Abstract:
1. A dispenser for dispensing and advancement of sheet material, comprising: a drive roller rotationally mounted to a frame; a sheet material engaging said drive roller such that pulling of said sheet material causes tension in said sheet material and causes said drive roller to rotate; a segmented gear rotationally mounted to the frame, wherein said segmented gear is in communication with said drive roller, and wherein said segmented gear has a first and second drive segment; a spring in communication with said segmented gear such that rotation of said segmented gear in a first direction caused by pulling of said sheet material causes said spring to store potential energy; and a cutting blade in communication with said segmented gear, said cutting blade configured for cutting said sheet material such that tension in said sheet material is released after cutting; wherein release of tension in said sheet material causes said spring to release potential energy that causes said segmented gear to rotate in a second direction in order to cause said drive roller to rotate and advance said sheet material.
