WEEDER-TOOTH.

SPECIFICATION forming part of Letters Patent No. 738,477, dated September 8, 1903. Application filed July 23, 1902. Serial No. 116,637- (No model.)

To all whom, it may concern:

Be it known that I, ALBERT J. PATTON, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Weeder-Teeth, of which the following is a specification.

This invention relates to an improvement in Weeder-Teeth and to the fastening means employed to secure the same to the tooth-bar.

One of the objects of my invention is to provide aweeder-tooth which shall be sufficiently elastic to allow of its use without injury to the growing crops and which will be withal so constructed that it will be stiff enough to prevent any side twisting. a

A further object of my invention is to provide a simple and efficient means for securing the weeder-tooth to the'tooth-bar.

In the accompanying drawings, wherein a preferable embodiment of my invention is shown and wherein like numerals of reference refer to similar views in the several parts, Figure 1 is a perspective view of my improved weedertooth secured to the tooth-bar. Fig. 2 is a rear elevation of the same. Fig. 3 isa transverse section of the tootl1-bar, showing the wecder-tooth and the means employed to secure the same in side elevation. Fig. 4 is a bottom plan view of the tooth-bar with the tooth secured thereto, and Fig. 5 is an e11- larged view of the upper-part of Fig. Referring now more particularly to the drawings, B indicates the tooth-bar, preferably formed of angle iron, to which the weedertooth O is adapted to be secured. The weeder-tooth O is preferably constructed of two rods of steel having their lower ends welded together and drawn out to a point. The upper free ends of the tooth C are formed with the downwardly-bent portion a. The tooth-bar B is provided at'the point where it is desired to secure the weeder-tooth with two apertures I) b,which are adapted to receive the free ends of the weeder-tooth O. A third aperture is formed in the tooth-bar between the openings b'b, but nearer the bottom of the tooth-bar. This opening is designed to receive the bolt used to secure the clip which fastens the tooth-bar, as will be hereinafter more particularly set forth.

To secure the tooth O to the tooth-bar B, I employ a clip D, fastening-bolt A, and nut E. The clip D is adapted to stand astride the bent portions 0 of the tooth C after they have been inserted in the holes I) b. of the tooth-bar B. The clip D is constructed with a central aperture adapted to loosely receive the end of the bolt 'A and at each side of said aperture with grooved portions'cl, adapted to fit over the bent portions 0 of the tooth O.

n 0 w From the above descrlption of the parts y it will be seen that to secure the tooth to the tooth-bar it is only necessary to insert the free ends of the tooth O in the aperturesb and I) of the tooth-bar, so that the bent-overportions 0 of the tooth will lie along the front edge of the tooth-bar, place the locking-bolt A in the tooth-bar from the rear side with its end projecting between the bentover portion 0 of the tooth O, slip the clip D on the projecting end of the bolt A, and by means of the nut E, secured on the end of the bolt A, advance the clip D until the bent-over portions 0 of the tooth O are clamped firmlybetween said clip D and the front edge of the tooth-bar B.

In manufacturing my improved weedertooth I may employ either one of two methods-namely, I may make the tooth of two separate rods by welding them at one end and drawing that end into a point, or Imay make the tooth out of a single rod by taking a rod of about twice the length which it is desired the tooth should be, bending it at its center, welding the two parts together for a short distance above the bend, and drawing out a point at the bend.

I do not desire to limit myself to the precise form and construction shown in the drawings, as it is obvious that many minor changes might be made thereto without departing in the least from the spirit of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. A weeder-tooth consisting of an upper portion of two separated rods and a lower portion of a single rod drawn out to a point.

2. A weeder-tooth consisting of two rods separated at their upper ends and connected at their lower ends to form a point.

3. In a weeder, the combination with a toothbar, of a weeder-tooth consisting of two rods separated at their upper ends and connected at their lower ends to form apoint, and means for attaching said tooth to the tooth-bar.

4. In aweeder, the combination with a toothbar, of a weeder-tooth consisting of two rods separated at their upper ends and connected at their lower end to form a point, and a clip for attaching the upper separated ends of the tooth to the tooth-bar.
