ABSTRACT:
A vertical stack of tablets is disposed in a tubular container extending upwardly from an opening in the top wall of a housing. The tablets are dropped one-by-one in front of a reciprocable pusher, which is driven by a rotary impeller and is effective to eject the lowermost tablet out from under the stack and into a sump in the housing, where it may be dissolved by water in the sump. The impeller is driven by a jet of water from a nozzle which receives water under pressure from a conduit leading into the housing. Water under pressure from this same conduit operates a settable ratchet device and a jet-deflector so that, when the desired number of tablets have been dispensed, the jet is deflected and the impeller is stopped to stop the reciprocation of the tablet-dispensing pusher.
