PLANTER.

Patented Feb. 20, 1906.

To all whom t may concern.-

Beit known that I, WILLIAM S. GRAHAM, a resident of the city of Canton, county of Fulton, and State of Illinois, have invented certain new and useful Improvements in Planters, of which the following is a specification.

This invention has particular reference to cotton-planters or to planters of the lister type adapted to plant either cotton or corn and the principal object is to provide means for raising and lowering the soil-cutting appliances without disarranging the pitch of the soil-cutting appliances and without weakening the draft-hitch as the cutters descend. In some planters of the lister type the plowstandard is vertically shiftable in the frame, so that the soil-cutting appliances may be raised or lowered by translatory vertical motion and without disarranging the pitch thereof but this plan is open to the objection that the resistance increases as the soil-cutting appliances move downward from the bearing of the standard in the frame, making the draft-hitch weaker as thel work becomes heavier-that is to say, the soil-cutting appliances are moved farther from the bearing of the standard in the frame as they enter the soil, and the farther the resistance or work isfrom the connection of the standard with the frame the greater the danger of breaking or straining the standard or the bearings therefor. Another plan which gives a secure draft-hitch is that of swinging the soilcutting appliances up and down with the rear end of the tongue of the planter; but inasmuch as the tongue Swings with the neckyoke bearing for a pivot it is apparent that up-and-down motion of the rear end of the tongue changes the relation of the tongue to the horizontal and that soil-cutting appliances partaking of this swing would be constantly changing their pitch or soil-entering tendency. My idea is to raise and lower the soil-cutting appliances with the rear end of the tongue, to provide a draft-hitch that moves up and down with the soil-cutting appliances, and to neutralize the tongue swing in the draft-beam and the standard by giving the beam and the standard a corresponding swing in a direction opposed to the direction of the swing of the tongue. The draft-beam connects pivotally with the 'tongue in front of the rear end thereof, so as to swing vertilever its horizontal position may be.

cally with relation thereto, and as the tongue swings up and down the draft-beam is swung with relation to the tongue to an. extent and in a direction to cause the standard to maintain a certain relation to the vertical, what- Assuming the proper position of the standard to be precisely vertical, as shown in the drawings, the compensating swing of the draft-beam is such that this position is maintained regardless of depth of penetration of the soil-cutting appliances.

Another object of my invention is to provide means for tilting the various soil-cutting appliances by tilting the frame on its axleshaft so that desirable alinement of the appliances may be obtained and maintained, and other objects wilI appear from the detailed description.

In the drawings forming part of this speciiication, Figure l is a side elevation of an embodiment of my invention, showing the different soil cutting appliances with their points in a horizontal line and in an intermediate position. Fig. 2 is a plan of the planterframe. Fig. 3 is a side elevation of rthe planter, showing the soilcutting appliances raised. Fig. 4 is a plan of a part of the planter frame, illustrating the operation of throwing the seed-dropping mechanism out of operation as the soilcutting appliances are raised to their highest positions. Fig. 5 is a side elevation of the planter, showing the soil-cutting appliances lowered to approximately their greatest depth of soil penetration. Fig. 6 is also a side elevation of the planter, showing by comparison with Fig. I how the soil-cutting appliances may be tilted on the axle-shaft to give the desired pitch or alinement to the different appliances.

A pair of wheels l are mounted on the axleshaft 2, one being attached to the shaft so as to give motion thereto. A frame composed of barsV 3 and 6 is sustained from the axleshaft through bearings 49, having the upward-extending brackets 5() and 51. The frame-bars 3 and 6 are connected together at their front ends. The bar 3 is bent across the planter at its rear end and is attached to brackets 5l, and the rear ends of bars 6 diverge from bar 3 to connect with brackets 50. Rails 7 are pivotally connected at S between bars 3 and 6, and they are suitably connected together at their rear ends. Standards 12 are secured to rails 7 near the rear ends thereof, and they are provided at their lower ends with the covering-shovels 13. A cross-shaft 9 is j ournaled in bearings attached to the planter-frame in front of the axle-shaft. A lock-lever lOvis attached to an end of crossshaft 9, and a rack 11 provides means for.

tension constitutes a slightly-longerlift-lever. i A bracket 48 `is secured to the tongue inv front of the rear end thereof. A clevis 15a is pivotally connected at 15 with the bracket 48, and a draft-beam 14 is secured at its front end to the clevis. Brackets 16 are secured to the rear end of the draft-beam. They diverge rearwardly and then extend parallel, and they are grooved in their .rear ends, as shown at 16a. The grooves are shown as slots for convenience in delineation, and they are adapted to receive the pins ,19 of thelever-frame 118. A rack-frame 31 is attached vto the upper surface of the rear end of the tongue. A lock-lever 32 is fulcrumed on the rack-frame and provided with a bent extension 33, and a bar 21 forms a stiff link between .the bent extension of 'lever 32 and the central extension 20 of the lever-frame 18..

Lift arms v22'project forward from the cross-shaft 9 outside frame-bar 3, and they extend beneath the rails 7 of the coveringshovels. The .lift-arms provide means .for ,raising the covering shovels simultaneous with the raising of the furrow-forming appliances.

AA seedbox 34 is connected with the planterframe and is provided with proper seed-,dropping mechanism. The actuating-wheel 23 4for the seed-.dropping mechanism is mounted loosely on the axle-shaft and is provided with ratchet-teeth 24'on its inner face. A iiange 25 `has ratchet-teeth to correspond with the ratchet-teeth 24, and it is `formed on the end. of a sleeve which is splined vonto the axle-g A collar 26 is fixed.on the axle-shaftl shaft. adjacent to an end of the slidable sleeve, and Ia spring27 encircles the sleeve between collar 26 and flange 25. ends forked, one end to embrace shaft 9 and the other to engage the surfaceof flan .e 25, j Alatera camV extension 30 'is formed on -lever 28, and a;

A furrow-former 35 is attached to the lower The upper end of the standard ismade in two parallel parts which straddle the tongue 4. The standard is firmly secured .to the draft-beam 14, and a brace 17a addsto the rigidity of the connection. A bracket 36 is pivotally A.connected with the standard at 37 and is ladjustably secured at 38. vThe bracket is slotted vertically, as shown by dottedlines at 39, in order l to provide a connection for thestandard of a subsoiler, and it has Y,the rearward-.extendmg curved vbeam 40, to which the seed-shank 41 and the soil-preparing shovel 4,2 are attached.

A casting 46 is secured ,to the eurvedrear extension o f frame-bar 3, andthe supportingbar 45 for seat 47 is secured to 1the casting 46. vIn this instance the furrow-former 35 is a middle breaker or double -.moldboard plow and the appliance 42 that prepares the s'oil'in the furrow for the reception o'f nthe seed is a shovel but a sweepniay be substituted for the middle 'breaker and a subsoiler .may take the place of the shovel 42 when desired.

'Thedifferent soil-cutting appliances are to Vhave the .usual .adjustment with relation .t0 the frame, so that they may ,be set to meet different requirements, and this :provision is too common and obvious to require special explanation.

A tube 43 telescopes in shank 41,*and its `mouth 44 is 7pvota'lly :attached beneath the discharge of the seedjbox.

In operationfthe main furrow 'is .formed by the middle breaker 35 ora Sweep. The supplemental furrow is formed by the shovel 42, or the seed-.bed isprepared bye Subsoiler, and the seed is covered by shovels 13. As the planter is drawn along the axle-shaft is rotated iby vmotiomderived from a supportingwheel 1 and the seed-,dropping mechanism in box 34 is rotated from `the `axle-shaft through gear-wheel 23. `The different soilcutting appliances are 4set to penetrate the desired depth. The frame is tilted .on the axle-shaft to get desired Aalinement, and the team-hitch is made with ythe draft-beam '14 through clevis 15a. The tongue stays the front part of Ithe frame against sidewise swing, and vit carries thehfront endof thedraftbeam up andfdown as i-t ,rises and falls. The rear end of the tongue -isunder the vcontrol of the central extension20 of ythe lever-frame I18, and the ,rear end of the draft-,beam is ,under the control ofthe side textensions 16 of the The lever that controls the tongue is longer than the lever that lcontrols the draft-beam. vThe levers swing in unison and to the same degree of circularmotion IOO IIO

and so the rear end of the tongue is carried faster and farther with any movement of the lever-frame than is the rear end of the draftbeani. The variance in the motion of the draft-beam with relation to the tongue is sufficient to neutralize the swing of the tongue and hold the standard in a vertical position. (See Figs. l, 3, and 5 of the drawings.)

I/Vhen the soil-cutting appliances get out of proper alinement through raising or lowering the front end of the tongue or through any other disarrangement of proper conditions, the lever 32 may be swung backward or forward and the planter-frame may be tilted on the axle-shaft until the proper alinement is restored. In Fig. 6 the frame is shown tilted lout of proper alinement; but the result of the tilt and the means for effecting the same are shown, and it is obviously but a matter of intelligent manipulation of the lock-lever 32 to get the desired alinement. The adjustment of the frame through locklever 32 may be made by the driver while on his seat and while the planter is moving, and when the proper alinement is obtained it will be maintained throughout the various raised or depressed positions of the soil-cutting appliances, as hereinbefore explained.
