SPECIFICATION forming part of Letters Patent No. 5Q8,481, dated November 14, 1893.

Application filed'J'anuary 9, 1893. Serial No. 457,843- .(No model.)

To all whom it may concern:

. Be it known that I, LUBPE LUPPEN, a citizen of the United States, residing atPekin, in the county of Tazewell and State of Illinois,

have invented certain new and useful Improvements in Cultivators, of which-the foldetail, bein a section on line 77 of Fig.4..

Fig. 8 is a plan view of the disk gangs showing them arranged for throwingthe dirt outward; and Fig. 9 is a rear view of the parts shown in Fig. 8.

My invention relates to cultivators, and particularly to disk cultivators.

' The objects of my invention-are to provide improved devices for mounting the disks,

. ends of the

spindles

23 and 24 with the ends whereby they may be easily adjusted to the lineof motion of the cultivatorfor the purpose of regulatingthe furrows; to provide means whereby the disks may be arranged for'throwing the dirt either in or out; to provide means whereby the depth of the fur-' rows may be regulated at pleasure, and to improve the construction of cultivators of this class in general. I accomplish these objects as hereinafter specified and as illustrated in the drawings.

That which I regard as new 'will be pointed out in the claims. I

1 wheel axle 12,

wheels

13 and 14, seat bars 15 and16, draft bar 17, and braces'18 and 19.

= The'draft bar 17'is mounted-upon the tongue 12 near its rear end in the usual manner, and I is provided with depending hangers 20 near its ends, as shown in Fig. 1. The braces 18 and 19 extend from opposite sides of the tongue 11 to the wheel axle 12, to whichthey are connected, as best shown inFig. 2, and

serve to brace the tongue. The

seat bars

15 and 16 are connected at their forward ends to the braces 18 and 19, and carry a seat'21 at their rear ends, as shownin Figs. 1 and 2.

22 indicates an arched axle which constitutes a front support for the frames of the disk gangs and is mounted upon the rear end of the tongue 11. and providedwith spindles 23 and24 located in front of and slightly'below the spindles of the

wheels

13 and 14, as

best shown in-Fig. l .25 and 26 indicate sleeves or pipe-boxes, mounted respectively upon the-

spindles

23 and 24, as shown in Fig. 2. Each pipe-boxis I provided with one or more bolt-holes 27, by means of which the cultivator couplings may be coupled to the pipe-boxes, as will be hereinafter described.

28'and' 29 indicate brace rods connected at their rear ends to the ends of the axle 22, and at their forward ends to the tongue 11, as shown in Fig. 2.

30 and 31 indicate draft rods, connected at their rear ends to the

spindles

23 and 24 and at their forward ends to the hangers 20, as

shown in Figs. 1 and 2.

32 and 33 indicate rods which'connectv the of the wheel axle 12, as best shown in Figs. 2 and 3. I I

" 34 and 35 indicate cultivator gangs,.which are mounted under the Wheel axle 12 and are connected at their forward ends to the pipeboxes 25 and26 byv means oficouplingsz36; as best shown in Figs. 1 and 4.- -"Each'coi1pling 36 consists of alink37,whichispivotally connected to one of the pipe-boxes 25 or 26: by

means of a bolt 38, which passes-throughbolt holesiii the forward'portion of the link and through one of the holes 27in the'pipe-box.

Rigidly connected to each link 37 is a footlever 39, which extends rearward therefrom substantially in a horizontal position, andis provided with a foot-rest 40, as shown in Fig. 1. The foot lever 39 is adj ustably secured upon its link-37, and for this purpose I prefor reuse a clutch 41 composed of two clutch; .95

sections adapted to be held tightly together by a bolt 42, as best shown 'inFig. 1. By

loosening the bolt 42 the position of the lever 'r 39 with reference to the link 37 maybe adjusted as desired. 1

Each

disk gang

34 and 35 consists of a frame IOC 43, having depending

arms

44 and 45, by

at one end of the rear portion thereof is a horizontal plate 47, as best shown in Fig. 5.

48 indicates a second plate, which is adapted to rest upon the plate 47, which plate 48 is provided with an upwardly projecting arm 49, as shown in Fig. 5. The

plates

47 and 48 are secured together and to the disk frames 43 by bolts 50, which pass through said plates and through bolt-holes 51 provided in the upper surface of the rear portion of the disk frames 43. A number of holes 51 are provided in the disk frames 43 to permit of adjusting the position of the

plates

47 and 48. The

plates

47 and 48 are adapted to turn upon each other to permit of the adjustment of the frames 43 to the line of motion of the cultivator.

52 indicates an arch, best shown in Fig. 3, which arch connects the arms 49 carried by the two disk frames 43, as best shown in Fig. 3. The lower ends of the arch 52 are secured to their respective arms 49 by bolts 53, in such manner as to permit of the turning of said arms upon the bolts 53 as their axes. Near the upper portions of the arms 49 are provided bolt holes 54 adapted to receive a pin 55 which is adapted to pass through the arch 52 into the holes 54 to permitof adjusting the angular position of the arms 49 to the arch 52, and thereby providing for the vertical adjustmentof the cultivating disks, as indicated by the dotted lines in Fig. 5.

The disk frames 43 are provided attheir forward ends with bolts 56 fitted in slots 57 in plates 58, in such manner that the disk frames 43 may be partially rotated on a horizontal axis without moving the plates 58. Each plate 58 is provided with bosses 59 and 60 adapted to receive a bolt 61, which passes through suitable holes in the rear portion of thelink 37, as shown in Fig. 1. By this construction lateral swinging of the disk frames 43 is permitted.

At some suitable point upon each disk frame 43 is provided a bracket 62, which is provided with a horizontal slot, as shown in Fig. 3, through which slot the lever 39 passes, as best shown in Fig. 3. Each bracket 62 is provided with bolt holes 63 arranged at suitable points on its upper surface, as shown in Fig. 3.

64 and 65 indicate levers for adjusting the height of the disk gangs. The

levers

64 and 65 are mounted at opposite sides of the cultivator frame, and each lever is connected through a rigid connecting rod 66 to the bracket which lies under it, by a bolt 67. By adjusting the point of connection of the rod 66 with the bracket 63 the action of the lifting lever may be varied.

68 indicates segmental racks adapted to receive pawls 69 carried by the

levers

64 and 65, for locking the levers in position.

By connecting the

levers

64 and 65 with the disk-carrying frames through the medium of rigid connecting rods 66, a positive downward pressure may be exerted upon the gangs separately, thereby forcing them into the ground, and by locking levers the disk gangs may be held at any desired depth. If it is desired to hold the gangs in the ground in an inclined position, the connecting rods 66 are connected to the brackets 62 at one end or the other, depending upon the direction of inclination in which the gangs are to be held. The arrangement described enables the entire weight of the machine and rider to be thrown upon the disk-carrying frames, thereby securing a very efficient machine.

The operation of the cultivator is as follows: When the cultivating disks 46 are not in use, the

levers

64 and 65 are thrown back, thereby lifting the disks from the earth, the pipeboxes 25 and 26 turning upon their

spindles

23 and 24 and thereby permitting of such lifting of the cultivating disks. For throwing the dirt in, the disks are arranged as shown in Fig. 2, and the extent to which they will throw the dirt in will be determined by their angle to the line of motion of the cultivator. By moving the foot lever 36 laterally the forward portion of the disk frames will be thrown in in the same direction in which the foot lever is moved, thereby throwing the forward edges of the disks also in a similar direction, as indicated by dotted lines in Fig. 4. By the peculiar arrangement of the coupling, devices by means of which the forward ends of the gangs are shifted to adjust the position of the disks, a much greater leverage is obtained and the foot levers are relieved from the greater portion of the strain upon the cultivating disks. The operator is thereby enabled to hold the foot lever at any desired position by a slight pressure of the foot. This permits of very accurate and rapid adjustment of the disks and facilitates the avoidance of obstructions. As the disks are adjusted to the'line of motion, the

plates

47 and 48 will turn upon each other as may be necessary. When it is desired to change the depth of the furrows so that they will not all be ofequal depth, the cultivating disks may be thrown int'b an inclined position by adjusting the angle of the arms 49 to the arch 52, as indicated by dotted lines in Fig. 5. Such rotation of the disk frames as may be necessary on account of such adjustment of the disks will be permitted by reason of the construction of the plates 58, as shown in Fig. 7. To arrange the disks for throwing the dirt outward, the

plates

47 and 48 are moved to the opposite ends of the disk frames 43, as shown in Figs. 8 and 9, and the

disk gangs

34 and 35 exchange places; that is, the gang 34 is moved to the left hand side of the machine, as shown in Fig. 3, and the gang 35 to the right hand side. Theparts will then be in the position shown in Figs. 8 and 9. By adjusting the position of the

plates

47 and 48 upon the disk frames 43, the action of the foot levers 39 may be varied to cause them to.

wish to limit .myselfto the-use ofdisks, as;

other suitable cultivating devices may. be

- used. Neither do I wish to limit;myself to the use of coupling linksof the specific construction shown,- as-otherdevices could be used to accomplish thesame result. The formshown, however, is the best known to me at;

present.

By constructing the cultivator as above described, it is particularly adapted for use in hard soil or in replanted corn, as without leaving his seat the operator may cause the dirt to bethrown high or low by means of the foot lever, and' the disks can be held in the ground at any desired depth while the cultivator is in motion, even though there may be hard parts and sandy soil in the same row.

A peculiar advantage lies in the fact that the operator can operate the disks by means of the foot lever to dodge corn,- at the same time leaving his hands freeto handle the lines.

1. The combination witha carriage, and a front support, of a laterally-movable disk frame, having a jointed connection atits front end with the said support, and a laterally-movable lever rigidly connected to said jointed connection, and serving to move the disk frame and the forward edges of the disks in the same direction in which the lever is moved, substantially as described. 7
