HARROW-TOOTH HOLDER.

QPEGIFICATION forming part of Letters Patent No. 344,804, dated July 6, 1886.

Serial No. 169,116. (No model.)

T0 at whom it may concern.-

Be it known that I, J osnrn ELLIs BEEBE, a citizen of the United States, residing at Adair, in the county of Adair and State of Iowa, have invented certain new and useful Improvements in Harrow-Tooth Holders; and 1 do declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to harrow-tooth-holding devices; and it has for its objects, first, a holder for securing the tooth in place and permitting an oscillatory movement thereof, said holder being readily attached and detached from the tooth supporting bar; second, a holder for securing a tooth to its bar, so that when the latter is moved in one direction the tooth will stand obliquely to its supportingbar, and when drawn in the opposite direction will stand at nearly right angles thereto, said holder being made reversible, and also adapted to be inverted to change the position of the tooth, as desired.

The invention by which these objects are obtained consists in the combination, with a bar having a notch in its side, of a block or holder transversely apertured to receive the bar and vertically apertured to receive the tooth, the two apertures running at right angles to each other and partially intersecting, the upper and lower walls of the transverse slot through the holder extending part way in a horizontal plane, or at right angles to the tooth-receiving aperture, the remaining portion inclining away from said horizontal portion, the diagonally-opposite portions of the walls being made to correspond, as clearly V of a harrow-bar provided with my improverow-tooth bar provided with two holders oppositely mounted thereon.

The same letters refer to corresponding parts in the various figures.

A section of tooth-supporting bar, A, is notched on its sides, as at a.

The tooth-holder B is transversely slotted, as indicated at b, and vertically apertured, as represented at (Z, said openings preferably extending at right angles to each other, and partially intersecting, as most clearly shown in Figs. 3, 5, and 6. These openings b and (Z correspond to a cross-section of the tooth-bar and tooth, respectively, the former being preferably rectangular, although any desired shape may be employed. The upper and lower walls of the opening I) are formed on difi'erent planes, a part, e, extending at right angles to the aperture d, the remaining portion f in clining away from the horizontallyextending part. The inclined portion of the wall on the one side is directly oppositethe horizontal portion of the diametricallyopposite wall, thus bringing the corresponding parts of. the walls diagonally opposite to each other, as

more fully shown in Fig. 4. The plain surfaces of the walls 6 and f are united. by a converted curving surface, t, which is found to give better results, and the wear on the beam is not so great as it would be if the walls 6 and f met on a straight line, thus presenting an angular projection.

The side walls of the notches c in the toothbar are similarly formed to the upper and lower walls of the openings Z) through the holder.

In practice the harrow is constructed so that its bars may be easily and readily detached and replaced in order to better carry out my invention. The holder 13 is sleeved or passed over the bars with its vertical aperture adjacent to and coinciding with the notch in the bar, when a tooth is passed through the vertical aperture in the holderand locks the parts in position, there being sui'iieient play to permit the free oscillation of the tooth and holder in a direction lengthwise of the bar.

The teeth may be held in placein the holder in any well-known manner; but the way shown is preferred, the tooth being made tapering and the aperture of a corresponding IOC shape, this being the simplest and most inexpensive method.

It will be seen that the holder may be inverted without changing its relation or that 5 of the tooth to the bar, provided the tooth'remains on the same side of the bar, while reversing the holder and changing the tooth to the opposite side of thebar reverses the position of the tooth and holder, as best shown in Fig. 9.

It must be observed that in cases where it is designed that the holders should be inverted without changing the relation of the tooth to the bar the toothis made of uniform diameter to within a short distance of its pointed end, and the vertical aperture through the holder is likewise of a uniform area corresponding tov the tooth, the latter being secured in place in any well-known manner which will readily suggest itself to a skilled mechanic.

In Fig. 1 a form of holder. isshown, partly in dotted lines, in which vertical apertures extend on either side of the transverse opening, the reversing of which, the tooth remainz, ingon the same side of the bar, changes the relative position ofthe tooth.

From the foregoing the operation of the tooth and holder will readily be understood. As the bar is drawn in one direction, (repre- 0 sentedby the arrow, Fig. 4,) the inclined walls.

f of the holder will contact with the upper and lower face of the tooth-bar and hold the same audits toothin anoblique or inclined position, while. a reverse motion will cause the 5 shifting of the holder, and the horizontal portions of said walls will contact with the upper and lower faces of the tooth-bar and hold. the tooth in avertical position.

Having thus described my invention,what I claim, and desire to secure by Letters Patent,

1. A harrow tooth holder formed in one piece having a vertical opening to receive the tooth and a horizontal opening to receive the 5 beam, and adapted to rock upon the beam, to

permit. the tooth to automatically shift from a vertical to an inclined position, 'or vice versa when the draft is reversed.

2. The combination ofa notched bar, a holder provided with partially-intersecting vertical and transverse apertures, each surface of the upper and lower walls of the transverse aperture extending part way in a horizontal and part way in an inclined direction, the ina harrow-tooth holder consisting of a casting provided with a vertical and transverse aperture adapted to receive the tooth and beam, respectively, the transverse aperture having its upper and lower surfaces or walls each provided with a horizontal and an inclined surface, the said horizontal and inclined surfaces being arranged at opposite ends of the aperture, substantially as and for the purposes set forth.

4. In combination with the barrow-beam, the. tooth-holder wholly inclosing the latter, and having the opening through which said barrow-beam extends inclined or tapered from one end of said tooth-holder, as set forth.

5. In a harrow, a tooth'holder formed in a single piece having a vertical opening to receive the tooth, with means for adjusting the latter therein, and a horizontal opening to receive the beam, and adapted to rock upon the beam to permit the tooth to automatically shift from a vertical to an inclined position, or vice versa when the draft is reversed.

6. In a harrow, the combination of the single flat beam and apivoted t0oth-holder consisting ofv the two frames at right anglesto each other inclosing the tooth and beam, respectively, the frame of the latter having its opening diminished in longitudinal width, to allow the tooth-holder to partially rotate on its pivot and the tooth to incline automatically, as set forth.

In testimony whereof Iaffix my signature in presence of two witnesses.
