SPLINED DIFFUSER NozzLE Filed June 30, 1947 2 Sheets-Sheet 1 N2 u I 1MM mi WWA/2%- June 13, 1950 Filed J'une 30, 1947 R. J. PAGLIUSO.
SPLINED DIFFUSER NOZZLE 2 Sheets-Sheet 2 lwentor,
silient cushion ring 5c which is sunk in the bore of the body 5, and after the nut I has set the ring 5p to the desired degree of frictional resistance on the ball then the nut is locked by a set screw ls. This will keep the ball resistance constant.
The outer or forward end of the body 5 has a reduced, conical nose l8 onto which is snugly, concentrically fitted a truncated conic tip member or diffuser 9 which is removably fixed, by an axial screw Ill, on said nose. Port holes II in the body discharge water radially to the space X back of the rear end of the diffusing tip.
Referring no-w more particularly to the tip 9, its periphery is provided with laterally spaced, longitudinal, splineway channels I3 between longitudinal teeth |315, Figs. 3 and 4. A distinctive feature of channels I3 is that whatever may be the cross-section form of these channels their bottom or root faces converge toward the tip axis and they, the channels, extend axially for the full length of the conical face of the tip, irrespective of the pitch of the tip conically. This `annular system of longitudinal channels-hereinafter called splineways-form at least a part of the outlet of the nozzle from the chamber X. Fig. 2 shows a root line A at a suitable angle from the `axis of the tip 9 and therefore determining the angle at which a jet of water will issue from its respective splineway I3, and it will be understood that a suitable number of these splineways may pitch at the angle A, for example, while others pitch on a different angle as indicated by the root line B, and in such an adaptation the different pitch splineways would be alternately arranged around the tip and therefore effect the discharge of systems of jets in conic showers of different pitch from the axis of the spray nozzle In orderto readily regulate the volume and the velocity of the jets from the several splineways I 3 between the teeth |315 in the tip member there is provided an external sleeve Valve I5 axially shiftable along and non-rotative on the body 5. The fore end of this valve is provided with an internal, annular system of keys or splines I4 which are complementary to and workebly t into the respective splineways I3, and have a ccnic pitch equal to their mating splineways and are of such depth that their ridge faces can shift into contact with the root faces of their splineways I3 and thereby shut on flow therefrom. In other words, 'the splines and their splineways are of equal depth, and the ridge faces of the splines and the root faces of the respective splineways are always parallel as clearly shown in Fig. 2, regardless of the relative positions of the sleeve valve I5.
From this it will be seen that as the valve I5 moved axially rearwardly from the closed position, Fig. 2, the splines recede from the roots of their splineways, first allowing fine, fast flowing ,iets to issue from the splineways and later, slower jets will issue. If all the splineways have the same conic, root pitch as A then one conic spray will be effected from the nozzle, but if the roots pitch on different angles it will be clear that common center, differentiated sprays of conic form will issue.
While the splines and the splineways may be formed directly in the material of which the valve member and the tip member are formed and while in such a case the splines would act as to wipe and clean the root and the ridge faces thereof and prevent solids from building up and choking the parts, it is preferred that the splines be of .a resilient or cushioning material such as hard rubber or the equivalent and that the splineways be formed of a stiffer, moldable material, such as an appropriate plastics body material. Therefore the tip 9 is here shown as of such a stiff material, while the fore end of the bore of the sleeve I5 is provided with an attached bushing I5b of the desired softer material.
Further, the valve I5 has a capacity for reces- `sion to such a position as will fully uncover the rim of the tip 9 so that any material that may chance to collect in the space X can be flushed out from time to time without need of dismounting or disassembling the nozzlean important advantage.
The rear end of the valve l5 has external threads I 8a and an inturned lug I5a which is shiftable along a shallow channel I6 therefor in the contiguous face of the body 5, in which is sunk an O-packing ring I1 on which the valve rides during its change of position. An external, nonshiftable, manually rotative actuating shell i8 lits the threads IBa of the valve and is retained against end shift on the body 5 by a stop shoulder 5s in cooperation with the properly adjusted nut l, supra.
In cases where so desired a jet of needle fineness may be had by suitable design 'of the jet producing members of the nozzle. y.
In Fig. 5 the body 5 is modified and has threads E for the nut 1, and threads I8 for the sleeve valve I5c both of the same and identical body diameter and pitch so that the valve can be screwed onto the body from the rear end after which the nut l is screwed into place. The zones of threads 6 and I8 are well spaced by a reduced peripheral groove G. The valve I5@ moves to and fro without ever uncovering its threads I 8 so that they do not corrode and stick the valve.
Numerous features of the instant nozzle or shower head are disclosed in the abandoned application Ser. No. 661,961, filed April 13, 1946.
A very distinctive feature of this invention is that, additively, the ring of spaces at the roots of the splineways I3 and the ring of spaces at the roots IES, Fig. 3, separating the splines l5 in their system, form a complete circle of ducts longitudinally of the tip and the sleeve from which will issue a full circular spray as the splines back away from the central, fixed tip, as will be appreciated by observing Fig. 1. This is so even if roots of the splineways I3 are in an inner circle as to the roots |53. The sides of the splines ride close to the radially divergent sidewalls of the splineways, Figs. 3 and 4 and as the splines are shifted inwardly from the conical tip 9 channels will be opened along rthe surfaces I3 and I 5s, Fig. 3, which are parallel to the pitch of the conical tip. Therefore sprays will issue from these narrow channels which are gradually. increased as the sleeve I5 is screwed into the threaded shell I 8. The word root used herein means the bottom of the spaces between the teeth-like portions of the tip 9 and the sleeve I5, and the arrows thereat indicate stream flow along these root channels.
What is claimed is:
l. A spray nozzle comprising a stationary, hollow body having on its outer end an inwardly directed, fixed conical tip having an annular system of ow splineways in its eonic face all convergeht toward the axis of the body, a hollow sleeve which is open at each end and is keyed to the said body for longitudinal shift therealong and forming a fluid chamber inward from the tip and having xed in its outer end an internal sys- 5 tem of splines complementary to said splineways and longitudinally movable into and from the splineways to close, or to vary the flow capacity or to fully open the splineways; said body having an external stop shoulder on its rear end, a nut, on the body, opposite to said stop shoulder, and said means including a shell enclosing said body and a part of the sleeve and being rotatively retained between said nut and said shoulder.
2. The nozzle of claim 1; the roots or bottoms of the said splineway system being parallel constantly to the opposite ridge faces of their respective sleeve splines.
