referring now in particular to fig1 -- 6 , the reader will readily appreciate that the present invention is embodied in an improved feed dispensing hopper 10 of the mobile or travelling type and including downwardly extending inclined walls 12 and 14 which converge toward and terminate at the mouth 15 of channel section 16 . at the base 18 of channel 16 is a plurality of feed discharge outlets 20 , 22 and 24 . to dispense feed through outlets 20 , 22 and 24 an auger mechanism 26 is disposed within channel 16 at the base 18 thereof and communicating with outlets 20 , 22 and 24 from within hopper 10 . suspended from a shaft 52 passing through hopper 10 at a substantial distance above the mouth 15 of channel 16 and extending downwardly therefrom is a feed agitator 28 which comprises a generally rigid plate or like member 30 with a network or plurality of openings 32 . as may be clearly seen in fig1 and 6 , plate 30 extends down through mouth 15 , down into channel 16 for oscillation and / or generally vertical reciprocation thereinto which precludes packing of feed therein to preclude packing of feed thereat . the lower end of plate 30 reciprocates without interference with auger mechanism 26 , coming within about half an inch of contact therewith , and has a vertical stroke of about half an inch . secured at the upper end of plate 30 is a pair of spaced - apart brackets 34 . each bracket 34 includes arcuate sleeve portions 36 , downwardly extending leg portions 38 and upwardly extending arm portions 40 . in this arrangement sleeve portions 36 loosely surround bearing members 42 , leg portions 38 are clamped to plate 30 by nuts 44 and bolts 46 , and arm portions 40 are secured together by nut 48 and bolt 50 . each bearing member 42 , which may be of low friction material , is secured to shaft 52 in eccentric relationship therewith by a set screw 54 . with a close look at the slope of the walls of channel 16 , one will readily see that the walls diverge from mouth 15 in the downward direction toward auger mechanism 26 in the form of an inverted funnel . because of the inverted funnel structure of channel 16 feed descending down past mouth 15 has the added tendency of spreading out rather than of becoming packed onto auger mechanism 26 . shaft 52 includes a power input end 56 as seen in fig2 and a power output end 58 . mounted on output end 58 of shaft 52 is a driving sprocket 60 . driving sprocket 60 drives driven sprocket 62 through chain 64 . attached to driven sprocket 62 is a shaft portion 66 of auger 26 . slack in chain 64 is automatically taken up by tension unit 68 which includes idler sprocket 70 which is rotatably supported on plate 71 pivotally secured to bracket 72 . tension spring 74 biases plate 71 and idler sprocket 70 toward chain 64 to automatically take up any slack which may develop . a canopy or hood element 76 in the form of an inverted v as seen in fig5 is shown in assembly in fig1 and 6 . canopy 76 as seen in fig1 and 6 is arranged so that downwardly diverging sides 78 , 80 provide umbrage over feed agitator 28 and shaft 52 from feed f so that feed is directed generally in the direction of arrows in fig6 on descent due to gravity . canopy 76 may extend for the full distance across hopper 10 and include flanges 82 which may be secured to hopper 10 . in assembly canopy 76 is mounted in hopper 10 so as to be clear of agitator 28 , sleeve portions 36 , and shaft 52 . an alternate form of the canopy or hood element 76 is illustrated in fig7 and 8 in the embodiment of a pyramid 176 suspended above agitator 28 and shaft 52 by any convenient member such as a rod 177 extending across hopper 10 . pyramidal canopy 176 comprises a plurality of downwardly diverging sides 178 , 180 as seen in fig7 to divert descending feed f outwardly from the central zone of hopper 10 . to allow for free rotation of shaft 52 without interference to or from pyramidal canopy 176 notches or cutouts 190 and 192 are provided at the base of canopy 176 in the areas which otherwise might interfere with shaft 52 . the notches 190 and 192 , as seen in fig8 extend at least partially around shaft 52 , but allow freedom of rotation of shaft 52 without interference from canopy 176 . from the above description of the present invention including alternative forms of elements thereof , it is believed that the reader will readily appreciate that in operation hopper 10 is driven to the left and / or right from the position illustrated in fig1 . with hopper 10 driven as noted above , shaft 52 is driven in at least one direction of travel of the hopper 10 , which may for purposes of discussion , be to the left of fig1 . in other words shaft 52 may be declutched as hopper 10 is traveling toward the right in fig1 . as hopper 10 is moving toward the left in fig1 then , shaft 52 is rotated and power is delivered to driving sprocket 60 at output end 58 of shaft 52 . drive is transmitted through chain 64 to driven sprocket 62 whereby auger 26 is rotated by shaft portion 66 on which driven sprocket 62 is secured . as auger 26 is rotated feed is dispensed through outlets 20 , 22 and 24 . while feed is dispensed as thus described , bearings 42 which are fixed to shaft 52 by set screws 54 are caused to rotate along with shaft 52 . inasmuch as bearings 42 are eccentric to shaft 52 arcuate sleeve portions 36 which loosely surround bearings 42 slide free of the rotary effect of bearings 42 , but are caused to ascend and descend with bearings 42 relative to shaft 52 . in thus ascending and descending with bearings 42 , agitator 28 is raised and lowered thereby and effects a breaking up or chopping of any feed which otherwise would tend to be compacted at or in the vicinity of the mouth 15 of channel 16 . because of the network of openings 32 in the generally rigid plate 30 of agitator 28 , feed may be worked back and forth therethrough by the oscillating and / or reciprocating motion of agitator 28 , which is caused to move as indicated by two - way arrows in fig2 and 7 . to ensure optimum dispensing of feed from hopper 10 , canopy 80 by reason of its downwardly diverging sides 78 and 80 provide umbrage for agitator 28 , shaft 52 and also mouth 15 of channel 16 to preclude packing of feed f thereabout . as seen in fig6 feed f generally descends down along the top of sides 78 and 80 of canopy 76 and follows the paths generally indicated by arrows and leaves a protected area beneath the underside of sides 78 and 80 . with the presence of canopy 76 , it is clear that no heavy packing of feed can take place around shaft 52 and agitator 28 . in an embodiment employing a pyramidal canopy 176 , it is noted that while as illustrated in fig7 the base of the canopy does not extend to the sides of hopper 10 , the base may be extended thereto . it is also noted that whereas canopy 76 is v - shaped with two diverging sides , in the alternative embodiment of pyramidal canopy , there are the two diverging sides 178 , 180 and additional diverging sides hidden from view in fig7 and partially shown in fig8 . because of the many diverging sides in pyramidal canopy 176 , the feed f diverged or deflected thereby tends to collide with other descending feed and thereby also tends to break up or prevent packing at mouth 15 of channel 16 , which funnels feed to auger 26 . canopy 176 , as may be seen in fig7 is suspended on rod 177 , for example , and is further provided with notches or cutouts 190 , 192 in the base of sides 178 , 180 and sides adjacent thereto whereby shaft 52 may turn freely without interference . it will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification .
a feed dispensing hopper of the type adapted to travel along the length of a battery cage arrangement to dispense feed into feed troughs extending along the battery cage arrangement which includes at least a pair of inclined wall portions converging to a channel portion to which feed is funneled by gravity . an auger device is provided in the bottom of the channel and is adapted to convey feed out through feed discharge outlets into the troughs . an agitating mechanism is provided to break up the feed that is funneled into the channel and a canopy or hood is disposed above the agitator to divert feed to opposite sides of the agitator and thus prevent packing of feed all around the agitator .
