A water spray device for cleaning the hull of a boat is disclosed. The spray device includes a handle and wand portion. The handle portion has an angled portion separating an upper and lower part, a channel formed through the handle and a top and bottom open end. The top end engages a hose connected to a water source. A shut-off valve is disposed within the handle channel proximal to the top end. The wand portion is an elongated tube having an channel formed therein, an open top end for engaging the handle bottom end, a closed bottom end and a plurality of spray nozzles disposed along the wand. Water enters the handle portion, flows into the wand portion and out the spray nozzles. A user of the novel water spray device simply positions the spray nozzles towards the boat hull from the deck of the boat while holding the spray device and walks around the perimeter of the boat to quickly, easily and thoroughly clean the boat hull.

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.

A chalk line device adapted to receive chalk from a chalk refill container, the chalk line device includes a body defining at least one opening and a chalk line disposed within the body. A mounting structure provided adjacent the opening is configured to engage the chalk refill container in a sealed manner, whereby chalk in the chalk refill container may be emptied into the chalk line device generally without spillage through engagement of the mounting structure to the chalk refill container. The refill container has a flange extending along its opening, and is sealed with a removable cover. A door is slidably mounted within the mounting structure such that opening and closing of the door is coordinated with coupling/decoupling of the refill container.

Unitized sprinkler assembly including a housing assembly having an inlet end constructed and arranged to be connected with a source of water under pressure and a spaced outlet end, a manually adjustable control mechanism carried by the housing assembly, a sprinkler head assembly having an inlet end disposed to receive water under pressure flowing from the outlet end of the housing assembly, a base assembly constructed and arranged to support the assemblies on a ground area to be sprinkled, a structural connection between the sprinkler head assembly and the housing assembly constructed and arranged to enable the sprinkler head assembly to oscillate about an oscillatory axis with respect to the housing assembly, an oscillating mechanism mounted in the housing assembly constructed and arranged to be operated by the flow of water under pressure and connected with the sprinkler head assembly to oscillate the sprinkler head assembly about the oscillatory axis through repeated oscillating head cycles, an adjusting mechanism constructed and arranged to enable the distance of the head stroke of each oscillating head cycle to be adjusted within a range between a minimum head stroke distance and a maximum head stroke distance, and a control member to control selectively the width of the spray patter discharged from the sprinkler head assembly. The housing assembly may include first and second housing assemblies.

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. A second housing assembly having an oscillating mechanism also is provided, and a sprinkler head assembly is connected to the oscillating mechanism. The first housing assembly, the second housing assembly, and the sprinkler head assembly are supported by a base assembly on the area to be sprinkled. Additional features, such as adjusting rings and spray width control members, also may be provided.
