Gas cylinder coupling and weighing mechanism for a carbonated drink dispenser.

摘要

A mechanism (740) useful in a dispenser (11) having a gas cylinder (17). Supports the cylinder rotatably within a hood (741), the hood forming a lever which is biased upwardly by a spring (765). A full cylinder will pull the hood all the way down. As the cylinder is emptied, the hood will begin to move upward and when the cylinder is empty the hood will be fully upward. Mounted inside the hood is a fitting (731) engaging with a mating fitting (709) on the gas cylinder. The mating fitting is equipped with a pair of arms which are aligned with locking slots contained within the mating fitting which are used to engage pins on the fitting inside the hood when mounting the gas cylinder.
