Abstract: A dispenser for flexible sheet material to carry multiple rolls of material such as paper toweling with dispensing mechanism being provided to lead a web of material out of the dispenser to the user. While one roll is in an initial dispensing position a reserve roll is held latched in a reserve non-dispensing position with the latching being released by cam means upon sensing that the one rolls is substantially depleted of sheet material whereupon the reserve roll moves to be driven in relation to the initial roll. While the remaining sheet material on the initial roll is withdrawn from the dispenser by the user the leading end of the sheet material on the reserve roll joins with such remaining sheet material to be led through said dispensing mechanism to be available to the user when the remaining sheet material on the initial roll is exhausted.

Abstract: A mechanism for cutting a web of flexible sheet material which is adapted to be used in a dispenser having a feed roller and a pinch roller between which rollers the web passes. A knife is pivotally mounted in the feed roller to swing about an axis laterally displaced from the plane of a radially outward portion of the knife defining a cutting edge which edge is projected outwardly beyond the periphery of the feed roller to cut the web as it passes over the feed roller and cam followers are carried by the ends of the knife extending beyond the ends of the feed roller with the followers displaced from the pivot mounting axis of the knife. Stationary cams are mounted adjacent the ends of the feed roller with which the cam followers on the knife engage to positively project the knife cutting edge beyond the feed roller periphery and retract the cutting edge upon rotation of the feed roller.

Abstract: A dispenser for flexible sheet material having a reserve roll that automatically moves into the dispensing position when the dispensing roll is almost exhausted. The sides of the reserve roll guide tracks are angled inwardly to engage the reserve roll spool at an off center point, so the spool is pushed downwardly into contact with a driving roller during rotation. The leading edge of the reserve roll towel engages the remaining portion of the almost exhausted dispensing roll and is moved therewith to be threaded through the dispensing mechanism. The perforating mechanism is assisted through the perforating stroke by a spring mechanism. The sensing roll is halted by a roll stop mechanism including a pivoted stop link and an anti-reverse pawl.

Abstract: A dispenser for liquids, including a supporting chassis, a supply tank for the liquid, a pump and a nozzle for conveying the liquid to the user of the dispenser. The nozzle has a housing member with an internal passage extending therethrough and has an insert and associated compressively elastically deformable sleeve positioned within. The insert has a passage extending from an opening in one end to at least one side opening, and the sleeve is interposed between the housing member and the inert with the portion of the sleeve adjacent the housing member being related against radially outward deflection by the housing member. The portion of the sleeve adjacent the insert encases the portion of the insert having the side opening to normally seal the side opening and thus prevent the liquid from leaking out of the nozzle.
