9 Claims.

The object of my invention is to provide a novel transplanter which can be attached to opposite sides of a tractor and which will make a furrow on each side thereof; to provide automatic means for discharging water into the furrows, and to provide means for packingdown the soil around the furrows after plants have been placed in them; to provide a seat for each of the operators who perform the transplanting as the machine forms the furrows; to provide novel means for raising this seat, and to provide novel means for regulating the operation of the mechanism when obstacles are encountered.

It is also an object of my invention to provide a novel arrangement of parts as shown and described.

I attain these and other objects of my invention by the mechanism illustrated in the accompanying drawings, in which- Figure l is a top plan view illustrating my transplanter attached to a tractor, a portion of the tractor being broken away and most of the transplanter on the left hand side of the tractor being omitted;

Fig. '7 is an enlarged detail top plan view of the journal bracket, shown supporting a shaft carrying spaced fingers;

Fig. 8 is an enlarged plan view of the bracket which supports the measuring wheel; and

Fig. 9 is a plan view of an enlarged scale of the transplanter mechanism, parts of the mechanism being broken away.

Referring to the accompanying drawings, there is illustrated a tractor chassis I, having front wheels 2, rear wheels 3, mounted on axle 4, a conventional seat 6, a conventional steering wheel 6, and a water tank I. Extending from the water tank is a pipe or hose 8, which extends longitudinally of the tractor and connects with the transversely extending water pipe or hose 9,

which terminates in a pair of opposite valvecontrolled nozzles Ill.

The tractor has a rear tool mounting bar I I, and a front tool mounting bar I la, as shown in Fig. 1, a rear inner clamp l2 and a rear outer 5 clamp 29 attached to the rear tool mounting bar II, and a front inner clamp l3 and a front outer clamp l5 secured to the front tool mounting bar Ila. A horizontal bar It is attached at its forward end to inner clamp l3 and at its rear 10 end to inner clamp I2. A stationary frame member I6 is secured to outer clamp I5. An approximately vertical bar I! extends downwardly from clamp I5 and to the lower end of this bar is pivoted a lower link Illa. The other end of the lower link |9a is pivotally connected to a seat frame member 2|. This frame member 2| has rigidly secured thereto an upstanding brace frame '20 which is of an inverted V-shape, as shown in Fig. 2. To the upper end of frame is pivotally 20 connected one end of an upper link I9, the other end of the link being pivoted to clamp I5. The aforesaid frame member 2| and another like inwardly disposed member 2| form part of a lower frame 2| carrying an operators seat 22. A brace member l8 extends from bar I1 to the rear end of frame member IE on each unit. Members I4, I6, I! and I8 form an upper frame to which the lower frame 2| is connected by means of links l9 and |9a and frame 20. To protect the 3 operator, his seat is provided with a suitable upright or slanting back 23, asshown in Fig. 2.

A suitable brace or braces 24 secure the back 23 to the member 2|. A bar or angle piece 25 is fastened to the under side of seat 22 and to the offset upper end of this angle piece 25 is attached a link 26, which in turn is pivotally connected at its upper end to an arm 21 mounted on a shaft 28, which shaft is secured to the lower end of a seat adjusting lever 3| and operated thereby. Referring to Figs. 1 and 2, there are two like arms 21 and two like links 26 on each side of the machine, or four of each altogether. Seat adjusting lever 3| is pivotally mounted on member 29 which carries a segment 30 with which the latch 3 a on lever 3| is releasably engageable.

As shown in Figs. 1 and 3, a furrow-forming shoe 32 is secured to the forward end of the lower frame 2| by bars 32', this shoe having a cut-away rear portion 33 and carrying metal strips 34a and trailing tilted ground packing wheels 34, as shown in Fig. 1, to pack the soil around the transplanted plants. There is a distance of approximately two inches between shoe g V and wheel.-

Bolted or otherwise aflixed to the sides 2| of seat 22 is a bridge element 35, as shown in Figs. 3 and 4 carrying an adjusting screw 36 which is secured in adjusted position by nuts 31. The lower end of this adjusting screw carries a clevis 59 to which in turn is .pivotally attached a link 5|, which is attached to the shoe 32. Also afllxed to and integral with bridge 35 is an upstanding apertured bracket 38. One end of a spring 39 is .secured to bracket 38 and the other end of spring 39 is adjustably secured to a hook 39a which is secured to the upper end of a bracket 49, as shown in Fig. 9. Bracket 49 is shown in detail in Fig. 8 and has spaced rearwardly extending arms 4|, as shown inFig. 3, on which an axle 42a of a measuring wheel 42 is mounted. Axle 42a revolves with measuring wheel 42. A sprocket 43 is also rigidly mounted on axle 42a and revolves with it. A sprocket chain connects sprocket 43 with a smaller front sprocket 44 which is mounted on and rotates with a cross shaft or 'axle 49. Thisaxle or cross shaft 49 extends considerably beyond sprocket 44 and carries spaced fingers 46 which rotate with shaft 49 and sprocket 44.

Suitable brackets 41 carry journals 48 which support the extended portion of axle or cross shaft 49, as shown in detail in Figs. 6 and 7,- and bracket 41 is suitably secured to frame member 2|. A flat bar 53 extends longitudinally of the machine parallel with the frame members 2|, as

shown in Figs. 1 and 3, and at its rear end has an upward projection or cam hose 54, as shown in Fig. 3, which engages and intermittently lifts a joint 55 on a pivoted lever 52 to which is pivot-- ally attached. a depending rod 51, the rod 51 carrying a ball valve 58 which normally seats in a valve seat in nozzle l9 and which is unseated by lifting of rod 51 to discharge water, as shown in Fig. 3. Pipe 9 is suitably supported on the tractor frame, as indicated in Fig. 1.

Aflixed to a bar 53, as shown in Fig. 3, is a finger 59 to which is attached a spring 69, the other end of the spring being anchored to a portion of the frame. Bar 53 also has affixed to it in proximity to the forward end of the bar, a finger 56 positioned to be operatively engaged by fingers 45 as they are rotated. In Fig. 3 the bar 53 has just been operated by the member 45 and has not yet been retracted by the spring 69. In

this figure the spring 69 has hardly begun its in its lowered position while the dotted lines show the lever 3| moved to a lowered position in which position the movement of the lever has raised arm 21, rod 26 and members 25; 2|, 22, 24 and 25 to a raised position, as indicated in dotted lines. This operation of the lever causes the links l9 and |9a to swing to the upper position indicated by dotted lines, thus raising the forward end of the seat at the same time that the rear end of the seat is raised by rod 26 and angle piece 25. The lift applied at 25 by link 26 lifts the platform as a whole. The right hand brace 29 connects the ends of links I9 and l9a; raising the free end of member I9 necessarily also raises the free end of I91: and vice versa. The left hand element 29'which is v 2,290,043 :2 and wheel 42, due to the shape of the'shoe plvotally connected to the free end of member 9 and afllxed at its lower end to member 2|,- makes the whole platform or operators seat 22 rigid.

The operation of the mechanism for periodically dumping water in the furrow where the plants have been or are to be transplanted is illustrated in Figs. 3 and 1. The rotation of the measuring wheel 42 which rolls along on the ground also rotates the sprocket 43 as both are rigidly mounted on the same axle 42a. The rotation of the sprocket 43 drives sprocket chain 45 and sprocket 44, which in'turn drives the axle or cross shaft 49. The shaft 49 rotates the fingers 46 which successively engage thefinger 56 afllxed to bar 53 and thus with each half revolution of the sprocket 44, moves bar 53 rearwardly against the tensionof spring 69, said spring thereafter returning bar 53 to its extreme forward position, in which position member 56 will b in position to again be engaged by member 46. As the bar 53 is moved rearwardly by the action of member 46 against member 56 the cam nose 54 of bar 53 engages joint 55 which is the connection between the lever 52 and depending rod 51, thereby raising depending rod 51 and valve 58. As the valve 58 is lifted from itsseat, 'water is released by gravity through nozzle l9 from transverse pipe 9,

*longitudinalpipe 8 and water tank I, thus water is discharged into the furrow which has been made by the shoe 32, the rear portion of the shoe being cut away at 33 to provide space for the nozzle l9, as shown in Fig.4. The plants are deposited in the furrow by the individual operator who is seated on the seat 22 and who leans to one side to place the plants in the furrow after it has been formed by the shoe 32.

As the bridge 31 afllxed to the frame 2| carries the bracket member 38 to which the spring 39 is attached, this spring in turn being attached by hook 39a to the bracket 49, rearward tension is thus exerted on bracket 49 which in turn tends to tilt arms 4| downwardly and thus exerts downward spring tension on the axle 42a to hold the measuring wheel 42 in tractive engagement with the ground. However, if an obstruction is encountered, the measuring wheel can rise against the tension of spring 39 to pass over the obstruction, as wheel 42 is fioatingly mounted.

The bridge element 35 shown in Figs. 3 and 4 being affixed to the frame members 2| of the seat 22 provides a support by which the adjusting screw 36 is adjustably mounted. This adjusting screw in turn is operatively connected by clevis 59 and link 5| with the shoe 32, whereby the depth of the furrow may be regulated by adjusting the position of adjusting screw 36 and consequently of shoe 32 relative to the bridge support 35. To adjust the adjusting screw 36, the lower nut 31 will be unscrewed to a lower position on the adjusting screw, and a wrench would then be applied to the upper nut 31, the turning of which against the upper surface of the bridge 35 raises the screw 36, and consequently would raise link 5| and shoe 32. A reverse operation would lower the shoe- Like transplanter mechanisms are provided on each side of the tractor and to which the respective nozzles l9 extend, only one of the transplanter mechanism being shown in detail in Fig. l to simplify the drawings.
