HARROW.

SPECIFICATION forming part of Letters Patent No. 370,154, dated September 20, 1887.

Application filed August 6, 1887.

To all whom it may concern:

Be it known that I, MARK O. MOORE, of Bunker Hill, Butler county, Ohio, have invented certain new and useful Improvements in Harrows, of which the following is a specifieation.

This invention pertains to folding harrows, and relates to the arrangement of folding sec tions and runners, whereby two runners are brought into operative position by manipulating a single folding section.

My improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a perspective view of a two-section harrow, illustrating my invention, the harrow appearing as in open position ready for its work as a barrow; and Fig. 2, a vertical section of the same in a plane at right angles to the axis of the hinge by which the sections are coupled, this view illustrating the portation upon its runners.

In the drawings, A indicates the non-folding section of the harrow, the same being formed by toothed timbers and cross'ties, as usual; B, the folding section, similar in general construction to the section A; O, hinges uniting the sections, so as to permit the folding section B to be folded over on top of the section A when the harrow is to be transported from the field; D, a runner formed of properlycurved bar-iron hinged to the inner timber of when the harrow is folded, as in Fig. 2, lying flat on top of the harrow and projecting toward the non-folding section; E, a similar runner hinged to the outer timber of the folding section; F, stops on the pivot parts of the runners, these stops serving to prevent the runners when turned upon their hinges from being turned more than at right angles to the plane of the folding section, and G a latch- Seriul No. 246,253.

ment serving to hold together the two outer edges of the sections when the barrow is folded.

It will be noticed in Fig. 1 that each runner rests upon the top of the next timber toward the non-folding section. If the outer edge of the folding section be lifted the folding section may be turned down flat upon the top of the non-folding section, and while this is being done the runners will automatically swing downward and project below the points of the teeth of the non-folding section, as clearly indicated in Fig. 2, in which it will be seen that the folding section presents its teeth upward, while the lower section has its barrow-teeth elevated considerably above the ground, the two sections being held in this position by the latchment G. In this condition the implement may be readily transported upon its runners. WVhen desired for use, the latch ment may be loosened and the upper sec tion thrown over into the position indicated in Fig. 1, the two runners automatically withdrawing from below the non-folding section and taking their position flatwise upon the top of the harrow.

I claim as my invention- In aharrow, the combination, with a nonfolding section and a folding section hinged together so that the folding section may be turned down flat upon the top of the nonfolding section, of a pair of runners hinged to the folding section and arranged to lie upon the top of the harrow when the same is open and to swing downward below the teeth of the non-folding sectionjwhen the harrow is folded, and a latchment arranged to hold the two sec tions together when folded, substantially as and for the purpose set forth.
