IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 185,932, dated January 2, 1877; application led October 5, 1876.

To all Iwhom it may concern:

Be it known that I, JAMEs HERVA JONES, of Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Oultivators, of which the following is a specification:

My improvements chieiiy relate to a cultivator of the class known as straddle-row machines, which are provided with split tongues,77 or those formed of two pieces converging from the axle forward to a point at which they join.

The objects of my invention are to perfect and simplify the devices by which the shovelbeams or drag bars are connected with the main frame in such manner as to allow them free play, within certain limits, both horizontally and vertically, without possibility' of their twisting or wabbling; to so connect the beams with their liftinglevers that they may be moved sidewise, substantially on a level or in the same horizontal plane throughout their movement, whether the shovels are at work or elevated; to render various working parts of the machine reversible and in tercbangeable; and generally to increase the efciency of the machine.

The subject matter claimed will hereinafter speciically be designated.

The accompanying drawings illustrate all my improvements as embodied in a single machine. Obviously, however, some of the improvements may be used without the others, and in machines differing somewhat in construction and operation from that therein shown and hereinafter described.

Figure 1 represents a plan or top view of my improved cultivator, with a portion ofthe outer end of the tongue or draft frame broken away; Fig. 2, a side elevation of the same, with one of the supporting wheels removed; Fig. 3, a transverse vertical section therethrough, on the line 1 l of Fig. l, looking from the front. Fig. 4 is a plan view of a portion of the front end of the tongue removed from Fig. l 5 Fig. 5, a side elevation of a portion of the section of tongue broken away from Fig. 2. Fig. 6 is an enlarged View, in elevation, of a portion of the inside of one oftheshovel-beams,showingthemannerofconnecting therewith one of the holders by which the arm or shank of one ofthe shieldsis secured in position; Fig. 7, a vertical section on the line 2 2 of Fig. 6, representing a front view of the connections between the shovel-beam and shield-shank. Fig. 8 is a side view, on an enlarged scale, of the front end of one of the shovel-beams or drag bars, showing its connection with the pendant or down-hanger from the main frame, the pendant being in section in the plane of the line 3 3 of Fig. 9; Fig. 9, a view of the same parts, partly in plan, the pendant being in section on the line 44 of Fig. 8. Fig. l() is a view, in perspective, ofthe reversible socket for the tongue. Fig. l1 is a vertical section on the line 5 5 of Fig. 1, showing the devices for securing the evener and preventing wabbling, and Fig. l2 a vertical section on the line 6 6 of Fig. 1, showing a front elevation of one of the connections between the seat-pieces and tongue-pieces.

The supporting-wheels A A are secured upon the opposite ends of an elevated cranked or bent axle, A', as usual. The split tongue or draftframe is formed of longitudinal pieces B B, secured at their rear ends to the axle, and converging forward therefrom to their front ends, where they join and are connected together by a metallic double socket-piece or webbed casting, a, which is provided at its front end with an angular projection or short inclined arm, a', having a hole for the attachment of an eyebolt, b, to connect with the ordinary neck-yoke of the team. The sockets on either side of the central portion or web of this casting a, formed between the upper and lower flanges, receive the ends of the tongue-pieces, which are secured in place by means of a bolt and nut or screw, b', passing through the tongue-pieces and web ot' the socket-piece. By removing the fasteningscrew, detaching, removing, and refastening the webbed casting or socket-piece, it will be seen that the neck-yoke eyebolt may be raised or lowered to suit diterent teams. A brace, B', between the side pieces` of the tongue, near its front, prevents them from being injured or sprung out of place by inward pres-sure of the draft animals. A cross-piece, O, parallel with the axle, is secured beneath the tongue to the opposite side pieces thereof, about in line with the front ofthe wheels. The evener C is pivoted upon a short arm or bar, c, secured to and projecting forward from the cross-beam G, above mentioned, of the main frame. It is provided at each end with two draft-hooks, d d1, for a wellknown purpose. The pivot pin or bolt d of theevener is fitted above the evener with an elongated broad-based enveloping sleeve or tubular casting, D. The bottom flange D1 of this sleeve bears upon the top of the evener, while vertical movement is prevented by means of the strap-iron or retainingbrace D2, through which the pivot d2 passes. and against which the top of the sleeve bears. The pivot may either be headed down upon the strap to secure it against vertical movement, or provided with a screw and nut or other well-known retaining devices, which will effectually prevent endwise movement of the long sleeve D.

It will be seen that all tendency of the evener to twist or rock vertically is eectually counteracted by means of the broad bearing of the base of the sleeve D, and that, owing tothe height of this sleeve and the leverage attained thereby, there is but little strain on the strap-iron, even when the draft is applied to the lower hooks of the evener.

Secured beneath the frame cross-piece C, near the ends thereof, are two pendants or down-hangers, E E, slotted at their lower ends. The upper ends of these pendants are provided with anges, to give them a broad bearing against the cross-beam, and admit ot' their being strongly securedin place by screws or otherwise. To give additional strength to the pendants, they are braced by means of diagonal bars E1 E1, which are connected at their front ends to the pendants, about midway of their length, and secured at their rear ends to the cranks of the axle. At either side, and projecting inward from the opposite walls of the slots in the lower ends of the pendants, are V-shaped ribs or centrallyraised projections e e. (See Fig. 9.) The opposite sides or branches ofthe pendants formed by the slots are connected at their lower ends by round crosspieces or pins e1. Each shovelbeam or drag-bar F is connected at its front end to its down-hanger E, so as to swing sidewise and rock vertically, and yet be incapable of twisting or Wabbling to any appreciable extent, such as practically to interfere with the perfect work of the shovels by inclining or tilting them. A hooked plate, F/ one for each 'beam-may besecured in place by itting its rearwardly and downwardly projecting portion in a slot in the forward end of the beam, and passing a pin or bolt through the beam and plate. The hook-plate for each beam is made of a thickness but slightly less than the opening through the pendants, or the distance between the opposite ribs of the slot walls. and is also of a width or height suciently great to aiord a bearing against the sides of the slot long enough to prevent any injurious wabbling or twisting of the plate therein. The hook f, at the under front edge of the plate, tits on the cross-piece e' of the pendant; and the upper edge f of the plate,

at and near its front end, is curved, and works during the rocking of the beam close to the central solid portion of the pendant or top wall of the slot, to preventf accidental disengagement of the hook.

In securing the hook in` place, and in removing' it from the slotteddown-hanger, it is necessary, it will be seen, tordepress the rear end of the shovel-beam to a much greater extent than is ever reached by it while the machine is in operation.

But two pieces are required to make each connection of a beam with. the framethe vertically-slotted down-hanger and' the hooked plate-while leaving the beam free to be given all movements required while at work. Too great sidewise movement is prevented by the bearing of the broad-faced plates against the inclined sides of the central ribs or projections of the slots at the extremity of the movement to which it is desirable to'limit'the beams.

From the construction of the down-hangers, it will be noticed that they` are interchange able, and that no precautions are needed in securing them in place upon the frame, for so long as the slot is at right angles to the crossbeam either side can be placeding'ront.V

The driver is enabled to lift and lower the shovel-beams by devices which allow the beams at all times, whether' raised or lowered, to be swung sidewise substantially on a level or in the same horizontalplane.

To admit of the horizontal swing of the beams in machines like thatherein represented, in which the drivers` seat is mounted in rear of the axle, and thelevers for controlling the beams located some `distance in rear of the hinged connection between the front ends of the beams and the main frame, so as to bring the levers within easy reach of the driver in his seat, it becomes necessary to connect the upper ends of the' lifting-connections ot' the beams with the levers by a supportin advance of them and intermediate ot them and said connections, so as to locate the points at which the connections are jointed at their upper ends substantially in thesame vertical plane as that in which the joints between the front ends of the beams and frame are located, and thus enable the connections and beams to swing around a common, or substantially common, center. Each beam, in this instance, is connected by links Gr, dr other suitable ilexible connection, with a support, consisting of an endwise-moving rod or thrust-bar, Gl, operated by a lever, G2. The lower end of the link-connection Gr, it will be seen, is secured to the beam, seas to enable it to be lifted easily, at some distance from `its forward end; and from its lower end the connection extends upward and forwardtoffthe thrust-bar G1, where it is jointed at a'point over, and but slightly in rear of, a line. drawn vertically and nuts through the joint between the forward end of the beam and the down-hanger.

By this manner of connecting the beam and lifting-lever, it will be seen that when swinging sidewise the two centers upon which the beam swings are nearly in the same vertical plane, and that for all practical purposes the beam swings sidewise in a horizontal plane, or without appreciably varying the depth at which the shovels carried thereby are working. The forward end of the thrust-bar works in a suitable guide, g, on the cross-beam C, while its-rear end is jointed to one end of a short arm or crank, g', the opposite end of which is secured to the rocking hand-lever G2. (Shown as secured by a bracket, G3, to the outside of the tongue-piece, by the side of which the thrust-bar is located.) A suitable segmental detent and engaging devices enable the operator to hold the beam at any eleva` tion desired. The lifting devices for both beams and the various parts connected therewith are alike, and therefore a description of .such parts, as applied to the remaining beam, 1s unnecessary.

To cause the two-shovel beams to move sidewise together they areA connected by means of a yoke, H, the elevated central portion of which is parallel with the axle and extends along in front thereof, while its downwardlyprojecting ends H1 pass through slots in metallic plates lo, (shown as held in place by the eyebolts 101,) bywhich the inclined liftinglin ks G are secured to the beams. Thus while the beams may be raised and lowered independently of each other, they are compelled to move sidewise together. The yoke is supported and prevented from moving up and down by rods H2 H2, curved to pass around the thrustbars, secured at their opposite ends, respectively, to hooks h2 on the fronts of the brackets G3, and headed pins h3 on the yoke ends. These pivot-pins h3, it will be seen, are sufficiently long to accommodate the slight oscillating movements of the yoke caused by raising and lowering the beams. By this manner of constructing the rods 2 and loeating them, the same brackets Gr3 which support the lifting-levers and thrust-bars are made to sustain the yoke, while allowing-free endwise movement of the thrust-bars along the outsides of the tongue-pieces and inside the rods. The location ot' the supporting horns or hooks h2 leaves unobstructed the working of the levers and their retaining devices, which engage with the detents of the brackets.

The drivers seat I is mounted some distance behind the axle, upon the rear ends of two wooden spring pieces, I l. These pieces converge from their front ends to the seat, and are secured at their front ends inside the tongue-pieces by means of long screw-bolts The bolts project upward from metal brackets J J, which `are adjustable back and forth upon the tongue-pieces by means of the anges jj, which embrace the outside of the tongue-pieces, and screws or bolts passing' through said flanges and into or through the tonguepieces. The bolts i z', by which the front ends of the seat-frame are secured to the adjustable brackets, are made long enough to admit of the vertical adjustment of the seat. By screwing the nuts up or down upon these bolts it will be seen that the rear end of the seat-frame will be depressed or raised, the frame rocking upon the axle of the machine as a fulcrum. By this construction the seat can be moved forward and at the same time lowered to enable the driver, it short, to reach the foot-rests K K upon the shovel-beams, and thus enable him to control the sidewise movement of the beams, while for a taller person the seat may be moved farther back and raised by adjusting the brackets and manipulating the screw-bolts. By this adjustment not only is the driver enabled to reach the foot-rests, but the weight of the forward part of the machine and downward pressure thereon can becounterbalanced, and the driver be located in a position best suited to enable him to operate the lifting levers.

The shovel-standards L are secured to the rear ends of the shovel-beams in such manner as to admit of their ready adjustment to different inclinations thereto, and so as to allow them to swing back, when encountering unyielding obstructions, to avoid injury to the machine. Each beam in this instance carries two shovels, L1 L2, one secured to its inside and the other to its outside. The standards are all connected with the beams in like manner; hence a description of the attachment of one suffices for all. Each standard is directly secured by means of an eyebolt, l, in a groove in the outer face of a plate, l. The eyebolt passes through this plate and is drawn tight by a nut, l2, on the threaded end of the bolt, which nut bears against one face ot' a bracket, or, as I prefer to term it, a slip-casting, M, through which the threaded end of the bolt passes. The adjusting surfaces or contiguous inner faces of the slip-casting M and plate l1 are of circular outline and serrated or indented, as shown. Thus, when the bolt is drawn tight by its nut, the standard, plate, and bracket or slip-casting are locked firmly together. By loosening the nut the serrated faces may be turned upon each other to adjust the inclination of the standard. The slip-casting M is formed with two upwardlyprojecting inclined arms, m m, slotted as shown, to receive the headed bolts m1 m1, which pass through the beam and are drawn tight by the nuts on their opposite threaded ends. The serrated portion of the slip-casting or bracket M, it will be seen, projects downward below the beam so that the eyebolt l passes through it beneath and clear of the beam, thus admitting of the adjustment of the standard without disturbing the bracket. Moreover, by thus lowering the serrated face of the bracket the shovel-beam may be swung higher than usual, and thedrivers seat correspondingly raised. I am also enabled to use a shorter shovel-standard than could be employed were it secured higher on the bracket or directly to the side of the beam; smaller and consequently cheaper iron may be used to form the standard than is needed for a long one; and the short standard may be adjusted or slanted forward much nearer to a horizontal position than a long standard could be, Without throwing the shovel and foot of the standard forward to an objectionable extent. The range of adjustment of the standard is therefore increased by shortening it and lowering its point of attachment to the bracket. The slotted arms of the pendent slip-castin g, it will be observed, are of equal length and radiate from a common center, the centers of the slots therein being equal distances from the eyebolt l, by which the shovel-standard is secured in place. Thus it will be seen that these slip-castings are all alike, and that they are interchangeable, as the same one may be used either inside or outside the beam. When an obstacle is encountered the. forward arm of the casting slips from its retaining-bolt, being held by friction only, and the casting swings back on the rear arm. As soon as the obstacle is passed the casting is again adjusted as before.

Shields or guards N N for protecting the plants from the earth, stones, Snc., turned up bythe shovels, are located, as usual, inside the inner shovels. These shields are elliptical or oval in form, as shown, and are removably connected to the shovehbeams. They are both reversible and interchangeable, and are secured in place so as to be free to rock vertically within certain limits and accommodate themselves to inequalities in the surfaces over which they move. The shields are exactly alike, and the manner of attaching both the same. Their bent shanks a n extend forward and sidewise, and each is provided with a hook or loop, a', at its end, to embrace a pendent bracket or holder, 0, one for each beam. The holders are each secured to the inside of its beam by means of a screw-bolt and nut or screw, 0', by loosening and tightening which the holders may be inclined by swinging to adjust their elevation, and secured in the desired position. The hooks n' clasp the pendants O 0, and each of the shanks n rests at its forward end, when the shields are depressed to their lowest limits, upon the rear side of the double incline or centrally-projecting ^shaped upper surface p of the inwardly-projecting lower end P of the pendent holder. A pivot-pin, p', serves to secure the shank to the holder, and allow it to rock. The pivots p should be secured in place so as readily to be detached when it is desired to remove or reverse the shields.

lt will be seen that both the upper and lower edges of the shield are alike, and that either edge can be used as a cutting or working edge. When the edge of either or both shields becomes worn or battered, theyare each detached,

turned, and secured in place upon the opposite beam. The holders are likewise interchangeable, and, by means of their double inclines, prevent the shields from entering the `soil too far, alike when applied to either beam.

The operation of myiimproved machine will readily be understood from'the foregoing description.

Various modifications thereof may be adopted without departing from the spirit of my invention-such, for instance, asforming the cross-beam C of the main frame with slots or forward bends at the points where the thrust-bars cross it, and attaching the liftingconnections farther yforward to these bars, `so that when the beams c are lowered and the shovels at work (the time when it is imporj tant that the beams should swing sidewise horizontally instead of .describing a vertical curve) the points of connection between the links G and thrust-bars'will be brought ldirectly `over the joints between the frontiends of the beams and the down-hangers. A like result would `be producedi by declining the downhangers backward; but the construction shown answers well impractice, the very slight difference in the depth .at which the shovels work, caused by swingingfthe beams to their extreme limit, being immaterial, the -depth at which they work bein gsubstantially the same throughout their swing.`

It is also obvious that the shields may be made of a semi-elliptical,form-that is, with their rear ends of adifferent form from that shown, and that a single incline on the holderprojections would answer for the attachment of the shield-shanks,land admit equally `well of the interchangingi of `the shields.

I claim as my 'inventionl. The combinationofthe evener, with double draft-hooks, the pivot-pin connecting it to the machine, the elongated broad-based tubular sleeve enveloping the pivot-pin and bearing upon theupper surface of the evener, and the strap-iron or brace, these membersbeing constructed and operating as set forth, for thefpurpose specified.
