IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 221,664, dated November 18, 1879; application filed March 26, 1879.

To all whom it may concern Be it known that 1, TOLBERT V. CARDWELL, of Rose Hill, in the county of Amite and State of Mississippi, have invented certain new and useful Improvements in Harrows; and I do hereby declare'that the following is a full, clear, and exact description of the construction and operation of the same, reference bein g had to the an neXed drawings, ma-kinga part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of my A-formed harrow. in perspective. Fig. 2 is a plan view of same changed to a V-formed harrow. Fig. 3 is a plan view of the same changed in drawn lines to a two-barred righthand harrow. The dotted lines represent the same changed to a two-barred left-hand harrow. Fig. 4 is a plan view of the manner-of constructingthe bars forjoinin g them together. Fig. 5 is an elevation of T-headed bolts used in looking the harrow.

Identical parts in the drawings are designated and referred to by the same letters.

This invention relates to barrows; and it consists int-he improvements in the construction of the same, hereinafter fully described, and particularly pointed out in the claims.

A A represent the bars of the harrow, which carry the teeth. B represents the draw-beam. 0 represents the cross-bar of the harrow in the various positions in the combinations formed. D D are the handles, and d the supports, which are readily attached to the drawbeam B. E is an angled bar, which attaches to the free end of the draw-beam and to the bars A A, for the purpose of forming the right .or left handed side harrows and square harrow, which is provided with two series of holes, a e, for these several purposes.

The T-heade'd bolt F is provided with two hooks,f, which bolt-head and hooks enter from the under side of the bars AA, and set in the recesses f f and the hole f of the draw-beam when the device is used as an A-harrow, and hole f of the draw-beam when used as a V- harrow.

G is the kin g-bolt which attaches the drawbeam B to the cross-bar O, and provides a pivot for reversing the direction of draft.

Fig. 1 represents the bolt F, uniting the draw-beam and the converging ends I) b of the bars A A, thus forming an A-harrow provided with handles 1).

Fig. 2 represents aV-harrow,which is formed by removing bolt F, reversing the draw-beam B, and inserting bolt F in recesses ff and holef Fig. 3 represents a right and lefthanded side harrow, formed by means of the bar E, which is so angled as to hold the bars A A in position, as shown, by being attached at the draw-beam and the outer ends of A A. These bars, being pivoted to the cross-bar at c 0, they may be set at any desired angle by changing or lengthening the arm 0 of the bar E. A square harrow may thus readily be madeof the parts involved in the side harrows.

Cultivator-teeth may be used instead of common harrow-teeth, thus changing the purposes of the implement from a harrow to a cultivator.

When the device is used as aright or left hand or square harrow, the T-bolt hooks ff enter holes in either end of the cross-bar O, which is turned into the recess under the draw-beam, as shown at b b.

What I claim as new is- 1. In a harrow, the combination of the bars AA, constructed as described, in combination with the cross-bar O, the recessed drawbar B, the T-headed hook-bolt F, and the angle-bar E, constructed and operating together, as and for the purposes substantially as set forth.

2. In a harrow, the combination of the crossbar 0, pivoted at G to the draw-beam B, with the side bars, A A, pivoted to the outer ends of the cross-bar (J, and adapted to be reversed and secured to the draw-beam to form either a V-shaped or an A-shaped harrow, as set forth.

3. In a harrow. the bars A A, provided with recesses f f 2 in their under faces, near one end, said recesses f f being adapted to receive aportinn 0f the slnink F and the hooks In testimony that I claim the above I have ff of a T-slniped hook, in combination with hereunto subscribed my name in the presence the draw beam B, pert'nrmed to receive the of two witnesses.

remainder of the shank l, which is securely 1 held in place by the nut f, and the bar U, TOLBERT (JARDWELL' pivoted to the upper fan-(s 0f the bars A A, Witnesses:

and to the under face of the draw beam 1 JAMES J. SHEEIIY,

substantially as and for the pnrpuses set forth. \V. N. SEVERANOE.
