Abstract: An automatic cleaning device for use on a stock farm, including an automatic switching system, a transmission case, a sprinkling system and a water pump. The automatic switching system utilizes water pressure to push a valve seat so as to achieve an automatically switching effect without using electric power. By means of a splined circular rod, a first and a second rotary rods and a one-way bearing in the transmission case in cooperation with a linking lever and connecting arch block of the sprinkling system, a linear movement of a slidable piston is converted into a speeded up and down pivoting and left and right swinging movement of a sprinkling head of the sprinkling system. A flow controlling mechanism of a hydraulic means is used to achieve alternate fast and slow cleaning operation of the sprinkling system. By means of changing pivot holes of a connecting block for pivotally connecting with the linking lever, a starting point of the sprinkling head is adjustable.

Abstract: A tube jetting apparatus for cleaning the interior surfaces of tubes such as those in heat exchangers. The jetting apparatus includes a hydraulically actuated lance and piston assembly in a housing. High pressure fluid is directed through ports in the lance and also directed across the piston to actuate the lance and piston assembly while providing high pressure fluid to a jetting nozzle on the lance. The speed of the lance and piston assmbly is controlled and jetting action occurs on both the outward and return strokes. On the return stroke, a pressure relief system is provided to relieve the system pressure through a differential pressure relief valve. A stroke limiter is provided which utilizes a collet for grippingly engaging the lance at a predetermined location thereon while minimizing damage to the surface of the lance.

Abstract: A generator for cyclically moving jets comprises a housing including a chamber having a circular track therein, a body disposed in the chamber and rollable along the circular track, a hollow revolvable axle coupled to the body and extending to outside of the chamber and rotatably born in and sealed to the housing, a nozzle attached to the axle outside of the chamber for issuing at least one jet misalignedly in relation to the axis of rotation of the axle, and a fluid flow supply leading to an upstream region of the chamber. In operation, fluid flows past the body, through the hollow revolvable axle and issues from the nozzle as a jet. The body rolls along the circular track as a consequence of fluid-dynamic forces acting on the body. A fountain employs the generator for dynamic display of the cyclically moving jets issuing therefrom.

Abstract: A hydroactuatable high speed spinner for car wash equipment and the like which is characterized by rugged, reliable design. The spinner is driven soley by water pressure, which may be on the order of 1,000 psi, wherein a unique turbine sleeve ensures high speed operation while still providing adequate pressure for scouring and washing by a relatively lightweight spray rotor carried on the sleeve in a sealed spinner assembly. As a consequence, effective cleaning is achieved with minimum water wastage and maximum conservation.

Abstract: An oscillatable nozzle sprinkler has a primary valve for controlling flow through a nozzle in a nozzle housing. An arc set control sets a desired angle of oscillation of the nozzle housing. An integrated system is set forth so that when a desired angle of oscillation is selected, the primary valve is positioned to provide a desired precipitation rate. A secondary valve is provided to achieve a uniform precipitation coverage.

Abstract: Lawn sprinkler incorporating a novel water distributing head having a "wobbling" motion. The base of the head is mounted loosely between shoulders near the end of a tubular water-supplying support arm. A water jet emerging from a nozzle at the end of the arm strikes internal vanes at the discharge end of the distributor head to cause the wobbling action. The support arm is journaled within a vertical bearing, and the action of the water jet causes the arm to be driven slowly through a circular path.

Abstract: An agricultural irrigation system having a fluid dispersion nozzle for controlling the flow rate and generating a resultant fluid stream characterized by uniform dispersal along the stream path. The nozzle has a housing member (10) which defines an inlet passageway (16), a nozzle outlet orifice (32), and an intermediate fluid chamber (30). A resilient flow control member (34) is located within the fluid chamber (30) and has an orifice (36) centrally located therein and axially aligned with the inlet passage (16) and the nozzle orifice (32). The nozzle orifice has located along the inner periphery thereof a plurality of circumferentially equally spaced and radially inwardly projecting deflector members (38, 40, 42) which are effective for reducing a portion of the resultant fluid stream velocity therethrough. The fluid dispersion nozzle is mounted on a rotary sprinkler head (50) which receives a supply of pressurized irrigation fluid from an irrigation system primary conduit (56).

Abstract: A cleaning machine for cleaning dirty, greasy or otherwise polluted metal parts comprises a foraminated basket for receiving said metal parts, which basket is rigidly mounted for rotation with a rotatable wheel. The wheel is driven by spray jets from spray nozzles around the periphery of the wheel. The spokes of said wheel have their free ends provided with vanes mounted thereon in a freely swingable position. Within certain limits of the rotation speed of the rotor the vanes are hit by the spray jets. If a specific speed is exceeded, the vanes are swung outwards by centrifugal forces and brought beyond the effective operation area of the spray jets. In the absence of a driving force the rotation speed will go down. In this way an automatic controlling of the rotation speed is possible.
