A dispenser for dispensing a web from a roll of paper includes a housing and a cover connected thereto to provide access to the housing interior. The dispenser has mechanism for supporting a paper roll and a drive roller and tension roller operatively associated therewith which urges paper from the paper roll into contact with the drive roller for dispensing a length of paper from the paper roll. Actuator mechanism operates the drive roller and extends across substantially the entire housing at the bottom thereof. A roller frame assembly is mounted within the housing and carries the tension roller and a transfer roller. The transfer roller releasably holds the free end of a first paper roll while paper from the second roll is dispensed upon actuation of the actuator to rotate the drive roller. Because the paper from a second paper roll is positioned between the drive roller and the transfer roller, rotation of the transfer roller during rotation of the drive roller is prevented until the second paper roll is exhausted.

[ What is claimed is:] [1.]1. In a dispenser for dispensing a web from a roll of paper, said dispenser including a housing and a housing cover connected thereto movable between a closed position and an open position to provide access to the housing interior, said housing defining a dispensing outlet and including means for supporting a paper roll within said housing, a drive roller rotatably mounted inside said housing for dispensing a length of paper from the paper roll, drive means for rotating said drive roller including actuator means operatively connected to said drive means, the improvement comprising a roller frame assembly mounted within said housing carrying a tension roller thereon, said roller frame assembly being movable between a use position wherein said tension roller contacts a paper web from the roll of paper urging the paper web against said drive roller and a maintenance position wherein said housing cover is in its open position and said roller frame assembly is spaced away from said drive roller to provide access to the housing interior and to said means for supporting a paper roll, and said roller frame assembly being movable between said use position and said maintenance position independently of the housing cover, said roller assembly being biased by gravity toward its maintenance position such that when said housing cover is in its open position said tension roller is spaced away from said drive roller permitting easy insertion of a paper web therebetween, and said roller frame assembly carries spring means contacting said housing cover when in it's closed position urging said roller frame and said tension roller toward said driver roller to maintain frictional contact between the paper web and said drive roller, whereby movement of said actuator when said housing cover is in its closed position and said roller frame is in its use position operates said drive means to rotate said drive roller causing paper in contact therewith to be unwound from the paper roll and dispensed through said dispensing outlet.
