SULKY PLOW.

SPECIFICATION- forming part of Letters Patent No. 306,342, dated October 7, 188%.

Application filed January 2, 188 4. (No model.)

To all whom, it may concern Be it known that we, EDMUND D. I\.'IEAGHER and CALEB E. Townn, of South Bend, in the county of St. Joseph and State of Indiana, have invented a new and useful Improvement in Sulky-Plows; and we dohereby declare that the following is a full, clear, and exact description of thesame.

Our invention consists in the devices and 1c combinations of devices, as hereinafter described, which go to make up our improved plow, whereby the plow is rendered simple in its construction and efficient in its operation.

I 5 In the accompanying drawings,whieh illustrate the special embodiments of our invention, Figure 1 is a side elevation of the sulkyframe, the position of the wheels being shown by dotted lines. Fig. 2 is a plan viewof the .20 sulky-frame and plow. Figs. 3, 4., and 5 rep resent details enlarged. Fig. 6 is a rear view of the plow and sulky. Fig. '7 is a detail view.

In these drawings we have represented a form of plow such as that shown in Letters Patent granted E. D. Meagher, February 7, 1882, and numbered 253,403, but any other style of plow may be used with our invention. The frame of the sulky is mounted upon a 0 pair of wheels, one of which is capable of adjustment and runs upon the land in the ordinary manner.

The particular construction of the frame is described hereinafter. The plow'beam A is provided with. a suitable clevis, and is drawn by the team in the ordinary manner. The point of connection of the su1ky-frame to the beam A is at the point 1. The connection here shown consists of a bail, 13,

40 which has a straight part, I), and arms 21 and 31.. We prefer to make the straight part and arm 21 of this bail of round iron red, the other arm, 31, being of malleable iron. The bailis hinged in suitable sockets in the 5 end castings of the sulky-frame. The horizontal part b is held to the plow-beam by means of a turning-plate, G. This plate has lugs2 2, which are adapted to pass through openings 3 3 in the flange 4c of a fixed plate,

D, on the plow-beam, and to project under the said flange when the plate 0 is turned on the plate D. The upper part of the plate 0 i has a tubular bearing for the bail. The tube is cutaway in the central part to form a re cess for a sleeve, 5, which may be held to the bail by a set-screw, and thus hold said. plate against lateral movement. The bait turns at all times freely in this tubular bearing. The plate 0 slides freely on the bail when not held by the set-screw, and the flange of the plate D being circular, the upper plate may turn on the lower. From this construction it will appear that the plow-beam may be turned in a horizontal plane on the upper plate as a pivot, or it may be turned in a vertical plane 011 the bail as a pivot, or maybe movedlaterally on the bail. It is held rigidly only against tipping from side to side. This bail forms the connection between the plow and sulky, by means of which the sulky is moved with the plow, the bail serving to push. the sulky, and as it is inclined forward it permits the sulky-frame to rise or fallwithout interfering with the movement of the plow. Further, as the point of connection with the plow-beam is in rear of the frame and well back upon the beam, the plow may be swung from side to side without afiecting the sulky, and the beam may also be tipped readily to give greater or lessdepth of cut. The plate D is connected to the beam conveniently by means of two cheek-pieces,6 6, and abolt, 7,passing through them and the beam.

lVe have made provision also for another movement in the connection between plow and 8 5 sulky. In case the plow strikes an obstruction, it is desirable that the shock should not be communicated to the sulky. For the prevention of this, one of the plates, preferably the upper plate, O, is slotted lengthwise of 0 the beam, and receives a low stud, S, which limits the front and rear movement of the plate 0 upon the plate I) sufficiently to keep them in working position in relation to each other at all times. Ordinarily, when the plow 5 is in motion, the stud S willbe in the front end of the slot, and will be the bearing-point at which the plow will push upon the bail to move the sulky; but should the plow be suddenly arrested by striking an obstruction, the

snlky will have movement to the length of the slot, and will to that extent be relieved of the V shock;

For economy of material, and to avoid increase in the number of parts, a seat is formed in one of the cheek-pieces 6, for the reception of the end of the weed-turning arm 13. The seat is formed by means of two vertical ribs, 8 s, between which lies the end of the rod formed with a loop, '6. The bolt which holds the eheekpieces passes through theloop, and the nut on the bolt bears on the loop, and thus holds the rod without further fastening.

In order not to interfere with the lateral movements permitted by the connection above described, and at the same time to provide means for putting the plow into or out of ground, we have devised an improved mech anism for this purpose. It consists of a lifting-bail, E, pivoted to the sulky-frame, having a sliding connection with the plow-beam. This sliding connection is formed by passing the bail across (preferably underneath) the plow-beam, and limiting its movement by means of an elongated staple, e, on the beam.

One arm of the bail E is connected by the rod f to a lever, F, pivoted on the end piece of the frame, and moving over a segment, 9. The handle of the lever is within reach of the driver, and he may, by moving the lever, lift or drop the beam and lock it in any position,

the bail sliding on the beam as thelatter rises or falls.

It will be seen from an inspection of Fig. 6 that the distance between the sulky-frame and the plow-beam may be fully changed. If the said frame be liftedas by the wheel passing over a stonethe connecting-bail will simply be swung backward and the lifting-bail will be drawn back. by the wheel falling into a hollow-will only bend down and spread out the bails by pushing the lifting-bail forward. The same con nection of the lifting-bail to the beam permits the beam to swing from side to side on the rear pivotal connection.

Ve are aware that the bails may be modified in form'without departing from the spirit of our inventionthat is to say, with the retention of the flexible connection, allowing the free up-and-down movement of the sulky, not interfering with other necessary movements of the plow; or, retaining the rear rigid connection in the form of a bail or link, we may use other forms of flexible lifting devices than that shown.

The sulky-frame is composed of end pieces and two bent bars bolted thereto. Each of these end pieces may be of a single casting. As shown in the drawings, on the land side is an end piece, F, in which is the bearing of a crank, G, provided with a journal, m, for the land-wheel and' bearing-socket for the ends. A lever, f, with the usual locking device, serves to'move and to retain the crank and wheel in place. On the other side of the frame is a lower casting, 71, having the jour- Depression of the sulky-as nal-arm k of the furrow-wheel attached to it, and an upper casting, II, in which are the bearing-sockets of the bail ends and lever, and which has also a segment-rack. for the lever. These castings are connected by means of bent bars N N. These are of ordinary rolled iron or steel, and may be swaged or bent into shape by any well-known means. They are bolted to the end castings by bolts 0. The tongue is attached to the bars N N, as shown in Figs. 1 and 7, and the seat may be connected to and rest upon the same bars.

The special shape shown of the end pieces is not material. The bars are set on edge, and are inclined to front and rear, as shown. In operation the plow has the capacityto adj ust.itself to the work, and free movement, as explained. It is regulated as to the width of the furrow-slice by the set of the clevis in the ordinary way. It may be adj usted in proper position on the crank, in proper rela tion to the sulky, by simplyloosening the setscrew in the sleeve and then starting the team. The draft brings the plow into proper position, and then the screw maybe set again. In driving to and from field the front end of the beam may be raised by the lifting-loop, which throws the weight of the plowon the land side wheel.

lVe claim as our invention- 1. In a sulky-plow, a bail, 13, forming pivotal connections between the plow-beam and sulky-frame, adapted to permit separate vertical movement of either, and a lifting-bail pivoted 011 the sulky-frame, having a longi tudinally-sliding connection with the plowbeam in front, a locking-lever, and a rod connectin g it to the lifting-bail, whereby the plowbeam is held up to any given point and the movement of the sulky prevented from affecting the plow, substantially as described.

2. In "asulky-plow, a bail connecting the plow-beam at a point in rear of the sulkyframe and permitting free vertical movement, connection between said bail and plow-beam, whereby lateral movement is permitted to the plow. on said bail, a lifting-bail pivoted 011 the sulky-frame, and having longitudinally and laterally sliding connection with the beam in front of the sulky-frame, a locking-lever, and connection between said lever and the lifting-bail, substantially as described.

3. In a sulky-plow, a pivoted bail forming connection between the sulky-frame and the gitudinally and laterally sliding connections with said beam, and connections to. a lockinglever, whereby the plow is permitted free movement independent of the frame, substantially as described.

4. In a sulky-plow, the bail B, connecting the plow-beam at a point in rear of the snlkyframe, whereby a vertieallydlexible connection is provided, and means, substantially as described, by which said connections have a limited forward and backward sliding movement and a lateral movement, substantially as described.

5. In combination with the frame and beam of a sulky-plow, a bail, 13, connected to the frame and pivoted to the beam in rear of the sulky-frame by longitudinally and laterally adjustable connection, and a lifting'bail in front attached to the beam by a longitudinally sliding connection, substantially as described.
