HARROW.

SPECIFICATION forming part of Letters Patent No. 366,876, dated July 19, 1887.

Application filed May 9, 1887. Serial No. 237,586.

To aZZ whom it may concern:

Be it known that I, EDMUND RANKIN, J r., a citizen of the United States, residing at Lincoln, in the county of Logan and State of llli nois, have invented certain new and useful Improvements in Harrows, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in riding-harrows which are designed for pulverizing the soil, breaking up clods, and leveling the surface; and the nature of my invention is in the combination of cutting-teeth which can be set at different angles of inclination, both laterally and longitudinally, with clod-crushers and soil-levelers; also in a novel dumping device, as will be fully understood from the following description, taken in connection with the annexed drawings, in which- Figure 1 is a perspective view of my improved pulverizer and leveler complete. Fig. 2 is avertieal section taken longitudinally through the harrow on one side of the drivers seat. Fig. 3 is a perspective View in detail of part of one of the harrow-beams, showing the device for setting the teeth laterally at different angles for hillside and level-ground harrowing.

Referring to the annexed drawings by letters, A A designate two parallel beams rounded somewhat on their bottoms, and rigidly secured to two metal bars, 0 0, having front hooked ends, a a, for the attachment of a doubletree. The beams A A are arranged transversely with respect to the length of the harrow, and they are secured together at a suitable distance apart by means of longitudinal bars B B in addition to the longitudinal bars 0 O. The drivers seatD is mounted upon an arched spring support, D, the lower ends of which are secured to the two beams A A at or near the middle of the length thereof.

In front and rear of and between the two clod-crushing and soitleveling beams A A- (No model.)

cillated by the driver while in his seat, D. By means of slotted segments G, suitably notched, the driver can adjust the harrowteeth G and fix them at any desired angle forward or backward, or set them perpendicular to the plane of the top of the harrow.

Preferably the harrow-teeth are made with front draw-cutting edges, as shown in the annexed drawings, and their shanks h, which are flattened, pass freely through slots (1, made vertically through the harrow-beams E, which slots are oblong in a direction with the length of the said beams.

The barrow-teeth or cutting-blades G are attached to their beams by longitudinal fulcrurnpins i, and the upper ends of the shanks of the teeth G are pivoted to bars J, extending transversely across the harrow. These bars J are rigidly secured to angular standards L, which are attached to the harrowbeams by pins 17, inserted into holes 0. By these means the harrowteeth can be adjusted laterally and fixed at different angles for hillside or level harrowing.

S designates a horizontal transverse rod, which has its end bearings in raised portions b of the longitudinal bars B, and which is formed with backwardly-inclined arms 3 s, and also with fo0t-levers g g, which latter are convenient to the driver while in his seat, I).

The object of this lastdeseribed device is to enable the driver, by pressing with his feet upon the levers g g, to forcibly depress the arms 8 8 upon the ground and dump the liarrow, so as to free it of gathered trash.

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

1. Ariding-harrow consisting of the transverse elodcrushing and soil-leveling beams A A, the seat mounted thereon, the end bars, B, and connecting draw-bars O, the angular dumping-bar S, formed and adapted to oper ate as described, the oscillating teeth-beams E, levers for oscillating these beams, the notched segments G, and barrow-teeth which are pivoted to their beams and laterally adjustable, all substantially in the manner and for the purposes described.

2. The combination, in a ridingharrow, of ting these teeth vertically or at different anlongitudinstlly-oscillating beams E, the intergies, substantially as described. '10 mediate clod-crushing beams A A, harrow- In testimony whereof I aflix my signature in teeth whose shanks pass through slots through presence of two witnesses.
