Abstract: A two-piece adjustable dial assembly between a link and a water discharge tube of a sprinkler for causing the rotational movement of the water driven shaft of the sprinkler to be transmitted through the link to the water discharge tube in any selected one of a plurality of different oscillatory cycles of movement. The two-piece adjustable dial assembly includes an arm member molded of plastic material having a mounting portion fixedly secured to the water discharge tube and a cylindrical portion having an axis disposed parallel to the oscillatory axis of said water discharge tube, and a dial member molded of plastic material extending through the cylindrical portion of the arm member and rotatable with respect thereto about the axis thereof. The dial member has a knob portion manually engageable to effect rotation of the dial member, a pivotal connection with the other end of the link and an elongated resilient cantilevered latching portion formed integrally with the dial member.

Abstract: A step-by-step rotary sprinkler having a combined stream coherency diffuser and distance control baffle member formed of sheet metal to include an arm portion disposed generally vertically having an aperture extending horizontally through one end thereof, a baffle portion bent outwardly at generally right angles from the opposite end of the arm portion and a relatively small diffuser portion bent outwardly at right angles from the free edge of the baffle portion and a manual engaging tab also bent outwardly at right angles from the arm portion, and a pivot assembly extending through the aperture to mount the arm portion on the sprinkler body for pivotal movement into any desired position of adjustment within a predetermined range wherein the radially outermost point of the member is disposed radially inwardly of the radially outermost point of the drive spoon, the positions of adjustment within the range including (1) a diffused only position where the diffuser portion extends into the stream when the drive s

Abstract: A step-by-step rotary sprinkler head having an impact arm with a drive spoon thereon. The drive spoon is preferably of the anti-backsplash type and includes a pull-in reactant surface and a drive-out reactant surface spaced radially and laterally outwardly of the pull-in reactant surface. The pull-in reactant surface has a slot formed in the central portion thereof for enabling a portion of the stream issuing from the sprinkler head outlet to continue its movement into the slot and outwardly therefrom without being deflected onto the drive-out surface when the drive spoon is in stream engagement so that the reactant force established on the drive-out surface is reduced in relation to that which would be established by the deflection of the entire stream thereon.

Abstract: A sprinkler spray head consisting of three components preferably molded of plastic material, namely, a body member, a cap member and a flow control member. The mounting and sealing of the components is such that several different spray patterns can be obtained by utilizing several different cap member configurations with the same body and flow control members. 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 part-circle step-by-step rotary sprinkler head having an improved anti-backsplash drive spoon integrally formed as a part of the impact arm and having a construction related to the longitudinal axis of the outlet when the arm is in its impact limiting position which comprises upper and lower walls in a position to receive the stream therebetween, an initial stream engaging wall extending between the upper and lower walls and a final stream engaging wall extending between the upper and lower walls spaced with respect to the initial stream engaging wall in a position (1) with all portions thereof disposed outwardly of all portions of the initial wall in a transverse direction corresponding to the direction of movement of the spoon away from its impact position, (2) with a longitudinally inward portion thereof disposed in longitudinally lapped relation with a longitudinally outward portion of the initial wall and (3) with a longitudinally outward portion thereof disposed longitudinally outwardly of the longitu

Abstract: Apparatus for attachment to garden hoses in a wide range of sizes to provide a conventional hose fitting on an end thereof, which consists essentially of a tubular shank member molded of plastic material having exterior ring sections on one end thereof adapted to enter the interior of the hose end and a fitting on the opposite end thereof, a tubular collar member molded of plastic material having an internal threaded section on one end thereof engageable with an exterior threaded section on the shank member and an interior hose engaging flange on the opposite end thereof. A plurality of sizing members of different internal diameter sizes in the form of split rings is provided for engagement in abutting relation to the interior surface of the annular flange of the collar member.

Abstract: A sprinkler head comprising an annular sprinkler body of molded plastic having a tubular member of molded plastic snapped into operative fixed relation within the central portion thereof. A flow adjusting screw is threaded within the tubular member and has its head in adjustable flow restricting relation to inlet passages in the sprinkler body. Water flowing through the controlled inlet passages moves upwardly along the interior of an annular wall in the annular body, outwardly along an end wall of a molded plastic spray adjusting member threadedly mounted on the upper end of the tubular member, downwardly between the exterior of the annular wall and the interior of a peripheral wall of the adjusting member and then radially outwardly between cooperating flow pattern defining surfaces on the spray adjusting member and sprinkler body.

Abstract: A traveling sprinkler and guide wheel assembly therefor which minimizes the chances of the sprinkler leaving operative engagement with a hose defining a path of travel for the sprinkler. The sprinkler includes an elongated body with a water distributing assembly, a pair of cleated drive wheels mounted near the rear thereof, and a guide wheel assembly including a split guide wheel mounted for rotation with respect to a horizontal shaft adjacent the front thereof. Each half of the guide wheel includes a number of radially extending portions defined by slots disposed around the circumference thereof having tip portions extending axially outwardly therefrom.

Abstract: A tool for gaining access to a pop-up sprinkler head when in a sprinkler casing, and for insertion into and removal from the casing of the sprinkler head; also a method for using the tool for gaining access to the interior of the casing and for sprinkler head removal. A tool consisting of a gripping portion for a gripping a part of the sprinkler head attaching the head to the casing, a handle, a lever interconnecting the handle and gripping portion, and portions for holding a pop-up cover out of engagement with the top of the casing, may be inserted into the casing to effect removal of the head from the casing while not requiring that the cover be manually head out of engagement with the casing top. The tool may also be used merely to allow an individual to gain access to portions of the head within the casing with both hands, one hand not being required to hold the cover out of engagement with the casing top.
