Paper towel dispenser apparatus

Paper towel dispenser apparatus for dispensing paper toweling from a roll of paper toweling responsive to a pulling force being applied to said toweling, said apparatus comprising, in combination:

• a housing;
• a roll support operatively associated with said housing for rotatably supporting the 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 having an external surface and being rotatable in a predetermined direction of rotation when a manual pulling force is applied to toweling supported thereby;
• a cutter blade located at the cylindrically-shaped outer peripheral portion and having a cutting edge, said cutter blade being pivotally movable between a first condition wherein said cutter blade does not project substantially outwardly from the external surface of said cylindrically-shaped outer peripheral portion and a second condition wherein said cutter blade projects outwardly from the external surface of said cylindrically-shaped outer peripheral portion with the cutting edge thereof spaced from the external surface of said cylindrically-shaped outer peripheral portion;
• blade actuator means for pivoting said cutter blade between said first and second conditions responsive to rotation of said toweling support roller due to the manual pulling force being applied to said toweling at a location externally of said housing and tensioning of said toweling, the cutting edge of the cutter blade when said cutter blade is in said second condition engaging toweling on the toweling support roller during rotation of the toweling support roller to sever the toweling to create a towel sheet severed from the remainder of said paper toweling due to said manual pulling force and tensioning of said toweling between the cutting edge of the cutter blade and the location on said toweling where the pulling force is applied, and said toweling support roller being rotatable after severing of said toweling to position a lead end of the remainder of said toweling for subsequent manual pulling;
• and
• a rotatable toweling engagement roller forming a nip with said toweling support roller in engagement with the remainder of said toweling, said cutter blade being substantially flat against the toweling support roller with the cutting edge thereof positioned closely adjacent to the external surface of said cylindrically-shaped outer peripheral portion when in said first condition and wherein said cutter blade when in said second condition projects outwardly from the external surface and is disposed at an acute angle with respect thereto, projecting outwardly in a direction generally opposed to the direction of rotation of said toweling support roller, and said cutter blade pivoting about a pivot located at the external surface, said cutter blade during rotation of said toweling support roller being movable between said first condition through said second condition to a third condition wherein said cutter blade is disposed generally orthogonal to said external surface, said rotatable toweling engagement roller forming said nip with said toweling support roller at a predetermined location enabling said toweling support roller to rotate at least about 180 degrees from passage of said cutter blade under said rotatable toweling engagement roller with said cutter blade in said first condition to a subsequent location wherein said cutter blade is in said third condition, said toweling remaining in engagement with and supported by said toweling support roller during said at least 180 degrees of rotation.
