" TOOL HOLDER FOR CULTIVATORS.

Application filed February 24, 1921.

To all whom it may concern: 1

Be it known that I, Cnannns H. /Vitirn, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Tool Holders for Cultivators, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to tillage machines and more particularly to that class having earth stirring devices laterally adjustable to vary the distance apart and vertically adjustable to vary their depth of work.

The object of my invention is to provide a simple and effective means of adjustably securing earth stirring devices to machines of the class stated.

Referring to the drawings in which similar numerals indicate identical parts-- ldigure 1 is a plan view of a cultivator embodying my invention.

Figure 2 is a side elevation of Figure 1.

Figure 3 is an enlarged detail plan view of my device as employed.

Figure 1 is a sectional view on the line fir-4c of Figure 3, and

Figure 5 is an enlarged perspective view of the tool holding clip.

I have shown my device as applied to a riding cultivator to the front frame bar 1 of which are pivotally connected rearwardly extending drag bars 2, 3, 1 and 5, carrying at their rear extremities parallel bars 6 and 7. The bars 6 and 7 are spaced apart one above the other, in parallel relation, and are bolted to castings 8 and 9 secured respectively on the drag bars 2 and 5; the bar 6 is provided with a series of equidistant notches 10 on each side which register with similar notches in the bar 7 and in which standards 11 and wedges 12 are adapted to be held by bifurcated holders 13. The latter are made preferably of sheet metal bent upon itself to form a U, and are provided with slots 14 and 15 in one arm which are in vertical alinement respectively with slots 16 and 17 in the opposite arm.

The holders 13 are employed between the bars 6 and 7 and extend beyond the latter on both sides so that the standards 11 and wedges 12 can be readily inserted in the slots therein. in mounting a standard, to which the desired tool is supposed to be attached, the standard can be placed in the slots 14 Serial No. 447,382.

and 16 before the holder is passed between the bars 6 and'7, or the holder can be put in place between the bars 6 and 7 before the standard is inserted in the slots 1d and 16. After the standard is in place in the slots 14 and 16 and engaged with notches in the bars 6 and 7, on the opposite sides of the latter I employ the wedge 12 in the slots 15 and 17, the wedge engaging with notches in the bars 6 and 7 directly opposite those in which the standard 11 rests, and by driving the wedge firmly in place the parts are held rigidly together; the slot 17 is of a lesser length than the slot 15 to conform to the slant of the wedge .12, and the width of the bars between opposite notches is greater than the space 18 between the slots 14 and 15 and the slots 16 and 17 to provide for standards of varying sizes and to ensure rigidity in the relation of the assembled parts.

It will be readily understood that in providing numerous opposite notches in the bars 6 and 7 the distance between the tools employed can be increased or diminished as may be desired, and it is also evident that by reversing, or turning the holders end for end, the tools may be carried either to the front or rear of the bars 5 and 7.

What I claim is v 1. In a cultivator, the combination of a frame, bars mounted transversely thereon one above the other in parallel relation, a series of notches in both edges of each bar, the notches in one bar registering with the notches in the other bar, each notch in one side of each bar being directly opposite a similar notch in the other side thereof, a tool carrying standard, a holding means for the standard extending between the bars and beyond both sides thereof and adapted to receive the standard on one side of the bars and to hold it in adjacent notches, and means on the opposite side of the bars cooperating with said holding means and with adjacent notches to retain the standard in rigid contact with said bars.

2. In a cultivator, the combination of a frame, tool carrying bars mounted transversely thereon one above the other in parallel relation, a tool standard, a bifurcated holder adapted to be inserted between said bars and to extend beyond both sides thereof, slots in the arms of said holder to receive said standard on one side of said bars,

slots in the arms of the holder on the opposite side of said bars to receive a wedge in contact with said bars to hold the tool 4:. In a cultivator, the combination of a frame, tool carrying bars mounted transversely thereon one above the other in parallel relation, a series'of notches in the sides of each bar, a bifurcated holder extending between the bars and beyond the sides thereof, slots in each end of the arms of the holder extending respectively beyond the sides of the bars a tool standard held in the slots and adjacent notches on one side of said bars, and a wedge. operating in the slots and adjacent notches in the opposite side of the bars to place.
