A low reserve indicator mechanism for a supply of paper towels is disclosed. The mechanism includes a base, a pushplate, and an indicator. The pushplate is connected to the base with a translational degree of freedom therebetween, is biased in a first direction relative to the base, and is responsive to a first attribute of the supply of paper towels to translate opposite the first direction. The indicator is pivotally connected to the pushplate, and is movable between a retracted position and an indicating position in response to a second attribute of the supply of paper towels.

What is claimed is: 1. A low reserve indicator mechanism for a supply of paper towels, the mechanism comprising: a base; a pushplate connected to the base having a translational degree of freedom therebetween, the pushplate biased in a first direction relative to the base and responsive to a first attribute of the supply of paper towels to translate opposite the first direction; and an indicator pivotally connected to the pushplate, the indicator movable between a retracted position and an indicating position in response to a second attribute of the supply of paper towels. 2. The mechanism of claim 1, further comprising: a release arm pivotally connected to and biased away from the pushplate, the release arm operably connected to the indicator and responsive to the second attribute to cause the indicator to move between the retracted position and the indicating position. 3. The mechanism of claim 2, wherein the indicator is connected to the release arm via a cam and cam follower. 4. The mechanism of claim 2, wherein the release arm is connected to the indicator by a pin and slot. 5. The mechanism of claim 2, wherein: the release arm comprises a rib responsive to the second attribute. 6. The mechanism of claim 1, wherein: the second attribute comprises a predetermined amount of the supply of paper towels; and the indicator is responsive to an amount of the supply of paper towels being reduced below the predetermined amount to move to the indicating position. 7. The mechanism of claim 6, wherein the second attribute is defined by an edge of the supply of paper towels formed by superimposed edge portions of the supply of paper towels. 8. The mechanism of claim 1, wherein the indicator comprises an indicia-carrying sign. 9. The mechanism of claim 1, wherein the supply of paper towels is a roll of paper towels having an exposed inner periphery from which towels are dispensed. 10. The mechanism of claim 9, wherein the second attribute is an edge defined by the inner periphery and superimposed edge portions of the supply of paper towels. 11. The mechanism of claim 9, wherein the first attribute is an outer diameter of the roll of paper towels. 12. The mechanism of claim 11, wherein the pushplate comprises protrusions responsive to the outer diameter of the roll of paper towels to translate the pushplate opposite the first direction. 13. A dispenser for a supply of paper towels, the dispenser comprising: a housing having a first section movably affixed to a second section, the first section and the second section defining an inner chamber and a dispensing aperture; and a low reserve indicator mechanism comprising: a base attached to at least one of the first section and the second section; a pushplate connected to the base having a translational degree of freedom therebetween, the pushplate biased in a first direction relative to the base and responsive to a first attribute of the supply of paper towels to translate opposite the first direction; and an indicator pivotally connected to the pushplate, the indicator movable between a retracted position and an indicating position in response to a second attribute of the supply of paper towels. 14. The dispenser of claim 13, the low reserve indicator further comprising: a release arm pivotally connected to and biased away from the pushplate, the release arm operably connected to the indicator and responsive to the second attribute to cause the indicator to move between the retracted position and the indicating position. 15. The dispenser of claim 13, wherein at least one of the first section and the second section comprise a guide to position the supply of paper towels within the inner chamber of the housing. 16. The dispenser of claim 15, wherein the second section is fixedly attachable to a wall, and the guide is disposed upon the first section. 17. The dispenser of claim 15, wherein the guide comprises a rib disposed to contact an outer diameter of a roll of paper towels in response to the first section being pivotally closed and affixed onto the second section. 18. The dispenser of claim 13, wherein the dispensing aperture is disposed proximate a center of the housing to dispense the supply of paper towels from an exposed inner periphery of a roll of paper towels. 19. The dispenser of claim 18, wherein the first attribute of the supply of paper towels is an outer diameter of the roll of paper towels. 20. The dispenser of claim 13, wherein: the second attribute comprises a predetermined amount of the supply of paper towels; and the indicator is responsive to an amount of the supply of paper towels being reduced below the predetermined amount to move to the indicating position. 21. The dispenser of claim 13, wherein: the second attribute comprises a predetermined amount of the supply of paper towels; and the indicator is responsive to movement of either the first section or the second section toward the other of the first section and the second section and an amount of the supply of paper towels being greater than the predetermined amount to cause the indicator to move to the retracted position. 22. The dispenser of claim 13, wherein the low reserve indicator mechanism is attached to at least one of the first section and the second section such that the indicating position of the indicator, in response to the second attribute of the supply of paper towels, is visible via an exterior of the dispenser. 23. The dispenser of claim 13, wherein: the base further comprises a first attachment feature; the housing comprises a second attachment feature disposed within the inner chamber; and the first attachment feature engages the second attachment feature, thereby attaching the base to the housing within the inner chamber. 24. A low reserve indicator mechanism for a supply of paper towels, the mechanism comprising: a base; an indicator coupled to the base with a first translational degree of freedom and a first rotational degree of freedom therebetween; a release arm coupled to the base with a second translational degree of freedom and a second rotational degree of freedom therebetween; and a pushplate coupled to the base with a third translational degree of freedom therebetween; wherein the first, second and third translational degrees of freedom are coincidental; and wherein the first rotational degree of freedom and the second rotational degree of freedom are coupled such that rotation of the release arm causes rotation of the indicator. 25. The mechanism of claim 24, wherein the coincidental translational degrees of freedom accommodate towel rolls of the supply of paper towels having varying outer diameters independent of the first and second rotational degrees of freedom accommodating an indication of a low supply of the supply of power towels.
