Abstract

A dual-agent fire fighting turret has an annular first conduit for a first fire extinguishing agent concentrically positioned around a second conduit for a second fire extinguishing agent. The first and second conduits are contained within a rotating outer jacket. The first conduit is connected in flow communication to a first, dual-arm, yoke outlet conduit, which in turn is pivotably connected in flow communication with a first delivery tube. The second conduit is connected in flow communication with a second outlet conduit which is in turn pivotably connected in flow communication with a second delivery tube. A hollow elevation shaft is slidably mounted within and extends through the first and second conduits, the upper end being pivotably connected to the delivery tubes and the lower end having a control handle attached thereto. The control handle is also connected to the base of the rotating jacket so that vertical adjustment of the control handle adjusts the elevation of the delivery tubes, and rotation of the control handle orients the delivery tubes along a selected azimuth. Control cables are threaded through the elevation shaft and may be operated by control cable levers to operate cable actuated flow control devices located in the delivery tubes.

Claims

1. A dual fire extinguishing agent fire turret having a main body portion comprising a fixed base containing a rotatable outer jacket mounted therein;

first and second conduits within said main body portion, said first and second conduits each having respective outlets from said main body portion, said outlets being located in said outer jacket, a first delivery tube connected in flow communication with the outlet of said first conduit, and a second delivery tube connected in flow communication with the outlet of said second conduit, an elevation shaft slidably positioned within said main body portion, the upper end of said elevation shaft extending through an upper part of said main body portion and being pivotably engaged with said first and second delivery tubes, and the lower end of said elevation shaft extending through a lower part of said main body portion. means to permit said elevation shaft to be slidably moved relative to said main body portion, and means to permit rotation of said outer jacket relative to said fixed base.

2. The fire turret of claim 1 wherein said elevation shaft is hollow and at least one of said delivery tubes contains a cable actuated delivery tube control device, a control cable is threaded through said elevation shaft, and one end of said cable is connected to said delivery tube control device.

3. The fire turret of claiM 2 wherein said first delivery tube and said second delivery tube each contain at least one cable actuated delivery tube control device, at least two control cables are threaded through said hollow elevation shaft and connected, respectively, to said cable actuated delivery tube control devices.

4. The fire turret of claim 2 wherein said control cables are connected to cable control handles at the end of said cables opposite from the end which is connected to said cable actuated delivery tube control device.

5. The fire turret of claim 1 wherein said rotatable outer jacket contains two outlets for said first conduit, said two outlets are connected respectively to one each of the arms of a dual-arm yoke outlet conduit, and said first delivery tube is pivotably mounted upon said dual-arm yoke outlet conduit.

6. The fire turret of claim 5 wherein said elevation shaft is pivotably connected to said first delivery tube and said first and second delivery tubes are connected to each other by delivery tube connecting means.

7. The fire turret of claim 1 wherein the upper end of said elevation shaft is connected to one of said delivery tubes and said first and second delivery tubes are connected to each other by delivery tube connecting means.

8. The fire turret of claim 1 wherein said means to permit said elevation shaft to be slidably moved with respect to said main body portion is a control handle affixed to the lower end of said elevation shaft, said control handle also being affixed to said outer jacket to constitute said means to permit rotation of said outer jacket relative to said fixed base.

9. The fire turret of claim 1 wherein said first and said second conduits are concentrically positioned with respect to one another and with respect to said elevation shaft, and said elevation shaft is located at the center of concentricity.

10. The fire turret of claim 1 wherein said first conduit is annularly disposed about said second conduit.

11. The fire turret of claim 1 wherein a delivery tube is adjustably connected to said turret.

12. The fire turret of claim 11 wherein the adjustable connection of said delivery tube is provided by connecting said delivery tube to one end of an outlet conduit by a swivel mounting, and connecting the other end of said outlet conduit to said turret by a swivel mounting.

13. The fire turret of claim 11 wherein the adjustable connection of said delivery tube is provided by connecting said delivery tube to one end of a flexible outlet conduit, the other end of which is connected to said turret.

14. A dual fire extinguishing agent fire turret comprising a first conduit connected in flow communication with a dual arm outlet conduit, thence with a first delivery tube pivotably connected to said dual arm outlet conduit, a second conduit connected in flow communication with a second delivery tube which is adjustably connected to said turret, said first conduit being annularly disposed about said second conduit, connecting means connecting said first delivery tube to said second delivery tube, an elevation shaft slidably mounted in said first conduit and extending therethrough, the upper end of said elevation shaft being pivotably engaged with said first delivery tube and the lower end of said delivery shaft extending through and below the lower end of said first conduit, said first and second conduits being rotatably mounted in a fixed base whereby rotation of said first and second conduits rotates their associated delivery tubes in an azimuth plane, and said elevation shaft being slidable relative to said first and second conduits so that sliding movement of said elevation shaft relative to said first and second conduits adjusts the elevation of said delivery tubes.

15. The fire turret of claim 14 wherein said elevation shaft is mounted in a guide sleeve which extends through said second conduit and is sealed to respectively, the upper and lower ends thereof.

16. The fire turret of claim 14 wherein said elevation shaft is a hollow tube and at least one control cable is threaded through said elevation shaft, with an upper end of said at least one control cable connected to a cable actuated flow control device, and the lower end of said at least one control cable is connected to a cable control handle.

17. The fire turret of claim 14 wherein a control handle is connected both to the lower end of said elevation shaft and to the lower end of at least one of said first and second conduits whereby rotation of said control handle effects rotation of said first and second conduits and vertical movement of said control handle effects sliding movement of said elevation shaft relative to said first and second conduits.

18. The fire turret of claim 14 wherein said elevation shaft and said first and second conduits are connected to motors, the operation of which effects adjustment of the elevation of said elevation shaft and rotation of said first and second conduits.

19. The fire turret of claim 18 wherein said first and second conduits are contained within an outer jacket which is rotatable with respect to said fixed base and said outer jacket is connected to said motors.
