Definitions
- my invention consists in the construction of an implement which shall operate over obstructions and uneven surfaces more effectively than any harrow now in use.
- the harrowis composed of four parts, united by means of hook-and-eye joints, the hooks being placed on the leading part, and the eyes on the part following.
- clevises may be used for joints.
- the materials to be used are wooden scantling for the frame, (I prefer oak, two and a half by three inches,) into which steel teeth are inserted at suitable intervals, and forged or cast iron joints.
- the leader is constructed in the form of the ordinary A-drag, widened, and a central stick, 0, inserted.
- the central follower is of the simplest form of the A-drag, and is attached to the central stick 0 of the leader.

IMPROVEMENT IN HARROWS.
Specification forming part of Letters Patent No. 84.342, dated November 24, 1868.
To all whom "it may concern:
Be it known that I, JOHN CHASE, of the town of Farmington, county of Warren, and State of Pennsylvania, have invented an Improved Form of Harrow; and I do hereby declare that the following is a full, clear, and

The materials to be used are wooden scantling for the frame, (I prefer oak, two and a half by three inches,) into which steel teeth are inserted at suitable intervals, and forged or cast iron joints.
B, the leader, is constructed in the form of the ordinary A-drag, widened, and a central stick, 0, inserted.
1), the central follower, is of the simplest form of the A-drag, and is attached to the central stick 0 of the leader.
E E, the right and the left flanks, are in form like the common F square drag, of such proportions that one side in each shall be equal in dimension to the distances between the rear ends of the leader on m and those of the central follower n n. Other forms of drags may be used for the follower or flanks. In the construction of the several parts the
