HARROW.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed May 8, 1907. Serial No; 372,495.

To all whom it may concern:

Be. it known that I, NICHOLAS A. SEIPEL, a citizen of the United States, and a resident of Healdsburg, county of Sonoma, State of California, have made certain new and useful Improvements in Harrows, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to harrows used for cultivating ground that has been plowed, and one of its objects is to construct such a harrow as may be used for tearing out the weeds between rows of vines or plants the distance of which rows is not the same in every case. For this purpose the harrow is made adjustable.

Another object of the invention is to make such a harrow as will be suitable for working between rows where there is a deep furrow between the several rows, as in the cultivation of rhubarb or asparagus.

Another object of the invention is to make such a harrow as may be used as a rigid harrow, or which may be used as a flexible harrow at will.

Other objects of the invention will appear as the description of the invention proceeds.

In the drawing, in which like numerals of reference refer to like parts throughout, the single figure is a perspective view of the harrow looking from front to the rear diagonally.

The harrow is provided with a center rail 1 made of angle iron, which has its front end upturned as at 2 to provide means to which to hitch the team. The rail 1 is provided on each side with a plate having a pair of eyes 3 to which the rails 5 and 5 are secured, said rails being capable of a hinge like movement at the eyes 3. These rails 5 extend outwardly to the rear and carry the teeth of the harrow, said teeth being of any desired form. At the rear end of the rail 1 is a plate 4 having an eyehole in each end, and bolted to the top of the rail 1. This eyeplate has a bar 7 run through each eye and extending outwardly to the side rail 5 nearest the center rail 1. The bar 7 is secured to this rail 5 by means of the clamp 14, and this clamp 14 also holds a short bar 8 in place said bar being alined with the bar 7 and being secured at its outer end to the outer bar 5. Both sides of the harrow are built in the same manner there being two of the bars 5 011 each side of the center rail 1.

The handles 9 are secured to the center rail 1 by means of a clamp 10 at their'lower ends, and by means of a pair of bars 11 which extend up to a point near the top of the handles, said bars 11 being joined at their lower ends and being secured to the plate 4 by the same clamp that holds it in its position on the center rail 1. Now it will be observed that this construction is such as to leave the side rails 5 hinged to the'center rail 1 in such a way as to allow them to be moved nearer to or farther from the handles. When the ground is in such condition'as to require it the harrow may be left flexible as described above, but it is often necessary to use means to hold it rigid. This means is the rod 13 which is secured at its lower end to the outside rail 5 at a point considerable distance from the center rail 1. The upper end of this rod is turned down in order that it may be placed in one of the holes in the plate 12 secured to the handle on the outside of the same. There is a rod 13 for each side of the harrow and likewise a plate 12 for each handle. It will be observed further that the outer rails 5 and the inner rails 5 are both adjustable, since by simply loosening the clamp 14 it is possible to move the rails closer together or farther apart as may be desired.

If desirable the section on one side may be raised off the ground entirely and thus the work will be done by one side of the harrow alone permitting the harrow to pass through very narrow rows. When rows that have been hilled up very high are sought to be cultivated all that is necessary is to raise both sides of the harrow to the desired amount and then a V shaped cutting surface will be presented to the ground, thus making it possible to tear the weeds out of a ditch like furrow without leveling the ground down in a way that is unsuited to the plants being cultivated. If it is desired to work ground that is very rough and uneven it may be necessary to take the rods 13 out of the plates on the handles and allow the sides to move up and down at will.

Modifications of the invention within the scope of the appended claims are reserved.

Having thus described my invention in such full and clear terms as will enable those skilled in the art to which it appertains to construct and use the same, what I claim as new and desire to secure by Letters Patent of the United States is as follows:

1. In a harrow, a central rail to which a team may he hitched, a pair 01 toothed rails hinged at their ends to the ccnter rail and extending outwardly and rearwardly there from said hinges permitting said toothed rails to move either horizontally or vertically, means to adjust the outermost rail with respect to the others, handles secured to the center rail near its rear end, a plate having a series of holes carried by each handle, and a rod having a hook secured to each outer rail said hooks adapted to be placed in any one of the holes in the respective plates.

2. In a harrow, a center rail having downwardly extending; teeth and to which a team may be hitched, a double eye plate carried by the center rail on each side thereof near the front end of the same, toothed rails hinged to the eyeplates and extending rearwardly and outwardly from the hinged rails horizontally with respect to the center rail, center rail, means to move the said hinged rails vertically and means to adjust the outer of the side rails with respect with respect to the center rail, and means to adjust said to the inner one. rails horizontally with respect to the side center rail. In testimony whereof I have hereunto set my hand this 5 3. In a harrow, a center rail having downwardly extend 1st day of May at Healdsburg, CaL, in the presence of the 15 ing teeth, a double eyeplate carried by the center rail on two subscribing Witnesses.

each side thereof near its front end, toothed rails hinged NICHOLAS A. SEIPEL. to the eyeplates and extending outwardly and rearwardly Witnesses: from the center rail, means to move said hinged rails ver- FRANI{ A. MADEIN,

1O tically with respect to the center rail, means to adjust the ORLANDO NAYLOR.
