To all whom it may concern:

Be it known that I, Ina A. WEAVER, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Listers, of which the following is a specification.

My invention relates to listers or planters, and aims to accomplish a number of desirable objects or results, among which may be mentioned; first, a construction in which the plow or burster is held particularly rigidly and firmly, and, to secure this object, my improved lister has a rigid and preferablyintegral beam extending from the clevis or hitch to the rear wheels, the plow or breaker being fastened to the lower end of a standard securely and rigidly bolted or riveted to the beam and braced by means of the seat-bars; second, to secure a perfect suction regardless of how deep or shallow the operator is listing; third, to obtain a structure in which the pitch or angle of the plow remains the same with relation to the rear wheels for any depth; fourth, to provide means whereby the subsoiler or furrowopener and covering shovels or disks will be raised at the same time and approximately the same amount as the plow; fifth, to provide for independent adjustments of the subsoiler or furrow-openers, coverers, and seed-spout; sixth, to adjustably secure the seed-tube in a casting near the seed-box and arrange it so that it may slide loosely through a support on the subsoiler standard or bar whereby it may be adjusted up and down without affecting the other adjustments: seventh, to maintain substantially the same relative positions of the plow, subsoiler. and coverers regardless of the depth of plowing: eighth, to supply a strong,

asily-opcrated. and efiective lifting mechanism for the beam and associated parts: ninth, to equip the lister or planter with a simple driving mechanism for the seed-box and make the construction such that the distance between the sprocket wheel on the axle or wheel and that on the seed-shaft shall be constant, whereby adjustment or variation of the position of the parts will not. change the tension on the driving sprocket chain; tenth, to avoid the use of double chains and counterdrives; eleventh, to provide a device of this character in which the beam takes its depth immediately and does not dependentirely upon the suction for accomplishing this result; twelfth, to supply means for giving to the rear wheels any desired lead sidewise when listing on a hillside; and thirteenth, to employ an automatically-acting means to release the rear wheels and permit them to caster when he plow or burster is raised for turning.

Other advantages of my improved construction lie in the structural features and combinations of the various parts which are fully described below and illustrated on the accompanying drawing, forming a part of this specification, and whereon I have shown a preferred and desirable embodiment of my invention, like reference characters referring to the same parts throughout the varlous views.

On the drawing-Figure 1 is a perspective view of my improved lister, with the plow or burster and associated parts in lowered position; Fig. 2 is a similar view with the parts raised; Fig. 3 is a perspective view of the same machine on a larger scale, with certain parts omitted to more clearly illustrate the details of construction; Fig. 4 is a perspective view of the sprocket chain casing; Fig. 5 is a view illustrating the different positions assumable by the seed-box and its operating mechanism; Fig. 6 is a plan view of my improved adjusting means for giving to the rear wheel or wheels anydesired sidewise lead; Fig. 7 is an end elevation of the same device; and Fig. 8 is front elevation of the bent or arched axle and the lifting mechanism attached thereto.

My improved lister or planter has a rigid, integral beam 10 extending the full length of the machine from the hitch or clevis 11 to the rear wheel standard or bracket 12. The forward portion of the beam 10 is supported on a bent or arched axle 13, a hearing 14. for which is suitably mounted on the beam. As is usual in constructions of this kind, the forward carrying wheels 15 are mounted to rotate on the opposite outwardly-extended ends of the bail or axle.

Rigidly fastened to the beam 10 near its center by means of bolts or rivets is a depending standard or foot 16, to the lower 'end of which the plow or breaker 17 is secured in any approved manner. The stand ard 16 conslsts of two plates or bars fastened re Baa to opposite sides of the beam 10 and spaced apart. These plates constituting the standard are braced by the upward and rearwardly-extending seat-bars 18 on the top ends of which a seat 19 is mounted. Pivoted between the bars or plates 16 at 20 and extending rearwardly is an arm or lever 21 consisting of two bars or plates slightly l spaced apart, as is clearly indicated 111 Fig.

3. To the rearward end of this arm or lever are attached the covering disks 22 which could, of course, be replaced if desired by the ordinary covering shovels. Arm 21 is adjustably connected to a link 23 which connects the lower arm or lever 21 to an upper arm or lever 24: by means of a pivot 24*, the lever 2st being pivoted to or fulcrumed on the standard 16 at The arm or lever 2 k in turn is connected to an arm 25 on the bail or bent axle 13 by means of a curved link 26 pivoted to the two arms 24: and 25 being connected to the former by a pivot 2%. As is clearly shown in Fig. 3, the arm 25 forms part of a twoarmed casting 2T fastened to the axle 13 by means of bolts 28, the other arm 29 of the casting being connected to the forward. part of the machine by a spring 30 which assists the operator in lifting the plow and other parts of the mechanism. The upper ends of both arms 25 and 29 extend above the bearing 1 of the axle so that, as the latter is swung rearwardly to elevate the beam and plow, the ends of the arms will travel fOlVfiICllY. An upright baror support 31 passes between the parallel plates of the lever 21, being held from transverse movement by bolts 32, and at its upper end is pinned at 33 to the arm or lever 24, a plurality of holes being provided so that the depth of the bar below the arm may be readily adjusted. At its lower end this bar or support carries a furrow-opener or subsoiler 34. The seed spout 35 is adj ustably connected at its upper end to a casting 36 through which the seeds pass, its lower end being held by a clamp or ring 37 vertically adjustable on the bar or support 31 by a pin which may be passed through the ring 37 and any one of a plurality of holes in the support.

From the construction described it will be apparent that the positions of the coverers, furrow-opener, and seed-spout may be ad justed without in any way affecting the ad justment of the others, and it will also be obvious that as the arched axle or bail is swung. by a mechanism described hereinafter, to lift the beam and plow, the sul soiler, tube, and coverers will also be lifted because of the connection 26. If some such mechanism as this were not provided for lifting the subsoiler, tube, and coverers they would not be elevated to the same extent that the plow is, owing to the fact that they are somewhat nearer the rear wheels about which the machine turns during the raising or lifting of the plow.

The lilting mechanism includes a casting 38 (Fig. 8) bolted to the bail or arched. axle at and This castingSS has a notched segment ll rigid therewith and also has a bearing 42 for the accommodation of a short shaft 43, to one end of which is fastened a comparatively long operating arm or handle at equipped with a grip handle 455 connected to a dog at its lower end, which is adapted to enter any one of the notches of segment 41. A. crank arm 46 is fixed to the other end of the shaft and is connected to the beam 10 by a link J. It will be apparent, therefore, that by unlocking and moving the handle the forward end of the machine may be elevated or low cred, as desired, through the swinging of the bail or axle 13 which moves the forward carrying wheels 15 toward or from the rear wheels. It should be noticed also that arm tat, shaft -l-3, and crank arm 4A3 constitute a lever of which the shaft is the fulcrum.

The seed-box 48 and its associated mechanism, which may be of the usual and ordinary construction, are not mounted directly on the beam 10 but are supported by a pair of links or bails 4:9 and 50 of substantially the same length, whereby to give to the seed-box and its actuating mechanism a parallel motion movement.

As is indicated in Fig. 3, the seed-shaft 51 has mounted thereon or fixed thereto a sprocket wheel 52 connected by means of a sprocket chain with a similar wheel 51 loose on the axle and adapted to be connected to one of the carrying wheels so as to be rotated therewith and transmit the movement of the wheel through the chain and sprocket wheels to the seed-feeding mechanism. In order to do away with a plurality of chains and any counterdrives, and at the same time maintain a constant distance between the sprocket wheels 52 and 53, I have provided the parallel motion mounting mentioned above, and in addition it is necessary to connect the seed-shaft 51 and the axle by some rigid means such as a bar or chain-guard or cover to keep this dis tance between the sprocket-wheels constant. In the present instance, as shown in Fig. 5, I have employed a sprocket chain guard or cover illustrated in perspective in Fig. -l which is shown as having fastened to one face thereof an outstanding foot-rest 56. This guard or cover is apertured at 57 and 58 to receive the axle and seed-shaft, respectively, and this cover alone may be used to keep the shafts the proper distance apart, or any other suitable means may be employed to accomplish the same result.

In Fig. 5 I have illustrated, by full and dotted lines, a variety of positions assumable by the parts illustrated as the beam and plow are elevated or lowered by the lifting mechanism described above. Since the seedbox and its associated parts have the parallel motion mounting on the beam they always maintain a proper substantiallyhorizontal position of the parts at all elevations of the plow and beam.

It is desirable in machines of this character to provide some means for giving a side lead or inclination to the rear wheel or wheels, to make the amount of lead given adjustable so as to overcome the tendency of the machine to run down hill when working on a hillside, and to regulate the lead to agree with steepness of the hillside. Fastened to the rear end of the beam 10 by means of bolts 59 is the rear axle standard 12 having an upright or vertical bearing 61 adapted to receive the upper portion of a rearwardly-bent shaft 62, which at its lower end is supported by the axle or axles of the rear wheels 63. To the top end of the vertical portion of this shaft 62 is fixed by means of a set-screw 64 a locking member 65 having a single notch 66 adapted to receive a locking-pin or bar 67 slidably mounted in the bearings 68- of a lever 69 fulcrumed on the bracket 60 at the point 70. This locking-pin 67 is normally pressed into the notch 66 by a spring 71 surrounding the pin and abutting at one end against the bearing 68 and at the other end against a cotter-pin 72 passed through the sliding locking-pin. The bolts 59 also rigidly secure to the bracket or standard 60 a notched segment rack 73 which lies adjacent to the lever 69 constituting an adjusting handle. Pivoted at '74 on the handle 69 I provide another spring-actuated handle 75 which at its lower end cotiperates with the notches of the segment 7 3 .to maintain or look the handle 69 in adjusted position. Obviously, as the handle 60 is shifted and carries with it the locking-pin 67, one end of which is in the notch 66, the shaft 62 is shifted more or less to one side or the other, giving a lateral or side-wise lead to the rear wheels. In order that these rear wheels may be automatically released so as to be free to turn in the bearing 61 to permit the rear wheels to freely caster when the plow is lifted for turning, I connect the end of the pin 67 by means of a wire 76 and spring 76 withthe arm 29 fastened to the axle or bail. It will be apparent, therefore, that as this axle or bail is swung rearwardly to lift the beam, the arm 29 travels forwardly and through the wire 76 and spring 7 6 pulls the lockingpin 67 so as to free it from the notch 66 of the locking member 65.

The various objects of my invention set forth above, and others which will be apparent to those skilled in the art, are pro vided for in the improved form of lister shown and described. The great advantage of this device is, however, that with a construction of the simplest kind, the plow is held with great rigidity, and is therefore enabled to perform its work more satisfactorily than in those listers having no single rigid beam of the kind and associated with the other partsv of the machine as is the beam of my device.

Although I have described, with some degree of particularity, my improved con st-ruction illustrated on the drawings, it is to be understood that my invention is not limited and restricted to the precise struc-' tural details of the parts shown and de scribed, but that these may be varied within wide limits without departure from my invention.
