Jime 8, 1943.j A. F. DE LA cALLE 2,321,017 I FLUID DISQHARGE NOZZLE Filed Oct. 51, 1940 INVENTOR Patented June 8; 1943 UNITED STATESQQPATENT OFFICE.
FLUID DISCHARGE NOZZLE zles, and particularly to devices of this type and kind for use in dispensing various viscous and carbonated fluids which are susceptible to the formation of foam upon the discharge thereof into a, receiving receptacle, but more particularly the invention relates to nozzles adaptable for use in the discharge of draft beer; and the object of the invention is to provide a nozzle having means for spreading the fluid or liquid in thin flhn-like layers facilitating the quick and easy breaking up of the gas bubbles and thereby substantially eliminating the formation of foam in dispensing the fluid or liquid ina receptacle or container;
and with these and other objects in view, the invention consists in a device of the class and for the purpose specified,- which is simple in construction, efficient in use, and which is constructed as more fully hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which:
Fig. l is a longitudinal sectional view through one form of nozzle which I employ.
Fig. 2 is a section on the line 2-2 of Fig. 1.
Fig. 3 is a view similar to Fig. 1 showing another adaptation of the invention.
Fig. 4 is a view similar to Figs. 1 and 3 showing another modification.
Fig. 5 is a section onthe line 5-5 .of Fig. 4; and
Fig. 6 is a view similar to Figs. 1, 3 and 4 showing another form of construction.
In dispensing liquids or fluids of various types and kinds, as for an example in dispensing draft beer, the formation of excessive amount of foam inthe receiving receptacle has caused considerable waste, inconvenience and moreover, considerable delay in service by reason of the necessity of having to refill the glass or receptacle into which the beer has been dispensed. It is the object of my invention to provide a discharge nozzle for various types and kinds of foam-forming liquids or fluids to eliminate the objectionable features in the formation of such foam. In this connection, it must of course be understood that in the service of beer, the presence of a little foam, commonly referred to as "a head on the beer, would be desirable, but this can be adjusted by the use of a nozzle which will control, by reason of its discharge passages, and film guiding surfaces, the amount of foam to be collected in a receptacle of predetermined size.
In the accompanying drawing, a few adaptations of the invention are disclosed, and in 1 and 2 is shown at l0 a discharge nozzle comprising a large casing portion ll having-contracted upper and lower ends I2 and 13. The end- I! terminates in a suitable pipe connection I4,
whereas the end l-3 terminates in a discharge spout l5. The nozzle ll] is of a built-up construction as will be apparent. Arranged in theupper end portion of the casing l' l adjacent the contracted portion I2, is a cup-shaped member Hi, the depending side walls ll of which are ar ranged in spaced relation to the walls of the casing H to form a narrow or restricted discharge passage [8. The cap I6 may be spaced in the casing by'a series of ribs l9, note Fig. 2, which are welded orbrazed in position, or any other method may be employed for spacing the cap l6 and securing the same in the casing. 7 With the construction shown in Figs. 1 and 2 the fluid to be dispensed through the nozzle or discharge ID will be guided as a thin layer or film along the inner surface .I la of the casing ll, thereby allowing the gas bubbles or at least the majority of these gas bubbles to break up and be discharged from the fluid; thus ellmi-' hating to a major degree, the formationof foam in a receptacle in the discharge .of the fluid from the spout end I 5 thereof. v
In Fig. 3 of the drawing is illustrated another adaptation of the invention In this structure the nozzle Illa comprises an elongated tube 20 beveled at its lower end as seen at 2| in forming the discharge spout. Arranged upon the :upper end of the tube 20 is a coupling or header 22 in which the tube 20 is secured in the-same manner as attaching the cap IE to the-casing l l in Fig. 1. Within the tube 20 is arranged'a cap 23-similar to the cap It, thus forming in the resulting nozzle structure an inner thin discharge passage 24 similar to the passage l8, and an outer discharge passa e 25. The header 22 also includes a pipe connection 26. u a
With the construction shown. in Fig. 3; it will be apparent that a thin layer or film of the fluid will pass downwardly over both the inner surface 20a and the outer surface 20b of the tube 20, thus increasing the volume of the fluid dispensed from a nozzle of predetermined tubular size. It will be apparent, however, that the discharge as at 25 may be dispensed with where the question of volume is not a factor.
In Figs. 4 and 5 of the drawing is shown another adaptation of the invention wherein the nozzle Illb comprises a coupling end or header 2'! having a pipe connection 28. Within the header adjacent the discharge end thereof is disposed a grating 29 which forms a series of parallel openings 30, note Fig. 5. longitudinally of these openings are a series of depending nozzle plates 3i which form between. the opposed walls of the openings 30 and side walls of the header 2'], a series of thin discharge passages 32, as is noted in Fig. 4 of the drawing.- These passages will guide the fluid or liquid in the nozzle plates 3|, as will be apparent. It will; also be understood that while the contour of the nozzle as shown in Figs. 4 and 5 of the drawingj is represented as rectangular rather than round this has been done simply to show that the par-1 1L5} ticular cross sectional contour of the nozzle mayi be varied. However, the same principle of con-i struction shown in Figs. 4 and 5 is applicable tol nozzles of any cross sectional form.
In Fig. 6 of the drawing is shown a iurthen' zoj tively large surface, the film or fluid may also be guided over a relatively restricted surface, such for example as rods or wires. In this construction, iilc represents the discharge nozzle comprising a casing 33 having a contracted end 34 terminating in a discharge spout 35; the upper end36 of the casing being closed and having a pipe coupling 31. Within the casing 33 is arranged a cap 38 of the general construction of the cap l6 and positioned to form a' discharge passage 39 between the periphery thereof and the inner surface of the casing 33, so that in this respect, the structure will operate substantiallysimilar to the structure shown in Fig. 1. However, the structure is modified by providing in the "top Wall of the cap 38, a plurality of apertures 4|] which may be arranged in any desired manner. Arranged in these apertures and extending downwardly through the casing 33, in the manner illustrated,'are a plurality of rods, wires, or the like 4! which are spaced from the walls and the apertures 40 so as to provide for the collection of a'film or layer of the fluid around the wires or rods 4| for the purposes stated. The wires or rods 4! are supported in connection with a plate 42 arranged above the cap 38 and supported in the casing 33 in the same manner as supporting the cap 38 therein, or'in other words, in the manner of supporting the cap IE, to pro vide passages 43 at the periphery of the plate 42 so as to allow the fluid to extend to the apertures 40 as wel1- as through the passage 39. 1
From the teachings in Figs. 4, 5 and 6, it'will be'apparent that by controlling the amount of surface over which a fluid may pass through the nozzle, the volume of fluid to be discharged through the nozzle can'be controlled and at the same time the degree of foam elimination can also be controlled. It willalso be apparent that the length of the various nozzles may be modified to suit different adaptations of the invention.
From the teachings in Figs. 4, 5' and 6, it will Supported centrally and erally speaking, the discharge devices may be said to comprise means for guiding a fluid in thin layers or films, thereby breaking up gas bubbles in the fluid prior to discharge of the fluid into a receiving receptacle and eliminating excessive formation of foam on the fluid dispensed into the receptacle.
Having fully described my invention, what I claim as new and desire to secure by Letters thin layers or films upon both side surfaces ofi l1 Patent, is:
1, A nozzle of the class described for discharging foaming liquids, 'said nozzle comprising a header having an inlet passage and a plurality of restricted outlet passages, means associated with said outlet passages for conducting discharged liquid away from said passages, said discharge passages being circumferentially arranged in said header, said conducting means comprising a tubular member extending from said passages, and said header having other circumferential passages arranged concentrically to said firstnamed outlet passages, said concentric passages registering with opposed surfaces of said tubular-memberpthereby' providing for the discharge'of fluid on both inner and outer surfaces of said member J V t i 2. In a nozzle of the class described having-an inlet passage and a tubular body forming a discharge passage, means associated With'sai'd tubular body for spreading a discharged fluid in a thin film on the walls of said tubular body, thereby providing for the liberation oi free gas bubbles from saidfluid, said last-named means compris ing a shallow cup-like member secured tosaid tubularb'ody and spaced therefrom suflicieritly to provide a narrow'annular discharge passage between said tubular body and cup-like member, said'cup-likevm'ember comprising a'. header arranged outwardly of said tubular body and-hav'- ing an enlarged passage forming the inlet passage of .said nozzle, and said nozzle including another cupelike member arranged inwardly of and in closely spaced relation tosaid tubular body, thereby-providing for the discharge of fluid along both inner and outer surfaces-of said body. 1
