The latch dog assembly is inwardly biased and disposed adjacent at least one of the spindles. The latch dog is configured so that it is urged outwardly to a locking position upon disposing a roll of absorbent sheet about its adjacent spindle and is biased inwardly to a release position upon depletion of the roll of absorbent sheet material disposed about its adjacent spindle.
