CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 470,030, dated March 1, 1892. Application filed February 14,1891- Serial No. 381,462. tNoniodel.)

1'0 all whom it may concern:

Be it known that we, BENJAMIN F. YOUNG,

JOHN L. VOGEL, and PRESTON S. VOGEL, citizens of the United States, and residents in Smithsburg, in the county of \Vashington, in the State of Maryland, have invented a new and useful Cultivator, of which the following is a correct-description.

The invention relates generally to the class of wheel-cultivatorsthat is, those which are supported and have locomotion upon groundwheels; and it relates particularly to those wheel-cultivators in which the Wheels are made adjustable up or down in relation to the frame or body of the cultivator, so as to vary the depth of the engagement of the teeth with the soil, or, if desired, to wholly disengage them therefrom.

The object of the invention is to provide a construction in which the adjustable shaft upon which the front wheel is carried shall in the forward movement of the cultivator clear a track or way for such wheel, in which the axletree shall rest pivotally in independent pivotal arms which are journaled in the frame of the cultivator, so that the wheels may be adjusted with the least possible degree of friction, and in which the operatinglevers are so attached and so connected with the axle-tree that the power exerted in .adjusting the wheels is applied to the axle-tree with exactly equal force at the two extre1nities thereof.

With this and other incidental objects in view the invention consists in certain novel parts and in certain novel combinations of parts, as will first be particularly described, and then distinctly indicated in the concluding paragraphs of this specification.

In the accompanying drawings, which constitute a part of this specification, Figure 1 represents a perspective plan View of the cultivator, a portion of the frame being broken out to show the connection of one of thejournaled bearing-arms. Fig. 2 is a detail horizontal section showing the relation of the front or guide wheel to its clearing-shaft. Fig. 3 is a detail showing a front view of the transverse beam which bears the crank-shaft and its immediate connections.

The body or frame A of the cultivator A is composed of the side beams a a and the cross-beam a these parts being provided with fixed shovels or teeth a a a in an ordinary manner. At the intersection of the beams a a a vertical opening is provided for the reception of the adjustable clearing-shaft b, which carries the front bearing-wheel E. At its upper extremity the shaft is provided with jaws b 12 within which is pivoted a lever c. Thefront extremity of the lever has a loose connecting-rod c, by which it is made fast to a staple or other fixed part of the frame, and its rear portion extends alongside a rack-bar d, which is rigidly secured to such frame. At its lower extremity the vertical shaft 6 receives the central inclosing loop 6 of parallel horizontal arms 6 e, which at their rear extremity receive the journal or pivot pin 6 of the bearing-wheel E, the relation of the parts being such that the periphery of the wheel is but slightly below the plane of the lower extremity of the shaft upon which it is carried.

Near the rear extremity of the frame each of the beams a a is provided upon its-vertical inner surface with a bearing-arm f, the horizontal journal or shoulder part f of which is received loosely within the body of the beam, while its fore-arm part f is bent outwardly therefrom ata right angle and at its' free extremity is provided with an opening f for the journal g of the axle-tree G. Neareach extremity the axle-tree G is bent to form a loop or cranlcar'm g, which receives the rear extremity of a connecting-bar I, while be tween the loop and the extremity of the axletree or wheel-shaft is received one of the rear wheels F.

Along the upper surface of the transverse beam a is extended a crank-shaft H, which is secured in journal-plates h h and which beyond such journal-plates is bent into or is provided with a crank-arm h h, the hori-- zontal extremity h of which receives the front 9 5 extremity of the connecting-bar I, already re ferred to. An operating-lever H is rigidly attached to the crank-shaft H and is provided with a self-acting latch h. A rack-bar J is connected at its rear extremity to the cross- IOQ.

beam a and at its front to a cross-bar a or other suitable support.

A suitable operators seat K is supported upon a standard 76, which rises from the crossbeam d As will be seen, the relation of the operators seat to the two adj usting-levers is such that control of both front and rear wheels is easily effected.

At the front a suitable connecting or attaching loop Z is provided for engagement of the draft apparatus and at the rear supplemental arms on may be provided, so that the attendant may operate the cultivator from the ground instead of from the seat whenever desired.

By reason of the location of the adjustable clearing and carrying shaft in advance of its wheel it operates either to penetrate and cleave and divide or to push to the right or to the left any clods of earth or sod which may obstruct its forward movement and to thus provide an unobstructed way for the progress of the wheel in substantially the same horizontal plane, whereas if the wheel constituted simply a downward prolongation of its shaft its tendency on encountering such obstacles would be to rise upon and pass over the same and thus to lift the front portion of the cultivator and disengage the teeth thereof from the soil. The described construction is therefore specially advantageous in cultivating new ground, where many clumps of sod lie unbroken or but partially broken upon the surface.

The provision of the elbowed arm or axletree hearings, in connection with the twolooped crank-shaft and the connecting-bars, insures an equable application of power to the extremities of the axle'tree and the necessary partial rotation thereof with the least possible resultant friction.

The invention having been thus described, what is claimed is- 1. In a cultivator, the coincident elbowed arms f f, journaled in the body of the frame, and the two-looped axle-tree G, journaled in bearings formed in the outer extremity of such elbowed arms and carrying the wheels F F between the inner extremity of the elbowed arms and the outer face of the loop of the axle-tree, in combination substantially as set forth.

2. In a cultivator, the coincident arms ff, journaled in the body of the frame, and the axle-tree G, having the bent loops g g, carrying the wheels F F and journaled in the coincident journaled arms ff, combined substantially as described.

In a cultivator, a crank-shaft journaled transversely upon a cross-beam of the frame, an axle tree carrying parallel adjusting ground-wheels and bent to form crank-arms, and parallel bars connecting the arms of the crank-shaft and the arms of the axle-tree, in combination substantially as specified.

4. In a cultivator, an axle-tree which is provided with looped crank-arms, which for operation receive a connecting-bar, as I, which carries parallel adjusting-wheels and which is journaled in bearingarms, which in turn are journaled in the frame of the cultivator.
