7 Claims.
This invention relates generally to a nozzle for the purpose of extinguishing fires with a liquid such as water, and more specifically to a nozzle of the type in which the liquid or water leaves the nozzle in several streams that are so directed as to impinge against each other to break up the liquid.
One of the objects of this invention is to provide an improved nozzle that is adapted to provide various spray patterns from a wide fanshaped fog or spray of limited relatively short projection to one in which the projection is materially increased and in which the pattern is narrower.
Another object of the invention is the provision of an improved fog forming nozzle adapted to caus different types of fog to be projected therefrom in which the shape, Velocity, and density can be changed as desired, and which fogs or types of fogs are made up of substantially uniform sized evenly distributed particles of moisture.
Another object of theinvention is the provision of an improved fog forming nozzle that is adapted to form different fog or spray patterns as desired by the operator without substantially changing the volume of water or liquid discharged from the nozzle.
An additional object is the provision of a nozzle holder and fog forming nozzle, and which holder is provided with a plurality of passageways having discharge openings in which said nozzle is adapted to be fitted and held by improved means independently of threads and the like.
HeretOfore fog nozzles of various intricate kinds have been produced, some having elongated stems operating through discharge orifices, and others having fixed angularly directed orifices for causing impingement of streams of water at a fixed point. Apart from the relatively expensive structure required in the former of the above types, the fog patterns are not as satisfactory as is desirable, and the volume ordinarily changes with changes in fog patterns, and also debris or impurities in the water quickly impair their efficiency. Also their operation is relatively awkward and slow generally requiring the rotation of a substantial portion of the nozzle about the longitudinal axis thereof in one direction or the other.
The main objections to the nozzles having fixed angularly directed orifices is that the entire nozzle must be changed to produce desired changes in patterns. By the time such change is effected the character of the fire may change and the substitution is no longer desirable.
With my nozzle structure the same nozzle is adapted to be quickly adjusted to meet any change in the character of the fire and is adapted to be used in fighting different types of fires with maximum eificiency in each instance.
Other objects and advantages willappear in the drawings and in the specification.
In the drawing, Fig. 1 is a sectional view through my improved nozzle showing it in position in a holder that is provided with controls.
Fig. 2 is a plan view of the nozzle of Fig. 1.
Fig. 3 is a side elevational view of the spray nozzle detached from the holder as seen from the-far side of Fig. 1.
Fig. 4 is a fragmentary elevational view, par.- tially broken away, showing the gear connection between the valve elements in the spray nozzle.
The fog nozzle of this invention is preferably separable from a control element such as a main nozzle, although it may be integral therewith as indicated in my co-pendin-g application, Serial No. 452,581, filed July 22, 1943 which has matured into Patent Number 2,342,050.
In the drawing herein I disclose a main valve body, holder or connector I that has a passageway 2 therethrough controlled by a valve 3. Also the particular valve body shown herein has a second passageway 4 that communicates at one end thereof with the first. A valve 5 is in said second pasageway, and both the first and second passageway have an internally threaded common inlet 6 for connection with a hose, or the like.
My fog nozzle may be formed to be directly connected with a. water conduit, or it may have a cylindrical portion 1 adapted to removably fit in the outer end of either passageway 2 or 4. One outer side of said cylindrical portion may have a pair of outwardly opening grooves or concave recesses 8, 9 therein extending transversely across said portion. Also a locating pin in may project from one outer side of said cylindrical portion at a predetermined point relative to said recesses. A pair of parallel shafts H, H are rotatable in said body I and extend transversely of passageways 2, 4 but between them. These shafts may be cut away at one side, as at I3, thus making them substantially half-rounds at the points where they cross the passageways. These half round portions are so positioned that the cylindrical portion 1 of my fog nozzle may be freely slipped longitudinally thereof into the outer ends of either of said passageways when the fiat sides venient, but the one that is of the shafts are facing said passageways. However once the said portion 1 is in place with its outer end in tight contact with a shoulder-supported gasket M in either passageway, a rotation of the shafts will result in the half round portion on shaft H or |2, as the case may be, rotating into recess 8 or 9. Thus the fog nozzle will be securely held in whichever passageway its cylindrical end is positioned.
The shaft II is adapted to fit in recess 8 when portion I is in passageway 2, while shaft l2 is adapted to fit in recess 3 when portion I is in passageway 4, as is shown in Fig. 1.
The shafts |2 may be connected at one of their ends by intermeshing gears |5 secured thereto respectively (Fig. 2) and one of said shafts may project through a gear retaining plate l6 secured to body for carrying a manually actuatable handle H for rotating said shafts.
The cylindrical portion 1 of my fog nozzle is integral with a main body and a passageway 2| extends through said portion 1 and body 20.
In body 20 said passageway is enlarged as at 22 and it opens outwardly of body 20 at the side of said body opposite portion 1.
A pair of cylindrical members 23, 24 are rotatably supported in body 20 in position alongside each other with their axes parallel and extending across the discharge end of the enlarged portion 22 of passageway 2|. A rib 25 integral with body 20 and concave on opposite sides for fitting against adjacent sides of members 23, 24 may extend between said members to space them and to form part of the bearings therefor, while the opposed sides of the main passageway may be concave, as at 26, for fitting against the opposite outwardly facing sides of said pair of members.
Each of the members 23, 24 is formed with a cylindrical bore 21 of the same size extending transversely therethrough, one end of each such bore communicating. with the enlargement 22 in passageway 2|, while their opposite ends open outwardly of body 20.
The opposite ends of members 23, 24 may be journaled in the body 20. A pair of intermeshing gears 28, 29 or gear segments (Fig. 4) are respectively secured to one of the corresponding ends of each member for rotation of said members simultaneously to the same degree upon rotation of either one of said members. The member 24 may have an axial extension 30 at its end opposite the gears, and which extension is secured to an operating handle 3| that is outwardly of body 20 but closely adjacent thereto. Suitable packing 32 (Fig. 2) may form seal between said extension and the body to prevent leakage, and a gear plate 33 may be secured by any suitable means to body 20 in position covering gears and also preventing leakage. Of course either member 24 or 25 may be extended for carrying handle 3| according to which is found to be most connot so extended is fully enclosed within body I so that a single packing 32 together with plate 33 will be all that is required to form a tight seal at the ends of said members 23, 24.
The handle 3| is adapted to be moved in an are between spaced pins 34 (Fig. 3) projecting from body I. Friction means comprising a spring urged pin 35 (Fig. 2) carried by handle 3| and recesses 36 (Fig. 3) formed in the body in the path of the outer end of said pin, is provided for holding said handle (and members 23, 24) in any desired position as the handle is moved between pins 34 The members 23, 24 may be substantially set in the positions shown in Fig. 1 when handle 3| is against one of the pins 34, and in which positions their axes will intersect at point 35 closely adjacent the body 20 and which point may be on a line 36 parallel with the longitudinal axis of passageway 2|. In this position streams of water ejected from said bores will impinge at point 35 and a wide fan shaped fog or spray of limited projection is produced. As the handle 3| is moved toward the opposite pin 34 the axes of bores 21 will successively intersect at points on line 36 outwardly of body 20, as at points 31, 38, etc., and which points are substantially equally spaced from each of the members 23, 24. As the angles between the intersecting axes or impinging streams become more acute, the velocity of the spray produced is increased, hence its projection is greater. Likewise the pattern of the spray or fog is narrower. It will be seen that by continued rotation of members 23, 24 until their bores are substantially parallel, the density of the ejected streams becomes greater until practically a pair of solid streams is produced, and all through these changes there is no restriction in the volume of water conducted through bore 21 and discharged therefrom.
From the foregoing it will be seen that an operator can instantly procure any desired fog or spray pattern desired for the particular fire, or to meet changes in the characteristics of a fire, or to protect himself in an unexpected emergency.
The valves 3, 5 in the body |,-where such body is used, enables the operator to control the volume of fiow to said bore 21, and by closing valve 5 and opening valve 3, a solid stream may be ejected from bore 2. Handles 40, 4| may be provided for manipulating valves 3, 5, respectively.
