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.

Entrambi questi sistemi si possono annoverare fra i vari tentativi di creare un sistema di compressione del sacchetto basato su meccanismi che si distinguessero da quelli brevettati dagli altri produttori. Data la relativa complessità realizzativa e la tutto sommato scarsa efficienza tecnica, entrambi non hanno avuto alcun seguito significativo. La loro rarità li rende però interessanti dal punto di vista collezionistico.<noinclude>

Both of these systems can be counted among the various attempts to create a bag compression system based on mechanisms that differed from those patented by other manufacturers. Given the relative complexity and the low technical efficiency, both have not had any significant follow-up. Their rarity, however, makes them interesting from a collector's point of view.<noinclude>
