cumivnron.

To ell whom it may concern Be it known that I, THOMAS S. .Wanivnn, a citizen of the United States of America, and

resident of Springfield, Ohio, have invented example, by my improved lister cultivator,

a certain new and useful Improvement in Cultivators, of which the following is a specificatio My invention relates to what are commonly known as lister cultivators-that is to say, machines adapted to cultivating corn that ha been planted in trenches by means of a lister. The prior art is exemplified, to

some extent at least, in PatentNo. 701,972.

My present invention contemplatescertain improvements on the lister cultivator of the general type disclosed 1n said patent. For

them from the in-throw to the out-throw with or. without interchanging them and with or without disengaging them from their mountings or bearings. This Ifind to be of considerable advantage, as it simplifies and :lacilitatesthe operation of changing the disks from the iii-throw tothe out-throw, or from the out-throw to the iii-throw, according to the requirements of the work for which a cultivatorof thisparticular character designed. rigainl provide improved means for varying the angularity and slant of the cultivator disks, whereby such adjustment can be accomplished readily and according to the character of the work. Also, by my improved construction, I providemeans for raising and lowering the cultivator disks independently of the shovels, as well as means for raising and lowering the shovels independently of the disks. As

" will hereafter more fully appear, however, andby reason ofa toggle-llke connection beit tween the wheelsand frameyof the cultivator, the, raising of the cultivator disks tends also togive the entire cultivator, except the Specification of Letters Patent. Patented Aug, 25, Application filed October 31, 1908. Serial No. 460,417. r 1

wheels of course, a slight bodily an or upward motion and at the same time tovary the balance, thus relieving the neck weight J of the pole.

I provide a couple of hand levershavinglan interlocking connection between them, whereby the raising and lowering of the shovels can be made to accompanythe rais-I ing and lowering of the disksby simply grasping and operating the lever which is allotted to the said disks. With this arrangement, I find that the control ofthe cultivator in the field is greatly facilitated and improved. 1

Still another featureof improvement con sists in the provision. ofha so-called hard As still another feature of improvement,

oiler for the cultivator disks, which disks 1 are arranged for instantaneous adjustment. from the' nrthrow and out-throw, and vice versa, as previously explained.

my invention consists in matters hereinafter set forth and claimed and illustrated inthe vention, the cultivator disks and shovels bein shown. resting on the ground. Fig. 2 a similar:view showing the disks and shovels raised from the ground. Fig. 3 is a plan. of the said lister cultivator, it being ob served thatthe disks and shovels are set for the in-throw. Fig. 4 is a rear view of the said lister cultivator, showing the plank or connecting beam which is employed for con v nectmg such cultivator wlth another similar cultlvator, 1t :belng understood that these cultivators are usually employed in .pairs, one being left-l1anded and the other righthanded, and that the driver occupies the seat which is supported on the said plank To the foregoing, andother usefulends,

or connecting beam on the point midwaybetween the two cultivators, thus bringingthe driver into a position to manipulate the hand-levers of both cultivators. Fig. 5 1s an enlargeddetail view of one ofthe mountlugs for the wheel and diskon one side of.

the cultivator. Fig. 6 is an enlarged detail 105. view illustratlng the construction for changin the horizontal an 'ularit or slant of one b b u of the disks. Fig. 7 is an enlarged sectional view of one of the dlsks showing the improved hard oiler forthe same. .Elg. 8 is an 11o enlarged CITOSS SQCtIOD .onthehne 8--8 of i Fig. 7. Fig. 9 is an enlarged section longitudinally of the squared shaft upon which the shovels are mounted, and which carries the arms or lifting connections by which the disks are raised andlowered. Fig. is a detail perspective view of the portion of the said square shaft showing means by which the arm is operated to raise and lower the shovel, and showing a portion of the arm which is loose on said shaft and by which the disks are raised and lowered. Fig. 11- is a detail view showing the squared shaft in cross section and showing the bearing in which the same is adapted to turn or rock.v Fig. 12 is a detail view showing the bottom of one of the'clamps or mountings by which the shovel beams are secured to' the said squared shaft which latteris in the nature of a rock shaft. Fig. 13 is aview .similar to Fig. 3, but showing the disks and shovels reversed or adjusted in a position for the out-throw that is to say, the adjustment by which the disks throw the oirt outwardly rather than inwardly.

' As" thus illustrated, my invention coin-- prises a tongue A, to which are rigidly secured the side members 'or frame bars B. A transverse axle G is mounted in suitable bearings on said tongue and side bars, and a squared rock shaft D is mounted in the bearings secured to the ends of said bars B. The disk-like wheels E are mounted upon the lower ends of the spindles or arms 6, and the latter have their upper ends hung in swinging castings or arms 6 which latter in turn hung on the said aXle C. The said castings are provided with bifurcated upper endportions between which are arranged the bearings e by which the said axle is supported on the frame. v With this arrangement the castings or swinging arms 6 can be moved toward and away from each other on the said axle. In order to hold the saidcastings or arms in dif erent positions on the said axle theupper ends of the same are provided with openings 6 adapted to receive the collars e" which are secured on the aXle with set screws 6 In this way the said castings or: arms 6 are held against movement toward and away from each other, and at the same time left free to swing upon the said axle;- Brace rods 6 connect the lower ends of the wheel spindles 6 with the tongue A, so as to'hold the wheels in position to support the tongue and frame and other parts in asuitab'ly'elevated position. Itwill be seen that the spindles e and thecastings or arms e -are pivotally connected in sucn manner that each wheel spindle and its allotted casting form a toggle joint connection between the culti vator frame or body and the supporting wheel E.

The angularly disposed cultivator disks F' are mounted upon spindles which are rotatably carr ed or inserted in the lower end portions f the castings 6 It will be seen that eaclrspindle consists of a lower end secticn f and an upper section P, the two sections being pivotally connected together by a bolt f and a collar f*, which latter is clamped on the spindle section f Another collar f is clamped onthe section f and this collar is connected with the spindle section 1 by means of a rod f". In this way the angular relation of the two sect-ions can be changed or varied as shown in Fig. 6,by sliding" the collar f back and forth on'the spindle section f. This, offcourse, will change the horizontal angularity of the cultivator disks, so that they may work according to different requirements. 1 In order that each disk may be oiled by hard oil or grease, these spindle sections f are preferablyprovided with a longitudinal groove f and the end is threaded to receivea threaded grease cap The sleeve f of the disk extends for some disengages from the threaded portion of the hub f, as shownin F 1g. 7. This leaves the disk in position to turn freely, and the caps The hub f of the Thus when the cap f gis screwed in f of the two disks are held against turning by the supports or'brace rods f. f are loosely'mounted on the rock shaft D and connected together by a bar f to which the upper ends of the rods f are suitably secured. rin arch or arm 1"" connects the bar f with the rock shaft D,'being loosely mounted on the latter. Theshovels G are secured to beams 51, which latter are rigidly secured near the. outer ends of the rock shaft D, in such a way as to allow a lateral adjustment, by means of which the d1stance between the shovels can be varied. Preferably,'the said shovel beams g are secured to the rock shaft by means of clips 9 which latter have 'c' rossgrooves 1 adapted to be engaged by theend portions of said shovel beams, insuch' a way that a forward or backward adjustment fof the beam will give Thearms a lateral adjustn ient to the shovel. In F i 3 it will be seen that these shovel beams converge toward the rock shaft, while in Fig. 13 the said shovel'beams converge rearwardly.

These shovelbeams are interchangeable, and

it is the crossed grooves g? which accommodate the sa d beams 1n their different positions on the bottom of said clips. In this way the shovels can be made to trail behind the cultivator disks in the usual manner, and for the well known purposes, re ardlessof the distance between the said disks. In Fig. 3 the disks and shovels are set forithe inthrow while in Fig. 13 the same are setfor whee the out-throw. In Fig. 13 the rods f are shiftedinto engagement with the bracket f located centrally of the bar f. In this way the disks are supported in either position and the change is made by simply swinging the disks over from one position to the other, the spindle of each disk being rotatably mounted in one of the castings 0 Any suitable means can be employed for holding the spindles 0f the disks against endwise displacement in the bearings The wheel spindles e are held against displacement from the said castings by means of collars c secured to said spindles and held inplace by setscrews 6 said castings being each provided with a cavity or opening 6 to accommodate said collar, as shown in Fig. 5. The brace rods H have their forward ends pivotallyconnected with the castings a and their rear-ends pivotally connected with the brackets it carried by the arms f. In this way the raising and lowering of the arms f not only tends to raise the cultivator disks f, but also tends to manipulate the toggle connections between the wheels E and the frame of the cultivator, thus slightly raising the said frame on the said wheels when the disks are raised from the ground and shifting the is under the cultivator, thereby changingthe balance. i

,In order to rock the rock shaft ,1) and thereby raise and lower the shovels G, the said shaft is provided witlran arm I, which latter is connected by a rod t with a hand lever '5 On this rod there is a loose sleeve which is secured to the said arm I and which is prevented from sliding oil the end of the rod bythe pin 2'. A collar 2' is secured to the said rod, and a spring 15 is interposed between this collar 1 and the sleeve In this way the shovels are yieldingly held in the ground, and are free to yield to obstructions and rise against the pressure of said spring. The said hand lever 71 is provided with asuitable hand operated latch or locking device adapted to engage a rack or segnent J which is secured to a second hand lever j. This second hand lever is in turn provided with an ordinary hand operated latch or locking device adapted to engage a stationary rack or segment j which latter is mounted on the tongue o-tthe cultivator.

It will be understood that both hand levers are suitably pivoted at. their lower ends so I that they may be swung forward and back by the driver or operator whooccupies the seat K. A red F connects the lever j with the arm or arch f, so as to raise and lower the shovels G and disks F when the two hand levers are locked together. It will be seen, however, that the hand lever i can be operated independently of the other lever forthe purpose of raising and lowering, the shovels independently of the disks. On the other hand if necessary, the hand lever i can be held stationary while the other lever is manipulated tochange the positions. of the it Will be seen that the two hand levers are inclined to the right, so as to be within reach of the driver occupying the scat K. This seat, it will be seen, is mounted on the cross plank or beam d? which extends from one cultivator to the other, it being common practice to employ these cultlvators in pairs.

The cultivator shown, is a left-hand Ina- Cl1ll'1t3,{t11l the plank or beam would eX- tend over to the right hand cultivator, the hand levers of which latter would incline to the left and thus be within reach of the driver. "It is a matter.ofconimon knowledge that in using a cultivator of this particular type it is desirable at one time to have the disks set tor an iii-throw oi the end, while 75 i from the ground. By referring to Fig. 4t

at other times and for another part of the general work of this particular kind of cultivating it isdcsirable tohave the said disks set for an out-throw Off are soil. as pre viously explained, my improved cultivator disks are adjustable from the iii-throw to the out-throw, simply byswinging each disk over fromone position to the other. The

shovels which trail behind the disks are always, of course, adjusted according to the distance between the disks, and this is done by interchanging the shovel beams, as pro. viously explained. It is evident that the said shovel beams can be interchanged, and thus shifted from one clip to the other. On the other hand, the clips themselves can be loosened. in order to take oil the shovel beams and the beams With their clips still attached can then be interchanged so that the clips are transferred from one end to the other of the rock shaft 1) upon which they are mounted, Thus considerable latitudeof adjustment is given for allfpurposes; and in each oz se the adjustment or change is eil'ected quickly and by exceediitigly simple and eil'ective means. construction of the cultivator isboth strong and light, and the parts are well balanced At the sanie tiinc the its llli i with respect to the dillierent strains to which the cultivator is subject while in use.

1th further respect to the changing oi.

the disks from the in-throw to the outthrow,

and vice 'versa, 1t Wlll be seen. that such adjustment can be ttCClJiIlPliSllGCl by interchang 7 ing the disks and their jointedspindles that is to say, by :trans'terring one entire spindle and its disk itroin one castingc" to the other casing 0 For certain require Cri ments and in some situations, this may be found desirable, although for ordinary purposes the disks are changed from one position to the other by simply swinging them over, and without removing their spindles from the said castings. In any event, however, the disk spindles are preferably supported by hanger rods or braces f, as explained, and these braces or hanger rods may be applied in various ways without de- This can be done, as stated, by either interchanging the spindles, or by rotating the same in their bearings on the lower ends of the castings 0 according to. requirements. The constructioncan of course, be changed. or modified more or less in order to accomplish these and other similar methods of adjustment without departing from the spirit of my invention. As shown, the hangers or brace rods f are secured at their lower ends to the caps f by means of threads, in such a way that the braces can be made shorter or longer thus changing the vertical angle or slant of the disks, and thus preventt 1e latter from turning and hold the disksrigidly to their work. V iththis arrangement the said hangers or brace rods are in the rear of the disks, but it is obvious that they may be otherwise located, relative to the disks. For this reason I do not limit myself to the exact construction of arrangement shown and described. At their upper ends the hangers or brace rods i are secured to the cross bar f, in one of several positions, by means of a series of holes, thus securing ad ditional adjustment for depth of disks. l Vhat I claim as my invention is:
