ABSTRACT:
An improved pneumatic tube carrier is provided for transmitting papers, currency and other articles between various stations at locations within a building or building complex. The carrier hull is constructed of identical mating sections each formed in a generally semi-cylindrical shape from a single mold. The semi-cylindrical halves are hinged together along one longitudinal interface. A closure mechanism is provided at the opposite interface and includes a catch spring biased toward the hull. An adjustment mechanism limits the movement of the catch relative to the hull. Adjustment is possible to correct for catch disposition variations with prolonged use. Proper adjustment allows the hull to be self-latching upon closure. Adjustment is effectuated with the hull closed through a perforation near the hinged interface of hull sections, whereby an elongated tool is inserted into the perforation and is used to alter the adjusting mechanism.
