Plant dusting apparatus

Claim 2

Apparatus as defined in claim 1 wherein said one end of said material discharge conduit and said air vent conduit terminate in coplanar relationship relative to one another and in spaced relationship relative to said removable closure means.

Claim 3

Apparatus as defined in claim 2 wherein said removable closure means comprises a cylindrical cap plate having a continuous flange projecting from a side thereof for releasable connection on said other end of said receptacle.

Claim 4

Apparatus as defined in claim 3 wherein said releasable connection comprises friction means.

Claim 5

Apparatus as defined in claim 3 wherein said other end of said material discharge conduit extends transversely through and beyond said air chamber closure wall and is connected with said air pump means inlet and supports said air pump means thereon.

Claim 6

Apparatus as defined in claim 5 and valve means controlling the flow of air through said opening formed in said closure wall.

Claim 7

Apparatus as defined in claim 6 wherein said valve means comprises a plate pivotally mounted on said closure wall for selective swinging movement across said opening.

Claim 8

Apparatus as defined in claim 7 wherein said material discharge and air venting conduits extend parallel to one another and are disposed in offcenter but parallel relationship relative to the longitudinal axis of said receptacle.

Claim 9

Apparatus as defined in claim 7 wherein said material discharge conduit is substantially coaxially aligned with the longitudinal axis of sad receptacle, and a plurality of air venting conduits are provided in tangential engagement with said material discharge conduit.

Claim 10

ApparatuS as defined in claim 9 wherein the other ends of all of said conduits extend beyond the adjacent end of said receptacle.

Claim 11

Apparatus as defined in claim 1 and Apparatus for dusting plantlife with a dry powdered, particle, or particulate material and comprising: an elongated handle having a pair of opposed ends; a mounting plate having a pair of opposed sides with one end of said handle being fixedly connected on one side thereof; a substantially hollow material receiving receptacle having a pair of opposed ends with one of its ends fixedly connected on and sealed against the other side of said mounting plate; removable closure means extending across the other end of said receptacle; means air venting said receptacle to the atmosphere; a material discharge conduit having a pair of opposed open ends with one of its said ends in communication with said receptacle and the material therein; pump means including a material discharge nozzle at one side thereof, and a material inlet opening connected with the other end of said material discharge conduit; and means for actuating said pump means to draw said material from said receptacle and to broadcast said material therefrom through said nozzle; means providing an air chamber for said receptacle, said air chamber means comprising a substantially cylindrical closure wall having a continuous flange at a peripheral marginal edge of projecting laterally from a side thereof and secured to said one side of said mounting plate to define said air chamber therebetween; said closure means comprising a substantially frustoconical hollow sidewall, an end wall disposed substantially in the plane of the frustum of said sidewall, and a flange projecting from the base end of said sidewall for connection to said other end of said receptacle; said other end of said material discharge conduit extending transversely through and beyond said air chamber closure wall and connected with said air pump means inlet to support said air pump means thereon; said material discharge conduit being substantially coaxially arranged with respect to the longitudinal axis of said receptacle; said venting means further including a plurality of elongated conduits having opposed ends with one of their respective ends opening into said receptacle and their other respective ends opening into said air chamber, said one ends of said plurality of conduits terminating in substantially coplanar relationship relative to the adjacent end of said material discharge conduit; and said last-named ends of all of said conduits having an axial length greater than the axial length of said receptacle with said adjacent ends of all of said conduits extending beyond the adjacent end of said receptacle.
