Fire fighting turret

DETAILED DESCRIPTION In general, the invention consists of a fire fighting turret having apparatus for joining for the flow of fire extinguishing medium from a fixed inlet pipe to a universally-adjustable gun barrel having a nozzle at one end.
The apparatus includes a first 90.
degree.
elbow having one leg fixedly attached to the said pipe, a second 90.
degree.
elbow having one leg attached by a swivel joint to the other leg of the first elbow, and a third 90.
degree.
elbow having one leg attached by a swivel joint to the other leg of the second elbow.
More specifically, a fitting is provided having one end fixedly attached to the other leg of the third elbow and having its other end fixedly attached to the inlet end of the gun barrel.
The center line of the barrel lies in a plane passing through the axis of the first-mentioned swivel joint.
More specifically, the axis of rotation of the second swivel joint is horizontal to allow the barrel to swing in a vertical plane and the axis of the first swivel joint is vertical to allow the barrel to swing about the vertical axis.
The vertical plane of swing of the barrel passes through the vertical axis of rotation, so that the nozzle reaction force produces a zero force couple about the third vertical axis.
This apparatus is attached to the rotating body of the first turret with both vertical axes parallel and in line with each other.
The horizontal axis of both turrets are parallel to each other.
