8 Claims. (01. 97-4981) This invention aims to provide novel means whereby soil-engaging elements "may be assembled with the beams of a cultivator, in adjusted positions. i

It is within the province of the disclosure t improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention 'herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of theinverition.

In the accompanying drawings:

Fig. 6 is an end view of the structure depicted in Fig. 5;

Fig. '7 is a top plan of the structure shown in Figs. 5 and 6; 1 I

Fig. 8 is an enlarged sectional view showing a portion of the structure appearing in Figs. 5, 6 and '7; v

Fig. 9 is a perspective view showing the supplemental beam.

In Figs. 1 and 2, cultivator beams are shown at l. Hangers 2 are provided, and each hanger includes a first arm 3 and a second arm 4 arranged at right angles to the first arm 3, the hangers 2 being twisted, as shown at 5, at the juncture between the arms 3 and 4, so that, so far as major transverse dimensions are concerned, the arms 3 and 4 are in planes at right angles to each other. The hangers 2 need not be of the precise construction shown and described, especially as to the twist shown at 5, and the hangers may be of any preferred form in which the general rectangular relation between the arms 3 and 4 is substantially preserved. By means of clips 6 and securing elements I, the first arms 3 of the hangers 2 are secured for vertical adjustment to the cultivator beams I.

Brackets are provided, and one of the brackets disclosing, one of v 5.2: is shownin Fig. 3, the bracket being designated by the numeral 8. Each bracket comprises a first or vertical depending flange 9 and a second or horizontal flange Ill. The flanges 10 of 1 the brackets Son the respectivebeams project out- 3 wardly in opposite directions with respect to the median plane of the implement. There are spaced lines of openings H in the flange 9, and spaced lines of openings l2 in the flange It]. By means of securing elements [4, mounted in one I) of the lines of openings I2, the second or horizontal arms 4 of the hangers 2 are connected to the second or" horizontal. flanges H] of the brackets 8. Securing elements I5, mounted in any k one of the lines of openings I2, attach the hori- 15 zontal shanks iii of soil-engaging elements I! to the flanges N3 of the brackets 8. The securing elements I5 may be mounted in any of the lines of openingsiZ, and, thus, a horizontal adjustment between the soil-engaging elements I! may be r20 brought about, A vertical adjustment may be secured by shifting the first arms 3 of the hangers 2 in the clips 6. Figures 1 and 2 show one of the simplest applications of the'invention.

In Fig. 4, parts hereinbefore described have: been designated by numerals previously used, with the suffix a. The flangesv Illa of the brackets 8a of the respective beams la project inwardly with respect to the median plane'- of the implement. Brackets I 8, constructed like the brackets 8 are provided. The vertical arms I!) of the brackets i8, corresponding to the arms 9a, are attached tothe arms 9a by securing elements 20. The arms or flanges 2| ,of the brackets l8 extend outwardly, and to them the shanks of soil-engaging elements 22 are secured, as shown at 23, by means of bolts or the like, mounted in the openings corresponding to the openings l2 of Fig. 3. ,It will be observed that an in and out horizontal adjustment of the soil-engaging elements 22 is possible. The arms 3a. of the hangers nearest to the median plane of the implement are caused to extend upwardly instead of downwardly and the arrangement of parts is such that the soil-engaging element can work upon a ridge 24 of considerable height.

In Figs, 5, 6 and 7, parts hereinbefore described have been designated by numerals already used, with the suffix b.

In this arrangement, the brackets IBb, corresponding to the brackets lBa are used, but they extend upwardly, instead of downwardly as in Fig. 4.

Extension bars 25 are provided and have countersunk openings 26 adapted to receive secur 55 ing elements 2'! which attach the extension bars to the flanges lb and 2lb of the brackets 8b and IE1) respectively. The extension bars 25 may project either rearwardly or forwardly, as shown in Fig. '7, and the shanks 28 of the soil-engaging elements 29 are overlapped upon the extension bars 25 and are attached thereto by securing elements 30. Because the extension bars 25 may be made to project either forwardly or rearwardly, the soil-engaging elements 29 may be spaced apart, longitudinally of the draft line, the extension bars 25 having openings 3! for the reception of the securing elements 3!]. A transverse adjustment of the soil-engaging elements 29 also is provided, owing to the presence of the lines of openings 12b in the flanges 21b and lllb of the brackets 8b and 181) respectively.

It will be observed that numerous horizontal and vertical adjustments are possible in the positions of the soil-engaging elements, the arrangement of parts shown in Fig. 6 being of peculiar utility whenthe soil-engaging elements 29 must work in a hollow, the soil-engaging elements 22 of Fig. 4 being adapted to work on a ridge, and the soil-engagmg elements H of Fig. 2 being adapted to work on comparatively level ground.
