摘要： A versatile, easy to use, adjustable tool, paint, accessory and supply caddy for use on an extension ladder. The caddy can be used on ladders having rungs that are either round in cross section or have steps that are flat and more rectangular in shape. Upper and lower mounting cradles attach to any consecutive rungs of the extension ladder at two separate attachments points. A quick release, spring loaded clamping mechanism allows the ladder caddy to be quickly and securely attached and then removed from the ladder, with the upper and lower mounting cradles adjustable to accommodate different ladder rung/step shapes as well as diameters and distances between rungs. Paddle shaped trays can be locked in place on the caddy in a variety of positions, and the trays can swing over or under each other or be swung in opposing directions away from the ladder user thereby creating a useable work space adaptable to almost any ladder position.

摘要： A pop-up sprinkler of the type that includes a riser that moves upwardly out of a sprinkler housing when water pressure is applied and that allows manual adjustment of the angular orientation of the riser with respect to the housing to adjust angular orientation of the spray from the sprinkler, and provides for such angular adjustment by having a toothed flange associated with the riser in the housing which engages tabs associated with the housing, provides for longer life of the toothed flange and/or the tabs by providing slots extending radially inwardly in the toothed flange to reduce its rigidity to the extent that the teeth and/or tabs do not wear as quickly.

摘要： A ladder caddy for holding tools, small parts, and the like for a workman on a ladder includes four curved cradles for holding the caddy to the ladder, two of the cradles holding consecutive and respective rungs of the ladder when the caddy is mounted in a first position, and two of the cradles holding consecutive and respective rungs of the ladder when the caddy is mounted in a second position inverted and upside down from the first position. The caddy includes a tool holding structure extending outwardly from the ladder at an angle of approximately 15 degrees offset from perpendicular so that when the caddy is mounted on a leaning ladder the structure extends approximately horizontally. The caddy includes a clamp for clamping to the ladder, integrally formed tool holders, and a variety of accessories that mate with the caddy body.
