A dispenser for sheet materials comprising:
- a housing having an interior volume so as to retain at least one roll of sheet material, the housing including;
- a dispensing mechanism contained within the housing for dispensing the sheet material;
- wherein the dispensing mechanism comprises:
- a drive roller configured to a drive wheel, wherein the drive wheel is configured to a driven wheel having an extension spring attached thereto;
- and
- a stop release member having a first end and a second end, wherein the second end of the stop release member is configured to engage a stop member configured to the driven wheel, such that rotation of the drive roller, drive wheel, and driven wheel is stopped upon the stop member engaging the second end of the stop release member, wherein tearing the sheet material moves the second end of the stop release member out of engagement with the stop member allowing for stored energy in the extension spring to rotate the drive roller via the driven wheel and drive wheel to dispense a tail of the sheet material.
