SPECIFICATION forming part of Reissued Letters Patent No. 10.893. dated January 10,1688.

Original No. 346,266, dated Julyfz'l, 1886. Application fol-reissue filed November 2 8, 1881'. Serial No. 256,362. r

To. all whom it may concern.-

Be it known that I, J. MoRRIs CHILDS, of Utica, in the county of Oneida and State of New York, have invented certain new and use ful Improvemeutsin Harrows; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make anduse the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to an'improvement in represents a perspective view of'myiinproved' barrow. Fig. 2 .is a side view of a springtooth, aside view ofa section of the crossbeam, and a cross-section of an angle draftbar. Fig. 3 is a plan view of the reversible clip, which can be used on either half of the barrow. Fig. 4 is. a perspective view o't' my i 1 These lugs embrace the surface of the tooth "reversible clip.

In the acco'nrpanying drawings similar letters of reference refer to corresponding parts throughout the several views. Incoristructing my improvedharrow it. is

preferably constructed in two parts, with central hinges toaccommodate the uneven surface of theground and to facilitate the passage of stone and similar obstructions. It is quite obvious that any other form of constructionmay be adopted without departing from the spirit of my invention. For forming a broad wearingsurfacc on the under side of the frame and to facilitate the construction of my improved barrow, I provide angle draft bars a a a and a a a, which are preferably formed of steel with an angle-bend in cross-section, substantially as indicated in Fig. 2. One angle of the bar forms abroad wearing-surface'when beam. The angle-bar is provided with perfo rations on either side of the cross-beams at their intersection. The two are held in union by bolts b b, which are inserted in the perforations in the angle-bar and passed through the perforated ears in'the clip, which forms a device for holding the tooth in place. The bolts are provided with'threaded nuts.

I provide two or more cross-beams, which are placed substantially at right angles to the draft-bars, and are preferably of wood, with cross-grooves for receiving one angle of the draft-bars. It is quite obvious that the crossbeams maybe placed at an oblique angle from the draft-bars without departing from the spirit of my invention. I

vb' b b and b? bb represent the cross-beams, which are held in union with the draft-bars, substantially as hereinbefore described.

I provide curved teeth 0, which are bent forward, upward, rearward, and downward, so that the point of each tooth falls :below the 1 frame, and each tooth is adjustable up or down to regulate the cut. The teeth are attached to the frame, on which they'are adjustable by clip a, which is provided with. projecting perforated ears 0 cv and lugs.

upon either side,.eac'h tooth being admitted between the lugs, which are provided to prevent'the teeth from turning, and each clip may be used on either half of the harrow by reversing the same. The extremes of the clip embrace the inner circle of the tooth. the latter being placed on the upper surface of the frame.

The circular form of the tooth, with the straight clip placed thereon, forms a space between the tooth and the center of the clip, by means of which an elasticbearing is formed, by means of which a continuous strain is kept on the nuts, thereby preventing the samefroni jarring or working loose. By loosening or tightening the nuts and moving the tooth an adjustment of the tooth is secured.

The harrow shown in the drawings has a central joint or joints, which are formed by bending the ends of the angle draft-bars and perforating the same, which are placed in union and held by bolts or rods.

d d d represent the bent and perforated ends may be used without departing from the spirit of my invention.

What I claim'as new, and desire to secure by Letters Patent, is-

1. The combination, in ahar'row having cross-beams with cross grooves on the under draft-bars, of the draft bars constructed of metal, having an angle-bend in the. cross-sec- 5 tion, with. means for retaining the two in fixed relation, substantially as described.

2. The combination, in a barrow, of the grooved cross-beams and'the metallic draftbars having an angle-bend in cross section for fitting the grooves in the cross-beams, with means for retaining the two in fixed relation, substantially as described; 7 3. The combination, in a harrow having metallic angular draft bars and slotted cross- 5 beams for fitting the angle of the draft-bars at the intersection, of the curved spring-teeth, a fastening-clip,formed' asdeseribed, whereby its extremes engage the inner surface of the tooth, with means for holding the clip in fixed relation to the tooth, substantially as set forth.

4. The combination, in a barrow having metallic angle draft bars and slotted cross-bars for fitting the angle of the draft-bars at their intersection, of the curved tooth held to the 3 5 upper surface of the frame, substantially as described.

6. The combination, with the cross-beams,

draft-bars, and curved tooth on the upper surface of the cross-beams, of the reversible clip 0 with perforated ears and projecting lugs extending from both surf-new of the clips for engaging the tooth and preventing the same from turning and for adjusting the length of the cut of the tooth, with means for holding the clip to the tooth, substantially as described.

6. A harrow having the following elements in combination: cross beams, the metallic draft-bars formed with an angle-bend in crosssection, the curved tooth, the fastening-clip 0 for engaging the tooth, the retaining-bolts for engaging the clips, and angle draft-bars for retaining'in fixed relation the tooth, cross-beams,

- and angle-bar, substantially as shown.

7. The combination, in a harrow having metallic angle draft-bars and slotted cross-bars fitting the angle of the draft-bars at their intersection, of the hinges formed by the extension ends of the angle draft-bars perforated and bent for overlapping each other, with bolt or rivet for securing said hinges, substantially as described. side of the beam for receiving the angle of the.

8. A harrow having the following elements in combination: cross-beams, metallic draftbars formed with an angle-bend in cross-see tion, the curved teeth, fastening-clip for engaging the tooth, retaining-bolts for engaging the clips, and angle draft-bars for retaining in fixedrelation the teeth, cross-bars, and draftbars, bent, perforated, and lapping ends of the metallic draft-bars held in union by rod orbolt for forming a joint or hinge, substantially as set forth.

9. The combination, in a barrow, of the angle draft bars, the grooved cross-beams, and the teeth at the intersection, substantially as shown.

10. The combination, with a barrow-frame, of a curved spring-tooth, a flat seat on which the tooth is mounted, and a fasteni nz-clip spanning thetooth and held thereto bybolts and 80.

nuts.

4 11. The combination of a curved springtooth mounted on a flat seat on the frame, a fastening'clip spanning the tooth and enguing theinner curve thereof, and bolts and unis, for the purposes slated.

12. A clip, combined with bolts, for fastening a spring-curved barrow-tooth to a seat, substantially as described, the essential characteristics of such clip being that it bears upon the tooth and engages by projections its opposing edges to prevent edgewise vibration thereof.

In witness whereof I have afiixedmy signature in presence of two witnesses.
