To all whom it may concern:

Be it known that I, CHARLES T. RAY, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain ed to exemplify the invention: it being understood that changes in the details may be made without departing from the spirit of the invention, or the scope of the subjoined claims. v

Fig. 8 is a detail view of the crank 66 I which forms a member of the means for adjusting the forward furrow turning-member, showing therein the trunnioned bearing for the connecting rod 65.

Fig. 9 is. a rear end elevation of the implement.

The main frame is provided with a straight side member 10 which extends from the front to the rear end of the frame. Its other members may be variousl arranged to produce a frame which is wider at the rear than at the front. The frame herein exemplified comprises a longitudinal member 11 arranged at the side opposite the member 10 and extending substantially parallel with the latter for. a part of its length and thence extending diagonally toward the front end of the member 10 as shown at 13. The rear ends of the members 10 and 11 are connected with each other by a transverse member 12. 14 designates a third longitudinal member. This is arranged between the members 10 and 11 and substantially parallel with the member 10. Its rear end is suitably secured to the rear transverse member 12. These members preferably are formed of channel irons. The front ends of the

members

10, 13 and 14 are secured to a uniting member 15, which extends for- Wardly and also upwardly therefrom. This member is preferably a strong casting having horizontal flanges 15, upon which the frame members 1O, 13 and 14 respectively rest, and vertical webs 15 against which said members respectively lie, suitable means being employed to secure the contacting parts of the members together. The uniting at the front end with a sleeve 15 surmounted by a plate 15 A designates a large traction wheel of suitable construction, which is arranged between the

members

10 and 14 and at or about the longitudinal center of the implement. Tminediately in advance of this traction wheel there is a forward furrow turning member B of any suitable kind, the one herein shown being an ordinary single moldlboard plow. This forms a furrow on the bottom of which the action wheel runs. At one side of the frame there is arranged a suitable wheel C which travels upon the unplowed land and is suitably mounted to be vertically adjustable in accord with the depth of the furrow in which the traction wheel runs, any of the usual or suitable means for such adjustment being employed.

At the front end of the implement there is a guide wheel D. This guide wheel is offset from the line of the forward furrow forming member and traction wheel A and traverses a furrow, made on the previous travel of the implement by a rear furrow forming member E which is disposed at the rear of the traction wheel on the side of the line of the traction wheel and furrow forming member B opposite that of the guide wheel.

The traction wheel is a large one and receives motion from an engine ofsuitable type which is geared thereto and is carried by the frame of the implement. The engine is illustrated diagrammatically at F and is shown as being mounted on a bed plate 19 supported by the members 11 and 1%. The engine employed is preferably of the gasoline type and in such case, a suitable radiator, clutch etc, not necessary herein more particularly to set forth, will be provided in practice Any suitable means for transmitting the power of the engine to the traction wheel may be employed, one such being herein exemplified. The means herein shown comprises a spur gear 20 which is suitably secured to the wheel A and has its teeth engaged by a pinion 22 mounted on a transverse shaft 23 which carries a gear 24. which meshes with a gear 25 mounted on the engine shaft 26.

The points or cutting edges of the front and back furrow forming members B and E are at the same level, and the lower surfaces of the guide wheel D and traction wheel A run upon the bottom of the furrows made by said members; As already stated, the traction wheel traverses a furrow made in the same travel of the implement by the furrow forming members immediately in front of it, while the guide wheel is arranged in advance but to one side of the line of the front furrow forming member and traverses the furrow made on the previous travel of inane-ca coming any tendency for the frame to tilt the implement by the rear furrow fox-min member, as clearly shown in Fig. 1. A fur row wall is thus presented against whic the guide wheel may bear and which may b used as a guide in the manual guidance 0 the implement. A further important ad} vantage results from the use of furrow forming members and wheels arranged in the lines herein set forth, as forces are thereby brought into operation which overcome an objectionable extent of side draft which would tend to unnecessarily strongly press the guide wheel against the solid wall at one side of the furrow or the loose dirt at the other side of the furrow, such as occurs when furrow forming member or members arranged only at the front or only at the rear of the traction wheel, are employed. This unnecessary side draft introduces an unnecessary amount of friction for the engine to overcome.

Moreover, the employment of furrow forming members arranged as herein shown, reduces the number of travels of the implement required in plowing a field: the setting of the furrow forming member so that its point or cutting edge is level with the bottom of the traction wheel produces a furrow with a smooth even bottom by overforward or back, which tendency, unless corrected, would produce an uneven furrow: and these smooth even bottoms provide most desirable bases for the traction wheel and guide wheelto traverse. When single moldboard furrow forming members, such as herein exemplified, are employed, they are set out of line with each other a distance equal to the width of the furrow which each is to make, as shown in Fig. 2, thus giving sufiicient side draft to hold'the inner edge of the guide wheel against the solid Wall of the previously formed furrow with strength suiiicient for the purpose intended to be secured. but with no undue force, that is, with no force unnecessary in proper plowing. The forward furrow forming member is arranged so that it will plow a stri one side of which is substantially in line with the outer side of the traction wheel and th other side of which is in line with the inner side of said wheel, whilethe rear furrow forming member is arranged to plow a strip commencing substantially in line with the inner side of the traction wheel.

The guide wheel D is connected with means whereby the implement may be guided manually, preferably from a seat 27 at the rear of the implement. This seat 27 is mounted on the upper end of a seatcarrier 28, so arranged that the seat is disposed substantially in line with the straight side member 10 of the frame admenace jacent to the line of which member the guide wheel D and the forward forming member B are arranged. Accordingly, the operator has an unobstructed view of said guide wheel and furrow forming member and is thereby enabled to better guide the implement in a straight path. The wheel D is journaled in the lower end of a yoke 30 which is provided with a vertical pivot 31 mounted in the sleeve 15 at the front end of the casting 15. The mechanism by which this wheel is turned by the operator to guide the implement preferably comprises a gear 32 which isvfixed to the-pivot 31 above the plate 15. This gear is engaged by a worm 33 mounted on a. shaft 3 1 from which an operating rod 35 extends rearward, the rear end of the operating rod having suitable means, as a handwheel 86, arranged convenient, to the operator on the seat 27. When the rod 35 is turned by the hand wheel, motion will be cOmmunicated to the pivot 31 through the shaft 34, worm 33, and gear 32. Conversion of the wheel D from a man-operated wheel to a casteringwheel constitutes one of the im-' portant features of the present invention. When the particular guiding mechanism herein set forth is employed, the worm 33 and its shaft 3st are preferablycarried by a cap 37 which serves also to house the gear 32 and is' mounted for lateral adjustment bodily on the plate 15 this lateral adjustment being such as to carry the worm out of or into mesh with the gear 32. The cap is guided in its movements, preferably by bolts or pins 38 which extend through openings 39, as shown in Fig. 3. The

niove'ments or adjustments of the cap are eiected by means which may be operated fromthe seat 27. This means, in the herein-exemplified form of the invention. com pris'es an operating lever 40 which is pivoted at 41 and is provided with a rod 4'2 whose forward end is connected-roan arm or crank 13 having a cam 15, the crank and cam being loosely mounted, preferably in the reduced upper end 44 of the pivot 31. The cam is arranged in an opening 46 formed in the cap 37. The correlation of the parts is such that the cam 15 engages the walls of the opening '46 and when turned, by the forward or rearwardmovement of the rod 42, operates to shift the cap 37 to one side or the other according to the direction of the turning move? ment given the cam. it being neted that in the herein exemplified form of the invention the opening 46 is approximately rectangular and that the cam 45 engages angularly-disposed walls thereof, whereby the cap is, shifted with a minimum extent of movement of the rod 4:2 and lever 40. Suitable provision for locking the lever and hence the cap, in adjusted osition, are provided: the means herein exemplified comprising a-latch, indicated at 4-7 in Fig. 9, the said latch being connected with a hand piece 48 (Fig. 6) and being arranged to engage any one of the teeth 49 of a segment 50. It is. only necessary that there be two teeth 49 in the-segment, .as there are only two positions to which the cap need be adjusted.

the'wheel C as an axis, the power being applied to the traction wheel. It will be observed tlrat the lower end of the yoke 30 is inclined rearwarchso that the center of the wheel D is out of line with the pivot 31, to facilitate the metering operation of the wheel. The locking of the land wheel C may be accomplished by any suitable braking means operable from a point within convenient reach of the operator on the seat "27. As the particular means for the purpose is not essential to the invention 1 do not consider it to be necessary to enter into any detailed explanation, but the mechanism herein described comprises, speaking generally, a transverse shaft 51 suspended in suitable bearings provided on the frame and having a down-turned cranked end 52 near the seat.

The wheel (1 is provided with a drum 53, and

suitable brake shoes, shown at 54, are arranged to engage the drum :by appropriate movement of the shaft 51, the shaft 51 being connected with the brake shoes by means which includes a rod 55 and suitable connections between the rod and the shoes.

The furrow forming members are independently adjustable relatively to the frame Further, the adjusting means devised by me and shown in the accompanying drawings is of such nature that the furrow-tunung members may be set to work at a. predetern'iined depth prior to the commencement of the plowing operation and when in operation will beyieldably supported in order that they may ride over'any obstru-ctions and adjust themselves when depressions or soft spots are reached. Mechanisms having the characteristics herein set forth and which, at the same time, are of most simple and practicable construction will now be described.

Each furrow turning -member B and E is provided with a vertical standard 60 which is mounted for vertical movement within a suitable guiding frame 61 carried by the frame. Each guiding frame preferably has friction-reducing rollers 62 engaging the forward and rear edges of the standard which passes through the frame. The forward furrow turning member B is operated by a lever 63 which is pivoted at 61 to an appropriate part of the frame and is arranged adj scent to the seat 27, the lower end ofthe lever being connected by a rod 65 with a crank 66 projecting from a shaft 67 having a second crank 68 extending rearward therefrom (shown in dotted lines in Fig. 6), the second crank having its rear end connected to a link 69 from the upper end of which a laterally projecting pin 70 extends into any one of a plurality of apertures 71 formed in the standard 60. It will be noted that when the up er end of the lever 63 is pulled backwar the furrowturning member B being assumed to be in working position, the connecting means between the lever and said member will be moved in a direction-which raises the member to transport position. In order that the member may be adjusted to working position, when the implement is standing on unp lowed land, the crank 66, as shown best in ig. 8, has its upper end bifurcated and withinthis bifurcated portion there is disposed a jou-rnaled bearing 72 through which the rod 65 extends loosely. The rod projects forwardly beyond the bearing and its projecting end is encircled by a spring 78, one of whose ends preferably abuts against a stop 74 on the rod and the other of whose ends preferably abuts against the forward surface of the bifurcated portion 66 of the crank 66. It will be seen that when the implement is standing on unplowed land and the lever 63 is thrust forward the rod 65 will be moved through the bearing 72, thereby placing the spring 73 under tension such that it exerts pressure upon the member B through the crank 66, shaft 67 crank 68, link 69 and standard 60, which pressure aids the force of gravity in the lowering of the furrow turning member to its working position when the plow enters the land. The movement of the rod 65 relatively to the crank 66, permitted, by the connection described, enables the lever to be thrust forward to a position beyond that defined by the engagement of the furrow-turning mem her with the land and hence the furI0W-turn-' 65 ing member may be set to work at a predetermmed depth while the implement is menses .fixed in its predetermined position, prefstanding upon unplowed land. A shoulde is provided on the rod to limit move ment of the arm 66 under influence of th spring and prevent excessive downwar movement of the member B. The lever i.

erably by a latch 75 (Fig. 7) arranged tr engage any one of the teeth of a segment 7 6 the latch being preferably operated by means of a grip 77 connected with the latc-l by a link 78. The segment 76, instead 0 being fixed is pivoted, preferably On th pivot 6a of the lever 63, and a spring 79 extends from the segment to an appropriate part of the frame, to which it is secured. In practice, it is preferred to connect the forward end of the spring to a bolt 80 adjustably mounted in a projection 81 fixed upon the frame member 10, this connection permitting the tension of the spring 7 9 to be adjusted. It will thus be seen that when the lever is released by disengaging the latch from the segment, the lever may be moved relatively to the segment, to adjust the height of the forward furrow-turning member relatively to the frame and that when the said furrow-turning member has been adjusted to working position and the lever has been locked to the segment, the furrow-turning member is under the influence of the spring 79 and is enabled thereby to adjust itself automatically to accord with varying conditions which may be encountered in the operation, such as obstructions, depressions or soft placesthe segment, the lever, and the means connecting the lever with said member, moving as a unit.

The adjusting mechanism for the rear furrow-turning member E is preferably substantially like that employed for the forward memlber except that the position of the rear member with relation to its 'actuat ing lever, marked 82, is such that the rod 65 is dispensed with. In other words, the segment 83 is pivoted and a spring ea extends from the segment to an attaching means 85 carried by an appropriate part of the frame; the lever has a latch for locking it in various selected positions to the segment and its lower end is secured directly to a shaft 86, corresponding to the shaft 67 having a crank 87 with a lateral projection 88 extending into any one of several apertures proiuded in the standard 60 of the rear member i E. This standard is vertically adjustable through an appropriate guide frame 61 having rollers 62 arranged to engage its front and rear edges. While this means connecting the rear furrow-turning member with its adjusting lever does not permit a setting of the lever beyond the point defined by the surface of the land, that is to say, while it does not employ any relatively movable connections between the'lever 82 and the crank 86, it should be noted that when the rear furaeaeoe row-turning member is so ,as it is normally in ordinary plowing, in line with the bottom of the traction wheel A, the depth of thefurrow made by it is always the same as that made by the front plowing element and hence there would be no particular advantage in providing means, such as are exemplified in connection with the forward furrow-turning element, for permitting a movement of the adjusting mechanism beyond that defined by the land when the implement is standing onunplowed land. In other words, the only adjustments needed for the rear plowing member are adjustments above the plane of the lower surface for working purposes.

Particular attention is called to the fact thatthe yieldable mountings for the furrowturning members not only enables said memto yield to obstructions but. further enables them to adjust themselves auton'iatically when depressions or soft spots are encountered in such manner that the traction of the wheel A is not diminished. l'n plowing with one furrow-turning member ahead and the other behind the traction wheel, any depression or soft spot in the land would cause the weight of one side of the implement to rest on the furrow-turning members-and if these members were rigidly sup ported thetraction of the wheel A on the land would .be diminished and said wheel would spin around, because of its failure to get a firm grip on the land under it. But by the use of the springs, the furrow-turning members will yield to the weight imposed on them, thus permitting the traction wheel to get a firm grip on the land under the varying conditions referred to.

It will be understood that the land wheel C is an idle wheel and that it is mounted on a crank shaft 100 having the ordinary, or any suitable means, for adjusting it to accord with the depth of plowing, this wheel running on the unplowed land while the guide wheel. the traction wheel and the plowing members run in furrows, as hereinbefore explained.

The furrow-turning members, being independently adjustable. one may be set. to

working position and the other in transport position, if required for any reason-when the soil is too hard for both to be used, for example. 7

While I prefer to employ two furrowturning members of the single moldboard type, arranged respectively in advance and at the rear of the traction wheel, I, nevertheless, wish it to beunderstood that I do not limit myself in all respects to this particular number, type or arrangement of soilturning members.

a It will be noted that the frame has its member 10 arranged substantially in alinement with the longitudinal axis of the implement and that the front member 13 converges forwardly toward the forward end of the member 10, and also that the uniting or connecting member 15 is substantially triangular in shape andhas its rear portion extending between the members 10 and 13, its said portion being said members. Further, it will be noted that the member 15 extends forwardly from the front ends of the members 10 and 13 and this forward portion carries the driving wheel. Still further will it be noted that the frame has substantially a trapezoidal shape and that the longitudinal axis of the trian ilar connecting member 15 lies substantial y in that diagonal of the trapezoid which extends from the convergent angle of the members 10 and 13 to the angle of the members 11 and '12. By this means the thrust of the guiding wheel is transmitted through the frame members in such manner as to take up the stresses incident tosuch thrust in a highly efficient way. It will also be observed that the quadrant 76 is provided with a stop TGwhich. when the quadrant is in its normal position contacts with the bracket 6a which supports the pivot 64 of the quadrant.
