SPESIFIGATION forming part of Letters Patent No. 289,093, dated November 27, 1888.

7 Application filed August- 9, 1883. (No model.)

To ctZZ whom it may concewz:

Be it known that I, REUBEN D. HALL, a citizen of the United States, and a resident of New Hampton, in the county of Harrison and State of Missouri, have invented certain new and useful Improvements in Cultivators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of my improved cultivator. Fig. 2 is a bottom view of the same, and Fig. 3 is a side elevation.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to cultivators; and it consists in the improved construction and combination of parts of a cultivator of that class in which the depth of draft and also the distance between the shovelbeams may be regulated, as will be hereinafter more fully described and claimed.

In the accompanying two sheets of drawings, A represents the arch of the cultivator, and B a frame, to the sides of which the ends of the arch are bolted. This frame is bent in the manner shown in the drawings, its central part being supported upon the tongue 0, the end of which is bolted to the center of the arch A.

D D represent arms, which are hung beneath the ends of the double-tree E, the lower end of each arm beingconnected to the corner of the frame B by means of a pivoted rod, F. The arms D D are provided with a series of apertures, D, in order that the single-trees H may be connected to the said arms at several points, by which arrangement the draft may be increased or lessened, as desired.

I indicates segmental racks, which are secured upon the sides of the frame 13, as shown in the drawings.

J represents levers, which are pivoted one upon each of the sides of the frame B, the lower end of each lever being bent or curved and provided with a stud-axle, J, upon which the wheels of the cultivator are journaled. The upper part of the lever is provided with a spring catch or detent, J, which is adapted to engage with the segmental rack I, so as to lock the lever in its raised position.

K K represent the shovel-beams, which are hinged at one end to the ends of the frame B in such a manner as to adapt them to move in a horizontal plane, the forward curved ends of the said beams being bolted to the curved inner ends of the handles L. These handles L are supported in yokes M, bolted to the under side of the arch A.

N indicates the removable shovelstandards, the upper ends of which pass through apertures in the shovel-beam, and are held in place by means of nuts N, so that when a larger or smaller shovel than the one being used is required the shovel-standard can be removed from the beam by unscrewing the nut N and standard bearing a shovel of the desired size put in its place.

The manner of operating my improved cultivator is as follows: In order to increase or lessen the draft, the single-trees H may be secured, by means of the series of holes D, to any part of the arms D I), by which arrangement the desired object will be attained. By raising the levers J J the shovels may be raised some distance above the ground to enable them to pass over any obstruction, while by depressing the said levers to the lowest possiblepoint the weight of the cultivator can be thrown upon the shovels to put them in hard ground. By means of the handles L the distance between the shovel-beams K K can be regulated at the will of the operator. The for ward curved ends of the shovel-beams are supported not only by the forward ends of the handles L, to which they are bolted, but also by the frame 13, upon which the forward ends of the shovel-beams bear. By constructing the handles L to work freely in the yokes M, instead of pivoting them therein, I enable the said handles to work with much greater freedom and prevent them from binding, which they would do if pivoted in the said yokes.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of my improved cultivator will readily be understood without requiring further explanation. It will be seen that by constructing my improved cultivator IOC in the manner described I am enabled to in- L, having their forward curved ends pivoted to crease or lessen the draft at will, to regulate the forward curved ends of the shovel-beams the depth of the furrow cut by the shovel- K K, and adapted to work freely in the yokes 15 blades, and also to adjust the distance between M M, as set forth. 5 the shovel-beams, as may be desired. In testimony that Iclaim the foregoing as my Having thus described my invention, I claim own I have hereunto affixed my signature in and desire to secure by Letters Patent of the presence of two witnesses.
