Description

Nov. 7, 1961 w. GERRANS 3,007,
WATER SPRINKLER Filed March 25, 1959 Q IO I2 3- l6 INVENTOR.
WILLIAM L. emu/vs PATENT AGENT UnitedStat The present invention relates to water sprinkler systems and more panticularly, to the individual sprinklers, a plurality of which are employed in such systems.
Sprinkling systems have come into extensive use, both on small lawns and on large farms and ranches. In the latter type of installation, since extensive areas have to be covered, a jet-forming sprinkler has come mto extensive use, the sprinkler body being arranged to revolve slowly so that the laterally projecting jet will project water over a relatively large diameter circular area. To maximize such diameter, an appropriate jet-forming nozzle is removably secured in the sprinkler outlet. From time to time, the nozzle opening becomes clogged with foreign material to stop the flow of water therefrom and must be removed for cleaning. However, if the nozzle is'removed without turning off the main valve of the sprinkler system, which at times may be located one quarter of a mile or more from the particular sprinkler which must be cleansed, the attendant will be thoroughly drenched, and furthermore will experience extreme difficulty in replacing the nozzle against the pressure of the flowing water, which pressure at times may be 80 or 90 pounds per square inch.
Accordingly, it is a general object of the presentinvention to provide an individual water sprinkler WlllCh 1ncorporates therewithin a valve that is normally open but can conveniently be closed by an attendant desiring to cleanse the sprinkler nozzle or service any other part thereof.
It is a particular feature of the lnvention to provide a sprinkler which incorporates a valve 1n such a manner that the same is normally urged to its opened positron but can be conveniently engaged by a simple detachable operating member to effect closing and locking of .the valve in its closed position.
It is another feature of the invention to provide a sprinkler having a valve therein wherein certain operating functions of the valve are carried out through the use of certain sprinkler parts which therefore serve a dual func, tion.
More particularly, it is a feature of the invention to provide for the incorporation of a valve structure 1n a revolving type sprinkler wherein a minimum modification of the sprinkler structure need be made to enable addition of the valve thereto, wherefore substantially no increase in the cost of the sprinkler with the valve incorporated is necessitated.
These and other objects and features of the invention will become more apparent from a perusal of the following description of the accompanying drawing wherein:
FIG. 1 is an elevational view of a sprinkler incorporating a valve in accordance with the present invention, parts thereof being broken away to show interior details, the valve being illustrated in its opened position,
FIG. 2 is a view similar to FIG. 1 but with the valve moved to its closed position by engagement with an operating handle, and
FIG. 3 is a fragmentary sectional view taken along line 3-3 of FIG. 2.
Basically, the sprinkler illustrated in the drawing is of the conventional revolvable type with a valve structure added thereto in accordance with the concepts of the present invention. More particularly, as shown in the drawing, the sprinkler includes a hollow main body member having inlet and outlet portions 12, 14 formed therein. The inlet portion 12 is internally threaded for A 3,007,646 I Patented Nov. 7, 1961 reception of the external threads on the upper end of a vertically disposed hollow spindle 16, which at its lower end is supported for rotation within a nut 18 that provides for connection to a water supply pipe in the normal fashion. When so supported, the outlet portion '14 of the body member 10 is directed laterally and upwardly at a slight angle from the vertical axis of the inlet 12. This outlet portion 14 is also internally threaded for reception therein of a nozzle 22 having an appropriate jet-forming orifice extending axially therethrough.
In accordance with the present invention, the upper end of the hollow spindle 16 is formed to provide a conical valve seat 24 that is adapted to receive the conical end of a valve member 26, preferably formed from rubber or other resilient material. Such valve member 26 is mounted at the lower end of a substantially vertical valve stem 28 that projects slidably through a bore in the upper wall of the body member 10 and a second aligned bore formed in a cunved upward extension 10a of the body member. This upper bore is flattened on one side and the upper portion of the valve stem 28 which projects therethrough is also flattened as indicated at 28a in a similar manner wherefore the valve stem is precluded from rotation but permitted the aforementioned sliding motion enabling the valve 26 on its lower end to move into sealing engagement with the described valve seat 24.
In addition to its valve-supporting function, the valve stem 28 supports for rotation thereon the hub 30 of an oscillating arm 32, one end of which is arranged in a known manner to intersect the path of water laterally projected from the described nozzle 22. Diametrically opposite the oscillating arm 32, a hammer 34 projects from the hub 30 and a coil spring 36 is connected between the inner end of such hammer and the valve stem 28 to normally urge the hammer by torsional force against the previously described upwardly curving extension 10a of the body member 10. When the hammer 34 is so disposed against the extension 10a, the oscillating arm 32 is in jet-intersecting position. The end of such arm 32 is shaped so that the water engaging the same will urge the arm 32, its mounting hub 30 and the hammer 34 in a rotative direction such that the hammer is moved away from the upwardly projecting extension 10a of the body member and is thereafter returned to the illustrated position by the action of the coil spring 36. As a consequence, an oscillating action occurs and each time the hammer 34 engages the upwardly curving extension 10a on the body member, a slight rotative movement of the entire sprinkler is eflected. Thus, as is well known, a slowly revolving sprinkling action is obtained.
The coil spring 36 connected between the hammer 34 and the valve stem 28 is also under a slight degree of compression so as to normally urge the valve stem into its upper position, as illustrated in FIG. 1, but downward force against the end of valve stem will urge the valve 26 against the spring action into engagement with the valve seat 24. In order to provide such force, a simple handle 40 having a cupshaped receptacle 42 is adapted for operative engagement with the upper end of the valve stem 28, as shown best in FIGS. 2 and 3. Laterally-projecting pins 44 adjacent the lower end of the receptacle 42 form opposed latch members that are adapted upon depression of the valve stem 28 and rotation of the handle 40 to enter keeper notches 46 formed at the upper extremity of the upwardly curving body member extension 10a at positions on opposite sides of the bore therethrough. The screwed insertion of the valve-seat forming spindle 16 into the main body member 10 is adjusted accurately so that the valve 26 will come into sealing engagement therewith when the handle 40 has been applied to the valve stem 28 and latched in its locking position, as illustrated in FIGS. 2 and 3.
Quite obviously, when the handle 40 is turned so that the latching pins 44 are removed from the keeper notches 46 and downward pressure is released, the valve member 26 will be automatically returned to its upper position, such movement resulting from the action from the compressed coil spring 36 and also from the force of water against the valve, it being noted that the exposed surface area of the valve member 26 is greater on its lower than on its upper side. When the valve member 26 is returned to its fully opened position, it is disposed out of the path of flowing water so as not to interfere with such flow, as can readily be visualized by reference to FIG. 1.
The dual functioning of various parts in the described structure should be re-emphasized. The spindle 16 not only serves as a rotatable support but provides the valve seat 24 at its upper end. The valve stem 28 not only provides for motion of the valve 26 but provides rotatable support for the oscillating arm 32 and furthermore the spring 36 acts both torsionally on the arm 32 and compressively on the valve stem 28. Thus each of these necessary parts for the sprinkler mechanism also serve as essential elements of the valve mechanism in the illustrated preferred embodiment of the invention.
Various modifications and/or alterations can be made in the described structure without departing from the spirit of the present invention, and the foregoing description of a preferred embodiment is to be considered as purely exemplary and not in a limiting sense. The actual scope of the invention is to be indicated by reference to the appended claims.
