UNITED, STATES PATENT OFFICE Barry Lee ifiiffiigeles, Calif. pp ca on Novem r(1c;.1299;1z6) o.
(Granted under the act of March 3, 1883, as
amended April 30, 1928; 370 0. G. 757) This invention relates to an improvement in fog nozzles and is especially adapted to fighting fire. Fog nozzles constructed to divide the water into drops of so small a size as to approximate fog are known, also nozzles of general use which rely on rotating deflectors areknown. Fog nozzles now generally in use rely upon the pressure of the water forcing the water through many small orifices. This requires a pressure of about 100 pounds per square inch and further necessitates straining the water to prevent foreign matter from fouling the orifices. Moreover this nozzle can not discharge saponaceous compound.
This invention has for its object to provide a fog nozzle which is eflective throughout a wide range of water pressure, is free from danger of clogging, is capable of spraying saponaceous fire extinguishing liquids and other objects which will appear from an examination of the following description and drawings wherein:
Fig. l is a end view partially in perspective of the nozzle.
Fig. 2 is a side view along section A--A, Fig. 1.
3 is a sectional view of a detail of the structure.
Referring to the drawings wherein like numerals refer to like parts: The nozzle consists of a body I threaded at 2 for connection with a hose or applicator pipe. The opposite end of this body is closed at the forward end 3 except for a series of integralorifice spouts 4 arranged in a circle concentric with the body. These orifice spouts diverge from the longitudinal axis of the body at an angle of approximately 30. Any convenient number may be used but eight are preferred for effective operation and these should be at least in diameter to permit the passage of saponaceous compound. The forward end of the body is formed to provide a boss 5 on the center of the forward face which is threaded at 6 to receive the threaded spindle stem. The rotor 8 which is spaced from and overlies the orifices in the spouts is mounted for rotation on the spindle I and rotates under impact of water discharged from the orifices. The blades 9 of the rotor are set at an angle with the radius and at an angle other than 90 with respect to the plane of rotor, that is, the blades slope toward the body at their outer ends, and
the rotor to fit the spindle l and a duct II in the spindle, Fig. 3, to supply water from the body of the nozzle and discharge it between the spindle and bushing. A guard 12, secured to the body, surrounds the rotor to protect it from damage.
The device according to this invention may be made in a number of sizes, one of these is adapted to fit a one and one half' inch hose. The operation of this unit is outlined in order to afford a better understanding of the invention. The hose, or applicator pipe, is attached in the usual manner. Water is turned on, and the eight streams all impinge on the rotor which by reason of this multiple jet action is set in motion. The rotor operates at a high rate of speed and cuts the jet into fine particles or fog.
A unit constructed according to this invention with the spout orifices of an inch in diameter and the body resigned for attachment to a 1% inch hose, was tested with salt water at Fahrenheit while positioned five feet above and parallel to a horizontal flat surface with the following results:
