One-revolution stop mechanism and dispensing method for rolled web dispensers

A dispenser for rolled web material comprising:

• a dispenser cabinet having means in said cabinet for mounting a roll of web material;
• a feed roller rotatably mounted on shaft means in said cabinet to guide web from the roll to the exterior of said cabinet;
• cutter mechanism associated with said feed roller to transversely perforate the web as it passes over said feed roller;
• control tab means rotatable with said feed roller and spaced radially from the feed roller axis;
• lever means mounted to pivot in a plane normal to said feed roller axis having a slot disposed to pass around said shaft means during pivoting movements of said lever means;
• lift flange means carried by said lever means disposed on one side of said slot to be engaged by said control tab means to raise said lever to a high level as said feed roller rotates;
• and
• stop flange means carried by said lever means on the other side of said slot to abuttingly frictionally engage said control tab means after said tab means has fully raised said lever means and passed from beneath said lift flange means, said stop flange means thereupon holding said lever means and preventing feed roller rotation until pulling tension on the web is terminated.
