( Cl. 222-239).‘ This invention relates. to a fertilizer distribu tor. An object of the invention is to provide a con struction comprising a hopper in which fertilizer to be distributed may be placed and provide means for evenly and regularly distributing and feeding the fertilizer from the hopper. Many commercial fertilizers are hygroscopic shaft M may be used to cause the shaft‘ M toro tate at a relatively slow speed but in direct rela— tion to the‘ distance of the ground traversed; On. top of” the housing It‘ there is supported? a and because of this are apt to become moist and cake or lump badly during storage. so thatat the contemplates a construction wherein the ferti lizer even though it- may have caked and become quite lumpy, is nevertheless‘ automatically re duced to a ?nely comminuted state and is evenly 15 and. regularly distributed from the? hopper through suitable outlets. Another object of the invention is to provide described while these pockets are between the out‘ lets from-the hopper. This hopper has outlets it and H2 preferably arranged at diametrically op positesidesthereof. rIfhese outlets discharge into channels or spouts l3: and i9 and‘discharge the fertilizer on to the ground to be fertilized.

Still another object of the invention is to pro ' On the shaft Hi there are mounted oneor more vide a. fertilizer distributor having relatively few lates, two of which are indicated at 23‘ and 2!. moving parts and which is readily adjustable so 25 These plates-are removably mounted on the shaft that the quantity or the rate at which the ferti 94 and arepreferably‘ keyed thereto such as by lizer is fed from the hopper may be intentionally If desired the upper end of the shaft varied at will in accordance with the desires of the operator. to be rotated by the'shaft. These plates have aligned peripheral recesses 22 which cooperate with the cylindrical wallsrof‘ the hopper i5 to 35 form a series of pockets 23/ each of which are de ment of the invention, wherein signed to receive and be?lled: with fertilizer from Fig. 1 is a vertical diametrical section through the fertilizer distributor embodying the present invention; Fig. 2 is a horizontal section taken substantially 40 upon the line 2—-2 upon Fig. 1 in the direction indicated; and-tourge the fertilizer downwardly toward the pockets. Fig. 3 is a partial horizontal section illustrating a detail of construction. _ Referring to the accompanying drawing where in similar reference characters designate similar On the inside of the hopper over the outlets there are disposed boxes 25 having tops, inner walls and ends. These boxes serve to pre 45 vent ingress to the pockets 23 as the pockets are brought into and out of registration with the out lets l6 and H.

The plates 20 and 2| are preferably, but not ing with the sides of the hopper to form pockets necessarily dome-shaped in form so that thei7 L1 adapted to be filled with fertilizer from within slope from their foundation outwardly toward the hopper and which are consecutively brought their edges. These plates rest upon a shoulder on into registration with the hopper, and spring the sh ft [4 and the shaft is preferably equipped actuated means urged into engagement with the with thrust bearing 29 supported on a central 10 walls of the hopper and the bottom for covering spide 3D in the housing. the pockets after they pass into and out of regis Th operation and advantages of the improved fertilizer distributor are as follows: The fertilizer tration with the outlets. i 2. A fertilizer distributor comprising a hopper having outlets in the bottoms of the sides there per l5. As the vehicle or tractor on which the of, a vertical central shaft in the bottom of the distributor is mounted, traverses the ground, 15 hopper, one or more superposed blades on the shaft H is rotated which brings about the rota shaft forming a bottom for the hopper, means tion of shaft M. The fertilizer in the hopper for rotating the shaft, there being peripheral is effectively steered and forced downwardly by recesses in the blades cooperating with the sides the impeller 24 and ?lls the pockets 23, during of the hopper to form pockets adapted to re the rotation of the plates 2| and 20. During 20 ceive fertilizer from the hopper and conduct it rotation of these plates by the shaft the pockets to the outlets as the shaft rotates, means closing are consecutively carried into and out of regis the tops of the pockets against ingress thereto tration with the outlets, passing beneath the as the pockets are brought into and out of regis boxes 25 which prevent further ingress of fer tration with the outlets, and an impeller on the tilizer from the hopper into the pockets while shaft above said plates rotatable by the shaft. the pockets are emptying through the outlets. 3. A fertilizer distributor comprising a hopper Each pocket 23 will, of course, contain a prede having outlets in the bottoms of the sides there termined quantity of fertilizer. This quantity, of, a vertical central shaft in the bottom of the however, may be varied by adding or subtracting hopper, one or more superposed blades on the that is to be distributed is dumped into the hop plates 2|. By adding plates 2i the height of the pockets 23 will be increased and consequently the volumetric capacity of each pocket will be shaft forming a bottom for the hopper, means increased. In this manner with a given setting of the machine the fertilizer will be constantly and evenly fed and distributed from the hopper into the spouts l8 and I9 and deposited upon or between the rows. Any tendency of the fer tilizer to remain in the pockets 23 is eliminated by the leaf springs 26 which enter the pockets and dislodge the fertilizer therefrom after the pockets are brought into registration with the of the hopper to form pockets adapted to receive outlets. for rotating the shaft, there‘ being peripheral recesses in the blades cooperating with the sides fertilizer from the hopper and conduct it to the outlets as the shaft rotates, means closing the tops of the pockets against ingress thereto as the pockets are brought into and out of regis tration with the outlets, and yieldable means extending into the pockets when they are brought into registration with the outlets for dislodging fertilizer therefrom into the outlets. . By means of the above described construction, even though the fertilizer may be hygroscopic and caky or lumpy in condition, an even feed ing or distribution of the fertilizer can be easily accomplished. The impeller 24 tends to break up the lumps and the edges of the recesses 22 tend to break down cakes or lumps by attrition during the rotation of the plates within the hop per so that the fertilizer delivered through the spouts l8 and i9 is not only delivered at a uni form rate but in a ?nely comminuted and read 45 ‘l.
