HARROW.

SPECIFICATION forming part of Letters Patent No. 503,675, dated August 22, 1893.

Application filed August 5, 1892. Serial lilo-442,233. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES PERRIN, a cit-i zen of the United States, residing at Dayton, 1n the county of Montgomery and State .of Ohio, have invented certain new and useful Improvements in Rotary Disk Harrows, of which the following is a specification, reference being had therein to the accompanying drawings. This invention relates to new and useful improvements in harrows or cultivators of the class known as rotary disk harrows, and comprises a novel construction and arrangement of parts that will be hereinafter more fully set forth, and the essential features pointed out in the claims.

The object of my invention is to provide a harrow that is not only eminently adapted to all the ordinary work usually performed by this character of agricultural implements, but one that may also be employed with good results in the cultivation of corn and cotton.

A further object of my invention is to pro-v vide a harrow having each disk, independently of the rest, pivoted to the cross beam, byjmeans that will hereinafter be described. This enables the removal of one or more disks from the gangs, without interfering with, or necessitating the removal of others. Thus it will be seen that the number of disks may be increased or decreased according to the requirements of the soil under cultivation. Should it become necessary to straddle a row, the two inner disks may be easily detached from their pivots and removed from the gangs, and the intervening row left undisturbed by the operation of the harrow, or should the extent of soil be such as to require the use of a less number of disks than the entire gang, they may be removed from the outer or inner ends of the gangs. In arranging the disks to work independently of each other, other objects are accomplished; the bearing incident to the angling of the gangs is distributed among the entire series of disks. Each disk being pivoted to a cross beam,furnishes its own independent bearings and stands independently, the pressure thereof. Thus it will be seen, the necessity of having the entire bearings of the gangs, confined to a single shaft with the usual number of boxes and their standards to withstand the strain of the entire gangs, is avoided. In this individual attachment of the disks each disk is angled independently of the other, but all are subjected, simultaneously, to the same angle. The objectionable end thrust of the gangs, which greatly increases the strain on the two bearing points commonly found in disk barrows, by bringing the entire gangs with their frames, to an angle, is also avoided. By removing the cotters from the swivel connections the disks may be reversed and operated to throw the dirt in an opposite direction.

Reference is now made to the accompanying drawings and the detailed description to follow, in which other objects of the invention will appear.

Figure 1, is a View of the harrow from the rear, showing the disks at angle; Fig. 2, a plan view of the same; Fig. 3, a side elevation; Fig. 4:, a detached detailed view showing the angle bar and means by which the angling of the disks is effected; Fig. 5, a detached plan view of the outer end disk standard with arms for scraper bar and angle bar; Fig. 6, a side elevation of the same; Fig. 7, a detached plan view of the inner end of the disk standard, with arm for scraper bar, and arm for angle bar; Fig.8, a side elevation of the same; Fig. 9, a side elevation of a standard with arm for angle bar; Fig. 10, a plan view of the same; Fig. 11, a detailed sectional view of a pivot washer; Fig. 12, a plan View of the same. Fig. 13, is a sectional view of pivot washer, standard and disk.

In the views like letters of reference denote the same parts.

Letter A, indicates the tongue bolted and braced to the cross-beam B; to the under side of this cross-beam, is attached a series of pivot washers (a;) by means of counter-sunk bolts passing upwardly as shown in Figs. 11 and 12, through the cross-beam and made secure at the top thereof by nuts, or any other suitable means. i

0, represents a series of standards with forwardly extending parallel arms 0'. Four of these standards are also provided with back wardly extending arms D and D,tl1e standards and said arms being integral parts or one casting. These standards are provided ICO ceive the stud F, and become theretosecured by a cotter or other suitable means passing ter opening of the disk E, by being riveted.

thereto, and forms the box or bearing-for the disk. This washer in turn is adapted to rethrough the eye on the outer end of said sthd, and on the outside of the disk, thus, securing the same in an operative position. bars G and G6 are connected with the arms 0" of the disk standards by means oi bolts. The inner ends of these angle barsare-bolted to the angle disk or plate H, which is pivoted to the under side of the tongue A.

I and'l' are angle rods or levers having their outer ends pivoted in the angle bars G and G; the inner ends of thesereds are likewise pivoted to the angle disk as shown in Fig. 4. In this view the ends of the. anglerods; land I are shown as pivoted to the disk H,.in an oblique position to each other. In this position the. disks are straight. A red or lever J,'is pivoted at its inner end, to theangle disk H,and has its forward end ivoted to the lower end of the upright hand-lever P, as shown in Fig. 3. By throwing this lever,

the power is transmitted co the angle disk H,

and from thence to the angle bars G and G" by the rods I and l, and the disks simultae .neonsly angled and locked by means of the.

segment rack s, and locking bolt-t. The angle to which the disks may be adjusted, can be increased by enlarging the circumference of the angle disk, H; it being readily seen, that the larger this disk is, the greaterwi'll -be the angle to which the disks may be brought. The movement imparted by the lever- P, cornpols each and every disk "to effect the same angle. The backwardly extending parallel arins D and D" are designed as supports for.

the. scraper bars R. and R which are. adapted to slide back and .forth in adjusting the the scrapers u, to and from the, disks. I have,for the purpose of this specification, only shown two scrapers, but each disk; will be provided with one, their purpose being to free the sides of the disks from dirt during the operation of the machine.

The oblong apertures Q, ofthe arms D- and v D, are constructed so as to'allow the scraper bars R and R, to adjust themselves therein, when the disks are brought to an angle. The adjustment of these scrapers is effected by means of pedalsV andV', arranged in a convenient place for the driver to keep his feet; on one or the other during the working of the harrow.

I wish new to call attention to the inner arms D. It will be noted the angle arms of- The an gle feet a change of contour or a curve, not shown in the outward arm D. This construction is to enable them to work free of each other, when the disks are brought to an angle.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a disk barrow, the combination with the cross-beam, of a washer secured to the under side of said cross-beam, said washer i provided with a downwardly projecting pin, a standard provided with an integral torward- 1y extending arm, and an aperture adapted to 'j receive the pin of said washer, and thereupon and against said washer become adapted Z to vibrate on a pivotal point below said cross- Ebeam, by the action of the: angling bars G, E and G attached to theforwardly extending farms of the standard, substantially as de- 1 scribed.

j 2. In a disk harrow, the combination with gthecross-beam and a washer with a down- Rside of said cross-beam, of a standard pro.-

-; set at various angles, substantially asherein 3 described.

3-. In a disk-barrow, the combination with i the cross-beam, and the disk with washer fig) forming the box thereior, of a; standard with :forwardly extendingarni, the. angle. bars G, and G attached tosaid arm the. said standl ard also provided with a laterally projecting .stnd F, by means of which a bearing is atforded'the disk E, with the washer (9 sub 1 stant-ially as herein described. 4. The combination with the beam and the iwasher (a) with the downwardly projecting 2 pin (0), of the, standards 0, and, integral forwardly extending arm' O and the. laterallyiprojecting stud F, the disk E, with washer I (g), and the angle bars G, and G and the rods 1', and I pivoted to said angle bars, and the plate H, pivoted to the lever- P, by the bar J, substantially as herein described. 5, The combination with the cross-beam, thQW-ashers with downwardly'proj ecting pins, the disks and the standardsw-ith laterally projecting studs F, adapted to receive a sleeve washer (g) rigid-1 y attached to said disk and -comprising the hub thereof, the forwardly be rigidly attached to the bars'G, and, G Y which bars are in turn pivoted to the angle plate H, by the rods I, and I, and the plate H to the lever P, by the rod J, substantially as herein described. r

6. Ina disk barrow-,the combination with wardly projectingpimbolted to the under 7 vided with a forwardly extending arm inteextending arms or said standards, adapted to the cross-beam, and the washer (a) with downwardly projecting pin (0), said washer bolted to the under side of said cross-beam, the standards having forwardly projecting arms, and the standards having both forwardly and rearwardly projecting arms, all of which are provided with laterally projecting studs F, at their lower extremities, which studs afford bearings for the disks E,with washer (g), substantially as herein described. :0

In testimony whereof I afiix my signature in presence of two witnesses.
