SPECIFICATION forming part of Lettcrs Patent No. 292,877, dated February 5, 1884.

' Application filed May 28,1583. (No model.)

To all whom, it may concern:

Be it known that I, FRANK '1. VERIIAREN, residing at Spencer, in the county of Clay and State of Iowa, and a citizen of the United States, have invented new and useful Improvements'in Cultivators, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a top or plan view, showing the arch, draft-bars, guide-rod, wheel-spindles, and beam-coupling of a tongueless cultivator. with the drag-bar and its actuating device and the arms for hanging up the beams; Fig. 2, a side elevationof the parts shown in Fig. 1, showing in dotted lines the position of the wheel; Fig, 3, a detail of the devices for raising and lowering the drag-bar; Fig. 4, a detail, being a rear elevation of one side with the pipe-box partly in section.

Itis customaryto use what are termed dragbars or runners with cultivators, for the purpose of furnishing a support for the beams and removing the strain from the beam-coupling and the wheel-spindle in moving the cultivator from place 'to place, with the plowbeams elevated. Heretofore such drag-bars have been applied by being removably attached, so as to be taken off and placed in position to rest on the ground when the beams are elevated, or in position to lie above the ground when the beams are in use, and they have been pivoted so as to be raised or lowered, as required, to be out of use or in use; but in every case this raising and lowering of the drag-bar has to be performed by the operator, who makes the changes as he requires the drag-bars to be acting or non-acting.

The main object of this invention is to ap- I ply drag-bars to a cultivator and have them broughtinto position for use as the beams are elevated, or thrown up out of use as the beams are lowered, and have both movements performed automatically by the act of elevating or lowering the beams; and its nature consistsin the devices and combinations hereinafter described, and pointed out in the claims, for accomplishing the object stated;

In the drawings, A represents an arch or frame, having an upper or horizontal portion, a, side or vertical portions, a, and lower horidle or bearing a of the arch or frame,and

forming the horizontal pivot to allow of vertical movement of the beam.

0 are clasps or. coupling-boxes, one located on each pipe-box B, and each having a rearwardly-projectiug flange or portion, 0, for the attachment of the forward end of the plowbeam, by passing a pin or bolt through the coupling on the end of the beam and a hole in the flange 0, and by having also ears or lugs c at the front side, through which a tightening-bolt, 0, passes, for drawing the parts of the clasp or boxingfirmlydown upon the pipebox, so i as to be immovable thereon. This clasp or box may be of the form shown and described, or of any other of the well-known forms for attachment of the forward end of the beam to the pipe-box, and the beams are adjusted in or out by unloosening the bolt 0 and slipping G on the pipe-box until the de sired position is reached, and "then securing it by the tightening-bolt c.

D are heads or supports, one secured in any firm manner to each end of the spindles a. Each head or support has a rearwardlyextending arm, (I, and is provided on its outer face with 'projecting ears (1, in the form of construction shown.

E represents the drag-bars, each having at its lower end a flat portion, (2, standing at the proper inclination to themain portion to rest flat, or nearly so, on the ground, when the beam is lifted. The upper end of each dragbar is turned at right angles, or nearly so, to the main or body portion, to form a short arm, a. This short arm 6 has pivoted thereto one end of a link, 0, the other end of which is pivoted to the end of the arm I), projecting out from the pipebox B, and the upper end of the drag-bar is pivotally connected to the end of the arm (I of the head or support D.

F are arms or supports pivoted at or near their forward ends, one to each of the vertical portions of the arch or frame, by a pin or pivot, f. The forward end of each arm or support F has pivoted thcretothe upper end of a link, f, the lower end of which is pivoted to the end of an arm, 0, projecting out from the pipe-box B.

G is a guide rod or bar, having an upper horizontalportion, 9, side or vertical portions, 9, and lower horizontal portions, the ends of which have a downward turn.

H represents the draft-plates, one on each side of the cultivator, and each pivoted at its inner end between the ears (1, by a pin or pivot, h, and each having an eye or socket plate, h, to receive the downward-pro ecting ends of g and form a connection between the two plates, by which they will be moved in unison.

I are wheel-spindles, one secured to the inner end of each draft-plate H, and projecting out therefrom to receive the wheel.

It will be noticed that the coupling or pipe box B is connected by the link 0 with the arm c of the drag-bar E, which drag-bar is pivoted to the end of the arm (Z at its upper end, so that it will remain in a stationary position at such upper end. The result of this construction is that any movem cnt communicated to the pipe-box by the vertical movements of the plow-beam will be communicated through the arm b, link 0, and arm 0 to the drag-bar, and the arm I), link 0, and arm 6 are in such relation to each other and to the boxing O and the plow-beam that an upward movement of the plow-beam raises the arm I), throwing down the arm 6, and with it the drag-bar, while the downward movement of the plowbeam throws the arm b down and raises the arm 6 and with it the drag-bar. 7

It will also be noticed that any movement of the pipe-box B by the raising or lowering of the plow beam will be communicated through the arm I) and link f to the arm or support F, and this arm I) and link f are arranged in such relation to the plow-beam and the arm or support F that an upward vertical movement of the plow-beam throws the arm or support F down in position to hang the plow-beam thereon, while the downward vertical movement of the plow-beam throws the arm F up where it will be out of the way.

The plow-beam is to be provided with a hook, by means of which it can be hooked over or 'onto the arm or support F and beheld in this suspended position. V

The devices for throwing the drag-bar down as the beam is elevated and raising it as the beam is brought down in position for use can be varied somewhat from the form and an rangement shown, so long as they will act to give the required movements to the drag-bar from the movements of the plow-beam, and it is not necessary for the operation of the dragbar that the arm or support F should be movable also, as this arm or support might be staproduces a contrary movement for the dragbar, so that it will be' brought into use or thrown out of use as the beam is elevated or lowered.

What I claim as new, and desireto secure by Letters Patent, is as follows:

1. A drag-bar or runner and a connection therefor with a plow-beam, by which move ments of the plow-bcam vertically will produce a reverse movement to the drag-bar, substantially as and for the purposes specified.

2. A drag-bar, E, pivoted at its upper end and provided with an arm, e, in combination with a link, 0, and arm I), actuated by the movements of the plow-beam for raising andlowering the drag-bar, substantially as specified.

3. A drag-bar, E, pivoted at its upper end and provided with an arm, 0, in combination with the link 6, arm b, pipe-box B, and a plow-beam attached to the pipe-boX, for automatically raising and lowering the dragbar, substantially as specified.

4. An arm or support, F, and a connection with a plow-beam and devices connecting the beam with the arm or support, for automaticall y operating the arm or support as the beam is raised or lowered, substantially as and for the purpose specified.

5. An arm or support, F, link f, and arm I), operated from the plowbeam-, for automatically raising and lowering the arm or support F, substantially as and for the pur poses specified.

6. An arm or support, F, and link f, in combination with the arm I) and pipe-box B, having a plow-beam attached thereto, for automatically operating the arm or support by the movements of the plow-beam, substantially as and for the purposes specified.

7. An arm or support, F, link f, arm I), pipe-box B, arm I), link 6, arm 6, and dragbar E, in combination with a plow-beam attached tothe pipe-box, for automatically operating the arm or support and the drag-bar by the movements of the plow'beam, substantially as and for the purposes specified.
