GEORGE H. JOHNSON, OF FINCAS'ILE, VIRGINIA.

HARRow.

SPECIFICATION forming part of Letters Patent No. 264,300, dated September 12, 1882.

Application tiled April 2l, 1882.

To all whom "it may concern:

Be it known that I, GEORGE H. JoHNsoN, ot'Fincastle, in the county of Botetourt and State Ot' Virginia, have invented certain new and useful Improvements in Barrows; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form apartof this specilication.

Figure 1 is a plan view of my im proved harrow. Figs. 2 and 3 are plan views, showing how the frame may be connected into different forms. Figa is a vertical sectional view on the line a: a', Fig. 1. Fig. 5 is a vertical sec tional view on the line y y, Fig. 1; and Fig. 6 is a perspective View of one of the teeth detached.

Corresponding parts in the several ligures are denoted by like letters of reference.

This invention relates to harrows; and it consists especially in an improved construction of the frame, byvvhich it is made capable of various adjustments, and by which it is specially adapted to be used in connection with the improved tooth shown and claimed in Letters Patent N O. 244,248, issued tom yself on the 12th day of July, 1881, all as will be hereinalter more fully described, and particu` larlypointed out in the claims.

Referring to the drawings hereto annexed, A represents the drat`t-bar of my improved barrow, which is made preferably ot' wroughtiron, and provided at each end with a hook, B, for the attachment of the draft.

The frame of the harrow consists essentially of four compound beams or bars, C, each consisting ot' an irou bar, D, and a wooden bar, E, placed loosely underneath the said iron bar, where it-is held in the manner which will be hereinafter described.

F represents one of the teeth of my improved barrow, which. consists ot' a triangular plate, pivoted between the sides of a forked tang or holder, G. The tangs or shanks pass through vertical openings H in the barrow-beams, on the upper sides of which they are secured by wedges I, or in any suitable manner. One side or edge of the tooth is thus caused to bear against the under wooden side of the harrowbeam, which acts as a washer to keep it in position and prevent it from turning. The parts D E of the barrow-beam, it will be observed,

(No model.)

neoted by straps or bars J, the inner ends of which are connected by a brace, K. In this xnanneradouble-Vshapcd harrowl is produced, the width of which maybe regulated by properly adjusting the braces J K. The barrow may be reversed by removing the braces and adjusting the beams and braces in the position shown in dotted lines and attaching the dralt to the other end of bar A. Vhen the teeth are provided with a sharp or sod edge either edge may be brought into play by simply reversing the barrow, as described.

In lieu of connecting the teeth direct to the bars O, said bars or beams may be connected by longitudinal beams L, to which the teeth are attached. In this manner I produce what l call a saw-tooth hal-row.

By connecting the outer ends of the beams C a. diamond-framed barrow is produced, as

'shown in Fig. 2.

By detaching the beams O from bar A and connecting them in pairs by the braces J, as

'in Fig. 3, a pair of 'V-shaped one-horse harrows or cnltivators are produced.

VMy improved harrow-frame is exceedimglpv simple, convenient, easily adjusted, and inex` gitudinal beams L, bent as shown, connecting the beams C and carrying the teeth, as set forth. In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
