To all whom It/.may concern:

Be it known that I, LEWIS E. WATERMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certaln new and useful Improvements in Two-Row Cultivators, of which the followingis a specification.

The invention relates to improvements in in which the beams can be ralsed separately or in pairs, in which the four drag-bars are connected by a bail in two sections adjustably connected, and in which the drag-bars are moved transversely through the lever connection with the bail.

In the accompanying drawings, Figure 1 is a plan view of a cultivator containing my improvements. Fig. 2 isaside elevation. Fig. 3 is a transverse section of the drag-bars, showing the bail connection therewith. Fig. 4 is a vertical section on dotted lines b, Fig. 3. Fig. 5 is a plan view of the bail and its connection with thedrag-bars. Fig. 6 is an end elevation of the lifting-lever mechanism for the outer drag-bars. Fig. 7 is a front elevation of the same. Fig. 8 is a section on dotted lines a, Fig. 9, showing the lifting-lever mechanism for the inner drag-bars. Fig. 9 is a Fig. 10 is a cross-bar 6. Fig. 11 is a section on dotted lines b, Fig. 10. Fig. 12 is a perspective view of one set of lift- 1ng-levers,in which one lever is shown moved independent of the other. Fig. 13 is a similar perspective view in which both lifting-levers are moved by a movement imparted to one of them. F'g. 14 is a vertical section showing the counterbalancing arran ement. The main frame is composed of t le transwhich are connected the axles 2, supported by the'wheels 3. To the beam 1 are connected two poles 4 and 5, and

-a cross-bar 6 connects the poles forward of the axles. Brace-bars 7 connect the beam 1 and cross-bar 6, to which the poles are connected, and a seat-frame 8 has a connection with the brace-bars, and rests upon the beam 1 and supports a seat 9 in rear of the axle. To the cross-bar 6 is pivotally connected a shaft 69, havin depending ends 70, which are connected to til-1e axles by the links Four drag- bars 10, 11, 12, and 13 each have a vertical section 14, which is pivotally supported in the bracket 15, depending'from` the shaft 69, to which it is pivotally connect- Iver 42 near its upper end. A- toothed quaded. The lower ends of the brackets 15 have eyes 16 extending therefrom. A toothed quadrant 72 is supported by the cross-bar 6, and' a hand-lever 73 has a connection therewith and an engagement with the toothed uadrant. By means of the lever 73 the s aft 69 is rocked, which, through the link 71, connected to the axle, rocks the axle to balance the cultivator. pivoted two eveners 17 and 18. The inner ends of these eveners are connected by a bar 19, having a linked connection with the eveners. To the center of the bar 1-9 is connected a forked arm 20, having a vertical bar 21, pivoted between the forks. To the lower end of the bar 21 is pivoted a cross-bar 22, and a link 23 connects one end of the cross- To the cross-bar 6 are- -bar with one of the inner drag-bars 14, and a i link 24 connectsthe outer end of the crossbar with the other inner drag-bar. A swingletree 25 has a connection with the vertical bar 21. The outer ends of the eveners have a connection with the axle through the links 26 and 27 and support swingletrees 27 From the seat-support depends a bar 29. Between the bars of the seat-support is located and secured thereto a brace -bar 28, having a central opening. A rod 30 has a pivotal connection at the end 31 with the brace-bar 28 and at its other end with the bar 29 and has a central portion 32, located below a line drawn between its ends.

To the rear end is connected a cross-bar 33,

at the ends of which are adjustably secured in their lengthwise direction and on a pivotal center in order that they may be adjusted to suit .the attendant. v

The dra -bars are connected by a bail (shown in etail at Figs. 3, 4,l and 5) and consist of two main sections 35 and 36, the latter provided with depending arms 39 and 40. The section 35 has a depressed center` portion 41. justable in connection with their main sections by the bolts 74 inorder that the distance between the two arms of 'a section may be -varied. A lever 42 has a pivotal connection with both sections at the points 43, and centrallybetween thesepoints is formed anopening 44. This opening receives the portion 32 of the rod 30, as shown at Fig. 2. v A thumblatch 45 has a pivotal connection with1the le- The arms 37 and 40 are made ad- IOO rant 46 has a connection with the section 36 of the bail and with which the thumb-latch makes a connection. A spring holds the thumb-latch in engagement with the toothed quadrant; The arms of the sections of the bail pass through loops 48, connected to the drag-bars, thereby forming a connection be'- tween all the drag-bars. The outer arms of each section of the bars are suspended from the beam 1 of the main frame by the links 49, which hold the sections of the bail in alinement, so that all parts will move together.

By reason of the foot-lever having a connection with the bail and as the two sections of the bail are locked together the attendant can move the bail transversely of the main frame, thereby moving the drag-bars on their pivotal centers and swing them back and forth while cultivating the corn, and all four drag-bars move to ether. By means of the lever 42 and toothe quadrant 46 the two sections of the bail can be adjusted with res ect to each other, which will move the two ag-bars for a row of corn toward or from the center of the row in order that the shovels for a row of corn will always be centrally of the row and when adjusted may be so secured, and this adjustment does not interfere with the operation of the foot-lever 34. By suspending the bail by the links 49 and the center connection the drag-bars can be raised and lowered independentl of the bail. The toothed quadrant 46 and ever 42 by reason of the ho es 75 can be ad 'usted therewith so as to move the-bars 38 an 39 toward and from the center of the row when the bars 37 and 40 are adjusted, which will locate the shovels of a row the same distance from the center of the row. To the rear end of each of the poles 4 and 5 is secured the lifting-lever arrangement for the drag-bars, and as such arrangement is the same for each pair of dra -bars a descripjecting beyond the bracket.

tion for one pair will be su cient. To the upper-face of the pole 4 is secured' a bracket 50, supporting a shaft 51, having its ends pro- To the inner projecting end of the shaft is ixedly secured l a toothed quadrant 52, having a forwardlyextending projection 53, which comes in contact with a set-screw 54, supported by the bracket 50, and limits the forward movement of the toothed quadrant. A hand-lever 55 has a pivotal connection with the toothed quadrant 52 and has the usual dog engagement with the toothed quadrant. A hook 56 has a connection with the hand-lever and has a connection by the rod 57 with one of the inner drag-bars.

An arm 58 has a pivotal connection with the toothed quadrant 52 in rear. of the pivotsupport of the qliadrant and extends forward therefrom, to t e free end of which is connected a spring 59, the. other end of which has a connection with the main frame of the cultivator. The action of this spring is to hold the quadrant 'a'.g'gainst"1 theset-screw 54. To the arm 58 is adjustably connected a block 60, having its lower edge formed'in steps. By means of the hand-lever 55 the `quadrant may be rocked downward, which will raise the drag-bar connected therewith until the block -60 comes in contact with the stop 61. By adjusting the block 60 along the arm 58 any one of the steps thereof ma be brought to engage the stop, which will vary the movement of the quadrant. B means of the dog connection with the quadyrant the drag-bar can be adjusted to the proper working de th.

To the outer en of the shaft 51 is secured a collar 62, having an inward projection 63, and between the collar and the bracket 50 is located a toothed quadrant 64, having a forwardly-extending projection 65, which engages the projection 63 of the collar, thereby imiting the forward movement of theiquadrant. A hand-lever 66 has a pivotal connection with the toothed quadrant and has the usual dog connection with the teeth of the uadrant. A hook 67 has la connection with t e hand-lever and has a connection with one of the outer dra ,-bars by the link 68. By means of the han -lever 66 the toothed quadrant 64 can be rocked on its shaft-support, which will raise the outer drag-bar, and by means of the dog connection therewith the drag-bar can be adjusted to place the shovels in t e proper working position. As the collar 62 lhas aconnection with the shaft 51 and as the shaft has a connection with the' toothed'quadrant 52, it will be evident that as the quadrant 52 is rocked the quadrant 64 will be rocked with it, thereby raising both drag-bars by the one hand-lever, but permitting the outer drag-bar to be raised independently of the inner drag-bar. As the spring 59 exerts its influence through the quadrant 52 to the quadrant 64 below the center of the quadrants, its action will be to assist in raising lthe drag-bar when. both are raised by the hand-lever 55. It will be no- IIC two sections joined by a yoke to which the hand-lever is connected the connection of the hand-lever with the sections is facilitated; otherwise it would be necessary to thread the shaft, it being a single piece, through a pollar having a connection with the handever.
