SPECIFICATION forming part of Letters Patent No. 640,325, dated January 2, 1900.

Application filed October 23, 1399. Serial No. 734,439- (No model.)

To (LZZ whont it may concern.-

Be it known that we, llL-iRsHxLL SATTLEY and ARGHIIBALD SATTLEY, of the city of Springfield, county of Sangamon, and State of Illinois, have invented certain new and use ful Improvementsin Cultivators, of which the following is a specification.

This invention relates to cultivators that are convertible from ridingcultivators to E0 walking-cultivators and the reverse. It is in the nature of an improvement on the convertible cultivator described by us in Letters Patent of the United States No. 623,564. It is exemplified in the structure hereinafter described, and it is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a side elevation of so much of a cultivator as is needed to explain our invention, showing the parts in position to form a riding-cultivator. Fig. 2 is a simi- 'lar view representing the parts in transposition from a riding-cultivator to a walkingcultivator. Fig. is a plan with the springs on one side omitted to show details that the springs would obscure.

Supporting-wheels 1 are journaled on an arched axle 2, and the axle is fixedly connected with the side bars 4 of the cultivatorframe by clainp-brackets The bars of the frame converge at their forward ends to engage the tongue 5, and a cross-bar 6 is attached to the converging parts of the bars and connected from its ends to the spindles of the arched axle by means of rods 7. A cross-shaft 8 is secured to slides on the frame in front of the axle, its ends extend sidewise beyond the bars =1- of the frame, and on such extensions are journaled sleeves 9, which are preferably ribbed longitudinally on their exterior surfaces, as shown at 9 in Fig. 3. Vertical sleeves 10 are mounted adjustably on sleeves 9, and upturned terminations ll of cultivatonbeams 12 are journaled in the vertical sleeves. A pair of slides 13 are mounted one on each side bar a, and each slide has a downward extension l t in the rear of the axle. The cross-shaft 8 is connected with the front ends of the slides. The extensions let are fastened to or formed on the rear ends of the slides, and arms 15, having notches in their ends, extend forward from the front ends of the slides. Arms 20 are mounted on sleeves 9, so as to partake of the rocking motion thereof. They extend obliquely upward and backward from the sleeves on which they are mounted, and they have upturned bends 21 at their swinging ends. Springs 17 are connected with the relatively stationary arms 15 by means of links 16, and they are also connected at their opposite ends with extensions 21 of rock-arms 20 by means of threaded bolts 18 and set-nuts 19. The arms 20 have bellcrank extensions 22, downward extended,and springs 2a are connected with such extensions of the rock-arms and with the extensions on the rear ends of the slides. Links 23 connect the springs 2% with the extensions of the rockarm, and chains 25 connect with the opposite ends of the springs and with threaded bolts 26, which pass through extensions 14. Lugs 27 connect with the slides and extend rear ward from the cross-shaft. Seat-bars 31 extend under the axle when the cultivator is used as a riding-cultivator and are pivotally connected with the axle by means of brackets 32, and links 28 connect pivotally with the lugs 27 and with the front ends of the seatbars, the latter connection being made at 32. The links 28 extend rearward beyond the pivots with the seat-bars and bend under the seat-bars at 29 to form rests on locks therefor. Set screws, as 30, are preferably inserted through bends 29 to engage the scatbars and adjust the resting positions thereof.

Vhile the device is used as a riding-cultivator, the seat-bars are in the position shown in Fig. 1, resting on the axle and sustained from further downward swing by contact with the rearward extended ends of the links. The links are pushed forwardby the seatbars and held in horizontal positions, and so the cross-shaft is forced as far as possible from the axle, and the cultivator-beams are held well forward in position to be operated by the feet of the driver sitting on the seat. /Vhen it is desired to use the invention as a walking-cultivator, the seat-bars are raised at their rear ends, as shown in Fig. 2, the front ends of the seat-bars are swung under and to the rear of the axle, and the links 28 follow the motion and carry the beams back into the desired position by the time the seat reaches the termination of its forward swing.

The pivot of the seat-bars is on the axle, and the connections of the links are with the cross-shaft or with the slides adjacent thereto, and so the means for making the convertible shift are simplified and improved.

It is a matter of convenience to have the seat on the bars that shift the beams and the adjuncts thereof; but it is obvious that the bars do the shifting independent of the seat, and we do not confine ourselves to the application of seat-bars to the shifting operation.

When the cultivator-beams are in the positions shown in the drawings, the cultivating-shovels should be in operative positions in the soil, and the chains 25 are taut, so that further downward movement in the beams will be resisted by the cushion-springs 24:. The lift-springs are under tension in the positions shown, and they nearly or quite counterbalance the weight of the beams and assist materially in raising the shovels or other cultivating devices clear of the ground.

The lift-springs perform the function common to their class by offering a somewhatweak resistance to the entire downward swing of the beams, while the cushion-springs act rather stubbornly while the shovels are in the ground and are inoperative at other times. The backward inclination of arms 20 permits the beams to be raised well out'of contact with the ground without throwing the arms inconveniently forward, and the disposal of all the parts is compact, convenient, and simple.

The connections between the bars 4 and links 28 are in the nature of rule-joints, free swing being provided in one direction but not in the other, and the specific form shown may be varied considerably without departing from the principle of our invention.

We claim- 1. The combination in a convertible cultivator of a wheel-supported frame, a crossshaft mounted slidably on the frame, cultivator-beams swung from the extended ends of the cross-shaft, links connected with the cross-shaft and bars pivoted on the axle of the frame and joined to the links, substantially as described.

2. The combination in a convertible cultivator of a wheel-supported frame, a crossshaft mounted slidablyon the frame, cultivator-beams swung from the extended ends of the cross-shaft, links connected with the cross-shaft and seat-bars pivoted on the frame and connected with the links rule-joint fashion, substantially as described.

3. The combination in a convertible cultivator of a wheel'supported frame, a crossshaft mounted slidably on the frame with its ends extended beyond the sides thereof, sleeves mounted loosely on the extended ends of the shaft, vertical sleeves fastened on the sleeves on the ends of the cross-shaft and cultivator-beams having upturned ends journaled in the vertical sleeves, substantially as described.

4. The combination in a convertible cultivator of a wheel-supported frame having parallel side bars, slides on the side bars, a crossshaft connected with the forward ends of the slides and extending beyond the side bars,

sleeves mounted loosely on the ends of the cross-shaft, vertical sleeves fastened to the sleeves on the ends of the cross-shaft, cultivator-beams having upturned ends journaled in the vertical sleeves, arms fastened to the sleeves on the ends of the cross-shaft, such arms having bell-crank extensions, liftsprings connected with the swinging ends of the arms and with relatively stationary extensions near the pivots of the arms and cushion-springs connected with the bell-crank extensions of the arms and with extensions of the slides in the rear of the axle of the supporting-frame, substantially as described.

5. The combination in a cultivator of a supporting-frame, a cross-shaft having its ends extended beyond the sides of the frame, cultivator-beams pivotally mounted on the extensions of the cross-shaft, bell-crank rockarms pivoted on the extensions of the shaft and partaking of the rocking motion of the beams, lift-springs connected with each of the principal members of the bell-crank rockarms and with relatively stationary extensions near the pivots of the arms and cushionsprings connected with the secondary members, of the bell-crank rock-arms, substantially as described.

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