AGRICULTURAL IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 651,092, dated June 5, 1900 I Application filed July 13, 18:97. Serial No. 644,401. (No model.)

citizen of the United States, and a resident of Moorestown, State of New Jersey, have invented certain new and useful Improvements in Agricultural Implements, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain improvements in agricultural implements and has for one object to provide an improved form of horse-machine which will enable the operator to accomplish almost every kind of work possible in the cultivation of crops.

A further object of my invention is to provide for the regulation of the pressure exerted to force the cultivator-teeth into the ground and adjust the tension in accordance with the character of the soil, and to govern and adjust the position of the teeth by means of a single operating-lever upon each side of the implement.

A still further object of my invention is to so construct the teeth-holding frames that they will be perfectly rigid and may be adjusted both vertically and laterally for different classes of work.

A still further object of myinvention is to provide for the ready adjustment of the teeth on the frames so that furrows may be made at any required distances from each other.

A still further object of my invention is to improve the construction of the guiding mechanism for the supporting-wheels, the wheelpivots being arranged close to the wheels, so that great freedom and rapidity of movement may be attained.

Further objects of my invention are to provide for a low draft of the tooth-holding frame, to improve the construction of the frame and provide for its ready adjustment, and generally to improve, simplify, and cheapen the construction of the machine, as more fully set forth hereinafter. v

In the accompanying drawings, Figure 1 is an elevation of an agricultural implement constructed in accordance with my invention. Fig. 2 is a sectional plan view of the same on the line 2 2, Fig; 1. Fig. 3 is a rear elevation of the machine, partly in section, on the line 3 3, Fig. 1. Fig. 4 is a sectional elevation, on

an enlarged scale, of a portion of the mechanism illustrated in Fig. 3 and showing more clearlythe construction of the wheel-hub and its pivotal support. Fig. 5 is a sectional plan View on the line 5 5, Fig. 4. Fig. 6 is a detail view of the forward end of one of the tooth-carrying frames. Fig. 7 is a transverse sectional elevation on the line 7 7, Fig. 6. Figs. 8, '9, and 10 are detailed views in the nature of diagrams illustrating some of the positions to which the tension-spring and the levers of the teeth-carrying frame maybe adjusted. Fig. 11 is a detail perspective view of the adjustable support for the forward end of the tension-spring. Fig. 12 is a sectional plan view, on an enlarged scale, on the line 12 12, Fig. 1. Fig. 13 is a detached perspective view of one of the clamps forconnecting the arch ed wheel-carryin g frame to the yokes. Fig. 14 is a detached perspective view of the pi votblock by which the steering mechanism is carried. Fig. 15 is a sectional elevation of one of the cultivator-teeth and its carryingclamp. Fig. 16 is a transverse sectional elevation of the same on theline 16 16, Fig. 15. Fig. 17 is a detached perspective view of one of the teeth-carrying clamps. Fig. 18 is an elevation illustrating one of the catches for the operating-levers, and Fig. 19 is a sectional elevation of the same on theline 19 19, Fig. 18.

Referring to the drawings, A represents the supporting and guiding wheels, carried by an arched frame B, which latter is attached to the rear end of the longitudinal bars 0 of the upper frame. At a point some distance forward of the frame 13 is a yoke-like bar D, secured at its upper end to the longitudinal bars 0, which it serves to space and brace. At a point near the lower end of this bar are secured bracing-bars D, extending from thence to a transverse bar D which connects the opposite side bars of the frame and acts partly as a support for the main vsingletree D The lower ends of the bar D are bent at right angles and project outwardly in the form of pivot-bars (1, their extreme outer ends being braced by bars d, connected at one end to the frame B and at their opposite ends to the pivot-bars d. On the pivotbar dis pivoted a Frame E of the construction more clearly illustrated in Fig. 6 and comprising opposite side bars e, connected at intervals by integral cross-bars e e e and.

having at' their rear ends openings 6 for the passage of the pivot-bolt of the tooth-carry ing frame referred to hereinafter. These side bars e are also provided with segmental slots (2 through which may pass an adjusting-bolt g carried by the extreme forward ends of the gang-frames and permitting vertical adjustment of the latter to a considerable extent, the bolt 9 being tightened when the desired adjustment has been effected and holding the gang-frames securely in place.

In the forward end of the cross-bar e at points between the side bars 6 are formed openings or recesses f, through which may pass a securing-boltf, carried by a clamp F, which surrounds the pivot-bar (Z, the clamp and the frame E being adjustable laterally on the pivot-bolt and being locked in any desired position by the tightening of the boltf. Any independent lateral movement of the frame E is prevented by the contact of the clamp on one side with the side bar 6 and on its opposite side by a finger f, formed integral with the bar 6, from which it projects and partly embraces the pivot-bolt (Z. The lateral adjustment which may be eifected by the construction described permits of the use of the machine between furrows of any width, and the vertical adjustment of the gang-frames permits of a considerable change in the angle and position of the cultivatorteeth, plows, or other tools which are carried by the gang-frame.

To each frame E is secured'a gang-frame G, formed of two flat strips 9 g of wroughtsteel, which at their rear ends are in close contactwith each other and at their forward ends are so bent as to form a rigid structure, the angles of bending being so arranged that any lateral strain will be taken up and the rigidity of the frame insured. The gangframe is pivoted to the frame E by a bolt g and at its forward end carries a bolt 1 which passes through the slots 6 of the pivot-frame E. As the bars 9 g are on opposite sides of the frame E and are secured and clamped at two points to said frame, the gang-frame will be rigidly held in place.

The singletree D is pivoted centrally to the connecting-bar D and extends for some distance beyond the sides of the longitudinal bars 0 and is provided near its opposite ends with eyebolts h, to which are hung draft-bars H, provided near their lower ends with a series of openings h, to any one of which may be secured the bolt 7&2 of the doubletrees 11, while to the extreme lower end of the bar or to any one of the openings 7b is secured a link h connected at its opposite end to a link It, extending from the pivot-bolt (Z, the point of connect-ion between the link and the pivotbolt being preferably between the finger j and one of the side bars 6 of the frame E, so that the draft will be exerted directly upon the teeth-carrying frame. It will be noted that the draft connection is extremely low and the tendency of the pulling force will be exerted in a direct line and will tend to depress the teeth rather than elevate them, as would be the case if the draft connection were above the level of the tooth-carrying franie.

On the outer sides of the bars 0 are secured plates I, from which project stud-shafts 'i,which maybe formedintegral with the plates. On these studs are pivoted levers I, each lever having two arms 2" 2' curved at t at the juncture of the two arms, and the lower end of the arm 2 being curved to form a stop for limiting the range of movement of the tension-spring. The rear end of the arm 1' is connected by links j to the bar 9 of the teethcarrying frame, so that any movements of the lever are immediately transmitted to the toolearrying frame and the desired vertical adjustment of the latter may be thus effected.

To each end of the cross-bar D is secured an arm 76, provided with an openingk, through which passes the threaded stem of an eye bolt H, and such threaded stem is provided with an adjustingnut k which may be turned to adjust the tension of a spring K, one end of which is secured to the eyebolt The opposite end of the spring K is secured to a plate L, having its rear end bent in yoke form, as shown in Fig. 12, in such manner as to partly embrace the lever I and to form a support for the shaft Z of a roller Z, which is adapted to travel on a trackway formed on the rear face of the arm 2" of the lever I.

On each of the bars 0 is secured a small frame M, having a curved upper face in which are formed a series of holding-notches m, adapted to coaet with a pair of locking-bolts m m carried by a lever N, pivoted to the frame M, and to hold said lever in any position to which it may be adjusted. The locking-bolts m m are adapted to guides m carried by the lever N, and each has a separate spring on, by which it is forced into contact with the frame M or its notches in, the arran gement being such that one or other of the bolts will always be in engagement with one of the holding-notches and its fellow will be in contact with the surface of the frame, and thus gain the same effect of numberot' possible lockings as though the frame were twice as large, and, in combination with a single locking-bolt,had twice the nu mberof notches. The upper end of each bolt is recessed for the reception of a rod or wire on, by which either or both may be raised from engagementwith the notches in. Secured to or formed integral with the lever N is an infill Qt, having its outer end connected by linksjt' to the plate L, preferably by the pivot-shaft Z of the roller Z.

The operation of this portion of the mechanism is as follows: When the parts are in positions illustrated in Figs. 1 and 8,with the roller Z in contact with the lever I at a point above its pivot i, the tendency of the spring is to elevate the arm '6 and, through the links j, reduce the weight of the teeth-carrying ICO frame on the ground, and consequently to reduce the depth of work till exactly suited to the ground or to the wishes of the operator, and if the lever N be drawn back until the roller Z is in contact with the curved portion of the lever I the teeth will be raised clear of the ground and permit the free travel of the machine to and from the field of operation. When the lever N is moved in such manner as to bring the roller Z to a point directly opposite the pivot 11 the tension-spring will exert no force whateverupon the lever I and the cultivator-teeth will be held in the ground merely by their own weight, added,of course, to the weight of the carrying-frame.

This is desirable for work in medium soil or where the penetration of the teeth is comparatively easy. In heavy soil or where deep furrows are desired the lever N is so adjusted as to move the roller Z to the position illustrated in Fig. 10, in which case the tension of the spring will exert a downward pressure on the teeth-carrying frame through the arm 2' and the linksj and will keep the teeth in constant contact with the ground, at the same time permitting the raising of the teeth when they strike a rock or other obstruction,and so avoid breaking or straining of any of the parts. If a rock or other obstruction be met with and the teeth raised from the ground,the tension-springs will immediately force the teeth into the ground. As soon as the obstruction is passed the work is instantly resumed.

The range of movement of the lever N is limited in one direction by the stop 2' with which the roller Z comes in contact,and in the opposite direction by a stop i ,projecting from one or both sides of the arm t and arranged to come into contact with the links a when the lever N is drawn fully backward.

The axles of the supporting-wheelsand the top bars 0 are connected by an arched frame B, formed of two flat strips 0 of wrought-iron separated by a number of spacing-blocks,'

which also serve as a means for connecting the frame to the upper bar 0 and to the axlepivot. In order to gain the greatest strength, the bars 0 are curved or arched in their width and at their lower ends and sides are connected by blocks 0 O, in which are swiveled vertical bars P, ,the lower ends of which are bent outwardly at a right angle to form axles for the reception of the hubs p of the supporting and guiding wheels A. At that point on each of the pivot-bars Where the binding takes place the pivot is surrounded by a twopart box q q, the upper face of which supports the weight of the machine and forms a bearing on which the lower face of the block 0 may turn. In order to place the pivot P close to the wheel-hubwithout sacrificing the bearing-surface of the hub upon its support, the meeting faces of the hub-p and the portion q of the clamp are faced off and accurately fitted to each other in such manner as to form a vertical bearingcapable of sustaining considerable side thrust and acting to replace the horizontal hearing, which would be formed normally by the inwardly-projecting portion of the hub. The outer portion of the hub is somewhat elongated and is held in place by a collar p fastened in position by a pin 19, which extends through the axle' p. The blocks 0 O are somewhat wider than the bars 0 and are recessed, as shown at 0, Fig. 5, for the reception of such bars.

The upper portions of the frame are connected to the horizontal bars 0 by blocks R of the character more clearly shown in Fig. 13, each block being provided with recesses I, which serve to space and hold the bars of the frame in proper position.

Secured centrally between the bars of the frame is a box or block R of the character more clearly shown in Fig. let. This block extends to some distance below the bars of the frame and carries two parallel bars S, one of which passes through an opening 1', formed in the lower portion of the block R, and the lower bar extending under theblock B. These two bars are pivoted at r to the block and at their outer ends are pivotally connected to steering-bars S, bolted or otherwise secured to the pivot-bars and having integral inwardly extending foot pieces 8, against which the operator rests his feet, and by pushing on one or the other the pivotbolts will be turned simultaneously, owing to the connection between the bars S and-the centrally-pivoted bars S. This construction permits of the rapid turning of the machine and enables it to be easily guided in following between furrows. The lower portion of the block R has an arm R provided with a segmental slot r through which passes a pin r riveted or otherwise secured to the bars F, the end walls of the slot forming stops which limit the movement of the bars S. arm R is a slot or opening 1 through which and through similar openings in the bars S may be passed a pin to lock the bars S in a central or normal position when the machine is to travel for any distance in a straight line.

To the upper portion of the bar D are connected the opposite ends of a U-shaped bar T, the rear portion of which extends for some distance back of the frame B and rests upon the upper portion thereof. The barT carries a drivers seat '6, clamped in position by a bolt t, passing through a transverse bar t which extends under the two sides of the bar T and firmly holds the seat in position. ing the securing-nut of the bolt t the seat and the clamping-bar t may be moved backward and forward 011 the bar T and clamped in any desired position.

Referring to Figs. 15, 16, and 17, U represents a cultivator-tooth or other tool, centrally secured by a bolt a to a slotted arm a, pivoted at n to a standard V. The upper portion of the bar to is provided with openin gs 1t ,throu gh any one of which and through a similar opening in the standard may pass a securing-pin n so as to permit of the ad In this- By loosenjustment of the angle of the teeth U. The upper portion of the standard V is in the form of an elongated tube and is adapted to pass through openings w in a clamp W, and the length of the standard is suliicient to permit of the vertical adjustment to a considerable extent, so that the distance of the teeth from the supporting-frame may be varied as required. The clamp W has lateral openings w of a width sufficient to receive the bars 9 g of the supporting-frame and is also provided with a set-screw 10 which may be turned to force the bars of the supportingframe into intimate contact with the standard and the latter into contact with the clamp, firmly locking the tooth into position. This construction permits not only of the vertical adjustment of the teeth, but also of their circumferential adjustment, and permits the locking of the teeth at any point on the sup porting-frame, so that they may be set for furrowing at any required distances.

In Fig. 2 it will be noted that the bars g, at a point close to their connections with the frames E, are provided with tooth-holding clamps, the securing-screw 10 being of sufficient length to permit the clamping of the tooth to a single bar in lieu of the double bars, which form the rear portion of the supporting-clamp.

Normally the implement carries eight narrow teeth, four on each of the supportingframes; but for fallow earth a ninth tooth,

carried by a frame y, may be employed. The 1 frame 3 is of V shape and is inclined at an angle corresponding to the angle of the forward ends of the bars g and is locked in position by passing its ends through the openings 10 of the clamp, after which the set-screw is turned to clamp the bars g, the frame 'y, and the teeth in position.
