v This iiiivention relates to a feed -mechanism,:andit is particularly an object of the invention to provid des gned. and jadapted for use n connection with a dusting mechanism for vide a device of this kind embodying an agiitating Wheelworking within a hopper and whichwheel is of such construction toeliminate the liability, ofthe dust within the hopper,

to mai ntain ing' of the" hopper. '1

A further objectof the invention is to provide a mechanism of this kind including a 'plateadj ustable with respect'to the discharge opening of the 'liopper'forregulating and proaches stopping up."

controlling the discharge from said hopper andwherein is employed an agitatingwheel which, during this" rotation, "closely apthe dischargeopening of the hopper to thereby prevent said opening from A still further object of the invention is to a provide an'apparatus of this kind wherein the supply hopper a there is provided below the discharge from container to collect dust 'whichwould otherwise probably be lost upon slowingup or stoppin'gof the dusting apparatus. v The invention consists in the details of construction and'in the combination and ar-' rangement' oftheseveral parts'of my im- 7 whereby certain important advantages are attained an'd the device rendered "simpler yless expensive and otherwise more convenlent and advantageous I i r openings for use, as w ll beliereinafter more fully set forth.
