EMMA K. REIHER, O1? CARLINVILLE, ILLINOIS.

DOUBLE-ROW CULTIVATOR.

To all whom it may concern Be it known that I, EMMA K. REIHER, a

citizen of the United States, residing at Oarlinville, in the county of Macoupin and State of Illinois, have invented a new and useful Double-Row Cultivator, of which the following is a specification.

This invention relates to riding cultivators adapted to cultivate atone time through the entire width on both sides of a central row between two outside rows.

The purposes of the invention are :-to provide a main frame adapted to straddle three rows with the supporting wheels on the outside of the outer rows and the middle row under the center of the machine; to provide plow beams of improved construction; to

provide improved means connecting the plow-beams with the main frame; to provide improved means connecting the en].- tivator teeth or blades with the beams; to provide supporting wheels of improved construction; to provide improved means connecting the seat with the frame; and to provide other new and useful features of construction. i l

The invention is illustrated 1n the annexed drawingto which reference is hereby made and is hereinafter described and finally recited in the claims.

Figure 1 is a rear elevation of the complete machine. Fig. 2 is a top plan of the machine. Fig. 3 is a vertical section on the line X. X. of Fig. 2. Fig. 4 is an enlarged detail of one tooth and the means connecting it with the beams, and Fig. 5 is an enlarged detail of the seat and its connection.

Similar reference characters designate like parts in the several views. 4

The axle 1 is preferably of steel channelbar, but may be of other suitable material. At theends of the axle are spindles 1 on which the supporting wheels 4 turn.

The wheels 4 which may be of any suitable diameter have flat treads 4 and rounded fellies 4, adapted to permit dirt to roll off the fellies without being carried upward on the wheels, thereby materially diminishing and extends horizontally forwardly of the axle.

Specification of Letters Patent.

Patented Oct. 27, 1914.

Application filed July 7, .1911. Serial No. 637,285.

A rearwardly extending horizontal brace 3 is secured on the axle l by bolts 17 which also serve to connect the front brace 9. with the axle.

The seatsupport is preferably a springy steel bar 9 bent to form two parallel members i and each member having at its inner end a hook 9 adapted to hook under the axle. The rear part of the bar 9 is quarter-turned to form a loop 9 accommodating a bolt 10 extending vertically through and slidable in the loop and connecting the seat 10 with the bar 9 so that the seat may be placed in different positions on the bar in order that the weight of the driver on the seat may balance the weight of the tongue and other parts forward of the axle, and thereby keep the weight off the horses necks.

The space between the forward extending member of the seat-support permits the operator to see the central row of corn under the seat-support.

The central parts of the members of the bar 9 rest on the upper edge of the rear brace 3, and the brace 3, in conjunction with the hooks 9 hooking under the axle 1 support the bar 9 and the attached seat 10 so thatthe seat may be easily removed without the use of tools.

The plow-beams 5 are steel-bars having lengthwise channels 5*. The ends of the beams adjacent to the wheels are curved upwardly as shown. The upper part of each beam is pierced by a series of holes 5 accommodating clevises 12 flexibly connecting the beams with the axle. By changing the clevises from one hole to another the front ends of the beams may be raised, or lowered, to suit the work in hand.

Rectangular blocks 6 fit in the channels in the beams and the walls of the channels keep the blocks from turning. Each. of the blocks 6 has holes 6 accommodating bolts 6 which extend through corresponding holes 5 in the beams 5 and detachably connect the blocks with the beams so that all, or some,

of the blocks may be used according to circumstances. The blocks 6 have vertical square notches 6 accommodating the square teeth 7.

The inclination of the plow beams relative to the line of draft of the machine is such that when the teeth are in place on the beams the front edges of the teeth will serve as cutting edges.

5 Pointed steel teeth 7 of square cross-section are fitted to slide in the notches 6 and the front faces of the teeth contact with the rear faces of the beams and the vertical front edges of the teeth serve as cutting 10 edges, and as the machine progresses over the ground the teeth traverse the entire width between the rows and cut and pulverize the soil.

The rearwardly extending beams 5 incline downwardly and the teeth 7 connected with the beams are relatively short near the lower ends of the beams and longer near the upper ends of the beams, as shown in Fig. 1.

Set screws 8 screw into the blocks 6 and the points of the screws bear on the sides of the teeth 7 to keep the teeth in place. By loosening the set screws 8 the teeth may be raised or lowered and the set screws may then be tightened to secure the teeth in the "positions in which they are set.

Brace-plates 13 extending forwardly and upwardly have their lower ends rigidly connected with the beams 5 respectively. Each brace-plate 13 has nearer its upper end a series of holes 13. Suitably spaced staples or eyes 18 on the axle 1 accommodate clevises 19 which lit in the holes 13 in the upper ends of the brace plates 18 (Fig. 3) and flexibly connect the brace-plates with the aXle. By placing the clevises 19 in different holes 13 in the brace plates the height of the front ends of the brace-plates may be' changed at pleasure, to maintain substantial horizontality of the beams running on level 40 ground, or to incline transversely, either beam, or both beams to suit the surface of sloping ground.

The plates 13 rigidly connected with the beams 5, the eyebolts 18 connected with the axle 1, and the clevises 19 connecting the plates with the eye bolts, together constitute draft connections normally keeping the rear ends of the converged beams close to the central row which is being cultivated.

Sheaves 20 provided with hooks 21 are mounted on the rearwardly projecting tongue members.

Chains 22 have one end connected with the plow beams 5 respectively and pass around the sheaves 20 and the chains have stirrups 23 at the lower ends of the chains adapted to accommodate the feet of the driver. The chains 22 have large links 22 adapted to hook on the hooks 21, to support the plowbeams when the cultivator is on the road.

Stirrups 24c secured on and extending downwardly from the beams 5 support the operators feet. If the ground is hard and the driver wishes to force the teethinto the 6,5 groundhe will press with his feet on the stirrups 2 1. If he wishes the plows to pass an obstruction or if it is desirable in the course of the work to movethe plows laterally within the scope of the flexible connections 18, 19 and 12 he will use his feet in. the stir- 7 rups 2 1 to give limited lateral movement to the beams. If it is necessary'to raise the plows to pass an obstruction he will place his feet in the stirrups 23 and push them downward to raise the beams and when the obstruction has been passed will remove his feet from the stirrups 28 and the beams will gravitate to normal position. i

To support the plows when the machine is on the road the stirrups 23 will be pushed so downward and the links 22 will be hooked onto the books 21 to support the plow beams in their raised position.

Having fully described-my invention what I claim as new and desire to secure by Letters Patent is 1. In a cultivator, the combination of an axle; wheels rotative on the axle and spaced to straddle three rows; outer eyes on said axle adjacent to the wheels respectively; intermediate eyes on the axle between said outer eyes; two upwardly curved and rearwardly converged beams having a series of holes near the upper end of each beam; two clevises respectively engaging in said outer eyes on the axle and adapted to engage in any hole of the series of holesin said beams respectively; upwardly inclined brace plates rigidly connected with'the beams respec tively and having a series of holes near the upper end of each brace-plate; and two clevises respectively engaging, in said intermediate eyes on said axle and adapted to engage in any hole of the series of holes in said brace plates respectively.

2. The combination of a straight axle extending across the central row and two outside rows which are to be cultivated; wheels rotative on the axle and spaced apart to run on the outside of the outside rows respec- 11 tively; two upwardly inclined and rear-, wardly converged beams having their forward ends flexibly and adjustably connected with the axle,theforwardends ofsaid beams being adjacent'to the wheels respectively; inclined brace-plates having their lower ends rigidly connected with the beams and their upper ends adjustably connected with the axle; tilling devices connected with one beam and adapted to till the space between the central'row andone outside row; and tilling devices connected with the other beam and adapted to till the space between the central row and the other outside row.
