GRADING AND DITCHING MACHINE.

SPECIFICATION forming part of Letters Ijatent No. 397,841, dated February 12, 1889.

Application filed June 11, 1888. Serial No. 276,746. (No model.)

To all wlwm'izfi may concern.-

Be it known that I, GEORGE E. DURKEE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Grading and Ditching Machines, of which the following is a specification.

In a grading and ditching machine characterized by my improvement the plow-beam is suspended byordinary cords or chains, which can be drawn up or let down, so as to raise the plow-beam'at either end or raise or lower both ends of the plow-beam simultaneously. It has heretofore'been proposed to attach one suspending-chain to the plow-beam in advance of the plow, and to attach. another suspending-chain to the plow-beam in the rear of the plow, and to provide for such two chains two separately-arranged elevated winding-shafts, each provided with and operated by its own hand-wheel. This has necessitated the arrangement of one winding-shaft at right angles to the other and the frequent transferm ent of the attention of an attendant from one handwheel to the other, whereby difficulty arises in operating both hand-wheels simultaneously to raise or lower both ends of the plow-beam syi'ichronously. Some further difficulty has also been experienced under said arrangement, since the points from which the chains are suspended were not both over the plowbeam,and hence one chain tended to draw the plowbeam toward the body-frame. To obviate such. obj cot-ions, I-provide a couple of winding-shafts, which can be readily connected or disconnected, at the will of an attendant, and I further provide a single handwheel, of which the winding-shafts can either be alternately or simultaneously opera-ted. I also arrange one of said winding-shafts in alignment with the other, whereby the line of shat'ting comprises two separate rotary windin g-shafts arranged parallel with and over the plow-beam, thereby bringing over the plowbeam the points from which both of the suspending-chains are hung.

A further object of my invention is to provide an improvement in the mode of connecting a draft-bar with the plow-beam, as hereinafter setforth.

A further object of my invention is to dispense with an arrangement or rear-controlling-bar (shown attached to the plow-beamin the rear of the plow in Patent No. 275,614, heretofore granted to W. J. Edwards and myself,) and to provide means for permitting easier movement on the part of the plow and a greater reliability in guiding the same, as hereinafter more particularly described.

In the accompanying drawings, Figure 1 represents in side elevation a grading and ditching machine embodying my invention, the side represented being the plow side of the machine. In said View the rear wheel at the said plow side of the machine is omitted for convenience of illustration. Fig. l represents a bracket by which one end of the draft-bar can be supported. Fig. 2 is a view similar to Fig. 1, but shows in elevation the delivery or opposite side of the machine. In this View the swinging extension portion of the elevator is removed for convenienceof,

illustration. Fig. 3 is a top plan view with a portion of the machine that is above the horizontal sills of the body-frame removed. Fig. i represents in perspective, on a somewhat larger scale, certain devices for connecting the plow-beam in the rear of. the plow with the body-frame of the machine. Fig. 5 represents a section through the movable bearing E of Fig. 4, and serves to more clearly show the connection of the sliding pivot or pintle E with said bearing. Fig. 6 represents in part elevation a raising and lowering mechanism for the chains by which the plow-beam is suspended, the great-er portion of the winding-shaft B being, for convenience of illustration, broken away. Fig. 7 represents said raising and lowering mechanism in elevation, and shows the clutch in position to connect the winding-shaft B with the rotary shaft b whereas in Fig. 6 said clutch is in position to connect the shaft 12 with the winding-shaft B. Fig. 8 represents said raising and lowering mechanism in perspective. Fig. 9 represents a section taken transversely through the plow-beam b at a point convenient to show in elevation a portion of the draft bar D and connections be tween the draft-bar and the plow-beam. Fig. 10 represents a section taken through Fig. 9 on the line 1O 10. Fig. 11 is a sect-ion through too the bracket and a portion of the draft-bar on line 11', Fig. 10.

A indicates a suitably-constructed wheelsupport-ed bodyframe adapted to provide supports or bearings for various operative members of the grading and ditching machine.

The plow B is attached in any ordinary or suitable way to the plow-bcam b, which latter .is so suspended as to place the plow in position for plowing up the soil and delivering the same onto the elevating-conveyer c of an elevator, The plow-imam is suspended by a couple of ropes or chains, 1) and that are connected with the plow-beam respectively in advance of and to. the rear of the plow, whereby the plow-beam can be raised at either end or lifted bodily, so as to raise both ends simultaneously, accordin g to the way in which the chains are operated. As a means for permitting the ready and convenient operation of said suspendingchains either alternately or simultaneously, at the will of an attendant standing upon the machine, the two chains are respectively attached to one and the other of a couple of rotary shafts, B and 13?, which can be either connected or disconnected by a clutch. In either case, however, the shafts may be and preferably are operated by a single hand wheel, B arranged within convenient reach of the attendant.

The horizontally-arranged rotary shaft B, whereon the chain 1) may be wound, is arranged substantially over and parallel with theplow-beam, and is supported at;- a suitable height above the same by means of standards (l and a, which rise from and are secured to the body-frame.

The winding-shaftB at its rear arranged to extend part way through the bore of ahub or collar, b which is secured to the said shaft and arranged; to turn in a suitable bearing upon one of the standards, as best shown in Fig. 6. In the rear of and preferably in alignment with the winding-shaft B. is a shaft, Z1 which is both rotatiye andlongitudinally movable. The shaft 6 carries at its rear end a hand-wheel, B and at; its forward end has a bearing in the hub or collar, I), wherein it may both turn and slide independently of the said collar, and hence independently of the winding-shaft B, with which latter, however, it can be connected by a clutch, so that the winding-shaft can be operated by turning the handavhcel. The winding-shaft 13 is made hollow and arranged as a sleeve upon the shaft U, which latter can be either moved endwise through or rotated independently of thehollow winding-shaft.

The hollow winding-shaf t 13 may be sup ported in any suitably-arranged bearings as, for example, in bearings which, like the bearing for the collar U, can be formed upon a cross --piece, a herein shownprovided with bearings a for the foregoing-mentioned purposes, and secured upon standards a and a that rise from the mainbody-frame.

The rotary and sliding shaft h is provided with a double clutch gland or clutch member, B", which can be adapted for engagement with the winding-shaft B and the hollow windingsha'ft- 1-3 in any suitable inechanical way. As herein shown, the double clutch member is simply a shouldered block secured upon the shaft b, and adapted to engage with either a. shouldered end portion of the collar 1) or with a like shouldered end portion of a collar, 1), which is secured upon the end of the rotary winding-shaft B that is opposite the shouldered end of the hub b, the engagement of the double clutch member with either one of said collars which constitute the clutch members being dependent upon the direction in which the shaft-b is shifted endwise. The width of the shoulders or engaging portions of the clutch members and the distanceapart of the collars Z) and b will be such that when the double clutch member occupies a position midway between said collars it will be in engagement with both, whereas by shifting it in either direction from its middle point it can be brought into engagement with but one of the collars orclutch members.

As a result of the foregoing-deseribed arrangemcnt of raising and lowering mechanism the plow-beam can be raised and lowered at either end, or it can be raised and lowered at both ends at one and the same time. Thus the attemlant by taking hold of the handwheel 1 3 can push the shaft: U forward to an extent to place the double clutch member thereon in engagement solely with the collar b that is fixed upon the forwardly-arrange(l rotary windingshaft B, so that by then turning the hand-wheel the two windingshafts that are thus temporarily connected to form in effect a single shaft can be turned so as to either wind or unwind the chain 1), and hence raise or lower the plow-beam from its forward end. In like manner the attendant can pull the shaft I)? back to an extent to place the double clutch member solely in engagement with the collar or the hollow winding-shaft 13?, so that by turning the hand-wheel said hollow shaft can be turned by operating the shaft h, with which it is held in engagement by the clutch. The winding-shaft B can therefore be operated separately from the forward winding'shaft section, B, so as to raise and lower the plow-beam from its rear end. On the other hand, however, by adjust ing the shaft b so as to bring the double clutch member B in its intermediate positioinboth winding-shafts will be in rigid connection, so as to permit the two chains to be sinuiltaneously wound or unwound, it bein understood that when the double clutch gland l3" occupies its intermediate position it may engage both the collar or clutch member if that fixed on the shaft B and the collar or clutch member that is fixed upon the winding-shaft B whereby the two shaft-sections If and B will be temporarily connected as, a single shaft through the medium of the clutch, which will likewise connect such shaft with the hollow windingshaft 13 The winding-shaft B can be temporarily locked against rotation by a pawl, b arranged to engage a ratchet, If, on the hub or collar 11 that is secured to said shaft, while, on the other hand, the winding-shaft B can be conveniently locked against rotation by a pawl, 1), arranged to engage a ratchet, 1) upon said hollow windin -shaft. The pawl b is secured upon a rock-shaft, I), having a handle within convenient reach of the attendant, while the pawl b" can be simply pivoted to one of the bearings a, so as to place its handle within convenient reach of the said attendant.

The winding-chain b can be attached in any suitable way to the shaft B' as, for ex.- ample, it may be connected with a clip, I), secured upon said shaft.

To the plow-beam is attached a draft-bar, D, which is arranged laterally to the length of the plow-beam and connected therewith at a point in advance of the plow. This draftbar can be connected with either the forward axle or forward bolster or rear end of a tongue by a rod or chain attached at its rear end to the draft-bar, as at (7, Fig. 3, and at its forward end connected with said axle or bolster or tongue of the machine in any suit-able manner. The draft-bar is at one end pivoted in or upon any ordinary or suitable bracket, I), that is secured to the main body-frame, while at its opposite end the draft-bar is connected with the plow-beam by a pivotal connection. (Shown in Figs. 9,10, and 11.) In said figures a bracket, I), is secured to the plow-beam so as to'depend therefrom, and is at a point below the plow-beam provided with a horizontally-arranged slot, (1, adapted to receive the draft-bar and made somewhat longer than the width of said bar. At a point midway of the length of the lower edge of said slot the bracket is provided with a stud, (1 which engages in a corresponding recess in a plate, (1 that is secured to the underside of the draftbar, thereby providing a knuckle-joint.

The draft-bar D is also connected with the plow-beam at a point in advance of the plow by an extensible arm, D that is hinged to the plow-beam, so as to permit the latter to be shifted. endwise. To such end the arm is divided into two parts, one part, (1", being secured to the draft bar and the other part, d, being attached to the plow-beam by a hinge, (1, having a vertically-arranged pintle. ()ne part of the arm is provided with a slot, (F, for a set-screw or a bolt, (Z secured to the other part of the arm and provided with a nut, (7- In this way the arm can be adjusted in length after the nut has been loosened, after which the two parts of the arm can be held rigidly together by tightening up the nut. By adj ustin the length of this two-part arm I) the plow-beam can be tilted laterally, it being sometimes desirable to effect such tilt-as, for instance, to set the plow for cutting sod.

The hinge d and the stud or pivot (V, which is directly below the hinge, permit the plowbeam to be shifted endwise, and the said stud (Z is desirably rounded at its upper end, so as to permit the aforesaid lateral tilt on thepart of the plow-beam and plow.

The draft-bar serves to guide and control the plow-beam in advance of the plow, while at a point in the rear of the plow I provide certain devices, hereinafter described, adapted not only to control and automatically guide the plow-beam, but also to adjust the same, so as to bring the plow nearer to or farther from the receivin end of the elevator.

IVith reference to said devices, which are best illustrated in Figs. 4 and 5, E indicates a staple-shaped rod which is secured to the plow-beam at a point back of theplow, as in Fig. 3, the eit'ect of such arrangement being simply a horizontal rod or pintle, 6, arranged alongside of and parallel with the beam, and provided at its ends or at other suitable points with stops or shoulders e. Said pintle e is engaged by the eye 8 of a pivot or eyebolt, E, which serves to provide, in conjunction with the pintle c, ahinge-connection between the plow-beam and a block or bearing, E wherein said pintle has its bearing. This arran gement of hinge construction between the plow-beam and the block E that is understood to be supported from and arranged alongside of the body frame, permits the plow-beam to be shifted endwise, so as to set the plow with referenceto the elevator, and also permits the pintle e to turn in said eye e of the pivot when the plow is tilted laterally.

In order to permit the rear portion of ihe plow-beam to have a certain latitude of side movement, whereby the plow may dodge obstruct-ions, the eyebolt or pivot E has a sliding connection with the block or bearing E and is subject to a spring, a To such end the eyebolt passes through an opening in the block W, and is at one end provided with an adjustable nut, c", between which and the said block is arranged. the spring 6". This spring serves to maintain the plow in proper working order, but yields sufficiently to allow the plow to dodge obstructions.

The block. E is desirably fitted to slide along one or more, but preferably a couple, of vertically-arranged guide-bars, E whereby the plow may be raised and lowered by the chains hereinbefore described, it being in this connection observed that the pivot or eyebolt E can turn about its axis, so as to adapt the hinge to the raising and lowering of either end of the plow-beam.

The upright guide-bars l l are at their upper and lower ends adjustal'ily attached to horizontally-arm nged brackets E, that are in turn secured to the standard a on the main body-frame. Each bracket is provided with a horizontal slot, 6", for an end of one of the guide-bars, which can be held at any desired along its bearing 1) by changing such pin, from one to the other of the holes in the draft 4 bar. :3 y the foregoing arrangement the plowbeam is in effect connected with the bodyframe by a sliding universal joint, which allows all of such movements as it may be desirable to permit on the part of the plowbeam.

In order to prevent stalks or trash from be ing taken. up by one of the rear wheels and carried forward to the hinge-jointin the rear of the plow, the body-frame is at one corner provided with a scraper, F, for freeing the rear wheel at said corner of the machine from t ash. In like manner thebody-frame can at its opposite rear corner be provided with a scraper, F.
