PLANTER.

- Application filed July 20,

My invention relates to planters and its obect is to provide improved means for control ling the seed-delivering and the soil-disposing elements of a planter.

In accomplishing the objects named I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view of a planter constructed in accordance with my invention.

Fig. 2 is a side view showing the seed-delivering and soilfmanipulating elements in lowered position.

Fig. 3 is a side view showing the plow in raised position. 7

Fig. 4 is a detail perspective view of the hitch and tongue elements, through which the soil-disposing members are controlled.

Fig. 5 is an enlarged detail perspective view of the members provided for actuating the seed-delivering element, and means for engaging said members therewith.

Fig. 6 is an elevational view of the gears for actuating the seed-delivering elements.

Fig. 7 is a detail perspective view of a novel type of gear block and sprocket, bemg a part of the means for actuating the seed-delivering element.

Referring in detail to thedrawings V The planter is shown as comprising the wheel-supporting rear frame 1 having a cross member 2, the seat support 3, the axle 4 supported in the cross member 2, and the rear wheels 5 and 6. A front frame 7 includes the side beams 8, the vertical standards 9 and a tongue 10, the frame 1 being pivoted at 11 to a hitch 12 which connects the frame 1 to the front frame 7 and the tongue 10. Carried by the frame 1 is a lever 13 pivoted 0n the frame at 14, having the hand-operable arm 15 and the foot-receiving end 16. A forwardly extending crank arm 17 on the lever is pivotally connected by a linklS with an arm 19 rearwardly extending from the tongue 10, the arrangement providing for.

the raising of the front frame 7, and the standards connected therewith, upon tilting of the rear frame around the axle by actuation of the lever.

The front frame 7 carries cross members 20 on which hoppers 21 are mounted containing dropper disks 22, Wheels 23 support 1927. Serial No 207.185.

the front end of the hopper-carrying or front frame 7; the front end of the tongue, as will be understood, being supported by the draft means, and so assisting in the support of the front frame.

Seed-delivery boots 24 are supported by the standards 9, and at the lower ends of the standards are furrow-opening shovels 25 and subsoilers 26, the subsoilers being positioned in advance of the chutes 27 of the boots.

Adjustable bracket arms 28 are secured to the standards and extend outwardly there from, and support the middle portions of covering wings 29, the forward ends of which are fastened to the shovels and the rearward ends of which are bowed to hold the furrow open adjacentthe ends of the chutes, tending to cause the earth at the edge of the furrow to fill in over the grain,

The rear wheels are aligned with the bowed wings and as the planter advances the wheels pass over the furrow to slightly pack the soil on top of the seeds dropped from the hoppers through the chutes.

A rotatable shaft 30 has its ends fixed in the dropper disks 22, the shaft extending across the machine, each end of it driving a dropper disk for delivery of the seed from the hoppers into the boots to gravitate into the furrows between the covering Win s.

I provide novel means for turning the shaft 30, and for engaging and disengaging the actuating mechanism.

The shaft 30 carries a gear 31 having a hub 82 sleeved on the shaft, the gear being slidable on the shaft and may be fixed in a desired position by a set screw 33. A gear block or gear cluster 34 is provided, having a plurality of gears 35, 36 and 37 to mesh with said shaft gear 30. The gears 35, 36 and 37 are all formed from a single casting, and all the teeth are of the same length. The gear block is rotatably supported on a right angular extensionor finger 38 carried by an arm 39 which is pivoted to a bracket 4:0 011 the 7 frame 1.

Integral with the gear block is a sprocket 41 in line with a sprocket 42 on the axle 4 of the rear frame 1, so that motion can be communicated to the gear blockfrom the sprocket 12 through. the medium of a sprocket chain d3;

The gear 35 ordinarily will have two teeth, the gear 36 four teeth and the gear 37 six teeth, so that the speed at which the dropper shaft is rotated may be varied, depending upon which of the gears 35, 36 or 37 is in mesh with the shaft gear 31. The gear 31 can be put into mesh with any one of the gears 35, 36 or 37 by loosening the set screw 33 of the gear 31 and sliding it lengthwise of the shaft 30 until it is in position to mesh with the proper gear. The structure is so provided that when the parts of the machine are in the position illustrated in Fig. 2, with the soildisposing elements in contact with the ground. the gear block is in contact with the gear 31, the sprocket chain enforcing the contact and holding the driving gears in mesh irrespective of which of the gears 35, 36 or 37 is the actual driving element, to actuate the seeddropping members.

When the rider in the seat leans backward, presses his foot on the foot-receiving end 16 of the lever and pulls back on the lever arm 15, he overbalances the rear end of the frame 1 and at the same time causes the raising of the front end thereof which, through the pivotal connection with the hitch and also through the operation of the lever crank on the tongue arm, causes the elevation of the standards 8 and the soil-disposing elements out of the ground, as shown in Fig. 3. The wheels supporting the front end of the hopper-carrying frame 7 are also lifted from the ground.

Since it is desirable that the seed droppers cease to operate while the soil-disposing elements are removed from operable position, I provide means for disengaging the actuating gear block from the shaft gear when the frame 1 is tilted to lift the standards. The disengaging means includes a bracket- 4 1 erected on a cross member 20 carried by the standards, the bracket being positioned in alignment with the arm 39, and the bracket having the slot 45 in which the arm 39 is received, so that the arm is supported on the bracket, as clearly shown in Fig. 5.

WVhen the frame is tilted as described to raise the ho pper-carrying frame 7, the bracket serves as a fulcrum. The gear bearing end of arm 39 is raised away from the shaft gear 31.

Figs. 2 and 3 show actuating arm 39 in operating and non-operating positions. It is shown that the elevating of the hopper carrying means raises the bracket 44. The arm 39 is relatively horizontal while the shovels are in the ground, the planter moving and the seed droppers operating. When the rear frame is tilted and the hopper-carrying frame is raised, the bracketin effect tilts the arm 39 so that its gear block is out of engagement with the shaft gear, and the shaft is deprived of the actuation by the gear block, and remains stationary, and the seed dropper will not operate.

The position in Fig. 3 is that in which the frame and other parts will be disposed in traveling to and from the field.
