NOZZLE Filed March 4, 1944 ilmwyfw ATTORN EY Patented Nov. 6, 1945 r NOZZLE Lewis G. Morris Timpson, Plainfield, N. J.
Application March 4, 1944, Serial No. 525,066
2 Claims.
The present invention has for an object to provide an improved nozzle for use in producing and delivering fire extinguishing foam.
Another object is to provide a nozzle suitable for production and use in very small sizes. And another object is to provide a choice of type and quality of eiliuent most suitable to the peculiarities of the fire at a given moment.
The nature and object of the invention will be better understood from a description of a particular illustrative embodiment thereof for the purposes of which description reference should be had to the accompanying drawing forming a part hereof and in which Figure 1 is a central sectional view of a foamforming nozzle embodying the principles of the invention.
Fig. 2 is a plan view of the same.
Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1.
Fig. 4 is a longitudinal section of another form of nozzle and Fig. 5 is a sectional view taken on the line 5-5 of Fi 4.
The basic elements of these nozzles are taken from the old art of aspiration nozzles and in particular from nozzles of the type wherein large volumes of gases are educted by small volumes of liquid under high pressure. These foam nozzles shown for the purposes of illustration provide for thorough incorporation of the gas within the liquid mass and provide adequate means to recover some of the kinetic energy of the supply stream in the form of pressure energy.
The nozzle 5 as shown in Figs. 1, 2 and 3 is designed to receive foam-forming liquid under pressure and to cause aspiration of the liquid to provide air foam and to project that foam with suitable force. As shown, the rear or base portion 0 is formed for connection to a liquid supply hose 1 and the forward tapered convergent nozzle portion or collector element 8 forming an aspirating chamber 9 is also so formed that 3168.11 be connected to a delivery hose if desired.
The aspirating chamber of the nozzle is designed to receive foam-forming liquid entering as a spray under pressure and to allow aspiration of the atmosphericair and consolidation of the two fluids. The design is such as to recover suitable pressure to project the resulting foam to the required distance and in the required quality.
Between the inlet of the nozzle and the aspirating chamber 9 a spray-forming arrangement is provided having two angularly related passages lO-HI meeting at an angle of about 60 degrees to effect a vigorous impingement of two liquid streams upon each other. In front of the point of impingement a cylindrical baifie member or spray straightener l l is provided which serves to confine the spray and to break up larger drops or streams and thereby greatly increase the surface area of the liquid to achieve a high volumetric aspiration of the gas. The stream of spray passing forward is well adapted for aspiration by air entering a series of holes I 2 in the side of the nozzle. In order that the spray shall not exit through the holes I! they are so positioned that all drops driving forward from the point of impingement of the two streams in the passages Iii-l0 which do not impinge against the baflle will pass beyond the air inlet holes before striking the wall of the nozzle.
The size of the passages l0-lll is suitably proportioned for the size of the nozzle and the rate of flow of the liquid. The present invention compensates to a large extent. for such defects of manufacture in the smaller sizes as burrs, rounded edges and the like and for imperfections incident to usage such as corrosion and adherence of small particles by the provision of the protective baflie ll interposed between the point oi formation of the spray-like jet and the point of aspiration in the chamber 9. The baille will reform elements of the spray which by faults of the nozzle have motion other than substantially forward.
Nozzles of smaller sizes can be used satisfactorily with double acting hand pumps. These nozzles do not give a constant pressure supply and the design of the nozzle may be varied to provide the best aspirating eiiiciency for a par ticular pump and the pressure available.
The ratio of contraction of the collector portion of the nozzle is about 4 to 1. The base or handle 8 has a forward protective ring I! spaced outward from the body of thenozzle and extending far enough forward with relation to the air inlet holes I! to prevent the holes from being accidentally closed by the hand of one using the nozzle and yet the holes freely admit air.
Variation in operation of the nozzle is aiforded by the arrangement shown in Fig. 1 in that the impingement spray-forming passages ill-4t are carried in a rotatable valve member l6 which also has a passage l'l straight through at a right angle to the plane of the impingement passages lO-IU. The valve member can be rotated for use to provide either a foam-producing nozzle or to provide a nozzle throwing a substantially solid stream. The eilluent 01' the solid stream will still cause aspiration to a certain extent and will therefore have some foam-like quality with corresponding fireextinguishing value, and in addition the stream will have the oil-wetting power of the chemicals generally used in foam production. It will have a distance throw substantially equal to that of the usual water stream.
In many instances in the attack upon a serious oil or gasoline fire this choice of eflluent will have great value. Many of these fires are of such extreme intensity that approach to them sufiiciently close to apply conventional foam is impossible but the use of the substantially straight jet makes it possible to subdue the fire to such a degree that later approach for the final smothering operation will be quite feasible. At other fires splashes of some violence of a foam-like efiluent are desirable to reach around walls until such subduing of the fire as will allow the conventional foam to be applied. These features of combat have particular value on ships and in crowded structures.
The nozzle shown in Figs. 4 and 5 is similar in principle to that described above.
The handle or base member 20 is formed for convenient attachment to a small hose 2|. The base is threaded to receive the collector element 22 between the end of which and a shoulder of the base member a combined spray-forming element and batlle member 23 is secured. A rubber washer 24 insures a liquid-tight joint. As in the embodiment of Fig. l the base member is formed with a protective ring 25 which projects over the eight or more carbon atoms, and various solubilized proteins are also suitable. A solvent may be demanded by the conditions of service.
It will be understood that the foregoing description of particular embodiments is illustrative merely and is not intended to be construed as defining the limits of the invention. Various modifications and adaptations may be made without departing from the spirit of the invention as defined in the appended claims.
I claim:
1. A foam-forming nozzle of the character described having a plurality of forwardly directed jet-forming passages entering the rear of the nozzle at an angle to one another so as to bring a plurality of entering liquid jets into the nozzle in impinging relation one to another to form spray, lateral ports in the side of the nozzle relatively close to the position of entrance of the Jets, a rotatable transverse valve member through which the jet-forming passages pass whereby rotation of thevalve member will vary the spray formed, and a cylindrical baiiie within which the spray is formed and by which it is confined.
2. A foam-forming nozzle of the character described having a plurality of forwardly directed jet-forming passages entering the nozzle at the rear at an angle to one another to bring a plurality of entering liquid jets into the nozzle in impinging relation to form a fine spray, a cylindrical baflle surrounding the position of impingement and extending forwardly to confine and direct the spray, and lateral ports in the exterior nozzle wall outside of the baflie for admitting air to the spray but so positioned relative to the baflle as to be protected from the spray formed within the baflle substantially as and for the purpose described.
