UNITED STATES PATENT OF ICE.

J. FERDINAND LYMBURNER, OF CHICAGO, ILLINOIS.

HARROW.

SPECIFICATION forming part of Letters Patent No. 268,915, dated December 12, 1852.

Application filed April 27, 1882.

(ModeL) To all whom it may concern Be it known that I, J. FERDINAND LYMBURN- ER, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Harrows; and 1 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, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon,which form a partofthis specification. y

The object of my invention is to produce a drag or barrow of that class which consists of a number of teeth of such form and construction as to permit their connection one with another in any desired number; and it consists in certain features hereinafter described, and specifically set forth in the claims.

Figure l is a perspective of a drag constructed in accordance with my invention. Fig. 2 is a perspective of one of the sections of the drag; and Figs. 3,4, 5,6, and 7- are modified forms of cross-bars.

Like letters refer to like parts in all of the figures.

A represents the section of the drag, which is, in fact, two teeth and'a connecting portion formed of one piece of suitable material, iron or steel being preferable. It is evident that substantially the same section maybe formed of cast or malleable iron. This section consists specificallyof two teeth, a and to, having a connecting portion orstrip, a and intermediate loops, a, all formed in the shape shown, and of one piece of material, as described. It will be seen that two or more of these sections placed side by side present to the front equidistant loops which in each section is the center of the connecting portion 0?, and these loops are the same distance apart as the loops at, so that said rear loops of a single section may be hooked into the connecting portion of two other sections at its rear. In the same manner successive rows may be connected one with another. As the means of retainingthe sections together, I may use bars B having apertures b distanced from each other to receive the loops a and the sections. These bars may be either of wire, with an eye formed at each end by bending the wire, or a wire having more than two eyes so formed,or a plate having holes punched therein, or a bar of suitable material having staples projecting therefrom, or simplyasplit ring of wire,as shown clearly in Figs. 3, 4, 5, 6, and 7.

In connecting the sections to form the drag the bars are first slipped upon the loops a and then other sections passed through said loops and bars slipped upon them, and other sections passed through these, and so on, increasing the number of sections in each of the rows by one. Now, it will be noticed that where two or more sections are placed side by side, two teeth occur at points in the line of teeth. These being unnecessary, one of them is cut or removed from the section, as clearly shown in the drawings.

A drag constructed in accordance with the above description has flexibility longitudinally and transversely. The section is simple in construction, can be rapidly manufactured at comparatively slight cost, broken teeth may be readily replaced, and the size of the drag may be increased or reduced, as desired, with facility.

Having described my invention, what I claim as new, and desii e to secure by Letters Patent,

1. The section A, consisting of teeth a a, the open loops a a and the connecting portion a substantially as shown and described.
