IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 213,024, dated March 4, 1879; application filed September 20, 1878.

To all whom it may concern:

Be it known that '1, JOHN H. YAGER, of Jacksonborough, in the county of Butler and State of Ohio, have invented a new and Improved Harrow, of which the following is a specification In the accompanying drawings, Figure 1 represents a top view of my improved harrow Fig. 2, a rear view of the same; Fig. 3, a top view of the harrow with the sections arranged at an angle of inclination to the center; and Fig. 4 is a side view of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish for farming purposes an improved harrow the sections of which may be adjusted at any angle to the central axis and convenientlycarried to and from the fields; and the invention consists of two centrally-hinged harrowsections, which are made of toothed pieces that are pivoted to cross-bars, and adjusted at any suitable angle of inclination to the ion gitudinal axis by means of interlocking ratch ets and clamp-screws of the cross bars and pieces.

The harrow-sections are jointed by hingestraps of different length. The handles are applied to the barrow-sections by lockingratchets and clamp-screws, and maybe locked into position below the barrow-sections to serve as runners.

Referring to the drawings, A. A are two harrow-sections, which are connected by a central hinge-joint composed of rod 0 and hinged straps C, so as to fold one on the top of the other. Each harrow-sectionA is made in the customary manner of toothed pieces B, which are connected by pivot-bolts a to metallic cross-straps G. The cross-straps are firmly attached to the hinged straps C, of which the two front straps are shorter than the rear straps for the purpose of admitting the connection of the barrow-sections when adjusted symmetrically at an angle to the longitudinal axis, as shown in Fig. 3. The crossstraps O are bent up at their middle portions, and interlocking ratchet-wheels D, with radial teeth, interposed between the straps and the pivoted pieces B.

Through the straps, ratchets, and toothed pieces pass clamp-screws I), which, when loosened, disengage the ratchets, so that the pivoted pieces B may be set to any angle with the cross-straps.

By tightening the clamp screws 1), the toothed pieces are rigidly locked in the desired position, either at right angles or any other angle to the cross-straps.

The outermost toothed pieces B may be detached when it is desired to make the harrow smaller, as when changed to assume an angle of inclination to the center axis, as in Fig. 3. The outer pieces B are attached by separate straps O and by diagonal braces 0 so as to be firmly connected to the harrowsections.

The handles Eare attached by means of interlocking ratchets E and clamp-screws d to the rear ends of the pieces B. The harrowsections are controlled by the handles, which are then rigidly clamped in raised position thereto, as indicated in dotted lines in Fig. 4. By applying both harrows to one barrow-section, swinging the handles below the harrowsections, so that the eyes 0 of the bent-down rear ends engage teeth of the pieces B, and finally locking the handles firmly in this position by the ratchets and clampscrews, the handles serve as runners to convey both sections, one folded upon the other, to and from the place of work.

To the front part of the harrow-sections are 1. The harrow herein described, consisting, ably secured to the rear ends of the toothed essentially, of the hinged sections A A, combars B of one section of a hinged harrow by posed of toothed bars B, cross-straps O, interlocking ravtehets D, substantially as and hinged straps rod 0*, and interlocking for the purpose described.

ratchet-wheels D, as and for the purpose JOHN HENRY YAGER. specified. lVitnesses:
