On the opposite end of the hollow pole handle is a trigger. When the trigger is activated, an internal trigger stick is moved down through the hollow pole, thereby causing a ā€œCā€ shaped piece to move upward. This upward movement pushes on a hard flat disk. The movement of the hard flat disk causes pliable cap center to move. The gravity flow of liquid herbicide from a liquid herbicide container causes the liquid herbicide to move through a tube and nozzle assembly. The adjustable width protective shield over the nozzle prevents overspray and accidental contact of the liquid herbicide on healthy desired vegetation.

  • Patent number: 7654476
    Abstract: A broadcast spreader with a movable deflector is disclosed. The spreader distributes particulate material by a rotating plate which when operating, always impacts material on the deflector. The deflector and a mounting track prevent dispensing material impacting on a user of the spreader, and when the deflector is extended, also prevent dispensing material distributing to the right side of the spreader. In this way, lawns which abut a driveway or a flowerbed may have material distributed on them without also depositing material on the driveway or flowerbed. Further, the deflector is integral with a port closure panel which automatically reduces, in a proportional manner, the flow of particulate material as the deflector is extended.

  • Patent number: 6443372
    Abstract: An adjustable sprinkler nozzle includes a cap with a first spiraling face, the bottom edge of which is provided with a stepped flange. A body that forms a nozzle orifice with the cap is composed of upper and lower bodies coupled together using high frequencies such that the upper body, during injection molding, is formed with a third spiraling face that extends from an inner tubular wall thereof to correspond to a second spiraling face on the outer periphery. The inner diameter of the third spiraling face can just be fitted into by the larger outer diameter of the stepped flange of the cap. Furthermore, a longitudinal drop face formed between the high and low planes of the third spiraling face is provided with a first stop piece projecting upwardly from a highest point thereof The stop piece is inwardly provided with an inclined face. The inner wall surface of the third spiraling face is provided with a second stop piece relative to the position of the first stop piece.

  • Patent number: 6336599
    Abstract: A spray shield apparatus for shielding against spray from a sprinkler. The spray shield apparatus has an elongated support rod capable of being anchored relative to the sprinkler. A pair of baffles are mounted to an upper shank of the support rod with least one baffle having a pivot end which pivots to different angles relative to the other baffle. Additionally, flexible tabs which extend from the upper shank are preferably used to releaseably secure the pivoting baffle(s) at the desired angle. The flexible tabs are capable of engaging and disengaging notched grooves located on an inner surface of the pivot end.

  • Patent number: 6148743
    Abstract: An air nozzle for introducing secondary air into a furnace and including a housing provided with an inlet at one end thereof for receiving air and an outlet at the other end thereof for discharging the air. A damper is disposed in the housing in the path of the air for splitting the flow of the air into two flow streams which extend to different areas of the furnace and is adapted for pivotal movement in the housing to vary the amount of air flow in each of the streams and the discharge angle of one of the streams.

  • Patent number: 6016976
    Abstract: A venting nozzle has a housing having an air inlet through which an air flow enters the housing. The housing has an outlet through which the air flow exits. The outlet has deflection elements for deflecting the air flow. Parallel flaps are pivotably connected in the housing for shutting off the air flow. Meshing gear segments are positioned in the housing and connect the flaps. The meshing gear segments are arranged outside the air flow. A rotary control is coordinated with one of the flaps for controlling positioning of the flaps.

  • Patent number: 5392990
    Abstract: A double-nozzle deluge gun has a pair of nozzles arranged side by side rotatably on a rotatable table and an inter-nozzle control unit for adjusting the inter-nozzle angle measured between two lines obtained by projecting the radiation center lines of the nozzles onto a horizontal plane. Each nozzle has a deflector which is positioned in front of the nozzle during the very short range mode. Each deflector has a side cover which prevents water having passed through the deflector from excessively spreading sideways. The inter-nozzle angle and the water pressure are adjusted in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern in any range. Thus, the double-nozzle deluge gun can be controlled in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern having an appropriate width in any range.

  • Patent number: 5335859
    Abstract: An improved irrigation system for low-volume flow to individual plants or trees is presented. The system involves a detachable irrigation emitter with a flow deflector. In addition, an easily interchangeable dual flow pattern adapter is presented that can be slipped over the irrigation emitter in two different ways, thus providing two different deflection faces to produce two different flow patterns. Thus, with only one adapter, three distinct spray patterns may be selected at each plant site with much less time and labor than in previous systems. In a further embodiment, flow pattern adapters with three and four deflection surfaces are described, offering the choice of four and five distinct spray patterns at each plant site, respectively.

  • Patent number: 5234169
    Abstract: An improved sprinkler comprises a nozzle body having a nozzle received in a recessed seat provided in a peripheral wall of the nozzle body. The nozzle body has a rotatable upper cover. A cam surface is formed on the cover and extends down into engagement with the nozzle. The cam surface is shaped to push the nozzle at least partially out of its seat during rotation of the cover to allow the user to be able to grip the nozzle and complete its removal by pulling outwardly on the nozzle. The cover also includes a locking rib which can be brought to bear against the nozzle when the nozzle is fully received in its seat to help retain the nozzle in place. Desirably, the cover also includes a radius adjustment screw which is located in front of and spaced away from the front end of the nozzle such that the screw does not in any way engage or bear against the nozzle to prevent damage to the nozzle from the screw.

  • Patent number: 4991780
    Abstract: A duocone spray nozzle having two concentric peripheral orifices which will produce two hollow spray cones, one inside the other. Each orifice size is varied by employing its own spring and each spring acts independently and is compressed under its own pressure drop. The springs are designed so that the inner spring will open the inner orifice at a pressure drop which is lower than the pressure drop occurring at the outer office. Therefore, the inner spray cone occurs before the outer spray cone. When the pressure drop at the inner orifice exceeds a predetermined value, the outer orifice opens and after this occurs there will be two spray cones. A hold structure aids in separating the two spray cones.
