To all whom it may concern:

Be it known' that 1, WILLIAM S. Barons, a

Q citizen of the United States of America, re-

siding at Kopperl, in thecounty of Bosque and State of a-exas, have invented certain new and useful Improvements 'in Self- DumpingDrag-Harrows, of which thefollowing is a specification, reference being had therein'to the accompanying drawing.

. This invention relates to harrows, and has for its objectthe production of asimple and V eflicient harrowwhich is constructed of a minimum number of parts and which may,-'

therefore, be manufacturedkat a minimum CO'St. 1 1 a 'Another object. of this invention is the production of-a simple and eflicien't means for elevating the harrow and turning the teeth of the harrowto such a position as to allow the accumulation which has been gathered thereby to be readily removed therefrom.

With these and other objects in view, this invention consists of certain-novel constructions, combinations and arrangements of parts as wil-lbe fully brought'ou't in the following specification. 7 In the drawings, Figure 1 is a top plan view of the harrow. Fig. 2 is a side elevation thereof. Fig. 3 is a rear view of the harrow. Fig. 4 is a central section taken along the line 4 4: of Fig. 1. r Fig. 5is a longitudinal section through one of the harrow tooth bars. Fig. 6 is a detail perspective of one of the supporting side members of the main frame of the truck which supports the harrow. Fig. 7 is a detail perspective of-a portion of one of the harrow tooth supporting bars showing an operating link connected thereto. Fig. 8 is a transverse section through the operating lever showing the manner of attaching the operating rods to said lever. Fig. 9 is a detail perspective of the quadrant used in connection with the present device. Fig.10 is a detail perspective of the axle of the harrow. Fig. 11 is a detail perspective of one ofthe quadrant supporting brackets. Fig. 12 is a section taken on the line 12-12 of Fig. 5.

By referring tothe drawings, it will be seen that 1 designates the main axle which is supported by means of'the wheels 2. A

harrow supporting frame 3 is'pivotally connected to the axle 1 by means of the pivot pins'i. The harrow supporting frame. 3

comprises a pair of parallel bars, and each sEIir-nUMrING DBAG HARBQW.

row bars '17.

5, whichend fits into the socket portion 6 of the central longitudinally-extending frame beams 7 of the harrow.

l A. transversely-extending brace "8' is secured to the side membersof the frame 3 and; constitutes an efficient means for holding these sideiv members in spaced relation. A quadrant supporting bracket 9" engages the axle 1, andthisbracket supports a quadrant 10. An "operating lever 11 is pivotally mounted upon the bracket 9 and this operating lever 11'is providedwith a spring catch- 12 forengagingthe'quadrant 10 and holding the lever 11in set position. A seat 13 of :iany-desirediconstruction' is carried by the axle so aslto allow the operator :tobe in a position to have free access tothe operating lever 11. a

-. A plurality of harrows 14: are carried in front of the frame 3- and the frame 3 is se-l cu'redto the harrows by having the offset 2611618 5 engagingthe loop portions :6 of the central frame bars 7 ofzthe harrow as above described. Agpair of side framebars 15 is carried by each-harrow and eachofthe b'ars I 7 Y and 15 is provided with a plurality of apertures 16 through which the harrow bars 17 pass. The harrow bars 17 comprise a substantially U-shaped body through which of theseis provided with an -offset end the harrow teeth 18 extend by having their I threaded ends19 passing throughthe har- Bolts 20 are placed upon the threaded ends of the teeth 18 for firmly holding the teeth18 in engagement with the harrow bars- 17. The forward ends of i the side bars 15 are provided with hook por-j l tions 21 which are engaged by the rings 22 of a draftbar 23. This draft bar, 23'may be attached to anydesired draft means.

The centrally located harrow bar 24 of each harrow carries a pair I of segmental runnersv 25, which runners comprise substantially two-thirds of a circle, and are held in engagement with the bars 24 by means of the transverselycxtehding bolts 26 passing through'the'hubs 27 of the run ners 25 and through the bars 2 1.

The transversely extending bars 17 of each harrow are provided with upwardly-extending links orfingers 28 which are connected to a common operating link 29 for the purpose of rotating the bars 17 and 24: simulta- I neouslyi The bar 245is prov'ided'with along connecting link 29, and: this link 30 is in I link 30' which is pivotally secured to the "position shown in dotted lines in Fig. 2, the

runners will be rotated and by coming in contact with the ground the harrows 14 will be elevated to the position shown in dotted lines and the harrow tooth supporting bars 17 and 24 will be swung so as to cause the harrow teeth 18 to be rearwardly inclined, thereby allowing the accumulation which has been gathered by the harrow to be removed or dropped therefrom. By again operating the lever 11 to the position shown in full lines, the harrow may assume its normal position and it should be understood that by moving the lever 11 to an adjusted position, the angle of the teeth 18 may be regulated at the will of the driver of the machine or harrow.

From the foregoing description, it will be seen that a very simple and eflicient means has been produced for changing the angle of the harrow teeth and at the same time elevating the harrow body without a great amount of effort on the part of the operator of the machine in view of the fact that the runners 25 will assist the operator in raising the harrow, for as soon as the runners have been thrown into engagement with the ground, the forward movement of the harrow will cause the runners 25 to further rotate thereby assisting the operator in elevating the harrow to the desired position. Merely by throwing the catch 11 into engagement with the quadrant, the runners 25 may be held in a set position.

Having thus described my invention, what is claimed is r In a device of the class described the combination with a harrow supporting frame, said supporting frame consisting of a pair of arallel bars, eachof said bars having an offset end, a pair of frame beams, socket portions carried at theirear end of said frame beams, harrow bars carried by by said beams, said ofiset ends fitting into said socket portions, and an'aXle supporting said supporting frame, runners carried by said harrow bars, and means engaging said runners for bodily raising said harrow bars upwardly.

In testimony whereof I hereunto aifix my signature in presence of two witnesses.
