Pneumatic tube carriers often become wedged in locations within pneumatic tube assemblies that are inaccessible without dismantling the entire assembly. The causes of carriers becoming lodged include, but are not limited to, overloading and improper use.
The Pneumatic Carrier Extraction Device mechanism enables a wedged carrier to be selected and dislodged with minimal disassembly.
A metal component extraction device for a pneumatic carrier employs a hooking mechanism to select and dislodge a wedged carrier within a pneumatic tube assembly. The hooking mechanism is activated by springs when the carrier contacts the integral hinge arm thus enabling the hook to select the carrier in order for extraction from wedged location in the pneumatic tube assembly. Items 1, 3, and 5 in the Figures below are manufactured through the use of a computer numerical control machine. Metal springs, rivets, and screw caps—items 2 and 4 in the Figures below—are installed to complete the assembly of the device.
