HARROW.

Specification of Letters Patent.

Patented J an. 2, 1912.

Application led July 23, 1910. Serial No. 573,450.

To all whom it may concern:

Be it known that I, WILLIAM THoRN, a citizen of the United States, residing at Arnaudville, in the parish of St. Martin, State of Louisiana, have invented certain new and useful Improvements in Harrows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

This invention relates to harrows.

The object of the invention resides in the construction of a harrow particularly adapted for use in cultivating cotton, which is provided with means for removing the diseased forms or squares, caused by the boll weevil, from the cotton plant.

To this end the invention consists in the details of construction and the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views; and -in which,

Figure 1 is a side elevation of a harrow constructed in accordance with the invention; Fig. 2, is a front view of'same; Fig. 3, a plan view of the harrow; and, Fig. 4, a section on the line 4-4 of Fig. 3.

Referring to the drawings, the harrow is shown as comprising a pair of eonvergently disposedtoothed beams 10 and 11 connected together at opposite ends respectively by arched members 12 and 13. The arched member 12 has its terminals bent outwardly and disposed upon the upper sides of the beams 11 and 10 respectively. A single bolt extends through each of said beams and each of said outwardly bent terminals so that a pivotal connection between each end of the arched member 12 and the beams 11 and 10l is had. The arched member 13 has its terminals bent outwardly as at 14 and 15 and disposed upon the upper sides of the beams 11 and 10 respectively. The outwardly bent portion 14 is provided with a plurality of spaced apertures 16, while the outwardly bent portion 15 is likewise provided with a plurality of spaced apertures 17. These apertures 16 and 17 enable the beams 10 and 11 to be moved toward and away from each other at the end adjacent the arched memi ber 13; said beams being secured in a desired adjusted position by bolts 18 passing through said beams and through the apertures `14 and 15. The arched members 12 and 13 are strengthened by means of mey tallic straps 19 and 20, which straps also serve to assist in supporting handles 21 andV Another chain 26 is hung from the arched member 13 by means of straps 27 and 28. The strap 27 encircles both the arched member 13 and the handle 22 while the strap 29 encircles both the arched member 13 and the handle 21 such engagement between the straps 21 and 22 and handle holding the former against longitudinal movement on the arched member 13. 'Ihe straps 23, 25, 27 and 28 are detachably mounted upon their respective supporting parts so that various lengths of chain may be disposed between straps engaging a given arched member.

In the cultivation of cotton t-he beams 10 and 11 are disposed on opposite sides of a row of cotton plants and during the movement of the harrow the chains 23 and 26 will engage the foliage of the plants and remove therefrom those portions which have been attacked by the boll weevil. It will be apparent that the chains 23 and 26 may be.

easily adjusted so as to properly operate upon vplants of diierent heights.

While the harrow has been described as particularly adapted for use in the cultivation of cotton it will be obvious that same may be utilized with equal facility in cultivating plants of any type which are disposed inrows.

Having thus described the invention what is claimed as new is:

A harrow comprising a pair of spaced toothed beams, arched members connecting said beams at spaced points, bars connecting said arched members at spaced points and disposed respectively on opposite sides of the longitudinal axis of the harrow, handles secured to one of said arched members and to said bars respectively, a pair of straps encircling one of said arched members, each ioo having portions thereof disposed Qn oppo-v each arched member respectively and dis- 10 site sides of respective connections between posed between the beams.

said bars andv arched member whereby said In testimony whereof, I aiiiX my signa straps are held against longitudinal moveture/in presence of two witnesses.
