SU LKY LlSTER-PLOW.

SPECIFICATION forming part of Letters Patent No. 757,994, dated April 19, 1904.

Application led April 9, 1903. Serial No. 151,831. (.No model.)

To all whom, it r11/(ty concern.-

Be it known that I, CALVIN R. DAvIs, a resident of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in SulkyLister plows andplanters; and it consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation, illustrating my improvements. Fig. 2 is a similar view of the opposite side of the machine. Fig. 3 is a top plan view. Fig. 4 is a view in transverse section. Fig. 5 is a view in cross-section through the frame, illustrating the Vmounting of the roller 19. Fig. 8 is an enlarged view of the driving-gear.

1 represents the frame of my improved lister, which comprises two longitudinal bars bowed outward between their ends. and connected at intermediate points by arched cross-bars 2, three of which latter being shown. The axle 3 is bowed between its ends and secured to the side bars of frame 1 by means of brackets 4 and U-bolts 5 and carries at each side of its bowed portion sleeves 6, having lintegral sleeves 7 at right angles thereto, in which the ends of a yoke 8 are securely bolted. The intermediate portion of said yoke is mounted to rotate in brackets 9, secured to opposite sides of the beam 17 of my improved lister or double-moldboard plow 18. One of said sleeves 6 has an integral arm 10, to which one end of a counterbalance or lifting spring 11 is connected, the other or forward end of said spring being adjustably secured in a bent bar 12, secured to one of the side bars of frame 1. This arm 1() has secured thereto an extension, which is pivotally connected by a bifurcated rod 12L with one end of lifting-lever 111, fulcrnmedbetween its ends on frame 1 and provided with a spring-pressed detent 15 to lock in any of the notches of a segment 16, secured to frame 1, and thus hold the lever and lister in any position to which they may be moved. The forward portion of plow-beam 17 when the lister is Vraisedout of the ground engages `a roller 19, supported in a frame 20, secured ;to the under face of the forward cross-bar 2,

and the rear portion of the beam engages the intermediate cross-bar 2, and its upward movement is limited thereby.

To the forward end of beam 17 a clevis is secured for the attachment of two draft-animals, and a cross-rod 21 is secured in bearings 22, bolted to the forward end of frame 1, and projects to one side beyond the same. When three draft-animals are employed, the pole-plate 23 is supported on rod 21 at one side of frame 1; but when four animals are used the pole-plate is secured on rod 22 between the side bars of frame 1, so that the pole will extend between the two teams.

To the downwardly-bent end of beam 17, which forms a standard 25, a lister 18 is secured by means of a suitable frog bolted to the standard. To the standard 25 a bracket 26 is securely bolted and provided with a slot for the reception of a bolt 27, which latter is also passed through vertical elongated slots in the subsoiler-standard 28 and a wedgeshaped plate 29 recessed to receive the standard 28 and locate its wedge portion between the forward edge of said standard and a lug 30 on bracket 26. It will thus be seen that the subsoiler can be adjusted vertically and set more or less on its point by adjusting the wedge-shaped plate 29 vertically.

An offset extension 31 is provided on bracket 26 and made with an inclined slot to receive a bolt 32, also passed through an elongated vertical slot 33 in a web at the rear of seed-dropping tube 34 and hold the latter directly behind thesubsoiler. The Lipper end of this seed-tube 34 has a forwardlyeprojecting lug 35, pivoted to the upper end of the subsoilstandard 28 by a bolt. By so mounting the seed-tube its lower end can be adjusted back and forth, and as its connection with bracket 26 is through an inclined slot this pivotal adjustment of the tube varies its depth of planting. l/Vhen the tube is set in the forward position, the seed will drop to the bottom of the furrow; but when set farther back, more or less, soil will fall to the bottom of the furrow in advance of the seed-tube, thus depositing the seed on pulverized soil. The amount of pulverized or loose soil on which the seed is deposited may therefore be regulated by adjusting the seed-tube back and forth.

Covering-hoes 36 are provided and have a series of bolt-openings at their upper ends for the reception of a bolt 37 to secure them to the lister-standard 25 and are spaced therefrom by washers 38. The intermediate portions of said hoes 36 are also provided with a series of bolt-holes for the reception of a bolt 39, passed through the bracket 26, and vspacing-washers 40 arelocated on the bolt 39 between the bracket 26 and hoes. The covering-hoes may be set to a greater or lesser depth by inserting the bolts into the different bolt-openings, so that the amount of soil required to cover the seed can be regulated to a nicety. The lower ends of the hoes are formed into twisted blades and the front edge made sharp for cutting. Said blades are twisted to the proper extent to concentrate the soil onto the seed. When the Washers 40 are removed from bolt 39, the hoes are made to cut close up to the seed-bed, but may be set farther from the seed-bed by interposing washers 40. Thus the Covering-hoes may be set to suit the different conditions of the soil so as to cover the seed properly.

On the ends of axle 3 the main wheels 4l are mounted. The boxes of these wheels are elongated on one side, as shown at 42, andl have sand-bands integral therewith. At times it becomes necessary to contract or widen the traction ofthe lister, according to whether single or double listing is done and in order to have the traction-wheels follow the ridges properly as formed by the lister-base. In order to have the-adjustment of the tractionwheels as simple as possible for the operator, I extend the wheel-boxes to one side a distance of one-half of the necessary adjustment, so that by reversing both traction-wheels 41 on the axle the proper gage is had. Thus when the wheels are in the 'position shown a wide gage is had and when reversed with the 1 box or hub extensions 42^outward a narrow gage is the result. One of these wheel hubs or boxes is made with internal notches at both ends, so that when in either position it will clutch with lugs on the hub of driving-gear 43, supported to turn on the axle. On the axle 3,-adjacent to the gear 43, a casting 44 is mounted and made with an elongated pocket in which a bearing-sleeve 45 is mounted and has lugs or trunnions 46 on oppositesides of one end supported in notches in the casting to give pivotal movement to the bearing in the pocket.. This bearing45 receives the forthereon and mounted to move longitudinally in an angular sleeve 52, in which a spring 53 is mounted and presses against the head 5la to always maintain the shaft extended longitudinally to proper working position, but permit it to contract to compensate for adjust-- ment or movement of' theV lister. In. the upper end of sleeve 52 an angle-bar 55 is secured by a bolt 54. This angle-bar 55 has a slot therein which permits of its adjustment onVV bolt 54 to regulate the tension of the spring.- The upper end of this angular sleeve 52 is connected by a universal joint 56 with the seed-3' dropping shaft 57, supported insuitable bear-f ings on a bracket 58, secured to the upper end of the lister-standard. A seed-hopper 59 is secured on bracket 58, and its dropper is oper` ated by a pinion 60 on shaft 57 meshing with a? toothed ann ular rack on the drop per. By mak- .ing the clutch-teeth 50 inclined on one side, as

shown, permits the pinion 48 to be turned in a reverse direction without operating the seeddropper, and when the listerl is elevated to its highest position the clutch member 5l will be drawn out of Contact with the teeth 50 and permit the wheels and gear to turn without operating the seed-dropping mechanism, but will automaticall y clutch when the lister is lowered.

By inclosing the spring 53 in the angular sleeve 52 I protect the same from dirt and trash, which would interfere with the perfect operation of the machine. Communicating with the outlet of the said hopper is a conveyer-tube 6l, which is pivotally secured by a bolt 62 to the bracket 58, and its lower ed rests in the upper wide endy of seed-tube 34, which permits adjustment of the latter without disturbing the feed, and an opening 63 is provided in the top of conveyer-tube 6l, so

thatthe operator can see at all times whether or not the seed are properly dropping.

A tubular bracket 64 is secured by bolts to the converging rear ends of the side bars of frame l and is supported on the wheel-stand-4 ard 65. To the bottom end of said wheelstandard an adjustable wheel-axle bearingbracket 66 is secured by a bolt passed through a sleeve on the bracket and through the lower end of the standard 65 therein. This bracket is provided with notched or toothed elongated openings 67 to receive bolts 68. passed through ears on the lower side of sand-bands 69, in which axle-stubs are secured, and on said stubs the covering wheels 7 O are mounted. Ears IOO IIO

are provided on the upper side of sand-bands 69 for the reception of bolts 71 to pivotally support the axle-stubs and permit their angle to be adjusted by adjusting-bolts 68 in the notched openings 67, and thereby adjust the angle of inclination of the coveringwheels 7 O. Suitable scrapers 7 2 are provided for these wheels 70 and are carried by aT-shaped frame adjustably secured to bracket 66 by a bolt. The tubular bracket 64 is mounted on standard 65, and the latter has a collar 7 3 secured thereon beneath bracket 64 by a setscrew 74 to limit the downward movement of tubular bracket on the standard, and a series of notches are provided in the standard, in any one of which the set-screw may be projected to secure the collar 7 3 in any position and level the lister-frame in any depth of work.

On the upwardlyprotruding end of standard 65, above bracket 64, a segment 7 5 is secured by a set-screw 76 and locked against independent turning bya key on the segment fitting a keyway in the standard. This segment has a notch 77 in its periphery adapted toreceive a lug on one end of an angular latch 78, pivoted between its ends on bracket 64, and a coiled spring 79 tends to force the latch into position with its lug in the notch 77 of segment 7 A rod 80 connects the end of this angular latch 78 with a link 81, pivotally secured to lever 14, so that when the lister is raised out of the ground at the end of a furrow or in moving the machine from place to place with the lister elevated the leveri14 will hold latch 78 out of engagement with segment 7 5 and permit the covering-wheels to freely caster; but when the lister is lowered for work the spring 7 9 automatically forces the latch into locked engagement with the segment to hold the covering-wheels true.

Suitable footrests 7 8 are secured to the frame 1 to permit the operator to brace himself in operating lever 14 and controlling the draft-animals.

The drivers or operators seat 82 is supported on a spring 83, secured to the rear cross brace or bar 2 and in convenient reach of lever 14 to control the raising and lowering of the lister.

A great many changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I do not confine myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a sulky-lister, the combination of a frame comprising longitudinal bars, cross-bars connecting the same, a lister movably connected with the frame and whose upward movement is limited by one of the cross-bars, and a roller on another bar against which the beam of the lister engages when elevated.

2. In a sulky-lister, the combination with a frame, an axle secured thereto, and wheels on the axle, of a lister, a yoke connected between its ends to the beam of the lister, sleeves on the axle to which the ends of the yoke are secured, and a lever to turn one of said sleeves and raise and lower the lister.

3. In a sulky-lister, the combination with a frame comprising longitudinal bars connected by cross-bars, of an axle bowed between its ends and secured to the longitudinal bars of the frame, wheels on said axle, a lister, a yoke pivotally secured between its ends in brackets on the lister-beam, sleeves on the axle to which the ends of the yoke are secured, an arm on one sleeve, and a lever fulcrumed between its ends and connected at one end by a link with said arm.

4. In a sulky-lister, the combination with a frame, an axle secured thereto and wheels on the axle, of a lister, sleeves on the axle, integral collars thereon at right angles thereto, a yoke pivotally secured between its ends to brackets secured to the lister-beam, and having its ends secured in said collars, an arm on one sleeve, a lifting-spring connecting said arm with the frame and adjustably mounted, and a lifting-lever also connected with said arm.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
