HARROW.
SPECIFICATION forming part of Letters Patent No. 236,756, dated January 18, 1881,
Application filed October 28, 1880. (ModeL) 5 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 accompanying drawing, which forms part of this specification.
My invention relates to an improvement in barrows; and it consists in loosely attaching three sections of the harrow together, so that they can move back and forth upon each other, and fastening these sections to two equalizingbars by chains, which are fastened to the ends of the bars and the corners of the sections, and attaching the bars to the ends of the double-tree by means of chains, which have their rear ends secured to the bars out beyond their centers, as will be more fully described hereinafter.
The object of this part of my invention is to so connect the three sections of the harrow together that they will have a reciprocating motion back and forth upon each other as they are drawn along, instead of a dead-center draft, as has heretofore been the case.
The figure shows a plan view of my invention.
A represents three sections of a harrow, which are loosely connected together by means of the horizontal coupling-rods B and hooks O in such a manner that the sections can move back and forth upon each other, and have a free and independent movement of their own as they are drawn along. These three sections are attached to the two draft-bars D by means of the four chains E, the two outer ones of which chains are fastened to the outer ends of the equalizing-bars and to the corners of the sections A, as shown. The inner two of these chains are fastened to the inner ends of the two equalizing-bars, and to one corner of the middle section of the harrow. The two equalizing-bars are secured to the double-tree F by means of the chains G' and the two eyes I, and which chains G and eyes I are fastened to the ends of the double-tree and to the front edges of the equalizing-bars at a point out be- I yond their centers. The fastenings by which the three sections of the harrow are attached together will not permit the sections to close upon each other as they are drawn along, and as the inner ends of the equalizing-bars are both attached to the same corner of the middle section, and the two outer sections to the outer ends of the two equalizing bars, the center section acts as a regulator upon the other two sections, and vice versa. If. as the harrow is being drawn along, one of the outer sections should encounter any obstruction, the center section of the harrow would be forced forward in advance of the section which was being held back until the section was released, when the three would equalize each other again, and when the central section is in any way obstructed the two outer sections are forced forward. In this manner the three sections of the harrow play back and forth upon each other, instead of there being a dead-center draft in the center section, as is always the case when the three sections are attached to a single draft-bar.
The point at which I have found it most expedient to fasten the chain G and the eyes I to the equalizing-bars is two-thirds of their length from their inner ends. By thus dividing the bars so that one-third of their length is used to balance the outside sections of the harrow, and the other two-thirds the central section, the two outside sections are made to balance the central section under any and all circumstances and allow the central section a vibrating or endwise movement, something which has never heretofore been accomplished. By thus having the parts to reciprocate back and forth upon each other, the harrow will free itself much more readily from obstructions, the draft is not so hard upon the team, and the work performed is better and more even in every way.
Having thus described my invention, I claim 1. The combination of the three sections of a harrow, connected together so as to play back and forth upon each other, with the chains which unite the sections to the ends of the equalizing-bars, the chains G, and eyes I, and double-tree, the two ends of the equalizingbars being connected to the central section of the harrow, substantially as shown.
2. In a harrow composed of three sections,
the equalizin g-bars, as described, so as to cause the two outer sections to equally balance the central one, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 26th day of 15 October, 1880.
J. H. BARLEY.
