SPECIFICATION forming part of Letters Patent No. 584,022, dated June 8, 1897.

Application filed October 29, 1896. Serial No. 610,495. (No model.) I

To (tZZ whom it ntay concern.-

Be it known that I, MARQUIS J. TODD, of Buffalo, in the county of Erie and State of New York,have invented certain new and useful Improvements in Cultivators; and I dohereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in cultivators, having reference particularly to that class employing laterally-adj ustable side-bars to which the shovel-standard are secured.

The principal object of the invention is to provide a cultivator of this class which shall be firm and rigid at all points, avoiding all wabbling or rocking of any of its parts.

A further object is to so connect the gagewheel standard that the wheel can be swung back under the frame for ease in transportalion, all of the shovels being raised above the ground.

A further object is to prevent any wabblin g of the central frame-bar at the points of connection of the adjusters to cause the bars of said adjusters to move in unison and to avoid the use of nutted bolts in connecting said bars to the frame.

A further object is to enable the shovels to be readily adjustable on their standards and to allow some of the latter to be adjusted to control the pitch of their shovels, and also to provide improved forms of standards and connect-ions therefor to the frame.

' A further object is to provide improved means for permitting lateral adjustment of the handles.

A further object is to provide a simple and highly-efficient clevis.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective. Fig. 2 is aside elevation showing the wheel thrown back under the frame. Fig. 2 is a sectional detail view on line 2 2, Fig. 2. Fig. 3 is a plan view. Fig. -l is a view of one of the shovels and its standard. Fig. 5 is a section thereof on line 5 5.

Fig. 12 is a rear view of one of the shovels with parts broken away. Fig. 13 is a horizontal sectional view on line 13 13, Fig. 9. Fig. 1a is a longitudinal sectional view of the adjuster-lever. Fig. 15 is a view in pei spective of the adjuster-head. Fig. 10 is a view of the wedging-plate. Fig. 17 is a slight modification thereof in section. Figs. 18 and 19 are details. Fig. 20 is an enlarged sectional view on line a: on, Fig. 3.

Referring to the drawings, A designates the frame as an entirety, a the central bar, and a a the curved or bowed adjust-able side-bars, all of which are preferably formed from I-bars. To the forward end of each bar co is secured a hinging-hub (1?, having lateral plates a between which fits the end of the bar. Screws a hold said end sandwiched between said plates. These hubs have Vertical bolt-holes and at their ends a are tapered. Upper and lower cap-plates o are provided on their inner faces with lugs a to engage the side edges of bar a, and also with the tapered recesses aiwherein lit the tapered ends of the hub. Through these hubs and coincident holes in the cap-plates are upwardly passed nutted bolts a. By tightening the nuts of these bolts the ends of the hubs are firmly held in the recesses of the cap-plates, and the latter are secured to the frame-bar.

To the rear end of the frame-bar a and also to the side-bars a, at opposite points, are secured the standards Z) of the ordinary cultivator-shovels B. Each of these stand ards is composed of two separable bars Z), held at their upper ends by bolts Z2 to the opposite sides of the webs of the frame-bars. The shovels B are held fast to their standards by nut-ted bolts b and clips 6 having inner grooved faces If, in the grooves of which are serrations b, engaging corresponding serrations of the bars I). By means of these clips the bars Z2 are drawn toward each other ICO near their lower ends, thus giving a slight outward curvature to the central portions of said bars, adding to the strength thereof. The shovels can be readily adjusted on their standards. The forward end of the framebar 66 is bent or curved downwardly, as at 19 and in it is formed a series of holes b through any one of which is designed to project a spring-pressed pin b of a clevis O. This clevis has a looped end 1) in the parallel sides Z1 of which are formed coincident openings I) I). In the latter is a coil-spring O surrounding the shank I) of the pin, the end of the latter being extended and provided with an eye I), by which the pin can be re tracted for the purpose of adjusting or removing the elevis.

D designates the handles, the lower for ward convergent ends of which are adjustably held by a nutted bolt d, passed upward through a slot at in a slightly-curved channel-- bar d This bar is rigidly secured to bar a, preferably by a yoke (1 and it is extended outwardly so as to project over and bear upon the bars a. By this means the three framebars are held fixed relatively to each other, and wabblin g of the bars is prevented. Near their upper ends the handles are supported by links (1*, held. at their lower ends to the bar a by abolt (1. The handles being thus secured can be readily adjusted by moving the bolt d in the slot d of bar (1 the head of said bolt fitting against the under side of the latter. This adjustment enables the handles to be thrown toward one side while the shovels are working close up to growing vines.

E E are the shovels at the rear ends of bars .justed to any desired position by moving them on their standards 6 or by adjusting the latter in their clips 6 or by adjusting said clips. The shovels are held to these standards a by two nutted bolts 6 and clips 6 similar to those before described. The adjustable standard-clips e consist each of a tapered body 6 having an upper threaded end 0 and its lower end is provided with opposite slots 6 e to accommodate the divergent ends of the standard-bars, the slots e being set closer together than the slot 6. These tapered bodies fit in hollow hubs a from which extend lateral arms 0 which are bound to opposite'sides of the bars a by nutted bolts c The lower ends of these hubs are slightly curved to accommodate the curvature of the standard, the edges of which are caused to bear thereagainst by nuts 6 on the threaded ends 6 By loosening these clips they can be turned'in the hubs and held at any point, and when so loosened the standards can in turn be adjusted in said clips to throw the points of the shovels at any desired pitch. From upper and lower horizontal flanges e of these hubs project short hooks e.

F F are the adjusters, by which the rear free ends of the side-bars a can be moved away from or drawn toward the central bar.

Upper and lower bars f of these adjusters engage at their outer ends the hooks e, and at their inner ends the bars of the two adjusters overlap and engage upper and lower hooks of a headf adjustable longitudinally on bar a, said hooks fitting in holes in said bars. In this way the use of nutted bolts for securing the adj Lister-bars is avoided. The head consists of a skeleton-like frame having a central longitudinal opening to accommodate bar a, and with it is formed a curved rack-barf. with which engages a spring-pressed sliding pawl f mounted within aleverf composed of two parallel bars f. At its lower end this lever is pivoted by a nutted bolt f passed through a transverse hole of the head, the bars f fitting against the sides of said head, one of them being passed inside of an upper slightly-bulged bar f. A hand-lever f; mounted on the lever f is connected to the pawl f by a rod or wire f. From one side of this pawl extends a plate f formed with tapered or wedge-like surfaces f which serve to wedge or bind the adj Listing-head against the central frame-bar. This may be accomplished byhaving said surface engage raised surfaces f on line with the flanged edges or the bar a, (see Fig. 14,) or said wedged sun faces may be formed on the inner faces of the plate extensions f as atf, Fig. 17, so as to directly bear against the side edges of sani bar. In this way when the pawl is in engagement with the rack-bar the head is firmly held. and when said pawl is disengaged the head can be freely moved on the bar. The fnicrum of the lever f consists of two links f which at their lower rear ends are pivotally mounted on bolt (1.

G is the depth-gage wheel, which is so mounted that it also serves as a transportingwheel for holding the cultivator-shovels elevated. It is mounted in the lower end of a lever 9, which is shown as composed of two parallel bars 9, fuloru med on a nutted bolt rf. passed through bar a at a point in rear of the front ends of the side-bars. The bars g, at their upper ends, are recessed at g to receive lateral arms g of a spring-pressed sliding paw t g mounted between the bars 9 composing a lever 9 which is also f ulcrumed at its lower end on the bolt The arms g are movable in opposite longitudinal slots g in the bars 9 This pawl is designed to engage a curved rack-bar g havinga box Q13 rigidly secured on bar a. From the under side of this box projects a lip g An ordinary hand-lever g? mounted on lever g, is connected by a rod or wire 9 to pawl 9 By operating this handlever the pawl can be drawn out of engagement with the rack-bar to permit of the adjustment of the wheel-lever, but in order to free the lateral arms 9 from said wheel-lever the operator grasps the rod or wire g and f u rther retracts the pawls. The desired ad j ustment of the wheel and its lever is effected by the operating-lever g \Vhen the cultivator is to be transported, the pawl is further moved tofree the end of said wheel-lever, and the frame being slightly raised at its forward end the wheel will move thereunder. turning on its fulcrum and engaging the lip g, will hold. the shovels elevated above the ground, as shown in Fig. 2. To return the wheel to its normal position, it is only neces sary to again raise the end of the frame, permitting the wheel to move forward, and the slotted end of the lever is reeugaged bythe lateral arms of the pawl.
