1. A fire fighting monitor comprising:
- a first pipe having an inlet and an outlet, said first pipe having a passageway with a central axis, said passageway extending from said inlet to said outlet, said passageway having a curved portion wherein said outlet directs the flow of fluid in a direction angled to said flow of fluid into said inlet; and
a second pipe mounted about said outlet of said first pipe, said second pipe pivotally mounted by at least one pivot along a pivot axis, said pivot axis being located at said outlet of said first pipe, and said second pipe having an outlet in fluid communication with said outlet of said first pipe and being pivotal about said pivot axis over a range of motion greater than 90°
;
wherein said outlet of said first pipe has a spherical body, and said second pipe including a spherical body for mounting about said outlet of said first pipe; and
a spherical body interposed between said second pipe and said first pipe.

Abstract
A fire fighting monitor includes a first pipe having an inlet and an outlet and a passageway with a central axis. The passageway extends from the inlet to the outlet and has a curved portion wherein the outlet directs the flow of fluid in a direction angled to the flow of fluid into the inlet. The monitor includes a second pipe mounted about the outlet of the first pipe, which is pivotally mounted about a pivot axis, which is located at the outlet of the first pipe. The second pipe also has an outlet in fluid communication with the outlet of the first pipe and is pivotal about the pivot axis over a range of motion greater than 90°.
