E. W. HEWITT, OF PECA'IONICA, ILLINOIS.

- Letters Patent No. 84,87 9, dated December 15, 1868.

IMPROVEMENT 11v sULxY-HARRow.

The Schedule referred to in these Letters Patent and making of the same.

To all whom this may concern:

Be it known that I, E. W. HEWITT, of Pecatonica, in the county of \Vinnebago, and State of Illinois, have invented an Improved Sultry-Harrow; and 1 do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and letters marked thereon, making a part of this description, in which Figure 1 is a perspective representation of my invention. f

This invention relates to an improvement in that class of harrows which are supported and guided by a frame attached to an axle and wheels; and

Its nature consists in the novel arrangement of chains, pulleys, and levers, whereby the harrow can be readily operated by a person riding on the sulky.

To enable othersto fully comprehend the construction and operation of my invention, I have marked its various parts with distinct letters, and will now give a detailed desciiption of the same.

A represents the axle,

B B, the wheels, and v G C, the frame, which are conveniently arranged to support my device. 1

An ordinary tln'ee-coinered barrow, W, is suspended from this frame 0 O, by the following means:

A suitable chain or rope, P, having a ring, N, attached, is fastened, at its forward end, to the clevispin 1;, and, at the other end, to the rear of the frame, at K, and it is used to keep the harrow in place under the frame 0 O, and especially when the wheels B B are run backward.

Chains, (I (Z, are fastened to the ring N and to the sides 0 G of the frame, and they are used to prevent the forward end of the harrow from having too great a lateral motion. v

The lower ends of chains R S, R S, are fastened to the burrow at J J, J J, or at such points as will hold it level when it is raised up, and their upper ends are fastened to rings, M M.

Standards, 1) D, are tenoncdinto the side-pieces O O of the frame, and they support a cross-piece, E, to

which are fastened sheave-blocks, G G; and chains, T

T, which fasten to-the rings M M, pass over pulleys, n n, in the blocks, and fasten to levers, ll ll, atv I I.

These levers, at their lower ends, are hinged to a rod, H, which is fastened to the side-pieces U G, and they are used to raise and lower the harrow W, and are held to the axle A, when the barrow is to be moved to or from a field, by means of hooks or catches, V V, putthrough said axle, or otherwise fastened to it.

A draught-chain, Y, has one of its ends fastened .to the forward end of the tongue, and the other end fastened to the clevis X, and it is used to draw the har row forward, instead of an evener, the latter being fastened to the tongue in the usual manner, for attaching horses to sulky-cultivators.

Operation.

I The driver is supposed to sit on the seat, shown at A, and in this position he can reach the levers F F,

and raise one or both sides of the harrow, asthe case may require.

This invention will be found very convenient for cultivating soil and covering seed, as the driver is enabled to ride'and operate the barrow much more easily than he can do the same work when walking,

and he can also gauge the harrow to run any required depth in the ground.

Having thus described my invention,

WVhat I claim, and desire to secure by Letters Patent of the United States, is-

' 1. The harrow W, suspended by ropes or chains, R, S, and T, and held in place by chains, (Z (Z and P, and drawn by a chain, Y, substantially as and for the purpose set forth.

2. The combination, with the harrow W, with chains S, R, and T, hooks V V, pulleys n n, and levers F F, the latter being used to raise and lower said harrow, substantially as described and shown.

E. W. HEWITT.
