PATENT JAMES H. BARLEY, OF SEDALIA, MISSOTIBI.

HARROW.

SPECIFICATION formingpart of Letters Patent No. 236,292, dated January 4, 1881.

Application filed October 528, 1880.

To all whom it may concern Be it known that I, JAS. H. BARLEY, of Sedalia, in the county of Pettis and State of Missouri, 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 pertains to make and use it, reference being had to the accom 'ianying drawings, which form part of this specification.

My invention relates to an improvement in harrows; and it consists, first, in the castings by means of which the teeth are secured to the sides of the harrow-beams, and which castings have stops formed on their inner sides to catch against the upper or lower edges of the beam, and thus limit the movementot' the teeth as they turn upon their pivots; second,

in securing to the sides of the iron beams fiat-headed bolts, the heads of which are made wide and flat, so as to brace the beams, while the upper ends of the bolts pass through the cross-bars which unite the beams together; third, in making a notch or're-cess in the lower. end of each tooth. for the purpose of giving each tooth a double cutting edge or point.

Figure 1 is a vertical cross-section taken through the'center of the barrow. Fig. 2 is a. side elevation of the harrow, and Figs. 3 and 4 are difi'erent views of the fastening device for the teeth. Fig. 5 is a plan view of the barrow complete. Fig. 6 is an end view of the harrow.

A represents the beams of the harrow, which are here made of angle or L-shaped iron bars, of any desired degree of width or thickness. These beams are made from an gle-iron for the purpose of making the harrow as strong and solid as possible, and yet not make them as heavyassolidiron barsorbeams. Thesebeams may be secured together at the ends by means of an gle-shaped cross-pieces, or the cross-pieces may consist of small flat bars, which are se cured to the top of the beams, as may be pre-: ferred. In order to strengthen and brace each one of the angle-beams A where they are secured to the cross bars or braces, the screw-bolt G is provided with a wide flat head, d,which is riveted to the vertical part of the beam A, as shown, and which flat head serves'as a brace (ModeL) for the whole of this vertical part. Through the horizontal part of the an gle-beam are made suitable holes, up through which the screw ends of the bolts pass,'a-nd these screw ends also pass through the cross-pieces which connect the beams together, and receive the nuts upon their upper ends.

The fastening device, by means of which each barrow-tooth is secured to the side of the angle-beams A, consists of a casting, D, of any desired shape or size. and which has a hole through its center for the clamping-bolt F to pass through, and this bolt serves not only to hold the teeth in position against the casting, but as a pivot upon which both the casting and the tooth moves. Upon the front side of this casting D is made a suitablyshaped recess, to receive the harrow-tooth H, which tooth is made from flat bars of steel, as here shown, having a sharp cutting-edge upon its front and a blunt edge upon its rear, so as to adapt it for different kinds of work. The outerend of the clamping-bolt is provided with an eye, thronghwhich the tooth passes, and the casting D is provided, at any suitable point, with a projection, I, to catch in any one of a series of notches which is made in one of the edges of the tooth, for the purpose of bold ing the tooth in any desired position into which it may be adjusted. By having a number of these notches made in the edge of the tooth the tooth m ay be made longer or shorter, as may be desired, and after it has once been adjusted into the position it will be impossible for the tooth to move up and down until the clamping-bolt has been loosened sufficiently to release the notch from this projection on the casting.

Upon the inner side of the casting, where it projects above and below the edges of the angle-bar, are formed the stops 0, which have their inner edges shaped as shown, so that the casting may be turned either forward or backward, and thus hold the tooth at an angle, when the harrow is drawn in either direction. It so desired, these stops may be so placed that when the casting is turned in one position it will not move quite so far, and thus hold the tooth vertically to the side of the beam, while if turned in the other direction it will turn farther around upon the pivotal bolt,

and thus hold the tooth at any oblique angle desired.

Each tooth being provided with a sharp and a blunt edge, so as to work from either side, it has its lower end notched or recessed, as shown, so as to make two sharp and independent cutting-points, P. WVhere the end of the tooth is left solid, or but a single point is formed upon the tooth, it will not cut sod, hard ground, corn-stalks, and other such substances, as it may pass over, and is not so well adapted for work in any way; but where two separate and distinct cutting-points are made, as here shown, the tooth will penetrate the ground much more freely, especially when the teeth are drawn along at an angle, as here shown, so as to give a drawing out.

I am aware that barrow-beams have been made out of U-shaped iron heretofore, and this I disclaim. Angle-iron, such as is here shown, is not onlylighter, cheaper, and equally strong and efficient, but the tooth can be applied much more readily and cheaply.

Having thus described my invention, I claiin 1. In a harrow, the combination of a beam, the casting D, secured to the side of the beam by means of the clamping-bolt F, which has an eye on its outer end'for the harrow-tooth to pass through, the casting being provided with stops on its inner side to catch over the edges of the beam, and which stops have inclined edges, so as to allow the tooth to be inclined in either direction, substantially as shown.

2. The combination, in a harrow, of a flat iron beam, with the bolts 0, having the large flat heads (I, and the cross'bars which unite the beams together, the bolts being riveted to the side of the beams, and then made to pass up through the cross-bars, substantially as described.

3. A barrow-tooth having a sharp cuttingedge in front and a blunt edge at its back, and having its lower end recessed, so as to form two separate and distinct cutting-points, substantially as specified.

In testimony that I claim the foregoing l have hereunto set my hand this 26th day of October, 1880.

J. H BARLEY.
