  • Publication number: 20170356560
    Abstract: A tank fill adapter device for a portable fluid tank provides a connection between an inlet collar of a tank and a supply pipe for filling the tank with a fluid that introduces an air gap into the connection. An annular mounting flange mounts against the inlet collar using a fastened connection. A pipe supporting portion protrudes upwardly from the annular mounting flange for supporting an open end of the supply pipe spaced above the inlet collar. An outer annular baffle protrudes downwardly from the annular mounting flange for being received into the tank through the inlet collar and an inner annular baffle is supported within the outer annular baffle to define a generally annular space between the outer and inner annular baffles which remains in open communication at a bottom end thereof with an interior of the tank.

  • Patent number: 5156338
    Abstract: A spray shield for a field sprayer includes a front skirt and a rear skirt each extending along a plurality of nozzles of the field sprayer. For each nozzle there is provided a dome-shaped enclosure which is attached to the front and rear skirt and extends therefrom upwardly toward the nozzle so that between each enclosure and the next there is defined a V-shaped through which prevailing winds can pass. The dome enclosure terminates at an edge surrounding an opening with the edge lying in a plane below the height of the top of the nozzle so that an initial portion of the spray pattern is exposed to view above the dome enclosure while an open portion of the spray pattern is protected by the dome enclosure and by the skirts from the prevailing winds.

  • Patent number: 4775123
    Abstract: A device for holding a bag generally of the thin flexible plastic material type used for garbage bags so the mouth of the bag is held open and is held fixed to the holding device comprises a hoop or tubular member which is an upper edge which is flared on a lower edge of reduced circumferential dimension. The bag is thus passed upwardly through the hollow interior and wrapped around the upper edge so the edge of the mouth of the bag lies in the outer side of the device. Latching arrangements provided centrally of an arch portion and centrally of a blade portion of the device comprise a finger hold and a slot with the slot breaking out on the lower edge. In operation the edge of the bag is pressed through the finger hold to provide a tail on the inside of the device and then the tail is pulled against the lower edge of the device so that it enters into the slot to be clumped thereby.
