ABSTRACT:
A Fire Hose Clamp is disclosed, this clamp being comprised of a shaft with a first jaw rigidly projecting from a first of its ends; a second jaw opposing the first, slidably mounted on the shaft between the shaft's first and second ends; a lever arm pivotally affixed via its first end to the shaft's second end at a first joint; and, a pitman having a first end pivotally affixed at a second joint to the lever arm between the lever arm's first and second ends, the pitman having a second end pivotally affixed to the second jaw at a third joint. Movement of the lever arm toward the shaft's first end causes the jaws to occlude.
