CORN-HARROW.

SPECIFICATION forming part of Letters Patent No. 270,241, dated January 9, 1883. Application filed August 28,1882. (No model.)

To all whom it may concern Be it known that I, SAMUEL Y. MILLER, residing in Union county, Indiana, 'near Gontreras, Butler county, Ohio, haveiuventcd certain new and useful Improvements in Corn- Harrows, of which the following is a specification, and the accompanying drawing a perspective View.

This invention relates to barrows for operating at once upon both sides ot a corn-row, as hereinafter specified.

The device is to be used in connection with a wheeled frame or sulky, such as is commonly used in connection with sulky plows and cultivators.

In the, drawing, common sulky used for plows, 850. This axle may be straight, as shown, or it may be arched to pass overghigher corn.

B B are parallel beams freely attached to the axle A, so as to oscillate vertically and horizontally, and projecting rearward; G C, handles attached to the beams; D D, harrowframes below the rearends of the beams; E, barrow-teeth; 1*, a share-tooth atinner rear extremity ot'harrow-irame; Gr,iI0Il tooth-seats, located against the sides of the barrow-frame; H, 'eyebolts to receive the tooth-shank and clamp the tooth and tooth-seat against theharrow-t'rame; I, the shanks of the teeth; K, a snspension-bar from beam to prow of barrow-t'rame; L, the attaching point of suspension-bar K to beam, being a pivot-bolt with two or more holes provided for it, so as to admit of vertical adjustment of the suspended harrow-frame; M, a diagonal draft-rod from beam to a point near the bottomof the suspension-rod K; O, a break-pin atjuncture ot' draft-rod M and suspension-rod K; P, a hookand-eye connection between bottom of suspension-rod K and barrow-frame; Q, a rear suspension-rod, pivoted to beam at It, in a manner similar to L, and attached to the harrowframe at S, the same as the suspension-rod K is attached at P; T, a metal arch-bar, journaled at U to the barrow-frame; V, a clamp for binding the rear suspension-rod, Q, to the A represents the axle of a arch T when desired; W, the inner rear extremity of the barrow-frame, and W the outer rear extremity of the barrow-frame. \Vhile only one of the barrow-frames is shown as provided with teeth, it is to be understood that both frames are similarly provided.

In operation the double barrow D D dies the corn-row, W, running close to the growing corn. The share-teeth I thus running close to the corn, throw the soil away from the corn and leave the corn upon a slightly-elevated ridge. Only certain conditions of crops and soil render this necessary, and the share-teet h 1*, having shanks like the harrowteeth E, may be removed and barrow-teeth put in their place. In some cases it may be desirable to put barrow-teeth at W in place of shareteeth I and to put the shareteeth in the next forward position, which brings them farther from the corn and gives a harrow-tooth close to the. corn. The two harrowframes D D, being hung freely at points S and P, are at liberty, when clamp V is loosened, to he self-adjusting to suit the slope of the land each way from thecorn-row. The arches T permit the two barrow-frames to be adjusted to suit a certain slope, and to be firmly clamped in the proper position. The suspension-rods K and Q being adjustable in length, by altering the pivot positions at L and It permits stradeither the front or rear of the harrow-frames to be adjusted to work at a greater or less depth with reference to the radial position of the beams B. The form of tooth-hold'erGgives a substantial means for attaching and detaching the teeth.

Instead of the triangular form of harrowframe shown, any of the well-known shapes may be employed.

1 claim as my invention- The combination,substantially as set forth, of axle A, beams B, barrows D, suspensionrods K and Q, arches T, and clamps V.
