Abstract:
A wave sprinkler assembly in which the tubular spray assembly comprises a tubular member and one or more elongated strips of flexible material having a series of longitudinally spaced water stream outlets extending therethrough, the strips are assembled with the tubular member by inserting them therein through an end and moving them radially outwardly into an operative position wherein the water under pressure within the interior of the tubular spray assembly acts on the strips to enhance their engagement with the tubular member. The strip provides an annular seal of flexible sealing material extending around the exterior of each of the controllable water stream outlets, and a control member is mounted on the elongated tubular assembly for movement between a full width operating position and a width limiting position. The control member includes a control section associated with each annular seal and the controllable water stream outlet around which it extends. Each control section has a surface area movable into engagement with the associated annular seal to prevent a water stream from issuing from the controllable water stream outlet around which it extends and an open area movable over the controllable water stream outlet around which the associated annular seal extends to allow a water stream to issue therefrom.
Abstract:
A valve suitable for lawn and garden irrigation with a fluid inlet and two fluid outlets and a means for switching the flow of water from one outlet to the other based upon a predetermined flow of water. A plurality of valves may connected in series to irrigate several garden areas by connecting the inlet of each valve with the second outlet of the previous valve, except the inlet of the first valve which communicates with a water source.
Abstract:
An adjustable oscillating wave-type irrigation sprinkler having an impact or impulse drive type mechanism for effecting side-to-side oscillation by a spray tube about a horizontal axis, the drive mechanism including a pair of drive spoons coupled to impact arms journaled for rotation relative to the spray tube and intercepting streams of water from the spray tube to produce incremental rotation of the spray tube about the horizontal axis.
Abstract:
An improved oscillating sprinkler comprising a frame having a sprinkler tube mounted for oscillating movement on the frame. An inlet water housing is mounted on the frame and supplies water to the sprinkler tube. The sprinkler tube is driven in an oscillating path by a crank arm, and an eccentric gear mechanism driven by the water being supplied to the sprinkler tube is operably connected to the crank arm. The eccentric gear mechanism is constructed to provide a variable speed output that balances the varible speed output of the crank arm to provide a substantially uniform velocity of oscillating movement for the sprinkler tube. The sprinkler also includes a mechanism for varying the effective length of the crank arm to change the arc of oscillation of the sprinkler tube, and a slip clutch mechanism interconnects the inner end of the sprinkler tube to the housing to permit the sprinkler tube to be manually rotated to shift the spray pattern to one side or the other.
Abstract:
An oscillating sprinkler is specially designed to facilitate assembly, as well as disassembly for purposes of repair of replacement of parts, without sacrifice of water-tight integrity and with improved operating characteristics. The housing for the impulse wheel and for supporting one end of the sprinkler tube is formed of two parts snapped together to effect the necessary seal, the sprinkler tube is mounted therein by a snap action insertion, thereby to define an operating subassembly, and that subassembly is reliably assembled with a mounting subassembly by sliding insertion and snap action retention. The sprinkler tube is sealingly journaled in such a manner as to produce very low friction, thus reducing the load on the impeller wheel and enabling the sprinkler to have a very low pressure drop therethrough, thereby increasing the sprinkling range of the device. The linkage between the impeller wheel and the sprinkler tube is manually accessible and is provided with a snap connection so that the linkage can readily be manually disconnected and connected. The construction lends itself to producing a low-profile, low cost unit.
Abstract:
A lawn sprinkler is disclosed of the kind in which a tubular perforated rocking member dispenses irrigation water, the improvement consisting in that the mechanisms which impart to the tubular perforated member the rocking motion are enclosed in a sealed box the lid of which is conveniently removable, the gears and other component parts of the rocking mechanism being so arranged as to be capable of being individually removed and reassembled, each component part being univocally positioned. Thus maintenance, cleaning and replacement of the component parts of the rocking mechanism becomes both an easy and convenient operation.
Abstract:
A snap-action toggle valve reverses the direction of an oscillating sprinkler powered by a paddle-piston motor. Adjustable stops on the sprinkler tube trip the valve at the end of each sweep, alternately opening left and right motor chamber channels interconnected to a sprinkler supply channel feeding the sprinkler tube without interruption. A special vane on the sprinkler tube where it intercepts the sprinkler supply channel prevents vortex action. The edges of the paddle-piston are sealed to the motor chamber by a flanged slip-on wiper.
Abstract:
For overcoming the dead centers of the motion of an oscillable sprinkler of the kind used for watering "greens", gardens and the like, in which the swing of the sprinkling arm is determined by the water itself, an oval cam mechanism is provided which can also limitedly adjusted as to its angular phase. A more uniform watering density can be obtained the whole watered plot throughout.
