CU LTIVATO R.

SPECIFICATION forming part of Letters Patent No. 449,642, dated March 31, 1891.

Application filed December 18, 1888. Serial No. 293,955. (No model.)

To all whom it may concern.-

Be it known that I, JACOB \V. 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, being designed more particularly as an improvement on the cultivator shown and described and claimed in Patent Nof-JSSQOO, granted to me August 21, 1888.

The invention comprises the details of construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a broken perspective view of my improvement, viewing it from the rear; and Fig. 2, a similar detailed view thereof enlarged.

Inasmuch as my present invention relates only to the mechanism for shifting the cultivator beams and shovels in connection with the movement of the wheel-axles and the mechanism for keeping an even pressure on all the drag-bars, I-will only describe those parts of my cultivator, the same being sufficient to a clear and proper understanding thereof. I

Referring to the drawings, A designates the tongue, and a a the side bars, of the cultivator-frame.

B Bare two short stub-axles suitably mounted in place, and to the inner ends of these stub-axles are connected the outer ends of divergent rods 1) b, the inner ends of which are pivotallysecured to an L-shaped lever or bar b pivoted to the under side of tongue A.

Two depending bars O O are each loosely secured to the forward end of an approximately V-shaped bar 0', secured at its rear end upon one end of a coiled spring-rod O to the other end of which latter part 0 is secured a bar similar to O, (not shown,) said rod O being pivotally mounted at its center to a cross-beam of the frame, as at B. Two parallel arms (I O are pivotally secured at their front ends to bar 0 and at their rear ends they are rigidly connected to. a transverse rod 0*, loosely mounted in the side bars of the carrying-frame. A lever C is rigidl; secured to the rod 0 and is designed to en gage a toothed rack 0, attached to the side bar (I.

The lower ends of bars O O are seen red to the drag-bars O at d, and to these bars O are pivotally secured the outer ends of two bars D D, pivoted to each other at d.

E is a connecting-bar secured at one end to the rear end of the L-shaped lever or bar b and at its other end the same is held by a loop a to the pivotal point of the bars D D.

From the foregoing description it will be seen that the turning of the stub-axles on their'pivotal posts cl (indicated in Fig. 2 will through the agency of the rods 1') 1) effect the turning of the L-shaped lever, and by means of the connecting-bar E' and the bars D D cause the drag-bars to move in the same direction as the wheels of the cultivator. By this means the cultivator-shovels are always kept parallel and caused to move in the same line with the wheels. It will also be seen that by moving the lever 0 forward it will cause the lowering of the forward ends ofthe parallel bars 0 and the V-shaped bar O, eifect- 8o ing the lowering of the drag-bars. If the pressure on one set of drag-bars is too great, the forward ends of bars 0 and C will be raised, causing the lowering of the rear end of said bar 0 and that end of the coiled rod O to which it is connected, and consequently effect the raising of the other end of said rod, thus keeping both sets of drag-bars at same depth and pressure at all times.

I claim as my invention 1. The combination, with the frame and the stub-axles, of the L-shaped lever or bar, the divergent rods Z) Z), the bars D D, the depending bars 0, and the drag-bars O substantially as described.

2. As an improvement in cultivators, the

coiled-spring rod secured at its center to the frame, the V-shaped bars secured at their rear ends to the ends of said rod, the parallel links or arms, the depending bars 0 O, and the d ragbars, substantially as described.

The combination, with the frame, of the coi1-springrod, the transverse rod C", the parallel arms 0", secured thereto, the bars 0 C the dragdvars, the lever, and the rack-bar, sub

stantially as set forth. :0

In testimony whereof I al'lix my signalu re in presence of two witnesses.
