The second system is the one used by [[Crocker]] around 1910, in this case the bottom itself is anchored to a lever, which raised in a vertical position compresses the sac. To be used the bottom was unscrewed, after which the lever could be operated. Holding it screwed in, the lever was locked in the rest position, thus avoiding accidental pressure.
