ANCHOR FOR CORN-PLANTER CHECK-ROW LIN-ES.

SPECIFICATION forming part of Letters Patent -N'o.l 272,402, dated February 20, 1883.

Application tiled December 1, 1882. (No model.) v

To all 'whom fit may concern.-

Be it known that I, AALBEN BARNES, a citizen of the United States, residing at Bloomington, county otl McLean, State of Illinois, have invented certain new and useful Improvements in Anchors for Corn-Planter Check-Bow Lines; and I do hereby declare the following to be a full, clear, andexact description thereof, sufficient-t enable others skilled in the art to make and practice the same.

Myinvention relates to anchors for checkrowT lines, which serve by a lateral shift to properly position the check-line during a double traverse of the eld by the cdrn-planter.

The invention relates moreparticularly to adjustable anchors whereof that portion over which the check-line pulley runs is formed of v tlexible material.

rIhe present invention consists, specifically, in 'the combination, with a dexible anchor, ot' a stop made preferably adjustable, against which the line-pulley may bear to insure even planting of the field, as h'ereinalter set forth.

Referring to the accompanying drawings, Figure 1 is a plan view of the improved anchor with check-linein position for planting.

Fig 2 is a plan view to illustrate comparatively the operation of exible anchor with stop-block attached and unattached, the latter shown by dotted lines. Fig. 3 is a detail view of the stop-block.

A designates the main portion of the anchor, which is formed of any suitable flexible material, preferably cable-wire, chain, or rope.

At the ends of this main portion A rings or loops are formed, through which. pass the pins or stakes by means whereof the anchor is securely retained in the desired position in the tield. The check-row line B is connected to the anchor through the medium of the pulleyblock C, having the hook c.

The adjustable stop, as illustrated, consists of the bevel-faced block D, provided with a hole, d, and a groove, d', for the passage of vthe anchor rope or cable A, and to this block is secured t-he spring clip or strip D', which is also perforated to receive the rope or cable.

When the anchor has been set and the planter is in ,position to cross the field, as shown in Fig. l, (lull linesg) the stop-block D is adjusted 0n the anchorto a point that will bring pulley O in substantial alignment with stake-pin a and the trip mechanism of the The check-line B is thereby main- 5 5 tained essentially parallel to the prior course seeder.

| of the planter, so that as the planter advances the trip will be operated at regular intervals and the seed be deposited in even lines with the previouslyplanted rows, which latter is an advantage of first importance in subsequent cultivation of the field.

moved with some facility over the anchor to effect the desired adjustment, and yet when once set is held in place against any strain of the pulley C or check-line by the bite of springplate D' and perforation d. The bevel-face of block D keepspulley C snugly in position, as originally set; but when the retreating` planter approaches the opposite side of the field the companion pulley O, there situated, overrides the face of block D andv assumes position on the flexible anchor shown by dotted lines, Fig. l, so thatthe end rows can be evenly planted and the planting be nearer to the side Vot' the field than is practicable withV anchors which are not dexible.

By referring to Fig. 2 the benefit of the stopblock becomes apparent, for when there is none the pulley O tends to change its place along the anchor A', according to the strain of the check-line B andthe position of the planter, so that the rows 11 22 are'apt tobe in more or less irregular line.

It is obvious that other form of stop mechanism may be employed differing in construction from the stopblock heretofore described,

plate D and the check-row line B, provided structed to operate in conjunction with the seeding mechanism of a corn-planter, substantially as described.

In testimony whereof, Witness my hand this 28th day of November,.1882. v
