ABSTRACT:
A roll of sheet material is supported on two spaced apart support rollers. During each dispensing cycle, the angular displacement of one of the support rollers is limited by a mechanism which includes a rotary member and a pivoted member. The rotary member carries a projection and is driven in an amount proportional to the amount of support roller movement. The pivoted member has an abutment surface and a reset surface. The abutment surface and the reset surface are positioned so the projection approaching the pivoted member contacts the abutment surface before coming to the reset surface. The abutment surface lies in the path of the projection to stop rotation of the rotary member and thus stop dispensation of the sheet material. A handle moves the pivoted member to withdraw the abutment from the projection path and to move the reset surface into the projection path. Movement of the projection against the reset surface moves the pivoted member to bring the handle over-center and return the abutment surface to its projection-abutting position where it will stop the movement of the rotary member upon completion of one revolution. This stops dispensation of sheet material until the handle is operated again to withdraw the abutment from the projection path.
