Application July 21, 1937, Serial No. 154,762
7 Claims.
The main objects of this invention are:
First, to provide a sprinkler head of the lawn sprinkler type which discharges a very uniform spray covering a relatively large area.
Second, to provide a lawn sprinkler of the popup type in which the parts are simple in structure and easily assembled and disassembled, and one which is not likely to become clogged, but
, should it become clogged is very quickly cleaned or freed from the obstruction.
Third, to provide a spray head or nozzle which may be readily adjusted or adapted for the discharge of a predetermined volume of water or for particular pressures.
Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined and pointed out in the claims.
A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing, in which:
Fig. 1 is a fragmentary view mainly in central longitudinal section.
Fig. 2 is an enlarged fragmentary partially sectioned view of the nozzle member.
Fig. 3 isa transverse section on line 3-3 of Figs. 1 and 4.
Fig. 4 is a side elevation with the nozzle in its projected or spraying position.
Fig. 5 is an enlarged detail section of a slightly modified form or embodiment of my invention.
Fig. 6 is a fragmentary view mainly in vertical section of a slightly modified form or embodiment of my invention.
Referring to the drawing, the tubular body member I of my spray head is internally threaded at 2 so that it may be screwed or threaded upon a riser of a Water distributing system. The body member I is provided with an internal annular flange 3 intermediate its ends conformed to provide an upwardly facing shoulder 4 and a downwardly facing conical seat 5. The body member in the embodiment illustrated is provided with an annular recess 6 in its upper end and with a longitudinal groove 1 above the flange 3. The
relation of these features to the coacting parts will appear as the description proceeds.
The tubular nozzle member 8 is provided with a tubular stem 9 connected to the nozzle through a coupling member Ill which is threaded into the coupling. This coupling member is provided with a lug I l at one side slidably engaging the groove 1. The stem is provided with a flange l2 at its lower end having a curved face E3 on its upper side which coacts with the conicalseat 5 to form a valve when the nozzle is in projected position; further, this curved face I 3 coacting with the conical seat 5 acts to center the nozzle when it is projected by the force of the Water. The projected or operative position is shown in Fig. 4.
The nozzle member is provided with an internal flange M which serves as a support forthe tip retaining member l5. The nozzle is provided with a series of V-shaped notches H5 in its upper or outer end, these notches being radially disposed and in the preferred embodiment illustrated having inwardly inclined bottoms H. The notches form a series of jet orifices l8 and extend through the wall of the nozzle member so that they open into the inner surface l9 thereof, which in a nozzle designed to cover a complete circle is cylindrical.
The tip member 2|] is provided with a stem 2| having threaded engagement with the retaining member l5. This tip member has a portion 22 fitting within the notched or serrated portion of the nozzle member and partially closing the jet orifices.
In the embodiments shown in Figs. 1-5, inclusive, the tip member is provided with a flange 23 which seats or rests upon the end of the nozzle member. However, in the embodiment shown in Fig. 6 this flange is omitted and it is not essential to effective spraying although it adds somewhat to the appearance of the structure and it serves as a stop for the tip. The tip is provided with a head portion 24 adapted to seat in the recess 6 and constituting a closure for the spray head. It is intended that in manufacture the under side of the flange 23 shall be machined or cut away to the desired extent to control or determine the capacity of the spray head, that is, it is not usually deemed desirable to permit a Wide range of adjustment on the part of the user of the spray heads, although it is not necessary that the flange be completely seated in order to secure effective spraying.
When it is desired to clean the spray head or to free the jet orifices from obstructions, the tip may be completely removed and the obstructions brushed away, or the tip may be partially unscrewed and the obstructions removed by flushing.
In Fig. 5 the nozzle is beveled at 28 but this is largely a matter of manufacturing convenience and does not affect the result.
In the embodiment shown in Fig. 6 the tip is provided with a shoulder 25 which serves as a stop. In this embodiment the retaining member 26 is formed integrally with the nozzle member. 55
In this embodiment the shoulder 25 is suitably machined to secure the nozzle adjustment for the tip, that is, the adjustment designed by the manufacturer, but again the tip may be backed off partially to increase the capacity of the jet orifices if that is desired. The inner surface 2! of the tip is preferably conical in form while the opposed surface l4! of the nozzle member is also preferably conical. These surfaces 2! and MI are preferably substantially parallel as illustrated. This results in avoiding angles and pockets that might produce unnecessary turbulence and effectively directs the water to the jet orifices.
In the embodiment shown in Fig. 6, the surface 26| of the nozzle member is conical and the delivery passages of the nozzle member cut into it. The same general result is present of directing the water and. minimizing turbulence.
Spray nozzles embodying my invention are highly efiicient and are found to produce a very uniform spray. The structure readily lends itself to making full spray heads,or quarter, half or three-quarter spray heads, as desired, that is, spray heads designed to cover the 360 degrees of surrounding surface or only a fraction of that surface, this being determined by the portion of the nozzle embraced by the serrations or jet orifices. While the heads without adjustment are effective through a very wide range of Water pressures, they are easily adapted to particular water pressures as I have pointed out.
I have illustrated and described my invention in an embodiment which is very practical. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed this disclosure will enable those skilled in the art to.
embody or adapt my improvements as may be desired.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. In a sprinkler head, the combination of a tubular nozzle member having a plurality of V- shaped radially disposed notches in its outer end extending through the wall thereof, and a tip member adjustably associated with said nozzle member and having a body portion fitting within the said. nozzle member to partially close the inner ends of said notches.
