Abstract
A roofing washer-dispensing machine having improved features is disclosed. A novel magazine comprises a substantially box-like container with a substantially open face, for housing a stack of circular roofing washers having inserts, and a substantially rigid rod removably mounted within or upon to a top wall of the box so as to extend downwardly into the central apertures of the stack washers, except for the lowermost washer, so as to restrain the remaining washers. The machine comprises a shuttle arranged to displace the lowermost washer from the stack when it is desired to dispense such washer. The shuttle includes a novel arrangement of means overlying and underlying marginal portions of such washer.
