SPECIFICATION forming part of Letters Patent No. 623,564, dated April 25, 1895 Application filed January 20, 1899. Serial No. 702,793. (No model.)

To all whom, it may concern:

Be it known that we, MARSHALL SATTLEY and AROHIBALD SATTLEY, of Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in. Cultivators, of which the following is a specification.

In a general sense this invention relates to convertible riding or walking cultivators, though some of the details are capable of application to non convertible cultivators as well. It is exemplified in the structure hereinafter described, and it is definedin the appended claims.

In the drawings forming part of this specification, Figure l is a plan of so much of a cultivator as is needed to illustrate our improvements with the parts placed in proper corelation for the operator to ride. Fig. 2 is a similar View. with the parts shifted to convert the device into a walking-cultivator. Fig. 3 is an elevation corresponding with the plan shown in Fig. 1. Fig. 4 is an elevation corresponding with the plan shown in Fig. 2. Fig.

2 5 5 is a front elevation of the front orhitch arch,

showing details of the means used to neutralize a part of the weight of the shovel-beams. Fig. 6 is an enlarged detail, inside elevation, of the weight neutralizing spring and adj uncts thereof. Fig. 7 is a detail in side elevation of the means employed to hold the seat at different heights, such elevation being taken on broken line x in Fig. 1. Fig. 8 is a plan illustrating a modified form of telescopic or extensible end contractible frame. Fig. 9 is a section on broken line a: in Fig. 8.

The structures delineated in the drawings and hereinafter particularly described are embodiments merely of our ideas. They show one way in which the invention may be put into practical use, but they are intended to be illustrative not restrictive. They give an instance of the conditions set forth in the claims, but it is obvious that such conditions may be exemplified by structures somewhat different in many ways from those shown. In this particular instance the invention is embodied in a cultivator made as follows, namely: An arched axle 1 is made in the form usual in straddle-row cultivators and is promeans of brackets l.

vided with carrying-

wheels

2 and 2. A pair of angle-bars 3 are laid crosswise of the axle, parallel one to the other, one on each side of the center of the axle and equidistant therefrom, and they are fastened to the axle by (Seen only in the elevations.) The forward ends of the angle-bars converge to the tongue 4,with which they connect, and their rear ends terminate to the rear of the axle. A cross-bar 5 connects the angle-bars together slightly to the rear of the bends thereof, and oblique braces 32 extend from the conjunction of the cross-bar with the angle-bars to the lower parts of the vertical extensions of the axle. The rear end of the tongue connects with the cross-bar 5, and a draft-bar 6 is connected with the tongue in the customary manner. These features constitute the carrying-frame or as much thereof as is needed to explain our invention, and on this frame the cultivating mechanism is mounted slidably, the means employed in this instance being as follows: A pair of slides 7 are mounted one on each of the angle-bars 3, and to the front ends of the slides is connected an arched bar or shaft 8.- This bar crosses the slides and extends laterally beyond the same on both sides. Then'ce it extends downward, as shown at S, and from the lower ends of the vertical extensions it turns inward, as shown at 8", and provides horizontal bearings for the beamcouplings. The arch-bar S is held in an approximately vertical position by braces 24, which extend upward and backward from the inner ends of horizontal extensions 8 and connect with the slides in the rear of archaxle 1. Between the ends of the slides and at the inner edges thereof are lugs 25, and the front ends of seat-bars 26 are connected pivotally with these lugs. Stud-brackets 28 extend from the converging parts 3 of the angle-bars 3, and bars 29 connect pivotally with the studs and also connect pivotally with the seat-bars at 30. The seat-bars extend parallel with the slides for some distance to the rear of the arch-axle and then converge to form a support for seat 27. Dhey are pro vided at 31 with swingable rest-blocks which are adapted to engage the axle and vary the height of the seat. The details of construction of the rest-blocks will hereinafter appear. Brackets are fastened to the rear ends of slides 7. They are provided with ratchet-racks 17 of are formation, and they furnish pivotal bearings for the lower ends of the lock-levers 16. Hooks 18 are pivoted onto the lock-levers, above the pivots thereof, and chains 20 extend from the hooks around bearings 19' on the forward arch'bar 8 and connect with the cultivator-beams 12, to the rear of the couplings thereof. The connection of the chains with the beams is made through short stubby springs, as 21, and rods, as 22, connecting the springs with eyes 23 on the beams. The beams have laterally-swin gable handles, as 13, and stirrups or foot-rests 14, as shown in Fig. 1, and they connect with the horizontal extensions 8 of arch-bar S by means of the coupling members 10 11 and sleeves f). The sleeves fit looselyon the extensions, thereby furnishing vertical play for the beams, and member 11 of the coupling swings horizontally on member 10 or 011 the pin thereof.

The sleeves 9 have arms 33 extending upward, and forward-extending heads 33 are formed on the upper ends of the arms. Extension-springs 31 are connected at their upper ends with the heads of the arms and at their lower ends with downward and forward extensions 21 of the brace-bars 2%. Links 35 connect the springs with the extension 24:, and a set of recesses at varying distances from the axes of sleeves 9 are formed in the extension to receive the link. This provides one means for regulating the tension of the springs and other means resides in the threaded bolt 36, which engages the upper end of the spring and extends through the head of arm and the nut 37 on such threaded bolt. (See Fig. 6.)

The rest-block 31 is shown in detail in Fig. 7,- and its leading characteristic is the set of bearing-surfaces 31 at different distances from its pivot. These bearing-surfaces are adapted to rest on the arched axle 1 and support the seat at different heights; but they can be swung entirely out of contact with the arch. In that case the seat-bars would rest directly 011 the arch and the seat would occupy its lowest position. Should this be'too low, the rest-blocks are turned to the position shown in Fig. 7, and the seat can beheld still higher by putting the other bearing-recesses into contact with the arch, as will readily be seen. So long as the seat is in riding position the beams will be held under the arched axle in position to be controlled by the feet of the operator, and the weight of arch-bar S and the adjuncts thereof will be in position to counterbalance his weight. Under these circumstances the spring 21. will act as a cushionspring to act against extreme depression of the beams, the chain and lever may be used to raise the shovels clear of the ground, and

the springs 34 will act as lift-sprin gs or weightneutralizers.

When it is desired to convert the device into a walking-cultivator, the seat-bars are swung forward on their pivots in lugs 25, raising the rear ends of bars 29 and forcing the slides rearward until the position shown in Figs. 2 and 4 is reached. Then the seat is out of the way, the arch-bar with the weight incident thereto is brought back close to the axle of the carrying-frame, and the beams are ex-' tended rearward to the proper positions to be used while the operator is Walking. Under these circumstances the chains may be left in their shown conditions and the cushionsprings be used to counteract extreme downward pressure on the handles, or they may be loosened to an extent to render them more or less inoperative, or they may be entirely disconnected. The lift-springs 34c will be used at all times, and they are particularly desirable on account of the even pressure they exert and the facility with which their tension may be regulated. They are put under tension to the desired extent by means of the bolts and nuts in the heads of the arms, and they are set nearer to or farther from the axis of the pivots of the arms according to the extension it is desired to give them as the beams are raised and lowered. They are always under tension, the rock of the arms does not vary the tension excessively, the leverage increases as the tension decreases, and there is no perceptible variation in the action of the springs on the beams from the beginning to the end of a lift. The adjustment of the belts in the heads varies the tension of the spring or the pull that it exerts, while the adjustment of the links in extensions 24" varies the extension of the spring or the distance that it stretches. One adjustment is complementary of the other and neither produces precisely the same effect as the other.

The seat-bars act as levers to extend or contract the frames, and they are well adapted for that purpose for the reason that the swing that converts the device into a walking-cultivator carries the seat out of the way, while the reverse movement brings it back again; but it is obvious that a great part of the advantages incident to the extensible frame can be obtained by using shifting-levers having no connection with the seat or even by omitting levers altogether.

In Figs. 8 and 9 a suggestion is given of an extensible frame in which the axle is connected with the slide, and the arched draftbar is connected with the an gle-bars that form the hounds of the tongue. In that instance the frame is shown in plan in Fig. 8, while Fig. 9 is a section through a modified slide. The

angle-bar 3 bears against an angular surface formed in the bearing-block 7", fixed on the axle, and is held in place by a strap 7 which is fastened to the block.

The entire cultivating mechanism, includin g the lifting-lever and the accessories thereof, are carried on the slides, and so there is no disa'rrangement of parts when the device is converted from a walking-cultivator to a riding-cultivator, and the reverse.

The lift-spring is applicable to all straddlerow cultivators, and the extension 249 of the brace-bar 24 is merely typical of a relatively immovable part of the frame adjacent to the rock-arm.

Having thus described some of the forms in which our invention may beembodied, we now proceed to concisely point out the features that we claim as new and desire to protect by Letters Patent, namely 1. In a cultivator, the combination of a draft-frame, having carrying-wheels, a slide mounted to move lengthwise of the frame, beams. connected with the slide and beamraising mechanism also connected with the slide.

2. In a cultivator; the combination of a draft-frame, an arched axle for the draftframe having carrying-wheels, a slide on the frame adapted to move lengthwise thereof, an arched bar connected with the forward end of the slide, beams connected with the arched bar, levers on the rear end of the slide, and chains or the like extending from the levers forward, around bearings on the arch-bar and downward to the beams.

3. In a cultivator, the combination of a frame consisting in part of two parallel bars lengthwise of the cultivator,an axle connected with carrying-wheels, a slide on each of the bars, a transverse arch-bar connected with the front ends of the slides, cultivator-beams connected with the arch-bar, levers on the rear ends of the slides, chains, or the like extending from the levers around bearings on the slides and connecting with the beams, and braces extending from the lower parts of the arch-bar and connecting-with the slides in the rear of the axle.

4. In a cultivator the combination of a draft frame having carrying-wheels, a slide mounted to move lengthwise on the draft-frame, cultivator-beams connected with the slide and a lever to shift the slide on the draft-frame.

5. In a cultivator, the combination with carrying-wheels and cultivator-beams longitudinally shiftable with relation to the wheels, of horizontally-extending lever-bars to shift the wheels and beams with relation to each other, and a seat on the extended ends of the levers.

6. In a cultivator the combination of a Wheel-supported frame, a slide lengthwise thereon, cultivator-beams connected with the slide, seat-bars pivotally connected with the slide, and links connecting the seat-bars, with the wheel-supported frame.

7. In a cultivator, the combination with the frame'and the axle thereof, of seat-bars pivoted to the frame in front of the axle, and swingable rest-blocks pivoted on the bars and having bearing-recesses at different distances from their pivots, which recesses are adapted to engage the axle.

S. In a cultivator, the combination with the horizontal sleeve of the beam-coupling, of a vertical arm rigid with the sleeve, and an extensible spring connected at one end with the extended end of the arm and at the other end with a relatively immovable part of the cultivator adjacent to the axis of the sleeve.

9. In a cultivator, the combination with the horizontal sleeve of the beam-coupling, of a vertical arm rigid with the sleeve, an extensible spring connecting with the extended end of the arm by means of a bolt adjustable lengthwise of the spring, and a set of relatively immovable bearings for the opposite end of the spring near to and at difierent distances from the axis of the sleeve.

In testimony whereof we sign our names in the presence of two subscribing witnesses.
