Definitions

  • ABSTRACT A deflector spoon fitted on an end of an oscillating arm carried by a rotary sprinkler, the arm causing the spoon to move repeatedly into the water stream so as to impart a turning movement to the sprinkler; the spoon being so arranged that nozzles of a wide range of sizes may be interchanged without materially affecting the operation of the deflector spoon.
  • the present invention is directed to a rotary sprinkler having a deflector spoon in which the deflector spoon has a restricted water deflecting surface dimensioned for engagement by a decreasing proportion of the water as the volume of the discharge from the nozzle increases, so that the resultant force causing rotation of the sprinkler tends to remain constant or to undergo inconsequential change in the oscillation of the spoon supporting arm.
  • excessive swinging or oscillation of the arm is avoided thus permitting the use of a wide range of nozzle sizes while the remaining parts of the sprinkler remain unchanged.
  • FIG. 1 is a side view of a rotary sprinkler incorporating the deflector spoon.
  • FIG. 2 is a side view of the deflector spoon taken flow pattern.
  • FIG. 3 is a bottom sectional view taken through 33 of FIG. 2 and showing the water flow pattern.
  • FIG. 4 is a side view corresponding to FIG. 2 showing a nozzle tip with a bore of large size and also showing the water flow pattern.
  • FIG. 5 is a bottom sectional view taken through 55 of FIG. 4 and showing the water flow pattern.
  • the journal pin receives an oscillating lever 7 having a counterbalancing arm 8 and a deflector spoon arm 9 in diametrically disposed relation.
  • the oscillating lever 7 is urged in one direction by a spring 10 and is urged in the opposite direction by the interaction of the water striking a deflector spoon carried by the oscillating lever.
  • a special deflector spoon l 1 is formed integral with the oscillating lever 7 or is attached thereto.
  • the deflector spoon includes an offset bracket portion 12- joined to the deflector spoon arm 9. Extending in a direction essentially radial with respect to the axis of the sprinkler body are radially outwardly diverging upper and lower side walls 13. Connecting the radially inner portions of the side walls 13 is an initial deflector web 14. Extending between the side walls 13 and arcuatively as well as radially offset from the web 14 is an opposed deflector web 15.
  • the deflector spoon thus far described is similar to the conventional deflector spoon.
  • the opposed deflector web 15 of the conventionalspoon terminates in a curved deflector ridge which completely fills this space between the side walls 13 sothat all of the water issuing from the nozzle is deflected thereby when the spoon is in the water discharge path from the nozzle.
  • the central portion of the deflector web 15 is provided with a'relatively narrow main deflector element 16 having a curved deflector face 17.
  • the deflector element 16 is bordered by side slots 18 bounded on their remote side by the radially outer portions of the walls 13. The surfaces of the two side slots are flush with the normal surface of the deflector web 15.
  • the deflector spoon is urged into the water stream issuing from the nozzle tip by the spring 10.
  • the spoon moves and is moved by the water in a counterclockwise direction as viewed from the top of the sprinkler but in a clockwise direction as viewed from the underside of the sprinkler, that is as viewed in FIGS. 3 and 5.
  • the water stream'of jet first engages the initial deflector web 14 which draws the deflector spoon into the water stream, that is,
  • the water is almost instantaneously deflected to the opposed deflector web 15. In doing so, a portion of the wateris further deflected by the main deflector element 16. This deflection is in a direction to cause a reaction on the spoon which drives'the spoon out of the water stream causing the oscillating arm 7 to swing in opposition to the spring. Energy is stored in the spring which drives the oscillating lever to return the deflector spoon into the water stream. Sufficient energy is stored in the oscillating lever as to cause it to strike the frame 6 turning the sprinkler body a slight amount before the water reaction on the main deflector element 16 again drives the deflector spoon and oscillating lever out of the water stream.
  • FIGS. 2 and 3 show the spray pattern from a nozzle tip of smaller bore and FIGS. 4 and 5 show the spray pattern when the nozzle bore is increased in diameter.
  • a deflector spoon for rotary sprinklers having a nozzle branch adapted to receive selectively a set of nozzle tips having a preselected range of bore diameters, and an oscillating arm, said deflector spoon comprising:
  • the main deflector element having directing means for directing water from said nozzle along a path of predetermined width, and a deflector surface portion in said path, of fixed width less than that of said path and an effective water deflecting area less than the area of the stream issuing from.
  • an initial deflector web carried by the supporting means is interposed between the nozzle tip and the main deflector element for flattening the stream of water and directing the water stream into said path.
