US Patent 7290733 Dispenser for rolled materials

A dispenser for paper, plastic, foil and other goods that are supplied on rolls or tubes includes a rotation mechanism, such as a spindle, including a plurality of bows for engaging an inner surface of a roll. The spindle rotates about an end cap assembly. A mechanism provides resistance against spindle rotation about the end cap assembly. The end cap assembly is configured with an extending first shaft, aligned with an axis of rotation of the spindle, used to hang one end of the dispenser from a bracket. The dispenser further includes a spring loaded end cap including an extending second shaft, also aligned with an axis of rotation of the spindle, used to hang another end of the dispenser from the bracket. From the end cap assembly, a radially extending projection is provided. The projection includes a stop knob which functions to engage the bracket from the dispenser is hung and prevent the end cap assembly from rotating about the first and second shafts.
