SPRAY-NOZZLE,
Specification of Letters Patent.
Patented Dec. 9, 1919.
Application filed March 23, 1918. Serial No. 224,127.
To all whom it may concern:
Be it known that I. HARRY 1): links, citizen of the United States, residing at River Forest, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spray-Nozzles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to spray nozzles, its general objects being to provide a simple and effective nozzle construction which will have inimum of separable parts, which will be likely to 010 which will always 'tain the spray-producing portion in proper operative position when the nozzle pailts'are assembled, and which will readlly permit a cleaning of the spray-producing parts and a removal of any foreign matter which might become lodged within the nozzle. More particularly, my inventlon aims to provide a spray nozzle compris ng only two sepaable parts (oneof which is attached to the fluid supply pipe while the other forms the nozzle proper) and in which the jet-producing core of the nozzle is rigidly connected to one of the said two parts, but so spaced from the part to which it is thus connected as to permit a speedy cleaning of all parts of the said core.
In making spray nozzles, it has hereto forebeen customary either to clamp a suitable core (often in the shape of a turblne or plurality of vanes) between'other constituent parts of the nozzle, or to} support such a core 'in operative position by means'of a screw extending through a surface portion of the nozzle. In either case, the core has commonly been housed entirely by the part to which it was secured, so that access to certain parts of the nozzle could only be afforded by first separating the constituent outer portions of the nozzle and then removing the core from one of these. In doing so, the core has been liable to damage through being dropped upon some hard surface, and where the core was fastened by means of a screw, this removal has involved the use of a tool and also the danger of dropping and losing the screw. So also, where the jet-directing portion has been threaded upon one of the casing portions of the nozzle. tools have been required for removing the. same to afi'ord access to all oper- 'a .'no iecore Iig 4 is n enlarged elevatio ftl of the nozzle and the portion carryingthe same, taken at'right angles to Fig.2.
Generally speaking, I accomplish the purposes of my invention by rigidly attaching the core to one of the two relatively separable parts which constitute the casing of the nozzle, in suitably spaced relation to the part to which it is attached; The separable parts of the casing desirably consist of a coupling 1 threaded at one end to fit the pipe through which the liquid for the nozzle is supplied, and equipped at its other end, as by a thread 2, for engaging the larger end of the tapered member 4 which constitutes the nozzle body., The core is desirably fastened to the extreme-end of the threaded portion 2 by means of legs 3 of such shape as not to interfere with the ready flow of liquid to the base end of the core, the object of these legs being'to space the base of the core sufficiently from the tip of the threaded portion 2 so that any convenient toolmay readily be passed transversely through the resulting arch for removing such foreign matter as may have become lodged there.
The said legs are also desirably so positioned as to coope ate with portions of the core in subdividing the stream of liquid into the desired number of' stream parts which the core is intended to produce, either for producing separate jets or for producing variously acting forces in a single jet or stream. Thus, the legs are shown in Figs. 3 and 4 as cooperating with the 'web 9 both in supporting the vanes, and in initially subdividing the stream of liquid and preventing the subdivided stream from rotating bodily before it reaches the vanes.
To enhance this action of the legs 3, I desirably form these from edge portions of a web 9 extending rearwardly from the helical vanes 10 and out or alinement with the recesses 11. These recesses cooperate with the sides of the web 9 in defining pas-- sages through which liquid is projected parallel to the axis of the nozzle, while a relatively greater part of the liquid has rotation imparted to it by the helical disposition of the rear surfaces of the vanes 10. Moreover, the web 9 prevents the column of liquid from being rotated bodily about the axis of the nozzle until it has passed along a considerable portion of this web, thus cooperating with the recesses 11 in imparting different rates of spiral advancement to different parts of the stream, which different tendencies cause part of the liquid to move radially inward of the nozzle and hence produce a solid stream of liquid within the tapering nozzle casing. The use of formations on helically vaned nozzle cores for this general purpose of producing an imperiorate spray has been more fully described in U. S. Patent #1282175, issued to me October 2-2, 1918, on spray nozzles. My "present invention distinguishes from what was there disclosed both in the method of supporting the nozzle core and in employing a web back of the helical vanes, and in likewise employing legs connecting the core to a part of the nozzle casing, for cooperating with the formations on these vanes in producing the desired result.
hen thus constructed, it will be obvious from Fig. 3 that when the nozzle body 4. is screwed upon a thread 2 of the base member of the device, the core is automatically brought into its proper operative position, without requiring any added manipulation or use of tools. Indeed, the detachable or tip member of the nozzle equipped with wings 8, so that this portion can easily be screwed into proper position, or unscrewed from the latter, without the use of any tools. When this member is unscrewed and detached, its bore is entirely open for inspection and cleaning without the prior removal of any parts from the same, as the core then is presented as in Fig. 4., thus permitting a ready inspection and cleaning of all parts of the core. Moreover, bv providing legs 8 of suitable lengths I can readily permit access not only to the base of the core, but also to the interior of the nozzle member 1. Consequently, I not only aiiord large effective openings at the connection between the core to the liquid inlet member 1, thereby reducing the chance of having any foreign matter clog the core, but also permit such speedy access to all operative positions of the nozzle that the removal may desirably be of scale or any other needed attention can be effected in a small fraction of the time heretofore required.
However. while I have illustrated my invention as including a stream-rotating core of a turbine type, which core may desirably be or the form shown in U. S. Patent No. 1282175, as issued to me on October 22, 1918, and as having this core attached to the coupling member 1 of the nozzle, I do not wish to be limited to this or other details of the construction and arrangement above described. Moreover, many changes might be made without departing from the spirit of my invention, it being obvious that according to the same the core is attached to one of the two members comprising the casing of the nozzle, and is normally housed by the other member, the shape of the different parts being such as to produce the desired cooperation of the core portions with the tapering casing portion in producing the desired shape and consistency of spray.
I claim as my invention:
1. In a spray nozzle, an imperforate core including a plurality of substantially helical vanes each having a recess at its forward edge for permitting the passage of liquid therethrough at a greater rate of spiral advancement than that which the rear face of the vane tends to impart to the liquid, and a support for the core including portions respectively back of the vanes and disposed for preventing the bodily rotating of the initial stream of liquid, whereby the said portions of the support cooperate with the said recesses in modifying the rate of spiral advancement of difierent portions of the liquid.
2. In a spray nozzle, an imperforate core including a pair of substantially helical vanes having formations for modifying the rate of spiral advancement of part of the liquid, and a web extending rearwardly from the said vanes and initially subdividing the stream of liquid and deterring a bodily rotating of the liquid.
3. In a spray nozzle, an imperforate core including a air of substantially helical vanes having formations for modifying the rate of spiral advancement of part of the liquid, and means connecting the core toa ortion of the nozzle casing and cooperating with the said formations in modifying the rate of spiral advancement of part of the liquid and thereby producing an impertorate spray.
