State of Kansas, have invented certain new and useful Improvements in Lister-Flows, of which the following is a specication, reference being had to the accompanying drawings.

This invention relates to improvements in lister-plows and has for one of its objects the provision of means for enabling the plowbody and the frame to which it is attached to be moved, at the completion of each furrow, from one side of the machine to the other. Such movement of the plow-body allows two important ends to be attained, which are, in the order of their importance, lirst, the double listing of the field, and second, the plowing of the first and last furi rows closer to the boundary fences of the field than would be possible where the plow body remains in a fixed central position relative to the supporting wheels. By double listing is meant bursting out previously formed ridges between successive furrow's, spaced the usual distance apart, and forming in place of such ridges additional furrows for the reception of seed. Such double listing is becoming increasingly popular as its advantages are recognized. Such advantages are that the ground is of course more thoroughly plowed; it is put in better shape for cultivating; it absorbs excessive rains better; the deposited seed is not so liable to be washed out, and the roots of the plants are given a better chance to extend themselves-all of which results in a larger yield. Vhile the above-recited advantages of double listing are quite generally recognized, it is frequently not resorted to owing to the diiiiculty of properly accomplishing it with the ordinary lister-plow, for in doing it with an ordinary lister-plow-that is, one where the plow-body remains at substantially the i longitudinal center of the machine-much depends upon the skill of the operator in driving his horses and also upon the correct walking o-f the horses. Indeed, the utmost care is constantly required to prevent the plow from being deflected to one side of the center of the ridge and into one of the adjacent previously-formed furrows.

By my improved construction wherein the plow-body is maintained at one side or the other of the machine the difliculty Aof maintaining the plow-body centrally of the ridge is obviated. To lso maintain it I space the supporting wheels a distance apart substantially equal to one and one-half the distance between the rows that are formed .for single listing (instead of twice the distance between such rows as is commonly done with wide-tread listers) and, therefore, am always enabled to utilize previously-formed furrows as guides or gages for keeping the plow-body properly positioned with respect to the ridge that it is working upon. One of such guiding or gaging furrows for the double-listing operation is a furrow previously made in single listing while the other one will be 'a furrow made in the doublelisting.

When the machine is used for single listing it is necessary, of course, at the end of each furrow to level up the machine by depressing the wheel-frame at one side of the machine and correspondingly raising the frame at the opposite side, for, of course. the wheels alternately run in a furrow and on the unplowed ground. It is one of the objects of the invention to provide improved leveling means which can be either manually operated by the driver from his seat or be automatically operated which latter I consider preferable) by the shifting of the plow-body from one side of the machine to the other. These stated leading objects of the invention I accomplish by the devices and combinations of devices illustrated in the drawings and hereinafter particularly described. That which I believe to be new will be' pointed out in the claims.

Fig. 9 is a vertical section taken at line 9 9 of Fig. 8.

Referring to the drawings in which corresponding parts are indicated by like reference numerals-10 indicates a double moldboard lister plow-body, andv 11 the beam therefor, which beam is mounted in the usual. manner upon a crank shaft 12 the ends of which are journaled in suitable brackets 13 secured to the side members of a plow-supporting frame 14, which frame is supported at its rear end by a pair of caster wheels 15 and near its front end by side wheels 16,- the particular means of connecting the frame 14 with the side wheel members being hereinafter set forth. On one of the side members of the frame 14 is secured a mental rack 17 with which coperates a hand lever 18 rigidly connectedv to the crank shaft 12 whereby the plow is raised or lowered as desired relative to the frame 14, and is held in its adjustedposition by the engagement of an ordinary spring latch on the lever with one of the notches of the rack. In rear of the plow-body is shown a seed hopper 19' supported by inclined disks 20, the rotation of which operates seed-dropping mechanism at the bottom of the hopper, as usual, so as to cause discharge of seed through the inclined spout 21. The supporting wheels 16 are each supported on axle members or spindles 22 that extend outward from the lower ends of two vertically-disposed standards 23. Against the inner face of each of these standards 23 is arranged a bar 24, these two bars being connected together by upper and lower cross-bars 25 and 26, respectively, which as shown are preferably made of pipe sections. These vertical bars 24 and cross-bars 25 and 26 form a frame, which, together with the standards 23 that carry the supporting wheels, may be considered as a wheel frame. Each standard 23 is connected to its adjacent vertical bar 24 by clips 27 which are made fast to the bars 24 andl embrace the standards in such manner that the bars 24 can. be moved vertically relative to the wheel standards. The two cross-bars 25-26 are braced together at their central portions by braces 28 bolted to them, said braces in turn being secured together by a bolt 29 (see F 5). The supporting frame 14 is connected to the wheel frame and supporting frame by means of an arch member formed of a front and rear section 30-31, respectively, said sections being spaced apart a suiiicient distance to accom modate between them the cross-bars 25-26 '70 of the wheel frame. The horizontal portions of these arch sections are connected together by suitable bolts 32 and their vertical portions are secured together above and below the lower cross-bar 26 by bolts or rivets, 75 upon which bolts or rivets are rotatably mounted rollers 33 that bear against the upper and lower sides of such cross-bar 26. 34 indicates two brackets afliXed respectively to the central portions of the horizontal members of the arch 30-31, in which brackets is journaled the forward end of a rod 35 that has suitably afIiXed to it between the said horizontal members of the arch a gear 36. rThis gear is in mesh with a rack bar 37 that is secured in any suitable man- -ner to the upper surface of the upper crossbar 25. The rear end of the rod 35 passes through and is ournaled in the rear end of a long bracket 38, which, as best shown in vFig. 5, is here constructed of a single bar bent centrally and having its ends turned and bolted at opposite sides of the central portion of the rear member of the arch 30 31 being shown as secured by two of the 95 bolts 32 before referred to. 39 indicates: an annular plate axed in any suitable manner to the rear end of the bent bar or bracket 38, through which plate the rod 35 projects. The plate 38 has a rearwardly extending 100 flange in which, as clearly shown in Fig. 5, are formed a plurality of notches. 40 indicates a crank that is pivotally attached to the rear projecting end of the rod 35 and by means of which the rod 35 is rotated. The 105 crank handle by reason of its pivotal connection with the rod is adapted to be pushed forward, as shown in Fig. 2, so as to engage with one of the notches in the plate 39 and thereby lock the rod against further rotation. 41 indicates two diagonal braces bolted at their upper ends to the forward' member 30 of the arch and at their lower ends to the respective side bars of the frame 14.

As clearly shown, the lower ends of the vertical legs of the double arch 30-31 are bolted to the frame 14 near the forward end thereof, and, therefore, constitute in effect a part of the plow-supporting frame 14. lli/'ith 120 the plow-body raised out of the ground it is evident that such plow-body and its supporting frame, comprising the members 14 and 30-31, together with the parts attached to those members, can be shifted laterally of the wheel frame as may be desired, this being accomplished by the operator from his seat rotating the shaft 35 by means of the crank handle 40. Suchr rotation causes, of course, a rotation of the gear 36 affixed to 130 the forward end of the shaft, and as it is in constant engagement with the rack-bar 37, the arch 30-31 and the parts secured thereto are necessarily moved laterally of the machine. When moved to the eXtent desired, the arch is to be locked in that position by the driver causing an engagement of the crank handle with one of the notches in the anged plate 39.

Where trenches or furrows are to be formed as in ordinary listing-known as single listing-one of the supporting wheels 1G runs in the last trench or furrow that has been made while the other of such wheels runs upon the unplowed and consequently higher ground, and hence it becomes necessary at the beginning of each furrow to level the machine by suitably raising that wheel which had before run in a furrow and correspondingly lowering the other wheel which is now to run in the last made furrow, but which had previously ran on the unplowed ground. To accomplish this levelingoperation, I provide two parallel cross-bars 42 each centrally pivoted upon one of the braces 28 that connects the two bars '25 and 26 together. These crossbars 42 are shown as pivoted against the outer faces of these two braces 28, the bolt 29, heretofore referred to, constituting the pivot. The ends of these cross-bars 42 are connected to the two wheel standards 23 so that as such cross-bars are rocked upon their pivot they will, relatively, raise one such wheel standard and its wheel and correspondingly lower the other wheel standard and wheel. As shown in the drawings, the connection between the cross-bars 42 and each wheel standard is made by reducing the ends of such cross-bars and projecting them through the end portions of short strips 43 that are secured to the outer faces and near the upper end of said wheel standards. Any other appropriate manner of securing the cross-bars to the wheel standards could, of course, be employed. To the outer face of one of the vertical bars 24 and close to its upper end is rigidly secured a toothed segment 44 that projects rearwardly. Pivoted alongside of this segment is a lever 45 provided with an ordinary spring latch for engaging the teeth of the segment, such lever being preferably slightly inclined toward the center of the machine to be more conveniently in reach of the driver. To this lever, forward of its point of pivotal attachment to the segment, ispivotally attached the upper end of a short link 46, the lower end of which is pivoted to the central portion of the outer face of that short strip 43 at that side of the machine. It is evident that by a movement of the lever 45 that one of the bars 24 that is connected to the lever by means of the rack 44 will be moved either up or down accord ing to the direction of movement of the lever, and this will, of course, cause a relative reverse movement of the adjacent. standard 23 and also a turning of the cross-bars 42 on their central pivot and impart a corresponding relative movement in the reverse direction, to the other wheel standard with which said cross-bars are connected. A single movement of the lever, therefore, raises one side of the wheel-frame and lowers the other side to the same extent, and hence, the desired leveling of the machine can be quickly accomplished.

In practising single listing, some vfarmers desire the width between furrows to be a little greater than others, and accordingly the supporting wheels 1G are preferably made laterally adjustable on their respective spindles and when adjusted as desired fixed in place in any usual manner; such differences in width can also be accomplished by the extent to which the plow and its supporting framework are shifted laterally, and it is because of the fact that it may not always be shifted to the extreme extent to one side or the other that I provide the flange of the annular plate 39 with a plurality of notches which enables the handle to 'be locked in place' as described regardless of the radial position that the handle is in when the locking of the parts is to be effected. During all of the plowing` operations, however, it is the intention when using my improved machine to have the plow-body located well toward one side of the machine, whereby the furrow being formed will be at the desired distance from the previously formed furrow in which one of the supporting wheels is traveling, as is clearly illustrated by Fig. G. Upon the completion of the furrow. the machine is, of course, turned around preparatory to making the next furrow, and the wheel that had been running upon the unplowed ground is directed into the last-named furrow to serve as a guide. It is then, of course, necessary that the plow-body be shifted toward the opposite side of the machine so that it occupies the same position relative to the wheel at that side that it had previously occupied with respect to the other wheel. IVhcn so shifted. and the leveling operation having been performed as described, the furrow then to be made will be properly spaced from the previous furrow. It is with especial reference. however. to double listing that the shifting of the plow-body from side to side for the formation of successive furrows applies. As before stated, the furrows or trenches formed in the practice of double listing are formed between the single listing furrows or trenches and the spaces where these double listing furrows must he formed are difficult to accurately plow owing to the quantity of dirt that has been thrown in ridges by the formation of the single listing trenches. By making the wheel frame of my machine approximately one and onehalf times as wide as the distance between single listing furrows or trenches, I am able to run both of the supporting wheels 16 in trenches, as indicated clearly in Fig. 7, and by so doing I obtain by the two trenches that the wheels run in a perfect guide for the forward progress of the machine, and those two trenches that the wheels run in also act to counteract any tendency of the plow-body to run out of a straight line,- to wit, out of the center of the ridged space before mentioned. ln the view shown in Fig. 7, the trenches indicated by a are those formed in the process of single listing while those indicated by are those formed in the process of double listing, and it will be noted that one of the supporting wheels runs in one of the trenches a while the other runs in one of the trenches Y). This must always be so after the formation of the first double listing trench or furrow, and this very valuable feature of providing` a guiding and retaining trench for each wheel to run in during the making of a trench in the ridged space between two single listing trenches is made possible not only by reason of the lateral shifting of the plow-body for the formation of successive trenches, but also by reason of the formation of the wheel frame of a. width that the wheels thereof are spaced apart approximately one and one-half the distance between adjacent trenches made in the single listing. The width of the wheel frame, therefore, bears a very distinct relation to the work to be performed as it permits th e carrying wheels to run in; the trenches designated as L and and also permits the plow-body to be adjusted with proper relation to the ridged space between two of such furrows or trenches that are indicated by a.

With the machine employed in double listing there will be no occasion, of course, for leveling the machine, at the completion of each furrow or trench because both of the wheels will travel on the same level, and`v therefore, the adjusting lever 45 will be moved to a proper position to hold the leveling cross-bars 42 horizontally. i

In single listing it is necessary, as hereinbefore pointed. out, to level the machine at the completion of each furrow in order that the wheel which had run in a furrow should.` during the next traverse of the field, run on the higher unplowed ground, and vice versa, and while I have shown in Figs. l, 2, B and 4 a very simple and effective means for manually accomplishing such leveling, the operation is capable of being, and preferably, performed automatically upon the lateral shifting of the plow-body and its supporting frame, and such automatic means is illustrated in Figs. 8 and 9, to which reference is now made. ln these igures,show ing the modification, the parts that correspond in construction to those heretofore described are indicated by the same reference numerals with the addition of the letter a. In this construction the leveling cross-bars are not centrally pivoted in place on a fixed pvot as in the other construction, but the rear one has pivoted to it at 47 two bars 48, the pivot 47 for each bar being substantially midway between the ends of the bar. The bars 48 at their inner ends are pivoted together by a pin 49 and from this pivot pin 49 depends a link 50, the turned lower end of which is engaged by the short end of a hand lever 5l that is pivoted at 52 to a segmental toothed segment 53, bolted to and projecting rearwardly from the rear brace 28a that extends between the two cylindrical cross-bars 25a and 26a. The lever 51 is provided with the usual spring latch for engaging the segment and it is evident that 'by the use of the lever the bars 48 can be turned on their pivots 47 to any required position. 0n the rear face of each depending leg of the double arch member 81a is journaled a roller 54. Each of these rollers is so positioned with respect to one of the bars 48 that as the arch 30a-81L is moved toward the side of the machine the roller will come in contact with the lower edge of its adjacent bar 48 and force the same upward so that it turns on its end pivot 49. This upward movement, of course, is transferred through the pivot 47 of that bar to the cross-bar 42a causing the adjacent end of such bar 42a to rise. The other end is correspondingly lowered, and, as the ends of this cross-bar 42"L are connected, as above described, with the wheel standards, it is evident that one wheel is relatively lowered to the same extent as the other one is raised. lt is evident that automatic leveling will be effected in the manner described at each lateral shifting of the plow-body and its supporting frame, one roller 54 contacting one of the bars 48 when the plow is moved toward one side while the other roller 54 causes a movement by contact with the other bar 48 when the plow and its frame are shifted to the other side of the machine. Of course, in double listing no leveling movement will be required, and, therefore, through the lever 51 the inner ends of the bars 48 are pulled down to bring such bars into alinement with each other and parallel with the cross-bar 45%L which latter will itself assume a substantially horizontal position and thus level the wheel-frame. The two bars 48 are permitted to 'be brought into alinement by reason of the fact that the openings through which the pivots 47 pass are in the form of slots, as indicated at 55.
