IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 150,662, dated May 5, 1874 application tiled March 7, 1874.

To all whom it may concern:

Be it known that I,- FERDINAND Pos'r, of

- Moulton, in the county of Appanoose and State of Iowa, have invented a new and Improved Harrow, called the Universal Rever' sible Harrow, of which thefollowing is a specification:

Figure 1 of the drawings is a representa tion of a plan view of my harrow. Fi g. 2 is a side view of the same.

The nature of my invention consists in a diagonal brace, which is applied between two articulating harrow-sections, and which will prevent the sections from receiving independent endwise movements without interfering with their flexibility, in combination with the bars which couple together the harrowsections in front and in rear, as draft-bars, to one or the other of which the clevis or shackle is adjustably applied, as will behereinafter explained.

The following is a description of my invention:

In the annexed drawings, A A designate apart, by means of couplingbars G U, which are attached, by means of eyebolts c, to the cross-bars cc, which bolts allow free articulation of the sections, so that they will accommodate themselves to inequalities of the surface passed over. These bars G U have attached to them the shackle or clevis loop f, to which the. horses are hitched, which loop is removable and adjustable to one or the.

other of a number of perforations, 'i, through the bars. I am thus enabled to draw the harrow from any point along theline of either coupling-bars, according as it may be desired to harrow finer or coarser. To keep the two sections A A at a given distance apart, and prevent one section moving in advance of the other, I employ a diagonal coupling-brace, D,

The diagonal brace D, jointed to the sections A A, in combination with the front and rear couplingbars O G, as herein described.
