IMPROVEMENT IN GORN-OULTIVATOB.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALEXANDER CAMPBELL, of Oxford, in the county of Benton, and State of Indiana, have invented a new and improved Corn-Cultivator; and I do hereby declare that th following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being bad to .the accompanying drawings, forming part of this specification.

i This invention relates to a new and improved corn-cultivator; and it consists in a new and improved manner of attaching the shovel-standards to the frame of the machine, as hereinafter fully shown and described, whereby any desired pitch may be given said standards as required.

The invention also consistsin a novel manner of securing the shares to the standards, whereby said shares may be reversed, that is to say, changed from one standard to another, and also adjusted in a straight position so as to face the line of draught, or be placed" there or less obliquely therewith, either to the right or left, as maybe desired. i

In the accompanying sheet of drawings- Figure 1 is a side sectional view of my invention. v

Figures 2 and 3, horizontal sections of the same, taken through the rear standards, as indicated by the line :c :r, fig. 1, v a

Similar letters of reference indicate corresponding part-s.-

A represents the frame of the device, which is of 'v -f'ortn, orwider at the rear than atthe front; 13 is the draught-pole, and C the handles. I

The side pieces a a of the frame A are mortised to receive the upper ends of standards D, the. mortiscs b b'eing'su fi'iciently long to admit of-the standards D working therein. I

The standards are secured in the mortises atany desired pitch or angle by means of wcdgcsor keys 0, and stay-rods d, the front ends of which are attached to a rod, e, fitted in an eyc,f, secured to the under side of the draught-pole, the rod e being perforated at equal distances apart, through any of which a pin, 9, passes.

By this arrangement, any desired degree of inclination or pitch may be given the shovels or shares E, as will be fully understood by referring to fig. 1.

The lower front parts of the standards D are chamfered oil so as to form a surf'acc at right angles with the draught-pole or line of draught, and admit of all the shovels being reversed. any share being attached to any standard, the former being secured to the latter, each by a bolt, a

The front shares are generally pointed, but the rear ones are nearly square, and theyliave oblique-shaped blocks 71; attached to their rear sides, as shown clearly in figs. 2 and 3.

.These blocks give an oblique position to the rear shares, and by reversing their position that is to say, shifting them from one rear standard to the other, the earth may be thrown towards or from the plan'ts, as required, and in ploughing or operating in old corn-ground, the shovels'or shares, when set obliquely, work to better advantage in throwing out the old roots or bottoms of the preceding crop.

I claim as new, and desire to sceure by Letters Patent The attaching of the upper ends ofthe standards B to the frame A, by pivoting the former in mortises Z) in the latter, in connection with the rods 12 and ,the adjustable bar e attached to the draught-pole, all, arranged substantially as and for the purpose set forth.

ALEXANDER. CAMPBELL.
