HARROW.

SPECIFICATION forming part of Letters Patent No. 433,204, dated July 29, 1890. Application filed April 2, 1890. Serial'No. 346,338. (No model.)

To all whom t may concern:

Beit known that I, EDWARD R. JEwELL, a

citizen of the United States, residing at Weeping Vater, in the county of Cass and State of Nebraska, have invented a new and useful Harrow, of which the following is a specification.

This invention has relation to harrows of that class employing a series of sections, and among the objects in view are to provide means for so connecting the harrows that while not destroying their' independent movement, so advantageous, yet will compel them to move in unison and in substantially parallelism with each other, regardless of the fact of a greater amount of draft being applied to one end of the draft-bar than to the other, as caused by an uneven pulling of the team.

lVith the above general objects in View the invention consists in certain features of construction hereinafter speciiied, and particularly pointed out inthe claims.

Referring to the drawings, Figure 1 is a perspective of a harrow constructed in accordance with my invention. Fig. 2 is a central vertical section. Fig. 3 is a detail in perspective of one of the U-shaped standards.

Like numerals of reference indicate like parts in all the figures of the drawings.

Each of the harrow-sections 1 consists of opposite harrow beams or bars 2, provided with any usual number and character of teeth 3, projecting below the same. The forward ends of the beams are connected by an arched strap 4, the extremities of which are pivoted, as at 5, to the beams. The rear ends of the beams each have mounted thereon are formed of bar-iron bent intermediate their terminals or at their upper ends to form horizontal elongated eyes or slots 11. 12 represents a connecting rod or bar, which passes through the entire series of slots or eyes, and therefore extends transversely over each of the harrow-sections, the ends of the rod or bar being bent, as at 13, to prevent accidental withdrawal and also to limit the movement laterally of the harrows. Stops 14 are mounted upon the rod at the outside of the two central standards to serve a similar purpose as the bent ends.

The barrow-beams near their front ends and at their outer sides are provided with eyes 15, each barrow-section therefore having a pair of such eyes, and in each pair of eyes there is journaled a U-shaped draft-bail, provided at its forward end with a loop 16, engaging a staple 17, formed upon the rear side of a transverse draft-bar 1S.

From the above construction it will be apparent that, regardless of the unevenness of the draft as applied to either end of the draftbar, the barrow-sections will be maintained in substantial parallelism by the transverse connecting-rod herein described, and that at the same time the individuality of each harrow-section, as regards its independent movement, is not in the least interfered with, and a perfect freedom to that extent advantageous is preserved.

The rear ends of the barrow-beam have substituted for ordinary teeth cultivating-shovels 19, which are secured in position by means of eye bolts 20, mounted removably in transverse openings 21, formed in the beams and bound in position by means of nuts 22. These bolts are reversible, so that the shovel can be located at either side of its beam, and may be turned laterally so as to throw the dirt either to or from the corn. By arranging the beams in parallelism by the rear adjustment the same are designed to form the ordinary functions of the well-known and commonlyconstructed harrow, it being thus adapted for harrowing all kinds of ground.

Having thus described my invention, what I claim is 1. The combination, with a series of harrow-sections, of inverted-U -shaped standards mounted upon the beams of each of said sec- IOO tions and having' their upper ends provided With elongated horizontal eyes, and a connecting-rod extending' transversely over the standards and passing through the eyes and terminating in stops, substantially as speciied.

2. The combination, with a series of liarroW-seetions eonneeted at their front ends to a common draft-bar, of inverted-U-shaped standards mounted upon the beams of eaeh of the sections and having their upper ends bent to form horizontal elongated eyes, a

transverse rod passing through the series of eyes and having its ends bent to form stops, and stops mounted upon the rod at each side of the standards of eaeh intermediate section, substantially as speeied.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.

EDVARD R. JEVELL.
