A spray nozzle for discharging liquid in a spray pattern onto a ground surface includes a structure to obtain optimum diffusion of the liquid droplets in the spray pattern. The spray nozzle includes a diffuser plate having an upwardly extending diffuser blade thereon. The diffuser plate and blade are adjustable vertically and longitudinally in the discharge end of the nozzle to enable variation in the diffusion characteristics of the liquid discharged from the nozzle. The diffuser plate is also removable for replacement with other plates having alternative diffuser blades. The structure enables variation in the spray pattern of the liquid passing between the diffuser blade and the inner surfaces of the side walls of the nozzle by changing the location of the diffuser plate and blade in relation to the discharge end of the side walls of the nozzle or by using another plate having a different diffuser blade for different diffusion characteristics.

A spray nozzle of two piece structure threaded together and including a fitting for mounting on a pressurized liquid supply pipe and including an orifice controlling liquid flow to a one piece molded nozzle of plastic material screw threaded onto the fitting. The nozzle includes spaced longitudinal side walls interconnected by a top wall and a bottom slot. A diffuser plate or blade is mounted between the side walls at the discharge end of the nozzle. The side walls of the nozzle converge from the inlet end of the nozzle toward the nozzle blade or plate at the discharge end. Each side wall converges toward the center line of the nozzle at an angle ranging between 1 and 3. A thin metal plate forms a closure for a major portion of the length of the bottom slot with a rearward end having an air inlet below the orifice in the fitting to draw air into the nozzle as liquid exits the orifice into a larger volume area at a reduced pressure. The other end of the plate terminates in adjacent but spaced relation to the diffuser blade.

A reversing switch and more particularly a diaphragm operated electrical polarity reversing switch which has general utility but in the application the reversing switch is disclosed for use in combination with a vehicle mounted spray device including a discharge nozzle which may be used for applying chemicals, liquid fertilizers and other liquids such as when applying such materials alongside of roadways to effectively apply liquid throughout the width of the road right-of-way in which spray nozzles are mounted adjustably on a pivotal arm-type support assembly at the right front of a vehicle and a control arrangement is oriented in the cab of the vehicle to enable the vehicle operator to control the spray apparatus. A diaphragm is communicated with a pressurized supply line with the diaphragm being responsive to pressure in the supply line together with a control valve to direct flow to one of a plurality of different sized nozzles in order to maintain a constant pressure of liquid at each nozzle with any temporary variation in the pressure caused by switching from one nozzle to another being promptly corrected thus providing a constant flow rate and constant width of discharge of liquid from the nozzle.

A window having a fixed sash which can be easily removed and replaced for cleaning the transparent windowpane or for replacement of the windowpane in the event of breakage. The fixed sash of the window is usually associated with the upper portion of a window frame with a movable bottom vent being mounted in the window frame for vertical movement between a lowered closed position and a raised open position with a latch mechanism securing the movable vent in closed position. The window frame which receives the fixed upper sash and the movable lower or bottom vent is secured to an opening in a building wall in the conventional manner of prime windows and may be in the form of vertical and horizontal frame components constructed of extruded aluminum structural members with a centrally located meeting rail also constructed of an extruded aluminum rail rigidly fixed together in a manner to form a window frame with the fixed sash and movable vent being mounted in the frame in a manner that the movable vent can be moved to an upper position and removed from the frame with the fixed sash including unique retaining devices along the side and top rails to securely retain the frame of the fixed sash in the window frame but yet enable simple and easy removal thereof without requiring the use of special tools and without requiring any modification of the window frame.

A spray nozzle to discharge liquid material in a pattern which has the same quantity of liquid material in each increment of the pattern. The nozzle may be used in various orientations in which a supply of pressurized liquid is available with the liquid being discharged generally in a lateral direction in relation to the path of movement of the nozzle thereby rendering the nozzle quite effective for use in discharging liquid fertilizer, growth retardant, insect sprays, orchard spray material and the like in an effective manner. In one embodiment of the invention, a nozzle is provided with a discharge passageway, a downwardly opening, inverted U-shaped extension of the passageway and a curved blade diffuser in the inverted U-shaped extension of the passageway to break up the liquid flow into droplets and to cause the droplets to be discharged in a lateral pattern so that a substantial equal quantity of liquid material is discharged in each increment of the path being traversed by the nozzle. In another embodiment of the invention, an additive injector is incorporated into the nozzle which enables a controlled quantity of liquid material to be injected into the main flow of liquid being discharged with the diffuser effectively serving as a mixer for the additive and the liquid discharged from the nozzle.

A sprinkler for irrigating a square or other polygonally-shaped land area with the sprinkler including a unique structure which will accurately distribute an equal quantity of water on each increment of land area being irrigated. The sprinkler includes a rotatable nozzle in which the speed of the nozzle is varied by a gear drive mechanism which receives its power from a water powered turbine device. The rotational speed of the nozzle is slower when irrigating corner area of the land area being irrigated and faster when irrigating intermediate straight-sided portions of the land area with the nozzle including a diffuser which becomes operative to reduce the length of trajectory of the water being discharged when the sprinkler is irrigating the intermediate straight-sided portions of the land area being irrigated.

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. The diffuser includes a blade movable laterally of the nozzle to split the stream of water as it is being discharged and a radiused groove formed in the upper surface of the water passageway in the nozzle opposed relation to the tip of the blade with the blade causing back pressure with part of the water being caused to flow around the periphery of the groove and to be discharged downwardly across the water passageway for diffusing the stream of water and varying the pattern of water discharged from the nozzle. Ridge-type baffles are formed on opposite walls of the passageway downstream of the blade to breakup the stream of water into a finer spray for improving uniformity of distribution.
