Claims
- 1. A pneumatic outlet comprising: side walls, end walls and a lower housing forming an interior chamber; a valve member mounted within the interior chamber for controlling the flow of lading from said outlet; a tubular conduit rotatably mounted on and extending from at least one end of said outlet and communicating at one end with the interior chamber; means interconnecting said valve member and said tubular conduit whereby rotation of the tubular conduit actuates the valve member to control the flow of lading from the outlet; said tubular conduit having a cylindrical outer surface; a hub member having at least one handle extending therefrom mounted for rotary and axially sliding movement on the cylindrical surface; clutch means on the tubular conduit and on the hub member which interengage in one axial position of the hub and disengage in another axial position of the hub whereby when the clutch means are engaged, the tubular member is connected to said hub and is rotated when said hub member is rotated by the handle, and when said clutch means are disengaged, the hub is free to rotate without rotating the tubular conduit whereby the handle and hub may be re-positioned; said conduit having at least one annular surface adapted to engage a hose coupling for discharging the outlet; a removable end cap in closed position covering said annular surface; locking means on said cap for maintaining said cap in closed position; and indexing means on said cap and said hub for insuring that when said cap is applied to the outlet said hub is in proper position for rotating said valve when limited clearance exists below said outlet.
- 2. A pneumatic outlet according to claim 1 wherein said indexing means comprise a protrusion on said cap which engages a slot in said hub when said handle is in proper position for rotating said valve.
- 3. An outlet according to claim 2 wherein said locking means comprises a locking handle pivotally mounted on said cap and a locking member affixed to said locking handle which engages a keeper mounted on said end when said cap is in closed and locked position.
- 4. An outlet according to claim 3 wherein said locking member is generally U-shaped and wherein said keeper includes a hook portion which engages said locking member when said cap is in closed and locked position.
