摘要:
A portable, compact, unitized device for transferring articles by pneumatic means from a processing machine to a collection receptacle includes a chamber divided into two compartments by a perforated plate, and having a releasable closure cap at one end and a trap door at the opposite end. A port in one compartment is coupled to a vacuum source, and a work inlet port in the other compartment communicates with a work processing means. An actuator, completely encompassed within one compartment and mounted upon the releasable closure, includes a shutter moveable axially of the vaccum source port for controlling air flow through the compartments.
