Abstract
Apparatus for dispensing paper toweling includes a rotatable toweling support roller and a cutter blade pivotally mounted on the outer peripheral portion of the roller. The blade is movable between a first position in which the cutting edge of the blade is positioned closely adjacent to the outer peripheral portion and a second position in which the blade is disposed at an angle relative to the outer peripheral portion with the cutting edge of the blade spaced from the toweling support roller. The cutter blade when in the second position projects in a direction generally opposed to the direction of rotation of the toweling support roller so that pulling force exerted on the toweling by a user will bear against the cutting edge of the cutter blade to sever the toweling.
Claims24
Paper towel dispenser apparatus for dispensing paper toweling from a roll of paper toweling responsive to pulling forces being applied to said paper toweling, said apparatus comprising, in combination:
- a housing;
- a roll support operatively associated with said housing for rotatably supporting a roll of paper toweling;
- a rotatable toweling support roller within said housing spaced from said roll support for receiving toweling from the roll of paper toweling and supporting the toweling, said toweling support roller having a cylindrically-shaped outer peripheral portion and being rotatable in a predetermined direction of rotation when pulling forces are applied to toweling supported thereby;
- a cutter blade having a cutting edge, said cutter blade pivotally mounted on said toweling support roller about a pivot located at the cylindrically-shaped outer peripheral portion and pivotally movable between a first position wherein said cutter blade lies substantially flat against the toweling support roller with the cutting edge thereof positioned closely adjacent to the cylindrically-shaped outer peripheral portion and a second position wherein said cutter blade is disposed at an angle relative to said cylindrically-shaped outer peripheral portion with the cutting edge thereof spaced from said toweling support roller, said cutter blade when in said second position projecting from said pivot in a direction generally opposed to the direction of rotation of said toweling support roller;
- and
- blade actuator means for pivoting said cutter blade between said first and second positions responsive to rotation of said toweling support roller due to a pulling force being applied to toweling on said toweling support roller and tensioning of said toweling, the cutting edge of the cutter blade when said cutter blade is in said second position engaging toweling on the toweling support roller during rotation of the toweling support roller to sever the toweling due to said pulling force and tensioning of said toweling.
A method of dispensing paper toweling from a roll of paper toweling, said method comprising the steps of:
- positioning paper toweling extending from a roll of paper toweling and having a lead end on a rotatable toweling support roller;
- pulling the lead end of the toweling to tension the toweling and cause rotation of the toweling support roller;
- while said toweling is under tension and during rotation of the toweling support roller, pivoting a blade connected to the toweling support roller to bring a cutting edge of the blade into engagement with the underside of toweling on said toweling support roller and to a cutting position in which said blade is disposed at an angle relative to the outer peripheral surface of the toweling support roller with the cutting edge thereof spaced from the toweling support roller and the blade projecting in a direction generally opposed to the direction of rotation of said toweling support roller;
- and
- maintaining the toweling under tension by continuing to apply a pulling force thereto while said blade is in said cutting position and the cutting edge thereof engages the paper toweling to sever the paper toweling.
