Application January is, 1952, Serial No. 266,542
This invention relates to improvements fin combined fog and solid or straight stream nozzles for the hose of fire-fighting equipment. More particularly it provides such anozzle wherein two separate streams pass throughthe nozzle from a shut-oft" valve to'the delivery end of the nozzle, with one stream extending axially through the nozzle for delivering a solid or straight stream of water therefrom, and with the other stream annularly surrounding the. axial stream within the nozzle and leading to fog-producing means at the discharge end of the nozzle at which fog is generated and dispensed forwardly and outwardly around the straight stream. i i
The fogproducing nozzle has become a generally accepted unit of fire-fighting equipment, having particular advantage over sprays and straight streams in repelling smoke and fumes, and absorbing heat, as firemen advance toward a fire through rooms and halls which may be filled with smoke and fumes. But, for actual extinguishment of a fire, a straight stream is essential and, so far as we are aware, two separate types of nozzles have been required heretofore, a fog-producing nozzle to protect the fire men advancing toward the flames, and a solid or straight stream nozzle for use inextinguishing the fire.
Various proposals heretofore have sought to combine in a single nozzle a straight stream and a forwardly and outwardly directed spray, but the sprays have not been effective because they have been supplied from the main stream through the nozzle and have lacked the pressure and volume for the intended results. More important. however, is the fact that atomized particles of water dispensed as a cloud of fog i's definitely more efficient than any spray for repelling smoke and fumes. n
Hence, it is an object of the present invention to provide a combined fog-producing and straight stream nozzle wherein a fog-generating means at the delivery end of the nozzle is supplied with its own pressure stream of water arrangedannularly around the straight stream at the axis of the nozzlewhereby the pressure stream which is converted into fog is driven through the fog generating means unafiected by the adjacent straight stream. According to the invention, the supply stream of water coming to the nozzle is divided at the shut-oii valve: of the nozzlawith the major part of the supply stream passing axially for constituting thestraight stream issuing from the nozzle, and with a substantial portion of the supply streampassina through an 3 Claims. (o 299-139) annular passage extending from said valve to the "discharge end of the nozzle, at which location it is driven through atomizing means which discharges a spreading cloud of fog or vapor around 7 the issuing straight stream of water.
- Another object is to provide a combined fogproducing and straight stream nozzle wherein fog-generating means at the discharge end of the nozzle is supplied with its own pressure stream (it water driven through the nozzle in general parallelism with a main straight stream of water passing axially through the nozzle, with manually operable means for stopping the issuance of fog from the nozzle at will without appreciably affecting the straight stream of water issuing axially from the nozzle.
I It is, moreover, our purpose and object generally to improve the structure and effectiveness Fig. l is a side elevation of a nozzle embodying features of the invention, it being shown connected to a hose and discharging bpth a straight stream of water and a protective cloud of fog; f'Fig. 2 is a longitudinal cross-sectional view of the nozzle of Fig. l, on a larger scale;
., i Fig. 3 is a view, partly in cross-section, of the right-hand end portion of the nozzle of Fig. 2 tiirned about its axis through ninety degrees, and showing the cut-oil valve shifted to its closed position;
Fig. 4 is an elevational view of the left-hand portion of the nozzle of Fig. 2 turned about its axis through ninety degrees; and
Fig. 5 is a cross-sectional view on line 5--5 of Fi 4.
Referring to the drawing, the nozzle In of Fig. l is shown connected to a hose l2 and is discharging both a straight stream M of water and a protective cloud ll; of fog or vapor.
The connected end of the nozzle has the interiorly threaded opening I8 for reception of the standard threaded end or nipple of the hose l2. A relatively short smaller diameter passage 20 leads axially of the nozzle from the opening 18 to a valve 22 which is rotatably mounted within the body :of the nozzle a substantial distance from the delivery end of the nozzle, and a longer axial passage 24 extends from the opposite side of valve 22, or from a location adjacent the valve, to and through the delivery end of the nozzle, this latter passage 24 having suitable uniform or their bearings, and a yoke type actuating handle 36 has its spread arms 38, 40 rigidly connected to the projecting ends of the trunnions 28,-. 38" re spectively, whereby the valve may be actuated by handle 36 between its open and closedpositions of .Figs. 2 and s. A passage c2 throd'ghthevalye connects the axial passages 20 and 2 when the valve is open, as shown in Fig';-2i-. i According to the invention, valve 22 has oppo site side portions of thesphere cut away in the parallel planes 44, 45 in Fig. 2, which are also parallel to the axis of the trunnions 28,58. The p'larieB is closer to the parallel plane of the axis of the trunnions than is the plane M; and the passage 42 through the valve has gradually increasing diameter from the annular edge of the valve in plane 46, to the annular edge of the valve in plane 56. Hence; the outlet end of the valve passage 52 is substantially greater in diameter than the diameter of the nozzle passage as, whereby'a substantial portion of the water coming through' the valve delivers directly into an annular passage 48 which surrounds the axial passage 2 This water may enter the passage 48 through an annularly' arranged series of openings 5B. V
Preferably, a manually operable means ispro vided for closing the dis harge end portions 52', 54 'of the passages 52; 54 when it is desired to stop the generation and dissemination of fog without materiauy affecting" the straight stream l4. As herein shown, a cap 56 fits nicely and rotatably over the discharge end portion of the nozzle Hi; the cap having an axial opening 58 therein which leaves the axial passage 24" unobstruoted in all positions of the cap. A series of perforations 6B are arranged annularl'y around a 4 ble rotational movements thereof between open and closed positions of the cap.
It is intended that the patent shall cover, by suitable expression in the appended claims, whatever features of patentable novelty exist in the invention disclosed.
