1. An apparatus for spraying particulates from a moving vehicle comprising:
- a hopper supportable by said vehicle for storing the particulates,said hopper having a hopper discharge opening out through which said particulates can pass,a tubular barrel supportable by said vehicle,said tubular barrel having a first barrel end and a second barrel end,an air blower means operatively connected to said first barrel end for blowing air through said barrel and out said second barrel end,a conduit means for directing said particulates into the air passing through said barrel,a metering means communicating with said hopper discharge opening and with said conduit for receiving said particulates from said discharge opening and progressively delivering metered amounts of said particulates to said conduit means,a supporting means for supporting said barrel and providing for a swinging pendulum action of said barrel relative to said vehicle to help maintain the orientation of the tubular barrel as said vehicle travels over uneven and sloping terrain,said supporting means including a cradle mounted for swinging action about a longitudinal axis of said vehicle, a connecting means for connecting said barrel to said cradle so that said barrel and cradle move together, anda dampening means connected to said cradle for dampening the swinging action of said cradle and barrel.

Abstract
Upwardly diverging, transversely opposed barrels at the rear of the vehicle are supported on a transversely swingable discharge assembly. The barrels have blowers at their lower ends and receive metered amounts of particulates from a hopper through a metering device controlled by the speed of the vehicle on which the swingable discharge assembly is mounted. The assembly is so weighted that it remains upright. Split spouts on the ends of the barrels control the distribution and nozzles wet the emerging particulates. A gate selectively blocks metering of particulates to one barrel.
