PATENT JAMES HERVA JONES, OF ROCKFORD, ILLINOIS, ASSIGNOR TO EMERSON, I TALGOTT & COMPANY, OF SAME PLACE.

WAL-KlNG-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 374,538, dated December 6, 1887.

Application tiled July 7, 1887. Serial No. 243,645. (No model.)

To all whom, it may concern.-

Be it known thatI, JAMES HERVA JONES, a citizen of the United States, residing in the city of Rockford, county of \Vinnebago, and

3 State of Illinois, have invented certain new and useful Improvements'in Walking-Cultivators,

- of which the following is a specification.

This invention relates to cultivators of a class known as the straddle-row walkingro cultivator, in which a supporting frame mounted on carrying-wheels and independent shovel-gangs are employed to cultivate the op"- posite sides of a row of plants at the same operation. v

The object of my invention is to improve this class of'agricultural implements, to produce a more efficient machine of its class'at a reduced cost, and to lessen the labor of an attendant in handling the machine.

To this end I'have designed and constructed the improvements represented in the accompanying drawings, in which Figure 1 is an isometrical representation of portions of a cultivator embodying my invention; and Fig. 2 is a side elevation,partially in section, and showing the elevated position of the shox-etbeams.

The supporting-frame ofvrny improved cultivator, consisting of the crank-formed axle composed of the crowning portion 1, vertical arms 2, axle-arms 3, on which carrying-wheels are mounted, the tongue 5, and brace-rodsvti, constructed and joined to each other in the manner shown, also the horizontal 'evener 7 and the vertical arms 8 of the evener, their connections with each other, with the tongue, and with the crank-formed axle, are substantially the same as like parts of cultivators of its class nowin use, and are employed in substantially the same manner and for the same purpose.

A tubular draft-bar, 9, is provided with end arms, 10, projecting at a right angle there.

from, and their projecting ends are perforated to receive the draft-arm portion of the axle, on which they are mounted to oscillate freely.

Shovel-beams 11, which are of the usual on rved form, are joined at their forward ends to the opposite sides of the rear end of a jointyoke, 12, which is provided with forward- .eal ears.

projecting yoke-arms 13 on its upper andlower sides, and their forward ends are perforated to receive a vertical joint-bolt.

Olasp-bars 14 have their forward end portions made to embrace the tubular draft-bar forward of the axle, and a clamping-bolt, 15, is passed through their projecting ends forward of the tubular draft-bar. The rear ends of the clasp-bars'embrace the forward ends of the jointyoke arms, anda joint-bolt, 16, passed through the parts, serves to connect the claspbars and joint-yoke in a free manner to permit a lateral swinging movement of the shovelbeams, and by means of the clamping-bolt 15 the clasp-plates are made to embrace the tubu- 6 5 lar draft-bar firmly to cause it to oscillate on the axle in the vertical movements of the shovel-beams.

This construction of the tubular draft-bar and the clasp-bars and their clamping-bolt connection with the draft-bar provides the means for the lateral adjustment of the shovel-gangs toward or from each other to cultivate closer to or farther from the plants, and it also provides the means for the vertical adjustment of 5 the forward ends of the shovel-beams to cause the shovels to run ata greater or less depth in cultivating, all of which will be readily under stood by an inspection of the drawings. I

A stretcher, 17, is fixed between the rear portions ofthe shovel-beams, and vertical ears 18 rise from its central portion. An'angle-lever, 19, is j ournaled' to oscillate on a bolt passed through the upper end portions of the verti- A curved link, 20, is hinge-jointed to the free endof the short arm of the anglelever, and a spring, 21, connected at; its rear end to the free end of the curved link, extends forward between the shovel-beams and is connected at its forward end to a hook, 22, depending from the under side of the joint-yoke.

A link, 23, connects the free end of the long arm of the angle-lever to an arm, 2i, projecting laterally outward from the upper portion of the vertical arms of the axle. Thelateral projecting arm, 24, is'provided with a semisleeve base, 25, to embrace the outer face of the vertical arms of the axle, and ears 26 inclined to the sleeve projecting from its opposite sides.

v A steady-brace, 27, is placed on the'inn'er face of the vertical arms of the axle against the inclined ears of the semi-sleeve 25, and bolts passed through the ears and through the upper end of the brace serve to fix the parts in place.

The brace 27, from its connection with the axle, extends rearward and downward to place its rear forked end, 28, in position to receive the shovel-beam when elevated, to prevent lateral swaying in transportation.

The construction and application of the an gle-lever 19, curved link 20, spring 21, and link 23 and their connections are such that, when the shovel-beams are depressed to a point to carry the draft-line of the spring above the center of the journal-bolt of the angle-lever, the action of the spring will tend to depress the shovel-beams still farther, and is limited in this downward action by the curved inner surface of the curved link engaging the hub of the angle-lever, and when. the shovel-beams are elevated to a point to place the draft-line of the spring below the center of thejournalbolt of the angle-lever the action of the spring will tend to elevate'the shovel-beams and hold them in engagement with the forked end 28 of the inclined brace-bar 27, as shown in Fig. 2, to carry them elevated, and from which position they can be readily detached and lowered to their working position, as shown in Fig. 1, by a downward pull on the handles.

The handles 29 are of the usual construction, and in their connection with the shovel beams any of the known methods may be employed.

A link; 30, is employed to connect the sin gletree 31 to the vertical arm of the compound evener, and its rear end is pivotally connected to the vertical arm of the evener, and is made vertically adjustable in its connection therewith by means of a series of holes formed in the vertical arm, and a brace-arm, 32, depending from the under side of the link to engage the forward edge of the vertical arm, serves to limit the downward movement of its forward end to supportthesingletree connected thereto clear of the wheel.

In the accompanying drawings I have only represented such parts of a cultivator believed necessary to illustrate my improvements, and have limited the foregoing description to the parts shown; but the parts necessary to a complete cultivator of its class not shown nor herein described, and not duplicates of the.

draft-bar provided with laterally-extending arms which loosely embrace the axle, of the joint-yoke of the shovel-beams, the clasp-bars having recesses at their forward ends to partially embrace the draft-bar, and bolts, one to hinge the joint-yoke to the clasp-bars and one to lock the forward ends of the clasp-bars to the draft-bar, substantially as set forth.

3. The combination, with the shovel-beams and with the axle, of an angle-lever journaled to the shovel-beams, a link'and-spring connection of the angle-lever with the forward portion of the shovel-beams, and a link-connection of the angle-lever with the axle, operating to depress or elevate the shovel-beams, substantially as and for the purpose set forth.

4. The combination of the axle, a semisleev'eto embrace the axle, a lateral arm projecting from the semi-sleeve, and a steadybrace to the shovel-beam, said steady-brace serving as a clamping-bar to the semi-sleeve, substantially as and for the purpose set forth.

JAMES HERVA JONES.
