1 '0 all whom it may concern:

Be it known that I, Lnwrs E. WATERMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Two-Way Plows, of which the following is a specification.

This invention relates in general to plows, and particularly to reversible or two-way plows adapted for hillside plowing. More specifically, the invention relates to the class of two-way plows having bails on which the plow beams and carrying wheels are mounted and which are operated either manually by hand levers or by power from the carrying wheels to raise the plows. By reason of the fact that the carrying wheels are customarily mounted on fixed axes on the bails the wheels are maintained in fixed vertical relation with respect to the frame whether in raised or lowered position. The result of such a construction is that the carrying wheel traveling in the furrow can not effectively resist the side thrust of the plow, consequently, uneven strains on the bearing of the furrow wheel and an increase in the draft result. Furthermore, the wheel treads in the furrow in so nearly an upright position as to strike against and tear down the side wall. thereof, thus clogging the wheel, increasing the draft and causing the wheel to frequently run out of the furrow, all of these undesirable features being accentuated in proportion to inclination of the hill-side being plowed.

My invention aims, primarily, to overcome these objectionable features and to this end I have devised a two-way plow in which the carrying wheels may be tilted laterally relatively and with respect to the frame so as to most efliciently serve their purpose as carrying members and to effectively resist the side thrust of the plows, thus materially decreasing the draft.

More particularly, I have provided twoway plow in which each carrying wheel and its adjacent plow may be raised and lowered in unison and the carrying wheels will be automatically canted laterally during such movement so that when the plow is raised the wheel will tread in a vertical position relatively to the frame and when the plow is lowered the wheel will tread in an inclined position in its furrow, canted outwardly with respect to the vertical axis of the frame.

Other objects and attendant advantages will be apparent as the invention becomes better understood by reference to the fol. lowing description when considered in connection with the accompanying drawings, in which Figure 1 is a side elevation'of a two-way plow embodying my improvements, showing the left hand moldboard in working position;

Fig. 2 is a side elevation of the plow showing the right hand moldboard in raised position;

Fig. 3 is a plan view of the plow; and

Fig. 1 is a rear View thereof.

The frame of my improved plow is of comparatively simple design consisting of a cross beam 6 having rearwardly turned ends 7 an angle iron beam 8 positioned above the beam 6 and segment brackets designated generally by reference character 9 to which the ends of the cross beams are bolted. A pair of plow' carrying bails 11 are pivotally mounted at their inner ends on a common pivot bolt l2carried by rearwardly projecting supporting plates 13 bolted to the cross beam 6 and are pivotally mounted at their outer ends on pivot bolts concentric with the bolts 12. It will be, noted that'each bail is formed in two parts, the outer arm 15 being a separate part. This arm at its free end is provided with a sleeve 16 through which the forwardly turned outer end 17 of the main part of the bail projects longitudinally of the machine. A set screw 18 secures the arm 17 fixedly to the sleeve 16 so that-the bail is in efi'ect an integral structure. Each bail carries a suitable plow beam 19 equipped with amoldboard. A drivers seat may be mounted on the frame. A tongue 21 is suitably connected to the frame, and as is well under-v stood in the art means, not shown in the present instance, may be provided for adjusting or swinging the tongue laterally with respect to the frame to take care of the side draft of the implement when plowing on difierent grades. 7

Upon the arm 17 of each bail is pivotally mounted a yoked bracket 22 carrying an axle 23 secured rigidly thereto, and on each axle is journaled and suitably secured a carrying wheel 24 equipped at its inner end with a toothed ratchet wheel 25. By reason of this construction, each carrying wheel and its plow beam may be raised and lowered with respect to the frame by simply swinging the bail on its pivots and the swung backwardly and forwardly by hand in the usual manner to rock the bail and at the same time a lateral tilting movement is imparted to the'lever by the cooperating segment which is mounted at an angle to the longitudinal aXis of the machine.

The segment 9 having a toothed underface 26 is shaped to extend outwardly and rearwardly from the cross-beam, thus providing a laterally inclined cam way 27. The hand lever 28 fixed to a bracket 29 in turn rigidly secured or formed integrally with the yoked part 22 is equipped intermediate its ends with an inwardly extending bracket 31 that carries a pair of cone shaped rollers 32 arranged to engage the inner and outer sides of the segment 9 so as to slidably associate the hand lever with the segment and maintain the lever in fixed relation thereto at all. times. Thus when the lever 28 is swung back and forth on the pivot aXis of the bail to raise and lower its plow, it is also tilted laterally due to the lateral inclination of the segment, this lateral tilting movement of the lever being independent of the bail on the axis of the arm 1'? thereof. Since the lever 23 is in effect integral with the axle. 23, the latter will also be moved about the axis of the arm 17. The effect of this construction is to cant or tilt the carrying wheel from a vertical to an outwardly inclined position such as is shown at the left of Fig. 4 when the hand lever is moved from its foremost to its rearmost position to lower the plow into the ground.

Means are provided for locking the hand lever to the segment and for operating the lever by power to raise its plow to inoperative position. This means'comprises a dog carrier 33 embracing and slidably mounted on the lever 28 and equipped on its inner side with an integral dog 34 adapted to engage, the notched face 26 of the segment. An expansion spring 35 operating between the parts 33 and 29 constantly urges the dog 34'toward the notched face A dog 36 slidable in a guideway 37 integral with the bracket 29 and connected at 38 to the carrier 33 is adapted to be moved into and out of engagement with the ratchet wheel 25 by movement ofsaid carrier 33 longitudinally on the lever. The dogs 34 and 36 are so were relatively arranged that when the dog 34 is engaged in the face 26, the dog 36 will be disengaged from the ratchet wheel and so that the dog 34 may be moved out of engagement before the dog 36 is moved. into engagement with its respective toothed face. The dog carrier 33 normally urged into locking connection with the segment 9 by means of the spring 35 may be operated by a hand lever 39 to withdraw the dog from its segment. For this purpose the hand lever 39 mounted on the lever 28 and connected to the slide member 33 through means of a link 41 may be moved in a counterclockwise direction viewing Fig. 1. A second lever 42 mounted on the lever 28 is provided for moving the dog carrier 33 farther downwardly to engage the dog 36 with the ratchet wheel. The lever 42 is connected to the slide member- 33 through means of a link 43 and it will. be noted that this further downward movement by the lever 42 does not affect the lever 39 because of the slot connection between the latter and the link 41. The lever 42 may also be operated by means of a foot lever 44 pivoted at 45 to a depending extension of the segment 9 and having its outer end connected at 46 to a link 47 which is connected at.43 to the lever 4. By means of the foregoing operating mechanism the operator may cause the plow to be raised from the ground by power either by pressing forwardly on the foot lever 44 or by operating the hand lever 42, which operation as already explained will disconnect the lever 28 from the segment and engage the dog 36 with the ratchet wheel, causing the plow to be lifted by the rotation of said wheel. When the plow is elevated to a predetermined position, the dog 36 will. be automatically disengaged from the ratchet wheel and simultaneously the dog 34 will be moved into engagement with the notched face of the segment thereby locking the plow in raised position. This result is effected by means of a roller 49 mounted on the upper end of the dog carrier 33, which roller engages and is operated by an inclined cam 51 disposed forwardly on the peripheral face of the seg ment 9, it being obvious that as the lever is swung to its foremost position the roller 49 will be moved up the incline 51 and opera ate the dog carrier 33 for the purpose described.

lt will be understood that the plow and wheel carrying and operating mechanism at each-side of the frame is identical in construction and operation and that when plowing on a side hill the plows are used alternately in plowing back and forth. For instance, with the left hand plow in operation the plow is raised at the end of the furrow, the implement turned about and the right hand plow lowered into the ground to turn up the next new land. In plowing in this manner with my improved plow, it will be apparent that when either plow is raised or lowered its carrying wheel is simultaneously and automatically angled or tilted laterally to a desired and most effective working position. With the left hand plow in the ground its adjacent wheel assumes the laterally inclined position shown in .Fig. 4c, in which it will be noted that the wheel treads in the corner ofthe furrow and is in no way liable to tear down the edges-of the furrow wall and to become clogged with dirt thereby. Furthermore, the carrying wheel when treading in this manner serves to most effectively carryand resist the side strain or thrust of the plow. In this connection it will be noted that the axle bearing because of its inclined position and of the direct manner in which the side strain carried by the wheel, is not subject to the severe uneven wearing strain which theaxle of a furrow wheel in upright position would receive. These features all promote lightness of draft since the plow is carried and guided in most eilicient manner and they in no way impede the plowing or present abnormal wearing or working conditions. While I have utilized the segment bracket to effect lateral movement of the carrying wheels, it should be understood that I do not limit myself to this particular method for accomplishing the objects desired since various other means might be employed for the same purpose. changes might be made without departing from the spirit and scope of the invention or sacrificing any of its material advantages.
