`Application filed July 12, 1905. Serial No. 269.375.

To ct/LZ whomI t indy concern;

l' Be it known that I, NATHANIEL S. Banaan, a citizen of the United States, residing at St. Joseph, county of Buchanan, State of Missouri, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure l is a side elevation. Fig. 2 is a front elevation; Fig. 3, a plan view of one half or section of the cultivator, Fi 4, a front elevation of one pair of ang e-iron brackets; Fig. 5, an end elevation of same 3 Fig. 6, a top plan of same. Fig. 7 is a vertical section cut longitudinally through center of horizontal arm 17 and through its attached parts; Fig. 8, a longitudinal section eut horizontally through the center of arm 17El and its attached parts. of one of the slidable collars mounted on the disk-carrying arm, and Fig. 10 a plan view of the collar shown in Fig. 9.

This invention relates to that class of cultivators adapted for simultaneously cultivating two rows of plants, the draft-animal walking between the rows. The cultivating means are carried by independent frames, which are connected to ether by a couplerbar, each of said frames eing loosely mounted on said coupler-bar and having a limited lateral movement to permit said frames to be properly adjusted to bring the cultivator means 1n pro er position to operate on the earth about t e plant. Each frame is provided at its forward end with transportingwheels which are adapted to follow the iurrows, the draft being connected to said furrow-wheels in such manner that it will require a strong lateral or sidewise strain of said draft in order to cause said wheels to leave the furrows.

One of the many objects of this invention is to improve the construction of this class of cultivators and to render them more eitieient in operation.

A further object of the invention is to provide improved means for adjusting the cultivator-disks vertically and laterally and also to provide means for simultaneously adjusting the disks and shovels vertically.

Other objects and advantages of the invention will appear hereinafter.

Referring to the various parts by numerals, 1 designates the coupler-bar, which, as shown in the drawings, consists of a broad Fig. 9 is a side elevation flat wooden beam or plank, which carries on its upper side midway its end the drivers seat 2. This seat is supported by the inclined bar 3 and the vertical tension-rod 4, said bars androd forming a truss to strengthen the coupler-har.

The cultivatin devices are carried in frames 5, one of W iich is loosely mounted on each end ol the coupler-bar. As these frames and their attached parts are exactly alike, I have shown only one in the drawin it being of course understood that a simir trarne is mounted on the other end of the coupler-bar. In Fig. 2, 5a designates the inner end of the frame that is mounted on the left-hand end of the coupler-bar. These frames each ,consist of a front horizontal bar 6, a corresponding rear bar 7, side bars 8, and intermediate bars 9, the bars 8 and Q being secured at their ends to the front and rear bars. The side bars are bent inward and the intermediate bars are bent outward, as shown in plan in Fig. 3, the central portion of said frames being secured together to form the double longitudinal bars 9a. The front and rear ends of the intermediate bars lie side by side at the longitudinal center of the trarne and are securely bolted to the front and rear bars. The side bars and the intermediate bars are preferably formed of metal bent to the proper form, so that the frame will be light and strong. Secured to the under side of the coupler-bar, near each end thereof and at a point substantially midway between the seat and the end of the bar, is a retaining-hail 10, whose forward and rear bars are parallel with the side edges of the coupler-bar and projected slightly beyond said ed res, as shown clearly in Fig. 3. The double ongitudinal frame-bars 9a are connected at their forward and rear ends by means oi short transverse bars 11, and to these bars at the transverse center of the frame are secured de iendin roller-carrying brackets 12 and 13, t e brac iets l2 carrying a roller 12a, which engages under the front bar oi the bail or keeper, and the bracket 13 carrying a long roller 13a, which supports the rear end oi said bail or keeper. By this means the end ot the coupler-bar is suported by the frame, and the frame has a imited movement along said bar, said movement being determined by the length of the front and rear bars of the bail or keeper.

On the forward bar of the frame, near each g end therof, two pairs of angle-iron brackets IOO IIO

14 are adjustably seeuredmone pair engaging the upper longitudinal ed es of said bar, the other pair engaging the ower longitudinal edge thereof. Each angle-iron is provided with a horizontal inward-extending flange 14a, which engages a horizontal surface of the bar, as shown clearly in F ig. 5, so that each angle-iron embraces one corner of said forward bar. Each iron 14 is also formed with parallel vertical ribs or flanges 14D, the flanges of one iron being directly in line with the corresponding ilanges of the adjoining angle-iron mounted on the same vertical side of the bar. Riveted to these angle-irons or brackets are depending wheel-supporting standa.rds,which consist of two parallel bars 15 and 16. One of these bars is secured to one of the brackets above the forward bar and to one of the brackets below said bar and lies between the ribs 14h, the other bein secured to the two brackets which engage t e other vertical side of the forward bar. By means of bolts 14, which pass through each pair of brackets, and the bars 15 and 16 above and. below the forward bar of the frame the wheel-standards are adjustably secured to said forward bar.

It will be readily seen that by loosening the bolts 14, brackets and the wheel-standards may be adjusted along the bar of the frame, to place the wheels carried thereby the proper distance from each other to adapt them to travel in the furrows. At the bottom of each of these standards is rigidly bolted an outward-extending rectangular horizontal bar 17, the inner end of cach of said bars eX- tending slightly beyond the inner edge of its standard and carrying at said inner end a tubular socket 18. Rotatably mounted in this socket is a vertical wheel-carrying bar 19, whose lower end is bent outward to form a horizontal spindle 20, on which is mounted the transporting-wheel 21, said wheel being secured on said spindle by means of a clip 22, which is secured in place by a bolt and is provided with an arm which is adapted to engage a collar on the wheel-hub. W'hen it is esired to remove the wheels from the s indles, the clips are raised to disen age their arms from the collars on the hu s of the wheels. Near the upper end of each of the wheel-standards is secured an inward and forward extendin f bracket 23, through which the upper end of the rotatable bar 19 extends, an adjustable collar 24 being secured to said bar above said socket. below the socket 18 is secured a collar 25, said collar preventing any independent upward movement of the bar 19. The collars 24 and 25 are secured to the bar 19 by means of set-screws 24a and 25a. The outer end of each of the arms 17 is extended vertically a short distance and is then carried back to the wheel-standard to form a horizontal cylindrical beam-carrying bar 17a, which lies directly above the bar 17, its inner end being To said bar ri V{fidly bolted between the two parts of the wheel-standard. Two collars 26 arc mounted on each of the rectangular arms 17, said collars being formed with rectangular' openings jto fit said arms. 'Ihese collars are formed with cylindrical reduced portions 26l on their outer sides and with the rearwardextending lugs 27, said lugs being provided with a series of perforations. rl`hese collars are split, and pinch-bolts 29HL secure them rigidly to the bar 17 in their adjusted position. Rotatably mounted on the reduced portion 26a of these collars are the arms 23 of a stirrup 29, said stirrup connecting the arms 23 below thc arm 17v The arms 2S are formed with rearward-extending lugs 23a, which are provided with perforations adapted to register with corresponding perforations in the lugs 27. The stirrup 29 is formed with a concave portion 30, which is serrated and is adapted to receive the serrated forward end of the tubular rearward-extending disk-carrying arm 31, said arm being secured in the stirrup by means of an eyebolt 32, which passes down through the stirrup and cncircles the diskarm. By means of the registering openings formed in the lugs .7 and 23a the inclination of the disk-carrying arm 31 may be varied to cause the cultivator-disks to work at the proper depth in the soil. A cultivator-disk 33 is secured to the rear end of each of the disk-carrying arms 31 by means of a journal-box 34, which may be of any suitable construction.

Pivotally mounted on each of the beanicarrying arms 17u are two clips 35, between the rear ends of which is bolted the forward end of the cultivator-beam 36. Clips 35 are adjustably kept in place on arms 17d by setscrewed collars 35a. Beam 36 carries at its rear end a shovel 37 of any suitable form. Secured to each of these cultivator-beams, on the outer side thereof, is a clip 38, which is formed with a flange 39, through which projects a rod 40. The lower end of this rod is connected to an eye 41, formed on the upper side of the adjacent arm 31, at the rear end thereof. Surrounding this rod and bearing against the under side of the flange 39 is a coiled spring 42, said spring being held against said flange by means of a collar 43, adjustably secured on said rod. Un the rod 40, above the flange 39, is adjustably secured a collar 44. By this means the cultivatorbeam and the adjoining disk-carrying arm are yieldably connected together, the spring 42 normally servin to keep them in their relative positions, But permitting them to approach each other when sufiicient strain is brought thereon in the roper direction to compress said s ring. T e cultivator-beams are very much onger than the disk-carrying arms and are bent inward at a oint sli Y htly in the rear of the axles of said isks to Bring the cultivator-shovels carried at their rear IOO IIO

ends directly in line with the furrow-wheels carried by the forward wheel-standards, as shown clearly in F i f. 3. rhe cultivatorbeams may be moved laterally on the arms 17 a, and the wheel-standards may be laterall adjusted on the front bar of the frame in or er to secure the proper relative positions of these parts.

In bearings 44a, secured to the under side of the frame at the rear end thereof, is mounted a transverse rock-shaft 45. On said shaft directly over each cultivator-beam is secured a downward and forward extendingr arm 46, which is connected by a link 47 to the cultivator-beam. On said rock-shaft is mounted an upward-extending arm 48, whose up er end is connected by a forward-extending ar 49 to the lower end of an adjusting-lever 50, said lever being pivoted upon a suitable support mounted on the top of the inner longitudinal bar 9a. This lever is provided with a rack and dog, by means of which it may be secured in any osition, the forward end of said lever exten ing into such a position that it may be conveniently grasped by the sperator. By these devices the cultivator-beams and the connected disk-carrying arms may be vertically adjusted to bring them into or out of operative position. lt will of course be' understood that when the disk-carrying arms are adjusted by means of the registering apertures in thc lugs 27 and 28 said arms are disconnected from the cultivator-beams.

On the rear bar of the frame, at each end thereof, are mounted angle-iron brackets 51, which correspond to the brackets 14, mounted to the front bar cf said frame, and to these brackets are secured the depending` wheelstandards 52. In the lower ends of these standards are secured the rear-wheel-carrying spindles 53, on which are mounted the rear transporting-wheels 54, said wheels being somewhat larger than the forward transporting wheels. These rear trans ortingwheels are cn the outer side of the ou tivatorbeams and the cultivator-disks and are ada ted to travel in the furrows made by sai disks. It will therefore be seen that the forward trans orting-wheels are arranged to travel in the oIld furrows, and the rear wheels are to travel in the new furrows made by the cultivator-disks, so that the machine will be self-guiding and each frame will follow the proper furrows and automatically laterally adjust itself in proper relation with the row ci plants to be cultivated. The lateral movement of the frames on the coupler-bar is limited of course, by the keeper or bail 10.

The collars 24 and `25 on the bar 19 are formed with forward-extending lugs, to which are secured the forward and upward extending guide rods or bars 55. Between the upper ends of these guide-rods and separately secured thereto are the circular plates 56, which are adjustably and pivotally secured to the upper and lower sides of the horizontal transverse draft-beam 5?' by bolts 58. The plates 56, and consequently arms 55 are adjustable along the draft-bar 57 by means of" a series of perforations in said draft-bar adapted to receive the securing-bolts 58. To the center of the draft-bar and midway between the arm 55 is secured a draft-clip 59. By this arrangement cf thedraft-connecting devices the strain of the draft-bar 57 will tend to hold the wheels 21 in the furrows, so that any strain or thrust on the wheels tending to dclect them will be resisted to the extent of the forward strain on the draft-bar 57 and also by the connected wheel 21, as both wheels must swing simultaneously.

The frame is braced by the truss-rods 60, which are secured to the lower ends ofthe forward-wheel standards, then ass over and are secured to the transverse rame-bars 11, their rear ends being,r connected to the lower ends of the rear-wheel standards. The frame is further braced by means of the rods 61, whose. forward ends are secured to the vertical bars which connect the outer ends of the bars 17 and 17, the rear ends of these bars being eonnec ted to the upper ends of the rear-wheel standards, as shown very clearly in Figs. 1 and 2 of the drawinvs.

From the foregoing it willlbe readil seen that l provide a cultivator of a very lig t but strong construction, wherein the sections carrying the cultivating means may automatically adjust themselves to the furrows alone' the rcw's of plants to be cultivated. lt will further be seen that while the cultivatorbeams and the disk-carrying arms are connected together and are adapetd to be. simultaneously adjusted by nieans of the levers 50, the spring 42 will permit the disk-arms to have an upward movement independent of the oultivator-bcams to permit the disk to pass over small obstructions without elevatmg the cultivator-shovel. It will further be seen that the transporting-wheels may be adjusted to travel at the proper distance on each side of the rows of plants to be cultivated.

It will be readily understood that the previously-made lurrows along the rows of plants will act as guides for the front furrow-wheels. For the safety cf the plants between said furrows and to prevent them being destroyed by the cultivatcr it is essential that said front wheels shall be guided by the previously-made furrows, and thus fallow the rows of plants whether these rows be in a straight or deviating line. lt is essential that this furrow-guidance of the front wheels shall not he overcome by any ordinary strain of the draft, and for that reason the pivotal attachment ci' the draft-beam 57 must not bo so 'far forward of the pivot-bars 19 as to produce too great a leverage in favor of the draft and against the furrow-guidance. lt will of IIO course be understood that it is essential that the guide-rods shall be ol snll'icient length to hold the forward furrowwheels in proper position and to prevent them being rotated on their pivots by slight inequalities in the furrows.
