Patent ID: 8578826

Claim:
A sheet material dispenser comprising: a housing; a sheet material roll holder; rotatable first and second rollers forming a nip therebetween, the first roller having a generally cylindrically-shaped body biased toward a resting position and being positioned in the housing such that (1) the sheet material passes through the nip and wraps partially around the first roller during sheet material pulling and (2) movement of the sheet material rotates the first roller in a dispensing direction; a stop member rotatable about an axis and which co-rotates with the first roller, the stop member having a radially-outward peripheral surface that includes a substantially radial stop surface at a single position therealong which defines a circular path upon stop-member rotation; a controlled member adjacent to the circular path and movable between a first position in which the controlled member is extended and intersects the circular path such that the stop surface contacts the controlled member in a single rotational position of the stop member to pause the co-rotation of the stop member and the first roller while in such first position also allowing the co-rotation in all other rotational positions of the stop member, and a second position in which the controlled member is retracted to release the stop surface after the pause to permit further co-rotation to the resting position; and a control circuit, responsive to co-rotation of the stop member and the first roller, triggering movement of the controlled member to the second position after pausing first roller the co-rotation for a delay time.
