Patent ID: 7928585

Claim:
Apparatus for aligning a plurality of layers comprising, a sprocket of diminishing diameters as the sprocket extends outwardly from a base, and further comprising at least an abutting layer and an abutted layer wherein said abutting layer and said abutted layer comprise a plurality of sprocket openings in each of said layers for receiving said sprocket, the center axes of said sprocket openings being substantially alignable with one another, the largest diameter of said sprocket openings in said abutting layer for first receiving said sprocket being greater than the largest diameter of said sprocket openings in said abutted layer, a plurality of reservoir openings in each of the layers comprising at least an abutting layer and at least an abutted layer, the center axes of the reservoir openings being substantially alignable with one another, the sprocket openings in the layers being positioned to correspond with one another and the reservoir openings in the layers being positioned to correspond with one another, said sprocket openings being arranged so that inserting the end of said sprocket having the smallest diameter into said sprocket openings having the largest diameter in said layers and continuing through to the sprocket opening having the smallest diameter in said layers effects substantial alignment of said center axes of said corresponding sprocket openings and substantial alignment of said center axes of said corresponding reservoir openings in said layers, the diameter of said sprocket openings and the corresponding diameter of said sprocket being arranged so that upon said insertion into said sprocket openings, said sprocket substantially abuts sprocket openings in corresponding layers but also allows said layers to substantially abut against one another and substantially prevent layer separation during said alignment.
