HARROW.

SPECIFICATION forming part of Letters Patent No. 352,28}, dated November 9, 1886.

Application filed April 17, 1886.

To all. whom it may concern:

Be it known that I, ARTHUR Mo'r'r WORD, a citizen of the United States, residing at Rome, in the county of Floyd and State of Georgia, have invented certain newand 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 appertains to make and use the same.

My invention relates to barrows, and is part-icularl y well adapted to side barrows, and

for the ready and easy adjustment of the teeth and their standards to different positions nearer to or farther removed from the draft pole or beam or draft-line on the harrow, so as to regulate the width of the harrow, as will appear hereinafter.

In the drawings, Figure l is aplan view of the harrow; Fig. 2, a side elevation thereof; Fig. 3, a perspective thereof.

The letter A designates the pole or beam, having pivoted thereto by suitable means for instance, by bolts B at right angles to it one or more cross-bars, 0, preferably of metal, two cross-bars being shown, which lie under the beam.

To the crossbars G are secured the curved standards E, to which the points F are affixed.

cross-bar O, and eXten d from the rear to thefront cross-bar and lie under both bars. The two outer standards are jointed to the rear crossbarsby bolts B and to the front cross-bar by bolts B, while the middlestandard is pivoted the cross-bars to the beam. Bysuoh construction, when the cross-bars are turned on their pivotal connections, the end standards will be. adjusted on their pivotal connections, so as to assume aparallel position with the line of draft,

as shown by-dotted lines in Fig. 1, and will be brought nearer to the beam, so that the width of the harrow will be narrowed proportionately to the adjustment.

By placing the cross-bars beneath the beam and the standards beneath the crossbars the bars are more strongly connected and braced to the beam by the central standard than when otherwise arranged, and the draft on the curved Serial No. 199,225. (No model.)

portion of the standards is taken from off the pivots and thrown more directly up against the cross-bars, so that as a consequence the parts can be made lighter without detracting from their strength.

The adjustment of the crossbars and standards is effected by means of a curved bar, D, which liesunder the beam, and is secured to the front cross-bar O by ,means of the same bolts, B,that secu re the standards thereto. The advantage of such arrangement is that when the standards are to be adjusted the leverage is applied direct to the pivotal connection at both ends of the crossbar, so that there is less liability of the joint binding, and it will thus be made to adjust easier. Furthermore, it obviates the necessity of extra bolts, and also brings the leverage more directly on the stand ards at both ends of the cross-bar. The advantage of placing the curved bar under the beam is that any upward strain is thrown upon the beam instead ofupon the bolts, and a firmer connection can be made than when the rod is passed over the beam.

I prefer to bind the curved bar to the beam by a clamp-bolt, G, of any suitable constructionfor instance, as shown in the drawingswhich is held by nuts d, between which and the beam a plate, H, is preferably interposed. By such construction the curved bar can be made lighter, and the adjustment can be more quickly and easily effected and made to a greater nic'ety than when the bar is clamped by a bolt passed through holes in the bar, as shown in Fig. 1. The handles I are bolted to the beam, as shown.

My object is to provide a simple, light, and yet strong harrow in which the parts can be quickly and easily adjusted and the strain on 0 the parts will be distributed to the best advantage, and so I have constructed the parts as described. I wish to be understood, however, as making no claim to a plow with crossbars having standards bolted thereto and ad- 9 5 justable to bring thestandards nearer to or farther from, the beam to regulate the width of furrow, as I am aware that such, broadly, is notnew; but, 7
