UNITED STATES PATENT OFFICE.

' Application filed September To all whom it may concern:

Be it known that I, ROBERT L. NELLIs, a citizen of the United States, residin at Earlham, in the county of Madison and S tate of Iowa, have invented a new and useful Riding Attachment for Harrows, of which the following is a specification.

My object is, first, to connect four harrowsections direct to a drag-bar and evener in such a manner that the outer sections will be vertically adjustable relative to the inner sections; second, to connect a sulky direct .to the rear ends of the two inner sections in such a manner that by shifting the position of the driver on the sulky-seat the inner sections can be lifted as required to release rubbish gathered by the teeth; third, to provide means for adjusting the drivers seat; fourth, to connect treadles and crank-shaft with the outer sections, so thedriver can by footpressure, lift the outer sections as required to clean them; fifth, to provide a sulky-carriage adapted to be connected with the two inner sections in such a manner that it will be automatically adjusted relative to the line of advance by the movements of the inner har- Low-section.

My invention consists in the construction, arrangement, and combination of elements and subcombinations as hereinafter set forth,

- pointed out in my claims andillustrated in the accompanying drawings, in which Figure l is a top view that shows all the parts combined and their positions relative to each other as required for practical use. Fig. 2 is an enlarged view that shows the manner of hinging the stub-axles to the sulky, frame and also to the ends of the main axle. Fig. 3 shows means used for flexibly connecting the front end of the sulky-frame direct with rear ends of the inner barrow-sections. Fig. 4 shows the manner of constructing the sulky-frame and means for supporting and adjusting a drivers seat thereon. Fig. 5 shows the manner of connecting a crankshaft with a barrow-section for lifting and cleaning the barrow-teeth by means of footpressure. Fig. 6 is a rear end view of the sulky and shows the form of the axle and its connection with the toothed rear harrowbars of the two inner harrowsections. Fig. 7 is an enlarged view that shows the hinged connection between the front ends of an inner and an outer barrow-section and one end of the drag-bar and evener.

The numeral 10,designates the central or j Specification of Letters Patent.

inner barrow-sections, and 12 the outer sections. connected at its front corners with a straight rigid bar 13 by means of chains 14, as shown in Fig. 1, in such a manner that each section will have independent motion relative to the ground over which it is advanced. The bars 13, connected with the inner sections 10, are also flexibly connected with a drag-bar 15 by eyebolts 16 or in an suitable way, and the ends of bars 13 of the inner sections .10 and the outer sections 12 are hinged together as required to allow the outer sections 12 to be vertically adjustable relative to the inner sections 10. Braces 17, fixed to the outer end portions of the outer bars 13, are pivotally connected with the ends of the drag-bar 15 in such a manner that the braces will allow vertical adjustment of the outer harrowsections, as required to carry the outer sec tions inoperative and to allow the complete harrow to pass between gate-posts in moving in and out of a field.

An evener-chain 18 is fixed at its ends to the ends of the drag-bar 15 and its central portion extended over a pulley 19 in a bearer 20, fixed to the center of the drag-bar, as shown in Fig. 1, in such a manner that the chain will adjust itself to the force applied thereto by horses hitched thereto by means of doubletrees and swingletrees connected therewith.

The rear ends of the inner barrow-sections 10 and outer sections 12 are adjustably connected, by means of crank-shafts 21, in bearers 22 fixed to the parallel bars of the inner sections 10, as shown in Fig. 1, and to the rear and round toothed bars of the outer sections 12, as shown in Fig. 5, by means of clips 23 on said round bars and links 24 on the ends of the cranks 25, that extend rearward from the shafts 21 and are pivotally connected with the clips 23.

21 terminate in treadles 27 within reach of the drivers feet in such a manner that While the harrow is in motion he can by foot-pressure on the treadles operate the crank-shafts 21 as reuired to elevate s e. r sec ions so as o a ow rubbish gathered by c harrow-teeth tgiQLjhggefrMo clfitlimections 12.

1e su tifl' f afifipbed of two bars bent into shape to produce frames 28 and their inner ends placed in overlying position Patented Aug. 28, 1906.

Each section 10 and-12 is flexibly Cranks 26 on the inner ends of the shafts and riveted together, as shown in Fig. 6. To y the ends of the frames are jointly pivoted

bars

29 and 30 and stub-axles 31, as shown in Figs. 2, 4, and 6, by bolts 32 in such a manner that the

bars

29 and 30 will extend forward and downward, and the stub-axles outward.

The front ends of the

bars

29 and 30 and straight bars 33, having elongated slots, are connected by bolts that extend through said slots in such a manner that the bars 33 can slide back and forth said slots, and their front ends are pivotally connected with the rear toothed bars of the inner harrow-sections 10 by means of clips 34, as shown in'Fig. 4, and the rear ends of the bars are connected with the bars 29 by means of coil-springs 35, that allow sliding motions to the bars 33 and flexible connection'between the inner harrow-sections and the sulky.

a distance limited by A bar '36 is fixed to the front end portions of. the bars 30, and a spring-seat bearing-bar 37 is'fixed to its center at'its front end and to the center of a bar 38, fixed on top of the frames 28 of the axle. A seat 39 is slidabl connected with spring-bar '37 and a frame'40 fixed to the said spring-bar and a lever 41 fulcrume'd thereto and connected with the seat by a link 42 in such a manner that a person on the sulky can operate the lever as required for moving the seat backward or forward. A toothed side of the spring-bar 37 and a s tuated pawl 44, connected with the ever, detachably lock the lever as required to retain the seat stationary. 'By thus a djustably connecting the seat with the spring-bar 37 the operator can move the seat backward and forward as required to balance his weight, so that he can, by leaning backward, lift the inner barrow-sections to allow rubbish aecumulated on the harrow-teeth to drop therefrom.

Having thus set forth the purposes of my invention and the construction and function of each element and the arrangement and combination of all the parts, the practical operation and utility thereof will be readily understood by farmers and others familiar with the art to which it pertains.
