HARROW.

SPECIFICATION forming part of Letters Patent No. 250,242, dated November 29, 1881. Application filed September 14, 1881. (No model.) Patented in New Zealand January 25, 1881.

To all whom it may concern:

Be it known that I, THoMAs HAXTON, of Gore, Otago, New Zealand, have invented certain useful Improvements in Harrows, of which the following is a specification.

Figure 1 is a plan view of my improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a perspective view of one of the harrow-sections. Fig. 4 is a perspective viewof another form of section.

Similar letters of reference indicate corresponding parts. I

The object of this invention is to facilitate the thorough cultivation of uneven ground and promote convenience in enlargingand contracting the harrow, as the work to be done may require.

Theinvention consists in a harrow constructed of sections of metal, each section made in one piece, bent horizontally in triangular form, with eyes at the ends of the arms, and also bent vertically below the eyes to form teeth, whereby, when the sections are linked together, a complete flexible harrow is made, as will be hereinafter fully described.

In constructing my improved harrow round or square rods or bars of metal of suitable size are cut into pieces A of proper length. One end of each piece A is bent to form an eye, B. At a distance from the other end of the rod A equal to the required length of a tooth, O, the said piece or rod is bent upward, forward, and downward, so as to form an eye, D, to receive an eye of an adjacent rod, A, and to cause the tooth O to project at right angles with the body of the rod A. The part of therodA between the eyesB D is then bentinto the form of an isosceles triangle, as shown in the drawings. The rods, bent in the manner herein shown and described, are then linked together by passing the eye B of one rod or section into the eye D of the adjacent rod or seetion A, to form a row of the desired length.

In forming a second row the eye D of each rod or section A is passed through the angle of a rod, A, of the preceding row before being passed through the eye B of the adjacent section. Some of the rods or sections A must have the eye D and tooth 0 upon the righthand end or arm of the said rod or section,

and some must have the said eye D and tooth 0 upon the left-hand end or arm. One rod or section of each row must have an eye, D, and tooth 0 upon both ends, so that when a row of sections is put together it may have a tooth,

. O, at each end of each section in the said row.

The front row of sections A, consisting of two or three sections, can be formed wholly of sections having an eye, D, and tooth O at each end, and each eye D is hooked into an angle of asection of the preceding row, so that there will be only half as many sections in the front row as in the next succeeding row. The angle of each section in the front row is provided with a hook, E, to be hooked into a clevis or staple attached to the draw-bar, which drawbar is not shown in the drawings. With this construction, by swinging a side section, A, into the position shown in dotted lines in Fig. 1, its eye B can he slipped off the eye D and tooth O of the adjacent side section, and can then be slipped oft the eye D and tooth O of the adjacent front section, and by reversing this operation sections can be easily added to the side of the harrow, so that the harrow can be readily widened and narrowed, as the work to be done may require. With this construction the harrow will be very flexible, so that it will adapt itself to any unevenness in the surface of the ground.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A harrow formed of the horizontally V- shaped sections A, bent at the ends to form two teeth, 0 O, and held together by eyes B D interlocking with each other and the vertices of the angles, as shown and described.

2. In a harrow, the sections A, formed, substantially as herein shown and described, of metal, each section made in one piece and bent horizontally in triangular form, with eyes at the ends of the arms, and also bent vertically below the eyes to form teeth, whereby, when the sections are linked together, a complete flexible harrow is made, as set forth.
