CROSS-REFEREN CE T O RELA TED PATENTS This application is a reissue of US. Letters Patent No. 3,308,774, filed May 16, 1966, which is in turn a continuation of my parent application Ser. No. 338,927, filed Jan. 20, 1964, and now abandoned.

This invention relates to a new and improved seed planter of the type intended to be attached to the usual tractor or other draft vehicle and which will deposit seeds into a furrow formed in the ground.

The preparation of a field for planting requires a large amount of hard work and expense, the latter being incurred by the cost of fertilizer, seed, equipment and expenditure of time. Therefore, it is necessary that the actual planting of the seed be carried out such that the farmer can rest assured that he has an even planting. If the seed planter should skip and leave areas not planted, then a great deal of work and money have been wasted and unfortunately this is not known until the plants break ground, at which time it may be too late to replant. On the other hand, should the seed planter drop too many seeds, a large amount of additional work and expense is involved to thin out the plants to the desired number.

Seed planters of many various types and designs are now presently on the market but none of the known machines can perform to deposit a given number of seeds in hills or spacings along a furrow without some skipping or depositing extra seeds. Therefore, it is a principal object of the present invention to provide a seed planter which will overcome the weaknesses of the present planters.

Another object of the present invention is to provide a seed planter which will deposit a given number of seeds into the ground at a given distance apart and wherein the number of seeds deposited can be controlled at the will of the operator.

Still another object of the invention is to provide a seed planter which will eliminate skipping during the deposition of the seeds so that the farmer or operator of the planter does not have to worry as to whether or not the area which he has covered is correctly plan-ted.

Still another object of the invention is to provide a seed planter comprising a hopper and rotating disc type seed distributor which comprises a single compact unit.

A further object of the invention is to provide a seed ice planter of few moving parts so there is very little possibility of mechanical failures.

A further object of the invention is to provide a seed planter which may be used to plant seeds of various sizes without the necessity of a large amount of auxiliary equipment.

Still a further object of the invention is to provide a seed planter wherein the rotary disc type distributor section is easily removable from the frame so the discs can be changed if necessary.

These and other objects of the present invention are set forth in greater detail in the following description having reference to the attached drawings wherein an illustrative embodiment of the invention is shown.

- In the following description right-hand and left-hand reference is determined by standing to the rear of the planter and facing the direction of travel.

Now, having more particular reference to the drawings, an illustrative embodiment of the new and improved seed planter of the invention is generally indicated at 10 and includes a frame 11 and a seed distributor 12.

As best shown in FIGURE 1, the frame 11 includes upper structural members 13 and 14 which extend rearwardly then downwardly in parallel relationship. A ground engaging wheel 16 is rotatab-ly mounted between the ends of the downward extending portion of the members 13 and 14 on an axle 15 supported by these members.

Mounted between the forward ends of members 13 and 14 there is the usual hitching member 17 for connecting the planter 10 to a suitable tractor or draft vehicle. Other connections to the tractor are indicated at 18 and 19 but as these connections form no part of the present invention, no further description is believed necessary. Located directly below the members 13 and 14 are lower parallel frame. members 20 and 21. Member 20 lies in the same vertical plane and extends in the same direction as does member 13 and member 21 lies in the same vertical plane and extends in the same direction as member 14.

Both members 20 and 21 are'somewhat shorter in length than members 13 and 14 and the front ends of members 20 and 21 are connected respectively to members 13 and 14 by vertical frame elements 22 and 23. The rear ends of members 20 and 21 are connected to members 13 and 14 in a like manner by vertical frame elements 24 (FIG. 3) and 25.

Located between elements 22 and 24 is a hopper support member 26 which is securely fastened to the upper and lower frame members 13 and 20. In a like manner, a second hopper support member 27 is located opposite support 26 and is fastened to upper and lower members 14 and 21. Both support members extend upwardly a for a portion at the bottom thereof when the seed distributor 12 is mounted within the frame 11. The portion which is not enclosed forms an opening 62 through which seed delivered by opening 39 to the interior of the distributor 12 may be dispensed to the ground. A second compartmented wheel 63 is secured to a shaft 64 rotatably supported in a pair of plates 65 such thatthe upper edge of the dividers 66 of the wheel 63 will pass into the opening 62 and extend thereabove. The wheel 63 acts as a valve gate to receive seeds from the first compartmented wheel 45 and delivers them to the ground through an opening 67 provided within a runner 68 extending below the frame 11 and secured thereto by any suitable means.

A belt 69 connects the pulley 42 to a pulley 70 secured to the ground wheel 15 so that the wheel 45 and disc 49 are rotated as the planter is drawn over the ground and rotation of the wheel 45 causes rotation of wheel 63. This is accomplished by each divider 47 as it passes opening 62, contacting one of the dividers 66 of wheel 63 extending above the opening to rotate the Wheel 63 and discharge the seeds therefrom.

A sheet metal cover 71 is provided for the outer face of disc 49 and is held in place by suitable fastening means to frame 11. The cover 71 is formed with a centrally located outwardly bent portion 72 forming a boss which covers the ends of shaft 41 and is further provided with an annular outwardly bent portion 73 located adjacent the periphery of cover 71. The annular portion 73 lies directly over the recess 53 in disc 49 when the cover is secured in place and forms therewith a hollow area to receive seed from the seed boot 30. The seed is fed by gravity from the hopper 28 through boot 30 which is secured in an opening 74 at the bottom of the annular portion 73. The seed will feed into said area formed by the portion 73 and recess 53 until it reaches the level of opening 74 at which time no further seed will enter into the space between these members.

When a field is to be planted with a given crop, the farmer will choose a disc 49 having a given number of openings therein, the number of openings being selected in accordance with the gearing ratio available from pulleys 42 and 70 and the speed of the tractor. All these factors will be computed in advance and be furnished tothe user of the planter. It will be understood that a single disc 49 with a given number of openings will perform the dispensing of a number of diflerent size seeds and will not require the disc 49 to be changed except when seeds of extreme differences in sizes are to be planted. In addition, the ability of the user to change the size of the compartments in wheel 45 along with the other controllable factors set forth above permits the deposition of seed to be controlled completely both as to the number of seeds deposited and the spacing of the seed within the furrow.

Once the disc 49 is selected and the seed distributor is positioned on frame 11 with the planter attached to a draft vehicle, the hopper may then be filled with a quantity of seed which will feed by gravity through the boot 30 into the area formed by portion 73 of the cover 71 and the recess 53. The seed will continue to fill this area until the mouth of the boot is reached by the seed level.

As the planter is drawn over the field, the disc 49 will rotate in the direction indicated by the arrows in FIG- URES 4, 5, and 7 and each of the opening 52. and finger portions 57, 58 will successively [pass] move in a path part of which passes through the supply of seed at which time the gripping portion of fingers 55 will be opened to receive a seed. The opening of the fingers is accomplished by the leg 61 of fingers 55 contacting the front end 37' of the cam surface 37 to raise the legs 57 and 58 of the fingers with respect to the surface 38 of plate 34. When the gripping portion of the finger is in this raised position, a wedge-shaped seed pocket or V is formed by the finger 55 and the surface 38 which will normally receive a seed in the bight thereof as the fingers pass through the seed.

If the seed being planted is somewhat fiat in nature such as corn, then the bevel 54 will aid to turn the seeds to assure that the seeds will be presented to the gripping portion of the finger while lying on one of their flat sides. Such positioning of the seeds in conjunction with the roughened under surface of the finger 55 permits the gripping portion to more firmly hold the seed during its travel to the discharge opening 39.

After the leg 61 of the finger 55 passes off end 37" of cam 37, the second engaging means or fingersecurely holds the seed against the first engaging meansor surface of plate 34 and holds the seed in continuous sliding contact initially against the first bearing surface 38 and subsequently against the second bearing surface 40a for a sufifciem time to permit excess seed not gripped by the finger portions 5 7, 58 to gravitate out of the seed pockets during the rotation of the disc 49 around to the discharge opening 39. [The] Should a plurality of seed be retained in the seed pocket, the recessed portion 40 just preceding the discharge opening 39 assures that only a single seed from each finger will be delivered to the opening. Should two seeds or more be held by the gripping legs 57, 58 of the finger against the surface 38, the outermost seed located in the bight of V will be released as soon as it passes over the front edge of recess 40. This happens because the rearmost seed is still held between legs 57, 58 and surface 38 so that the gripping action of the finger 55 is released with respect to the front seed as soon as recess 40 is encountered and the seed will drop away by gravity before opening 39 is reached and return to seed supply through the annular recess 53.

When finger 55 carrying a seed therewith reaches opening 39, the seed is impelled by the spring action of the finger into the opening to pass into the interior of thehousing.

Within the housing, the compartmented wheel is rotating in unison with disc 49 and one of the compartments of the wheel receives the seed as it is discharged into the opening 39. The seed is then carried by the wheel 45 tothe opening 62 where it is deposited into one of the compartments of valve wheel 64; and as this wheel is rotated as previously described, the seed or seeds are dropped through the opening 69 in runner 68 into the furrow.

It will be seen that the number of seeds dropped into the furrow at each spacing can be controlled by rearranging dividers 47 to vary the size of the compartments of wheel 45. For instance, if the disc 49 contains eight of the openings 52 and dividers 47 are placed at positions corresponding to the first opening and the fifth opening, then four seeds would be delivered to each spacing along the ground. On the other hand, if four dividers were used with wheel 45 and placed at positions corresponding to the first, third, fifth and seventh openings, two seeds would be delivered to each spacing. v

It will be readily understood that the present invention provides a planter which will assure the farmer that the field will be covered without any skipping occurring and be further assured that the correct number of seeds are being planted in the furrow.
