Abstract: System and process for producing different embodiments of sprinkler assemblies uses two different first housing assemblies, from which one first housing assembly is selected for producing a desired sprinkler assembly embodiment. Each first housing assembly is replaceable with the other and includes an inlet end and a spaced outlet end; the inlet end of each first housing assembly is configured for connection with a source of water under pressure. Each first housing assembly also includes an adjustable flow control mechanism to control the flow of water under pressure through the first housing assembly. The control mechanism may include a manually-actuated moveable valve structure to control water flow rate, or a timing mechanism to select a duration for the water flow. By providing a first housing assembly with a control mechanism that is different from that of the other first housing assembly, the sprinkler assembly embodiment produced will depend upon the first housing assembly that is selected.

Abstract: A truss assembly (10) for supporting lights (30) is described. The assembly includes a truss frame (12) with individual units (16) within which is mounted electric lights. The truss frame has end plates (34) at each end (12B) and rotatable plates (52) mounted onto each end plate by bushings (58) which are fixably mounted within the rotatable plates. Locking assemblies (64) extend through the rotating plates and into indexing holes (50) in the end plates. Support receivers (70) are attached to the rotatable plates and mount on top of support stands (74) in order to keep the truss assembly in an elevated position. In a second embodiment, the truss frames are joined together to form a longer truss assembly. Several truss assemblies are connected together by forked support stands 78 at the corners to create a truss system 80 which encloses an arena 86. The fixed bushings within the rotatable plates enable the truss frame with the electric lights to be rotated into various positions.

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.

Abstract: A pop-up sprinkler assembly for installation within the ground and for manual connection from a position above ground with an above ground hose as a source of water pressure. The pop-up sprinkler assembly includes a housing structure having an annular opening and exterior suitable for installation within the ground in a fixed operative position. The housing structure has a inlet passageway communicating with the annular opening. A hose connector is in the passageway for connection to an above ground hose. A sprinkler head is mounted in the annular space that is generally at ground level when the sprinkler head is in a lower storage position. An annular seal is provided between the sprinkler head and the housing structure so that the communication of water pressure with the annular space results in water pressure-biased movement of the sprinkler head from the lower storage position to a raised operative position.

Abstract: A hose nozzle comprising a tubular body having female threads on one end portion thereof. The tubular body provides a hand grip portion adjacent the one end portion suitable to be grasped in one hand with the thumb naturally extended into an actuating position on an opposite end of the hand grip portion. The tubular body defines an interior water passage and has an inner annular ball valve seat facing toward the passage therein on which a ball valve is mounted for varying the flow rate of the water through the valve seat. A manually actuatable flow directing assembly is provided for receiving water flowing through the valve seat and for directing the same into variable stream formations. An actuating member is provided having a thumb-engaging portion extending in the actuating position for effecting pivotal movements of the actuating member about the pivotal axis of the ball valve by thumb engagement.

Abstract: A uniform water pattern oscillating wave type lawn sprinkler in which the impeller has a dynamic impeller ratio as herein defined of less than approximately 0.30, the reduction gear assembly has a gear reduction ratio of greater than approximately 400 to 1 and an efficiency of at least 26% preferably 39% or greater and the heart-shaped cam motion-transmitting mechanism has a heart-shaped cam with a cam factor as herein defined of less than approximately 3 so as to enable said housing structure to be an optimal minimum in size.

Abstract: A three component coupling assembly consisting essentially of plastic male and female coupling members and an annular seal. The female member has a male fitting engaging end portion formed with interior threads for cooperatively threadedly engaging a threaded male hose fitting. The remaining female coupling portion has a generally cylindrical interior periphery of a smaller diameter size defining at a position adjacent the inner end of the interior threads an annular shoulder. The interior periphery has formed therein a plurality of annularly spaced grooves extending from the outer end thereof through the annular shoulder and a corresponding plurality of correspondingly annularly spaced notches extending from the annular shoulder toward the outer end. The seal has an outer annular portion seaingly engaging an uninterrupted outer sealing surface of the shoulder and an inner annular portion extending over the notches and grooves formed in the shoulder.
