Abstract
Abstract A dual, power driven dispenser for dispensing rolled material such as paper. Two power driven rolls are provided, each being operable by a manual control which also opens one of two dispensing doors for the web or strip of paper which is being dispensed. The web is torn off after the door closes. A single drive motor is provided for operating both the power driven rollers through two separate gear trains. Each gear train is brought into driving engagement with the motor when its respective roller is to be driven. Each manual handle embodies an adjustable key member and a mechanism to make possible manual operation without driving either power driven roller.
