ROW-MARKER FOB PLOWS.

- Specification of Letters Patent.

Patented Jan. is, 191e.

Application led September 16, 1909. Serial No. 518,107.

To all whom it 'may concern.'

Be it known that I, GEORGE WILLIAM BROWN, a citizen of the UnitedStates, re-v siding at Brewton, county of Eseambia, and State of Alabama, have invented certain new and useful Improvements in Row-Markers for Ilows, of which the following is a specification.

This invention relates to row markers for plows.

-The present invention has for its object the provision of a row marker of simple, inexpensive, strong, light, and durable construction which can be readily attached to any' plow beam and will embody novel features whereby it may be adjusted to mark wide or narrow rowsto any desired extent, will be suitably braced and held in marking position, and will be capable of reversa from one side of the plow to the other.

The foregoing object is carried out by the provision of a novel row marker whose con struct-ion is set forth fully hereinafter and recited in the appended claims. n

In the accompanying drawings :T Figure 1I is a perspective view of the invention as applied to an ordinary plow; Fig. 2, an enlarged section taken longitudinally of the marker bar and crosswise of the plow beam; Fig. 3, an enlarged section taken longitudinally of the supporting plate; and Fig. 4, a detail view showing the manner of connection of the bar to the marker and ofv the cords or wires to said marker.

The beam of an ordinary plow is shown at 1. Disposed. on top of the beam l is a supporting plate 2 which is connected to the beam by yokes 8 which are preferably pivoted at 4 to the'ends of the supporting plate. The support-ing plate is adjustable to diierent positions onthe plow beam by the provision of the nuts 5 carried by the yokes 3, as the supporting plate maybe slid along to any position on loosening the nuts and clamped where desired. Extending laterally on opposite sides of the plow beam and formed integral with the supporting plate are theextensions 6 and 7 which are either of' trough shapev or provided with lugs 58;

vantages of a marker bar of fixed length,

which can not bo satisfactorily used among stumps and stones, I provide a marker bar composed of two relatively adjustable parts are` adapted to be brought into register, to extend or shorten said bar, detachable bolts ,l and nuts 14 providin the means for clamping the parts of the liar together in its adjusted condition.

The marker 15 is double, being composed of duplicateparts extending above and below themarker b ar. This marker is preferably formed from a single piece of steel whose end parts are bowed to 've it sutlicient resiliency .so that it will yield and not break if it catches on an obstruction, the intermediate art of the marker being provided with a oop 16 which receives the end of the marker bar section 12 and 'is secured thereto by a bolt or other fastening 17.

Cords `or wires 18 and 19 running respectively from the marker to the crosspiece of the plow handles-and to the clevis pin, constitute means for bracing the marker bar and marker'but theytrough'shape construction of the extensions 6 and 7 relieves 10 and 12, each having openings 13 which the pivot 11 from strain by reason of enfrom the plow, such adjustment' being quickly accomplished and the wires or cords 18 and 19 being let out or taken up, according to requirements. When it is desired to reverse the marker, the cords or wires 18 or 1 9 are loosened and the marker bar and f marker swung on the bolt 11 to the opposite the respect-ive marker oints will be reversed. By providing a dou le marker, it is unnecessary tol adjust the marker in any manner as it is simply swung over from one side of the plow to the other and the cords or wires 18 and 19 tend to tighten it in its new position to secure it.

I claim as new and desire to secure by Letters Patent, is 1. In a marker for plows, the combination with a supporting plate adapted to rest on Athe, plow beam, of releasable yokes ada ted to hold said plate on the plow beam w ich have cross-pieces hin ed to the said Sup- Porting plate, a. mar er bar connected 't0' 1,1'0

said supporting plate, and a marker carried by the bar.

Having thus described my invention what side of the plow, whereupon the position f f 2. In a marker for p1ows,jthe combination` with a supporting plate having ears extending orosswise thereof and provided with extensions adapted to extend ontwardlyon opposite sides of .the plow beam and which have parallel retaining'lugs or flanges, of yokes hinged to the supporting plate beyond the ears aforesaid and ada ted to embrace the plow'beam, a marker er consist ing of e section which is hinged on a pivot which connects the ears and another section which has an adjustable connection with the sent/ion aforesaid7 wherebysaid sections may be relatively extended laterally, and e double markersecured to the section last-named.

said parts being disposed and related so that 15` the marker bar may be swung from side to side and made to lie between either of the sets of retaining lugs or anges. In testimony whereof, I hereunto aiiX my signature" in presence of two witnesses.

GEORGE WILLIAM BROWN. Witnesses:
