Claim Text:
1. Apparatus for insulating a building by unrolling bulk rolls of insulation in vertical strips on a wall or frame of the building from an upper attachment extreme on the building wall or frame down to a vertically-spaced away lower attachment extreme thereon and across multiple rows of vertically spaced intermediate attachment positions on the building wall or frame, each bulk roll of insulation comprising a stiff cylindrical hollow core that is axially elongated between opposite ends and a longitudinally elongated strip of building insulation wound in a roll around said core in coils such that a free edge the outside-most coil of the roll is the head of the roll, wherein the building is surrounded by a job site that has a ground such that a plurality of said bulk rolls of insulation are distributed about on the ground; said apparatus comprising: an aerial work platform for carrying a worker aloft and having a floor for the worker as well as a handrail; a pair of spaced spars extending between base ends mounted fixed relative to the aerial work platform, and, terminal ends; wherein said spars are mounted to project away from the aerial work platform such that the spars hold one bulk roll of building insulation below the elevation of the handrail; an elevator carrying the aerial work platform and adapted to lift the aerial work platform from the ground to the upper attachment extreme; wherein said spars are further mounted to project away from said aerial work platform so that the spars can be lowered by the elevator to where the spaced terminal ends of the spars straddle the opposite ends of the core of one roll on the ground for loading the roll onto said apparatus, whereby no worker has to manually lift any roll to load the roll between the spars and, thereby, the upper limit of the weight of a roll which can loaded and handled by said apparatus is determined by factors including the lifting capacity of the elevator, but not the limit of the manual strength of one or more workers; engaging provisions associated with the terminal ends of the spars for rotatably engaging the core of said one roll by or through the opposite ends of said core and thereby allowing the insulation to be unrolled from said one roll and applied to the wall or frame of the building in the form of vertical strips; and a tensioning control mechanism for controlling the unrolling of the roll.
