RIDING-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 431,980, dated July 8, 1890.

Application filed February 13, 1890- Serial No. 340,327. (No model.)

To alZ'whom it may concern.-

Be it known that I, JAMES IIERVA JONES, a citizen of the United'Stat-es, residing at Rockford, in the county of Vinnebago and State of Illinois, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to a class of cultivators employing parallel swinging drag-bars,

IO and employed in connection with a supporting-frame carrying a drivers seat and the nec essary adjusting devices.

The object of this invention is to construct a drag-bar having a rear section pivoted thereto, said section extending obliquely to the dragbar, thus forming a support for two shovels.

A further object is to construct a drag-bar and rear section with cross-ribs, forming aseries of truss-bars to resist transverse and torsional strains.

The further object is to secure the inner shovel to the rear section by the employment of a bracket entering a socket and held in 2 5 place by a bolt.

The further object is the application of a single spring acting to lift the drag-bar and hold the lifting-lever in engagement with the toothed segment.

The further object of this invention is an adjustable bail for quickly and easily adj usting the width of the beams in relation to each other.

In the accompanying drawings, Figurel is 3 5 an isometrical represention of such portion of a cultivator as I deem necessary to illustrate my improvements. Fig. 2 is an isometrical representation of one arm of the adjustable bail. Fig. 3 is an isometrical representation of the rear section of the drag-bar, showing the socket which receives a bracket for holding the inner shovel-standards in position. Fig. 4 is an isometrical representation of the bracket employed to hold the inner shovelstandard in position. Fig. 5 are side elevations of the forward part of the drag-bar,

showing the construction of the ribs on each side.

The parts of a complete riding-cultivator 5o (notherein shown) may be of any of the known varieties, and I deem it necessary to show only such parts within which my unprovements have a close connection.

I have constructed a lifting device for the purpose of raising the beams or drag-bars to disengage the shovels from the ground. The beams are partly lifted by the hand-lever 1 and partly by the bar-spring 2. This barspring 2 is made to serve two purposes byits teusionnamely, that of lifting a consider 6o able part of the beam and also that of holding the hand-lever 1 in engagement with the teeth of the quadrant 3 when required. This object is attained by placing the spring 2 in such a position that its free end will move in a plane obliquely in relation to the plane of the movement of the hand-lever 1. With the free end of the bar-spring 2, connected to the hand-lever l by the hook 4 on the opposite side of the fulcrum 5 from the teeth 6 of the quadrant, the spring expends a part of its force in raising the beams through the intervention of the suspension-rod 7 between the lever and the beam. The spring, also, by virtue of its oblique position, draws outwardly in opposition to the plane of the quadrant, and as a result that part of the lever on the opposite side of its fulcrum is drawn inwardly toward the quadrant. Thus the teeth of the lever and the teeth of the quadrant are held in engagement. The flexibility of the spring allows the lever to be disengaged from the quad rant when it is required.

All straddle-row, riding, and combined cultivators are provided with bails or sway-bars for the purpose of holding the beams and the shovels a proper distance apart on each side of the row of plants. They are arched to allow tall plants to pass beneath. The shovels are required to be adjusted to different widths between them, according to the size of the plants. This has usually been done in an imperfect and unhandy manner. Iconstruct a bail with what may be properly called an instantaneous adjustment, by means of which the beams and shovels can beinstantly set to or from each other. I attain this re sult by making the bail in two parts or halves 8, which may be duplicates. The tops 9 are segments of a circle. Each part has a nipple 10o 16 upon its surface anda slot 11 near its end. The two parts are placed upon each other with the nipple of one part in the slot of the other and secured with a washer on the end of each nipple and a rivet 12 through it. The two parts will now slide freely upon each other around an imaginary center of a circle. The circular motion will expand or contract the lower ends of the bail in relation to each other. When the two beams are attached to these lower ends in any preferred manner, they will expand or contract as the bail is adjusted.

To secure the bail and hold the shovels in any required position I provide projections or lugs 13 at the crown of each arch on the outside of each part, which are placed radially with the imaginary center and at equal distances apart. A bifurcated clip or double key 14 is prepared, and when any of the two spaces between the lugs on the bail areeoincident with each other on each side, the key is thrust down with a leg in a space on each side and the bail with the shovels are held firmly in position. sition it is only necessary to lift the key 14 and place it in any other two coincident spaces. It is evident that if the lugs 13 were formed on the inside surfaces of the two parts of the bail instead of on the outside and a single key instead of a double key 14 was inserted in coincident spaces the same result would be attained. The bail is held in an upright position by attaching the key 14 in a free manner to one end of a brace=rod 15, while the other end is attached in a free manner to the frame of the cultivator.

My improvements of the beams 'or dragbars 16 relates to that class called parallel beams, wherein the rear sections 17, to which the shovels are attached, are hinge-j ointed to the forward sections 16 and the hinge 18 e011- trolled by a jointed rod 19 parallel with the forward section. The object of the parallel beam is to hold the shovels with their faces at right angles tothe line of draft at all times when the beams are swinging from side to side. The ordinary method of constructing such beams is with a T-head or cross-head hinged to the rear end of the forward section and held in free jointed position by a parallel rod. To attach the shovels to this cross-head, with one shovel leading the other, as required in practice, it is necessary to provide one straight standard and one crooked standard for them.

The purpose of my improvement herewith is to provide a substitute for this cross-head constructed in a cheap and durable manner, and adapted to allow a pair of duplicate standards for the shovels to be used instead of difierent ones, thus saving a considerable expense and weight. I accomplish this by extending the rear section 17 of the beam 16 in a line oblique to the line of draft, from the hinge-joint 18 to the place where the perpendicular standard 21is attached. This strong To change to another po-' and simple form allows the shovelto be placed at a proper working distance sidewise from the longitudinal center of the beam.

To place the forward shovel a proper workin g distance on the opposite side of the longitudinal center of the beam, I provide a boxbracket 22 of novel form projecting inwardly from the beam. My invention herewith consists in the peculiar method of attaching this bracket to the rear section 17. In the side of the beam I make a recess 23 of rectangular or box form, and the inner end of the bracket 22 is also of box form, the size of which is the same on the outside as the recess in the beam is inside. The box of the bracket is made to enter the box in the beam in a closefitting manner. External shoulders 24 are formed on the bracket to limit its entrance into the beam. A bolt is passed through the beam, the bracket, and the shovel-standard, and all are secured firmly together. This is the strongest possible connection of two parts to resist the leverage of the shovel when working in the ground. It is my purpose to make the rear section 17 of the beam with the maximum strength and a minimum weight to resist the rearward and transverse leverages of the rear shovel. To this end the principal body of the section is formed of a thin web 26, with its surfaces in a perpendicular plane. This web is re-enforced on its upper and lower edges with wide flanges 27. \Vithin these flanges and upon the surfaces of the web are oblique ribs 28, which cross each other, forming a truss. Placed thus they are in the best possible form to resist the rearward strain of the shovel. The crossings of the ribs 28 on one side of the web are half-way between the crossings of the ribs on the other side, lengthwise of the section, as shown at Fig. 5. Thus the center of each rib on one side crosses the center of each rib on the other side. This arrangement of ribs produces a very powerful resistance to any torsional or transverse strains of the shovel, and has but little weight.

I construct the body of that part of the beam forward of the hinge-joint 18 in precisely the same manner as the rear section and for the same purpose, namely, with a thin central web 29, re-enforced on its upper and lower edges with flanges 30, and having between them oblique ribs 31, forming trusses. The ribs on one side of the Web are placed in relation to the ribs on the other side in the same novel manner as upon the extension 17 in rear of the hinge-joint.

It is evident that the truss-ribs above described may be applied to a drag-bar of but a single piece, as heretofore constructed, and in the claims where I speak of a drag-bar I mean a drag-bar composed of a single piece or of sections having its entire length or any of its sections provided with the truss-ribs.

I claim as my invention- 1. The combination of a drag-bar, a quad- IIO rant, a bar-spring attached to the quadrant,

its free end moving in a plane oblique to the plane of the quadrant, and a connection between the spring and drag-bar, substantially as set forth.

2. The combinationof a quadrant, a hand lever, a bar-spring attached to the quadrant, its free end moving in a plane oblique to the plane of the quadrant, and a connection between the spring and hand-lever, whereby the lever is held in engagement with the quad rant, substantially as set forth.
