. T (LZZ whom it may concern.-

Be it known that I, WILLIAM L. ORAN, a

resident of Kingston, Roane county, Tenvators, and more particularly to the clips or devices employed to secure the teeth, knives, or cultivating-shovels to the tooth-bars or other portions of the implement.

The object of the invention is to provide means whereby the teeth, knives, or cultivating-shovels may be easily and securely fastened to the tooth bar or frame of the implement, the several teeth or shovels being arranged on said frame in the best order for pulverizing the soil to prepare it as a seedbed or to avoid disturbing the plants when used as a cultivator.

With these objects in view the invention consists of a tooth or shovel supporting beam or bar combined with a tooth-clip, preferably reversibly and adj ustably secured to said beam or bar and provided in its upper and lower sections with a plurality of tooth-seats, whereby the teeth may be secured in a vertical position or with an inclination to either side of. the vertical, as may be desired.

Furthermore, the invention consists in certain details of construction and arrangements of parts hereinafter described and then pointed out in the claims.

The inventive idea involved may receive various mechanical expressions, one of which I have illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of a tooth-bar,

l showing the teeth secured thereto in various side elevation of the clip with the tooth and positions by my improved clip. Fig. 2 is a here shown as part of a harrow, though it is i obvious that it might be a similar bar in a cultivator orother similar implement. Toothclips 2 embrace the tooth-bar 1 and extend above and beneath the bar and some distance forward of the same, the projecting side portions 3 being each provided with a plurality of tooth-receiving holes or perforations 4, while the clip is provided through the yoke or rear portion 5 with a screw-threaded opening 6, within which a set-screw 7 works with its inner end bearing against the face of a flanged washer,the back of which rests against the tooth-bar. Each of the clips is provided with a plurality of tooth-receiving openings 4, both above and below the tooth-bar. Preferably the openings in the upper and lower side 3 of the clip 2 are in alinement, so that a tooth, if desired, may be passed through one opening above and opening below and the setscrew adjusted so as to draw the tooth back firmly against the face of the tooth bar, thereby securing the tooth and the clip in position. The teeth may, if desired, be passed through the openings 4., that are in vertical alinement in the upper and lower segtions of the clip, as shown by the central tooth in Fig. 1, or they may be inclined at a greater or less angle to one side or the other by passing the teeth through holes that are not in vertical alinement. For the purpose of accommodating the teeth when so inclined the side faces 8 of the openings dare or may be beveled, as indicated in Fig. 6. The clips may be integrally formed of a single piece of metal bent into U shape, with the hole 6 for the screw 7 through the yoke or back of the clip. I prefer; however, to form it with the back 5 and the sides 3 separated and suitably united in the following manner: The back piece 5 has cutaway shoulders 9, on each of which is a rearwardly-projecting pin 10, while the sides 3 have inwardly-projecting lugs or arms 11, provided with holes through which the pins 10 pass when the parts are assembled, as shown in Figs. 1 .and 2. If desired, the pins 10 may be upset, so as to form rivets to hold the parts firmly together. With this construction the reaction of the screw 7' against the tooth-bar draws the sides 3 rearward, and thus holds the tooth closely against the tooth-bar. It will be understood that the teeth and clips may be adjusted longitudinally to any desired position on the tooth-bar and that thus the teeth on the position to pulverize the soil or in rows in order to cultivate rows of plants. Furthermore, these rows may have the teeth all vertical or all slanting, or some vertical and some slanting, and the slanting teeth may all slant in the same direction or some in one direction and some in the other. In short, the position on the tooth-bars and the slant of the teeth are entirely within the control of the operator, and adjustment thereof'may combination of a tooth-beam, a tooth-receiving clip supported thereon, and a plurality of tooth-receiving openings or perforations in theupper and lower members of said clip, whereby the teeth maybe inclined to the left or the right in said clip, as may be desired.

3. In a harrow or other implement, a toothbeam, a tooth-clip composed of upper and lower members and a back member, means detachably securing said members together, a plurality of tooth-receiving openings in said upper and lower members and a setscrew passing through said back member and reacting against said tooth-beam.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses. 1
