A dispenser for feeding perforated paper towels from a continuous roll of paper towels. The apparatus includes a dispenser body for containing the towel roll and an adjustable nozzle attached to the dispenser body for dispensing an end portion of the continuous roll. The nozzle includes a base having a centralized opening; an upper blade having a first cutaway portion; and a lower blade slidably nested with the upper blade, the lower blade having a second cutaway portion which aligns with the first opening to form a unitary opening aligned with the base centralized opening. A cam assembly is positioned adjacent to one of the upper and lower blades for selectively adjusting the size of the unitary opening. At least one gear is connected to the base and intermeshing with at least one gear rack positioned on the upper and lower blades. The gear provides for equal movement between the upper blade and the lower blade when the opening is adjusted. A removable slide having a locking tab selectively locks the slide to the nozzle for maintaining the nozzle opening in a preset position. Also, the cam assembly positioned adjacent to one of the upper and lower blades for selectively adjusting the size of the unitary opening is attached to the slide whereby removing the slide removes the cam assembly and allows at least one of the blades to open to permit the roll of paper towels to be more easily replaced.
