Abstract

This specification discloses a turret for fire fighting equipment capable of delivering a plurality of fire extinguishing agents onto a fire, characterized by having a plurality of nozzle means connected respectively with a plurality of separate conduit means; a single support means adapted for effecting any segment of rotation, including 360* and more of rotation for the turret; and a plurality of concentric mounting and sealing means within the single support means. The concentric mounting and sealing means are each connected with respective ones of said conduit means to carry the respective fire extinguishing agents without admixing thereof and without entanglement of the respective conduit means. Also disclosed are specific elements; such as, the stationary external jacket serving as the single support means; the rotatable head; the respective conduit means; the swivel joints serving as the mounting and sealing means; the twin nozzles; and the disengageable locking means for effecting unitary operation of the twin nozzles, or allowing them to be operated separately.

Claims

1. In a fire fighting turret assembly for delivering a plurality of fire extinguishing agents on a fire, said turret assembly having a plurality of nozzle means connected with a plurality of conduit means for carrying respective said fire extinguishing agents, the improvement comprising:

a. a single support means including a stationary jacket and a rotatably connected head adapted for effecting any segment of rotation of said turret assembly up to and including full 360* of rotation; and

b. a plurality of mounting and sealing means concentric with said single support means, each being operatively connected to be rotatable with one of said conduit means so as to preserve the identity and characteristics of said respective fire extinguishing agents and prevent intertwining of said conduit means when said turret assembly is rotated through a plurality of complete circles in either direction.

2. A fire fighting turret capable of delivering a plurality of fluidized fire extinguishing agents for fighting a fire comprising:

a. a stationary external jacket for conveying a first fire extinguishing agent;

b. a head rotatably and sealingly mounted on said external jacket for conveying said first fire extinguishing agent;

c. first nozzle outlet means fixed to said head for delivering said first fire extinguishing agent to a nozzle means;

d. an internal conduit means rotatably and sealingly mounted within said external jacket and having second nozzle outlet means at one end sealingly and fixedly penetrating through the wall of said head for conveying and delivering a second fire extinguishing agent to a second nozzle means;

e. swivel fluid coupling means rotatably and sealingly connected with the other end of said internal conduit means, said coupling means being adapted for connection with a delivery conduit, said delivery conduit being connected with a source for said second fire extinguishing agent; and

f. fluid inlet coupling means sealingly penetrating the wall of said external jacket for connecting the interior thereof with a second delivery conduit, said second delivery conduit being connected with a source for said first fire extinguishing agent.

3. The turret of claim 2 wherein said external jacket serves as a support means about which said head can freely rotate throughout 360*.

4. The turret of claim 2 wherein there is provided a brake means for preserving azimuthal orientation of said head, said brake means being connected with said external jacket and operatively engageable with said head.

5. The turret of claim 2 wherein said first and second nozzle outlets each have a first ell means rotatably and sealingly connected therewith for effecting azimuthal orientation independently of said head and a second ell means rotatably and sealingly connected therewith for effecting elevational orientation, and a nozzle means connected therewith for effecting delivery of one of said fire extinguishing agents;

said first ell means, said second ell means, and said nozzle means being connected in series.

6. The turret of claim 5 wherein each of said nozzle means has physically connected with it a handle means and wherein there is provided a locking means for locking the plurality of handle means connected with the plurality of nozzle means together to effect unitary azimuthal and elevational orientation of saId nozzle means, said locking means being movable into an unlocked position whereby said respective nozzle means can be oriented along separate azimuthal and elevational orientations.

7. The turret of claim 6 wherein each said handle means has affixed thereto a control means to render delivery of said respective fire extinguishing agents responsive to an operator controlling the orientation of said handle means and, hence, said nozzle means.
