Abstract: A peripheral jet fire fighting fog nozzle having mounted on the discharge end thereof a stream-shaping sleeve provided with a convex end face adapted to form an open outer cone-like spray pattern and a plurality of circumferentially spaced fog teeth extending axially from the convex end face with axially extending convex lateral surfaces on the teeth adapted to spread the spray pattern laterally and fill in the lateral opening or gaps in the outer spray pattern. Rounded axially extending inner end surfaces provided on the fog teeth together with adjacent lateral surfaces of the fog teeth are adapted to form uniform droplets which are uniformly distributed within the interior of the outer conical spray pattern to form a uniform conical spray pattern which has a wide angle of divergence and is free of circumferential gaps.

Abstract: A flow-control valve assembly particularly useful in fire fighting apparatus comprising a contoured valve seat mounted axially within a valve body and a balanced tubular valve member reciprocably movable in the valve body coaxially with said valve seat for providing proportional flow control, manual valve actuating means for reciprocably moving the tubular valve member including a disc rotatably mounted in a bore formed in a lateral surface of the valve body on a pivot member on which a handle is pivotally mounted and a pin spaced from the pivotal member extending through the handle and the disc which engages in a circumferential groove formed in the outer surface of the tubular valve member for effecting reciprocable movement of the valve member when the handle is reciprocably moved. The disc can be made of deformable material and provided with means for expanding the disc to impart a braking action on the movement of the handle.
