DISPENSER FOR COILED MATERIAL HAVING IMPROVED OPERATOR ACTUATOR AND DRIVE MECHANISM

摘要

Dispenser for Coiled Material Having Improved Operator Actuator and Drive Mechanism A dispenser for coiled material has an improved operator actuator and drive mechanism. An actuator or button is conveniently located on the front of the dispenser, and the actuator or button, when pressed or pushed by the operator, activates a horizontally reciprocative gear rack to drive a drive roller and an idler roller to dispense a predetermined length of coiled material from the dispenser. The horizontally reciprocative gear rack has grooves which act on the drive gear to move the drive roller in a given direction when actuated by the operator. A ratchet/slip clutch interconnects the drive gear and drive roller so as to provide for unidirectional movement of the drive roller, that is, movement of the drive roller in one direction when the user pushes the actuator, and no movement of the drive roller when the actuator is released by the operator and returns to its original position. An idler gear on the idler roller and a drive gear on the drive roller coact to cause the idler roller and the drive roller to rotate in unison but in opposite directions.
