In the drawings:

Figure 1 is a plan view ofa two-'wa gang plow with the right hand gang in operative position.

Figure 2 is an enlargement of the right hand end of the cross member and adjusting shaft.

igure 3 is a section on Fi ure 2.

Figure 4 is a side View of Figure 1.

Figure 5 is a detail of the wheel elevating mechanism.

Figure 6 is Figure 5.

Figure 7 is a section onthe line 7*7 of Fi ure 5.

Figure 8 is a rear view of the main frame with parts broken away. Similar reference-characters through the severalviews indicate the same parts.

In the drawings 10 and 11 are plows which constitute one set while 12 and 13 constitute the other set, rigidlysecured to separate plow carrying frames one of whlch comprises the parts 14, 15, 18 and 19 and the other the 20 and 21. As shown, each set or gang of plows is arranged at a fixed horizontal rearwardly divergent angle with the other and is pivotally secured to the horizontal draw pin 22 to which is attached the attaching member or single point of attachment 22 of the drawingforce of the machlne. Thus the gangs may swing vertically in rearwardly divergent planes into or out of operative position independently of each other.

April 10, 1928, Serial No. 411,558, filed September 20, 1920. Application for Serial ,No. 292,392.

Suitable side bars 23 and 24 are pivotally secured at 26 and 27 to the arched cross member or main frame of the machine to swing vertically but not laterally relatively there to, and support the draw pin 22 at their converging front ends so that said bars cause fixed point of attachment 22 to be always in a fixed angular relation to the two sets of plows and yet permit the point 22 to raise or lower with any unevenness of the ground. The side bars as, with the draw pin 22 which connects them, constitute a fore or draft frame by which the draft of the tractor or other drawing power is transmitted to the main frame and to the plow units.

In the construction illustrated a rear frame is provided, which comprisesthe' side bar-s28 fixedly secured to the cross member or inain frame 25 and carries a rear supporting wheel in the form of a caster wheel 29 pivotally mounted at 30, so that such wheel may always be automatically alined with the direction of movement of the machine. I

Depending'from the side oars 28 of the rear frame are the guide aprons 33 and 34:,

shown in Figure 8, between the bottom edges of which are secured the strengthening and supporting pieces 35 and 36 which prevent the operative plow from digging into the ground any more than a maximum. amount below the main frame shouldthere be any tendency thereto.

The depth of the furrow is regulated by the height of or the adjustment of the main side supporting wheels 37 and 38, which are diri glble, and are separately vertically adjust able by having the axle 39 of each wheel bent around to constitute a vertical or upstanding portion 47v slidable in the guide channels 48 provided with securing pieces 49 and bolts 50 to hold the upstanding projections l? in place in the guide channels. The dirigible wheels 37 and 38 are always in parallelism and are pivotally secured to the arched main frame or cross member 25 by means of the pins 40 at each end thereof. In order to dispose these dirigible side wheels at different angles relative to the cross or transverse member 25, an auxiliary bar 41 is pivoted at each of its ends at 42 to the projecting arms 43 and 4A fixed to the guide channels 48.

For purposes of adjusting the wheels at the desired angleto the main frame, a handle 45 is sec'ured tothe auxiliary bar ll and pivotally attached to the cross member and co operates with notches 46 ina plate attached to the main frame'in order tohold the handle Y a a w a H for many years, but they have not proven en 45 and the side wheels 37 and 38 movable therefrom in the angularly adjusted posi tion. In the embodiment shown there are only three positionsillustrated for the wheels,

the midposition with which the handle 45 cooperates when the wheels are substantially at right angles to the cross member 25 for,

drawing the plow with neither set of tools in operative position, the left hand notch with which the handle 45 cooperates" when the plows 1O and 11 are in operativeiposition, and the righthand notchin which the handle is shown cooperating when the right hand gangis in working position.

. Each of the side wheels 37and 38 has edly secured thereto to rotate andalso to turn angularly therewith, power transmitting 11183113111 the fOI'IIL Of a large driving gear 51', one of which isadapted to, cooperate with one of the driven gears52 when either gang of plows is working. The driven gear 52 drives the adjusting shaft 53 which is fixed relative, to thetransverse arched or, cross mem- I ber 25 and contains theiiniversal joints 64; v necessitated by the angular disposition of the ends; of the shaft. Provided. on the, adjustingshaft 53 but freely rotatable thereoniare the winding drums 54; and 55 for independently elevating either wheel or moving either an of lows to an 1110 aerative. osition.

These winding drums may be rotated by means o f the complementary cooperating,

clutch ,members'54 'and55 each of which is "keyed to the shaft 53 but slidable thereon by means of the'operating levers'56, 56, 57211121 position if tractor drawn.

57 res nectiv'el which ma lea'd'to a position 1 ya, 7y i adjacent the drivers seat if the device is used as a sulky plow, or may lea'dto the operators In order to raise or lowereach wheel, a lug 58 projects from the upstanding portion 47 of the axle through the back ofthe guide channel 48to which is attached a chain or cable 59 passing downwardlyaovera pulley or sheave 60 fixed to the, main frame and upward to the winding drum 55, For lifting eith'er set of plows out of operative position, a chain or cable 61 passes "over each winding drum 5 l to the pulley 62 v and down to the cross pieces 19 and2O to which the-lower end of the cableinay be at-. L tached. Retractile springs 63 hold the o-perating levers 56, 56, 57 and 57 normally in a position in which the complementary clutch, members do not cooperate. Whenany co--,

operating clutch member engages its winding drum to rotate thesaine. the drum .may be held in a partially or fully wound position by means of spring pressed pawls 65, 65 65 and 65 cooperating with the ratchets 66 fixed on each winding drum. Releasing rods 67,

67*, 67 and 67 also leading'to the drivers or operators position are prov ded for'releasing the pawl in order that any onset the winding drums may be unwound much as desired. Two-way plows have been known and used tirely satisfactory because it has been impossible with the constructions heretofore known to keep the center of resistance of both plowing'units, when each is inoperative position, in a common line of draft; in other words, the

construction has been such that shifting from one plowingunit to the othershifted the line of draft laterally with reference to the point of application of the draft to the plow, whereas the best resultsare obtained by maintain ingtlie line of draft constantly in a longitudinal vertical plane coincident withthe center ofpowerof the tractor or other drawing were placed at opposite sides of such center line and were arranged to move upand down in parallel vertical planesin fixed relation to the frame and its supporting wheel's. in,-

vention, however, provides for bringing the center of resistance of either unit when in, operation into coincidence with a common" i.-"

central line of draft, and maintainingit in such POSltlOIl, as will be readily, understoodv o from the following description of the operation thereof.

that one set or gang of plows, for instance the right hand set, may be in properworking position, the handle 45 is moved to cooperate with theright hand notch as indicated, thereby turning the side wheels 37 and 38 about their pivots 40 to direct thenitoward' the left in parallelism with eachother.

The right hand gang having beenv lowered to its operative position,v if the machine is, being drawn during this operation, by reason I;..

of the location of the center of resistance at In operation,to adjust the plow in order the right hand side of the median line of the plow vhich temporarily deflects the line of draft laterally in that direction, the force of the draftwill swing the main frame laterally about the single point of attachment 22,

carrying it to the angular position shown in Fig. 1, so that the wheel 37 will be moved ahead ofthe wheel 38 and both wheels will be restored to parallelism with the line of advance, and with the center line of draft,

with whichthe point of attachment 22 and the center of resistance of the operating plow unit will then aline. Thus a single shifting means is provided forthe frame, plows, and

operative plow, the sliding lever 57 or 57 may be moved into cooperation with whichever winding drum is desiredto be operv ated when the cable will be wound and wheel adjusted relative to the main frame the desired amount, after which the operating lever 57 or 5'? may be released to disengage the co-operating clutch members,

' At the end of the furrow should it be desired. to operate with the other gang, the set of plows 12 and 13 may be elevated to an inoperative position by operation of a lever 56 to windthe appropriate drum 54: the desired amount. To lower either set of plows the pawl. releasing rod 67 or 67 may be operated to, i'elease'the pawl or ratchet and allow the desired drum 5a to unwind. In the same way operating the rods 67 or 67 releases the pawl and ratchet of the desired winding drum 55. It will be seen that if the machine is in motion, by operating the handle 45 to turn the steering wheels toward a position of parallelism with the deflected line of draft incident to the lowering of either gang to operative-position, by the force of the draft the main frame, fore frame, and both wheels will move laterally, turning about the single point of attachment 22 as a pivot, to carry the center of resistance of the operating gang into substantial coincidence with the normal central line of draft and restore the steering wheels to parallel position of alinement with the normal central line of draft, and not only restores the d' 'Q'ible wheels to a-position of parallelism dz/till the line of advance but at the same time moves the land wheel ahead of the other for a better distribution of forces within the )lOW frame and a better uidine' of the ma l V t: o

chine. 7

When the sets or are d sposed at a fixed horizontal oblique angle to each other, an advantageous lateral spaceeconomy results since theinoperative plow is then disposed back of the wheel on the land side in an out of the way position instead of being" placed above or at the side of the working plow. The ease of adjustment of the depth of the furrow by adjusting the height of each wheel independently of the other, which adjustment is accomplished from the rotation of the side wheels of themachine when in motion is another noteworthy feature.

Also the fact that either set of plows may be retracted to an inoperativeposition by the same adjusting shaft 53, driven from one of the side wheels is a further advantage. lVith the plows arranged at a fixed horizontal angle with one another, a rigid and substantial frame results for the two-way plows. One of the most noteworthy features of my invention is the single point of attachment 22 in fixed angular relation to the two plows for applying the drawing force to each plow,

while the wheels, plowing units and main frame are movable under the force of the draft to carry the center of resistance of the operating unit into the normal central line of draft, and maintain it in such position while it continues in operation. Having the point of attachment 22 fixed relative to the two plows enables a lighter frame to be used and yet affords the necessary rigidity.

Although I have shown and described the invention embodied in a two-way gang plow, it will be readily seen that either set or gang of plows may be regarded as single tool so that the term tool as used in the claims refers to one of the two-way plows which may be either a single plow or a gang.
