JACOB \V. KRAUS, OF STERLING, OHIO.

CU LTIVATOR.

SPECIFICATION forming part of Letters Patent No. 372,627, dated November 1, 1887.

Application filed August 2, 1887.

To all zrhom it may concern.-

Be it known that I, J ACOB W. KRAUS, a citizen of the United States of America, residing at Sterling, in the county of \Vayne and State of Ohio, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in cultivators, the same having reference more particularly to that class of riding or walking cultivators wherein suitable means are employed for regulating the direction of the movement of the cu1tivator and for drawing together or moving apart the cultivatorshovels; and the invention consists in the detail construction, combination, and arrangement of the parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my invention. Fig. 2 is a rear view thereof. Fig. 3 is a front elevation. Fig. 4 is a longitudinal sectional view on the line :0 00, Fig. 1. Fig. 5 is an enlarged detail perspective view, and Fig. 6 is a view in perspective, of my invention, showing the cultivator-frame in dotted lines.

Referring to the drawings, A indicates the cultivator-frame, consisting of two longitudinal bars, a a, and two end connecting-bars, a a, and to the center of this frame is connected a forwardly-projecting bar, (L to the forward end of which is secured the rear end of the tongue, of ordinary construction.

13 B are the ordinary carrying-wheels of the cultivator, having each a short axle, Z), which are extended inwardly under the cultivatorframe, said axles being connected with the rear cross-bar ofsaid frame by bent or stepped plates or brackets b b. The connection between the lower horizontal ends of said plates or brackets b and the short axles Z) is effected by means of nutted bolts b, passed through corresponding apertures in said plates or brackets, and thus forming a pivoted connection therefor.

To the underside of the front bar, a, of the frame A is connected the upper portion or vertex ofan approximatelyinverted-V-shapcd metallic bar b the lower outer ends of which Serial No. 215,938. (No model.)

are flanged and provided each with an aperture.

C O are two correspondingly-formed cultivator shovel standards or bars, the forward vertical portions of which are projected up through the apertures in the ends of the V- shaped bar I), and through apertures in the outer forward ends of the sidebars of the frame A, and are there loosely secured by means of nuts screwed on the projecting threaded ends thereof. To the rear ends of the curved portions of these cultivator-shovel standards are secured, by ordinary means, the cultivatorshovels (Z d, of any preferred form of construction.

D D are two similarly-constructed plates or arms secured at their lower rear ends to the center of the short axles b, from which point said plates or arms are bent upward and forward, and are provided at their outer ends, one, D, wit-h three corresponding apertures, and the other, D, with a single aperture, as shown. Through the single aperture in the plate or arm D, and the forward aperture in the plate or arm D are passed the right-angularly bent ends of an approximately inverted- U shaped connecting-bar,D. Through the second or central aperture in the plate or arm D is passed the right-angular portion or end of a cross-bar, D connected at its other lower end to the cultivator-shovel standard 0 at a point about under the forward end of the plate or arm D, as shown.

E is a curved connecting rod or lever connected at its lower end to the cultivator-shovel standard 0 at a point adjoining the cross-bar D, and said rod or lever is at its center bent around a horizontally-disposed pin or rod, d, and is then extended slightly upward a short distance and terminates in a vertical portion or arm, This arm (1 of the lever E is socured to about the center of a lever, F, pivotally secured at its forward end to the front cally-disposed notched arm or bar, f, secured at its lower end to the cultivator-shovel standard G.

F is a curved rod or arm secured at its up- ICO 9, the lower right-angular end of whichis projected through the third or rear aperture of the plate or arm D. The rear end of this lever G is extended some distance beyond the rear bar of the frame A, so as to be within convenient reach of the operator or driver.

From what has been said itwill beseen that by moving the lever G to either side of its central position, according to the direction in which it is sought to perform the cultivating operation, the cultivator shovel standards, together with their shovels and the wheels with their short axles, will, through the agency of the curved arm 9, the connectingbars D, the

curved cross-bars D, and the plates or arms D D, be caused to turn in the desired direction for the purpose above stated. Thus it will be seen that the wheels and the cultivator-shovels and standards can at any time be readily shifted from side to side, as may be desired. My invention also comprises means for drawing together or forcing apart the cultivator-shovels, according to the width of the furrows it is desired to make. This is done by means of the horizontal lever F, the curved rod or lever E, and the rod or arm F. By raising the rear end of the lever F the same will, through the agency of the curved rod or lever E and the rod or arm F, draw the cultivator-shovels toward each other, and the same can be secured at the desired point by cans ing the rear portion of the staple secured to the lever G to enter any one of the notches of the bar or arm f.

This invention is alike applicable to riding and walking cultivators, and when employed asthe former a suitable seat is secured to the rear portion of the frame A.

I claim as my invention- D, the curved cross-bar, and the forwardlyprojecting apertured plates or arms, substantially as shown and described.

2. The herein-described cultivator, comprising the wheels having the short axles, the cultivator-shovel standards, the forwardlyprojecting plates or arms having apertured ends, the U-shaped connecting-bar D, the curved cross-bar D", the curved lever E, fulcrumed at about its center, the lever F, pivotally secured to the frame and having the upper portion of said curved lever connected thereto, the curved arm or rod F, secured to the fulcrum-pin of said curvedlever, the lever G, projecting beyond the rear oft-he frame, and the connect-ing-barg,'secured thereto and to one of said apertured plates or arms, substantially as shown and described.

3. The combinatiomwith the frame and the wheels having short axles provided with bent plates or arms, of the lever G, the inclined rod or arm 9, secured thereto, and the connecting-bars D D secured to said plates or arms and to the cultivator-shovel standards, substantially as shownand described.

4.. The combination, with the frame, the carrying-wheels, and the cultivator -shovel standards, of thecurved lever E, secured at one end to one ofsaid standards, the curved arm or rod F, secured to the other one of said standards and to the fulcrum-pin of. said lever, the lever F, pivoted to said frame, and the notched bar f, all constructed and arranged substantially as shown and described.

5. The combination, with the cultivatorshovel standards, of the curved lever E, the rod or arm F, and the lever F, substantially as shown, and for the purpose stated.

In testimony whereot'I affix my signature in presence of two witnesses.

- JACOB W. KRAUS.
