UNITED STATES ATENT FFIC HENRY M. GODFREY, OF JONESBURG, MISSOURI.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 386,702, dated July 24, 1888.

Application filed January 9, 1888. Serial No. 260,166.

To all whom, it may concern.-

Be it known that I, HENRY M. Gonranrpf J onesburg, in the county of Montgomery and State of Missouri, have invented a certain new and useful Improvement in Cultivators, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of this specification, and in which Figure I is a side view showing the pivotal frame that carries the shovels and its self-adjusting spring-support. Fig. II is a top view of the cultivator, and also shows a view from another standpoint of the pivoted laterallyadjustable shovclframes and their Vertical self-adjustment by the suspension'springs; and Fig. III is a perspective view of the shovelcarrier frame, showing its vertical and lateral means of attachment and the diverse position of its standard-bearer attachments.

The invention relates to that class of devices which provide means of adjustment and selfadjustment of cultivator-shovels, 850., through pivoted and spring suspended frames that carry the shovels; and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, in which similar figures of reference indicate like parts in all the views, 1 represents a CllltlVfltOl with my improvements attached. 2 is the arch-axle; 3, the wheels; i,the tongue; 5,the wooden braces between the tongue and axle-arch, to which said braces and the tongue are secured by clips 6, that are fastened by screw-nuts 7.

8 represents the shovel-carrier frame,whieh is of a compound pivotal construction with a spring suspension, so as to make it both ad justable laterally and vertically under the manipulation of the operator and selfadjusting vertically under the actuation of the springbow 9, to enable the shovels 10 to automati cally tend to a uniform depth ofinsertion,and thus in a great measure overcome the tendency to deviations in depth from variations in the surface lay of the land.

11 represents twin journal-cli ps, that are constructed in pairs and embrace the axle with loose bearings in front of the shovel-carrier frames, which they carry.

12 are draft-clips, that rigidly embrace the (No model.)

- lower level of the axle alongside the journalclips. These draft-clips have projecting perforated flanges 13, from the two inner ones of which,outside the wooden braces,on each side, two iron brace-rods, 14, extend to near the point ends of the wooden braces,to which and to the tongue they are secured by the curved bolt 15, that passes through the tongue and both sets of braces, and is fastened by the screw-nuts 16.

17 represents the doublctree or evener, which is secured to the tongue by the usual draft-bolt or hammer, 18. The doublctree is provided with clips or eyeletbolts 19 at each end, from which hang the pendent draft-bars 20, that are connected through perforations at their lower ends by the draftrods 21 with the perforated flanges 13 of the aforesaid draftclips 12, that rigidly embrace the axles alongside the twinjournal-clips to which the shovelcarrier frame is attached. Perforations 22 are placed at graduated distances on the pendent draft-bar for the attachment of the singletree at the draft inclination required.

The shovel-carrier frames 8 are each of them provided with four longitudinal angle bars, 23, two of which are hinged above thejournal-clips and two beneath to each shovel-can rier frame by the pivot-bolts 24, that in each case pass through the rear flanges, 25, of the clips and the corresponding anglebars that are each on the same vertical line, so that it will be seen that the angle bars, that are vertically parallel to each other, are hinged by the same pivot-pins and move in unison with each other. The other ends of the angle-bars are alike correspondingly secured by the pivot bolts 26, which thus pivot the rear ends of the angleirons and are secured in the cross-tree-standard bearer 27.

28 represents the slotted yokes that,th rough their curved slots, provide the means for the adjustment of the upper ends of the standards 30, that carry the shovels aforesaid, 10.

It will be seen that by the eccentric presentation I give to these yokes, one of which is vertical and the other horizontal, and by the corresponding conformation of the standards that carry the shovels, I throw the shovels out of lateral line with each other, as is common with a great number of cultivator-s, so that they are free from the danger of choking, which is a frequent occurrence, especially on foul ground with cultivator-shovels that run alongside each other. The standard secured to the horizontal yoke runs at top in a horizontal line, and after reaching back a suitable distance out of lateral line with the other it then curves around downward, conforming to the usual presentation for the right lay of the shovel. The other standard reaches vertically above the cross-tree, also inline with its yoke, and not reaching back, as does the other standard described above. Its positionis, in consequence, in advance of the other.

With both standards, the pivotal bolt 31 passes through both standards and through the' cross-tree bearer, and is secured by the screwnut 32. The lay of theshovels is regulated by the pivotal movement of the standards on their common bolt 31, and they are firmly held to said lay by the set-bolt 33 and its screw-nut 34, that secures their set in the curved slots 29 of the yokes.

The bow-springs 9, that provide a flexible suspension to the shovel-carrier frame, are secured at their fast end by the screws 35, that engage in the vertically projectinglugs 36, that rise from the flange-plates 13. Couplingbars 37 are secured by screw-bolts or rivets 38 to the adjoining upper angle bars of each shovel-bearing frame, and chains 39, the fast ends of which are keyed or otherwise secured within the holes 40 in the coupling-bars, have their loose ends rove through the eyelets or loops 41, that hang pendent from the loose end of the bow-springs, and the hooks 42 at the ends of the chain are made to engage in a link of said chain to keep the automatic flexible suspension of the shovel-carrier frame at the right level.

Perforated studs 43 are rigidly secured to the cross-tree-standard bearers and angle upward and back therefrom, and the handles 44 are secured to said studs by the screw-bolts 45 and their nuts 46.

It will be seen that the shovel-carrier frame is free to swing both vertically and laterally, and responds in either direction to the will of the operator under the least movement of the handles, at the same time that the spring aids' handles, but also they help each other in the regularity of their movements, and are not as readily thrown around by the contact of the shovels with stones, clods, &c., as would be a single shovel-bearer bar with a single pivotal adjustment at one end also, by the eccentric sea-102 position of the yokes and standards that adjustthe lay and the posit-ion of the shovels they carry, the shovels are placed out of lateral line with each other, so that they cannot foul each other.

The fourfold angle-bars of each carrierframe, with their compound vertical and lateral adjustability, enable the operator to direct the shovels or plows to a nicety, and to cultivate closeto and even around the young plants at the first tending without choking or covering the tender plant, and, also, at the last time or times of tending it enables him to bank up the hills around the mature growth, ready for laying by, as it is termed,which, if it be a corn-field, is the last work done therein until the cutting up of the corn.

I have shown and described two iron bracerods besides the wooden braceson each side of 8;

but they may be, and are also intended to be,

attached to riding-cultivators,and their means of attachment are exactly similar to those above described.

It being old and well known to provide for parallel motion of a pair of drag-bars, with the resulting effect of presenting the shovels at right angles to the line of travel, whether the bars are in their normalposition or swinging to the right or left, I do not claim, broadly, the means for carrying the same into effect; but

I claim as my invention 1. In a cultivator, the combination of the upwardly and laterally swinging shovel-bearing frames 8, consisting of four angle-bars, 23, journal-clips 11, loosely embracing the main axle of the cultivator and having rearwardlyprojecting flanges, pivot-bolts 24, connecting the front ends of the angle-bars to said flanges, cross-tree-standard beams 27, pivot-bolts 26, connecting the rear ends of the angle-bars to said cross-trees, the eccentrically-placed slotted yokes 28, and diverse-shaped standards arranged to carry the shovels out of cross-line with each other, substantially as set forth.

2. In a cultivator, the combination of the journal-clips, the compound pivoted frame carried thereby and providing upward adj ustment therefor, said frame having four pivoted angle-bars, the crosstrce-standard bearer to which their rear ends are pivoted, the eccentrically-placed slotted yokes, the screw-bolts 45, adapted in conj unction with the said yokes to set the adjustment of the diverse-shaped standards 30, the arched axle 2, the braces 5, that connect the tongue to the arch of the axle, and the braces 14, that connect said tongue to the lower sections of the axles, substantially as set forth.

3.
