The dispenser has a plurality of dispensing stations, each containing a rotary index wheel which picks up a succession of straws from a hopper and delivers them one after another into a separate chute which guides the straws into a separate delivery tube positioned directly above a beverage container. The index wheels at all of the stations index in response to a signal from the container making machine in synchronism to drop a set of straws into those tubes. Gates at the lower ends of the tubes open simultaneously and drop the set of straws then in the tubes into containers positioned below them before the new set of straws reaches the tubes.Field of SearchDispensing from plural sources by single actuationWith selection of number of sources Single discharge means successively loading from plural sources Pivoted wall section WITH TRANSPARENT INSPECTING OR VIEWING MEANS Means removing article from movable segregating chamber Spring pressed or gravity actuated finger Separately acting in series All rotary Motor-operated Compound motion Having movable segregating chamber (i.e., trap chamber) Axial inlet and outlet Rotary Single inlet-outlet With retractable pusher element Relatively movable actuator Lever or link Spring biased Rotary Dispensing plural articles Multiple, simultaneously acting and circumposed controllers With discharge means for each source | |
