摘要： A dispenser for multiple rolls of web material such as paper toweling that is provided with dispensing mechanism to lead a web of material out of the dispenser to the user has supports for rotatably supporting rolls in primary and reserve positions, respectively, with transfer mechanism interactive with such roll supports and the dispensing mechanism to automatically transfer web feed from one roll to the other under predetermined sensed conditions. The transfer mechanism includes a pivotally mounted transfer frame swingable to be out of the way to facilitate dispenser loading with the dispenser cabinet cover open, the transfer frame being releasibly retained out of the way in conjunction with dispenser loading, and movable to a sensing location upon closure of the cabinet cover whereat depletion of web material supplied from the roll in the primary position is sensed whereafter the frame again shifts for tucking fingers on the transfer frame to press a web end portion of the reserve roll web material into the dispensing mechanism to thereafter feed web material from such reserve roll. A keeper bracket loosely receives this web end portion incident dispenser loading with the action of cabinet cover closing causing the bracket to firmly grip such portion until the transfer mechanism coacts with the dispensing mechanism to thereafter feed web material supplied from the reserve roll.

摘要： A device for rotatably supporting a roll of flexible sheet material having trunnions at the ends is provided with structure forming a friction brake to effectively control overspin of the roll during dispensing of the sheet material. The device involves an end support particularly configured to provide a bearing surface formed of resilient, high friction material effective to engage a portion of an end cap forming a roll trunnion, whereby the braking action provided by the bearing surface is directly proportional to the weight of the roll.

摘要： 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.

摘要： A dispenser and dispensing method for flexible web material that is wound into a roll on a transversely split core utilizes a housing having opposed parallel guide tracks to guidingly receive roll core supports projecting from the roll ends and a pivoted control lever providing a lever sensing end to detect the presence of an intact roll core in a roll dispensing position and an upper support end to retain a roll in a reserve roll position. The lever has its sensing end biased toward the intact roll core thereby tending to buckle the split core into sections upon exhaustion of web material from the intact roll core whereupon the core sections with their roll core supports are disengaged from the tracks and the reserve rolls is freed from the lever support end to move to the roll dispensing position.

摘要： 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. When the pump is actuated, the liquid compressively elastically deforms the portion of the sleeve adjacent the insert so that the sleeve is forced away from the insert side opening, and the liquid flows into the insert passage through the insert end opening, through the insert passage, out of the insert passage through the insert side opening, past the sleeve and out of the housing member passage.

摘要： A dispenser sequentially dispenses web material from a working web roll and then a reserve web roll. A web sensing mechanism senses the presence of the working web at a back side of the main feed roller and introduces the leading end of the reserve web roll to a feed nip defined by two feed rollers immediately after the trailing end of the working web roll passes over a back side of the feed roller. Web sensing, and controlled introduction of the leading end of the reserve web to the feed nip, are carried out by a simple and effective interaction of a grooved main feed roller, and a pair of pivotable lever arms—a web sensing arm mounted at the backside of the rollers, and a transfer arm mounted at the front side. The mechanism avoids double feeding of web by sensing the presence or absence of web at the back-side of the main feed roller. Transfer fingers of the transfer arm are movable against the reserve roll web and into corresponding grooves in the main feed roller such that a leading end portion of the reserve roll web is reliably moved into the vicinity feed roller nip, where serrations provided in the edges of the grooves facilitate a gripping of the leading end portion to pull the web through the nip. The feed path is arranged to extend away from the transfer fingers so as to avoid interference of the transfer fingers with the subsequent feeding of the web.

摘要： A dispenser for rolls of flexible sheet material wound on cores is disclosed. The dispenser holds multiple rolls and includes guide tracks for guiding the rolls through the dispenser. A holding lever pivotably connected to each side of the dispenser selectively holds the rolls in position in the dispenser and has its pivoting motion controlled by a sensing plate which contacts a lower dispensing roll to sense when the sheet material is substantially depleted. The lower dispensing roll is always held out of contact with rollers of a dispensing mechanism. A shield is located between the roll surface of the lower dispensing roll and the rollers of the dispensing mechanism.

摘要： A dispenser and dispensing method for flexible web material that is wound into a roll on a readily deformable hollow core has a housing carrying opposed parallel guide tracks to guidingly receive roll core supports projecting from the roll ends and a spring biased lever pivoted on such housing, the lever applying an axial force to the hollow core at one roll end and being maintained in a roll retaining condition by the presence, in a roll dispensing position, of a hollow roll core that is held against downward displacement from such position. An axial force is applied against the other end of the hollow core. The lever serves to retain a reserve roll in a reserve roll position remote from the roll dispensing position with the lever being released from such retaining condition when the web material is exhausted and the hollow core is deformed downwardly, assisted by the axial forces applied to the hollow core ends, to enable removal of this core from the roll dispensing position whereupon such reserve roll moves to the dispensing position.
