To all whom it may concern:

Be it known that l, WILLIAM S. GRAHAMM a citizen of the United States, and a r dent of Canton, in the county of Fulton and State of Illinois, have invented certain new and useful Improvements in Lister-Flows, of which the following is a specification, reference being had to the accompanying drawmgs.

This invention relates to improvements in lister-plows and has for its object to provide means capableof being readily applied to an ordinary plow of that character Whereby the machine is more perfectly adapted for the operation of double listing. By double listing is meant, the bursting out of previously formed ridges. between successive furrows that are spaced the usual distance apart, and forming in place of such, ridges additional furrows or trenches for the reception of additional rows 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; is put in better shape for cultivating; absorbs excessive moisture better; the deposited seed is not so liable to be washed out, and the roots of the plants are given a better chanceto extend themselves all of which results in a larger yield. While these various advantages are quite generally recognized the operation of double listing is frequently not resorted to owing to the difficulty of properly forming the additional furrows or trenches midway of adjacent furrows or trenches that have been formed the distance apart that is customary in ordinary single listing. That the difficulty is a very considerable one will be appreciated when it is borne in mind that the earth thrown upon these spaces intermediate of the first formed set of furrows is loose, ridge-like and considerable in quantity. Hence, the making of the desiredfurrows or trenches in such spaces necessitates skill and extreme care on the part of the operator of the machine in driving his horses, and that, too, even where one of the first-made furrows is utilized, as is generally the case, as a guiding track for one of the supporting Wheels of the machine to run in.

By the use of my improvements, ll am able to equip an ordinary wide-tread specification of Letters Patent. Application filed January 2, me. serial No. Wfltt.

Patented a a. far.

listeras machines of the general type shown 1n the accompanying drawings are generally termed-with means for efi'ec- .tively holding the plow-body'in a central position with respect to the intermediate ridged strip of ground being plowed. Such guiding and holdmg means and the manner of their adjustable and detachable connection with the machine are illustrated in the drawings and hereinafter particularly described. That which ll believe to be new will be pointed out in the claims.

In the drawings,

Figure l is a top or plan view of a widetread lister plow with plied thereto;

Fig. 2' is a side view of the machine as shown in Fig. 1, but with one of the supporting wheels removed therefrom for the sake of clearness of illustration;

Fig. 3 is a view in perspective of one of the guide-runners and. the means for securing it in place upon a wheel-axle, a portion of the wheel-axle to which it is connected being shown also;

Fig. 'is a detail, being a central vertical section through the guide-runner attaching means shown in Fig. 3, and showing in elevation a portion of the guide-runner and the wheel-axle with which it is connected;

Referring to the several figures of the drawings in which corresponding parts are indicated by the same reference characters,

10 indicates a frame member, to the side the drivers seat. Caster wheels 17 are provided at the rear end of the machine. 18 indicates a rock-shaft in the form of a bail my improvements ap-' 12 is suitably tltl lit

lltlh horizontal portions of crank-axles 25. These axle members are suitably journaled in place and each is provided on its inner. end w1th a crank ortion. Through suitable means said cra lever 26, through the operation of which the supportm wheels can be given the deslred relative a justment to maintain the frame substantially horizontal when one of the supporting wheels runs in a furrow while the other runs upon unplowed ground. The means referred to, as well as the other parts so far referred to by reference numerals,

' need not be here more particularly described,

as by themselves they form no part of my present invention, and indeed, so far as my present invention is concerned may be quite widely varied from. For a detailed description of the construction and operation of all such parts reference is here made to Letters Patent No. 1,249,067, granted on the fourth day of December, 1917, upon an application filed byme. As in said patent, the turning of the plow-bail 18 to raise and lowerthe plow-body is eife'ctedthrough a hand-lever,

here indicated by the numeral 27.

Turning now to those features which the resent invention particularly relates to,-28 indicates. a bracket that comprises, in the construction shown, .a horizontal arm 29, a

vertical arm 30, and a diagonal brace member 31 extending between said arms 29 and 30-said bracket parts being preferably formed integral with each other, as shown. Against the face of the vertical arm 30, and preferably in a shallow recess formed therein as clearly indicated in Figs. 3 and 4, rests the upper end of a guiding device'in the form of a runner 32 which is firmly held to the bracket by bolts 33 as shown, or otherwise. As shown, this runner is curved rearwardly and it is beveled as at 34 to provide a comparatively sharp or cutting edge alon its lower margin, the purpose of which wi be hereinafter described. There are two of these guide-runners and attaching brackets,

one for each side of the machine, and each is securedin place by exactly the samemeans. Such means comprise a bracket 28 for attachment to one of the axle members 25 and a link for connecting the bracket to one end of the plow-bail 18. Referring to the bracket therefor.

s are connected with an operating connection to its axle member, it will be noted that at one end, and substantially in line with the vertical arm 30, rise two short walls 35 between which the axle member extends. These walls'form a support for a block 36 that is suitably shaped to partially surround the axle and constitute a hearing The block is removably held in place by a bolt passed through one of the walls 35 as shown in Fig. 3, and also b inwardly-turned flanges at the upper en 5 of said walls. By removing the bolt the bearing block can be moved laterally to disengage it from the retaining walls.- The upper face of the member 29 of the bracket is to be curved to fit the axle-member and thus form an extended and properly-shaped bearing between the bracket and its axle member. At the outer end of the bracket and on its under face is provided a semi-circular rib 37. 38 indicates a block roperly curved to fit against the axle mem er 25 and located adjacent to the inner end of the bracket. This block is provided with a lateral extension or flange 38 that is so shaped as to provide a groove or channel adapted to receive the said rib 37. 39 indicates a shackle passing over the axle member 25 and having its ends passed through opposite ends of the said block 38; By means of nuts 40 screwed tightly on the screw-threaded ends of the shackle the block 38 can be securel clamped to the axle member and,.while per ectly supporting one end of the bracket in place and holding it against movement longitudinally of the axle by reason of the enga gemcnt with the rib 37, yet permit a free swing of the bracket on the axle when the guide-runner is adjusted as hereinafter described.

The bracket-attaching link hereinbefore referredto is indicated by 41. It is connected to the bracket by having its lower end turned to loosely enter a hole 42 in an car 43 formed on the rear edge of the bracket and near the lower end thereof. From the bracket the link extends upwardly and to the rear and its upper end is screw-threaded and engaged in a screw-threaded head 44 from one face of which projects a cylindrical laterally-extending stud 45. 46 indicates a lock-nut on the link for holding it in any desired position with respect to said head 44. 47 indicates a short crank secured by a set-screw, or otherwise, to an end portion of the plow-bail 18, and through an opening in the end of the crank projects the cylindrical stud 45, it being held in place by a cotter-pin as shown in Fig. 1, or in any other suitable manner.

Aftera field has been plowed as in singlelisting and a series of parallel furrows or trenches formed that are the usual distance apart, if it be then desired to do double-listing,that is, form a furrow or trench betweenadjacent furrows or trenches that all ,of the furrows or trenches a.

navnoar have been formed-two runners 32 are at tached by means of the brackets 28 to the respective axle members 25. They are adjusted alon the axle members so as to have them equidistant from the plow-beam and so that when the plow-body is in position to plow centrally of the space between adjacent single-listing furrows or trenches they will be, respectively, but a short distance from the inner walls of the two adjacent furrows or trenches between-which the double-listing furrow is made. When adjusted to pro er position they are then secured there y clamping theblocks 38 to the axle members as above described. The turned ends of the links 41 are then inserted respectively in the openings 42 of the ears 43, e links havin previously been adjusted as necessar wit respect to the heads 44: by turning t em in the screw-threaded openings 1n such heads. The links can be placed so that their turned ends enter the eyes from either side of the ears 4E3,Fig. 1 showing them entering from one side and Fig. 5 from the other side. Being able to attach them in eitherpne of these two positions facilitates adyustlng the brackets along their respective axle members to bring the runners to correct position in relation to the Walls of the furrows or trenches. As no great range ofadjustability of the runners is required owing to the quite uniform distance apart that prevails in the making of furrows or trenches in lister plowing, the adjustment that can be had by connecting the links to the brackets in one or the other of these two ways is ordinarily all the provision that need be made therefor, but if a little further adjustment should be required it can be had by shiftlng the cranks nearer to or farther from the ends of the plow-bail, as will be understood.

In Fig. 5 there are shown several furrows or trenches that have been formed, a a, indicating those that have been formed in single-listing and b, 6, indicating those formed in the operation of double-listing,- the plow-body 20 being in one of and the runners in guiding position in two When the plow-body and the guiding devices are so located one of the supporting wheels 23 will also travel in another previously-formed furrow, thus utilizing three such furrows as guides during the making of a double-listing furrow. With the parts in o erative position as indicated in said Fig. 5, t e runners being positioned close to the walls of the space being plowed will act not only as a guide for v the central plowing of that space but will act as guards to counteract any tendency of the plow to turn toward either side of such space, stron and, without such guardin means, very ifficult to overcome owing to t e quantity of loose dirt thrown on said space durbe readiity the latter which tendency is ordinarily very till ing the makin of the first series of furrows or trenches. cure of such loose dirt is almost always present also in the previously made furrows or trenches and it'is, therefore, desirable to make the curved edges of the runners comparatively sharp so that may more easily pass therethrough. 'lhls sharpened edge is provided by beveling as at 34:, the bevel being at that side of the runner that comes next to the wall of the central space being plowed and therefore preventing the runner from readily gouging into such wall when forced against it. I At the end of each furrow, the plow-body will be raised of course by swinging the bad 18 to which the plow-beam is attached, such movement being accomplished through the lever 27. The rocking of the hail of course turns the crank-arms 47 that are fast on its ends and thereby each runner 32 is, through its link ill, turned backwardl and upwardly, this being permitted t rough the journaling of the brackets 28 on their respectlve axle members 25. Thus, it will be seen, at each raising or lowering of the plow-body the guiding and guarding fenders will likewise be moved automatically. By my invention l provide means that can and easily attached to an ordinary plow o the type mentioned without so) changing or disturbing any of the parts thereof as to interfere with its working in the making of single listing furrows or trenches and that when applied will greatly lessen the labor and dificulties attendant upon double listing. While it have shown and described my invention in connection with a particular style of lister low it is of course understood that it is capable of application to other styles or makes of lister plows.
