'To @ZZ whom, it may concern: l

seo, county df Henry, State of Illinois, have in- Vented a certain new and useful Improvement in Cultivators; and I declare the following Vto bea full, clear, and exact description of the v invention, such as will enable others skilled ments in 'connection with rotary,disk'cultivators; and the several improvements consist of acombinat-ion of devices and' appliances hereinafter described and claimed.

in the art to which .it pertains to make and Ause the same, reference being had to the accompanying drawings, which form a partofthis specification. My invention relates to certain improve- In, the drawings,'Figure-1 is a rear elevation of my cultivator. Fig. 2 is a plan View. Fig-'3 is a side elevation with parts removed. Fig. fi is a detail view of the shield. Fig. is a ldetail view of the shield-frame. Figs. 6, 7,

and 8 are views of the covering used on the shield. Fig. 9 is `a side elevation of the disk. Fig. l0` shows the manner of attaching the disk tothe standard. Figs. 11, 12,'and 13 are views of the standard and the parts used to attach the disk'.

yIn carrying out my invention, A represents the main axle, composed veither of wood or iron, o1; both, and having the `iron spindles B attached to the ends. Of course, if desired, the axle and spindles might be of one piece; but I prefer the construction shown.

C are the wheels, and' D the main frame. The latter may be either wood or iron, as desired. E E are ratchets secured on both sides of the frame, and pivoted thereto are the levers F F. These levers are connected by the chains G G with the disk-beams Q, whereby the latter may be raised and lowered at will. H represents the oprators seat supported by the bars I, which extend forward and are pivoted at fi, these bars resting in the rests J J', attached to the axle; or, if the operator desires, he may transfer his weight to the culti-- vater-disks. This is done by the means of the forked standard K, which,'being attach-ed to the cultivator-beams at 7c, extends up adjacent to the bars I, where it is provided with the "lt 7c' and spring 7a2. Thus by raising the seat and allowing 1t to bear on the spring k2 bythe bolt k the weight of the operator is. transferred to thedisk-beams. v

L L are arches connecting the disk-beams on either sideand madeadj ustable by di-viding them' and attaching them,v together by By providing a series of bolt-orifices the arches may be lengthened or shortened at will. I M are boxes attached to the disk-beams,

land in these boxes are held the standards N by' the bolts m. The standards are preferably s-haped as'shown in Fig. 10, with a journalbearing 'n at the lower end. Through this' bearing is passed the spool O, to which the disks P are attached by the bolts p, the end o of the spool being squared and entering the square orifice in the disk. Thesel bolts p extend from thedisks, Where they are held by the washer O', as in Fig. 12, through the spool and journal-bearing and secured by the nut p.l Thus the spool, with its disk, is free tofrevolve-in the journal-bearing 'nl It will be observed that the disks P are capable of being turned and secured in any desired position on these standards N. For instance, in Figs. l and 2 are shown the two forward disks facing outwardly, while the 8o The front half 8 5 eringZ, as shown in Figs. 6, 7, and 8, and the rear portion is formed of slats or bars R3.

4The object of this shield is to protect young plants from being buried or injured, and yet 9o allowing them by the .soil Working in small quantities through the bars R3 to cover them with enough new earthl to facilitate growth.

S is a clevis attached to the middle of the axle, and the pole X is attached thereto. The "95 draft is thus carried from the axle.

T is a lever pivoted to the pole in front of the frame and extending back adjacent to the seat, where'it is provided with the handle t. Pivoted to this lever and extending on each 'side lto the frame, where they are attached, .are the rods T.

By means of the leverand its rigid ,connections itwill be seen-that a change of .direction of the poleX or of the IDO rear end of the lever will correspondingly shift the line of travel of the cultivator-disks, and as the disks form the front bearing of the machine the direction of travel of the whole apparatus may be thus d-irected.

U V are braces extending from the diskbeams to the main frame and supportingthe former.

It will be observed that the upper end m of the standard where it enters the box M is made tapering, so that by means of the bolt 'm it can be drawn firmly to its seat, and yet by loosening the bolt the` disk can be readily set at any angle. So, also, by makingv the journal-bearing n at-an acute angle, as shown in Fig. 10, the disk when placed in position will have the upper half of its concave face in line with vthe standard-bearing, while the lower half will be thrown out, as shown.

- 1. In a cultivator, the combination, with the main frame, disk-beams and connecting mechanism, and the operators seat, of braces extending from the disk-beams to the seat and 'connected therewith by bolt k and spring 7a2, Y substantially as described.

2. In a rotary disk cultivator, the combina non, with tile-diskbem and disk, of the standard connecting them,` said standard having its journalbeardng for the disk inclined upward and outward tothrow the lower edge lever rigidly connected between its forward and rear ends to the4 disk-beams, substantially asv described.

4. In a rotary disk harrowfthe combination, with the frarne and the double row of fdisks carried thereby, of -an inverted-U shaped shield suspended between the two lows'of-disks, said shield formed with an imperforate forward, portion and. a'slatted rear portion, substantially as. described.

In testimony whereof I signthis specification in thepresence of two witnesses.

O. N. HUMPHRY, CHARLES J. HEFFLEY.
