HARROW.

Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed September 29, 1908. Serial No. 455,290.

To all whom it may concern:

Be it known that I, STANLEY F. HORNER, a citizen of the United States, residing at Enid, in the county of Garfield and State of Oklahoma, have invented a new and useful Harrow, of which the following is a specification.

This invention has relation to harrows, and it consists in the novel construction and arrangements of its parts, as hereinafter shown and described.

The object of the invention is to provide a draft means for a harrow whereby sectional harrows do not have to be taken apart in transporting the harro'w from field to field, over roads and bridges, and through gateways.

A further object of the invention is to provide means for simultaneously swinging all of the tooth-bars in supporting bars, and to provide said swinging means with a lever which may be used at either the front or rear end of the harrow section, and which co6perates with means for holding the same in an adjusted position. By such an arrangement, when the harrow teeth are worn dull at one side, the harrow section may be reversed, or the rear end thereof may be connected with the draft means, and thus the sharp, or unworn side of the harrow-teeth may be presented to the work.

In the accompanying drawings: Figure 1 is a top plan view of the harrow. Fig. 2 is a top plan View, enlarged, of one of the harrow sections. Fig. 3 is a vertical sectional view of one of the harrow sections. Fig. 4 is a sectional view of one of the teeth-bars. Fig. 5 is a transverse sectional view of one of the supporting bars, showing the manner of connecting the same with the lever mechanism, and Fig. 6 is a detailed view of the coupling means between sections of the draft-bar.

The draft-bar of the harrow is made up of the intermediate sections 2 and the end sections 1. As illustrated in Fig. 1 of the drawings, three of such sections are used, but it is obvious that more or less may be employed if desired. In the assemblage as shown the end sections 1 are provided with the U-shaped irons 3, which are bolted at the ends of the said sections, while the section 2 is provided at its ends with the clamps 4, which are adapted to receive intermediate portions of the irons 3 in such manner that the sections 1 may swing vertically with relation to the sections 2, but cannot swing horizontally with relation to the same. The clamps 4 are held in position by means of the transversely disposed bolts 5 which pass through the sections 2, and it is obvious that by removing the said bolts 5 the clamps 4 may be separated, so that the sections 1 may be disconnected from the sections 2 if desired. Thus it will be seen that a sectional draft-bar is provided, and that the end sections 1 may be swung up over the intermediate sections 2, when desired. The draft rods 6 are connected at their rear end portions with the sections 1 and 2 respectively, and are connected at their forward ends with the ring 7. Each of the rods 6 is provided at an intermediate point with a universal joint or link connection 8. Each of the sections of the draft bar is provided with a series of eyes 9, which project rearwardly. A harrow section is attached to each of the sections 1 and 2 of the draft-bar.

Each harrow section consists of the supporting bars 10, which are located at the sides of the harrow section and the intermediate supporting bar 11. The said supporting bars 10 and 11 are in parallel relation and are braced by the diagonally disposed braces 12. The bars 10 are provided at their front and rear ends with the hooks 13, which are adapted to engage the eyes 9 carried by the draft bar sections 1 and 2. The hollow teeth-bars 14 are journaled for rotation in the supporting bars 10 and 11 and pass transversely through the same. The said bars 1.4 are provided with the perforations 15, which are adapted to receive the harrow spikes or teeth 16. The hollow tubes 17 are located within the hollow bars 14, and also have perforations 18, which correspond with the perforations 15 and which also receive the harrow teeth 16. One end of each of the inner hollow bars 17 is threaded as at 19, and a nut is screwed upon the said threaded portion 19 and is adapted to bear at its inner face against the end of the outer hollow bar 14, and thus, after the teeth 16 have been inserted through the perforations 15 and 18 of the two bars, the nut20 may be tightened up against the end of the outer bar whereby the inner bar will be moved longitudinally with relation to the outer bar and the said spikes will be gripped or secured between the edges of the perforations 15 and 18 of the two bars. The said teeth 16 are preferably provided at soil at a desired angle.

their upper ends with the heads 21, whereby the said teeth are prevented from falling through the perforations 15 and 18,- should the inner bar 17 move accidentally with relation to the outer bar, while the harrow is in operation.

A vertically disposed arm 22 is attached to each of the bars 14 at an intermediate point thereof, and the bar 23 is pivotally connected with the upper ends of all of the arms 22. The arms 22 at the front and rear of the harrow sections are provided with perforations 24 which are adapted to receive the lug 25, carried at the lower end of the operating lever 26. provided with a bolt 27, which is adapted to serve as a pivot between that arm 22 with which the said lever is connected, and the bar 23. vided at its end portions with the perforations 28 which are adapted to receive the lugs 29 of the gear segment 30. The bolt 31 may also be passed through the said gear segments 30 and the intermediate bar 11. The lever 26 is provided with a spring pawl 32, which is adapted to engage the segments 30. Thus it will be seen that by swinging the lever 26 the arms 22 will be rocked, which, in turn, will turn the bars 14 axially, and the teeth 16 may be presented to the When the teeth have become Worn at their forward edges the hooks 13 at the rear ends of the sides of the harrow sections may be engaged with the eyes 9, whereby the unworn edges of the teeth 16 will be presented to the work. When the harrow section is reversed with relation to the draft bar as above de- The said lever 26 is- The intermediate bar 11 is pro-- scribed, the lever 26 and the gear segment 30 are transferredto the rear ends of the harrow section as indicated. The said segment 30 is provided at its loWer ends with the two lugs29, as shown in Fig. 5, which permits the said segment to be turned so that it may be applied to the inner end portion of the intermediate bar 11 as indicated.

Having described my invention, what I claim as new, and desire to secure, by Letters Patent, is

In a harrow as described, a series ofjour naled teeth-bars, arms attached to the said bars, a connecting bar pivotally attached to the ends'of the said arms, a supporting bar for the teeth-bar, said supporting bar having in the vicinity of its front and rear ends perforations, a gear segment having at one end laterally disposed lugs which are adapted to enter the perforations in the said supporting bar, bolts passing transversely through the said gear segment and said supporting bar, the end arms being provided with perforations, and a lever having at its lower end a lug adapted to enter the perforations in the end arm, said lever being provided with a pivot belt which is adapted to serve as a pivot for the arm to which it is connected and the connecting bar between the arms.

In testimony that I claim the foregoing as .my own, I have hereto affixed my signature in the presence of two witnesses.

STANLEY F. HORNER.
