SPECIFICATION forming part of Letters Patent NO. 757,398, dated April 12, 1904. Application filed September 19, 1903. Serial No. 173,870- (No model.)

- is a specification.

This invention relates to cultivators, and has for its objects to produce a device of this character of generally improved construction having a pair of independently-operable cultivator-beams carrying blades to operate upon opposite sides of the row and to provide improved mechanism for supporting the beams which will permit of the latter being moved independently in a direction transversely of the machine or vertically downward under pressure for entering the blades into the ground, said mechanism being adapted when the beams are relieved from pressure to automatically return them to normal elevated position.

With these and other objects in view the invention comprises the novel details of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a top plan view of a cultivator embodying this invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail perspective View. Fig. A is a detail plan View. Fig. 5 is a detail perspective view of one of the journal-boxes. Fig. 6 is a detail vertical section through one of the beam-pivoting members.

Referring to the drawings, 1 indicates a frame of substantially U shape in top plan and comprising an upper plate 2 and a lower plate 3, spaced vertically one above the other, said plates being of substantially U form and each consisting of a pair of slightly-diverging side bars and a crown portion connecting the forward ends of the bars. Thusthe frameplates when assembled present a pair of spaced transverse front bars 4 and two pairs of spaced longitudinal side bars 5, the lower side bars 5 being bent upwardly at a point adjacent to their rear ends and riveted or otherwise secured to the lower faces of the upper side bars.

6 indicates the tongue or pole which lies between the front bars 4 and is seated at its rear between and secured to a pair of transverse plates or braces 7 and 8, extending, respectively, between and overlying the upper and lower side bars 5, the upper plate 7 being of L form incross-section and presenting an upstanding flange, the purpose of which will presently appear. These braces are attached to the frame-bars by vertical bolts extending through and common to all of the parts and which serve to secure in place spacing-blocks 9, disposed between the plates 2 and 3.

1O designates an axle journaled in boxes or bearings 11, disposed one between each pair of the side bars 5 and having downwardly-extending crank-arms 12, upon the horizontal portions or spindles 13 of which the transporting-wheels 14 are mounted for rotation, the axle being susceptible of a swinging or rocking motion of its arms 12 in a vertical plane for raising and lowering the frame 1 in the manner and for the purpose hereinafter described.

The boxes 11, which serve as an additional means for spacing the frame-plates 2 and 3 and are secured in position by vertical bolts 15, each comprise an upper section 16 and a lower section 17 The lower section of each box has formed upon its outer face a horizontal outwardly-extending lo0p'18, through which the adjacent crank-arm 12 extends and by the end walls of which the said arm is limited in its rocking or swinging motion, while the upper section of each box has formed upon its rear end an inwardly and forwardly extending angular portion constituting a bearing plate or finger 19, the purpose of which will presently appear.

20 20 indicate apair of castings disposed one on either side of the tongue and adjacent to the outer ends of the transverse bars 4:, between which they are disposed, as shown in Fig. 6. These castings, which are pivoted to swing in a horizontal plane, each has at its forward end a pair of vertically-disposed oppositely-extending substantially conical bearing members or studs 21, seated in coincident sockets 22 23, formed, respectively, in an upper bearing-plate 24, recessed upon its upper pair of cultivator-beams 28. IO

faceto receive the upper transverse bar 4, and a lower bearing-plate 25, recessed upon its under face to receive the lower transverse bar 4, said plates and casting being secured in place by a vertical through-bolt 26. Each casting has a rearward extension bifurcated to form a pair of bearing-plates 27, between which is pivoted the forward end of one of a The beams 28, which swing upon their pivots in a vertical plane, are each curved downwardly and rearwardly from its point of attachment with the casting and merges into a substantially horizontal portion to which is attached a plurality of cultivator blades or shovels 29.

The cultivator-beams 28 are independently and floatingly sustained at predetermined positions relative to the ground each by means of a suspending mechanism 30, which permits of an independent movement of the beams in a direction transversely of the machine for brin ing the blades to the proper position relative to the row and an independent vertical movement which permits the blades through pres-- sure on the beams being entered the proper depth into the ground.

' The suspending mechanisms 30 each consist of a hanger 31 in the form of a substantially vertical rod pivoted at its lower end to the beam 28 at a point adjacent to the rear of the latter and provided at its upper end with a swiveled head or fork 32, the jaws of which straddle atrack or guide 33 and have pivoted between them for travel upon the track a wheel or roller 34. The track 33, which extends in a direction transversely of the machine, is formed by the crown portion of an approximately U-shaped frame disposed in inverted position, with the lower ends of its Vertical arms or bars 35 secured in suitable sockets or seats formed in a casting 36, mounted upon the axle 10. Each of the castings 36 has two pairs of spaced ears 37, which embrace the axle, an outwardly and rearwardly extending angular portion forming a bearing-plate 38, which engages the finger 19 on the adjacent journal-box 11 for preventing movement of the casting longitudinally of the axle, and an upwardly-extending bifurcated arm 39, the purpose of which will presently appear, the casting being loosely secured to the axle for free rotation thereon by means of bolts 40, extending through the cars 37.

41 indicates a link or member pivoted at its rear end in the bifurcated arm 39 of the casting and provided on its upper edge with a perforated ear 42 and at its forward end with a series of longitudinally-arranged perforations 43, any one of which receives a bolt 44, by which the link is pivotally connected with the rear end of a link 45, pivotedat its forward end to an eyebolt 46, engaged with the upstanding flange of the angular brace-plate 7. These links, which serve to limit the rearward swing of the casting 36, and consequently the depth of entrance of the blades into the ground, are adjustable through the medium of the perforations 43 and bolt 44 for varying such movement of the casting, a further adjustment for this purpose being possible through means of the eyebolt 46,. and are acted upon by a normally contracted spring 47 for maintaining the parts in normal position with the cultivator-blades lifted out of the ground, said spring serving to automatically lift the blades from (after they have been relieved of pressure for entering them into) the ground. The spring is attached at its rear end to ear 42 and at its forward end to an elevated portion of link and is adapted to rest between its ends in a semicircular seat 48, formed at the upper end of an upwardly-projecting lug carried by the link 45, by which arrangement the spring is caused to positively insure the links breaking joint for return to normal position.

Secured in rear of the casting is a pair of outwardly-diverging fingers 49, which guide the hanger 31 inward toward the casting as the latter swings in a forward direction.

Secured to each of the hangers 31 is a hand loop or piece 50, to be grasped by the operator for moving the beams in their transverse travel, and attached to each of the beams is a stirrup or foot-piece 51, to be engaged by the foot of the operator for depressing the beams and entering the blades into the ground.

Pivoted to each of the lower side bars 5 of the frame, adjacent to its forward end, is a draft-bar 52, to which the swingletree is connected, these draft-bars being connected for uniform movement by means of a rod 53, extending transversely of the machine.

' 54 designates a transverse strap engaged at its ends with vertical studs or posts arising from the bars 5, adjacent to their rear ends, and 55 a seat attached to the strap,while 56 is a lever secured to one of the frame-bars 5 within convenient reach of the driver and having pivoted to its lower end a pair of links 57 ,engaged with the horizontal portion 13 of one of the crank-arms 12, whereby the axle may be rocked for raising and lowering the frame 1 relative to the ground to correspondingly raise and lower the beams 28,and thus obtain an initial adjustment of the blades 29, the levers being adapted for engagement with a rack 58 for locking the parts in their adjusted positions.

From the foregoing it is apparent that the ably increasing the depth of entrance of the blades into the ground, the springs 47 serving at all times to automatically return the beams to their initial position, as heretofore explained. It is also obvious that the beams may be moved independently toward and from the row of plants, thus varying their working.

positions relative to the latter, and that such movement of each beam will be in a uniform plane.
