SPECIFICATION forming part of Reissued Letters Patent No. 1 1,708, dated January 10, 1899.

Original No. 598,461, dated February 1, 1898.

, To all whom it may concern.-

' A cross-bar 4 is secured to these extensions:

claimed.

Be it known that I, HIRAM O. YOUNG, a citizen of the United States, residing at Goose- Creek, in the county of J efierson and State of Kentucky, have invented new and useful Improvementsin Wheel-Cultivators, of which the following is a specification.-

This invention relates to wheeled cultivators, and has for its object'to improve that class of two-horse cultivators in which pro vision is made for shifting the line of draft for either plow by simplymoving the plowhandle either tothe right or left, thereby causing the line of draft to always coincide with the line of motion, thus making the plow easy to hold and also keeping the shovels in the same position .at right angles to. the line of motion without regard to the distance between the two parallel plows, which are independently adjustable toward and from each other to varythe line ofdraft for either plow or both plows, as may be required.

The invention consists infeatures of construetion and novel combinations of partsin a cultivator, as hereinafter described and In the annexed drawings, illustrating the invention, Figure 1 is a perspective of a portion of one side of a two-horse cultivator embodying my improvements. Fig 2 is a. front elevation of the same, showing the tongue in cross-section.

Referring to the drawings, the numeral 1 designates an arched axle, and 2 is a tongue or pole the rear portion of which is bifurcated and secured to the upperhorizontal part of the axle-arch. As shown, the bifurcation of the tong'ue2 is extended rearward beyond the point ofattachment to the axle-arch, so as to provide two parallel and rearwardly-projecting horizontal extensions 3 of suitable length.

or bars 3 near their rear ends and isextended laterally beyond the same. At ornear each end of the cross-bar 4 there is a vertical guide 5, in line with a vertical guide 6, supported on a cross-bar 7, that is secured to the tongue 2 at'points in front of and near to the axlearch. The ends of the front cross-bar 7 project laterally to a somewhat farther extent than the laterally-projecting ends of the rear cross-bar 4 and aiford attachment for latereye 16, in

From the under portion of the boxing-13 there project two lateral arms 15, one on each side,- and each of these arms is provided with an which is engaged the lower hooked end of one of the suspension-rods 8, by which the forward end of'the plow-beam is supported.

In. the rear vertical ivertical guide Get each side of the cultivatorframe there is received and supported a lon-' gitudinally-arranged arms of which are connected with a' plowbeam at front and rear, so that by lifting the arched axle and is pref-' provided with a boxing 18, in

bail 17, the dependinghandle 18 of either plow and moving it either to the right or left a corresponding shifting of the line of draft will be instantly accomplished without affecting or changing the proper position of the shovels 19 at right angles to the line of motion. Thus the line of draft will always coincide motion for the shovels, so that it is made easy forthe operator to guide the plows and dodge the crooked hi1ls,.as in cultivating corn or other plants.

The forward depending end of the bail 17 is attached to astud 20 on the front of the boxing 13. at the forward end of the plow beam, and the rear. depending 'end of said bail is formed with an eye 21, that rides on a with the line of rod or arm 22, projecting rearward from the plow-beam adjacent to the plow-handle.

It will be observed that the uides 5 and 6 projeotvertically a suflicient distance to allow for all necessary vertical movement of the plow-beam and attached bail, while the suspension-rods 8 not only afiford a strong and reliable support for the forward end of the IUD .. 55 7 at each side of the vertical guides 6, that are provided near each end of the said front cross-bar.

beam, but also serve to limit any tendency to forward movement in shifting the line of Y draft.

The purpose of the bail 1 7 is to shift the line of draft and cause both ends of the plowbeam to move simultaneously and in substantial parallelism whenever the plow-ham shovel-plows such as are in common use,'the

plow-beams being independent, and the improved'machine can be easily operated so as upper ends of the hangers being to always carry the shovels in the required direction for effective and economical work.

It has heretofore been proposed to connect the forward ends of plow-beams to the lower ends of'hangers which at theirnpper ends are provided with concaved or grooved rollers to travel upon the horizontal portion of an arched axle or upon a cross-rod attached to a part of the cultivator-framework, the

loosely connected with hinged levers for the purpose of maintaining the plow-beams substantially parallel. In such prior construction the upper ends of the hangers slide on the arched axle or cross-rod. transverse to the line of draft, and it has been found that this is ob jectionable in that the leverage on the hangers is so great that it causes them to bind, sometimes preventsthe proper adjustment of the plows, and often renders it dilficult, if not impossible, toadjnst the plow-beams latorally. This objection is entirely avoided by pivotally suspending the suspension-rods so that they can freely swing on fixed pivotal points, as hereinbefore described.

What I claim as'my invention is-- 1. In a-cultivator, the combination with the .independentplow-be'ams, and a frame from which the forward end of each plow-beam is suspended, of vertical guides on said frame,

sand longitndinally arranged bails mounted in said guides and each connected with a plowwhereby a movementplow to the right or beam at front and rear, of the handle of either left will shift the line of draft and maintain the position of the shovels at right angles to the line of motion, substantially as described.

2. In acultivator, the combination of the arched axle, a frame mounted on the axlearch and comprising front and rear cross-bars having vertical guides at or near their ends, independent plow-beams having theirforward ends extended beneath the axle-arms and each provided with a roller to run along the front of an axle-arm, suspension-rods connecting the forward ends of the plow-beams with the said front cross-bar of the frame, and longitudinally-arranged bails mounted in the vertical guides on said frame and each connected with a plow-beam at front and rear, whereby a movement of the handle of either plow to the right or leftwill shift the line of draft and maintain the position of the shovels at right anglQ to the line described.

3. In a cultivator, pendent plow by the axle,

the combination of indebeams, an axle, a frame carried swinging suspension-rods pivotally connected at their lower end portions with the forward ends of said plow-beams, and means whereby a movement ofthe handle of either plow to the right or left will shift the line of draft for that plow, independent of the other, substantially as described.

4. In a cultivator, the combination with in dependent plow-beams, an axle, and a frame carried by said axle, of swinging suspensionrods having their upper ends pivotally attached to said'frame-and their lower ends piv otally connected with the forward ends of the plow-beams, whereby a movement of the bandle of either plow to the right or left will shift the line of draft for that plow, independent of the other, substantially as described.

5. In a cultivator, the combination of independent plow-beams, an axle, a frame carried by said axle, swinging suspension-rods pivotally supported at their upper ends' and havin g their lower ends pivotally connected with the forward ends of the plow-beams, and longitudinally-arranged bails, each flexibly or loosely engaged with parts of a plow-beam and suspended from said frame to swing thereon, whereby a movement of the handle of either plow to the right or left will shift the line of draft and maintain the position of the shovels at right angles to the line of motion, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
