This invention relates to ground working devices and particularly to those ground working devices which are adapted for harrowing, rolling and for breaking up clods at the same operation.

The tendency of modern practice in soil working and tilling devices is to work a wide path and to perform two or more operations at the same time. In making implements and machines of more complex type and of greater size, the problem is made more clifficult because of the irregularities of the ground. I p

The primary object of this invention is the provision of an improvedmeans for harrowing, rolling and clod breaking with means for effectively connecting the parts together while at the same time permitting of proper action on the irregular surface of the ground and also permitting of .easyturning as at corners. i

Other and further objects of my invention will be apparent from a reading of the complete specification and claims. 1

Referring to the drawing whereinlis illustrated an embodiment of my invention,

In the drawing, in order to show thevari.

ous parts as large as possible, the widths of the elements have been made less than is preferred in practice. In practice, the cultipacker and roller elements would preferably be relatively longer on their axes than illustrated. I

r Similar reference characters refer to the same or similar parts throughoutthe views of the drawing. 7

In the herein illustrated embodiment of this invention, there are illustratedasa part so of the complete implement a cultipacker, a

spring tooth harrow and a roller, each being constructed in two parts. In tractor-drawn s-oilworking devices having great width, it has been found that more efficient results can be obtained by constructing the soil working devices in two parts. Such construction has a tendency toprevent the leaving of spaces between implement paths. Nith the increase in the width, and theincrease in the number of devices com prising the implement, the problem of construction of a frame of proper strength and flexibility and of proper connections there 7 for, presents itself. Q g r In the drawing 10, and 10 designate the two elements which comprise the'cultipacker which is illustrated as theforward device of the implement. The cultipacker elements 10, 10 are mounted in suitable frames. At the ends of the elements 10, .10 are trunnions 11, 11 which are journaled for rotation in suitable bearings 13, 13. Bolted to the bearings 13, 13 are forwardly and rearwardly extend in-g substantially identical frame members 14 14. 1

Connecting the forward ends of the respective pjairs of frame members 14, 14 are the cross framemembers 15, 15. Connect ing the rear ends of the respective pairs of rear members 14, 14 are the rear cross frame members 16, 16. I I p Bow members,17,17 are secured adjacent the outer ends of the members 14:, 14: respectively. Connecting the upper portions of thepairs of bow-membersl 'l and 17 are the top cross-connecting:members 18, 18.

At the forward side of the frame members 15, 15 are secured suitable securing means toprovide connection to the tractor when Q theunit is used in a forward position or to connect to a forward device when the cultipacker is used in rear of another ground working device.

The securing means for connection to the tractor are designated 19, 19 respectively and are located in the middle of the frame members 15, 15. To these securing means 19, 19 maybe secured devices 20, 20 or other tractive elements for connection to suitable til 'vided with vertical openings to secure the cultipacker to the rear of the harrow frames when the cultipacker is used as a rear unit. Secured loosely at therear sides of the respective rear frame members 16, 16, each by a single bolt, 27, 27 are U shaped devices 27, 27. These devices serve to connect the forward'end of the harrow devices to the cultipacker.

Because of the movement permitted through this connection 27 or. 27, the unit forward as the cultipacker 10 is permitted to tilt from side to side relative to the unit following behind, as the harrow, to be now described.

The harrow devices comprise each a frame 7 . member 28, 28 which is preferably of U-shape with the lower part of the U in a forward position. At the point of these frames are securing members 29, 29 which are secured to the U-shaped devices 27, 27 respectively and loosely by the cylindrical shanks of guide shoes 30, 30. The guide shoes are held in place by suitable cotter keys at their upper ends. In the connections 27, 29 and 27, 29 there is suflicient play to permit of the following of the contour of the ground.

Extending from side to side of the frame members 28,28 respectively are pivoted sets of spring harrow teeth 31, 31. An arm 32,

32 extends from each set of harrow teeth 31,

31 in such a way as to be connected to parallel motion links 33, 33 to cause movement of all of the teeth sets31 together and all of the sets of teeth 31-together.

The rearmost arm 32, 32 of each barrow section is extended to form the levers 34, 34. About the center of the connecting bolt tween the rearmost lever 32, 32. of each set and the respective. rear ends of the links 33,

33 are segmental racks 34", 34 The levers 34, 34 are provided with the usual detents and grip lever for operating the detents through suitable rods shown in Figure 2.

The detents cooperate with the notches of the racks 34, 34". By releasing the detents from their cooperating notches, the desired angle of the teeth 31, 31 may be obtained. When the gripping means are released the detents again register with their respective notches and the teeth are thereby held in the desired position.

forwardmost The fronts of the frames 28, 28 of the harrow sections are connected to the forward unit, each by a single connection as already described. They are connected together at their adjacent sides by angular parts secured to the sides and forming with the pivot rod hinge connections 28*. At the rear end of the frame 28, is located a connection 36, whichis connected to the rear unit by the link 37. The outer rear corners of the frames 28, 28 are connected to the respective rear units by links 37 and connections which are designated 35, 35.

It will be noted that each of the connection members 35, 36 and 35 has two openings, one of the connective openings being for connection to the respective Z-shaped members 37 and the others to receive bearing portions of guide shoes 38, 39 and 38. The bottoms of these guide shoes rest upon the ground and provide a bearing support for the harrow frames 28, 28'.

The rear ends of the links 37 are secured to connections on the rear element corresponding to the connections 23, 26 and 23.

'I will now describe the roller implement shown as the rear unit of the whole.

The roller implement comprises two rollers, 110 and 110 constructed similarly to the cultipacker rollers 10, 10 except that the rollers 110 and 110 are illustrated as having smooth cylindrical surfaces.

The rollers'llO, 110 are provided with shafts or trunnions 111, 111 respectively similar in operation to trunnions 11, 11. The bearings 113 and 113 are similar in construction to the bearings 13, 13 and are connected to forwardly and rearwardly extending frame members 114, 114 similar to frame membersl4, 14. Forward frame members 115, 115 are similar in construction to frame members 15, 15 andv rear frame members 116,116 are similar to frame members 16, 16 already described. Connected to the forward frames 115, 115 are securing means 123, 123, pivoted links 124, 124 and a securing member 126, similar in construction and operation, respectively to the parts 23, 23, 24, 24,

26 already described.

- The rear frames 116, 116 are respectively provided with U-shaped members 127, 127 constructed similarly to the LJ-shaped member 27 secured to the frame member 16. The adjacent ends of the frame members 116 and 116 are connected together by links 124, and 124*.

The frame members 114, 114 have secured to them the bow-shaped members 117, 117 and at the'tops of the bow-shaped members 117, 117 are top frame members 118, 118.

Pivoted rearwardly of the top frame members 118, 118 and in each pair of bow members 117 of one roller and 117 of the other roller, are scraper devices 140, 140. These 7 gage the openings of the segmental racks 144,

l44 to hold the scraper members in any desired adjusted position.

The frame members 14, 14 and 114, 114 are each made in one piece anddepressed at the middle to receive its bearing.

A seat supporting bar 145 is secured to the pivoted link 124" and supports a seat 146 which is secured to the'center of a seat equalizer support 147. This support 147 is provided at one end with a casting 148 which is shaped to receive the support 147 and yet have a sliding engagen'ient therewith. The opposite end of the support 147 is supported 011 the top frame member 118 by two pads and a double eye bolt passing through the two pads, the frame member 118 and the support 147 as shown at 149. Each of the pads is provided with a hole passing therethrough and also with a depression, the depressions being at from each other and of a shape to receive the eyes of the eye bolts. The eye bolts which have their eyes linked are inserted, one in each depression and the parts are then assembled. The bottoms of the depressions are so located as to leave a slight clearance between adjacent sides of the pads when the nuts are tightened on the eye bolts, each of. the eyes of the bolts being loose relative to the other. This permits of sufiicient play between the parts.

The connection 149 permits of pivotal movement and the casting 148 permits of sliding movement. In this way the support 147 does not interfere with the operation of the two rollers over uneven ground.

It will be noted that with this invention, the three units will operate successfully over uneven ground without undue strains in the frame members. The first unit, as the'cultipacker, is permitted, because of the connec tion 27 or 27 to have a side to side tiltin 7 2D movement without bringing strains in the frames of the harrow'or roller which follow. Such a side to side tilting movement might be the tilting movement which would result from one end of a cultipacker roller striking a stoneor falling into a hole. At the same time that this independent movement is permitted by the forward connection, the connections 37 hold the rear ends of the harrows in their relation to the rollers which follow, and prevent the relative side tilting which the connections 27, 27 facilitate.

During turning, the connections 3'? facilitate the turning movement by permittingrelative bodily movement in .a horizontal plane and when these members 37 are, themselves, located in parallel, vertical planes as shown, the fore and aft axes of forward movement of the two devices as the harrow and roler are thrown out of alignment while still maintaining these axes in parallel reation during the turning operation. t
