SPECIFCATIQN forming part of Letters Patent No. 411,733, dated September 24, 1889.

Application iiled June 15, 1889.

To all wiz/0171, it may concern.-

Be it known that I, HALLECK OLE SANDERS, a citizen of the United States, and a resident of Madison, in the county of Dane and State otVVisconsin, have inventedV certain new and useful Improvements in VVheel-Cultivators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has relation to wheel-cultivators; and it consists in the construction and novel combination of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings forming part of this specication, and in which like letters of reference indicate corresponding parts, Figure 1 is a view in perspective of a wheel-cultivator, the machine being viewed from in front of the axle. Fig. 2 is a view in perspective of a wheel-cultivator, the same being viewed from in rear of the axle. Fig. 3 is a vertical longitudinal sectional view on the line of the pole, showing one-half of the operating mechanism of the machine. Fig. 4 is a plan view of onehalf of the machine, taken on the line of the draft-pole, the two halves being constructed in exactly reverse positions.

Referring by letter to the drawings, A des= ignates the axle of the machine, which is arched upwardly between the journals B B, which enter the boxes in the hubs C C of the supporting-wheels, and is connected at its longitudinal middle line to the rear end of the pole or tongue D of the cultivator. The upper face of the axle is provided with notches E on opposite sides of the tongue D, in either one of which may be locked the rear end of the appropriate lever F or F', as

j the case may be, said levers F F being fulcrumed on opposite sides of the tongue D in bifurcated bearing-arms projecting laterally from the tongue of the machine a short distance in front of the arched axle. Outwardlybent and downwardly and rearwardly inclined bearing-arms G Gr are securely bolted through their front ends H H to the side faces of the Serial No. 314,394. (No model.)

pole or tongue D, and their rear ends K K are let into recesses in the axle and terminate in forwardly-projecting downwardly-im clined short :arms M, having eyes N. In these eyes are secured the rear ends of the chains O, the front ends of said chains O being secured in the lower ones of a set of holes in the equalizer-bars S, which are hinged to the out-er ends of the doubletree T, secured upon the tongue D. To the draft-equalizer bars are secured the singletrees U, which may be shifted either up or down, as may be necessary, from one hole to another in the equalizer.- bar.

On a transverse rod V, fixed through the tongue D and through the inclined bearingarms Gr G, are loosely mounted universal sleeve-joints WV W, the rearwardly-extending vertical rings X X of which engage the bi furcated forward ends Y of the levers F F. The front ends of the cultivatonbeams Z Z are xed on vertical rods l-1,which are hinged in the sleeves .3 of the universal sleevejoint. Transverse pins 5, pass through aligned perforations d in the rods 1 and wearingdisks 4. to hold all in place. It will be seen that by means of the levers F F and the universal sleeve-joints W W the cultivator-beams are capable of both lateral and vertical adjustment.

The rear ends of the cultivator-beams are provided with vertically-disposed segmental arcs 7,which are engaged by spring-controlled detents 8, fulcrumed to the bifurcated levers 9, the said levers 9 being fulcruined to the cultivator-beams Z Z. The front ends of said levers 9 are curved downwardly at 10, and between these downwardlyurved ends 10 are loosely secured the slotted arms or links 1I. The links ll are bolted to and form an integral part of the angularly-bent arms l2, to which the cultivator-teeth 13 are fastened. The angularly-bent arms 12 are fulcrumed to the rear ends of the cultivatorbeams Z Z, so that by operating the levers 9 either up or down on their fulcrums the cultivators may be either raised or lowered so as to enter the ground at the proper or required angles. j

Lifting-levers l5 16 are fulcrumed at their front ends to angle-irons 17, secured to the pole or draft-beam, and are providedalso with laterally-projecting metallic arms 18, which are adapted to engagethe teeth of vertical rack-standards 20 and 21, rising from the frame of the machine. These laterallyprojecting arms 18 are connected by chains 22, which run over pulleys 24 at the upper ends of the rack-standards upon the transverse connecting-rod 26 tothe eultivatorbeams near' the rear ends of the latter, so that either of the cultivator-beams with their teeth may be raised entirely out of operation Whenever desired by the driver of the cultivator. 4

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-v- 1. In a Wheel-oultivator, the combination, with the cultivator-beam, the arched axle, the inclined guard-bearing, and the trans# verse shifting-rod, of the universal sleeve on said shifting-rod, the bifurcated shifting-lever engaging the universal sleeve and engaging also the notched axle of the cultivatorbeam connected to the universal sleeve, the arc-rack at the rear end of the .cultivatorbeam, the lever pivoted to the cultivatorbeam and provided with the front bent end and the d'etent at its rear end, the hinged cultivator-shank connected tothe pivoted lever byy a `slotted link-arm, and transverse pins, substantially as specied.

2. In a Wheel-cultivator, the combination,

with the main frame, ofthe laterally-movable universal sleeve and its shifting-lever, the cultivator-beam connected thereto by a vertical rod having a Wear-plate at its upper end, the segmental rack secured to the rear end of the cultivator-beam, the pivoted cultivatorshank on the rear of the cultivator-beam, the pivoted lever having the bifurcated down- Wardly-bentfront end and the spring-detent l' at its rear end, the slotted link connecting the hinged lever to the pivoted cultivatorbeam, the vertical racks connected at their upper ends and provided with pulleys, the

lifting-levers provided with the laterally-pro
