SPECIFICATION forming part of Letters Patent N 0. 682,956, dated September 17, 1901.

Application filed May 13,1901. Serial No. 59 925. (No model.)

To ctZZ whom it may concern:

Be it known that we, AROHIBALD SATTLEY and IRA A. WEAVER, of the city of Springfield, county of Sangamon, and State of Illinois, have invented a certain new and useful Combined Lister Plow and Planter, of which the following is a specification.

This invention is exemplified in the structure hereinafter described and it'is defined in the appended claims.

In the drawings formingpart of this specivation of the rear end of the planter-frame.

Figs. 5 and 6 are details illustrative of the seedbox-chute and the planter-shank.

The frame 1 may be of any suitable conformation, and it is preferably provided on its sides with a pair of guideways, as 2. Slides 3 are fitted in the guideways 2 andprovided with spindles 4 for wheels 5. Levers 6a're fulorumed in the upper ends of the slides, and rods '7 connect the levers with. the guide ways. The levers 6 are adapted to lock'on notched segments, and it is their purpose to raise and lower thewheels with relation to the front end of the frame. A plow-beam 8 is sustained in the frame by means of bails 9 and 10, and the extended end 12 of lever 13 connects with the rear bail 10 through stiif link 11. When the lever 13 is thrown back; ward to raise the beam, the extension 12 and the link 11 swing into alinement, as shown in Fig. 2, and form a toggle jointlock. A doublemoldboard plow 17 is attached to the beam 8. Behind the plow is a subsoiler 18, and in the rear of the subsoiler is a shank 19, which is preferably provided with a soil-displacing shovel 20. At 21 is shown one of a pair of covering 4 blades, which are pivotally connected with the shank at 22, one on each side of the shank, and which are held from swinging backward beyonda certain angle by stops 23 on the sides of the shanks. The subsoiler and the shank are adjustable up and down. The shank is tubular, and the upper part of and the seedbox 29 is supported from bars 26 in front of wheel 34. The drive-shaft 30 for the seed-disk of the seedbox is journaled below the box, and it has a combined sprocket and clutch wheel 31, which is loosely mounted on the shaft and is normally held in clutch with a clutch member 42 of the shaft bya spring 44. (See Fig. 3.) A sprocket-wheel 33 .is fixed on an extended end of shaft 32, and a chain 35 imparts motion from wheel 33 to wheel 31. The pivotal shaft or spindle of the planter-frame extends above sleevev 24, as is shown at 50 in Fig. 4, and to the upper end of such shaft is rigidly attached a laterally-extending arm36. A lever 37 is pivotally connected with the end of arm 36, and it extends across the upper end of the pivotal shaft 50. A vertical hole is formed in the swinging end of lever 37 to engage a stoppin on the plow-frame, and a pin 46 (shown only in Fig. 4) extends downward from a side of the lever. An arm 14 is attached to or formed on the lift-lever 13. A rod 15 is pivotally connected with the swinging end of arm 14 and extended under the lever 37, and the rear end 16 of the rod 15 is wedge-shaped in side elevation,with the small end of the wedge presented forward. A disk 40 is formed on the'upper end of sleeve 24, concentric with shaft 50, and a notch 41 is formed in the periphery of the disk to receive the pin 46 of lever 37, as shown in Fig. 4." A lock-pin 39 entends upward from disk40 in position to engage the hole in the lever 37 when the planting mechanism is in planting position and hold the planting-frame locked against side swing. The seed-chute 28 is pivoted at its upper end so as to swing forward and back to a limited extent at its lower end, and it has a spring that tends to press its lower end forward. In Fig. 5 the pivot of the chute is shown at 28 and the spring is shown at 45.

In Figs 5 and 6 the chute 28 is shown pro vided at its lower end with a cross-bar or side extensions, as 28, which project beyond the sides of shank 19 and prevent the chute from extended end of the arm engages the clutchwheel 31 on the side opposite spring 44, as is shown in Fig. 3.

With the different parts in the position shown in Fig. 1 the pin 39 engages the hole in lever 37 and locks the rear frame against side swing, while the pin of the lever rests in the recess in the disk or top of sleeve 24. The plow, the subsoiler, and the shank 19 are in planting position, with the rear wall of the shank about in vertical alinement with the pivot of the rear frame, and the coveringblades are swung back against stops 23 by the forward motion of the plow and the resistance of the soil. The narrow part of wedge 16 is under the swinging end of lever 37, and consequently the lever is depressed. The depression of the swinging end of the lever permits the L-lever to assume the position shown in Fig. 4, and the spring 44 forces clutch-wheel 31 into clutch with shaft 30. The lower end of chute 28 is forced toward the shank by spring-pressure, and the extensions 28 bear closely against the shank. Under these conditions the wheel 34 is locked stiff with the forward frame to steady the run of the plow and the subsoiler, and the seed is conveyed to the shank through the chute. The plow cuts a wide furrow. The subsoiler cuts a narrower and deeper furrow, which is substantially closed by the pulverized soil, and the shovel 20 may be used to reopen a narrow seed-receiving furrow. As the seed is deposited the knives or coverer-blades 21 tend to draw soil toward the furrow and the wheel compacts the soil over the seed in the customary manner. The bails 9 and 10 incline backward from their pivots in the frame, and when the lever 13 is thrown backward at the ends of the field the bails swing forward, as Well as upward, and carry the plows and the shank away from therear frame 26. As the plow-beam rises the knives 21 swing clear of the ground and are carried by gravity to the position shown in Fig. 2, so as to give still greater clearance for turning around. The rearward swing of the lever 13 imparts forward motion to the wedge 16, and by such motion the swinging end of lever 37 is raised to an extent to clear the stop-pin 39, carry the end of pin 46 above the disk on sleeve 24, and to force the sleeve 48 sidewise sufficiently far to force wheel 31 outof clutch. Under these conditions the plow and its adjuncts are carried clear of the ground, the wheel 31 does not impart its motion to the planter 30, and the rear frame is free to turn with relation to the front frame. By the time the rear frame has swung sidewise sufiiciently far to carry the lever 37 off the wedge the pin 46 will be in position to rest on disk 40 and sustain the lever in a raised position, and so the clutch will remain detached untilthe pin 46 is swung over the recess 41 of the disk. It is necessary that the clutch shall be in engagement as soon as the plow starts forward in a trip across the field; but the rear frame does not always swing directly'in line with the front frame as soon as the team starts and the locking-pin does not coincide with the hole in lever 37 until the alinement of the two frames is pretty precise. To provide for this, the recess 41 is made rather long, so that the pin 46 may drop into it before the two frames are exactly in line, and the L-lever is adapted to relieve the clutch-wheel by the partial drop of the lever and permit the spring to establish driving connection with the planter-shaft. When the pin 46drops into the recess of the disk, the lever rests on top of pin 39 until the frames are in line,and the subsequent fall of the lever into engagement with the lock-pin produces no further effect on the clutch actuating mechanism.
