Abstract: A nozzle assembly includes a support member, a first tube, a second tube, and a baffling member. The support member defines a receiving hole and an opening communicating with the receiving hole. The first tube extends through the opening and defines a first space communicating with the receiving hole. The second tube is retained within the receiving hole and defines a second space communicating with the receiving hole. The baffling member is securely connected to an end of the second tube that is retained within the receiving hole. The baffling member forms a plurality of gaps for directing the airflow from the first space.

Abstract: A trigger actuated aerosol spray cleaning device is disclosed that has a removable snap-on cleaning head. The cleaning head can be snapped onto a handle by simple linear movement, and then can be removed by sliding a button. In one form, there is a lower connector on a mop handle that has two pivot pins biased apart by a spring. The pins have cammed ends that can be driven in towards each other as the mop handle is pressed against a receiver portion of the cleaning head. The cleaning head can then be removed by sliding a button connected to one of the pins to dislodge that pin from its pivot mount.

Abstract: A trigger actuated aerosol spray cleaning device has a cleaning head that swivel or be locked in different preset discrete angular positions relative to the device. The cleaning head pivotally mounts onto a swivel part of a coupler at and end of the device. In one position, a sliding swivel lock permits rotation of the swivel and in a locking position it prevents relative rotation by engaging one of several slots in the swivel. The slots are located so that the cleaning head can be centered (perpendicular) relative to the device or held at an oblique angle as may be desired for cleaning corners or other tight spaces.

Abstract: A trigger actuated aerosol spray cleaning device having a cleaning head mounted by a quick disconnect coupler to be independently pivotal about at least two axes. In one form, the coupler has a body with a socket receiving a plug end of the cleaning device which is retained by a button actuated, spring biased latching ring preventing axial separation from the coupler until the button is depressed. In another form, spring biased opposing jaws releasably clamp the head to the device. A swivel member pivotally mounts to either the coupler body or opposing jaws along one axis and to the cleaning head at a second axis. The swivel action in either case can be temporarily disabled by a sliding locking feature.

Abstract: An inlet construction is provided which is particularly useful in a spray arm for a dishwasher. The inlet is formed of a circular opening in a bottom wall of the spray arm and a flat plate positioned within the hollow arm, above the opening and generally perpendicular to the direction of the liquid jet directed at the underside of the arm. The plate is held in place by being pressed against a plurality of spacers formed on the bottom wall of the arm by resilient fingers positioned adjacent to each of the spacers. The liquid jet strikes the plate and the liquid is forced radially outwardly into the arms of the spray arm to be ejected from openings in the spray arm.

Abstract: A washer is described for cleaning the interiors of tanks that hold milk, beer, chemicals and so on. A body 2 reciprocates relative to a substantially surrounded and relatively fixed piston 19. The body 2 oscillatably supports three nozzles 7 each of which is movable through an arc of 60.degree. and which arc is angularly spaced from those corresponding to the other two nozzles 7 by further angles of 60.degree.. However, the body 2 and nozzles 7 are also indexed, during operation, in steps, around a further axis which is perpendicular to, and offset from the axis of oscillation and which substantially corresponds to the longitudinal axis of the tank washer itself. Thus, each nozzle 7 cleans not only an arc of 60.degree. but rotates that arc through 360.degree. so that the whole of the interior of a tank is both washed and substantially rinsed by the three nozzles 7.

Abstract: An improved rotary drive sprinkler is provided for driving a sprinkler spray head in a rotary stepping motion to deliver irrigation water over a prescribed terrain area. The rotary sprinkler comprises a pop-up stem assembly carrying the spray head and movable within a sprinkler housing between a normal retracted position and an elevated spraying position when water under pressure is supplied to the sprinkler housing. During operation, the water flowing through the sprinkler housing powers a piston drive assembly including a spring-loaded drive piston which is alternately subjected to a predetermined pressure differential and normalized pressure to displace the piston in a reciprocating manner. The drive piston is coupled to a motion converter assembly for converting the reciprocal motion of the drive piston to an oscillatory rotary motion which is coupled in turn via a reversible one-way clutch assembly to the pop-up stem assembly.

Abstract: A sprinkler assembly having a discharge nozzle for discharging water at a substantially constant volume and velocity driven rotatably about a vertical axis by a water turbine and gear drive for rotating said nozzle at varying rotational speeds in each cycle of rotation for varying the quantity of water discharged along the radial land areas extending from the axis of rotation as the length of the radial land area varies when irrigating a non-circular land area. A movable diffuser is mounted on the nozzle and is drivingly connected with the gear drive by a cam arrangement to vary the radial length and pattern of discharge of water corresponding to the rotational speed of the nozzle with the greatest radial length of discharge of water occurring when the nozzle is travelling at its slowest rotational speed.

Abstract: A rotary spray arm structure for a dishwasher or the like rotatable about an axis of rotation, the spray arm structure having an entrance passage coinciding with the axis of rotation for receiving a pressurized column of liquid, the entrance passage opening to a hollow interior of the spray arm, and a plurality of nozzles spaced along each hollow arm of the spray arm means with each nozzle having an entrance end at the hollow interior and an exit end for discharging the liquid, the hollow interior in each arm constricting from adjacent the axis of rotation to adjacent the outer end of each arm and liquid supply ramp means leading from the hollow interior of each arm to the inner entrance end of each nozzle with each ramp comprising a groove angled outwardly toward its nozzle.

Abstract: A water sprinkler comprising a sleeve portion (1, 20, 21) fixedly mountable on a water supply pipe, a rotatable member (2, 22) rotatably mounted on the sleeve, a nozzle device (3, 23) fixedly mounted in the upper portion of the sleeve so as to be coaxial therewith, and a baffle (4, 25) located within the rotatable member, the baffle member being coaxial with the sleeve, the rotatable member having pivotally mounted thereon at least one swing arm (8, 28) carrying at least one shaped member (9, 29) adapted, in use, to lie in the path of water issued from the nozzle and deflected by the baffle.

Abstract: An end gate attachment for use on a manure spreader in which the end gate has forwardly extending arms positioned over the upper edges of the manure spreader box. The arms are hollow and open downwardly so as to encompass hydraulic cylinders that extend between the upper edges of the box and the arms for purposes of raising and lowering the arms and the gate.
