CULTIVATOR I-IOPPLE.

Application filed November 8, 1913.

To all whom it may concern:

Be it known that I, J OSEF D. HILL, a citizen of the United States, residing at Arlington, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Cultivator-Hopples, of which the following is a specification.

My invention relates to a new and useful cultivator hopple and its object is to provide a cultivator hopple that Will requ1re very little manual exertion to ad ust the cultivator beams between their limiting positions. D

A further object is to provide a cult vator hopple that will be strong, durable, simple and efiicient and comparatively easy to construct, and also one the various parts of which will not be likely to get out of working order.

With these and various other ob ects n view, my invention has relation to certain novel features of the construction, an example of which is described in the followlng specification and illustrated in the accompanying drawing, wherein:

Figure 1 is a rear view showing my cultivator hopple operatively mounted upon a pair of cultivator beams. Fig. 2 1s a v ew of the same in side elevation. Fig. 3 1s a vertical detailed sectional view, taken upon the line 'w w of Fig. 1. Fig. 4: is a detailed sectional horizontal view, the section being taken upon the line wm of Fig. 2.

Referring now more particularly to the drawing, wherein like reference characters designate similar parts in all the figures, the numeral 1 denotes a pair of ordinary cultivator beams, mounted in the usual substantially parallel spaced relation. Upon the beams 1, there are respectively mounted two oppositely disposed collars 2 formed with integral lugs 3 projecting toward each other. The lugs 3 are each apertured to receive a pin 4 depending from a bifurcated bracket 5, one of which is seated upon each lug. The brackets 5 respectively receive between their furcations the lower extremities of two hopple members 6, which members extend upwardly at a slight inclination toward each other, and at their upper extremities are curved to bring one of said members in front of the other, pivotal connection being established between the two as indicated at 8. Above the pivot 8, the members 6 are respectively formed with integral upstanding brackets 9 and 10, the

former being disposed to the rear of the latter, and terminating at a lesser height. The brackets 9 and 10 respectively terminate at their upper extremities in arcuate racks 11 and 12, the latter rack having the lesser radius. At the center of curvature of the rack 12, a short rock shaft 13 is passed through the bracket 10, said shaft being formed with square end portions projecting at each side of the bracket. A pinion l4 shrouded asindicate at 15 is mounted upon the squared portion of the shaft 13 to the rear of the bracket 10, said pinion having engagement with the rack 11, in the rear of which rack the shroud 15 projects. In front of the bracket 10, there is mounted upon the squared portion of the shaft 18 the lower extremity of a normally vertical lever 16, with which is correlated the usual manually controlled spring-pressed lever 17 adapted to engage with rack 12 to hold the lever in various positions of angular displacement. Just below the pivot 8, a lug 18 is mounted upon the front hopple member 6, with which is loosely connected the rear extremity of a rigid link 19, the forward extremity of which link is adapted to be loosely connected in any suitable manner to the tongue or any other fixed part of a cultivater. The bar 19 maintains the hopple in avertical position, at the same time permitting it to rock or sway with the movement of the cultivator.

From the above description, it is apparent that by actuating the lever 16, the beams of a cultivator may be adjusted to or from each other to any desired extent, it being possible for the operator to accomplish this adjustment during the travel of a cultivator. It will also be readily seen that the operating mechanism of my hopple affords a leverage such as will permit the beams to be adjusted as desired with very little manual exertion.

My invention is presented as including all such modifications and changes as properly comes within the scope of the following claim:

What I claim is:

A cultivator hopple comprising a pair of pivotally connected diverging hopple bars, respectively connected at their lower ends to the beams of a cultivator, brackets respectively carried by said bars and extending adjacently upward above their pivotal points, arcuate racks respectively surmounted upon said brackets, a shaft rotatably mounted in one of said brackets, a pinion fast upon said shaft engaging the rack surname to this specification in the presence of mounting thefother braicket, a leireg fast two subscribing Witnesses. u on said sha t and a 0 carrie the le er engaging the rack s urmounting the JOSEF' HILL 5 bracket supporting the shaft carrying the Witnesses:
