Abstract: An improvement to sprinkler heads used in tree orchards and the like wherein it is undesirable to have irrigation water maintaining the trunks of the trees in a constantly wet state. The sprinkler heads involved are the vertically disposed cylindrical type wherein a rotating nozzle at the top thereof creates a horizontal spray pattern. The improvement comprises a cylindrical collar for mounting on the sprinkle head body with at least one vertically dispoed wedge-shaped fin mounted thereon. By placing the fin radially between the nozzle opening of the sprinkler head and the tree trunk the wedge-shaped fin splits the stream which would otherwise strike the tree trunk and causes it to pass on either side of the tree trunk. Various embodiments are shown to provide adjustability of the fins position and a plurality of fins on one sprinkler head.

The operation of the flow control member is such that flow control adjustment can be obtained by a turning movement from a center position in either direction.
Abstract: A sprinkler and valve operator is disclosed that enables a single rotatable sprinkler head to be mounted coaxially to an upright irrigation pipe valve. The operator is comprised of two independently coaxially rotatable pipe sections that include a central valve operating mechanism. The lower pipe section includes mechanisms for releasably attaching the operator to a standard upright irrigation pipe valve. The valve operating mechanism engages and rotates the irrigation pipe valve actuator in response to rotational movement of the upper pipe section. A removable tripod may be provided to brace the pipe sections against operating forces produced through rotatable sprinkling head attached to the upper pipe section.
Abstract: Trees, such as fruit bearing trees in drought-stricken areas, are individually watered to conserve the water supply while saving the valuable trees. A radially slotted tub-like irrigator engages around the tree trunk and delivers water in a controlled manner to both the tap roots and the peripheral root network of the tree. No water is wasted and the time span for irrigation can be adjusted. The device is characterized by simplicity and economy of manufacturing and ease of installation.
Abstract: A resilient sprinkler riser is described for mounting a pulsating type sprinkler head wherein a nozzle is utilized to direct a spray jet of water in a radial direction from a vertical axis of rotation while a pivoted deflector member operates to rotate the nozzle about the vertical axis. The riser includes a flexible tube that is coaxially mounted within an elongated closed helical tension spring. The spring is fastened at its lower end relative to the tube while its upper end is free to slide coaxially over the tube length. The spring is pretensioned to hold the pipe in an upright condition under the reaction forces exerted by a jet of water exiting through the sprinkler nozzle. However, the spring tension is not sufficient to hold the tube in an upright condition when excessive external lateral forces are applied. When this happens, the riser will deflect in the direction of the force. When the force is removed, the riser will spring back to a normal upright condition.
Abstract: Cooling water at 39.degree. F is made available at low cost all year round by erecting towers in farmer's fields and spraying the water in the air around the towers to cool the water during the winter. The cooled water is collected and stored in a lake. During the summer the same towers and water spraying system is used to act as a permanent irrigation system with the water from the lake sprayed when needed on the farmer's crops. Since the users of the cold water from the lake for cooling water have to and can easily afford to pay for the whole system, which includes a very good drainage system, farmers will greatly profit and therefore greatly favor the installation of such a system on their farms.
Abstract: An elongated shower pipe, extending across a paper stock treatment machine, such as a Fourdrinier, instead of being a uniformly simply supported span, is supported on brackets at each end designed to significantly reduce the deflection of the shower pipe. The brackets include fixed supports inboard of the ends and deflection means, outboard of the supports, which apply a moment of force in a direction opposite to the forces exerted by the gravity on the central span of the pipe. Threaded means adjusts the amount of anti-sag force.
