along the path are insertable therein to receive the load from the hoist so as to maintain the load's engagement with the skids as the hoist retracts and pivots to receive a second load. Once all the tiers have been removed from the forks, they retract from the load path and the second load is hoisted to engage the skids. In a second embodiment, the hoist receives the first load and hoists it vertically. A raking mechanism rests on the load and engages it to rake successive tiers from the load.
