Abstract

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 exhausted.

Claims

1. In a dispenser for dispensing a web from a roll of paper, said dispenser including a housing and a housing cover connected thereto to provide access to the housing interior, said housing defining a dispensing outlet and including means for supporting a first paper roll within said housing and means for supporting a second paper roll, each of said first and second paper rolls initially having paper and a free end thereof, a drive roller and tension means operatively associated therewith urging paper from one of the first and second paper rolls into contact with said drive roller for dispensing a length of paper from the respective paper roll having paper in contact with said drive roller, drive means for rotating said drive roller including actuator means operatively connected to said drive means for rotation thereof, the improvement comprising a transfer roller having a clip for releasably holding the free end of the first paper roll while paper from the second paper roll is dispensed upon actuation of said actuator means to rotate said drive means and said drive roller connected thereto, the paper from said second paper roll being positioned between said drive roller and said transfer roller, thereby preventing rotation of said transfer roller during rotation of said drive roller until the paper of the second paper roll is exhausted whereupon further rotation of said drive roller causing rotation of said transfer roller to cause the free end of the first paper roll to be released from the transfer roller and to be dispensed from said housing through said dispensing outlet.

2. The dispenser of claim 1, wherein said transfer roller is disposed such that at least a portion thereof is in contact with said drive roller when the second paper roll is exhausted, such that rotation of said drive roller rotates said transfer roller, said tension means being positioned to form a nip with said drive roller such that rotation of said transfer roller due to the absence of paper between said transfer roller and said drive roller causes the free end of the first paper roll to enter the nip to be dispensed from said housing by further rotation of said drive roller.

3. The dispenser of claim 2, wherein said portion of said transfer roller carries said clip for releasably holding the free end of the first paper roll.

4. The dispenser of claim 3, wherein said portion of said transfer roller is generally cylindrical having a surface segment removed and in registry with said clip to accommodate a thickness of paper from the first paper roll between said clip and said cylindrical portion.
