SHEET MATERIAL DISPENSER HANDWHEEL AND CUTTING KNIFE ABSTRACT A dispenser guides a web roll a roll of sheet material over a feed roller to a position to be grasped by the user while roller mounted knife means cuts the web into individual sheets and a man- ually engageable handwheel, rotatable with the feed roller, provides peripherally spaced finger notches to facilitate manual forward rotation of the roller in dispensing the material. The notches are formed differently in separate circumferential portions of the hand- wheel such that pawl means, successively engaging the notches inci- dent handwheel rotation, prevents reverse rotation of the feel roller throughout a first portion of each feed roller revolution and biasing means acts to cause reverse rotation throughout a second portion of the feed roller revolution to assure return of the knife means to a safe inaccessible location within the dispenser when the handwheel is released.
