Abstract
An air powered storage device is provided that is operative to temporarily store pneumatic carriers within a pneumatic carrier system. Generally, the device includes a pneumatic tube that is sized to permit the passage of pneumatic carriers. A gate member is selectively positionable into and out of an internal bore of the pneumatic tube to impede movement of pneumatic carriers there through. The device further includes a blower having a first fluid inlet disposed on a first side of the gate member and a fluid outlet disposed on a second side of the gate member. The fluid inlet and outlet are fluidly interconnected to the internal bore of the pneumatic tube such that the blower is selectively operable to generate a fluid flow through the internal bore between the fluid outlet and the fluid inlet. Such fluid flow may be utilized to reinitiate movement of a stopped carrier.
