This invention relates to a sprinkler device and pertains particularly to an improved type of sprinkler nozzle.
One of the primary objects of the present insprinkler head or nozzle and an adjustable valve vertically mounted therein whereby the water passing therethrough may be regulated into the desired height of spray.
Another feature which goes hand in hand with the one just set forth is that the quantity of water which passes through the nozzle may be regulated. As a matter of fact, I provide common means whereby regulation vof the spray issuing from the nozzle and the amount of water passing through the nozzle may be regulated and controlled.
Yet another object of my invention is to provide a sprinkler head or nozzle in which the valveor water diffusing unit may be readily removed for cleaning or to be substituted by another type of unit.
Briefly described my invention consists of a head having an outlet pipe leading into the bottom side thereof and a sleeve threaded down into its upper portion. A valve is slidably mounted in the sleeve and a collar is threadedly engaged with the bottom of the valve element. This collar has a hole or holes therethrough which may aline with passages leading into the valve element and rotation of the collar on its threads tends to open or close the passageway in the valve element, thus regulating the amount of water passing upwardly through the valve. Also,
this collar may be adjusted along the length of the valve element thus controlling or regulating the amount of movement of said valve upwardly whereby the openings between the upper part of the sleevev and the lower part of the valve head may be increased or diminished thus regulating the spray flowing therefrom.
The invention will be best understood from a consideration of the following detailed-description taken in connection with the accompanying drawing forming part of the specification, with the understanding, however, that the invention is not confined to any strict conformity with the 1931. Serial No. 555,182 I (01. 299-01) valve and the collar-removed from the head.
Fig. 5 is a cross sectional view taken through a modified form of my device.
Fig. 6 is a view taken along the line 6-6 of Fig. 5.
Fig. 7 is a view in cross section illustrating another modification of my sprinkler head.
Fig. 8 is a fragmentary view taken at right angles to Fig. 7.
Fig. 9 is a view i '7. w
Similar numerals refer to similar parts throughout the several views.
.In Fig. 1, numeral 10 designates a lawn surrounded by a sidewalk 11 and being sprinkled by means of a series of sprinkler heads or nozzles. For convenience in illustration the sprinkler heads are under only about one-half of their normal pressure and hence certain portions of the lawn are not being sprayed. Whenever the nozzles are under normal pressure the sprays issuing from the several nozzles overlap so that the entire lawn is properly and completely sprayed. The corner nozzle sprays through about one quarter of a circle while the two nozzles back taken along the line 9-9 of of this corner nozzle spray through about half circles. The remaining nozzles, such as illus trated in Figs. 2, 3 and 4, spray through. either a complete circle or any part thereof as desired.
Referring particularly to Figs. 2, 3 and 4, 9 designates a head having a recessed upper portion 8, 'a lower depending portion 12 and being flattened as at 13 whereby a wrench or the like may be utilized therewith. An outlet pipe 14 is threadedly engaged into the depending portion 12 as at 15 and water is adapted to be supplied to the outlet pipe in any desired manner. A threaded opening 16 connects the recessed portion 8 with the interior of the outlet pipe 14.
A sleeve 20 is adapted to be threaded downwardly into thev threaded opening 16'as shown in Fig. 3. The upper end of the sleeve member is recessed to form a tapered portion 21.
A valve element 30 is cup-shaped in form and has a stem 31 with a head 32 at the top thereof rigidly attached to the cup-shaped member by a press fit therein. The valve head 32 is beveled at its lower edge as indicated at 33 thereby forming a surface against which the water flowing out of the nozzle impinges. Thus the surface 33 coacts with the surface 21 to regulate the amount of water which is forced'outwardly through the valve element. The cup-shaped member has openings 34 near the bottom thereof as clearly shown in Fig. 3.
When the water pressure is turned off the sur face 33 seats upon the surface 21 thereby preventing surface water or dirt from entering the system.
A collar is threadedly engaged onto the lower portion of the valve element 30, this collar 40 having oval openings 41 therein. See Figs. 3 and 4.
The operation of the valve just described is easily understood. The collar member 40 may be advanced or retracted along the valve member 30 by rotating it thereupon, and as the valve element 30 is slidably mounted in the sleeve member 20 the adjustment of the collar 40 thereon regulates this reciprocating vertical movement. As shown in Fig. 3, the water is flowing upward- 1y through the sprinkler head and the pressure of the water forces the valve element 30 upwardly until the top of the collar 40 abuts against the lower edge of the sleeve 20. When the water is turned off the valve element drops downwardly and the head 32 of the valve element rests against the top edge of the sleeve 20. In other words, the surface 33 snugly engages the surface 21 thus completely closing the valve. If a finer spray is desired, the sleeve member 20 is bodily rotated and the entire assembly is removed from the head 9, the several parts which are removed being shown in Fig. 4. The collar 40 might now be rotated so that the distance of the head from the sleeve may be adiusted thus giving the desired spray. Also, by rotating the openings 41 in the collar 40 relative to the holes 34 in the cup-shaped member 30 the amount of water which passes through the valve may also be regulated.
Referring now to Figs. 5 and 6, which show a modification, such as is indicate, at the righthand side of Fig. 1, designates t e sleeve which has a slot 51 cut therein. A key 52 rides in this slot and also in a slot 53 formed in the valve ele ment 54. Thus the valve element 54 is main-.
tained from rotation with respect to the sleeve 50 and hence the water, which'issues in the form of a half or three-quarters spray, may be thrown in the proper direction.
The valve member 54 has an opening 55 leading centrally therethrough and this opening extends laterally as clearly shown in the dotted lines in Fig. 5, A collar isthreaded onto the bottom of the valve 54 and an oval opening 61 therein is cooperatively associated with the opening 55 whereby the quantity of water flowing through this nozzle may be adjusted. The spray is regulated by threading the collar 60 along the valve element 54 as previously set forth in connection with the preferred modification.
Referring to Figs. '7, 8 and 9, numeral indicates a sleeve which has openings 71 therethrough as shown in Fig. 7. These openings admit the water into the interior of the sleeve. The sleeve is threaded exteriorly in order to receive a collar 60 such as shown in,Fig. 5. A valve element '72 is enlarged as indicated as 73 whereby it may be press fitted into the sleeve member '70 whereby the same are made as one.
The upper end of the valve element 72 is conical in shape as indicated at 78, the lower face of this conical portion deflecting the water outwardly when the device is in operative position and seating upon the beveled portion of the member 50 when the device is closed and inoperative.
As clearly shown in Figs. 7 and 8, the member '70 is cut away as indicated at '74 in order that the water may be thrown in the desired arc. It is obvious that this cut away portion may be varied as desired.
As shown in Fig. 9, the sleeve '10 has a rib '75 extending therefrom, thisrib having the same purpose as the key 52, see Fig. 6, that is, preventing the sleeve 70- from rotating and thus keeping the nozzle spraying in the proper direction.
Having thus revealed this invention, 1 claim as new and desire to secure the following combinations and elements, or equivalents thereof, by Letters Patent of the United States.
