HARROW.

SPECIFICATION forming part of Letters Patent No. 439,691, dated November 4, 1890.

Application filed March 26, 1887. Serial No. 232,598. (No modal.)

T aZZ whom it may concern:

' others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to-letters of reference marked thereon, which form a part of this specification.

My invention has reference to certain improvements in harrows, and pertains more especiallyto that class of harrows in which the tooth-beams are carried in j ournaled bearings, and thus adapted to be oscillated in the line of movement for the purpose of changing the position of the harrow-teeth to vary the depth or discharge rubbish.

My improved harrow belongs to that class in which the barrow-beams are placed at right angles to the line of movement of the harrow, the teeth in the several beams being so arranged in relation to each other that no tooth shall follow directly in the track of any other one.

My invention consists in the construction of the several parts and in their combination together, all as will now be more fully set out and explained.

In the drawings, Figure 1 is a plan of a harrow embodying my invention. Fig. 2 is an end elevation of the same, representing the position of the teeth when the implement is prepared for transportation, the normal position being shown in dotted lines. Fig. 3. is a detail of the end of the barrow-beam provided with the cap G.

The cap G is provided with inwardly-projecting side lugs H, through which said cap is fastened to the beam D, and the open sides of the cap Gare also furnished with flanges I, so that when the end of the beam D is inserted in the cap G the latter entirely incloses the end of the beam and protects the latter from moisture or-other injury. I

A A are the sections of the harrow, and the latter may be composed of any number of sections.

B is a draw-bar to which the sections are attached in any suitable mode at the front end of the end bars 0 of the respective sections.

D D are the harrow-beams, placed parallel with the draw-bar B and provided with the usual harrow-teeth E. In the end bars 0 the beams D D are journaled or pivoted, as hereinafter described.

G G are the metallic caps, preferably of malleable iron, placed upon the ends of the beams D, as a means of attaching the latter to the bars C. On the outer end of the caps G and integral therewith is formed the lug K, within which is provided a vertical slot K in line with the outer end of the main portion of the cap G. Transverse bolt-holes K are formed in the outer end of the lug K. The lug K is substantially parallel with and in front of a line drawn diagonally across theend of the cap and projects beyond the edge of and past the corner of the cap. By this construction when the barrow-teeth are vertical the position of the lug K is diagonally downward and forward from near the center of the cap G to a short distance in advance of the lower front corner of said cap, so that when the harrow-beain is in that position in which the teeth are vertical the bolt-holes K are in front of the cap G and slightly above- .verse bolts L, passed through the bolt-holes K and corresponding holes in the bars C. It is obvious that when the barrow-beams D are in their normal positionthat is, with the teeth E vertical-the lower edge of the .bars 0 will be about in the same plane with the lower edge of the cap G, and therefore carried suiiiciently above the ground as not to interfere with the passage under them of any loose rubbish lying on the surface of the ground, and when the beams D are thrown forward, so as to project the teeth E backward IOG horizontally, the bars 0 will rest upon the ground and support the beams D clear of the ground, in which position the harrow can be safely and conveniently dragged from one place to another; and if it is desirable to use the implement merely to crush the clods without any action from the teeth the beams can be rotated but part of the distance described, in which position the lower angle of the beams D will be nearly 011 the plane of the lower edge of the bars C.

M M are short metallic posts seated, respectively, at about the longitudinal center of and upon the beams D and provided at their upper ends with vertical slots M in the line of movement.

N N are central longitudinal bars placed edgewise in the slots M of the posts M and pivotally fastened therein by means of transverse bolts N.

O is a hand-lever, pivoted at its lower end to the side of the rear post M, directly above the beam D, and provided with the usual handpawl P.

R is the usual quadrant, seated on the bar N and provided with ratchet fitted to receive the p wl P. By means of the hand-lever 0, posts \and bars N all the beams D in each section n be oscillated coincidentally to any desired position, and there held in the usual way by the aforesaid pawl and ratchet. Thus the harrow is adapted to be used with its teeth in any desired position.

The position of the lugs K in reference to the beams D result not only in the advantage aforesaid of furnishing means of transporting the harrow with the teeth suspended above the ground, but also the further advantage of applying the draft on each beam when the harrow is in operation at the lower front corner of said beam, and as the resistance of the progress of the harrow is all below the beam D this point of draft is most advantageous as a means of relieving the strain upon the quadrant R.

"What I claim as my invention, and desire to secure by Letters Patent of the United States, is

In a harrow, the combination, with the perforated side bars 0, of the beams D,provided with teeth and arranged between the side bars, the end caps G, fitting upon the ends of the beams, each cap being provided with a lug upon its outer end, said lug being substantially parallel with and in front of a line drawn diagonally across the end of the cap and projecting beyond the edge of and past the corner of the cap, said lug being slotted to fit over the side bar-and perforated to correspond with the perforation in the side bar, bolts for securing the lugs to the bars, and means for rotating the beams, so that the lower edge of the side bars will be substantially on the same plane as the lower edges of the beams when the teeth are Vertical and below them when the teeth are horizontal, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
